2024 Volkswagen Tiguan Transmission and drivetrain Problems

“Our vehicle does not respond to the throttle pedal being depressed when the AC has been turned on at full and the car has been in direct sunlight for a period of time. We reside in Florida so it is common to enter the vehicle during the summer months and the cabin temperatue is in excess of 200 degrees which requires putting the AC system on MAX. This problem occurs periodically and was address in the summer of 2025 at the VW dealership locally”

“I am filing a safety complaint regarding a serious transmission defect in my vehicle. The drive and reverse gears are not functioning properly. After driving for a few minutes and parking, when I attempt to reverse on an inclined surface, the vehicle unexpectedly moves forward instead of backward. Similarly, when the vehicle is parked facing downhill and I shift into drive to move forward, it rolls backward. There are no warning lights or dashboard indicators alerting me to any malfunction. Due to this defect, I have nearly collided with objects multiple times within just 15 days of ownership. …”

“Catastrophic loss of throttle response and severe acceleration lag from a standstill under high ambient temperatures, presenting an immediate collision hazard. On more than ten (10) separate occasions, the acceleration on this vehicle from a complete standstill has unexpectedly dropped to a dangerous level, performing at or below the speed and power of an un-indicated limp mode. This hazardous condition is explicitly triggered by ambient heat: it frequently occurs in temperatures above 90°F and consistently occurs when temperatures exceed 95°F. …”

“The vehicle experiences sudden loss of motive power during acceleration. Between 30–60 mph, the transmission fails to upshift correctly, causing the engine RPMs to spike to 5000 while the vehicle fails to gain speed. This creates a severe safety hazard when merging into high-speed traffic. Additionally, the infotainment system frequently blackouts and reboots while driving, and there are intermittent malfunctions with the power windows and door locks. Authorized dealerships have been unable to resolve these persistent safety defects after multiple repair attempts.”
