| Engine And Engine Cooling problems |
While driving at road speed, the vehicle unexpectedly shifted itself into neutral (n) without driver input. The engine continued running, but the vehicle lost drive power. Simultaneously, the dashboard displayed multiple warning indicators including: “exhaust system malfunction” warning semi-automated driving assistance warning sos / emergency system warning the driver safely pulled to the roadside and turned the vehicle off. Upon first restart, the vehicle would not shift into drive. After turning the vehicle off again and waiting approximately 30 seconds, it restarted and allowed drive engagement. The “exhaust system malfunction” warning remained illuminated for the remainder of the trip. The vehicle was taken to a Volkswagen dealer. The dealer was unable to duplicate the condition after a 50-mile drive. Dealer reported only a rear radar fault code and stated no other diagnostic trouble codes were stored. Warning lights had cleared by the time of inspection. This was an unintended transmission disengagement event while in motion. The loss of drive power at speed presents a safety hazard. The vehicle is a 2025 Volkswagen Tiguan built mid-2025 and currently has approximately 1000 miles.
Since buying the car in August 2025, I've had multiple issues. Ive had a noise coming from the front passenger side of the vehicle, brought it in and they could not identify the issue or fix it, to this day I still have this noise coming from the front passenger side. Furthermore, I've had numerous hazard lights come on the dash, lasting 2-4 days and then disappearing and reappearing later on. These lights include the check engine light, oil leaks, and not allowing the car to drive over a certain limit due to engine issues. I've also brought these issues to the service center so they can diagnose and fix the issue. They are unable to find anything wrong. Most dangerous event is the car completely shut down on me while driving. This is extremely dangerous to not only myself but others around me. I brought this concern to the service center and they could not figure out why this happened. This car is unsafe to drive.
I was at a complete stop at the red light, vehicle began shaking and shut down. Gears would not work therefore I was not able to put it in neutral to at least push out of the road. The vehicle then began cranking on and off on its own, without me pushing start/stop engine. This was completely unexpected as the truck is one week old, had a full tank of gas and it was especially dangerous to have shut down on a busy highway. Also when reversing the vehicle makes a weird click noise.
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.
Engine stumbles repeatedly, stutters and dies. No warning lamps. Car inspected twice by manufacture but no solution found. Continues to show same characteristics. Have to pull off the road to avoid danger to self and other autos.
