It appears that my Volkswagen Tiguan is experiencing an issue where the fuel nozzle shuts off prematurely during refueling, requiring multiple attempts to fill the tank completely. There have been no recalls on my vehicle, but it is getting to the point where I can barely fill my tank up due to prematurely shutting off. This has been an ongoing issue
Car exhaust is under car and does not come outside of under the car. We were in an accident and were told that because there are now cracks and gaps under the car that the exhaust is leaking into the body of our car and could cause co2 poisoning. If the exhaust were not under the car there wouldn’t be a safety concern
One of the fuel injectors cracked along with the fuel rail leading to a very large fuel leak. There was also an oil leak at the same time, but the origin has not been diagnosed. The vehicle was towed to the dealership to diagnose the problem and attempt repair. There were no warning lights, signs, or symptoms. I started the vehicle and drove approximately 20 ft to a stop sign, going under 10 mph, and all of a sudden smelled an extreme odor of gasoline. The check engine and other driver alerts came on.
