Engine And Engine Cooling Problems of Volkswagen Tiguan - part 1

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.

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.

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.

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.

Epc light is on.

This stalling issue has occurred three times so far, most recently on [xxx], while exiting [xxx] . Each time, the stall happens when I attempt to accelerate after coming to a complete stop in traffic, at a light, or at a stop sign. When it occurs, the vehicle will not move forward, and multiple rapid warning messages appear on the dashboard. The only way to recover is to shift into park, power the car off, and then restart the engine. After restarting, the vehicle will usually operate normally, allowing me to continue driving. I brought to vw dealership pasadena -- they have been unable to diagnose the cause of stalling! text from dealership below! this happened exiting the freeway this is very dangerous. +1 (818) 293-1855: we cleared all codes and going to give the car back to you for now-the recall adhesive needs to cure till end of the day-pick up at 4pm --ron hancock Volkswagen pasadena +1 (818) 293-1855: no-will have a plan of action and we can discuss --ron hancock Volkswagen pasadena information redacted pursuant to the freedom of information act (foia), 5 u.

Upon starting my 2021 Volkswagen Tiguan, the vehicle immediately went into "limp" mode and the check engine light and epc light came on. The vehicle would not drive over 18 mph. The car was towed to a close by Volkswagen dealership and checked for codes using a multipoint inspection. The report came back with a throttle body issue (multipoint inspection report attached). The throttle body was replaced and the vehicle was taken for a 15 mile test drive. During the drive, the same problem occurred. After the drive, 34 codes were found in vws report. I have also attached the report to this complaint. The technicians at the vw dealership didn't understand the problem, so they opened up communication with Volkswagen in germany. The Volkswagen engineer advised the dealership to replace the wire harness. After the wire harness was replaced, the car has no more issue (although it has only been 5 days since), which cost $2314. 54 in total. There is a class action lawsuit in the state of new jersey (case [xxx]) against Volkswagen group of America that states "vw is aware of concerns involving faulty wire harnesses". . . Affecting 2019-2022 Volkswagen atlas, golf, jetta, Tiguan, and taos. Thank god that this happened to my vehicle with the car was at rest and not traveling at a high rate of speed that could have been fatal.

The contact owns a 2022 Volkswagen Tiguan. The contact stated that after an oil change, additional oil needed to be added to the engine. The oil light was illuminated. The contact stated that when the brake pedal was depressed, the vehicle was slow to respond. The vehicle was taken to the local dealer, who was unable to determine the cause of the failure. The vehicle was eventually diagnosed and determined that the oil was leaking into the valve. The vehicle was repaired, but the failure recurred. While driving at an undisclosed speed, the vehicle began to smoke and then stalled. The brake lines were flushed. The contact had an altercation with the dealer and was banned from the location. The manufacturer was contacted, and opened a case but declined a buyback. There was no additional communication. The failure mileage was approximately 10,000.

My vehicle has a known manufacturing defect issue that has already been addressed in a Volkswagen technical service bulletin (TSB) which results in an oil consumption issue with 2022 and 2023 Volkswagen Tiguan models. Vehicle problem was confirmed and repaired once by dealership however same oil consumption issue has happened again that was confirmed by dealership. Dealership presently is unable to repair because necessary replacement parts are unavailable at this time.

The contact owns a 2021 Volkswagen Tiguan. The contact stated that while driving approximately 55 mph, the check engine warning light illuminated. The vehicle was not diagnosed or repaired. The contact stated that on three separate occasions, while the vehicle was parked, the contact observed oil on the ground underneath the vehicle. The vehicle was then taken to a dealer, and oil was discovered under the vehicle. The vehicle was diagnosed, and determined that the breather failure caused the crank case pressure to enter the system, causing the upper timing gasket and seal to be compromised and leak oil. The contact was informed that the oil separator timing cover, cam magnets, and oil pan needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was approximately 50,000.

My 22 Volkswagen Tiguan could very well be apart of the class action lawsuit that is happening right now with oil consumption issues my vehicle only has 45,000 miles and is consuming 1 quart of oil every 1200 miles started noticing oil loss back in July.

