Component or System Failure The vehicle experienced two major mechanical failures. First, the transmission failed and required full replacement shortly after the expiration of the 60,000-mile powertrain warranty. At the time of this failure, the vehicle had approximately 61,000 miles. Second, at 100,119 miles, the engine suffered a catastrophic failure that required complete engine replacement. Safety Risk The transmission failure impaired normal drivability and created a safety risk due to reduced or unreliable propulsion, which could have resulted in loss of power while driving in traffic. The engine failure rendered the vehicle inoperable and could have posed a serious safety hazard if it had occurred while the vehicle was in motion, including sudden loss of engine power. Problem Confirmation and Inspection Both failures were diagnosed and confirmed by dealership service personnel, who determined that full replacement of the transmission and later the engine was necessary. The issues were identified through inspection and standard diagnostic procedures. Warning Lamps or Symptoms There were no clear, persistent, or meaningful warning lamps, messages, or symptoms that would have reasonably alerted the driver to an impending transmission failure prior to it occurring. Any warning indicators appeared at or immediately before the failure. Similarly, there were no significant warning signs that would have predicted the engine failure prior to the need for complete replacement. Additional Information Both the transmission and engine failed at relatively low mileage for major powertrain components. The transmission failure occurred just beyond the powertrain warranty threshold, and the engine required full replacement at 100,119 miles. . These failures suggest a potential defect or durability concern affecting critical powertrain systems.

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.

It seems to have started at center console. We serviced the car 1/19/2026, a thermostat in the engine. The engine was not the source of the fire. We also recieved a "green" clean check list on the car except to check tire pressure monitor. This electrical fire started center console. We had a minor glitch with the radio and navigation system at times, the original system. However we had a green check list in January, 2026.

Suddenly the forward collision note appears on the dash and other warnings appear after and then the power dies to the engine. Must stop and restart the engine for it to reset. Yes, it is available for inspection. While driving at high speeds the forward collision appears, and the car can suddenly die mid drive. Even at highway speeds. No, they claim that they cannot reproduce the issue. It has been taken to the dealer at least 5 times It appeared after seat heat function went out and was worked on

The contact owns a 2017 Chevrolet Suburban. The contact stated that the vehicle suddenly lunged forward while driving approximately 30 - 40 MPH. The contact was able to maintain control of the vehicle. There were no warning lights illuminated. The contact was able to continue driving with no additional failures. The next day while the vehicle was idling at a stop sign, the contact attempted to accelerate however, the RPM increased but the vehicle failed to move forward. There were no warning lights illuminated. The vehicle had not been taken to the dealer. The vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure.

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.

The failure mileage was 122,000.

What component or system failed or malfunctioned, and is it available for inspection upon request? The fuel delivery system has failed. Specifically, the fuel lines are leaking at the connection point on the top of the fuel tank. The vehicle and the affected components are currently available for inspection upon request. How was your safety or the safety of others put at risk? This defect poses an immediate fire and life-safety hazard. Because the fuel leaks while the vehicle is powered on, any spark or heat source could ignite the fuel tank, leading to a vehicle fire or explosion. Additionally, the cabin environment has become toxic; the concentration of gasoline vapors is so high that it causes physical illness. One of my children vomited due to the fumes. The vehicle is currently undrivable because the vapors are intoxicating and hazardous to the health of all occupants. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes, the leak has been inspected, reproduced, and confirmed by an independent service center. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, the vehicle has not yet been inspected by the manufacturer, law enforcement, or insurance representatives. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There were no warning lamps or dashboard messages (such as a Check Engine Light) prior to or during the failure. The symptoms—specifically a strong odor of raw gasoline—first appeared four days ago. The intensity of the odor and the rate of the leak have increased significantly since the initial onset.

