general problems of the 2015 Chevrolet Suburban - part 1

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.

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!.

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.

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.

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.

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

The power steering locks up at random times while I am driving my vehicle. It seems to be temporary loss of power steering because it eventually starts working again. It feels almost impossible to turn the car when this happens. I searched online and found there had been a recall on the eps (electric power steering) for this exact issue. I called the local dealership, they told me after searching my VIN that the recall had already taken place in 2019. The repair or recall that was done did not fix the problem.

Vehicle loses power steering when turning at slow speeds which was part of a recall from 2018. Reflashing the module didn't fix the issue and has been doing it again for a year now except that now it occasionally loses power as well and has twice lost power while I was turning and oncoming traffic coming at me. Gm is saying it is not the same issue as the prior recall, but I disagree and that the work done prior didn't fix the safety hazard. An 8 year old vehicle shouldn't be losing power while driving to where the battery cables have to all be replaced. That should have been the work gm did back when they first put out the recall for the loss of power steering.

So my 2015 when I’m slow drive 5mph give it take the steering wheel locks up parking assist lights come on my ac turns off and my screen shuts down.

Driving at a slow speed and lost power steering due to faulty power steering module went into oncoming traffic and drove off road to avoid collision. Recalled 3 years ago for software update but problem happened again and gm would not cover repair.

The check engine, seat belt, stabili-trak, and abs warning lights were illuminated. The contact stated that the vehicle was occasionally towed and taken to the same local dealer on several occasions, where it was diagnosed; however, the failure was not yet determined. The transmission, fuel pump, battery, alternator, and unknown wiring were replaced at the consumer's expense; however, the failure persisted. In addition, the contact related the failure to NHTSA campaign number: 18v586000 (steering); however, the VIN was not included. The manufacturer was made aware of the failure. The failure mileage was approximately 117,000.

The contact owns a 2015 Chevrolet Suburban. The contact stated that while driving under 5 mph to pull in a parking spot, his steering wheel started to feel tight. The contact stated that the power steering warning light illuminated flickering on and off before he lost power steering completely. The contact stated that when the failure occurs it only last for about 5 seconds and the vehicle returns to normal. The contact stated that upon doing his own research, he saw that the same year, make, and model vehicle experienced the same failure NHTSA #18v586000(steering). The contact stated that he has not contacted the dealer or an independent mechanic, however was able to contact the manufacturer. The contact stated that he was advised by the manufacturer to wait on a recall notice in the mail. Failure mileage was 80,000.

Over 600 miles from home. Started vehicle and " service power steering- drive with care" message shows. No power steering. Recall performed previously. Attempted to drive. Within 15 miles power steering came back while traveling 55 mph. The next morning in the rain a repeat. This is a very heavy vehicle with 6 passengers. Hard enough to maneuver with power steering on bag roads. Gm knows there is a problem but like most big companies, they pay off people to avoid fixing issues. Search online and see.

At slow speeds when turning I get loss of steering, service stabilatrak and service park assist as well as truck dies and I lose the radio.

Purchased vehicle in March 2020, have had 4 instances of making a left hand turn and vehicle shuts off. Have read that steering assist recall was done, but from what I've read this is exactly what it is doing, low speed and making a turn. Any suggestions or have others experienced same? date is last time but has happened about 4x s now since last summer.

After recently purchasing a used 2015 gm vehicle from a non-gm dealership, I made a service appointment with a local authorized gm service shop to have three outstanding safety recall issues addressed. My appointment was for 7:30 am on 8/25/2020 and I brought my vehicle to the shop in the morning of 8/25. After 4:30 pm I returned to retrieve my vehicle, and the service shop had not even brought it in to lol at the issues. No work had been performed, despite the service department having my vehicle in their possession not only during the timeframe specifically scheduled for them to perform this service, but the entire remainder of the work day. The safety recall issues remain unresolved.

I purchased this vehicle and was unaware it had open recalls which could have resulted in an accident. The dealership I purchased from did not fix the recalls prior to my purchase and did not inform me there was an open recall.

This happened on 2 occasions. First incident was on 2/14/2020, power steering went out and was unable to turn steering wheel. Had taken to Chevrolet dealership locally and they put on computer and showed low voltage. They assured me it was the batter and that I need an ac delco battery and that would resolve the issue. Even had them hook it back to computer to make sure nothing was popping up wrong and to assure it was just battery. They did and nothing showed wrong after changing batter. I went out of town over the weekend trusting their judgment, with my children. Then on 2/20/2020 it happened again! it was taken again and had 9 things showing wrong on the computer. They now are saying it is the power steering gear. I believe this is an issue that needs to be recalled before someone is hurt. I trusted that it was just the battery. I could have hurt someone, my children, if it had happened and I could not turn the wheel to avoid an accident. I was told that the part is on backorder. I think that says enough if they have it on backorder, there is a problem. Thankfully both times I was able to get it taken to the Chevrolet place safely without injury. Both times it was stopped, once at a red light and second parked and had gotten out for maybe 3 minutes and it popped up on the screen when I got back in vehicle.

Nhtsa tracking # 11308677 - additional and updated info. The problem with our vehicle is that the power assist motor is malfunctioning causing intermittent power supply to the power assist motor, causing the car to become unable to steer or lurch unexpectedly to the left while underway. This is life threatening. The NHTSA approved a recall on the 2015 Suburban for specific dates of build, for which ours is not included according to gm. Nhtsa campaign id 14v19000 is in relation to this issue. Apparently. Our vehicle has the same issue the recall should be extended to cover models made when ours was made. Again, this is a life threatening failure that is just waiting to happen unless gm corrects the issue.

