general problems of the 2019 Mazda CX-5 - part 1

My 2019 Mazda Cx-5 (equipped with the 2. 5l naturally aspirated skyactiv-g engine with cylinder deactivation) has experienced a severe structural failure resulting in a cracked engine cylinder head. This casting defect allows pressurized motor oil to leak continuously from the cylinder head down onto the hot engine block and nearby exhaust components. This has led to the following severe safety risks: engine oil is leaking onto the exhaust manifold and creates an extreme risk of engine compartment fire when the vehicle is in motion; sudden loss of oil pressure or complete structural failure of the cylinder head can cause the engine to stall or seize unexpectedly without warning, completely disabling the vehicle in live traffic and creating an imminent crash hazard; and dropping oil levels and leaking fluids burning against the engine produce strong smoke and chemical odors that enter the cabin, which can cause driver distraction and severely limiting visibility if smoke escapes through the hood. We are also inhaling these odors. Mazda is fully aware of this structural engine defect and has detailed it internally under technical service bulletin TSB #sa-031-21 (as well as related tsbs for oil seepage/leaks on these cylinder heads). Despite acknowledging the manufacturing flaw, Mazda has failed to issue a safety recall for this dangerous fire and stalling hazard, forcing consumers to drive unsafe vehicles or pay thousands of dollars out of pocket for a known defect. The vehicle currently has 62,317 miles. The crack and oil leak were officially diagnosed by the carlsbad Mazda dealership service department on 5/26/26. I am requesting that the NHTSA launch a formal safety defect investigation into Mazda 2. 5l cylinder head cracking to force a safety recall before this defect leads to a fatal fire or highway accident.

This 2019 Mazda cx 5 is experiencing a crack in the oil cylinder. This appears to be connected there is no official, broad NHTSA recall for cracked oil cylinders in the 2019 Mazda Cx-5, but Mazda has issued a technical service bulletin (TSB #sa-031-21) to address this known issue. It affects certain 2018–2021 Cx-5s, particularly those with 2. 5l engines, where a cracked cylinder head leaks coolant or oil. If this is a known issue with this vehicle, why has a recall not been addressed?.

I own a 2019 Mazda Cx-5 with approximately 36,000 miles. The vehicle developed a strong burning oil smell while driving, particularly through the hvac/vent system. I initially reported the odor to a Mazda dealership, but no issue was identified. Approximately two months later, the smell returned and worsened. The vehicle was later diagnosed by a Mazda dealership with an oil leak originating from the cylinder head near the exhaust manifold. According to the repair documentation, oil was accumulating on the exhaust due to seepage from the cylinder head. The repair required full cylinder head replacement. This created significant safety concerns because leaking oil was contacting hot engine/exhaust components while the vehicle was being operated. Burning fumes entered the passenger cabin through the vents while driving. I was concerned about the risk of fire, smoke inhalation, sudden oil loss, and possible engine failure while on the road. There were no warning lights prior to the failure. The primary symptom was the persistent burning smell. The dealership replaced the cylinder head. The original repair estimate was approximately $6,000. Mazda later provided partial goodwill assistance, but I was still required to pay approximately $2,500 out of pocket. After researching this issue further, I found numerous similar NHTSA complaints involving 2019 Mazda Cx-5 vehicles experiencing cylinder head leaks/cracking near the exhaust manifold, burning smells, smoke or fumes entering the cabin, and major engine repairs at relatively low mileage. Mazda has acknowledged similar cylinder head concerns in csp11 and TSB 01-002/23 for certain VIN ranges but denied coverage for my vehicle because the leak involved oil rather than coolant and because my VIN was outside the covered range. I am requesting that NHTSA investigate whether this represents a broader cylinder head defect affecting additional 2019 Mazda Cx-5 vehicles outside the currently covered VIN range.

A Mazda dealership should me a Mazda cx5 2019, in 2023, at nearly 38k miles, right about where many have reported a cracked cylinder issue due to a manufacturing issue in age, and in milage. There is a lawsuit ongoing regarding the turbo version, however many reporting the same issue in the non turbo versions. My engine started smoking while on the highway causing a highly dangerous scenario to which I was barely able to make it to a mechanic where all the oil spilled out upon arrival. I got a diagnostic from a reputable mechanic confirming the cracked cylinder.

