2015 Chevrolet Suburban: sudden loss of power

Filed Nov 26, 2025 · Steering · WI

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!

Vehicle was slipping and losing power. Vehicle was loosing power every time I slowed down on a traffic light and/or stop signs. Vehicle was taken to a local shop and it was determined that vehicle had serious transmission issues. Vehicle was then taken to Richard K Chevrolet. Their report (attached here) states “Found code for pressure control solenoid stuck on. Found large metal debris in fluid. Found transmission suffered mass internal failure. Recommend replacement”. Chevrolet will not take any responsibility for this massive failure and I ended up having to pay $5,500 to fix the issue (documents attached). I’m looking for Chevrolet to reimburse my expenses given that a vehicle just a bit over 100,000 miles underwent such a massive failure. My number is [XXX] .

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 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.

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.

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.
