The contact's fianc owned a 2020 Volkswagen Tiguan. The contact stated while his fianc was driving 30 mph when the steering wheel and the entire vehicle began to shake. The contact stated the Electronic Throttle Control warning light was illuminated. The driver was distracted by the failure, which caused her to run a red light and crash into another vehicle. All front and side air bags deployed. The driver did not sustain any injuries or seek medical attention. The contact stated his mother was seated at the rear driver side and did sustain injuries on both of her knees and sought medical attention on the day of the accident and also the following day. The contact stated unknown person in the other vehicle sustain also injuries on their knee. A police report was filed. The insurance company deemed the vehicle totaled. The vehicle was towed to the insurance lot. …
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 contact owns a 2020 Volkswagen Tiguan. The contact stated that while the outside temperature was cool, the vehicle operated normally. However, when the heat index was high, the message that the starter was hot was displayed. Shortly afterwards, the instrument cluster went black, and the vehicle stalled. The driver was able to coast the vehicle to the roadside. The contact waited approximately five minutes and restarted the vehicle. While driving in a subdivision, the vehicle stalled again. The local dealer was contacted, but there was no response despite the contact leaving a voicemail. The vehicle had not been diagnosed or repaired. The manufacturer had not been notified of the failure. The approximate failure mileage was 63,000.
The contact owns a 2022 Volkswagen Tiguan. The contact stated that while stopped at a traffic light on an extremely hot day, the message that the starter was hot was displayed and the vehicle shut off unexpectedly. On another occasion, while making a turn, the vehicle stalled and lost power. The contact was able to safely coast over to the emergency lane. After waiting for the engine to cool down, the vehicle was restarted. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 67,000.
The contact owns a 2020 Volkswagen Tiguan. The contact stated that after adding a quart of oil, the contact became aware that almost every three weeks there was blue smoke coming from the exhaust pipes. The contact stated that the oil warning light was illuminated. The vehicle was taken to an independent mechanic to be diagnosed, and it was determined that the engine was consuming an excessive amount of engine oil. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 68,000.
The crankcase breather valve (PCV system) on my 2020 Volkswagen Tiguan failed, which caused catastrophic engine damage. VW Southtown diagnosed the engine as condemned and stated that a full engine replacement is required. Prior to the engine being condemned, I have already spent $3,787.59 in repairs at VW Southtown addressing recurring oil-related issues caused by the PCV valve being stuck closed. This caused an excessive crankcase pressure buildup of over 0.5 psi, as documented on the VW service repair order. The failure occurred while my husband was driving our [redacted] son in the car, and the warning message immediately displayed on the dashboard was: "12V battery not charging. Stop engine." This sudden loss of engine function and dashboard warning posed a serious safety risk, as it could have resulted in loss of power or control while driving. …
I have been experiencing a noticeable delay in throttle response when accelerating, particularly when attempting to slowly merge into traffic. For example, when I press the accelerator to make a left turn, my Tiguan hesitates for approximately 2-3 seconds before responding, creating a significant safety concern as I find myself stuck in oncoming traffic. I took the vehicle to the dealership for diagnostic testing, but no fault codes were detected, and no warning lights were illuminated. To demonstrate the issue, I had to conduct a test drive with the mechanic. Following this, the mechanic escalated the issue to the quality engineering team at Volkswagen. They acknowledged that they were aware of this problem but stated that there is no available fix. I was advised to use top-tier premium fuel and switch to manual mode to potentially mitigate the delay. …
While driving my 2020 Volkswagen Tiguan (equipped with approximately 39,000 miles), the vehicle suffered a sudden and catastrophic total engine failure without prior warning, resulting in an immediate loss of power and propulsion while in motion. This sudden stall on an active roadway created a severe, immediate safety hazard and a high risk of a collision. The vehicle has been meticulously maintained with a complete and documented history of annual professional servicing. Prior to the failure, the engine repair light would frequently illuminate. Upon subsequent teardown and investigation of the failed engine, the authorized manufacturer dealership discovered heavy metal shavings in the engine oil, indicating severe and premature internal mechanical destruction of critical engine components. The vehicle has been diagnosed as requiring a complete engine replacement costing $9,000. …
I am reporting excessive engine oil consumption on my 2020 Volkswagen Tiguan. The vehicle consumes approximately one quart of oil per 1,000 miles. The vehicle has already undergone multiple diagnostic and repair attempts, including PCV-related repairs, all paid by the owner. Despite these repairs, the excessive oil consumption continues. Volkswagen and the dealership have stated that this level of oil consumption is "within range" and have required additional paid testing to further evaluate the issue, even though prior repairs failed to resolve it. I am concerned this reflects a broader engine design or component issue, as similar oil consumption problems have been widely reported by other Tiguan owners. I am submitting this complaint to document the issue and request further review. …
There is a major lag in acceleration. It happens randomly so taking to a dealership won't help because they will only try one time then say they can't reproduce the problem. From a stop or turning into a lane I can have the pedal to the floor and the car just stalls and doesn't go. After a few seconds the car finally gets a boost then goes. Well personally those seconds could lead to a car hitting me. I have asked my local dealership many times about it and they don't seem to care or want to look into a problem. The idea of a car is hit pedal and it goes but not the Tiguan. There is a known problem and this should be fixed. This has been going on since I purchased car. Just getting tired of this situation.
