2025 Volkswagen Tiguan

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.

I own a 2025 Volkswagen Tiguan SE R-Line purchased new in August 2025. Since shortly after purchase, the vehicle has exhibited a recurring safety defect where the electronic parking brake engages without driver input and the vehicle shifts itself into Park. This happens suddenly and without warning. This defect occurs multiple times per week, on average (upwards of 50+ times total since purchase) under varied low-speed conditions, including at stoplights, while slowly moving through traffic, and during parking maneuvers, etc. When it occurs, the vehicle stops abruptly as Park is engaged. This creates a significant risk of being rear-ended or losing control in an intersection or traffic lane. There are no warning lights, chimes, or alerts beforehand. The behavior is intermittent and unpredictable, so there is no way to anticipate or prevent it during normal driving. This has not yet caused a collision, but there have been near-miss situations in traffic due to the sudden stop. I notified the dealership when the vehicle was new, but because the model had only recently been released and the defect could not be reproduced on demand, there was no formal inspection or repair, and no guidance was provided. The issue has continued multiple times per week since then. I have now found other 2025 Tiguan owners reporting the same behavior, which suggests this may be a broader safety defect rather than an isolated case. I am requesting an investigation due to the frequency of occurrence and the clear collision risk associated with unintended braking and shifting into Park.

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.

Started noticing issues within first week of purchase. Cruise control will not increase nor decrease speed when set. Steering wheel controls will not advance or decrease speed. Intermittent problem. First service dealer could not replicate. Second service dealer contacted VW assist and was advised to replace steering wheel buttons. Did not fix problem. Third service VW assist advised to replace clock spring and wiring harness. Part still on back order almost a month later. Meanwhile, vehicle now rapidly decreases or advances speed on own while cruise control is set. Adaptive control function is off and not source of issue. I feel this is software related issue as I have also had malfunction of infotainment radio system. Another reason I feel software issue is due to vehicle back up safety braking activates and throws vehicle into park when nothing is behind me.
