2015 Chevrolet Suburban Complaint Log

When our new mechanic was checking over the car, he and his other mechanic both noticed that there was an increased brake pedal effort even though the brakes were in ok condition. Every time I’ve had the car serviced I have them check the brakes because they feel off. The car stops and the brakes check out with previous mechanics but something doesn’t feel right. Our new mechanic then gave me a recall bulletin from GM N192268490 and said he thinks our car is experiencing this issue. The recall was attached to our VIN when the mechanic pulled it up but when we called the dealer and checked the NHTSA website, my VIN number was apparently not part of the recall. I am writing to state that I believe my car may be experiencing the issue stated in the recall bulletin as per my mechanic’s findings. Attached is a copy of the recall bulletin given to us by our mechanic. Please advise.

Pulling off from a stop sign on a hill, the car wouldn't accelerate and rolled back hitting a pedestrian and then jerked forward aggressively burning rubber on the tires. I smell the transmission burning. Luckily the lady didn't want to press charges.

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.

The contact owns a 2015 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. No warning light was illuminated. The contact veered to the side of the road and had the vehicle towed to an independent mechanic, who determined that the transmission had overheated and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 167,000.

Replaced lifters 1,3,5,7 and added automatic fuel mgmt system bypass chip after the vehicle went into limp mode ON THE HIGHWAY. Ran for less than 2000 miles and those same lifters failed a second time and had to be replaced AGAIN. The last incident occurred after about 200 miles and had engine failure, limp mode with multiple sensor failures in the middle of the road in the dark. Limited ability to move it safely off the road.

The braking system on my 2015 Chevy Suburban LTZ failed at slow speeds in a parking lot. I have replicated the issue in both forward and reverse. My family's safety was put at risk in that while backing up out of a parking spot the brakes failed completely and I had to push extremely hard on the brake to get the vehicle to stop. That same behavior occurred while pulling forward into a parking spot, almost hitting the car in front of me. I took the vehicle into a Chevrolet dealer today indicating the symptoms and they said there was no recall attached to my VIN. This exact same behavior in my vehicle is described in [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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!

If I pull up to a parking spot and I’m slowly creeping into the spot, say at a popular supermarket, and slowing down the brake pedal stiffens up and it’s almost impossible to press. I feel like my truck may not stop. If I’m on a slight incline and in a line behind another vehicle, I’ve noticed the brake pedal stiffens up then as well. Awhile ago I thought there was a recall for this for my truck and it was something about the vacuum in the brake pedal. This is a super problem. I have five kids and we are on the road a lot. This has been happening a lot but most recently would be today.

Odometer Fraud. The contact purchased a 2015 Chevrolet Suburban. The contact stated that while attempting to have the vehicle inspected, it was discovered that the catalytic converter was missing, the wires were cut, and a pipe was inserted to muffle the noise. The contact was told that the check engine warning light was turned off and the carbon monoxide was not being cleaned, and that fumes were entering the cabin of the vehicle. The contact also discovered that there was a mileage discrepancy on the vehicle. The vehicle was a dealer sale. At the time of purchase, the mileage was 131,000 and at the time of the inspection, it was discovered that the mileage was approximately 231,000.

The transmission was acting weird and felt like it was revving up and down while going 20-30 mph. After turning into my neighborhood there was a loud clunck like some dropped off the truck and it completely fell out of gear and just rolled to a stop. Shifted it into park, turned the truck off and back on and put it back in drive it went into gear and allowed me to drive to my house but still acted like it was about to drop out of gear completely again. My neighbor has a 2015 Silverado and 2017 Tahoe and both transmissions did the same thing and had to be replaced, all between 100-125k miles. The blind side system constantly goes off when there’s no threat

The contact owns a 2015 Chevrolet Suburban. The contact stated that while driving on two occasions, the vehicle did not accelerate as intended. The contact stated that when the vehicle reached 55 MPH, the vehicle dead stopped, and she was thrust forward, and on the second occasion, she sustained a head injury from hitting her head on the steering wheel. Medical attention was not needed. Additionally, on the second occasion, the vehicle began overheating, and the check engine warning light illuminated. The vehicle was towed to an independent mechanic, where it was codes P0700, P0741, and P0796 populated, and the TCM, torque converter clutch circuit, pressure control solenoid C, and transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was unknown.

