Engine And Engine Cooling Problems of Volkswagen Tiguan - part 1

I am filing this complaint because my Volkswagen Tiguan has a serious and ongoing engine issue involving excessive oil consumption and a faulty cylinder head. The vehicle burns through an abnormal amount of oil between changes, requiring constant top?offs, sometimes as frequently as every few hundred miles. Despite regularly adding oil and following all manufacturer?recommended maintenance, the issue continues to worsen. The dealership has confirmed that the cylinder head is defective, which is causing the engine to consume oil at an extremely accelerated rate. However, I have been told the replacement cylinder head is on national backorder, and there is currently no estimated timeframe for when the part will be available. This means I am forced to continue driving a vehicle with a known, documented engine defect that can: lead to engine stalling create loss of power while driving increase the risk of engine seizure potentially cause a safety hazard on the road additionally, being required to constantly add oil just to keep the vehicle operable is not only unsafe but financially unreasonable. The problem remains unresolved despite multiple service visits, documentation, and repeated oil consumption tests. This is a safety issue, not just a maintenance concern, because the engine can fail unexpectedly if the oil drops too quickly. I believe this is a significant defect affecting multiple Volkswagen vehicles and should be investigated by NHTSA. I request that NHTSA open a formal investigation into the excessive oil consumption and cylinder head defects on Volkswagen Tiguans, as owners should not be left with unsafe vehicles due to known manufacturing issues and unavailable critical engine components.

Check engine light came on, related to the thermostat and faulty water pump. My car’s make and model was part of a settlement for this issue but vw corporate will not cover costs to repair.

The contact owns a 2023 Volkswagen Tiguan. The contact stated that while driving at an undisclosed speed, the low oil warning light unexpectedly illuminated. The failure persisted even after the vehicle had received several oil changes. The vehicle was taken to the dealer, but was not diagnosed or repaired. The contact was informed that an oil change was completed; however, the failure persisted. The vehicle was taken back to the dealer where it was diagnosed that the valve stem seal had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 72,061.

The cylinder head has passages that collect carbon build up that build up outside of general maintenance that clog the cylinder head and can eventually lead to combustion failure. This car has been taken to an independent, reputable mechanic in the area, as well as now the dealer. Dealer has confirmed they have at least 4 other vehicles currently with the same issue in just this one location, and parts replacement to remedy the issue (new cylinder heads) are on back order (over 2500 on order in us). This car has been caught early, before this engine failure, as the check engine light first came up and multiple rounds of mechanic checking and trying to fix have lead to this conclusion. Car at this time has not failed in a safety situation, but has the potential to if not remedied, by engine failing while driving. Engine has been inspected by mechanic, and is currently being inspected by manufacturer. Error code was presented once reading the module, and check engine light is visible to prompt servicing the car (code for emissions).

While driving at road speed, the vehicle unexpectedly shifted itself into neutral (n) without driver input. The engine continued running, but the vehicle lost drive power. Simultaneously, the dashboard displayed multiple warning indicators including: “exhaust system malfunction” warning semi-automated driving assistance warning sos / emergency system warning the driver safely pulled to the roadside and turned the vehicle off. Upon first restart, the vehicle would not shift into drive. After turning the vehicle off again and waiting approximately 30 seconds, it restarted and allowed drive engagement. The “exhaust system malfunction” warning remained illuminated for the remainder of the trip. The vehicle was taken to a Volkswagen dealer. The dealer was unable to duplicate the condition after a 50-mile drive. Dealer reported only a rear radar fault code and stated no other diagnostic trouble codes were stored. Warning lights had cleared by the time of inspection. This was an unintended transmission disengagement event while in motion. The loss of drive power at speed presents a safety hazard. The vehicle is a 2025 Volkswagen Tiguan built mid-2025 and currently has approximately 1000 miles.

