ELECTRICAL SYSTEM, POWER TRAIN
I bought this vehicle in August 202 from Bayway Chevrolet in Pearland, Texas. The vehicle is now at 101,703 miles. The vehicle is a 2019 Chevy Suburban LT with the 8L43 transmission. Approximately 1 year ago, we started to have issues with the electronic screens - both the dashboard and the radio screen. The screens freeze, change channels and displays without any buttons being pressed or the screen being touched. Due to cost, we have not had this repaired yet, however our usual mechanic has said that he sees this issue all the time in smart technology vehicles. The transmission, on XXX, we were going to a family dinner and the vehicle started shifting hard and making a clanking noise. We turned around and went straight home. The next morning we took the vehicle to our mechanic who said the motor mounts were broken and a tune-up was needed. We got the vehicle back on Monday, XXX. Tuesday the XXX, I drove about 100 miles for work and noticed the vehicle was making a whining sound from the transmission. Took it to mechanic, by the time we drove about 2 miles to the mechanic, the entire transmission was completely broken. We now have to pay $5402.19 to rebuild the transmission at only 101,703 miles. I know GM is under a lot of scrutiny with the transmission issues right now and I believe my transmission is another one of those affected.

Oil pressure acting weird. We checked the oil and there were only 2 quarts of oil in truck. I just had an oil change 3 weeks ago. No oil leaks. Engine must be burning oil for some reason.

ENGINE, SUSPENSION
I brought my Chevrolet Suburban High Country in to the dealer pursuant to a recall for engine issues due to a manufacturing defect in connecting rods and crankshafts that can cause catastrophic engine failure. The service center changed the oil viscosity and fill cap and stated that the change should eliminate the issue. I have had persistent engine knocking upon acceleration since then and it is getting louder and more prominent. A suspension warning intermittently flashes as well. Please advise, thank you

ENGINE
We purchased a 2023 Chevy Suburban in January of 2026. In May the vehicle shut off on me at a stop light. The check engine light flashed after I was able to restart it. I took it to the dealer and they said they "couldn't recreate the issue" even though there was an engine misfire code on all cylinders. They told me to come pick it up and bring it back if I had further issues. The second time this happened I had issues getting the vehicle started. This was June 2026 Once I finally got it started and was driving all the service lights started going off and the check engine light started flashing. I took it to a different chevy dealer and was told the same thing. This time I had 23 different service codes that showed up. Including the engine misfire code. So we picked it up and continued to drive it. On July 10th we were towing a 7k lb camper home when we lost all power. Thankfully we weren't driving fast and we're able to stop. This left us stranded at a busy intersection for 2 hours. The car would not go out of neutral. Had we been going 70 on an interstate we could have very seriously been hurt. The car had to be towed back to the dealership where we were told the engine locked up and needed to be replaced. My husband and I had our [XXX] child in the backseat with us. This was a family car that we purchased and told twice that they couldn't find anything wrong with it. The vehicle has been at the dealership waiting on a motor since July 11th.

ELECTRICAL SYSTEM
The infotainment system started taking ghost inputs. We replaced the screen and the ghost inputs are still there. The Human interface module has gone bad. There are many reports of this happening to chevys of similar years. Chevy dealership told me we need to replace the whole system for over $1200. I first started having this problem in 2024. It changes radio stations, moves the display screen, and tries to activate other buttons on the screen. Has also tried to call onstar.

FUEL/PROPULSION SYSTEM
The fuel pump module on this vechicle failed, and there's a recall for 2021 I believe other years should be considered as well since this was a known issue as soon as we arrived at the dealership and they wanted over $400 to replace this part which is only $45.

POWER TRAIN
What component or system failed or malfunctioned, and is it available for inspection upon request? (On our 2021 gasoline suburgan, the rear wheels locked up at free-way speeds, which nearly caused a possibly fatal accident. The lock released but it appears the strain caused rear differential gear teeth to break and the rear differential now needs to be replaced for the vehicle to operate properly.) How was your safety or the safety of others put at risk? (The sudden rear wheel lockup at freeway speeds resulted in temporary loss of control of the vehicle and significant surprise to the driver, who, after swerving into the adjacent lane was able to gain control of the steering and stop the vehicle. Had there been another vehicle in the other lane the MVA could have been fatal for 9 people in the suburban and any other vehicle involved.) Has the problem been reproduced or confirmed by a dealer or independent service center? (The rear differential damage was confirmed by a dealer.) Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? (No.) Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? (No warning or messages. This has happened 3 times over 3 years, always on extended trips 9-12 hours in duration. The first two times nearly caused an accident but no differential damage. This third time, the differential was immediately damaged due to the incident. We have since learned that this is an issue with 2022 suburbans, for which a recall has been issued. A recall has also been issued for 2021 DIESEL suburbans. However, no recall has been issued to gasoline 2021 suburbans, but apparently needs to be.)

Since December 2020, our Suburban has been in for seven extended, documented dealership repair events at Guaranty Chevrolet and Simpson Chevrolet of Garden Grove, totaling 192 cumulative days out of service and $47,560.86 in documented repair invoices — approximately 71% of what we paid for the vehicle. Those repairs have included a complete transmission replacement (58,861 miles), a recurrence of the same active-lifter defect only ten days later, an ignition coil failure, fuel injector and air conditioning failures, an oil pump failure, and, most seriously, a complete engine replacement (66,854 miles) after the dealership documented metal in the oil and filter and engine end play. The situation has continued to worsen. We picked up the vehicle on XXX following the complete engine replacement. Only six days later, on July 6, 2026, the check-engine light returned and we brought the vehicle back to the dealership. We were initially told the issue was a sensor; the following day, we were informed that the replacement engine — which the dealership had disclosed to us at the time was a refurbished unit — was itself defective and would need to be replaced a second time. As of this writing, that repair remains open. In other words, the remedy provided for this vehicle's most serious failure did not resolve the problem, and we are once again without our vehicle. This pattern of failures has caused real, ongoing hardship for our family. We specifically purchased a full-size, top-trim Suburban for its seating and cargo capacity: we have two teenagers at home who depend on us for transportation to school and activities, we regularly care for grandchildren, and our [XXX] daughter has Complex Regional Pain Syndrome (CRPS), a debilitating condition that often requires her to use a wheelchair. The Suburban's cargo space is what allows us to transport her together with her wheelchair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
