2021 Mazda Cx-5 2. 5l non-turbo. While driving at approximately 8 mph, I removed my foot from the accelerator, but the vehicle unexpectedly accelerated on its own. I did not press the accelerator pedal. I had to apply the brake to slow the vehicle down. This issue has occurred three separate times, on August 25, September 4, and September 18, 2026, at approximately 70,060 miles. The same unintended acceleration behavior occurred during all three incidents.

Differential went and generated a cascading chain reaction destroying the coupler and breather and axles. Car is undrivable. This. Defect has a TSB.

2018 Mazda Cx-5 2. 5l na engine cracked cylinder head and blown head gasket with leaking oil onto exhaust manifold resulting in white smoke & burning oil smell. No engine light. Issue confirmed by dealer and independent shop. Commonly reported issue amongst 2018-2021 Mazda Cx-5 owners either naturally aspirated engines.

My 2017 Mazda Cx-5 has experienced a recurring condition more than six times involving sudden jerking, rapid deceleration, and loss of normal accelerator response during extended highway driving, often while cruise control is engaged. On multiple occasions the engine has also shut down. On 09/11/2026, while traveling south on I-35 at approximately 80 mph with cruise control engaged, the vehicle suddenly began jerking violently and rapidly losing speed. Normal accelerator response was lost and a vehicle behind me nearly struck my vehicle. I was able to reach the shoulder just before the engine shut down. The vehicle would not restart and required towing. There was little or no meaningful warning before the loss of power. The vehicle was inspected by a Mazda dealer. I specifically reported the recurring highway jerking, deceleration, loss of throttle response, and shutdown concern. An aftermarket obd-ii device was removed after the dealer identified parasitic battery draw. The dealer subsequently stated in writing that the battery and alternator were healthy and that the vehicle was “operating as intended. ” on 10/09/2026, with that device no longer installed, the same symptoms occurred again during highway travel and the vehicle again became disabled and required towing. The Mazda dealer has now verified the drivability concern and reported a fuel rail pressure sensor “a” circuit low fault and low fuel pressure. The dealer is recommending replacement of the high-pressure fuel pump as an initial repair, followed by further testing of the in-tank fuel pump. The vehicle is currently available for inspection at the Mazda dealer. Nhtsa’s VIN lookup currently shows 0 unrepaired recalls. I am reporting this because sudden loss of acceleration and power at highway speed creates a serious collision and roadside safety risk.

The contact owns a 2021 Mazda Cx-5. The contact stated that while driving 50 mph and the check engine warning light illuminated. The contact took the vehicle to an independent mechanic where an obdii scanner discovered a misfire in cylinder#1. The vehicle was then taken to another independent mechanic where the obdii scanner discovered a misfire in one of the engine cylinders and diagnosed the vehicle with an engine failure. The contact was then referred to the dealer who confirmed that there was a defect with cylinder#1. The dealer confirmed that the engine needed to be replaced. The manufacturer was then notified of the failure, and the contact was informed that there were no recalls on the vehicle and that the warranty had expired. The vehicle was taken to another independent mechanic and remained with the independent mechanic. The failure mileage was approximately 124,000.

2025 Mazda Cx-5. The vehicle experienced a severe, dynamic charging system failure that creates an active safety hazard on public roads. A dealership service department attempted a software update, which turned off the active dashboard layout indicator but completely failed to resolve the root hardware issue. The system failure remains active and has thrown consecutive advanced safety system faults. Vehicle diagnostic timeline & brief •vehicle: 2025 Mazda Cx-5 •warranty status: active (under bumper-to-bumper new-vehicle limited warranty) •modifications: none (100% factory standard; no aftermarket accessories) on the evening of September 11th, 2026, while preparing to leave on a cross-country trip, the car would not start. It was originally believed it was because while loading the car we left one of the key fobs in the car and tried to lock the doors. We reset the fob and tried the manual override to get the car to start with no luck. There were several warning lights coming up on dash to include an istop warning. Unfortunately, I didn't take pictures of the original incident. We contacted aaa and they came and jump started the car. We left on our trip the morning of September 12th, 2026. The car started with no issue. That afternoon as we were driving through a small town, we stopped at a traffic light and received the "battery malfunction" warring light. We headed to auto zone, they checked the battery and said it had low charge, even though we had just driven the car over 400 miles. We parked the car at the hotel fulling expect to have to call aaa again but the next morning the car started without a problem. On September 13th, 2026, we continued our trip. When we stopped for gas that afternoon the car would not start. We again had to jump it. When we left the gas station the check engine light came on (amber). We were close to wichita falls, TX so we stopped for the day and made an appointment with the dealership there for the n.