Since buying the car in August 2025, I've had multiple issues. Ive had a noise coming from the front passenger side of the vehicle, brought it in and they could not identify the issue or fix it, to this day I still have this noise coming from the front passenger side. Furthermore, I've had numerous hazard lights come on the dash, lasting 2-4 days and then disappearing and reappearing later on. These lights include the check engine light, oil leaks, and not allowing the car to drive over a certain limit due to engine issues. I've also brought these issues to the service center so they can diagnose and fix the issue. They are unable to find anything wrong. Most dangerous event is the car completely shut down on me while driving. This is extremely dangerous to not only myself but others around me. I brought this concern to the service center and they could not figure out why this happened. This car is unsafe to drive.

Turbocharger failed. This new car was one week old and had approximately one hundred miles on it. There are numerous reports of this condition online. The car can no longer be driven and the part is on national backorder.

Loss of acceleration. Errors. Turbo failure before 3,000k miles. Received five errors alerts at once: 1. Emergency assist not available 2. Engine speed max 4000rpm 3. Error: drive system currently unavailable 4. Error: cruise control system 5. Travel assist currently unavailable. Initial occurrence was misdiagnosed at dealership as a computer system failure. They cleared the alerts but not the problem. Returned to service a second time (currently there) and they identified the turbo needs full replacement and it is not safe to drive. No eta on a fix “due to parts back ordered”; potentially mid-March.

Our vehicle became unable to shift out of neutral after a traction event (wheel slip & loss of traction) when trying back into our driveway from a snow packed access alleyway then multiple system warnings occurred including transmission, traction control, abs, engine ecu, stability systems and anti-roll errors. I turned off the car and tried again with vehicle still unable to shift out of neutral with the multiple system warnings again occurring. I turned the vehicle off for a longer duration (10 minutes) while calling the service department at the dealership asking if our car should be towed. I turned the vehicle on again and it did go into drive and reverse but the check engine light displayed. Remote start no longer functions. Failsafe modes are not supposed to leave the car unable to shift out of neutral without warning! the fact that it threw multiple system errors at once, refused to shift, then later shifted after a longer power-down, and now has a check engine light strongly suggests a stored hard fault, not just a transient glitch. From a safety and regulatory standpoint, loss of motive control without driver input amounts to a reportable safety defect.  if this didn’t happen while trying to park in my driveway, it could’ve been much worse. If this had happened in traffic, while pulling into an intersection, on a hill, during a snowstorm, or while backing into traffic, the inability to shift could have caused a collision. I did report this to vw customer care and they immediately escalated this to a case manager. The vehicle was dropped off to the dealership this morning and will be discussing the event with the service manager on Monday and that I want  all stored fault codes printed, confirmation whether this triggered limp/failsafe logic, and what prevents it from happening again.  the vw case manager will also be contacting the dealership directly. The bottom line is that I do not feel safe operating this vehicle until the root cause is identified.  .

The contact owns a 2020 Volkswagen Tiguan. The contact stated that the engine warning light was illuminated due to an emissions issue. The message to check the oil level was displayed. The contact pulled over to check the oil and added a quart of oil. The vehicle was consuming an excessive amount of engine oil. The vehicle was taken to an independent mechanic who determined that there was smoke coming from the exhaust. The contact was informed that the cylinder head valve seals had failed and caused oil to seep through the exhaust ports and was burning oil on the second head emissions system and the port was clogged. Additionally, the back over prevention camera was inoperable. The contact determined that the top half of the engine needed to be replaced. The cylinder head was on backorder. The local dealer was not contacted, and the vehicle was not diagnosed or repaired. The vehicle was not under warranty. The manufacturer was not notified of the failure. The failure mileage was approximately 55,000.

Oil light continues to come on after about 1,000-1,500 miles after an oil change. This has happen several times now and I have to put oil in it to keep it from ruining the engine. I see hat there have been complaints about this already with these models with excessive oil consumption and even engine failure. This needs to be fixed.

