Hello, To whom it may concern, My vehicle is a 2018 Chevy Suburban with a 5.3 motor. GM produced these motors made from inferior metal and defective lifters. My engine began failing in May 2022, I've taking my vehicle to several shops for work but the problem has not been resolved. I have links below explaining the problems with these motors. There are tens of thousands of individuals with families struggle with this same problem I'm having as well. This is world wide news, I'm asking for help for myself and so many other people in these challenging times. I've contacted GM headquarters. [XXX] and [XXX] with no success, just the run around. I went to a GMC dealer here in Clarksville, TN where I reside this month. [XXX] with GMC told me he was hearing my lifters and I need not drive my vehicle. Called me in his office and told me he couldn't get my vehicle in to be looked at, but gave me another dealership contact information. I called and spoke with a gentleman by the name of [XXX] he also informed me that they were backed up and couldn't see me until October 5th. All warning lights came on in May of 2022, engine and steering and traction. Please view these links below that explain in further detail. Thank you for your time and help!

Suburban 8-cyl

  • 18,000 miles
I drive a 2018 Chevy Suburban. This car had no lights on and has less than 18K miles on it. It is just over two years old and there are no recalls on the vehicle. I was driving with my [xxx] child and we had driven about a mile. We were on the feeder road about to get on the freeway. The car started spontaneously accelerating on its own. Jerking faster and faster without me touching the gas. It was like we were on a runaway train. I panicked and slammed my foot on the breaks. There were no breaks - no tension or pressure in the brake pedal. The pedal just continuously slammed into the bottom of the car. I couldn't stop us. I thought quickly and slammed my foot on the parking brake as our car continued to accelerate quickly with no brake function. We jolted to a stop as cars zoomed around us honking and yelling. When I took the car off of the parking break, the same problem continued. No breaks and sporadic acceleration. Immediately after this incident a light came on that said 'service stabilitrak'. the car was towed to the dealership. I'm sharing this for all car owners to remember the power of your parking break in an emergency. It's one thing to be annoyed when your car won't go, but it is pure panic and fear when your car won't stop and keeps going faster - especially with your precious child in the back seat.

The stability track lights keeps coming on and off. Dealer can't seem to find out what the problem is. It does not leave a code in order to find out what the problem is. When the light comes on it affects the cruise control and steering assist. This occurs while driving the vehicle. It doesn't matter if you are on a city street or highway.