The vehicle exhibits a repeatable low-speed driveline-related problem consisting of pronounced clicking or clunking from the driver-front area, fore-and-aft jerking, and harsh engagement during deceleration and light on/off-throttle transitions, particularly around 15–17 mph; the behavior can become significantly worse over rough or uneven terrain. The exact failed component or system has not yet been identified. The vehicle is still essentially new, with fewer than 5,000 miles, and has not yet reached its first scheduled service interval, so it has not yet been formally inspected for this condition. No warning lamp or diagnostic message has appeared. Other owners online have described a similar low-speed clunking and jerking phenomenon, and Mazda has issued at least one prior transmission-related TSB addressing somewhat similar harsh shift behavior, although that bulletin does not appear to apply to this vehicle or this exact symptom. The vehicle is available for inspection upon request. The concern presents a potential safety risk because the vehicle can unexpectedly jerk, lurch, or abruptly change driveline load during ordinary low-speed driving, which can make accelerator response and vehicle speed less predictable in traffic, parking lots, intersections, or on uneven surfaces. The symptoms began within the first few thousand miles and remain repeatable.

2019 Mazda Cx-5 developed p0192-00 fuel-pressure-related fault and significant loss of acceleration/limp mode. Mazda dealership diagnosed fuel rail/injector-seal issue and performed approximately $2,836 in repairs. The condition was not corrected. Dealer now diagnoses a high-pressure fuel-pump failure and is requesting an additional $1,459. Vehicle has experienced loss of power while driving. There is an existing Mazda fuel-pump recall affecting some 2018–2019 Cx-5 vehicles, but Mazda says my VIN is outside the recall population. I am concerned about a potential fuel-system safety defect.

The contact owns a 2018 Mazda Cx-5. The contact stated that while driving at various speeds, the vehicle was leaking engine oil, and there was white smoke coming from underneath the hood. The contact stated that upon further inspection, there was a puddle of engine oil on the ground while the vehicle was idling. No warning light was illuminated. The vehicle was towed to a local dealer, where it was diagnosed with a cracked cylinder head. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 183,540.

The contact owns a 2019 Mazda Cx-5. The contact stated that while driving at 55 mph and turning into a driveway, smoke emerged from the engine compartment. The vehicle was turned off and inspected. Upon opening the hood, smoke was observed near the rear firewall of the engine compartment, and oil was leaking under the engine compartment. The source of the leak could not be identified initially, and the vehicle was towed to an independent mechanic, where a leaking cylinder head was diagnosed. The vehicle was not repaired. The vehicle was then taken to a dealer, where it was confirmed that the cylinder head was leaking oil and needed replacement. The vehicle was not repaired. The manufacturer was notified of the failure, and a complaint was filed. The failure mileage was approximately 100,000.