I am filing a safety complaint regarding a serious transmission defect in my vehicle. The drive and reverse gears are not functioning properly. After driving for a few minutes and parking, when I attempt to reverse on an inclined surface, the vehicle unexpectedly moves forward instead of backward. Similarly, when the vehicle is parked facing downhill and I shift into drive to move forward, it rolls backward. There are no warning lights or dashboard indicators alerting me to any malfunction. Due to this defect, I have nearly collided with objects multiple times within just 15 days of ownership. Most concerning, I almost hit another vehicle behind me while attempting to drive forward, as my vehicle suddenly rolled backward unexpectedly. This creates a serious safety hazard for me, my passengers, and other drivers. I purchased this used vehicle with less than 10,000 miles from echopark dealership. Unfortunately, I am unable to return the vehicle because their return policy is limited to 7 days. However, this issue appears to be a significant mechanical or transmission defect that poses an immediate safety risk.

The engine started smoking at 11,000 and new valve seals were replaced in the head. The engine has started to smoke again at 16,800 mile and dealer said the next step would be to replace the head. Car has been to the dealer 6-7 times for electrical and engine problems. The sos light comes on almost every morning. Driver seat memory does not work and dealer can't figure it out after 5-6 times, they have replaced about everything on the seat and it still doesn't work.

5 complaints about oil consumption, 3 check engine lights where had to pull over due to car not running properly. Vehicle putters upon acceleration. Replaced leak detection pump, intake and exhaust system stem seals, oil separator, auxiliary bracket and seal and evap sensor.

I was at a complete stop at the red light, vehicle began shaking and shut down. Gears would not work therefore I was not able to put it in neutral to at least push out of the road. The vehicle then began cranking on and off on its own, without me pushing start/stop engine. This was completely unexpected as the truck is one week old, had a full tank of gas and it was especially dangerous to have shut down on a busy highway. Also when reversing the vehicle makes a weird click noise.

On December 3, 2025, Volkswagen of xxx performed an intake manifold recall repair on our 2017 Tiguan (VIN: [xxx] ) while the vehicle was under factory warranty. Approximately six weeks later the low coolant warning light appeared and the vehicle began actively leaking coolant. No other work had been performed between the recall and the onset of the leak. Our independent mechanic discovered physical damage to the original water pump consistent with a tool strike during the recall procedure. A new oem water pump was installed but failed immediately due to an underlying pressure issue originating underneath the intake manifold. The vehicle has been at vw of south charlotte since February 11, 2026 — seven weeks — with no root-cause diagnosis or repair. The dealership falsely documented oem parts as aftermarket, refused to diagnose the vehicle, and the service manager made his final decision based on text messages rather than any inspection. Vw customer care opened and closed six separate case numbers on this single unresolved complaint. Safety concern: the vehicle is non-operational and actively leaking coolant. The damage originated during a recall repair and has never been properly diagnosed or repaired. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

“brand-new 2026 vw Tiguan experienced sudden violent shaking, loss of power, and multiple warning lights within 24 hours of purchase. Dealer confirmed cylinder 1 misfire but could not identify root cause. Vw insists vehicle is safe to operate despite no explanation for failure. Vehicle is being returned without root-cause diagnosis. ”.

The 2021 Tiguan, r-line that I own now requires a new engine after roughly 70,000. The engine is no longer under warranty, according to the vw dealership, this is what is wrong with the engine - based on our observations and diagnostic review, we have determined that damage to the rotating assembly was caused by the presence of one or more metal objects entering the engine. This type of foreign-object intrusion can lead to significant internal impact, which is consistent with the damage we found during our assessment. Also, if you do a search on reddit and other public forums, there are a lot of 2021 vw Tiguan's with similar issues.

