On 02/12/2020, i was turning turning to park in a parking spot at work when the radio and other electrical components shut down, and the steering wheel jerked in the opposite direction. i temporarily loss control of my own steering wheel. this occurred 3 times while trying to park. in addition, a message about stabilitrack appeared. it is well known that gm has recalled over 1,700,000 vehicles with this same power steering issue stating that owners will lose control of the steering wheel, increasing the risk of a crash. see nhtsa campaign number: 18v586. gm's own number for this recall is 18289. however, gm has only included certain vehicles in this recall, mainly 2014 and 2015. my 2016 gmc sierra 1500 is currently not included in gm's recall even though the same power steering problem is occurring. according to a notice published with the nhtsc, the trucks may experience a temporary loss of electric power steering (eps) assist followed by a sudden return of eps assist. the issue, gm says, occurs typically during low-speed turning maneuvers. if eps assist is lost and suddenly returned, the driver could lose temporary control of the steering wheel, increasing the risk of a crash. gm says it first became aware of the issue in feb. 2017 after receiving customer complaints related to loss of eps. tests conducted between april and may found that some of the vehicles contained electrical issues that could cause loss of eps. the carmaker was to contact affected owners & dealers will perform a reflash of the eps module software. gm stated that newer vehicles contained recalibrated software and will not have this issue. gm is incorrect in it assessment since i have just experienced the same power steering issue in my 2016 sierra, & now the dealer does not want to repair the issue since there is no gm recall on 2016s. there is definitely a problem with power steering on 2016s.
I was waiting on the oncoming traffic so i could make a left turn. i had plenty of time to make my left turn in front of oncoming traffic, as i proceeded to make my turn all if a sudden my steering wheel locked up, stability trac light came on, my power locks locked and unlocked intermittently and truck engine died. i had to restart engine and it did it again as i was moving attempting to finish my turn. this happens on a regular basis now anytime i have to turn steering wheel it locks up and does this. sometimes it does everything i stated above but engine doesn't die. this is dangerous. a couple times when it does this my truck doesn't have any power to start but wait 30 seconds to a minute, power will restore and you can then start it up. it almost sounds exactly what is happening that the 2015 gmc 1500 are being recalled. this happens now on a daily basis.
Periodically 3 times a week, while driving, the stabiliztrak illuminates and drivability declines, engine check light illums, the gear remains in a low gear without shifting. turn the ignition off for a couple seconds and it clears and the engine light goes out after 25-35 miles. sometime it doesn't reset after 3 attempts of turning off and on the ignition. the codes are p0700 a u0100 with others when dealership analyzed. three times it was in the gmc shop and three times giving back and problem still existed. i recorded on video and gave it to the dealership as proof.
