2019 GMC Sierra 1500: loss of power steering

Filed Aug 21, 2026 · Suspension · MD

Several months ago while having my truck serviced, I asked the repair shop to inspect the ball joints on the passenger side because they would make a popping noise when turning the wheel. The shop inspected them and said that was a normal sound due tot he factory lift. Recently I was driving home and about to turn into my lane when the front passenger wheel assembly collapsed under the truck due to the a upper ball joint failure separating the brake line and loss of steering. At the time, I was only going about 25mph and the truck slid to a stop on its own. The truck has 65,000 miles on it and if this had happen at highway speeds personal injury to myself and others would have been likely. The repair cost were $7,500. Fortunately I purchased an extended warranty which covered all but $1,700 of the repair.

On XXX at approximately 3:00 p.m., I was driving on the highway in [XXX], at approximately 65 mph when my truck suddenly displayed a warning stating that all oil pressure had been lost and that the engine needed to be shut off immediately. Within roughly seven seconds of seeing and comprehending the warning, I attempted to safely shut down the engine. Before I could do so, the engine seized while the truck was still traveling at highway speed.The engine failure caused an immediate loss of power steering and power-assisted braking, leaving me with limited control as the truck coasted at highway speed. This was an extremely dangerous situation that could have resulted in a serious accident, injury, or loss of life. The truck was towed to a repair facility, where technicians confirmed that the engine had seized and recommended replacing the long block. A new GM Genuine Parts engine was installed, and the repairs were completed on XXX. Today, XXX, the replacement engine has approximately 40,000 miles on it. I recently began hearing a ticking noise followed by knocking, and the engine nearly stalled while idling. I immediately checked the oil and confirmed that oil was present on the dipstick. I have consistently maintained the vehicle and completed every oil change at intervals of 5,000 miles or fewer. I returned the truck to the same repair facility that installed the replacement engine and was immediately informed that the truck requires yet another engine replacement. This is now the second 6.2L L87 engine that has failed in this vehicle. Two catastrophic engine failures—one involving a replacement GM Genuine Parts engine after only approximately 40,000 miles—are completely unacceptable. The first failure created a severe highway safety hazard, and the failure of the replacement engine raises serious concerns about the reliability and safety of these engines.

Power Steering failure. Loss of power steering while driving the vehicle made any turns nearly impossible. Dealership identified root cause and a problem with a grounding strap. They reported that in addition to our vehicle, another GMC Sierra 1500 had come in the same day with the same problem. Loss of power steering while driving can lead to collision. This should be a safety recall.

This is a second report of an issue that first happened in February 2025, the dealer replaced the battery and called it fixed. On Friday 5-2-2025 I started the vehicle and as I was driving the dash lit up with these warnings: Service Trailer brake system, Service ESC, Brake System Failure 62 mph top speed, Steering assist reduced drive with care, The vehicle steering got stiff and brake pedal went to the floor board with a little braking available if I stood very hard on the brake pedal. I got off to the side of the road, cycled the truck on and off and was able to drive off. It did this three times before I could get it to the dealer the next day, If my daughter was driving I would have expected that two of the three would have resulted in a wreck as she would not have been strong enough to steer or stop the vehicle. The dealer had it three days and replaced the brake master cylinder and called it fixed, I picked the vehicle up and on the way home I stopped for gas, after the gas station the dash displayed: Service brake assist, I turned right around and took it back to the dealer, they checked the code and said the brake assist module was drawing too much current, I picked the vehicle back up three days later, they said they bleed the air out of the brake system and called it fixed. No one wants to ride with me and my daughter is begging me to trade the truck, they call it a death trap waiting to happen. GM says it is all normal issues.

Loss of steering multiple times. Very dangerous to try and drive. GMC says shut off vehicle for 20 minutes and try again. Once it worked otherwise it continued to lose power steering, either driving or turning on. I have went into GMC forums and found out there are thousands more people that this has happened to. Thank you for what you people do.

Service power steering warning appears on dash and all power steering is lost. First time the power steering went out I was driving over railroad tracks. The second and third time the power steering went out it was mid turn and it force my truck off the road because I didn't expect it to happen.

My pickup started, I pulled out on road and sped up to 35 MPH, when I stepped on brakes to slow down they were unresponsive, so I began pumping. They felt very hard to pump and were not slowing the truck down. Lights came on saying service brakes etc. As I coasted to try to slow down off side of road. I had to keep pumping the brakes down to floorboard and I?m not sure they were even working. I lost power steering and was almost involved in a serious rear-end collision. 4 messages appeared on digital dash while driving. Service ESC, brake system failure 62 MPH top speed, service trailer brake system, steering assist reduced. I had to press brake pedal to the floor with extremely excessive force to get truck to stop. This failure could have easily resulted in vehicle accident, or even a fatality accident. I doubt I will ever carry my family in the truck again due to this and I certainly will not allow my children to drive the truck. This is the 5th time this has happened to my truck.

I started my car and I had 4 messages appear on the dash stating(service ESC, service trailer brake, brake system failure-62 MPH top speed and steering assist reduced drive with care). I attempted to drive the vehicle in my neighborhood and noticed that I had lost power steering and when I went to brake there was a delayed response. It took the vehicle approximately 4 to 5 feet to come to a stop after braking. Also the ABS, check engine, brake and traction control lights were illuminated. I immediately tried to drive back home and when I drove in to my driveway, I smashed on the brakes and I almost drove through my garage because the vehicle would not stop immediately. I tried to press my onstar button for road assistance and lost all electrical power. I contacted onstar with my phone and had the vehicle towed to the dealership where I purchased the vehicle. Currently the vehicle is there being diagnosed for the problem.

Electronic power steering went out when taking an off ramp, transitioning from a cruising speed of 65 MPH. Very difficult to navigate the turn and could have easily resulted in an accident if it had occurred in a heavy traffic situation or in adverse weather conditions. Turned the vehicle off, sat for 15 minutes, started and the condition was gone. Took vehicle straight to dealer for repairs.
