My rear passenger door flys open while driving. It happens during very cold weather. It also will not latch when trying to shut it after getting off the road and trying to shut it. My daughter has been in the seat next to the door each time and it has happened multiple times. Betten Chevrolet has tried to fix it twice and it is currently in their shop. This is totally unsafe!.

While driving at highway speeds my vehicle lost steering the radio and the hvac turned off. I had abs and brake lights on the dash as well as a service stabilitrac message. The vehicle completely shutoff and I almost had an auto accident. I have not taken it anywhere as I’m to afraid to drive it for fear of having an accident.

I've taken this SUV to the chevy dealership 4 times now for the same issue. SUV will not start at times then starts, it will even turn off on the road without warning. New battery and chevy can not find out issues $500. 00 later. The brake pedal becomes hard to push down, and it will not start: wait 10 mins or so and it will start. Even the remote start at times will not work. Chevy has had it for 30 days at a time and I'm being told to bring it back when it happens, how do I that!.

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.

The vehicle caught on fire in our garage the vehicle had been parked outside than moved into the garage nothing smelled like smoke after it was parked other than the exhaust after I got out of my Suburban I have a good idea what caused this but until its done being ispected I happened to look back and saw a flame in the Suburban coming from the center area of the dash on the right hand side of the divers seat I thought for sure it was gonna blow up the dogs were in the back of the garage behind the vehicle off to the side I started screaming and calling for help and had to go around the house to the front door to get my husband and him and one of my sons went out there why I called 911 and was with my other son whom has a disability and they told us to get out of the house and I could not get back to the garage we were on the other side of the house going to go out on the patio my other son and husband were in the garage trying to put it out and getting to the two dogs my son went through the smoke to reach the dogs were one ran out on her own and the young german shorthair was in shock and he had to carry the 2 year old out and put them in a safe place but my husband was still trying to put out the fire he hooked his pick up to the Suburban to try to pull it out of the garage and it moved maybe a few inches he was stuffing wet towels on it also to try to stop it nothing worked the fire dept showed up and police after having to tear the inside of the front of the dash out our home owners insurance adjuster was out yesterday the Suburban has had multiple and thousands of dollars of mechanical issues even gm putting a new engine in it after only a year in a half of owning it fluid got pushed up into the wiring after a service last year there was splater inside the dash glass after a new steering wheel was istalled and I asked the dealer if they could fix that and they said that they didn't go inside there the amount of detail that has led up to this is huge.

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.

The complete infoentertainment system went out within one week of purchase and has been in the dealership possession since. The dealer’s service department tried to perform updates on the system after the radio went out and it caused the whole dash to go completely black and they haven’t been able to get it to turn back on. The vehicle has been in the shop for 8 weeks now and no estimate when I’ll receive the vehicle back. Since the dash is black you can not see the speedometer, gas gauges, etc and it is not safe to drive without it having fully working electronic components. The dealer is next going to try and replace the radio but that part is back order indefinitely.

While driving, the vehicle has repeatedly experienced sudden loss of power and electrical failures without warning. During these events, the dashboard flickers, warning messages appear, and the vehicle shuts off or goes into reduced power mode. When this occurs, steering becomes extremely difficult, braking becomes stiff, and the vehicle cannot accelerate. These incidents have happened multiple times in different driving situations, including: at stoplights while pulling into intersections backing out of parking spaces driving on public roads, including dark rural roads driving with my three minor children in the vehicle on at least one occasion, the vehicle shut off while pulling onto a road with oncoming traffic, leaving us stopped in the roadway with no power and limited steering/braking. This created an immediate and serious risk of collision. The vehicle eventually restarted after several attempts. The problem has occurred repeatedly over many months. Multiple independent repair facilities have attempted to diagnose and repair the issue, but no definitive cause has been identified, and the failures continue. The vehicle has had numerous electrical, sensor, engine, and powertrain-related repairs, yet the loss-of-power events persist. Because the vehicle can suddenly shut down while in motion and compromise steering and braking, I believe this is a serious safety defect that could result in a crash, injury, or worse.

I own a 2022 Chevrolet Suburban and bought the 72k mile extended warranty. Recently my telematics module went bad which is covered by the gmpp. I lost wifi, my clock is wrong everytime etc. However general motors no longer makes this part anymore. Parts department utilizes a third party company called specmo for a refurbished authorized unit. However, gmpp will only cover the original msrp not the inflated price from the company specmo that gm uses for these parts. This part is 100% covered based on an msrp for a part that they no longer use and states that policy does not allow them to cover the full cost over the original msrp of the part. This is an issue that is all over the forums and internet and is ridiculous that gmpp is an extension/better than manufactures warranty yet they will not fully cover the full cost of the part that is covered. A few days later I was driving and my abs, traction control, steering, brakes, everything was flashing and not responsive or dramatically reduced like my brakes where I could not stop immediately with me and my 5 kids in the car.

My vehicle completely shuts off while driving. All of the components on the dash and even my steering wheel moves into the prestarted vehicle position. It has happened 3 times in the past week now. One particular instance, I was on the highway and thankfully it came back on immediately before completely stopping but shutting off while driving 65mph is so dangerous.

