Engine And Engine Cooling problem #1

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.

Engine And Engine Cooling problem #2

This vehicle is unsafe for two reasons. First, it slams you on brakes and puts you in park at random times. Middle of road, parking lots, etc. This puts you at higher risk of someone hitting you. The second thing is when pressing the gas when taking off after a stop, the rpm’s jump up and the engine revs up, but the car is barely going. Not safe when crossing intersections along with many other times. Both of these puts mine and my families safety at risk along with others on the road. No warning signs, lights, etc. Car is in shop for second time. First time on November 28, second time on December the 11. Still no answer on a fix. Just that they think they may know the cause. The dealer has gotten the car to reproduce these issues.

Engine And Engine Cooling problem #3

The contact owns a 2026 Chevrolet Traverse. The contact stated that while driving at 35 mph, the check engine warning light illuminated. The vehicle was taken to the residence. The contact stated that while making a right turn into the dealer to have the vehicle diagnosed, the brake warning light illuminated. The vehicle was diagnosed, and determined that the brake master cylinder needed to be replaced. The vehicle was not repaired because parts were on back order. The manufacturer was notified of the failure. The failure mileage was 500.

Engine And Engine Cooling problem #4

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.
