Owner complaint summary
The vehicle exhibits unintended acceleration behavior when the brake pedal is applied. Instead of slowing down, the engine revs and the vehicle does not decelerate as expected. On March 16, 2026, while merging onto a highway and applying the brakes, the engine suddenly revved to approximately 3,500 RPMs while the vehicle failed to slow down. There have been previous issues with the vehicle not slowing when breaks are being applied, nut this is the first instance when it was noticed that the RPMs increased while breaking. This issue has also been reported to the dealership, with service documentation noting that when applying the brakes, the engine revs and the vehicle does not slow or accelerate properly. This creates a dangerous condition where braking input does not result in expected deceleration and may instead cause acceleration-related behavior. The issue has not been resolved. This issue significantly increases the risk of collision and loss of vehicle control.
