2020 Chevrolet Suburban

Driving on the highway and I started to slow down even while pressing the accelerator. Pulled over and turned the car off and then back on. I was able to almost get to an exit but then it completely stopped moving. Turned it off and on again but car would not move. Not a single light turned on until the last time I attempted to move the car. Had it towed to Chevy dealer and transmission was completely out. Had 2 different mechanic places (dealer and private) tell me that it is extremely common once a 2020 suburban hits around 100k miles. That is completely irresponsible of GM to not put something out so that owners can at least have knowledge that there could be a potential problem. No warning signs, no lights on that is an accident waiting to happen and a potential wrongful death lawsuit coming your way if something isn’t put out.

Out of the blue, while driving, my car started lurching and making a weird rattling noise. I was able to make it to a mechanic, where I learned the cylinder lifters collapsed and crankshaft were broken. The mechanic told me this is a common defect for GM motors. My vehicle is only five years old, so to learn we have a $10-20,000 repair on our hands was paralyzing and devastating.

The contact owns a 2020 Chevrolet Suburban. The contact stated while driving 10 MPH and depressing the accelerator pedal, the vehicle failed to respond as needed. No warning lights were illuminated. The contact pulled over and turned off and restarted the vehicle however, the failure persisted. The contact stated that the dealer was contacted. The vehicle was towed to a dealer and was diagnosed with transmission failure. The contact was informed that the transmission needed to be replaced. The vehicle was not repaired. The VIN was not included in NHTSA Campaign Number: 24V797000 (POWER TRAIN). The manufacturer was notified of the failure but offered no assistance. The failure mileage was 93,000.

On October 27, coming back from a family trip at 10 PM at night on a major highway, the suburban all of a sudden quit. Traveling at 70 miles per hour, all of a sudden, when pressing the gas pedal, the car would not accelerate and the RPM gauge was erratically moving. The car started to slow down till it eventually just quit and it would not go anymore. We were stranded in the middle of the highway with cars coming and going both ways. It was scary, it was dark, and dangerous. A tow truck was called and they told the suburban to a Chevrolet dealership 60 miles away. The following day, the dealership informed us that the transmission was not repairable and that they had found metal pieces in the transmission. They informed us that the only way to repair was to replace with a new transmission. They informed us that these transmissions are faulty and that it’s common for them to replace transmissions in suburbans about twice a month. We were not happy to find this out because this is the second transmission in a second Suburban that we have owned that we have had to spend $12,000 on between both vehicles. The car was out of warranty, Therefore, the expense was totally on us. I need help trying to see if I can get reimbursed for these expensive faulty transmissions that are not our fault! We have serviced car when due. There were 4 small children in the car and we could’ve had a tragic accident because car quit suddenly! Please help!

The contact owns a 2020 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the steering wheel became firm. There was no warning light illuminated. The contact stated that the steering wheel returned to normal operation upon depression of the brake pedal. A week later while the contact's husband was driving at an undisclosed speed, the steering wheel became firm again, and there was no warning light illuminated. The contact stated that recently while driving 50 MPH, the "Service Power Steering - Drive with Care" message was displayed. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not yet diagnosed or repaired. The failure mileage was approximately 55,000.

I put vehicle in Chevy dealership 7/8/24 for cold start knocking sound. Dealers called 2 days later said it was defective lifter issue on the 6.2 liter GM engine.Dealer ordered new engine.on 8/23/24 while test driving vehicle with new engine in it while driving on the highway a fire started under the engine. I was told by dealer that people were telling the driver the vehicle was on fire. He abandoned the vehicle on the highway as it burned up inside and outside. Fire trucks put the fire out.Vehicle is total loss. Waiting two weeks for GM to tell me what they will do to help me. No reply to phone calls or emails unless I call them to check and find out what is going on. I wrote email to GM CEO and no reply. Insurance for me offered me pay out of current value. GMis supposedly going to investigate the vehicle and the cause of fire. Lifter issue is widespread on these engines. Many lawsuits. Vehicle is still in dealer lot burned up waiting for gm to investigate it. I am getting no resolution from GM to help me fully recover from this with new vehicle. If no one had told mechanic that vehicle was on fire who knows if he would have gotten out safely before engulfed in flames. I could not upload additional photos due to site no working.

Fuel injector failed and pumped too much gas into cylinder causing gas to get into engine oil and ruin engine. GM claims they are building the replacement engine, but won't give any estimate of when it will be fixed. Other dealers that are receiving these engines will not sell the engine to my dealer. I believe there is a bigger problem that GM will not admit to and they should be held accountable. Four months is too long for this situation to exist!