Onstar module failed, no longer have wifi, navigation or other onstar supported features. Cannot perform system updates for vehicle due to onstar module. Cannot use app due to onstar module.

The engine light comes on and then the rpm's drop to 35 and a notification comes up that says "reduced acceleration. Driving with caution". If I stop and turn of the vehicle and restart the rpm's will be better but the truck still seems to have a difficult time increasing in rpm's and accelerating gears. It's incredibly dangerous as if I'm driving at a substantial speed on the highway or freeway and it drops rmp's rapidly I'm likely to be in an accident which could be detrimental. The dealer has had my vehicle on two separate occassions. The most recent time they've had it for 5 days and still do not know what's wrong with it. The engine light will not turn off.

My Suburban locked itself with the keys inside of it. It is available for inspection. I had a two-month baby in the car on an 80-degree day trapped for over 10 minutes. At that young age they have no temperature regulation. I took the vehicle into a local mechanic, and it was confirmed. It has not been inspected by the police, manufacturer, or insurance as we bought this vehicle outright from a facebook ad. There was a suspension message that appeared on the dash, and we bought it like that. However, I'm unsure to how long that had been on prior to that. My husband was going to work on it over the next weekend as it was supposed to be a work vehicle for him.

After a major hvac repair involving the evaporator core (performed at a Chevrolet dealership), my vehicle began experiencing serious electrical issues. The second-row 12v outlet no longer functions, and the vehicle has gone completely dead three times while the engine was off due to the auto stop/start system — once while stationary on a major highway, creating a dangerous situation. Each time, the engine failed to restart automatically, and the entire electrical system became unresponsive.

Driving down to florida, no warning, no lights, never any issues except a belt replacement. I get oil changes, tire rotation every 3500 miles. Almost got killed doing 75 miles per hour, engine sputtered, totally shut down. Coasted onto an exit ramp thank god it was right there or we could of been killed. Tow truck towed to davis chevy gainsville, they called me on Monday said good news I have a warranty bad news total engine failure, will take 3-4 weeks to replace. Now I am trying to find a gm rental large enough to get me and my family back to TN since gm said they will only pay for a gm rental car. Scary, could of gotten killed. No notice from gm about any possibe problems. . . . We almost got killed and crashed along with the other drivers on the road. Thank god it was a Sunday and 6 am so not much traffic or it would of been worst.

I have had my cruise control set and my car will slam on the brakes with no vehicles in front of my car or on each side. This has happened multiple times, it doesn’t matter if I am going 40mph or 60+mph. I have taken it in and they say there is nothing they can do for the issue. I’m worried for the safety of myself, my family, and my unborn child. As well as any cars around (behind me potentially) when this happens. I do not want to unintentionally cause an accident.

There is an electrical problem with driver side door harness which causes my car not to start causing me to have to keep replacing the fuel pump from malfunction of ground wires leading to the fuel pump and ecu from what I am told.

Main display, driver display, and hud froze while driving. Speedometer froze as well. Main display goes back while the driver display freezes. No blinkers worked. This happened 3x throughout the day. Only way to reset is unhooking the battery.

Onstar module factory defaults/malfunctioning - power button don’t turn on so there’s no internet connection. This effect all the safety features in the car. Please recall. There has been numerous incidents reported online to this particular default.

Sat may 3rd we went for tire change from that date since that day, every time we try to start the car there’s always a different warning light the warning light is never the same issue. On may 15 when we received a warning light about transmission we went to the dealership that day they said they were about two weeks backed up but flushed the transmission and paid $504 for the service. Since that day we also received numerous warning light which include. Driver window. Esc. Winshield fluid. Tire pressure. Lift gate open. Forward collision system unavailable. Your 2021 Chevrolet Suburban detects a battery, starter or connection issue. Lastly the check engine light came on and the car won’t start.

I am contacting you regarding a critical engine failure in my 2021 Chevrolet Suburban lt, which is equipped with the l84 5. 3l v8 engine. Due to a valve lifter malfunction, the engine suffered catastrophic failure, with metal shavings found throughout the oil system and internal components. I’ve been quoted approximately $14,000 by the dealership/service center to replace the engine, and the vehicle is currently awaiting repair. I was driving the car with my son when the vehicle began to shake, make ticking noises, and the check engine light went on. I pulled off the road and several error codes popped up including "service esc" and "service traction control. " this is the second time that a lifter valve has failed on this vehicle. In 2022, the lifter valves on the left side were replaced under warranty. It appears one of the left side lifter valves failed again, this time causing significant cam shaft damage and damaging the engine. Given that this issue appears to be affecting many owners with similar engine configurations, I would appreciate your assistance in investigating this matter to see if these issues stem from possible manufacturing defects which could result in engine damage or failure. I reached out to general motors to ask if I qualify for extended coverage or any known service programs to address this situation and they told me I should talk to the dealership because they are unwilling to offer assistance. I've attached receipts for repair of the lifter valve in 2022 and the current diagnosis of engine failure, cam shaft damage, and lifter valve failure. This vehicle is only four years old and was regularly serviced by general motors. It is available for further inspection. Please let me know what other documentation or information you require. Thank you.