Often the brake pedal becomes very hard to push and braking is extremely hindered. There is a recall for this issue that has been done but the vehicle is experiencing the exact same problem again. Dealership says that the vehicle time has expired for anything to be done again. Recall was performed only 5 years ago.

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

Torque Converter Failed

Transmission gives out after 2 min

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.

I have a 2015 Chevy Suburban with a 5.3L v8 motor. At 123,067 miles I lost the lifters in the number 7 cylinder due to the Active Fuel Management (AFM) system. This is an ongoing issue with Chevy motors from2014 to 2021. There is currently a Class Action Law Suite. I am hoping the NHTSA will issue a recall. This repaid cost me $4,000.00 to repair.

When the air temperature is in the single digits the seat belt buckles do not latch or unlatch when pulled on. I thought my seat belt was latch no warning sounds indicating that it was not latch, but when i went to reach for something on my dash it unbuckled. When temperature is above 9F degrees buckles work fine. Both driver and passager side seat belt buckles do not work properly when it is cold out. Just wondering if others have brought this up.

Driving down the interstate and the vehicles transmission just stopped working. The D on the dashboard started blinking and would not keep moving. When attempting to accelerate the vehicle’s engine just revved would not move. It was dangerous and no warning prior to this issue.

The contact owns a 2015 Chevrolet Suburban. The contact stated while driving at 10 MPH and making a right turn to enter a parking lot, the vehicle behind failed to see the contact's turning signal and brake lights therefore did not slow down resulting in the contact being rear-ended. As a result, the vehicle was pushed by the impact of the rear end and crashed into a utility pole where it came to a stop. A police report was filed. There was no medical attention required. The vehicle was towed to a tow lot where it was pending another tow to a collision center. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer was not notified of the failure. The approximate failure mileage was 114,000.

While driving approximately 70 miles an hour and trying to switch lanes, we got a stabilitrack warning and the car shut off for a second and then came back on. the weather was nice and there was no snow or any other adverse conditions. This happened a couple more times on the ride and then when we tried to turn into a parking spot it shut off completely and we had to restart it. We turned stabilitrack off and the car was ok for a couple of short drives. Then driving late at late and we passed another car the same thing happened. Then when we tried to turn our brights on we got the same message. Then we got a brake assist message and then we got a collision alert. The headlights were flickering the rest of the drive and we couldnt use our brights. We had our 4 children in the car and it was shutting down at high speeds and very scary. I looked up our vin and it said that the recalls had been worked on but I dont remember this being done. This has never happended before this. our car would be available for inspection if needed.

TRANSMISSION GAVE OUT WHILE DRIVING ON HIGHWAY YES NO LIGHTS TILL IT JUST STOPPED IN HIGHWAY

Vehicle lost power steering turning a tight left into a parking space at a low speed on 5/18/2024. A second later, the engine and all electrical in the vehicle went dead. The steering locked and nothing electrical in the vehicle was functional. Based on the online information and comments found, this is a significant problem with the 2015 Suburban. The GMC recall number is 14743. The recall was for replacement of the power steering assist motor kit. When I look up my vehicle on the recall listing there are no recalls for my vehicle. There is an obvious problem which is effecting these vehicles and dealers shouldn't question the safety implications of steering and engine failure while the vehicle is moving.

The contact owns a 2015 Chevrolet Suburban. The contact stated that while driving at an undisclosed speed, the vehicle lost motive power. The RPM was elevated. The contact stated that the transmission would inadvertently shift out of gear independently. There were no warning lights illuminated. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred to the NHTSA Hotline.