The cylinder head cracked, causing a coolant leak, which then lead to the car overheating. My car was taken into Mazda dealership because there is a warranty extension for this specific part csp111. The Mazda dealership, corporate, and warranty department all stated the known widespread defect cracked cylinder head will not be replaced on their behalf due to an overheating code. Mazda is using a symptom as an excuse to the problem. Due to the overheating code, Mazda recommended replacing the whole engine for $10,000 with 20 hours of labor. This defect part and Mazda’s unwillingness to provide a proper solution caused my car engine to fail, posing a safety risk. No symptoms other than low coolant were present, which my car was then parked, not driven, and towed to the dealership, in hopes the warranty would be honored.

My car has an issue officially diagnosed by a reputable mechanic that matches the claim of the former TSB sa-058/20 that was changed and clarified through the now existing TSB sa-031/21. My car has a cracked cylinder head. This is the non turbo engine but it does have cylinder deactivation which his believed to be a culprit. The cracking is known to be caused by a manufacturing defect. There is an existing class action lawsuit regarding the turbo versions. There are complexities as to wh this lawsuit is on behalf of the turbo engines, and not the non turbo engines, however the same problems are well documented and widely acknowledged throughout hundreds if not more instances of people online and by Mazda's acknowledgment of the problem through the TSB's. This put me at great safety risk. I was driving north bound right beside semi trucks and busy traffic at speed limits of 70 mph when my engine started smoking. I was able to pull over and get it to a nearby mechanic. They officially diagnosed the vehicle w the cracked cylinder head matching the aforementioned tsbs. Mazda denied my goodwill case, even though it was made without complete information on my situation and car, despite my best attempts to get to the one representing my case with the dealership(I tried to reach him for 2 days with no success). Getting a repair from Mazda dealerships was inconvenient for my location and schedule, but I've always had my vehicle properly serviced. Mazda said this repair would cost near $7500. A mechanic quoted me at least the amount of $5500.

My 2019 Mazda Cx-5 with approximately 78,000 miles developed a sudden major engine oil leak. The Mazda dealership diagnosed the issue as a cracked cylinder head and quoted approximately $5,600 for repair. The vehicle was properly maintained and this failure occurred without warning. A cylinder head failure at this mileage appears premature and may represent a defect. The oil leak created a large puddle under the vehicle and could pose a potential safety hazard due to loss of engine oil.

My 2019 Mazda Cx-5 started to smoke from the engine and I could smell oil burning. My car was due for an oil change so I brough it to a mechanic. After a diagnostic, they determined that there was a major oil leak and that the cylinder head was cracked and suggested I take it to the dealership. I did and they confirmed that there was a cracked cylinder head causing the massive oil leak. The technician even said in a video sent to me that the oil is leaking "in the same place as the others". I was then quoted $5,960. 75 to make this repair. I did research and found that this is a manufacturing defect that is long known to Mazda. There is a TSB and a cps that extends the warranty for this issue but only for turbo engines, not my non-turbo engine. My car is 2 years past the warranty but I only have 32k miles on it. I asked if Mazda could cover all or some of the cost since it is a defect, not caused by anything I did or didn't do. I was then told that because I didn't take my car there regularly for service, that they wouldn't cover it. I regularly took my car in for oil changes and other maintenance to a local shop as the nearest dealership was almost 30 miles away so it was very inconvenient. It's outrageous that Mazda won't issue a recall or extend the warranty for the same issue in the non-turbo engines. Asking me to pay $6k for a defect they caused is unconscionable.

Cylinder head is cracked and leaking oil. The cylinder head has an active warranty extension but Mazda only applies this to coolant leaks and not oil leaks. The root cause is a casting defect along with a exhaust manifold design issue that imparts undue stress onto the cylinder head causing cracks. The limitation of the warranty to the type of fluid that leaks rather than the failure due to design issues with the exhaust manifold and cylinder head does not make sense given that both components have been redesigned due to the prevalance of both coolant and oil leaks from cylinder head cracks. Problem has been confirmed by quality Mazda service departmetn on April 4, 2026 but no warranty coverage extended to repair the failure due to the fluid leak being oil and not coolant. No warnings or messages given prior to leaks. Leaks began at roughly 76,400 miles.

