2016 GMC YUKON XL Steering Problems

I was test driving the vehicle after some and as I was test, driving it, the steering lot up on me. Luckily, I was entering a residential area when it occurred down the street from my residency; in which I was able to drive it to my residency, during that short ride, you could smell a burning smell coming out along with some crackling noises. I had to get the vehicle towed a week later to the mechanic shop where they fix one of my engine problems and verified that I needed a new power steering unit and gave me a quote, I couldn’t afford the word and started doing research and came across the recall for the power steering within my vehicle year, make and model. I replaced the power steering unit, but I’m having a difficult time celebrating the system..

While driving vehicle the vehicle appears to shut off as if someone is turning off the ignition. The steering control becomes stiff, power is lost and electronics flash and turn off and on. This has happened on multiple occasions and is intermittent during acceleration. The accessible grounds have been checked, battery checked and replaced, and alternator checked and verified to be charging appropriately. Several codes are present and have been cleared to return indicating low voltage issues with multiple systems.

Loses power randomly. More prominent at low speeds and turns. Has lost power going down the road, will turn back on. Stabilitrak lights and jerking steering wheel are more common. Will not always start right back up when it shuts all the way off/loses power. Loses clock but keeps radio stations. Had it scanned. Asked dealer about issues/recalls and information with nothing more than “this is not common” and “we need to schedule a time for you to bring it in”. Times were not soon and they made it seem like it is not an urgent/emergent situation. Would not agree to me being able to talk with a tech. Looked into this as it seems common but nothing definite. Bad battery cables seem prominent, grounding issues, electronic steering module, and a few others. Seems like a GM problem that is known but not being handled. Greatly disappointed after reading up...

POWER STEERING LOSES POWER TEMPORARILY, POWER GOES OFF AND COME BACK ON WHEN I'M COMING TO A STOP AND MAKING A SLOW TURN

VEHICLE SHAKES/VIBRATES ABOVE 35 MPH. WHEN VEHICLE ACCELERATES ABOVE 35 MPH THE THE STEERING WILL VIBRATE WITH A FEELING THAT THE SUSPENSION IS SHIMMYING/SHUDDERING RAPIDLY. THIS IS ESPECIALLY BAD ON AN INCLINE FROM A STOPPED POSITION. AS THE VEHICLE ACCELERATES UP THE INCLINE, WHEN APPROXIMATELY 35 MPH IS ATTAINED, THE ENTIRE VEHICLE WILL STEADILY SHUDDER/VIBRATE. TRAVELING AT HIGHWAY SPEEDS THE VEHICLE WILL RANDOMLY VIBRATE IN THE FRONT END AND IN THE STEERING WHEEL. THIS OCCURS WITH BRAND NEW TIRES THAT HAVE BEEN BALANCED AND RE-BALANCED TO CONFIRM IT IS NOT TIRE RELATED.

THE TRANSMISSION WENT OUT, THE ENGINE IS MAKING A NOISE AND A SERVICE CENTER SAID LOTS OF GM'S VEHICLES ARE HAVING THE SAME PROBLEM THE POWER STEERING SYSTEM ALSO STOP WORKING AND I HAVE TO REPLACE IT

AT 64,497 MY WIFE'S POWER STEERING WENT OUT ON HER VEHICLE. THIS HAPPENED A DAY AFTER OUR TRIP TO ATLANTA, GA. WE TOOK IT TO OUR LOCAL GMC DEALERSHIP AND WAS NOTIFIED THAT 4 MODULES HAD TO BE REPLACED AND A RECOMMENDED WIRING HARNESS. IN 2015 GMC VEHICLES HAD A SIMILAR ISSUE AND RECALL BUT NOT THE 2016. THIS COST ME $1400 IN REPAIRS.

EXCESSIVE VIBRATION/BUFFETING DRONE ISSUES (AT ALL SPEEDS OF THE VEHICLE) HAVE CAUSED SEVERE HEALTH ISSUES AND SAFETY HAZARDS FROM DRIVING THE VEHICLE. WITHIN THE FIRST 8,000 MILES OF OWNING THE CAR, THE CAR HAS NOW BEEN IN SERVICE FOR 40 DAYS AS GM TRIES AND REMEDY THE PROBLEM, BUT THERE DOES NOT APPEAR TO BE A FIX. SO FAR, DIAGNOSTIC TESTS INDICATED THAT THERE WAS A FAULTY BEARING IN THE REAR DIFFERENTIAL THAT LED TO SIGNIFICANT ABNORMAL WEAR THROUGHOUT THE DIFFERENTIAL AND THE DIFFERENTIAL NEEDED TO BE REBUILT. WHEN REBUILDING, THEY DISCOVERED THAT THE DISASSEMBLED DIFFERENTIAL HAD HEAVILY SCORED BEARINGS AND METAL SHAVING THROUGHOUT EVERY BEARING. RING GEAR AND PINION HAD IRREGULAR WEAR CAUSING A DRONE IN THE VEHICLE. RACE SURFACES WEAR GROUND AND SCARRED BAD.THE REBUILT DIFFERENTIAL DID NOT FIX THE ISSUE AND NOW AFTER HAVING FOUR NEW TIRES AND ROAD BALANCING, THE PROBLEMS DIDN'T DIMINISH BUT WERE EXACERBATED....