This is a known issue. Loss of steering assist occurred this past week, 3 times. We took the vehicle in for the recall on this item 5-16-19, when the system was "reprogrammed" by the techs at the chevy dealership. We had never experienced this issue. Then last week, the issue occurred. There was a temporary loss of power assist on a long right hand turn at 35 mph when a female was driving which caused some concern. Then yesterday the steering stopped entirely in a parking lot. I arrived and got in the car and was able to steer but someone of lesser strength could not have. I drove around the parking lot and was headed straight to the dealership, abut 5 miles away. The steering came back on. Then halfway to the dealership, what had happened to my wife happened to me at about 40 mph (steering goes out for a second) and the vehicle lurches hard to the right. She was behind me in my vehicle and saw it happen. We were able to get to the dealership. They documented the lack of power steering assist incidents via the computer. My point is that if this was corrected in may 2019, why is it happening again? if you are not expecting the issue, you will be caught off guard and a wreck is potentially unavoidable. What if I had a trailer in tow at 60+ mhp? death could be the result, for the driver or others. If the issue has not been corrected, gm should pull these vehicles off the road and replace them, free of charge.

Tl the contact owns a 2015 Chevrolet Suburban. While the contact was making a left turn, the steering lost power and then returned momentarily. The failure recurred and the vehicle shut off. The contact stated that an unknown stability indicator illuminated and the vehicle made a whistling noise. The vehicle restarted and was taken to the chuck fairbanks Chevrolet (972-408-1571, located at 629 n I 35 e, desoto, TX 75115) where it was stated that there was no recall. The contact was informed to bring the vehicle back if the whistling noise recurred. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 138,000.

When traveling at slow speeds, I. E. , parking lot or restaurant drive-thru line, and making sharp turns, car stabilitrak warning will flash then loss of power steering and complete loss of power will result. Additionally, the media electronics will shut off and restart periodically. This doesn't necessarily happen at the same time, although, this never happens when I am not having problems with the stabilitrak system. (see previous complaint: 11122704) took car for service at capitol chevy on 8/30/19. They said no codes were indicated, however, throttle body was dirty and could have an effect on my issue. Throttle body was serviced/cleaned. On sept. 2, 2019 I had issue with media system and stabilitrak. While traveling southbound on I-85, cruise control set approx. 75 mph, I braked to disengage cruise speed when media system reset. I pulled into my driveway approx. 20 minutes later and while traveling at slow speed and turning in my driveway, the stabilitrak warning came on resulting in loss of power steering. I was nearly at a stop when it happened. Sometimes when the car loses power in these situations it will have to be jumped off to restart. Which happened prior to being serviced on 8/28/19. I read about similar stories on chevy message boards related to 2015 models,.

It's been over two months that I started having problems with my vehicle. When I turn my sterring wheel to make a turn my vehicle turn off;or when I reverse.

You can reach me at( 323)803 -6909.

1) intermittently when turning vehicle at slow speeds, there is sudden loss of steering and electric power steering violently bouncing the wheel back to neutral position when attempting to steer left or right. There is also sudden loss of electricity, engine turns off, requiring to shift to park and restart engine. This issue usually occurs after rain or after car wash (water entering shark fin antenna) 2) intermittent complete power loss throughout the vehicle (occurs especially after rain - when shark fin antenna gets filled with water) and feels like battery is suddenly completely dead. Sometimes it can not be jump started immediately, and after more than an hour, it may be jump started. 3) water leaking into the front left corner of roof (driver side) after rain - again due to shark fin anternna leak. There are many owners of chevy Suburban/tahoe, silverado, gm truck reporting exactly same problems all over internet and on youtube. This problem still exists after the recent 09/07/2018 recall 18v586000 fix. This recall did not help solve this problem. In many youtube videos people report having fixed this issue by replacing battery positive and ground cables, as well as by removing the sound dampening material trapped under g218 ground on the driver side of dash (people have mentioned about increased resistance across g218 ground). .

When pulling into a visitor parking spot at my children's school the steering of my chevy Suburban 2015 became stuck in mid turn. It locked in place for a split second or two causing my car to scrape the bumper of the car parked in the spot next to me. When the steering came back it was extremely loose. My vehicle was in motion and very low speed. I have 3 children involved with pta and carpooling kids around daily. I have been driving an SUV for 12 years and this has never happened before. The car VIN number was indeed part of a steering recall. The recall notice was sent out after my accident. After a claim was put in with my insurance. I am glad no one got hurt. In the meantime the damages to the car I hit has been fixed.

Second time: (8/25/18) in drive-through line at restaurant and steering wheel jerked, power steering warning flashed on dash before car lost all power. I put car in park, restarted car and it happened again. Incident happened at extremely slow speed while making a hard left turn. Restarted car second time no additional problems. First time: (8/8/18) several weeks ago a similar incident happened while my wife was making sharp turn at low speed into a parking space at grocery store. Took car to local chevy dealership and they replaced a electronic part, module.

While driving above 70 mph, the vehicle begins to have vibrations. Have taken our Suburban in for multiple repairs but their reasoning was the vehicle and tires were not balanced however after replacing the tires and getting a road forced balance it did not resolve the issue. It does not feel safe to drive above 70mph.

When traveling at interstate highway speeds vehicle had shaking, shimmying, vibration and buffeting as well as loud hum and wind noise causing nausea resulting in nausea and dizziness to the driver. This was worse on new macadam and on grooved highway but occurred intermittently on other surfaces, I just purchased this vehicle used and it is certified. I was unaware that this is a common issue and understand now that there is no recall to fix this and that gm has not found a permanent solution to the problem. The vehicle was also exhausting to drive on the highway because of the aforementioned issues.