I am experiencing a serious safety issue with my 2022 Volkswagen Tiguan involving delayed acceleration. The problem occurs intermittently but frequently: when pressing the gas pedal from a complete stop or low-speed situation (such as turning or merging), there is often a 5–10 second delay before the vehicle responds and begins accelerating. During this lag, the engine does not rev, and the vehicle does not move, leaving me and my passengers vulnerable in intersections, while turning into traffic, or merging onto highways. This issue has occurred multiple times since purchase, and has created multiple near-miss situations, including once where I attempted to cross a two-lane road and the vehicle did not move for several seconds after pressing the accelerator. Other drivers had to brake abruptly to avoid collision. I brought the vehicle to an authorized Volkswagen dealer twice. They were unable to replicate the issue and returned the car without repair. The third visit is currently being scheduled. No warning lights or diagnostic codes were present, and the dealer stated they could not reproduce the problem. Volkswagen has not issued a fix to my knowledge. The vehicle has not been inspected by police or insurance. There were no warning lamps or messages at the time of the failures. The issue began within the first few months of ownership and has persisted intermittently for the past several months. I paid $30,000 cash for this vehicle in 2023 and it is still under warranty. This issue presents an ongoing safety hazard and significantly reduces my confidence in the vehicle’s ability to respond in traffic. Based on forums and consumer reports, I have reason to believe this is a known issue affecting multiple vw Tiguan vehicles of the same model year. I am available to provide additional documentation, including a written log of the issue and video evidence upon request. I respectfully urge NHTSA to investigate this matter.

Excessive oil consumption: I purchased this Tiguan 2022 back on [xxx] in florida and since I purchased it I have issues with this matter. I have reported my Tiguans consuming oil at a rate significantly higher than what's expected between oil changes and I was informed that is normal, yet I still did not get any resolution on this matter. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact's granddaughter owns a 2023 Volkswagen Tiguan. The contact stated that while her granddaughter was driving at an undisclosed speed, the low oil pressure warning light illuminated. The vehicle was driven to the residence, where oil was added to the vehicle. The vehicle was then taken to the dealer, where an oil change was performed. Additionally, the dealer replaced the oil separator and gasket. The vehicle was repaired. The manufacturer was notified of the failure and informed the contact that the repair could not be covered because the vehicle was out of warranty and the previous oil changes were not performed by the dealer. The failure mileage was approximately 66,000.

This vehicle has burned oil and needed regular additional oil fills between recommended oil change. We have taken the car to Volkswagen northampton for regular oil changes who have never dealt with the oil leak or burning issue. As a result of this the car now at 64k miles needs a new engine. It has piston issues , timing belt issues, , communication modules between the eco and bmc issues, and cam shaft timing issues. Our mechanic is suggesting a new engine. Vw of America will not assist us saying there is nothing they can do.

I am experiencing a high oil consumption rate on my 2023 vw Tiguan. Vw claims that the rate of consumption is within the 1 quart every 1200 miles limit, but 3500 miles after an oil change, the check engine oil light came on and I had to add oil. 2000 miles later, it came on again and I had to add oil again. In a 10,000 mile oil change rated car, this would equate to adding 8-9 quarts of oil between changes. This is not normal oil consumption. The effects of increased emissions and premature fouling of the catalytic converter system alone is cause for concern, or the possible loss of engine power on the highway due to failure from lubrication loss, resulting in an accident. The car will emit blue/white smoke from tailpipe and rough idle randomly when the cylinders are overloaded with oil.

My Volkswagen Tiguan suddenly and without warning blew a large amount of smoke out of the exhaust along with oil while driving at highway speeds - causing the cars behind me to lose visibility and possibly be covered with oil further reducing their visibility due to the vw manufacturers faulty crankcase breather/pcv valve. After this happened the car dash lit up with warnings and went into "limp mode" where I was not able to exceed 2500 rpm which is very dangerous when on the highway - luckily for my safety at this point I was on a side road. When I checked the engine I found no oil was left in it, it had been sprayed all underneath and up the back, which reduced visibility in the window. I was responsible for towing it to the dealer and was given no loaner despite being under warranty. Leaving myself and children without a vehicle. The dealer confirmed that my vw Tiguan had a faulty crankcase breather which caused over pressurization and pushed up the valve seals and cracked the oil pan. They only replaced those things and not the fouled spark plugs or oil filter from the crankcase breather failure which can cause more engine damage and dirty emissions.

The contact owns a 2022 Volkswagen Tiguan. The contact stated that while driving on a highway at 60 mph when the vehicle experienced a reduction in automotive power and the vehicle speed was reduced to 25 mph, the epc, check engine and master warning light. The local dealer was contacted however the vehicle was not diagnosed as the vehicles VIN was not included in any open recalls. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 58,000.