It started with a glitch with the radio/navigation system flashing back and forth and not working. The cooling fan on the vehicle would run for about 10 minutes. The blind spot warning would blink on and off and there was no one else on the road. Then two days later the check engine light came on for about 5 days. Then three days later there was a loss of battery power and the indication light came on stating the car was in battery save mode. Then two days later the power steering system was lost on the highway and all the warning lights on the dash were flashing. The car stalled and refused to start. The tow truck driver tried to jump the vehicle with a battery pack that would jump a diesel and he only got enough power to put the car in neutral.

The transmission started shifting hard in second gear and also whines at higher RPMs. The code it’s throwing is a Torque Converter Clutch issue. We were put in danger because it almost stalled on the highway. It has been inspected by a mechanic. There were no warnings prior to the failure.

I purchased my vehicle after the recall 19V-645 regarding the brake pump was issued. My vehicle was a part of that safety recall, and the module was reprogrammed in September 2019 (N192268490-01). The pump has not been previously replaced according to service records. I purchased my vehicle from a dealership in April 2021. I recently (late 2023) started having issues with my brakes, having increased brake pedal effort, a hard brake pedal, and increased stopping distance. I have had the brake assist alert come on several times. The issue happens more frequently at lower speeds. My park assist alert also comes on regularly when applying the brakes. I have taken my vehicle to GM several times regarding the park assist issues, but they have only cleared the computer codes and cannot figure out why they keep coming back, as there is no detectable issues with the system. I have also brought my vehicle in due to the adaptive cruise control, as it has also caused issues while using it. It will often apply brakes if it detects a vehicle in another lane while driving, causing the vehicle to “slam” on the brakes going at high rates of speed (I.e. driving on the interstate at 80 mph) and has nearly caused accidents, as the vehicle becomes hard to control, and the risk of following vehicles not having the reaction time to avoid a rear-end collision is increased. My particular vehicle does not have an option to switch between regular cruise control, and adaptive cruise control. After talking with GM, they informed me the only way to “fix” the issue is to completely replace the module with an updated module that allows the option to turn off the adaptive cruise control, which is quite costly to the consumer. My vehicle is currently at a GM service department, and has been diagnosed that the brake pump has failed, and needs replaced. They are claiming that it is not covered under the recall. It is not covered under GM’s extended warranty due to mileage restrictions.

transmission failed causing to replace do to the system on CHEVY motor changing from 8 cylinder to 4 cylinder and a thermostat on a transmission line.

The contact owns a 2015 Chevrolet Suburban. The contact stated that the odor of fuel was present inside and outside the vehicle. The contact stated that upon investigation, it was discovered that fuel was leaking under the front of the vehicle.

The local dealer and manufacturer were notified of the failure, but no assistance was offered. The failure mileage was 155,000.

The contact owns a 2015 Chevrolet Suburban. The contact stated that while the vehicle was parked and turned off without the key in the ignition, her daughter bumped into the gear shift selector and inadvertently shifted the vehicle into reverse. As a result, the vehicle began to roll, coming to a complete stop after colliding with another parked vehicle. The air bags did not deploy. No warning lights were illuminated. The vehicle was taken to the dealer, who was unable to duplicate the failure. The vehicle was not repaired. A police report was not filed, and injuries were reported. The contact reported bruising sustained while attempting to stop the vehicle but had not sought medical treatment. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was unknown.

The transmission has failed several times during driving with no check engine light or maintenance required light appearing. I get monthly reports saying that the engine does not have any problems. My safety and others safety were put at risk because any time during driving the engine can lose power and you will no longer be able to accelerate. This could be dangerous on roads and especially highways if you are traveling at fast speeds and cannot get out the way of others possibly causing an accident. I have recently taken my vehicle to a car mechanic shop and they say this is a common issue in the transmission of similar makes and models around this year. There were no previous warning lamps or messages from the vehicle or the monthly diagnostic reports I receive monthly. The problem started occurring before 150,000 miles.

While traveling on the highway, my dashboard indicated that my transmission was overheating. I had to pull over immediately and turn off the engine to allow it to cool down in the middle of heavy traffic in an unsafe location almost getting hit my multiple vehicles at a high rate of speed. All regular maintenance has been done and it only has 119,000 miles. I purchased it in May 2023 with 113,000 miles from a reputable dealership and this occurred in October 2033, only 5 months later. There is a recall for this model and my vehicle is not included, which seems to be an ongoing issue with other consumers with the same year, make, and model. The transmission needs to be replaced and it’s costing over $6,000.