I own a 2019 Mazda Cx-5 awd equipped with the 2. 5l naturally aspirated skyactiv-g engine with cylinder deactivation. At approximately 70,491 miles, the vehicle began leaking and burning engine oil, accompanied by a strong burning-oil odor and visible white smoke from the engine bay. This began on or around 7/15/2026 I took the vehicle to an authorized Mazda dealer, which confirmed that the cylinder head is cracked and leaking engine oil. I was quoted approximately $10,000 to repair. The repair is not covered because the vehicle is just outside the factory warranty. I received regular Mazda dealership maintenance through 52,000 miles, then regular 3rd party shops after. The oil is leaking onto/near the exhaust manifold. Oil contacting the hot exhaust creates a serious fire hazard, which I can detect from the burning-oil odor and smoke. Separately, ongoing oil loss risks sudden engine failure or stalling while driving, which could cause a loss of motive power and a crash, especially at highway speed or in traffic. This appears to be a widespread manufacturing defect. Many owners of 2018–2021 Mazda Cx-5, and related Mazda3 and Mazda6 vehicles equipped with the 2. 5l naturally aspirated engine with cylinder deactivation, have reported the identical failure — cylinder head cracking near the exhaust manifold causing an oil leak — frequently at low mileage. Mazda issued an internal service alert (sa-058/20) addressing cylinder head cracking on these engines, which shows the manufacturer is aware of the defect. Despite this, affected non-turbo owners are being denied repair assistance and are paying thousands of dollars out of pocket to fix a defect that presents a fire and crash risk. No crash, fire, or injury has occurred. I am reporting this because the defect is safety-related, appears to affect a large number of identically built vehicles, and warrants investigation and a potential recall to protect owners — especially those outside the warranty period.

The vehicle experienced a sudden and complete engine stall while idling immediately after fueling the gas tank to capacity on a day with high ambient temperatures (over 100°f). Leading up to the stall, the vehicle was subjected to temporary auxiliary loads (max ac running and active steering input). Immediately following the stall, the vehicle exhibited a hard-start condition and would not catch fire. After sitting turned off for several minutes, the vehicle restarted normally. The incident left no diagnostic trouble codes (dtcs) or check engine lights. Independent of this event, the vehicle intermittently exhibits a raw gasoline vapor smell inside the cabin at idle, alongside slight hesitations during low-speed steering maneuvers. This presents a safety hazard due to unexpected loss of motive power immediately after refueling in high-traffic gas station environments.

The contact owns a 2018 Mazda Cx-5. The contact stated that white smoke was coming from the engine compartment whenever the vehicle reached normal operating temperature. The contact stated that smoke entered the passenger’s side compartment through the air vents and was coming from underneath the hood. The contact stated that there was a burning odor coming from the engine compartment due to an oil leakage. The smoke impaired visibility while driving. The most recent failure had occurred while driving approximately 35 mph on a city roadway. The vehicle was driven to an independent mechanic to be diagnosed, and then to the dealer for further inspection. The independent mechanic diagnosed the vehicle with a cracked cylinder head and recommended that the vehicle be taken to the dealer for additional diagnostic tests. The dealer diagnosed the cylinder head as porous and informed the contact that the cylinder head needed to be replaced. The manufacturer was notified and informed the contact that the repair would not be covered. The vehicle was not repaired. The contact stated that the failure had occurred intermittently and became more frequent and severe during hotter weather. The failure mileage was approximately 83,000.

The vehicle developed an engine oil leak from the timing cover due to what appears to be premature seal failure. Engine oil was leaking externally and could drip onto hot engine components, creating a potential fire hazard while the vehicle is in operation. The leak also increases the risk of low engine oil levels, which could lead to engine damage or sudden engine failure if not detected in time. This issue required an expensive repair despite the vehicle being properly maintained. I have since learned that many other Mazda owners have reported similar timing cover oil leaks on this engine, suggesting this may be a widespread defect rather than normal wear and tear. I am submitting this complaint so NHTSA can evaluate whether this represents a safety-related defect that warrants further investigation.

The contact owns a 2018 Mazda Cx-5. The contact stated that while his wife was driving at an undisclosed speed, there was smoke coming from under the hood. No warning light was illuminated. The contact's wife pulled over and discovered that there was oil leaking onto the ground. The vehicle was towed to the dealer, who determined that the #5 and #7 cylinder heads were cracked and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 100,000.

