Electrical System Problems of Chevrolet Suburban - part 2

I recently took my 2023 Chevrolet Suburban in to make sure everything was working properly with the power train. . . It has been having bucking and stuttering between 15-45mph, which was super concerning to me, as I am transporting 3 children under 6 (one whom is autistic). I took in yesterday, and was called back today to confirm that the issue is happening. . . The problem is that instead of Chevrolet recalling these vehicles to have this computer issue taken care of. . . They did an update and are charging their clients to have this update done. This is a serious safety hazard, especially for families like mine that cannot afford to have this update done. I will likely have to drive around without having it done, all because of gm's greediness.

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.

While driving on the highway at 55 mph during a long-distance trip, the engine of my 2022 Chevrolet Suburban (6. 2l v8) failed suddenly without any warning lights, messages, or prior symptoms. The vehicle lost power unexpectedly, creating an extremely dangerous situation. I was traveling to a national wheelchair basketball tournament and had a passenger in the vehicle at the time. Our safety was immediately at risk due to the abrupt loss of power in a high-speed traffic environment. The vehicle was towed to the dealership, where the issue was confirmed as a complete engine failure. The dealership later replaced the engine under warranty. I was informed that the engine installed was the same model currently under active recall (n252494001), which affects the 6. 2l v8 engine in this vehicle type due to defective crankshaft or connecting rod components. The failed engine is no longer available for inspection, but the dealership should have records of the inspection and replacement. There were no warning lamps, error codes, or drivability issues prior to the failure. The malfunction was immediate and severe.

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 car turned itself off while driving 55 to 60 mph on a highway. Would not turn back on after getting to the side of the road. Very dangerous.

- truck makes a sizzling sound when parked - car wouldnt start and needed battery jump, unknown source draining the battery - truck has engine issues , started shaking and died in the middle of the highway, gm replaced engine - engine replaced after less than a week, truck would not start, gm replaced starter - after 2 days and using the vehicle once, truck would not start again. Gm is trying to root cause issue but cant find a resolution since the car stopped when we were on the highway and none of the fixes seem to be working I am worried that the car will abruptly stop again and put my life and others at risk.

The power steering on the vehicle had failed on December 10th, 2023. The sign was displayed on the dashboard for the vehicle. The vehicle was taken to sunrise chevy and stayed with them for a month for repair and they have been unable to repair the issue. They said the rack and pinion had gone bad on this brand new car. This is very dangerous as the safety of myself as well as others on the road are compromised due to faulty steering problems.

The contact owns a 2021 Chevrolet Suburban. The contact stated while driving 45-55 mph, the vehicle lost motive power inadvertently. There was no warning light illuminated. The contact was able to veer to the side of the road. The vehicle failed to restart and was towed to the dealer, where it was diagnosed that the fuel pump power control module had failed and needed to be replaced. Additionally, the dealer informed the contact that the battery needed to be replaced. The contact related the failure to NHTSA campaign number: 21v739000 (fuel system, gasoline); however, the dealer informed the contact that the VIN was not included. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 90,000.

While driving on the highway at night during rainy conditions the wipers stopped in the up position, and at the same time, the headlights turned off. After a few seconds they resumed normal operation. My headlights were in the auto position and my wipers were also in the automatic setting. Being as that I was on a highway at night, in the rain, and going approximately 65mph surrounded by traffic, this was an extremely dangerous situation to be in. Without headlights and windshield wipers, my windshield was immediately obstructed and I was unable to see the road without headlights. More so, other traffic might have had trouble seeing my vehicle. This problem has not been replicated by myself or a dealer. It has been random in nature. When the incident happened, there were no warning lights on the gauge cluster or anything else inside the vehicle that seemed to be affected.

While driving the vehicle on an extended road trip trip on the interstate the vehicle randomly shut off while driving at highway speeds. When the vehicle turned off all interior and exterior lights did not work. The engine turned off. In order to begin driving again the vehicle needed to be restarted. This issue happened 3 separate times. In between, the vehicle has been turned off. It is a safety issue to have your vehicle turn off randomly while driving at any speed. The issue has not been reproduced by the dealer. The vehicle has been seen by the dealer and stated "they are unable to find any issue" there was not indication before or after the 3 events that would indicate issue.

We have suddenly experienced a problem with our 2019 Suburban, seemingly identical to a problem that plagued 2015 gm light trucks and suvs (NHTSA campaign number: 18v586. Gm's own number for this recall is 18289). At low speeds (typically parking lots, under 5 mph), when turning, we intermittenly lose power steering. This is more common when switching directions rapidly such as during a parking maneuver. Simultaneously, headlights and interior lights intermittenly dim. The instrument cluster screen will display random warning messages (“roll window down then up”, etc). The clock time resets as though the battery was disconnected. Our 2019 Suburban has only 68,000 miles and has received all scheduled maintenance. The battery was recently replaced in September 2022 (14 months ago). I have inspected the wiring and found nothing lose.