I am reporting a premature engine failure on my 2019 Mazda Cx-5 with approximately 55,000 miles. The vehicle developed a significant engine oil leak that was diagnosed by a repair facility as a casting failure in the cylinder head behind the timing cover. Due to the location of the leak and the nature of the defect, the entire cylinder head assembly had to be replaced. The total repair cost was $5,262. 32, which I paid out of pocket. The repair documentation indicates that Mazda has issued a technical service bulletin addressing this condition, but there is currently no recall or warranty extension covering the issue for my vehicle. A cylinder head casting failure at such low mileage appears premature and not consistent with normal wear and tear on a properly maintained engine. An engine oil leak of this nature could potentially create safety risks, including oil contamination of engine components or the possibility of oil leaking onto hot engine parts. Because this issue appears to be documented by Mazda through technical service guidance and has resulted in a costly major engine repair at relatively low mileage, I believe it should be investigated to determine whether a broader manufacturing defect exists that could affect other vehicles. I am submitting this complaint so that the issue is documented and can be evaluated for potential safety concerns or a future recall if similar failures are occurring in other vehicles.

The engine cylinder head cracked and is leaking engine oil. This component is available for inspection at liberty Mazda or by an independent certified mechanic upon request. The cracked cylinder head caused significant engine oil leakage, which created the following safety risks: sudden loss of engine power or stalling while driving smoke emission from the engine bay potential fire hazard if leaking oil contacted hot engine components these conditions placed both the driver, passengers, and others on the road at risk. The cracked cylinder head and associated oil leak were diagnosed and confirmed by liberty Mazda, the authorized dealership that performed prior repairs on this vehicle. The dealership documented the issue and provided a repair estimate of approximately $5,400. No independent service center has inspected the vehicle at this time. The vehicle and cylinder head have only been inspected by liberty Mazda. Mazda corporate has not physically inspected the vehicle, but all service records and documentation of prior repairs have been submitted to them during the warranty dispute process. There has been no inspection by police, insurance representatives, or other third parties may 2025: the vehicle intermittently struggled to accelerate. At that time, no dashboard warning lamps illuminated, and the dealership initially reported no issues. June 2025: following the timing cover repair, the vehicle experienced engine oil leakage due to incorrect sealant installation, which was documented. February 10, 2026: the dealership repaired the oil pan seal and replaced the sealant, refilling engine oil. February 14–15, 2026: approximately four to five days after the February 10 service, the cylinder head cracked, causing a significant oil leak. All symptoms and related service events are documented in liberty Mazda’s service records.

The vehicle's cylinder head has developed a structural crack at on the casting, a known manufacturing defect identified by the manufacturer in service advisory sa-037/23. This failure is causing pressurized engine oil to leak directly onto the hot exhaust manifold while the vehicle is in operation. The leaking oil is pooling on high-temperature exhaust components, creating a significant risk of fire while driving. The leak generates heavy smoke and noxious burning oil fumes that are entering the passenger cabin through the hvac system, causing respiratory issues.

The head on the 2. 4l engine of the 2019 Mazda cx5 has shown a manufacturing defect that Mazda has addressed in certain models, but not all of the models with this engine. This leaves a large amount of vehicle owners with the financial liability to pay out of pocket for Mazda's engineering and manufacturing defect that they know about. The oil leaks onto the exhaust manifold creating a fire hazard. When driving our car, we cannot use outside air on the vents, a/c because the intake pulls in smoke coming from the engine compartment. I brought the car in today to Mazda and was denied any help in the repair, I am continuing with Mazda corporate to try and reach a resolution. Currently this will be roughly a $7000 repair. I do not have an estimate yet from the dealership.

I am being told there is a crack in the cylinder head that is a known issue for these vehicles. I have done some research online and it says that they installed defective cylinders in vehicles that were made between the years 2018-2020 leaving vehicle owners to pay thousands of dollars out of pocket due to a manufacturing defect. My car was smoking and smelling like something burnt even inside the car causing the driver to inhale those fumes, I took it to the shop and it turns out that the cylinder head is cracked and leaking the oil.

My VIN indicates the 2. 5l non-turbo skyactiv engine. Many 2019 Cx-5 touring models with this engine used cylinder deactivation, which is the version that has had some cylinder head cracking complaints. The engine type has documented failures my mileage (96k) is not extremely high for an engine the repair cost is very high ($5,500+) Mazda is refusing to help me out of goodwill assistance and ive only had the car for a year. They know this is a problem and fixed it for the turbos but not the non turbos! this is ridiculous, I expected a car to last more than 96k miles this can cause a fire or a stall and can cause a crash.

The vehicle has suffered a crack of the cylinder head assembly which leads to engine oil leaking onto hot exhaust and fire hazard. This defect is officially documented by the manufacturer in service alert sa-031/21, which identifies a trend of aluminum heads cracking and leaking pressurized oil directly onto the hot exhaust manifold. Although Mazda has issued a 10-year/120,000-mile warranty extension (program csp11) for the exact same casting failure in its turbo-equipped models, it has refused to provide similar "goodwill" relief for my vehicle, despite it suffering from the identical engineering flaw. Mazda’s refusal to cover a verified latent manufacturing defect that poses a significant fire hazard is arbitrary and unfair. I am requesting that Mazda north american operations provide full reimbursement for the $6,788. 51 repair.

