Volkswagen Tiguan collision warning problems

Filed Oct 15, 2026 · Brakes, Driver assistance · TN

I am reporting a serious engine defect on my 2022 Volkswagen Tiguan at approximately 39,500 miles. The vehicle has excessive oil consumption and an oil leak. The authorized dealer diagnosed the problem as requiring full cylinder head replacement. This is a major engine repair at low mileage. I previously told the dealer the vehicle needed oil added between changes. The issue has worsened and now requires a cylinder head. I escalated with dealership management and Volkswagen Customer Care. Volkswagen refuses full coverage and offers only partial goodwill, leaving me to pay a large portion out of pocket despite the low mileage. This issue is widespread on 2022–2023 Tiguan models with the 2.0 TSI EA888 engine. Multiple owners report the same oil consumption and cylinder head replacement. Consumer Reports has documented cylinder head and oil consumption complaints on the 2022 Tiguan. Class action lawsuits allege a defect causing excessive oil consumption. The Canadian Automobile Protection Association has also reported premature valve guide wear leading to cylinder head replacement on 2018–2024 Tiguans. Excessive oil consumption creates a safety risk. Low oil can cause engine damage, stalling, or complete engine failure while driving. A vehicle needing frequent oil top-offs and a major internal repair under 40,000 miles indicates a possible manufacturing defect that Volkswagen has not addressed with a recall. I have also experienced issues with the forward collision warning system, the PCV valve, the infotainment system, and brake vibration when braking. These secondary problems further show reliability concerns, but the cylinder head failure is the most serious and safety-related issue. I request that the federal safety agency review this complaint with other similar reports and investigate whether a safety-related defect exists in the 2022–2023 Volkswagen Tiguan that requires further action or a recall. Vehicle: 2022 Volkswagen Tiguan Mileage: approximately 39,549 miles

This car has several issues and I could only select a few. Electrical: the infotainment system disconnects from Wireless car play at random when you drive the vehicle. It then returns a Wifi error on screen and you cannot use car play any longer on both android and iOS. Additionally, the electronic system will reboot when the car is in use. In my case, it always happens on the freeway when driving 75 MPH. The entire car dash is electronic, no buttons. So when this happens, you lose all safety features, have no idea what speed your driving, can't use the radio, navigation, air conditioning, etc. Most importantly, this is a deadly error WV knew about but sold the car anyways. The dealer and WV North America says this is a problem between the infotainment system manufacture and T-Mobile cell towers. There is no fix for it. So what are consumers to do? I paid cash for a product, the product does not work, the manufactuer cannot fix it. Normally when this happens the company either 1) fixes the problem for free or B) lets you return the product. VW says I can't do either. Backup Cam - the camera is cheap, blurry and picks up nonexistent items and slams on the breaks everytime I back down my driveway. Not a human, animal or event a tree limb blowing in the wind. However, when a car is behind you, the backup cam will let you back into the car. Again, this is a "Software" issue and the dealer cannot fix it. Forward collision Warning, Adaptive Cruise Control, Blind Spot Warning, Lane Departure Warning and Lane Keeping Assistance only work intermittently. I'd say about 30% of the time I drive the car, it just dings at me while my dashboard lights up and says all these features failed. VW has no record of it in the cars "error log" so I had to set up a camera in my car to prove them wrong. Once they saw it, they said they don't know a fix. Maybe they can swap out the infotainment system / software, but that requires several layers of approval first.

The adaptive cruise control (ACC), forward collision warning, and automatic emergency braking/front assist systems have repeatedly malfunctioned. The vehicle has been returned to the dealership multiple times for diagnosis and repair, but the issues remain unresolved. These are safety systems designed to help prevent or mitigate collisions. When the adaptive cruise control and automatic emergency braking systems become unavailable or fail to function properly, I cannot rely on features intended to assist in maintaining safety. The loss of these systems creates a potential safety risk for me, my passengers, and other motorists. The vehicle has been presented to an authorized Volkswagen dealer on multiple occasions for these concerns. The dealer has attempted repairs, but the problems continue to occur. Warning messages indicating that adaptive cruise control, front assist, or automatic emergency braking systems were unavailable appeared before and during the malfunction. I thought before they were just faulty sensors. The dealer never explained these features were not functioning. The symptoms first appeared while the vehicle was under warranty and have continued despite multiple repair attempts. The car was purchased brand new from the dealer.

I purchased this vehicle on August 9th 2025 and it has been in shop 4 times . It is in the shop as I am writing this email. I have had nothing but issues with this vehicle and had to come out of pocket 308 dollars just to find out a problem that I told them that already was an issue the first week I had the car . I am a senior on a fixed income and I cant afford to pay anything more out of pocket . I filed a complaint with the BBB and a represented from the service department called me and said , his boss said they will not work on my car unless I remove my complaint to the BBB . I find this very unethical and a bad customer service representation. This car has been diagnosed unsafe to drive . And even though I have a loaner it is not my car I am paying for . Like I had stated it has been in the shop 4 times and I have not missed a payment even though I have not had my car .The front strut is completely broke , the left one is in bad shape , needs a front end alignment and the front collision warning alert does not work . It has been confirmed these issues are there. They said they were going to take care of it until they noticed I filed a complaint to the BBB.

While driving south bound on i95 express lane, the vehicle in front of me stopped abruptly. I attempted to break but was unable to do so. Also the emergency breaks/front vehicle collision warning did not activate. In order to avoid a head on collision, I swerved to the right and my front left side made impact to the other vehicle on their right back side. This impact cause my vehicle to spin out of the express lane and into the regular traffic 180 degrees causing me to be facing incoming traffic. The air bags did not deploy- the state trooper, fire safety, and tow truck representative all commented that it should have. After the incident FDOT had to tow my vehicle to the shoulder prior to being towed away. During this time I was not able to turn the engine off- it remained on and was towed with the engine still running. The vehicle is currently under assessment with my insurance provider.

Travel assist goes on and off at random times . The wipers turn on and off by themselves. Also the front collision warning light comes on randomly.. what should I be doing with this vehicle… I’ve read many reviews that other people have the same issues.

Twice now I’ve been driving with no vehicles or anything in front or even behind me & the big red collision warning comes on & the brakes activate.

I was driving down a completely clear road, not a single car or turn in sight. When suddenly my cars front collision warning comes on the screen and brakes my car for me. There was no advance warning, just hard braking.