Loss of steering, jerks the week right out of your hand and then you are unable to turn the wheel. Engine stalls and you have to try to coast to the side of the road, put in park and try to restart the vehicle. Service stabilitrak warning appears on display, alarm sounds, radio beeps and display goes blank, navigation compass does not work. There is a current technical service bulletin for these issues: #18-na-161, document id 5075841 that lists the years from 2014 to 2020. There were product safety recalls issued: 17276 loss of steering assist, reference number:n172085440 for vehicles listed in this TSB for 2014 and 2015 but no recalls for later vehicles with the same problems.

My vehicle suddenly stalled while driving. I later replaced the battery and discovered the telecom module was damaged, making the onstar system inoperable. Gm disagreed with my warranty claim and required me to replace the module at my own expense. I discovered the same issue is common in various gm models from 2023-2025. My Suburban and yukon both have the same issue, making them defective. However, gm will not provide a free replacement under warranty.

When driving down the road, all gauges drop to 0, car continues to drive. When I pull over and try to turn the car off it turns everything off except the engine. I can’t put it into gear or restart the car. Battery has to be unplugged to get it to turn off. All lights will start flash across the dash. Service air bags, service trailer brake, service side detection, etc.

Issue: the vehicle intermittently displays a “key not found” or “no key detected” message on the dash and refuses to start, despite both original factory-issued key fobs being present and having fresh batteries. The issue began in summer 2023 and has progressively worsened. The vehicle has stranded our family multiple times, sometimes requiring a tow, family impact, missed obligations. Luckily for all urgent needs like trips to the er or urgent care, we were able to use our other vehicle, but we no longer have that vehicle and it is important that our sole vehicle be a reliable one. Impact: •two emergency room visits and multiple urgent pediatric appointments affected •forced to rely on one family vehicle for months •paid for tow and fob batteries •multiple instances of no rental coverage •gm and dealers often declined documentation or action due to the issue being “intermittent” ? request: we believe there is a systemic defect in the Suburban’s keyless entry/ignition system (likely receiver or antenna module). We request that NHTSA investigate and that gm be required to issue a recall or permanent repair for affected models. This issue poses a safety concern and has created financial and logistical hardship for our family.

Engine replacement at 120,000 miles. I was told by mechanic that the 2020 Suburban's have a problem with the fuel injector wiring harness dry rotting and the sensor changing the engine from v8 to v6 when on highway going bad causing misfire in engine and ruining the engine.

Incident report vehicle information: year: 2016 make: Chevrolet model: Suburban I am experiencing a recurring issue with my 2016 Chevrolet Suburban involving the steering column lock module and the theft deterrent system. The truck intermittently fails to start, displaying a "theft deterrent" warning message on the dashboard and lighting get dim on the display. On some occasions, after waiting approximately 10 minutes, the vehicle starts, but other times it does not. Additionally, there are instances when the truck starts but cannot be shifted into gear. To address the problem, I have attempted to disconnect and reconnect the battery to reset the system, but this has not resolved the issue. The problem appears randomly and unpredictably, creating significant inconvenience and safety concerns, particularly in situations where I am stranded or unable to move the vehicle. Impact on safety: this issue poses a risk to my safety and the safety of others. The inability to reliably start or move the vehicle could lead to dangerous situations, especially in emergencies or high-traffic areas. It is also concerning that the theft deterrent system may be malfunctioning, potentially leaving the vehicle vulnerable to unauthorized access. Resolution attempts: despite attempting to reset the system by disconnecting the battery, the issue persists. Online forums and anecdotal evidence suggest that this may be a common problem with the steering column lock module or related systems in this model. Request for action: I urge the NHTSA to investigate this issue as it appears to affect multiple owners of similar vehicles. A thorough review and possible recall or service bulletin could ensure the safety and reliability of affected vehicles.

First, side detection system warning light would come on, then all dashboard gauges would fail and go to position as if the car war turned off, doors and windows would not unlock or open, series of warning messages would pop up as if all systems were malfunctioning. Car would still drive but if you turn the engine off all electrical systems would stay on for a extended period of time. Vehicle would not start, even with a jump start. After sitting for 12 hours, would start again and repeat shutdown after running for about 3-5 minutes.

Vehicle first start sometimes when pushing the start stop button. Dash illuminates but then goes black as if no power. P129d code appears after being able to start.

I was driving our 2021 chevy Suburban, which had ~107,000 miles on it, at approximately 75 miles per hour. With no other indication, the low oil pressure light came on, then within two seconds I lost all power (motor shut off) and lost electronics in the car. I had to man-handle the vehicle to get it off the road without power or dash controls. Our family was stranded near the California/nevada border with no cell reception in the middle of the night for over seven hours. I spent a fortune having the vehicle towed to a chevy dealership (wild west Chevrolet in yerington, nv) where they indicated that there was a main bearing failure which caused the engine to seize. A full l87 motor replacement is required. The motor is currently on backorder with gm due to the high number of l87 engine failures. Gm has not provided an estimated date of when they plan to have the motor replaced.