On 12/10/25, my 2019 cx5 na had major oil leak after smelling a burning smell for a few days. Took it into local mechanic and he couldn’t find the leak, did an engine wash and additional testing before identifying a crack in the cylinder head; the leak was coming from the exhaust manifold. There was oil all over the engine and the underbelly of the vehicle; according to the mechanic, I was lucky the car didn’t start on fire with the amount of oil. I was informed that this is a common problem with the turbos and the nas but the extended warranty only included the turbo engines. Contacted Mazda customer experience and set up an appointment. Vehicle went to the Mazda dealership on 12/15 and it was confirmed that there was a crack in the cylinder head and received an estimate of $11,000 needed for repairs. $7000 of that was for a new cylinder head. This was after an independent mechanic inspected my vehicle and stated everything looked good besides the main issue and needing new rear breaks in the next few months. 12/15-contacted Mazda customer experience and and case file was opened. 12/16-contacted customer experience back due to not receiving a call and received the name and extension of the assigned case manager. 12/17- still had not received a call back and left voicemail for case manager. Requested a call back to myself and the dealership; received a call back a few hours later and I was never asked what happened but was informed that Mazda corporate could not help me due to the warranty being expired. I am now required to pay over $250 to the dealership for an inspection of the vehicle I never requested. There were initially no warning signs but then the low oil light came on after 3 days of smelling something burning.

The 2019 Cx-5 awd with the 2. 5l na engine (with cylinder deactivation) has an engine oil leak coming from the cylinder head area. The Mazda dealer confirmed the leak source and found burnt oil on the exhaust. The component is available for inspection. The leak location and symptoms are consistent with the known porous/cracked cylinder-head defect documented in this engine family. Full confirmation requires teardown. In early Dec 2025, a burning oil smell began, then thick white smoke came from under the hood while driving and after stopping. This created an immediate fire risk, and rapid oil loss could cause sudden engine failure or stall in traffic. The issue was inspected and confirmed by an independent mechanic, who noted the leak could only be traced after removing the exhaust manifold. The Mazda dealership then inspected it and confirmed the leak source at the cylinder-head area and the burnt oil residue. The problem has been reproduced and confirmed by both the independent mechanic and the Mazda dealer. No warning lights or messages appeared prior to the smoke. Mazda has an extended warranty program for the same cylinder-head defect on the turbo engine, but no equivalent coverage exists for the na engine, despite the identical safety risks.

While driving a short distance, my engine overheated and there was a strong burning smell. The cylinder head was cracked, causing a significant oil leak. The car is currently at the dealership but is available for inspection upon request. The defective cylinder head is leaking engine oil directly onto hot exhaust components. This creates an immediate risk of engine fire and causes smoke to enter the vehicle cabin, impairing visibility and driver health. The vehicle was diagnosed by an authorized Mazda dealership. They confirmed the cylinder head is cracked and requires replacement. My mechanic advised this type of leak could lead to engine overheating, sudden power loss, or potential fire risk and should not be driven. Mazda has issued prior technical service bulletins and warranty extensions for similar cylinder head/manifold cracking issues on the 2. 5l turbo engine, but no program exists for the non-turbo engine, despite identical problems. Mazda should be held responsible for this safety issue. Mazda is aware of this manufacturing defect but has not recalled these engines to be repaired or replaced if they are outside of their warranty period, placing costly repairs and potentially life-threatening situations on their customers. The repair is replacement of the cylinder head/sleeve or replacement of the engine block, which has since been modified by Mazda to resolve this issue. Mazda’s refusal to extend reimbursement to non-turbo owners is unfair and leaves affected customers with no support for a known manufacturing flaw. I urge NHTSA to investigate this recurring engine defect in non-turbo 2019–2020 Mazda Cx-5 models and encourage Mazda to offer equal reimbursement.

The cyclinder head cracked. This could cause the engine to fail, and leaving the driver on the highway or other unsafe locations of travel. The certified repair shop along with the insurance adjuster advised it was a manufacturing defect. The warning sign was an oil burning smell inside the vehicle while stationary and inside the garage.

