Check engine light with rough shifting and vehicle wouldn’t go in reverse. For safety reasons we had the vehicle towed to our local Chevy Dealership. Transmission needed a valve body rebuild. This is a known issue with this transmission but our VIN wasn’t under that recall.

Unmodified 2022 Chevrolet Suburban with 53K mi, driving 25 mph on paved county road. Without warning the upper ball joint on the right front side sheared off. There were no sounds, no bumps or grinding, truck is routinely maintained, cleaned and inspected - this was out of the blue. If we had been going faster it could have been a disaster. The dealer confirmed it is the upper ball joint. Significant mechanical damage has included the upper control arm and drive line (4wd). We are working with GM to get this repaired. It certainly seems like a Serious Safety issue. I have seen many reports of this problem.

2/24/2026 Sitting at red light, very busy road, vehicle cut off and said push to start. Vehicle would not start and would not shift out of park to push out of road. Very dangerous to be stranded in moving traffic. Had to be towed to dealer and it's still there waiting on engine replacement.

Engine locked up going 75mph on highway. The vehicle's 6.2L V8 engine was recalled in 2025. Result of recall inspection was to change oil type to 0w-40. The vehicle is in the process of being inspected by dealer.

My 2022 Chevrolet Suburban 6.2L, approximately 96,000 miles. Vehicle was taken to dealership for transmission warning message and returned as “repaired” with a software update. The following day, February 12th, while driving at highway speed on the expressway, the vehicle suddenly lost power without warning. A message appeared instructing me to press start, and the vehicle shifted into neutral and stalled. No warning lights were illuminated prior to the stall. This created a serious safety risk due to sudden loss of power at highway speed.

My vehicle was subject to a GM recall involving inspection of the 6.2L engine. The recall inspection was completed by an authorized GM dealership at 58,581 miles. The vehicle was cleared as passing the recall criteria and returned to me. Within fewer than 10 miles after leaving the dealership following the recall inspection, at approximately 58,590 miles, the vehicle experienced a sudden loss of propulsion while traveling at highway speed (approximately 65 mph) on a divided U.S. highway while ascending an incline. The vehicle shifted into neutral and lost engine power without warning. Steering and braking remained functional, but the vehicle lost forward motive power in the left lane of traffic. Attempts to restart the engine resulted in a loud mechanical thud, and the engine would not restart. The vehicle was towed to the dealership. The engine is now being replaced. Prior to this incident, the vehicle had previously undergone an oil consumption test related to engine concerns before the recall campaign. This failure occurred shortly after the vehicle was inspected and cleared under the recall procedure. I am reporting this due to the sudden loss of propulsion at highway speed following recall inspection and the subsequent need for complete engine replacement.

“Service safety restraint system” light came on. I feel this is a defect and a serious concern. I’ve seen where others are experiencing the same issue. I bought this vehicle specifically because I wanted to a safe vehicle to drive my 4 children around in.

I own a 2022 Chevrolet Suburban RST that has experienced ongoing mechanical and safety issues over several years. I first began reporting drivability concerns to General Motors and the dealership in 2023 and continued contacting them throughout 2024 and 2025. During one dealership visit, a sales advisor rode in the vehicle with me and stated they did not observe any issues, despite my continued reports. The vehicle later suffered a loss of propulsion and required a full engine replacement. The radiator and cooling components were also replaced by a Chevrolet dealership. Due to ongoing concerns for my safety, I contacted General Motors multiple times, requested an executive buyback, and asked about Lemon Law options. GM advised that the engine had been replaced and that I needed to take ownership of the vehicle. After picking up the vehicle last Wednesday, I immediately noticed a persistent sweet coolant/radiator odor inside the cabin and outside the vehicle that continued for nearly a week. I also experienced engine hesitation/stuttering when stopped at traffic lights as the auto start/stop feature reengaged. I attempted to contact GM again regarding these concerns prior to today’s incident. Today, while driving, the vehicle displayed an engine overheating warning instructing me to turn the car off immediately. I safely pulled over and shut the vehicle down and am currently stranded roadside. Given the repeated failures, history of loss of propulsion, multiple repair attempts, denied buyback requests, persistent coolant odor, drivability issues, and now overheating shortly after engine and radiator replacement, I believe this vehicle presents an ongoing safety risk and request formal investigation.

Car says "service safety restraint system" and airbag light comes on intermittently. Dealer won't cover under safety restraint warranty. They site TSB about a wire that GM made too short but are not sure it will fix it. This car has 42,000. We are worried the safety restraint system won't work and we carry 4 children in our vehicle. This should be covered and a safety recall.

On Saturday, 11/29/25 @ 3PM, while driving on I-75 from GA to MIA, our 2022 Suburban VIN: [XXX] sudden & unexpected had a mechanical failure. Without warning, vehicle stalled/ stop while traveling at highway speed, leaving us seconds to maneuver to the side. This failure created an extremely dangerous situation that could have resulted catastrophic or fatal accident for my family. Check engine light came on (code P102A). An officer stopped to assist & arranged car to be tow which we had to pay $135 to nearest Chevrolet dealership. Since the dealership was closed, I was forced to stay an additional night in a nearby hotel and paid $106.46. The vehicle was inspected by Countryside Chevrolet, who diagnosed the issue as a failure of the fuel pump control module however I was informed that this VIN was not covered under warranty or any special coverage, despite the fact that we experienced the exact same failure on our 2021 Chevrolet Tahoe, which was covered under warranty for this same defect. I was forced to pay $708.72 for the repair. This inconsistency is unacceptable—especially considering GMs extensive history of complaints, recalls, & class action litigation involving defective fuel pump & fuel system components, which present a well-documented safety risk. I filed a complaint with GM Customer Care (Case XXX). I submitted all required receipts for repairs, towing & hotel, however GM denied my claim without providing any explanation, only stating VIN was “not covered.” Also, GM refused to provide a written justification & my request for a manager callback was ignored. No consideration was given to the safety implications of this failure. This response is unacceptable & demonstrates a failure to take responsibility for a known safety defect. Demand: Given the seriousness of this incident, the documented defect, & GM’s prior knowledge of same failures, I demand full refund of $950.18 for expenses. This situation could have ended tragically. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Car initially started stuttering on the high, check engine and traction control lights came on. I immediately went to the nearest Chevy dealership a mile away. Initially I had 20 error codes. The problem was the Left side lifters 4 of 8 stop working. Dealership recommended Replace Left lifters, 2 push rods, valve cove, head gasket. $5000. After starting the work. The technician could not repair the lifters because my camshaft is pitted and the RODS were rotating. Their recommendation is to replaced the whole engine to fully fix the problem. $12000 with 3 yr warranty. My SUV just 100kmiles.

Onstar, my vehicle's core safety communication system, stopped working without notice, without an alert on the dash. Nothing. I press the onstar button and nothing happens. What if I was in trouble? Didn't have my phone? The issue was not communicated to me through the infotainment system. This seems like a serious issue.