I am the owner of a 2019 Mazda Cx-5 with approximately 50,000 miles. I am experiencing an active engine oil leak accompanied by a burning smell and visible smoke from the engine compartment. This is consistent with a cracked cylinder head assembly — a known manufacturing defect in 2018–2021 Mazda Cx-5 vehicles documented in Mazda's own service alert sa-031/21, which Mazda characterizes as a fire hazard. Despite this, Mazda has extended warranty coverage only to turbo-equipped models (program csp11), leaving non-turbo owners with the identical defect unprotected. At only 50,000 miles, this is a premature failure caused by a manufacturing defect — not normal wear and tear. Oil leaking onto a hot exhaust manifold constitutes a serious fire risk to vehicle occupants and the public. I am requesting that NHTSA investigate this pattern of failure across 2018–2021 Mazda Cx-5 non-turbo models and consider whether a formal recall is warranted. I have contacted Mazda north american operations directly requesting goodwill warranty coverage and have a case number on file. I have yet to hear a response but was initially informed my car was out of warranty.

Check engine light code p0524 - low oil pressure. Everything check out fine. Checked all the suggested TSB (technical service bulletin) possibilities from a respected and qualified service center. Cleared the code and it keeps coming back on.

I am submitting this complaint regarding a cylinder head failure on my Mazda Cx-5. The vehicle has approximately 53,000 miles and has been properly maintained throughout its service life. The vehicle developed a crack in the cylinder head, which was subsequently confirmed by an authorized Mazda dealership. Mazda has previously issued a technical service bulletin (TSB) addressing cylinder head cracking on certain vehicles; however, my vehicle's VIN is not included in the covered range despite experiencing the same failure described in the TSB. The dealership initially provided a repair estimate of $8,789 plus tax to replace the cylinder head. Following further discussions, the dealership reduced the repair cost to $3,903 plus tax. They recognize that this crack is not part of normal wear and tear but due to the VIN number not being included in the recall are unable to provide full coverage. A cylinder head crack is a major engine failure that should not occur on a well-maintained vehicle with only 53,000 miles. I am concerned that vehicles outside the VIN range identified in Mazda's TSB may be experiencing the same defect and that the scope of the issue may be broader than currently recognized. The vehicle was purchased used from the same Mazda dealership that diagnosed the failure and is currently performing the repair evaluation. I respectfully request that NHTSA review this issue to determine whether additional Mazda Cx-5 vehicles may be affected by the same cylinder head defect despite not being included in the existing TSB.

I purchased a used 2019 Mazda Cx-5 in 2024, with 25,000 miles on it. In June of 2026 I started to have an oil leak. Took it to a mechanic's shop who diagnosed it as a valve cover gasket, ran the car for another 2 months, oil leak did not stop, got worse, to the point where my oil light came on where the oil was low enough, then I took it to another mechanic, they diagnosed it as some sort of pressure sensor that has to do with the oil, they replaced that, then that still wasn't the case, it was leaking, and they diagnosed it as a cracked cylinder head. This has been an issue with Mazdas in the 2018 to 2022 range for the Cx-5s, and Mazda knowingly has put in faulty parts and is not willing to extend the warranty on this because it's not a turbo, this is a clever work around to avoid paying for something that should not be going out at this point. For this car being under 60,000 miles, been taking very good care of it, always had the oil changed, I feel that this is not fair for the customer to have to replace something on an engine that shouldn't be addressed for a very long time, if at all. I contacted Mazda corporate, they refused to do anything about it, I also contacted the Mazda dealership in my area, they contacted Mazda corporate and are not willing to cover this as well, my parents had a Mazda back in 2008 that had a similar problem. The only way this was resolved was going through Mazda corporate and writing a stern letter to their management team. At this point I've basically lost the trust of this manufacturer. I spent 25,000 dollars on this car, and now I'm going to have to spend 7 to 8 thousand dollars to get this part replaced, and that this point in the car’s life, that is outrageous. I will not be purchasing from Mazda ever again, there is plenty of documentation on the internet about this problem, and that Mazda refuses to do anything about it.