Question 1 - what component or system failed or malfunctioned, and is it available for inspection upon request? answer 1 - the engine cylinder head. The cylinder head developed a crack, causing a significant oil leak. The car is currently at the dealership but is available for inspection upon request. Question 2 - how was your safety or the safety of others put at risk? answer 2 - the defective cylinder head is leaking engine oil directly onto hot exhaust components. This creates an immediate risk of engine fire and causes smoke to enter the vehicle cabin, impairing visibility and driver health. Additionally, the loss of engine fluids creates a risk of sudden engine failure or stalling at highway speeds. Question 3 - has the problem been reproduced or confirmed by a dealer or independent service center answer 3 - yes. The vehicle was diagnosed by an authorized Mazda dealership. They confirmed the cylinder head is cracked and requires replacement. The dealership acknowledged the failure and offered a partial repair discount, confirming their diagnosis of the defect. Question 4 - has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? answer 4 - yes. The vehicle has been inspected by an authorized Mazda dealership technician acting as a representative for the manufacturer. I have also escalated the issue to Mazda corporate (case number can be provided upon request), who reviewed the dealership's findings but refused to cover the full repair cost. Question 5 - were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? answer 5 - I noticed an oil leak on my driveway. I noticed it and brought it in to be looked at the first week of November 2025.

2019 Mazda cx5 has a cracked cylinder head. This is causing oil to leak out. The oil is leaking out onto the exhaust manifold which is causing the manifold to smoke and has the possibility to catch fire. Mazda is aware of this issue and issued csp 11( customer service program). This does not cover the oil leak, only coolant leak. Several class action lawsuits have been filed. Local Mazda dealership has inspected the car and confirmed the issue. The issue occurred suddenly with no warning. Again, Mazda is aware of this issue but has failed to issue a recall or service program to fix it, this is a dangerous issue as it can lead to a fire with the oil leaking onto the exhaust manifold.

What component or system failed: the cylinder head failed due to cracking around the exhaust manifold, resulting in exhaust and coolant leakage. My independent mechanic and the Mazda dealer both confirmed this was the source of the burning smell and engine risk. The failed parts are currently in the possession of the Mazda dealership and available for inspection upon request. Safety risk: the failure created a strong burning rubber smell inside and outside the vehicle while driving. My mechanic advised this type of leak could lead to engine overheating, sudden power loss, or potential fire risk if not caught early. I frequently transport children in the vehicle, and the unexpected engine damage posed a significant safety concern. Has the problem been reproduced or confirmed: yes. The issue was first diagnosed by an independent, certified mechanic and then confirmed by the Mazda dealership, who determined the cylinder head had to be replaced due to premature cracking and leakage. Has the vehicle/component been inspected: yes. The vehicle has been fully inspected by an independent mechanic and the Mazda dealership service department. The dealership stated the failed cylinder head will be sent to Mazda for engineering review. Were there any warning lamps or symptoms before failure: there were no warning lights or error messages prior to the failure - which is alarming. The only initial symptom was a strong burning rubber smell that began shortly before the diagnosis. No overheating warnings appeared on the dash before the problem was confirmed. Additional context: the vehicle has 40,000 miles, has been fully maintained according to schedule, and is garage-kept. The Mazda service department acknowledged this failure is unusual and premature. Mazda has issued prior technical service bulletins and warranty extensions for similar cylinder head/manifold cracking issues on the 2. 5l turbo engine, but no program exists for the non-turbo engine, despite identical symptoms.

In August 2025, we brought our Mazda Cx-5 (non-turbo engine) to a Mazda service center and paid nearly $3,000 for repairs, including replacement of belts and other related service. Despite this, we continued to experience a burning smell from the vehicle. Shortly thereafter, the problem escalated — the burning smell persisted and smoke began to appear. Mazda is now demanding an additional $4,500 to replace a cracked cylinder head. This defect must have been present when the car was serviced in August, and the initial repairs failed to identify or correct it. While there is an NHTSA technical service bulletin for the turbo version of this engine, there are numerous complaints online about the same defect in the non-turbo model, which is what we own. This indicates that the problem is not isolated. Mazda should be held responsible for this safety issue. A cracked cylinder head that leads to burning smells and smoke is a serious hazard that could cause engine failure or even fire. Consumers should not be forced to spend thousands of dollars on repairs for what appears to be a widespread defect and when our vehicle has only $50k miles and it should last for the life of the vehicle.