Problem description: 2022 Volkswagen Tiguan (VIN: [xxx] ) diagnosed with excessive oil consumption and coolant loss requiring cylinder head replacement. Vehicle at dealer since December 6, 2025, part on national backorder, estimated 6-7 more months wait (total downtime already ~1. 5 months). Dealer advised retrieving car tomorrow and driving it while monitoring/adding oil and coolant as needed. This is unsafe: low oil risks engine seizure, low coolant risks overheating—either can cause sudden failure, stalling, or power loss while driving, creating crash risk (especially with my child as frequent passenger). Symptoms: frequent low oil warnings, coolant loss, check engine light, white smoke from tailpipe. Appears linked to known ea888 engine issues in recent Tiguans (ongoing class action on oil consumption). Request NHTSA review as potential safety defect, including repair delays amplifying risk. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I’ve had my Volkswagen tiguen since 2021 fresh off the lot. I have been the only owner of the car at about 30,000 miles my head gasket blew, causing the engine to go into default after weeks in the dealer. They replaced the head gasket and stitched it up, the head gasket blew again at this point I was still under warranty so they agreed to replace the engine. It drove fine after the engine was replaced this year 2025. I started to have a whole host of problems. It began to jerk and hesitate at acceleration. My engine light came on with continuous jerking upon acceleration for weeks until I started to lose power in my engine. I couldn’t go over 50 60 mph. I would always pull the car over power it off and power it back on just to see if it would change and it didn’t do much I had a local mechanic add oil to each tire also drain the engine, which had shards of metal in it. And basically stitch the car back together until we can figure out the bigger issues. It’s only been a day since the oil was added to each tire. I had a very violent jerk of the engine, which made it feel and sound like I blew a tire I got out to look at the tire and it was just fine. It was the backfire of the engine going into the exhaust that caused such the violent jerk. Happy that no one was on the road. If somebody was behind me it would’ve easily been an accident. Most of these dealerships know exactly what’s going on and have been avoiding the big conversation of what to do next they rather just replace and band-aid these things into the consumer just gives up. I have two small children and this is the only means of transportation. I’m fearful that I’ll be stuck with a car note for a car. I can’t drive.

While driving 70mph on the interstate in the middle lane with an 18-wheeler next to me in the right lane, my can all of the sudden a warning for an over the 4000 max rpm and an epc light, which caused my car to start loosing speeding no matter how much or hard I pressed the gas peddle, in a matter of a minute my car dropped from 70 mph to 40mph and had to hit my flashers.

My car was less than a year old, had been at the dealership for routine maintenance on September 24th, and with no warning signals from the vehicle's electronics smoke started coming out from the hood while I was ~20 minutes into my drive to work. Within a short period of time there were flames, and ultimately the car was engulfed in flames, resulting in a total loss.

I had routine oil change. I picked up my car and immediately the red warning light came on. I called garage. They said it was pvc valve for high pressure. I fixed that. This is next routine oil change. Now the accessory bracket seal and oil cooler seal need to be repaired. My car only has 68,340k on it. I see there are many complaints on line about this issue.

Car has been consuming excessive oil in a short amount of time, Volkswagen claims it’s in “normal” specs but car consumes all the oil after oil change within 1200 miles. Between 0-5,000 miles 2 extra quarts will be added to engine. First time I noticed it was a month after purchasing the car when my oil/engine light came on. Recently oil cap blew off.

2021 Volkswagen Tiguan, approximately 40,000 miles?date of failure: oct 12th, 2025?component(s): engine, powertrain, vehicle speed control, throttle body description of the problem:?my 2021 Volkswagen Tiguan experienced a complete engine failure despite having multiple prior service visits for engine-related issues while it was still under warranty. During the warranty period, I brought the vehicle to grand junction Volkswagen (grand junction, CO) several times for problems including: * excessive oil consumption * “check coolant” warning light turning on * epc (engine power control) mode activating and loss of power the dealership performed an oil consumption test and told me the results were “normal,” but they did not address the coolant light or epc issues, stating these conditions were within normal limits. The same problems continued after each visit. At approximately 40,000 miles, the engine failed completely while driving, leaving the vehicle inoperable and creating a significant safety risk. The vehicle had to be towed. Volkswagen is now denying liability, claiming the vehicle is out of warranty, even though the same engine problems were documented repeatedly while it was still under warranty. I have opened a case with Volkswagen of America customer care (case #07085098), but there has been no resolution so far. Safety concern:?this issue poses a serious safety hazard. The vehicle can lose power suddenly and stall while in motion, which could lead to a crash or leave occupants stranded in unsafe conditions.

On 10/11/2025 while driving, the vehicle caught fire.