The # 7 cylinder valve lifter in the 2015 Suburban engine fails when accelerating in certain situations. This has happened to this vehicle twice at and expense of rebuilding the engine. The in both cases the vehicle was accelerating into fast moving traffic. When the lifter fails the engine loses power and no longer accelerates which requires swerving out of traffic, back to the shoulder to not get rear-ended by on-coming traffic. The problem was confirmed and the service provided indicated that this was a significant issue with this particular engine. Basically, it happens to many of these vehicles. The engine has been rebuilt twice while I have owned it. When the lifter fails the check engine light comes on. These failures occurred on September 24, 2021 and again on September 9, 2023.

Chevy transmissions for the following years of 2015-2019 have has extensive problems. They include hard shifting, break down, and full blown blowing up on consumers. This has cause consumers to fork out on average $6000 to have a transmission replacement. There is over 2000 people on reddit who have reported this issue and chevy/gm has not opened a recall due to the [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Periodically the steering goes away and makes the vehicle hard to maneuver and I also get some warning lights with it.

While traveling on a busy highway with cruise control on the rpms would go up about 2,000 then drop back down to normal. This happened all the way home (1hr 30min). No lights on dash or warning went on. Then when I was back in the city, I was at a stoplight turning left and pressed the gas it engaged and started to move and then the rpms shot up to 4,000 and the car didn't go. No warning lights, messages appeared.

Wireless charger built into center console malfunctioned and wires melted causing smoke to fill the car, armrest felt hot to touch.

I went to put my seatbelt on and the cable broke at the anchor point between the door and base of the seat.

When I attempt to speed up or slow down my truck hesitates, and it's followed by a significant shake, like a shudder, and sometimes it just jerks, or clunks, like it's doing a very “hard shift” when the automatic transmission changes the gears. Sometimes it shifts so violently, I feel like I got hit by another vehicle. I've also tried to accelerate into traffic, and the truck hesitate and then abruptly and violently jerks into gear. It creates a big traffic safety issue! Other times the transmission shifts gears so hard that it slams the truck forward, and makes feels like I've been rear-ended. Now it barely shifts!

TRANSMISSION HAS FAILED...

The contact owns a 2015 Chevrolet Suburban. The contact stated while driving approximately 35 MPH and attempting to make a left or right turn, the vehicle lost motive power. The contact stated that the failure was intermittent but has been recurred more frequently at slow speeds. The vehicle was not able to be restarted. The vehicle was towed to a local dealer however, no failure was found. The contact stated that the failure reoccurred, and the local dealer was not able to duplicate the failure. The local dealer suggested that the battery needed to be replaced. The battery was replaced; however, the failure persisted. The vehicle was taken to an independent mechanic and remained with the independent mechanic. The vehicle was not repaired. The contact related the failure with the NHTSA Manufacturer Communication Number: N212333901 (Loss of Power Steering Assist). The manufacturer was not made aware of the failure. The failure mileage was approximately 150,000.

Braking is diminished when vehicle is moving at slow speed and brake pedal is pressed. The vehicle brake assist engages by pulsing, increasing the braking distance by not stopping the vehicle no matter how hard the brake pedal is pushed. Emergency brake is used to prevent vehicle from colliding. This may be related to NHTSA 19V645

Side detection module smoking causing dash malfunction and electrical issues

The vehicle will display “Service Trailer Braking System,” as well as “Service Front Camera,” “Service Driver Assist System.” These messages along with audible alerts will sound while driving. At random intervals, the forward collision system will also activate with no objects in sight. This causes the driver to become distracted or react quickly in unnecessary manner. This can increase risk of collision when the driver becomes distracted. The vehicle has been taken to Chevrolet multiple times and we have been told a faulty wiring harness is the cause. We own two of these vehicles, same make, model and year. This has happened in both vehicles.
