SERVICE BRAKES
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 charged me $800 for the update & a battery that they said was not holding the charge, which I've never had an issue with. I had purchased an extended warranty with this vehicle and I was told it would be a bumper to bumper warranty AS IF I had purchased it new (it was 2 years old). The dealership said this was not a critical software update and was not covered under any warranty. I could have been KILLED or seriously injured or killed or hurt someone else due to my brakes going out due to a SOFTWARE UPDATE that was needed!! This is insane!

ELECTRICAL SYSTEM, ENGINE, STEERING
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.

LANE DEPARTURE: BLIND SPOT DETECTION, POWER TRAIN
Transmission will not go into drive or reverse. This also happens when car is in drive going down the road it will all of a sudden lose power and not go when pressing gas pedal. Vehicle has to completely shut off several times before it will go back into gear. No warning before it started. This can be dangerous when it happens in traffic and I can’t move car out of the road. It has not been inspected yet. Also blind spot warning does not always says it needs serviced.

ELECTRICAL SYSTEM
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!

AIR BAGS
Our 2014 Chevrolet Suburban has been garage-kept since it was purchased new. Within a year of the factory airbag recall replacement, the dashboard began cracking in two separate areas. The cracks have continued to spread despite the vehicle being consistently garage-kept and the regular use of a windshield sunshade.

ENGINE
Vehicle experienced sudden engine malfunction including rough idle, hard misfire, and flashing check engine light. Vehicle was diagnosed with a collapsed lifter and internal engine failure. Metallic debris was found in the engine oil, including silver and gold/bronze particles consistent with bearing material. A Chevrolet dealer inspected the vehicle and determined that the engine requires complete replacement due to internal mechanical failure. Vehicle is equipped with the 6.2L V8 (L87) engine. The failure occurred without warning and presents a safety concern due to potential loss of propulsion. This vehicle is not currently included in the existing GM 6.2L engine recall, despite exhibiting the same failure characteristics reported in other affected vehicles with the same engine and year that were included in the recall. Vehicle has not been driven since metal contamination was discovered to prevent further damage

ENGINE
I want to complain that my 6.2L V8 engine was “inspected” and they deemed it OK, then proceeded to make a requirement of thicker oil for its life. I was also given a long term warranty on the engine, however it is non-transferable, therefore the re-sale value of the vehicle is damaged beyond normal conditions. The engine is suspect, why else would it need thicker oil? The engine is all over the news with the recall, therefore why would anyone want to purchase my used vehicle based on that press and no further warranty? GM needs to make this right! That 10-year or 150,000 miles means nothing to re-sale value if is not transferable.

POWER TRAIN
Transmission is not functioning properly at 74,300 miles. Engine kept slipping while driving uphill and the RPMs were not matching vehicle speed. Could not go above 50mph while merging onto freeway which was very dangerous. Whirring noise occurred every time I accelerated which was also noted By dealer and transmission shop. No check engine lights on. Took to dealer, but the misdiagnosed it since no lights were on. Took to Transmission shop, and they found that the transmission had several issues that were not displayed. Besides the shop running specific tests, there are still no warning lamps or messages displayed on the vehicle dashboard or using an OBD2 sensor.

POWER TRAIN, ENGINE, FUEL/PROPULSION SYSTEM
I have a 2021 Chevy Suburban with the L87 6.2L V8 engine. At 7k miles, we have lost propulsion, leaving the car undrivable. resulted in the dealer replacing all 16 lifters under a recognized bulletin. I never received extended 6yr 100k mile powertrain warranty as described in the bulletin. Since then, There have been 3 other issues with loss of propulsion, resulting in replacement of fuel pump modulator. belt pulley system, One of the incidents left us without power or control of our vehicle on the interstate, with no where to pull over or get out of the way of oncoming semi trucks. The last incident again left the vehicle undriveable at 84k miles, with the dealer currently reporting that it is a lifter and cam shaft issue. Resulting in a 10k bill. They state that it is not covered under the recall of these engines because it is the top of the engine versus the bottom. Clearly, the engine oil problem noted in the recall has contributed to these issues . and the crankshaft not syncing properly with the lifters.

SEAT BELTS
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.

ELECTRICAL SYSTEM
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.

SEAT BELTS
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 serious entrapment hazard and my child could not safely be removed, I was forced to cut the seatbelt to free him. This appears to be a dangerous malfunction of the seatbelt retractor/locking system and presents a significant safety risk, especially for children who may shift or turn in their seats during normal use.

STEERING
On at or about November 1, 2025, I experienced a sudden loss of power steering. I was backing up in a parking and experienced a complete power steering failure. Since that date, it has failed multiple times. There was a recall on the EPS Module in 2015. I have contacted a dealer, they could not find a recall for any power steering issues, when there clearly has been. If there has been a recall for the steering of the same model and make and year, and is clearly a SAFETY ISSUE, this recall in 2015 should cover my vehicle also. I was under the assumption that my vehicle was low on power steering fluid. Proceed to look for power steering pump to check fluid level, no reservoir! Start to investigate, find out I have an Electric Power Assist Motor, and an electric module that can not be replaced when it fails, the entire assembly has to be replaced, no way to replace fluid! I’m in the process of getting an estimate of repair as of 11/25/ 2025. There was no indication of any kind, of possibly failure! There is no data stored in the computer indicating any failure, electrical or otherwise!

ELECTRICAL SYSTEM
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.
