I was driving the vehicle and without warning it just stopped shut off and immediately shot an error code that there was a critical issue with the engine and that the oil pressure was low, and the vehicle would not start and was not drivable. It had to be towed to a dealership.

Transmission malfunction. This has appeared several times at highway speeds and low speeds. We have dad to limp along in the slow lane to exit ramp and take back roads to the nearest dealership. The current problem has been confirmed with error codes P0747. The dealership has scanned this vehicle and detected error codes in the past on two different occasions and found P176C in TCM on 08/01/23 and P17D6 on 10/24/24. Check engine light comes on with a screen prompt “Reduced Acceleration Drive with Care”. The transmission valve body has already been addressed once because of triggering limp mode.

This vehicle shifts hard and was identified to have a transmission valve issue. It should be under the same recall that other Chevrolet vehicles have with same issue. On top of this, Chevrolet cannot keep up with demand for this part making only 500 per week. I’ve been told it may be 2 months before I have my vehicle back.

Check engine light came on Then : message saying power reduced. Then: Service transmission, unable to shift soon. While driving on the highway. Vehicle has been at dealership for a month with no idea on when parts will be available. They say they have no idea on when a valve body part will be available.

6.2L L87 Engine Failure with 36,000 miles on it. While driving on the highway and attempting to pass another vehicle that was traveling on a 2-lane highway the car suddenly died, and the transmission shifted into neutral. When I noticed the vehicle would not accelerate, I looked down and saw the push to start warning and tried to restart the vehicle with no response. I had to allow the vehicle I was passing to get ahead of me before I could swap back into that lane to get out of the way of oncoming traffic eventually coasting onto the side of the road to a complete stop. The vehicle I was passing slowed down after the engine died not knowing what I was doing and drove right beside me blocking the lane until I signaled for them to go ahead so I could get back into the lane. If the vehicle in the oncoming lane had not slowed down to allow me time to get back into the proper lane a head on collision would have occurred. This 2023 vehicle was purchased used 14days prior from a GM certified dealership and had no warning lamps on the dash and showed no indication a failure was about to occur. The vehicle was driving perfectly normal until the failure occurred. Once the vehicle was towed to the dealership it was determined the engine had failed due to crankshaft bearings. The dealership explained there were no available replacement GM engines and could possibly be a lead time of 6 months before a replacement engine could arrive. I purchased the vehicle for $60,000 and the engine fails 14 days later and now I could be without a vehicle for 6 months and the dealership did not have any loaner vehicles available.

Driving the vehicle on an interstate highway with the flow of traffic at 70 mph, without warning the engine shut off. This caused loss of speed and loss of power steering, almost causing me to be hit in the rear end twice at highway speeds. There were no warning lights or any instrument indication prior to the failure. After barely being able to get the vehicle into the brakedown lane, the vehicle would not restart. The electronics all worked, there were no warnings or indicator lights but the engine would not start despite multiple attempts by myself and the tow truck driver. The vehicle is currently at the dealership being diagnosed.