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.

My car caught on fire on [ccc] and it's completely burned down, a total loss. Following is information about my car and some summary of what happened. Car information: - Mazda cx5 2024 - bought in June or July 2024(car payment only made 22 times so far) - odometer 24,445mi(as of 05/15/2026) what happened: - in [xxx] Friday afternoon, I was in bellevue and noticed an engine overheat warning. So, I stopped immediately to cool down and called Mazda dealership(lee johnson Mazda) to schedule a service. - then after 20-30 minutes, I started the car again and the warning was gone. So I drove slowly and got on [xxx] to head home in kirkland. I was already driving slowly. - after a few minutes, overheat warning as well as engine warning started firing and noticed that smoke coming out of bonnet. - so, I pulled over on the shoulder near [xxx] and called roadside assistance. But even before I get connected to the roadside service, engine caught on fire and I had to call 911. - the car is completely burned down and it's a total loss. - state patrol wrote me a "exchange of information" and "tow/impound and inventory record". Why I am submitting this form: - this car is less than 2years old and has been seeing Mazda service regularly. The odometer checked by dealership on 05/15 is 24,445mi which is slightly more than 24,000 which is stated in the lemon law. But still, the car is pretty brand new and around 24,000 ish. So, I'm wondering if this still qualifies for lemon law. - even before this happened, I had a service history for engine warning and get the engine checked on 05/15/2026 which is exactly a week ago before the accident. Also, they said the engine thermostat had an issue and replaced and covered by Mazda's warranty. - overheat and engine warning was on and off. As soon as I pull over, it caught on fire. - this happened on [xxx]. It was very dangerous and lucky that we pulled over on right before it caught on fire information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Cylinder head has failed at 53,000 miles. Mazda has a technical service bulletin acknowledging that this is a common occurrence with this part. They have an extended warranty for the turbo engine but not for the standard engine. Looking through online forums, there are hundreds of not thousands of these issues for this model year and engine. Mazda has clearly acknowledged there is an issue and should repair these manufacturing defects that are not normal wear and tear items.

On may 21st , 2026, while waiting in line to make a right turn (positioned 3rd in queue), the vehicles ahead moved forward. As I transitioned from the brake to the gas pedal to follow, the vehicle experienced an instantaneous engine stall and total electrical failure (not an I-stop event). Pressing the gas caused the vehicle to slowly roll backward. When I immediately tried to reapply the brakes, the brake pedal became extremely stiff and nearly impossible to press down, failing to hold the vehicle effectively. The driver behind me began honking aggressively due to the imminent collision risk. I attempted to lower the windows to signal the other driver, but all electronic controls were completely dead. I had to quickly shift the gear into park (p) and hit the start button to successfully restart the engine, which temporarily restored functions.

Cylinder block cracked on back side of engine. This crack leaks oil onto the exhaust manifold. Condition confirmed by Mazda dealer. Oil burns on the exhaust filling the cabin with smoke impairing the driver. Also a high risk of combustion in the engine compartment inspection report and pictures available. No sign or warning of issue. Crack happened on a daily drive to work. No engine lights noise or smell until head suddenly cracked causing a large oil leak. Mazda has an internal TSB 01-002/23 admitting that these cars in this year range have a manufacturer defect in the block.

We purchased this vehicle used from Mazda of orange in July 2025 with 52,399 miles on it. After 6 months of ownership and approximately 3,000 miles there was a burning smell. We took it to our local mechanic and the following repairs were required: replacement of cracked belts, replacement of cracked axle boots, replacement of an excessively loose front axle, replacement of valve cover gasket. Cost was $3,000 and the dealer refused to reimburse us. Now the car is leaking oil and needs a new head gasket and cylinder head surface machined. Quote was approximately $3,500. We have requested Mazda perform this repair. Will you please look into these vehicles? these are significant defects on a car with such low miles. We also believe that some of these defects were know to the dealer but are unable to prove it. We believe our vehicle is part of a batch that has signficant mechanical defects. Current mileage of the vehicle is 56,865.

