2026 Chevrolet Traverse Engine Problems

“Purchased the car in August 2025 and have had into service 3 years for the same issues. When driving the car, the RPM will get stuck between 5-6 when only driving 20-30 mph. Once I slow down/brake, it will jump into a park effect, but still be in drive. The car has been inspected by Chevy 3 times, but they can't get any fault code on the vehicle, so they can't fix the issue. This puts myself and my small children at risk because if it jumps into the park effect, while still in drive, I can not move and someone could rear-end me. I do have video evidence.”

“The contact owns a 2026 Chevrolet Traverse. The contact’s wife stated that while driving 55 MPH, the electronic control system and brake system failure the vehicle decelerated and went into LIMP Mode. The brake pedal became spongy, and while driving, the vehicle coasted to a stop. The vehicle was shifted into park(P), turned off, restarted, and the vehicle operated normally. The failure had reoccurred twice. The contact scheduled an appointment with the dealer. The failure mileage was approximately 4,900.”

“While driving 65mph, the vehicle’s engine shut off, a ‘Reduced Acceleration Drive with Care’ message showed up and I had to coast to the side of the freeway. Engine would not restart and dealer confirmed a piston contacted a valve and a new engine is needed.”
