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.

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.

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.

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.

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

Side detection module smoking causing dash malfunction and electrical issues.

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.

Trailer brake system continuous alerts.

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.

When turning at speeds below 20 mph, motor stops lights go out, lights and gauges will come back on and car can be started. This has happened two or three times over the last three months but now only five days apart.

The service trailer brake system keeps popping up. Keeps dinging off and on whether you push the dismiss button or not. When this is on I question if the electrical brakes will work when I tow our camper. It is very distracting while driving. Safety concern for sure!.

The service trailer brake system error keeps coming up on my vehicle.

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.

Driving today in snow, increased electrical demand on vehicle while accelerating. Smelled burning wires and all dash lights flickered then died. Engine turned off and had to be restarted with the push button. Happened within 30 minutes later while accelerating onto a main road with traffic, lost control of vehicle and had to force the steering wheel to turn the vehicle off the road to avoid being hit by oncoming traffic.

Vehicle sensors and warning lights illuminated while the car was in motion on the highway. Pulled car off at nearest exit and turned ignition off. Could not re-start vehicle for 10 min. Finally car started, drove it to dealer, they said it was a loose ground cable & tightened connection. 3 months later vehicle caught fire while in motion going 25mph on street. Burned cables coming off battery terminal. Gm ceased investigation due to the battery in vehicle was not the original factory battery.

Vehicle safety features / starting sets uncontrollably shaking, and warning crash started alerting randomly. Had extended warranty but noticed others had the same issue. Feel like a deductible should not have been applied to have this repaired as it is a safety feature on the vehicle.

Blind spot detection modules are bad, vehicle will not detect object in blind spots.

The system that is failing is on my Suburban is the trailer break system, yes it is available for inspection. The continuous alert is distracting to the point of the vehicle being un-drivable and without the trailer break system functioning properly it puts people in danger due to not being able to safely stop while towing. The dealership said they were unable to reproduce the code. The vehicle has not been inspected by anyone except the dealership. Yes, both a visual and audible alert pops up continuously with a loud “ding” and a “service trailer break system” warning.

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,.

Loss of gps, onstar, xm and compass function. Water has leaked into the roof mounted shark-fin antenna. Vehicle has lost compass, gps, onstar and xm capabilities. Dealer recommends replacing roof mounted antenna. Despite this being a known problem acknowledged by Chevrolet in sb-10058785-9942 this VIN was not included and customer will be charged out of pocket for antenna replacement.

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). .

The 2015 Chevrolet Suburban that I drive power goes out when I am turning into a parking space, making a sharp turn, and try to come to a quick stop. This happens every time I am driving. It also delays to turn off when I am parked. It sounds like it's trying to crank up on a low gas level. Sometimes when I am at a light and try to press on the gas, it stalls like it's trying to get gas.

My vehicle loses all electrical power randomly while driving after taking it to the dealer for the powersteering recall it is very dangerous especially when it loses all power on the highway keeps happening at random.

On several occasion the touch screen display has failed to turn on. This screen is used for the display of the backup camera, the audio, hvac, and other controls. This has typically happened when the vehicle was first started, though it has happened while the vehicle was in motion. At wich point the display remains blank and my not work untill after shutting down the vehicle and restarting it again. This is an intermittent problem.

While driving at speed with cruise control on all lights flicker and when activating a turn signal power flashes shutting down cruise control and all accessories (dvd player, radio, etc. . ). Also loss of power steering. Randomly while driving also get service stablitrak and park assist warnings.

I received a recall notification from chevy (recall number 18289) and my vehicle had occasionally experienced some of the listed problems in the recall so I immediately took my car in to be serviced. After the the recall service my car seemed to be fixed, but that only lasted a few days. The problem is back and even worse than before. When turning the steering wheel at low speeds the my car experiences temporary loss of power, the entire electrical system shorts out briefly (radio, display screen, power locks all turn off/on) and the wheel becomes difficult to turn. Since having the recall problem "fixed", in addition to the above still happening, the wheel just loses power steering (very difficult to turn) or locks up without electrical loss and on two separate occasions all of the above has happened and my care stalls mid turn and I have to put my car in park to restart it. I have taken it to the dealer and they want to charge me to diagnose and fix any problems. I have also placed a call to Chevrolet and am waiting on a response. I am concerned and hesitant to drive my vehicle with this safety issue still occurring.

Roof mounted "shark fin " antenna leaks and resulted in short circuit of the electrical controls disabling the Suburban. Second time in 2. 5yrs the antenna had to be replaced.

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.

A/c has been out for over 2 years. Bought this piece of crap in 2016 and a/c has only worked for 1 year. Can not afford repairs due to having 2 kids in college and still trying to live in CA. I have a 2009 Dodge durango that works perfectly!!!!! a/c had never given me any problems. Called Chevrolet several times to have this fixed and no help at all from the dealer!!! will never buy a Chevrolet again in my life!!!!!.

When turning into parking lot today at low speed, electrical system went crazy, screen flashed power steering failure, stabilitrac failure, doors locked and unlocked and engine died. Restarted and was fine driving forward and repeated failures again when turning to park in parking space. It is fortunate this was in a parking lot and not on interstate or other main road or while turning at a traffic light.

Onstar gps failed to locate my vehicle when reporting an accident I was involved in 5/4/2018. The gps antenna is the failing component. This has been identified in gm service bulletin 15155. Under this bulletin owners where supposed to be notified of the issue, I was not. Gm will not honor the repair because the bulletin expired. If this accident was major and I had not been able to relay my location emergency services would not have been able to render care. The failure of this safety product and monitoring service should be corrected by gm.