Like many other complaints. My 2018 Mazda cx5 gt is having the same issue with the cracked cylinder head. I only have about 36-38k mileage on it ( I forgot the exact). Mazda dealership will not cover the cost. Never had an accident to the front and only one accident to the back when I got rear ended in 2019. If this is a wide spread issue, why is this not a recall? and why is it only the turbo engine gets extended warranty? the repair cost right now approximately $9,500. I never do any maintenance at Mazda so I doubt they will give me the good will assistance but I am still waiting for an answer. I hope nhsta will do something because this issue will continue with all other owners that have the same year model.

The cylinder head has cracked and is leaking externally. The engine oil that is leaking out is leaking directly onto the hot exhaust manifold. This can place us as risk due to the engine oil getting ignited by the hot exhaust manifold. There were no warning lamps that came on but there was a smell of burning oil that all of a sudden came up through the vents. This vehicle is currently at woodhouse Mazda in bellevue, ne and they have confirmed that the leak is active and has damaged the engine beyond repair.

On may 11th I was driving my 2019 Mazda Cx-5 with approximately 35,000 miles when my cabin filled with the smell of gasoline. The smell became overwhelming within minutes, causing concern for my safety and the safety of other drivers. I immediately drove to the closest auto repair/body shop for an emergency inspection. Upon inspection, the technicians discovered there was a "crack at rear cylinder head and leaking oil excessively. Oil is leaking on to hot exhaust manifold. . . . Car is not safe to drive since oil leak is excessive". I was advised that this must be a manufacturer defect as you should not see this issue at such low mileage. The vehicle was then towed to the nearest Mazda dealership/service center, where a cracked rear cylinder head was diagnosed and confirmed. I was informed that continued operation of the vehicle could have resulted in catastrophic engine failure, engine seizure, fire risk from leaking oil contacting hot engine components, or sudden loss of power while driving, creating an extremely dangerous driving situation. Prior to the failure, there were no major warning indicators other than the sudden strong fuel/oil smell. The issue occurred unexpectedly despite the vehicle being properly maintained and having low mileage for a major engine failure. I have been the sole owner. The vehicle is currently available for inspection upon request.

Timing chain cover ended up leaking oil everywhere. Was told this was a known issue with Mazda Cx-5 and there was even a service bulletin out.

My 2021 Mazda cx?5 is experiencing excessive oil consumption. The vehicle is burning oil between regular oil changes, and the oil level drops noticeably before the recommended service interval. I have noticed a burning smell and/or signs of oil loss without visible leaks. This raises concerns about potential engine damage, stalling, or fire risk while driving. The issue has occurred repeatedly and does not seem normal for a vehicle of this age and mileage. I am filing this complaint because this may indicate a defect affecting engine safety and reliability.

The contact owns a 2017 Mazda Cx-5. While driving the vehicle, the engine overheat warning suddenly illuminated on the dashboard cluster panel. The contact pulled over immediately, restarted the engine, and coasted the vehicle to a local, independent mechanic shop. The independent mechanic diagnosed the issue as a blown head gasket. For a secondary inspection, the vehicle was transported to an authorized Mazda dealership. Dealership technicians determined that the engine cylinder was actually cracked and recommended a full engine replacement. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 92,000.

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?.

2021 Mazda cx?5 (VIN: [xxx] ). First low?oil warning at 17,800 miles. ([xxx]) Mazda dealership in la crosse, WI performed an oil change and fully refilled the oil. Second low?oil warning at 18,700 miles — only 900 miles later. ([xxx]) this indicates rapid, abnormal oil loss consistent with the known valve?stem?seal defect for this model year. Sudden low?oil conditions pose a safety risk due to potential engine damage or failure. Requesting NHTSA document this issue. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