During normal operation on a public road, the 2024 Volkswagen Tiguan suddenly began emitting smoke from the front of the vehicle. This occurred without any warning lights, messages, unusual smells, or symptoms beforehand. Within moments, flames became visible from under the hood. The occupants, including a child and an elderly family member, immediately exited the vehicle. The fire spread rapidly and resulted in a total loss. The fire department arrived and extinguished the flames, and both fire and police reports were created documenting the incident. The vehicle was nearly new, with approximately 7,000 miles on it, no mechanical issues, and no prior maintenance warnings. Nothing unusual occurred during the drive, and the vehicle had been used under normal, paved-road conditions. On November 5, 2025, Volkswagen conducted an inspection at the iaa facility in puyallup, wa. Volkswagen later denied liability, stating that burned and unburned vegetation was found in the engine compartment and suggesting that external organic material may have caused the fire. This explanation appears unreasonable, as vegetation in the engine bay does not normally ignite spontaneously in a modern vehicle operating under standard conditions. The vehicle is currently with state farm at the iaa facility in puyallup, wa, and is available for further inspection by NHTSA if needed. This incident posed a serious safety risk to the occupants and to other motorists, and may reflect a potential safety defect requiring further investigation.

I am submitting this report to express serious concerns regarding my 2023 Volkswagen Tiguan, currently under a lease agreement and serviced exclusively at south motors Volkswagen in miami, florida. The vehicle was originally delivered as a loaner with approximately 1,000 miles and now has 24,000 miles. Since early in the lease, the car has repeatedly displayed low oil warnings, despite being serviced multiple times under 10,000 miles. During my most recent service visit in June 2025, I was charged $9. 48 for a minor oil top-off. When I contacted the service advisor afterward, I was advised to purchase 1-ow20 oil myself and manually add it whenever the warning appears, until the next 10,000-mile service interval. Following that advice, I have now purchased two bottles of oil out of pocket—the first cost $12, and the second $42—just to keep the vehicle running between service visits. This additional expense reinforces my concern about excessive oil consumption in a relatively new vehicle and may indicate a mechanical defect. Additionally, the brakes emit a persistent squealing noise, even though the dealership claims the brake pads are at 50% life. The noise affects driving confidence and may signal premature wear or improper installation. Despite these ongoing issues, no repairs have ever been performed under warranty. Each time I’ve taken the vehicle to Volkswagen service, I’ve been told that everything is functioning perfectly and that there is no problem to address. This repeated dismissal of the symptoms is concerning and leaves me without a clear resolution. My lease is scheduled to end in September 2026, but due to the unresolved mechanical concerns and the lack of meaningful support from the dealership, I would like Volkswagen to consider terminating the lease early. This would allow me to obtain a vehicle that does not present these recurring issues and restore my confidence in the brand’s commitment to safety and reliability.

I am reaching out regarding ongoing and escalating issues with my 2022 vw Tiguan r-line black. Over the past year, I have had to stop at jiffy lube multiple times because the oil level kept running low, and they repeatedly topped it off. I found this unusual, given how recently oil changes and services had been performed. This summer, the vehicle began experiencing episodes of stuttering and stalling, accompanied by smoke from the tailpipe. Over labor day weekend, after another stall, I brought the car into the vw dealership. They investigated but were unable to identify the cause. Unfortunately, the situation has now worsened. Today alone, the car stalled twice — both times in the middle of traffic. The “check oil level” warning light came on, followed shortly by the “check engine” light. There was also a significant amount of smoke coming from the tailpipe. This is not only a mechanical issue but also a serious safety concern. I have two children, and I am deeply concerned for their lives and safety when driving a vehicle that stalls unpredictably in traffic. At this point, the car feels unsafe and unreliable, and I am unsure how to proceed. Please advise me on next steps regarding potential legal recourse, warranty coverage, or claims I may pursue. Thank you for your guidance. Sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2024 Volkswagen Tiguan. The contact stated that while driving at an undisclosed speed, the low oil warning light illuminated, though the vehicle had previously been serviced within 1,600 miles. The vehicle was taken to an independent mechanic, who informed the contact that the engine had consumed four quarts of oil within 1,600 miles. The contact was advised to take the vehicle to the dealer for assistance. The vehicle was not repaired. The vehicle was taken to the dealer, who was unable to corroborate the independent mechanic's determination, instead finding that the vehicle was functioning normally. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 1,800.

