2023 Chevrolet Suburban owner complaints

After just getting our vehicle back on 12/11/25 from our incident on 11/9/25 when my wife was driving at 70 MPH on the highway when the engine blew the first time. Approximately 1300 miles later and 15 days after we picked up the vehicle when I was merging onto the highway the vehicle had a sudden power loss and a smell that filled the cabin. We were able to drive to the next exit and while the vehicle was idling it sounded awful. The check engine light started to flash along with the TCS light and the collision warning lights. After getting to a parking lot when called OnStar to tow our vehicle to the closest dealer. I have not received any updates yet but it is very similar to what happened the first time when the engine needed replaced.

My 2023 Chevrolet Suburban High Country (VIN: [XXX] ) suffered a sudden and dangerous engine failure while my wife was driving 70 mph on the interstate returning from our child’s sled hockey tournament in Ohio. The vehicle gave no warning lights, alerts, or diagnostic messages before the failure. While driving in the right lane, the vehicle began losing power and making a loud noise. My wife exited the highway and contacted OnStar, who told her the tow would take over an hour and only cover three miles to closest dealer, leaving her stranded in an unsafe area. She attempted to carefully reach a nearby dealership. During this attempt, the vehicle completely shut off and she lost all engine power. The vehicle lost all power making the final turn into the dealership coming to rest in the mi

My 2023 Chevrolet Suburban with the 5.3L V8 engine has experienced lifter failure twice within less than [20,000 miles]. Both times the vehicle developed a misfire, engine belt like noise and was diagnosed by the Chevrolet dealership as having collapsed AFM/DFM lifters. All oil changes have been done at the dealership using GM-approved oil. The issue appears to be a known problem on 2021–2023 GM vehicles with the 5.3L L84 engine. GM has a technical service bulletin (PIP5776H) regarding lifter collapse, but no permanent fix has been provided. I am concerned this could lead to engine failure or stalling while driving, creating a safety hazard.

The contact owns a 2023 Chevrolet Suburban. The contact stated that while driving at 10 MPH, there was an abnormal rumbling sound coming from the engine, with the check engine and traction control warning lights illuminated. Due to the failure, the contact restarted the vehicle and drove to an independent mechanic. The mechanic performed a diagnostic test on the vehicle and discovered a misfire in cylinder #3. The mechanic replaced the cylinder #3 ignition coil; however, the failure persisted. The contact then had another independent mechanic at the same shop inspect the vehicle, and the mechanic diagnosed the vehicle with engine failure. Neither the dealer nor the manufacturer was notified of the failure. The vehicle was not repaired. The failure mileage was approximately 52,000.

Since purchasing the car in March 2023, the battery has died 5-7 times. We contacted our dealer and they claimed nothing wrong and the battery was fine. We have contacted them about this issue and there is no fix. They performed an update in June 2025 which was supposed to fix it but it didn’t. The latest it has died is November 25. There was nothing left on for the battery to die. I have 4 children and it’s starting to get very cold outside. I live in a rural area with poor cell reception. I am worried I’ll be stranded somewhere with a new baby and 3 younger children.

On Star module failure. The module controls many different safety features and it has failed and has been on a backorder for months creating a safety issue every day.

While driving on the highway at night during rainy conditions the wipers stopped in the up position, and at the same time, the headlights turned off. After a few seconds they resumed normal operation. My headlights were in the auto position and my wipers were also in the automatic setting. Being as that I was on a highway at night, in the rain, and going approximately 65mph surrounded by traffic, this was an extremely dangerous situation to be in. Without headlights and windshield wipers, my windshield was immediately obstructed and I was unable to see the road without headlights. More so, other traffic might have had trouble seeing my vehicle. This problem has not been replicated by myself or a dealer. It has been random in nature. When the incident happened, there were no warning light

I was driving to work last Wednesday, and I live on a hill. As I was driving, a "Brake failure" alert came over my dash and I lost all control of my brakes!!! I live right off of Main Street, and my options were only to go straight and into a house, or to turn onto Main Street and hope no one hits me or that I don't hit another vehicle. I turned and thankfully no one was coming. At the end of that street I was able to coast into an closed down gas station and park the vehicle. I called the dealership I had purchased this vehicle from 10 months prior, and they told me I had to use OnStar to have it towed to them. I did that, and they towed it to the dealership. The next day the dealership told me the cause of losing my brakes was due to a SOFTWARE UPDATE that was needed!!!!! They

I went to get in my 2023 suburban this morning to travel to the gym. It started but it would not shift out of park. I looked down and noticed the check engine light was on, the ABS light was on, and the park brake light was on with a lock and wrench. I had no issues since I purchased it used in March 2025 and yesterday it was driving fine.

The vehicle was purchased brand new from the manufacturer. Because the third-row seating was rarely used, it was not immediately apparent that the car was delivered without one of the required seatbelts. Once the issue was discovered, it was promptly reported to the manufacturer. However, the customer service representative refused to address the problem, stating that the warranty period had expired. This is a serious safety hazard. A missing seatbelt poses a significant risk of severe injury or death in the event of an accident, and it requires immediate corrective action.

While driving a 2023 Chevrolet Suburban (VIN: [XXX] ), my [XXX] son was seated in the second-row center seat and was properly buckled in with the factory shoulder/lap belt. He turned around briefly to grab something from the back of the vehicle, and during that movement the seatbelt fully extended and then locked in the automatic locking mode. The retractor would not release tension afterward. The belt continued tightening around his torso, and no amount of slack could be pulled back out. The belt became so tight that he was unable to breathe comfortably or free himself, and the locking mechanism would not disengage even after the vehicle was stopped and turned off. The seatbelt remained fully cinched and would not retract or loosen under any circumstances. Because the belt created a se

Multiple time the full safety camera system has failed. The front rear and 360 degree view camera have intermittently failed multiple times. Restarting the vehicle has had no effect on restoring functionality of the very vital rear back up camera, front camera, parking and pedestrian sensors. This is a random occurrence, has happened at least 5 separate occasions since purchase, and occurs intermittently. Date is the last time this issue occurred.

When driving making a left or right hand turn my 2023 Suburban loose power and turns off and it is thrown in N and state to press start to restart my SUV. No codes are given to determine the issue. This has happen a handful of times. It has been taken into Chevy and they are unable to diagnose the problem. During the one visit they stated it was the battery and replace it and it has done it again. This is a very unsafe to drive the SUV as I'm afraid someone will rear end me and hurt me or someone else.

I was driving the vehicle and without warning it just stopped shut off and immediately shot an error code that there was a critical issue with the engine and that the oil pressure was low, and the vehicle would not start and was not drivable. It had to be towed to a dealership.

2023 Chevy Suburban transmission control valve failures causing wheel lockup or deceleration causing the vehicle to be unsafe to operate. Chevrolet refuses to acknowledge.

Car shows ESC error message not detecting brake pads, and locking the wheel.

Vehicle had 14,000 miles and tires were rotated by dealership twice, last one 3 weeks ago. Was driving 55 mph and had a sudden complete deflation and stopped immediately. Tire is completely separated. The outer sidewall is completely separated from the rest of the tire. The tire has never had an injury or other issues. The tire rotation was at Gerry Lane Chevrolet in Baton Rouge, LA. I took the tire in the same day to Gerry Lane Chevrolet service department and they were not helpful. They did not even look at the tire. I am having all 4 tires replaced tomorrow at Costco and will keep the damaged tire and 3 others for any forensic evaluation by your department or designate. I am concerned that this maybe the canary in the coal mine and if there is a manufacturing defect other lives may be a
