2023 Volkswagen Tiguan, approximately 34,316 miles. While driving on I-26 in South Carolina, the EPC warning and amber warning triangle illuminated. I pulled over and stopped. After approximately 10 minutes, I restarted because I was in an unsafe location. No warnings were displayed after restarting, but approximately five miles later they returned, and I exited the highway. After stopping, extensive engine oil was visible on the rear/underside of the vehicle. I immediately checked the dipstick and no oil was visible. At no time did I observe a low-oil-level or low-oil-pressure warning. An authorized Volkswagen dealer diagnosed a faulty oil separator causing internal engine pressure to build, which caused the oil pan to crack and upper timing cover to leak. The oil separator, oil pan and upper timing cover were replaced under warranty. During approximately two months before the failure, the vehicle had several times briefly displayed “Max engine speed: 3,000 rpm.” The night before the incident, the check-engine light illuminated but was no longer illuminated before the return trip began. The vehicle had received scheduled service, including an oil/filter change, at approximately 29,780 miles, only about 4,500 miles before this failure. My safety concern is the sudden pressure-related engine failure and major oil loss at highway speed, together with no observed oil warning despite no oil being visible on the dipstick immediately after the incident. The servicing dealer has stated that it does not know what causes these oil separators to fail. I am reporting this incident so NHTSA can evaluate whether it may represent a broader safety issue.

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.

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.

Driving long the interstate in South Carolina, all of a sudden there was a loud explosive sound and a crackling sound accompanied by the loud explosion. It startled me!! I gathered myself and put on hazard lights and got over on the far right lane to pull onto the shoulder of the highway. I thought that a tire or two had blown but was not the case. I got back into the car and started visually looking around to see where the crackling noise was still coming from. I looked up towards my Sunroof and discovered that a large hole in my Sunroof. Fortunately, my sunshade was closed and shield the debris/glass from spraying my face and body. I took the car to the V.W. dealership and explained the infraction to them. They diagnosed the problem and contacted me later that day to let me know that they were sending the request to V.W. corporate to get authorization to repair under warranty. The dealership did not detect any signs of rocks or debris causing the explosion. Corporate denied the dealerships request to repair under warranty. I filed the damaged Sunroof under my auto insurance. Im currently awaiting for the adjuster to inspect the damaged Sunroof that is at the dealership. I feel that Corporate dud not even consider the fact that this could have been an exploding Sunroof...and im sure that they have encountered this defect before. There are articles on-line of others who encountered this problem.