My 2007 Suburban has extensive rust that has left the frame open and crumbling. It appears that the seals on the vehicle did not do their job. The spare tire cannot hold under it. I have never taken it into salt water nor has it had flood damage. Its main years on the road were in CT and NJ. I have never seen a vehicle with this amount of crumbling rust. I have to drive 2 hours each way to see my specialists at shands hospital in gainesville every 2 - 3 months and as a female it does concern me that there is that lifter clicking as well as the oil disappears and yet there's no puddle. Also, the lighting in the cabin ac area doesn't function as well as the rear controls. In florida my last two problems deal with my problem with heat. The a/c runs intermittently and sometimes only blows very hot air. Also, what a big reason I purchased a tahoe ltz and this vehicle was because of the remote start which is not working. Is there anything that can be done. I needed a safe vehicle for my short regular trips and I've become worried and I have already had to rent a vehicle to make the trip out of fear of the cabin getting so hot. With narcolepsy I can fall asleep without warning. Please advise. I'd love to keep the truck but not if it could mean injuring someone else or myself. Thanks in advance.

While slowing down to make a left hand turn at an intersection, my vehicle suddenly lost power steering and the entire system completely shut down. There was no electronic function during that time. I had to put the vehicle in park, turn the key to the off position and then start it back up. It has happened multiple times, both at low speeds in drive and reverse. This would have caused a collision if there was oncoming traffic at the intersection at that time.

Stopped at a stop sign. The vehicle suddenly lost all electrical power. Lights began flashing. Traction control system turned off and on. Then it went back to normal driving. I just had the chassis control module recall taken care of as well. The air conditioning is intermittently cutting its ability to cool then suddenly cooling again during this time. When the vehicle turned back on, the strong odor of fuel was present from the air vents. I had reported the issue before but was told by a dealer there is nothing wrong they could see beyond a visual inspection.

There were no accidents or near accidents but the computer system was spitting out different problems and telling me that different system were needing service such as the esc system, the steering wheel column l, collision traction , etc plus the engine light came on. Thus occurred on the 20th of June. I took it in for service and they said they fixed the problem but then while coming home on the 22nd the system started acting up again. Took it back to the dealership and they said the computer lost communication. They had to keep my vehicle because they cannot figure out jow to adjust the computer harness and why I am continuing to get the error codes. This vehicle is only 4 months old (3/11/23). I am concerned that could be a major problem if it cannot be fixed.

Despite replacing throttle body and accelerator pedal position sensor, I continue to have my Suburban go into reduced engine power without much warning. It is very dangerous when you are driving on the freeway and your vehicle suddenly will not do over 35mph with the engine revving to 4000+ rpm. I've spent nearly $1000 at repair shops and have found that nothing they attempt will fix the problem. I cannot trust vehicle with my wife and kids riding any distance in it.

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

On star module failure. The module controls many different safety features and it has failed and has been on a backorder for months creating a safety issue every day.

I have a 2008 Suburban. Beginning in August, there was an accident on the highway and traffic was backed up. I was idling, waiting for the traffic to move, like every other car on the hightway and the Suburban just shut off and said "stablitrak off. " it happened numerous times after this, just when idling. I took to the dealership I bought it at. They charged a ton to fix something but it didn't' take care of the problem. It's gotten so much worse. I took back a few months ago and they fixed it again, but didn't charge us this time. Now it's so much worse. Anytime I'm iding, just picking my daughter up at school or just stopped at a red light, a warning comes across, "service stabilitrak" or "stablitrak off. " and the car immediately shuts off. It usually restarts in 5 minutes or so and I can usually make it to my destination as long as I don't idle again. Monday I was picking up my daughter and it stalled in the parking lot at her high school with tons of cars behind me- I waited, restarted it as I have done in the past. But then, going down this steep high school hill, the car shut off, lost steering and brakes wouldn't even work. I had teen drivers ahead of me that I nearly crashed into, teens in my car. This is not ok. We took it back to the dealership and now they say it's an electrical problem. I've read a ton online forums that this is something that happens with a lot of other people. I'm afraid to drive my car. I'm also not sure what to get fixed because these other people have spent tons of money, just like me with no results.

My car shut off two times while driving. When you google the issue, it auto populates meaning that this is a very common issue with gm. It starts back to 2015 searches as well. Gm needs to recall their Suburbans for their cars turning off while driving which caused me to lose power steering, power brakes and anything that requires electrical.

