2017 GMC SIERRA 1500 Complaints

AT APPROXIMATELY 98,000 MILES, THE DASHBOARD ERROR MENU NOTICE TO SERVICE THE POWER STEERING SYSTEM. THIS VEHICLE HAS ELECTRONIC POWER STEERING. WHILE REVERSING AT LOW SPEED, THE POWER STEERING FAILED. I STOPPED THE TRUCK, TURNED OFF THE ENGINE, WAITED 15 SECONDS, AND RESTARTED THE TRUCK. THE ERROR NOTICE REAPPEARED AND STEERING POWER RETURNED AFTER ABOUT 15 SECONDS. DURING THAT 15 SECONDS THE STEERING WHEEL APPEARED TO OSCILLATE SLOWLY ABOUT AN INCH, THEN STOPPED. STEERING HAS BEEN NORMAL SINCE, THOUGH THE ERROR MESSAGE STILL APPEARS. I KNOW 2015 MODELS HAVE BEEN RECALLED FOR THIS SAME ERROR. I BELIEVE THE RECALL SHOULD BE EXPANDED.

While driving the power steering goes off intermittently during a low speed turn either right or left. The dash goes dark and then the steering assist warning comes on or the trailer control light comes on. This looks to be the same issue that’s recall was issued for the year 2015.

My truck is currently experiencing the connecting rod and/or crankshaft engine components that may have manufacturing defects that has lead to engine damage and engine failure. My truck is currently being looked at a shop for this exact issue. GM recently recalled more than 597,000 vehicles due to engine failures, according to you, the National Highway Traffic Safety Administration. The recall however only lists vehicles within the years of 2021-2024. My vehicle has the same engine 6.2L V8 gas as the recall and I don't find it a coincidence that I have the same EXACT engine experiencing the same EXACT issue! I attempted to speak to GM but they just kept saying my vehicle is not listed on the recall and refuse to investigate this. I included my conversation with them.

I had to replace my transmission at 71902 miles. I complained to Flow GMC dealership over seven times about the Vibration , jerking, shaking and shuddering. Most of the time when I carried they said they can not duplicate the problem. On Feb. 05, 2025 I was driving and stopped at a stop light when I pulled off the vehicle started vibrating, shaking and had a hard jerk. I thought someone had ran in the back of me but that was not the case . I had it pulled in to Flow GMC they checked it out and said the transmission need to be replaced. I had it replaced at the dealership. I had to pay $7782 to get a new transmission. I read were they being are all on some GMC models. I want to know why the 2017 GMC has not been recalled.

Total loss of power while in motion on highway going 70 when first happened, got video of problem for shop while going lower speeds. Truck will loose all power the dash will turn off and then turn back on sometimes the engine will cut out completely.

When shifting down to a low gear at an abrupt stop the transmission will hit hard causing vehicle to brake harder and has almost gotten in accidents because it seems to push itself a bit.

Vehicle went into limp mode. 36 check engine codes popped up all related to cam shaft and lifter issues. Vehicle was taken to a shop and it has been determined that the passenger side lifters and rollers have sized due to the active fuel management system. This is the L86 GM 6.2 liter motor, that has developed the same issues that the L87 motor is being investigated for. There where no tail tail signs or check engine lights that were on prior the the lifter failure.

first we had coil issues then it turned out to be the lifters now we are being told we need a new 6.2l v8 engine.

Original issue started at about 60K miles regarding hard shifts and clunking with acceleration with my 2017 Sierra 6 speed transmission. I had it inspected by the dealer when I purchased it, told it was normal for this model. Had it inspected by independent shops, told that this is a known issue, but not fixable without a new transmission. At 90K miles, began experiencing a whining sound while idling. Told it is in the torque converter/transmission housing but I could not afford the thousands of dollars for replacement/inspection. I had the transmission fluid serviced and changed as recommended with the dextran ATF that GM recommends in the manual both at 60K miles, and again at 100K miles as recommended. I also drive the vehicle reasonably, yet still at 130K miles had the transmission and converter fail. With no warning, no check engine lights or vehicle codes. Even after I lost 5th and 6th gear, there were no warnings or alert in my truck and despite the transmission giving out while on the highway. I feel this is a huge safety concern with both GM torque converter and transmission issues being known, as well as my vehicle not giving any warnings before, during, or after my transmission failing. I have had the warning lights checked as well, I’m told they are fully functioning when tested, so for some reason there seems to be an inherent issue with the truck’s warning system.

Rear defroster failure. The rear defroster was turned on causing smoke to appear from the power sliding rear window, then the rear window shattered causing glass to fly into the backseat and truck bed.
