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!

I had noticed an intermittent chirping noise coming from the vehicle, but no warning lights were on and it did not seem significant, I thought maybe it was a squeaky belt that I would have checked at our next routine maintenance. My husband drove the vehicle next for an approximately 12-mile round trip. He noticed the noise get more consistent and louder, and while pulling into our driveway, I observed that the sound was very loud and smoke was coming from the right side wheel well. As soon as he put the vehicle in park, coolant flooded the driveway. We had an independent mechanic come to our home to diagnose the vehicle. He stated that the water pump completely blew and the pulley was loose. The mechanic emphasized that a car this age should not have had a loose water pump/pulley and that this was a manufacturing issue. He was very concerned that if it had blown while driving, it would have shut off the engine entirely and could have caused a catastrophic accident. He recommended a new water pump and thermostat.

The vehicle began to shake as if it would shut down. Then, the engine light came on. Then I received three text message alerts. We were shown paperwork regarding the service history that was done at Philips Chevrolet. Now we-€™re getting alerts regarding work that has to be completed within 7 days.

I purchased this vehicle in Dec of 2019 used. 35,000 miles. Now has 88,000 and the transmission went out. Regular oil changes. No warning lights. No issues. Stopped running. After having someone look at it to see what the issue was, the mechanic said the entire transmission has to either be rebuilt or replaced.