DUE TO THE EXCESSIVE BRAKING NECESSARY AND THE UNEVEN BRAKING THAT THIS VEHICLE HAS BEEN RECALLED TWICE SINCE SEPT. 2019, I HAVE BEEN EXPERIENCING EXCESSIVE AND UNEVEN BRAKE AND TIRE WEAR. I HAVE TOLD THE DEALER MULTIPLE TIMES SINCE LEASING THIS VEHICLE THAT IT DID NOT RIDE RIGHT AND THE STEERING WHEEL WOULD SHAKE EVERY TIME I USED THE BRAKES. IT ALWAYS FEELS LIKE I HAVE TO SLAM THE BRAKES TO EVEN SLOW DOWN. THEY FIXED ONE RECALL AND DO NOT YET HAVE THE FIX FOR MY MODEL YEAR, FOR THE SECOND. THE DEALER HAS NOTES THAT I NEEDED BRAKE REPAIR AT 29,000 MILES, BUT THEY DID NOT INFORM ME. I BROUGHT THE CAR BACK 3 TIMES SINCE THEN, NOTING THE EXACT SAME THING. AT 36,000 MILES THEY TOLD ME I AM NOW DOWN TO THE ROTORS AND THE PADS AND ROTORS NEED REPLACEMENT DUE TO UNEVEN WEAR. I EXPRESSED CONCERN DUE TO THE RECALLS AND DUE TO THE FACT THAT I HAVE BEEN TELLING THEM REPEATEDLY ABOUT THE DRIVEABILITY OF THIS VEHICLE, I FIRMLY STAND THAT THIS IS A DIRECT PRODUCT OF THE ISSUE FROM THE TWO RECALLS. THE DEALER TRIED TO USE SCARE TACTICS. I OPENED A CASE WITH CHEVY AND I AM GETTING NO ASSISTANCE. I AM FEARFUL IN THIS CAR. I AM GOING TO GET THE BRAKES AND TIRES DONE BECAUSE MY KIDS ARE IN THIS VEHICLE, BUT WHAT ABOUT AFTER THAT, IT WILL JUST KEEP HAPPENING BECAUSE THE ON ISSUE IS NOT FIXED AND THE OTHER IS NOT PROPERLY FIXED. THEY DO NOT SEEM TO WANT TO STAND BEHIND THE PRODUCT AND I AM GUESSING WILL NOT CARE WHEN GOD FORBID SOMEONE OR SOMEONE'S FAMILY IS KILLED.

HAD A FLAT TIRE ON MY LIGHT DUTY TRUCK EQUIPPED WITH TRAILERING CAPABILITY. TRUCK SPARE TIRE IS RATED FOR TEMPORARY USE ONLY AND SLIGHTLY SMALLER THAN THE TIRES ON THE TRUCK. IF THE TEMPORARY USE TIRE IS ON THE FRONT AXLE WHILE TOWING A TRAILER AT A SPEED IF 55MPH IS IT SAFE IN AN EMERGENCY BRAKING SITUATION ? IS THE MAJORITY OF WEIGHT NOW ON THE FRONT AXLE? GM TOLD ME THE SPARE IS 17 1/2' THE REGULAR TIRES ARE 18' THE OWNERS MANUAL ALERT THE OWNER NOT TO USE 4WD BECAUSE OF A SMALLER TIRE. IS IT SAFE ? HAD TIRE FIXED AND WENT TO COSTCO AND PURCHASED A NEW FULL SIZE TIRE TO REPLACE THE REPAIRED ONE.

The first problem that happened with the 2017 Chevrolet Suburban was we were driving and the 1 of 2 brake boosters gave out. We had to contact with customer service of Chevrolet of informed them about what happened. We took the vehicle to a local dealership to have fixed, then after that we started to have problems with the transmission, fuel pump and the air ride. With the transmission/electrical system you would be driving down the road, the next thing that you will know is that the door locks will lock then unlock, then the vehicle will would let a big amount of smoke out of the vehicle, and then the vehicle would power down to 20mph. You would have to drive 20 for 5 miles until the vehicle would quit and you could drive normal. I was going to go for my mandatory user maintenance and I did not get 2 miles out of town and the transmission went out of the vehicle.

On June 1st, we dropped off our 2017 Suburban Premier at the GM dealer. The suburban was had suspension issues, it was no longer safe to operate. Just before noon, the service advisor called to inform me that both struts and shocks were bad. If I wanted to proceed, repairs would be $4045.67. When asked how this was possible, I was told they hadn't seen this before. They thought this was odd, too. I was told it is common for their to be issues with this type of suspension, but they hadn't seen all of them have issues. I asked about policy assistance from GM, was told to file a claim with the manufacture after paying for repairs. With invoice in hand, I searched the parts online. I found I could buy the shocks and struts directly from GM for $451.14 ea, yet the dealership charged me $831.60ea. We paid the dealership $380.46 more for each part - totaling $1521.84 in dealer markup. I reached out to GM Customer Service on June 1st, opening case# 9-7845670653. I scanned and emailed the invoice and was told it was being send to the next level for review. In the five weeks since this started, I have called GM Customer service seven times and have sent six emails. I have received two emails and two calls. I've been told many different stories by many different people. I was told approval takes two days, then told it would take 14 days, followed with an internal approval problem. In the end, I was told it was a maintenance issue and GM would not be doing anything about. This is a huge safety issue! I no longer feel comfortable or safe in our suburban. I know that I am not alone in this issue, there are complaints of this every where you turn. This is a safety issue, GM should be issuing a recall or extending the warranty on these items. GM should be embarrassed, this is unacceptable!

The passenger seat belt will no longer just click in. In order for us to get it to latch, you have to push down on the red button as your pushing the seat belt in, then it will latch. We bought this used and within 1-2 weeks this happened. But other things happened with the engine and that took priority. It was in the shop for almost 6 months. I'm not sure if the dealer/ previous seller knew about it and they were able to "fix" it so it worked when we bought it. (We are lied to on a lot of things) I'm afraid that it might not hold up in a crash if it's not buckling right.