I own a 2023 Volkswagen Tiguan (ea888 2. 0l). The check engine light has repeatedly illuminated, and multiple scans show recurring evap/emissions and network communication faults: p04f0 (evap purge line a performance) and p0451 (fuel tank pressure sensor range/performance), along with u1111 00 (“function limitation due to missing message”) and u1123 00 (“databus error value received”). While drivability may seem normal at times, these faults persist and clear/recur, raising concerns about fuel-vapor containment/emissions compliance and potential intermittent loss or limitation of vehicle electronic systems/driver-assistance functions due to can-bus communication errors. I’m reporting this because the condition is ongoing, produces a continual cel, and may present safety and reliability risks if not addressed by the manufacturer.

I purchased about 4 months ago with about 139,000 miles on it. The vehicle now has 142,000 miles and is experiencing excessive oil consumption—approximately 0. 9 quarts per 600 miles. Vw seems to be pushing this off and as I try to use my extended warranty I purchased when I got the car, aul has asked for an engine tear down. Vw knows about this issue, as it is internally a known issue for this model, yet they are unwilling to help. At time of purchase, this issue was not disclosed to me, as such had it been, I would not have chosen this car.

Check engine light came on and got estimate from pete moore vw dealer in pensacola, florida and was told the car needed extensive engine repair which included a new cylinder head part. So we waited to come get the car repaired on 3/5/2026 once we had saved up the money for it. We found out the cylinder head is on a nationwide back order with no estimated time to get it fixed properly. The technician who gave us the estimate back in September 2025 failed to mention that the cylinder head has been on a nationwide back order during that time. I am not the only person dealing with this issue in the USA but feel vw has not provided a fix or estimate time to repair these cars properly causing a safety hazard. This time to wait for a part is unacceptable and feel our cars fall under the lemon law.

I own a 2018 Volkswagen Tiguan with approximately 70,000 miles. The vehicle requires a full cylinder head replacement due to faulty valve seals. I have been having to add engine oil frequently between oil changes. The repair has been confirmed by an authorized Volkswagen dealership. The required cylinder head part is currently on manufacturer backorder with no estimated time of arrival. Dealership told me to check in every 2-3 months, as no additional cylinder heads can be ordered due to excessive backorder. Dealership charges $6,000+ for this repair. Volkswagen has not provided a solution or timeline for repair with this ongoing issue. There were no warning lights prior to the issue, and the vehicle has been routinely maintained. A major engine component failure at this mileage raises concerns about a potential defect rather than normal wear. This situation creates a safety and reliability concern, with no reasonable repair timeframe due to parts unavailability as well as no communication from Volkswagen regarding this ongoing issue.

My vehicle has relatively low miles on it, it does not get driven very often. Once I had done the first oil change I had to pay for after the dealer covered maintenance warranty was over for the oil changes was when I started having the problems. Three separate times the low oil light came on the dash and I had to add oil to my engine, about a total of 3 quartz. I told the first dealer that I was having this issue and they didn’t believe what I was saying and didn’t want to check anything. I told them to do an oil consumption test but because I had having such a hard time with them I went to a different dealer to get it look at. Under dealer warranty, they conducted the oil consumption test and after 600 miles I was to bring it back. When they did a volume displacement test, they said there was metal shaving in my oil when they went to drain the oil and they had to change the engine and turbo. My car was around 45,200 miles when it was said to be replaced. Ever since they said they replaced it the engine is very noisy, they didn’t put enough oil in the engine and it doesn’t even look like they replaced the engine at all. None of the hoses has signs that they were removed or replaced, bolts and nuts not removed and the transmission bolts don’t look they have been removed from the engine or got a new seal. This engine is not reliable at all. Also the vehicle certification label that should be in my wheel well and in my owners manual is not there. I can not find it anywhere.