It was diagnosed as the telecommunication module, this part malfunctioned causing issues with audio in the vehicle. The audio would at times play normal, at times go completely out losing all sound to turn signals, hazard signals, and safety sensor audios inside the vehicle. It would additionally lose communication between the key fob and the unit causing warnings during driving and non-start issues. With that said, the lose of audio when expecting safety sensor sounds, or sudden audio on complete full volume with the only resolution being to shut the car off is a safety issue. The vehicle had to be pulled over on the travel portion of the highway to resolve the sound issues on multiple occasions. Software updates, radio head change didn’t matter, until it was diagnosed as the module described above. Occurrences were completely random.

While driving the vehicle lost all power and after about 20 seconds power came back on. The repair was the battery cables which was apparently very common on the make and model of vehicle. It's unsafe and can cause an accident and apparently happens on the majority of vehicles same year and make.

Side detection module smoking causing dash malfunction and electrical issues.

Service safety restraint constantly reappears. Taken into dealership 3 times and still has not been fixed. This could cause serious injury or harm and I have 4 children 10 and younger. This has been an on going problem.

Purchased my 2016 Suburban on 1/14/23 and since it has been “service trailer brake” distracting me from driving . The service chime stops me from listening to music , my turn signals , constantly making me look down . I drove around in total for 4 hours throughout my day and non stop. I’ve contacted the dealership and told me to wait till the end of the week.

The electrical system has gone out completely comes back a few seconds later with different icons saying to roll driver side window down then up, or stabiltrax. It has also caused complete electrical failure being on a road while driving. This has also cause my wheel to jerk taking out the power steering and the engine has shut off completely to the point where I have to wait a few minutes to even turn it on. This has happened while reversing in to a parking spot and the whole car dies. It kills power so much that I have no hazard lights. When I’m able to get it to come back on it’s like it reset its self. I have taken it to the shop and they have said the battery cables and the mega fuse above the battery. I know this is a known issue in other like vehicles.

The vehicle will just stop operating while driving. This past Sunday, December 18, 2022, I was driving to the tampa bay buccaneers game and turning into the parking lot and the vehicle just stopped operating, completely turned off. Couldn't turn steering wheel, put into neutral or anything. Police assisted me as I was blocking the main road to the parking lot. No electrical in the vehicle. This happened a few times before but the car would usually restart quickly. This time it sat for over 5 minutes and then for some reason I was able to get it restarted. There is a service bulletin for this issue from Chevrolet TSB pit5405, however there are no parts available for this fix. This is a very dangerous situation as this happened in the middle of a major road and could happen at anytime without any warning. Luckily no one has been hurt or any accident but it is scary to say the least.

Car has been at dealer 3 times for WI-fi issue. Mechanic took car home for longer drive to check. No found issues. Brought in for small noise that comes and goes. They came back saying $10000 for cam shaft and lifters they are assuming.

Trailer brake system service message took it to the dealer service department and was told that a diagnostic would be needed to find problem $225, if the wiring harness is indeed defective it would be over $500 in parts and $600 in labor. A picture of the light coming on while driving was produced to the dealer service department. It first appear when driving on the freeway and we have never towed anything with this vehicle. Upon further online research we found out that this is a common and serious problem with GMC and chevy vehicles like the canyon, sierra, silverado, yukon, tahoe, Suburban, colorado from years 2015-2020.

When I started up the vehicle with the key fab button I noticed the cabin air blower came on as normal however when we went to the cockpit we noticed the engine was not running. When we went to start the vehicle (holding break and pressing start button) the dashboard started the z71 launch sequence and then went to a dashboard as if I was in the normal drive mode however the dashboard was extremely dimly lit as if the backlight was not on and the engine still was not running. After several attempts to start using the brake+start button method we noticed a clicking sound that seemed to be coming from the engine cabin just in front of the passenger cabin however it would never ignite/start the engine. After several attempts to start the engine through the brake+button, we tried to just press the start button, which would sometimes be prompted on the dashboard, and get some feedback from the dashboard through better backlighting and messages I now cannot recall but never ignited the engine. When we tried again with the key fab x2 button (hoping it would either start or "cancel" the current vehicle state), we received no response from the vehicle. When we attempted to shift, it stated the "conditions were not met", which I perceived as the correct response. The vehicle was stuck in this "mode" with the air blower still running and exterior lights still on and it was only a matter of time until the battery ran out. When it ran out later that day (though not completely ded) in rebooted in the same tweener mode. However, when we came the next day with a tow truck and a fully dead battery in the Suburban, the vehicle booted right up as normal. The tow truck driver indicated several new tahoe drivers experiencing the same issue. To me, this is a software launch issue. While the vehicle was not perceived to be in danger, it left us stranded in what could be a dangerous location. Several episodes as reported by tow truck. Unsure if inspected. No symptoms before problem.

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.