The contact owns a 2019 Mazda Cx-5. The contact stated that while driving 30 mph with a toddler occupying the rear seat, the contact noticed smoke and an abnormal burning rubber odor coming through the vents. The contact pulled into a gas station and then pulled into a nail salon parking lot. There was no warning light illuminated. The contact was able to drive to the residence, where an independent mechanic inspected the vehicle and found an oil leak, and the mechanic diagnosed that the cylinder head had cracked. The vehicle was taken to the dealer. The dealer informed the contact that the repair could not be covered under an unknown extended warranty because of the type of engine. The manufacturer was notified of the failure and informed the contact that the repair could not be covered under goodwill assistance because the oil changes had not been mainly performed by the dealer. The vehicle was not repaired. The failure mileage was approximately 83,000.

Drove 39 miles, around ~55 minutes. Parked the car, realized that I parked a little too far from the spot, car just stalled while rolling. Pressed accelerator, nothing. Turned off the car, tried to start again, it cranked but didn't start. Had to tow it to the nearest mechanic (total of ~2 hrs until my car got picked up and dropped off), mechanic calls me and tells me my car started fine. I'm thinking it could be 5321k recall but not sure as my VIN is not in the recall nor did I get any recall notice. What component or system failed or malfunctioned, and is it available for inspection upon request? - no idea. How was your safety or the safety of others put at risk? - got stranded for hours in the parking lot. Has the problem been reproduced or confirmed by a dealer or independent service center? - no has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - no were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - yes, fuel cap like icon and check engine light were on when trying to start the car after it stalled. The car would crank but not start.

Confirmed cracked cylinder by dealership, led to dumping of oil while vehicle was in motion on the highway. Vehicle/engine could have caught fire at any moment. There were no engine warnings that appeared on the dash. This is consistent with other Cx-5 complaints on NHTSA. Vehicle had 55,000 miles on it at time of incident, and needed $8,000 worth of repair. Please recall!!.

Cracked/leaking cylinder head on my 2019 Mazda cx5. It is understood that Mazda has extended warranty for the turbo model (csp11) of this car, but not the standard engine, even though they both are displaying the same issue in many 2019 cx5s. Quoted at $6000 for a vehicle under 90k miles. Issue needs to be escalated.

Dealership service department found a cracked cylinder head. This issue has been reported to NHTSA by Mazda. The car is being serviced and this issue was found. I’m attaching photos and also report from dealership l.

Cracked cylinder head.

Timing cover oil leak. This is the same issue reported in technical bulletin #01-006/23 issued on 04/26/2023. There is oil leaking and the engine is smoking. No engine warning lights or other messages appeared. My car is a 2019 Mazda Cx-5 and has 31,954 miles. This problem has been confirmed by both an independent mechanic and the dealer service center. On 08/22/2025, I took my vehicle to dealer service for the repair. I also submitted a ticket to Mazda care for review of the case.

For the 3rd or 4th time since I have own this car I experienced a loss of acceleration when attempting to make quick acceleration while attempting to merge with traffic. Acceleration is fine around town where quick acceleration is not appropriate. But the first attempt to merge with flowing traffic the car will slowly accelerates to about 30 mph and no more regardless as to position of accelerator pedal. On all occasion this bad behavior has this first drive of the day - going to work in the a. M. There is often a warning message indicating the safety radar is not working due to limited visibility which is a very common warning in the a. M.

My vehicle has 64k miles and has had regular maintenance - oil changes, etc. It has recently developed an oil leak. I took it to the dealer today & they said the cylinder head and gasket needs to be replaced. My car has not overheating or even run warm. I understand there are 2019 Cx-5s that have had a casting issue with cylinder heads. I feel sure that’s what the issue is here yet they want almost $6k to repair my vehicle!.

The contact owns a 2019 Mazda Cx-5. The contact stated that while operating the vehicle, the message that the engine oil level was low was displayed. The contact stated that oil was added to the engine; however, the next day the message reoccurred. The contact stated that later while the vehicle was parked, the contact discovered an oil leak underneath the vehicle. The vehicle was driven to the local mechanic who confirmed oil leaking from the engine, but the cause of the oil leak was not yet determined. The local dealer was contacted, and a service appointment was scheduled. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The manufacturer was not contacted about the failure. The failure mileage was 96,600.

Just got diagnosed with cracked cylinder head. After looking on social media, it appears this is a thing for the model years 2018 and 2019. Bad casting? anyway I believe this should be a voluntary recall to correct such a flawed engine. I bought this new from a Mazda dealership and kept it up to date with service only through the dealer. The 60 month/60,000 mile drive train warranty ran out last July. However I only have 50,000 miles on the car. . . Babied.