At only 38,200 miles the dealership found shards of metal in my engine. The only solution is to replace the entire engine and my car just passed its warranty 5 months ago. I have kept up to date with services and driven the car responsibly. There is also another 2021 vw Tiguan owner in my town and her car did the same thing at only 29,000 miles! she was still under warranty so the engine was replaced but she now states that it burns through oil at a concerning rate. One day the engine like just turned on, then the car goes into a “limp” mode and doesn’t exceed 3000rpm.

My car has delayed acceleration issues of between 3 - 6 seconds. The last one that was 6 seconds ore more was on June 29. In addition it's happened several times. I took the vehicle in for its last service and was told the issue was my battery. Battery was replaced and issue not resolved. The service before that I was told it was a carbon build up. Continues to happen sporadically.

Water pump leak/failure.

High oil consumption.

Low engine oil light appeared after 1000 miles. Car was topped off with oil and light appeared again. Oil consumption test was conducted car is burning 4. 5 q per 1000 miles, results have not been consistent. Vw claims this test is within their parameters but the car can longer travel 1000 miles until an oil change. More symptoms have appeared such as a decent size smoke cloud on engine startup. Both Volkswagen dealerships have said this is not normal to a new car and said you should contact customer service. It’s been 2 weeks and they have yet to respond.

The vehicle experiences intermittent (but daily) accelerator lag or failure to respond when the gas pedal is pressed from a stop. There is a significant delay—sometimes several seconds—before the car begins to move, even when the accelerator is fully depressed. This appears to be related to the power train and/or engine system. The hesitation in acceleration has created multiple unsafe situations, including near-miss accidents while turning left across traffic or entering intersections, when the car failed to respond as expected. This hesitation could easily result in a collision, particularly in high-traffic areas. The issue has been reported to the dealership on multiple occasions and while they have been able to reproduce the problem, it isn't every time and they turn the vehicle back over to us unresolved. Video documentation of the malfunction has been submitted to the service department, and they have acknowledged the issue is being reviewed by vw engineers. The vehicle has been inspected multiple times by the authorized Volkswagen dealership service department. Engineers from the manufacturer have reportedly been involved in the review, though we have not yet received a confirmed diagnosis. There are no warning lamps, dashboard messages, or error indicators associated with the accelerator issue. The first noticeable delay in acceleration from a stop occurred at least 6 months ago and has continued intermittently since.

To whom it may concern: I wish to report what a believe is a defect in the new Tiguan which is causing the engine to overheat. The check engine light came on the day after we purchased the vehicle. This was due to a part of the lower shutter in the front of the car breaking off, which prohibited the shutter from opening and shutting. It could not cool the engine and thus the engine started to overheat. We are not entirely sure what caused the piece to break, the mechanic said it was likely a rock. We did not get into an accident and in fact had only driven the car once. So I wanted to make this report in case someone else had a similar issue as if this piece is prone to breaking, it could potentially cause other more serious issues.

Timing chain and engine issues and repairs.

My vehicle will have a slow start when I start the car and also a delay when it is at a stoplight. I took it in for service twice and they told me it was because I had an after market battery. However - yesterday my car completely went dead at a stop light and I had to turn the engine off and in. It often lags or stops at a light. According to reddit it seems it’s a crank start issue.

The contact owns a 2021 Volkswagen Tiguan. The contact stated while driving at an undisclosed speed, the contact noticed blue smoke coming out of the exhaust pipe. There was no warning light illuminated. Additionally, the contact stated that the vehicle was experiencing excessive oil consumption. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 46,000.

The lower oil pan cracked due to excess pressure in the engine from a broken oil air vent. This is a very common issue in vw tiquans, that vw knows about but doesn't recall. The faulty air oil vent leads to cracked lower oil pans and oil dumps that can damgae the engine and creates dangerous driving situations.

Timing chain repairs and replacement.

Extreme oil consumption would cause a catastrophic engine failure. Low oil warning light going off (3 times within 3000 miles) requiring the need to add oil. Oil on dipstick is down to the bottom. Had local big o check it out - oil had been lost. Currently doing a 1000 mile oil consumption test through dealer. Started at around 48,000 miles. Currently have 52,000.
