2017 GMC Acadia Suspension Problems

The rear knuckles have a casting defect that does not allow the lower most forward control arm bolt to be tightened fully. This causes the bolt to be 1/8” from being fully tightened. After removing the casting defect you are able to tighten the bolt fully. The bolt broke off in the knuckle causing the tire to point away from the body at a 45 degree angle. If my wife was on the interstate doing 60 when this happened it could have been life threatening but she was only doing about 10 when it snapped.

PERSISTENT GROANING AND CREAKING FROM FRONT END SUSPENSION. DEALER REPAIR SHOP COULD NOT DIAGNOSIS ISSUE HOWEVER THERE IS A REPAIR BULLETIN PUBLISHED ON THIS ISSUE AT GMREPAIRINSIGHTS.COM WHICH LEADS ME TO BELIEVE THIS IS A KNOWN DEFECT WITH THE SUSPENSION OF THIS CAR AND OTHER SIMILAR MODELS. THE DEFECT AS DESCRIBED IN THE REPAIR BULLETIN MAY LEAD TO MECHANICAL FAILURE OF IMPORTANT PART OF SUSPENSION WHICH COULD LEAD TO INJURIES OR HARM TO OTHER DRIVERS. I SCHEDULED A SERVICE APPOINTMENT ON 12.28.2022 AND THE DEALER COULD NOT IDENTIFY THE SOURCE OF THE PROBLEM.

SHIFT TO PARK PROBLEM, THE DEALER TRIED FIXING IT 3 TIMES NOW AND HAVING A PROBLEM WITH THE WHEEL. WHEN SOMETIMES TURNING THE CAR. I CAN FEEL SOMETHING IS LIKE STOCK ON TGE WHEEL MAKING ME FEEL LIKE THE WHEEL IS GONNA GET OFF. I TRUED CONTACTING THE DEALER AND CHEVY OFFICE FOR A BUYBACK BUT THEY AREN'T APPROVING IT COS THEY SAID I DONT HAVE ENOUGH REASON FOR THEM TO APPROVE IT. EVEN THO I KEEP TELLING THEM I AM NOT GONNA WAIT FOR ANYTHING BAD TO HAPPEN SINCE I HAVE A 5 MONTH OLD BABY WITH ME. TGE OBLY THING THEY SUGGESTING IS HAVING IT CHECKED. AND THAT'S IT.

WAS FOUND BRAKE FLUID IN THE BRAKE BOOSTER VACUUM HOSE AND BRAKE BOOSTER IS LEAKING FROM MASTER CYLINDER AND BEING DRAWN INTO THE BRAKE BOOSTER .

PLACED THE VEHICLE IN PARK, IT WAS STATIONARY AND IT ROLLED FORWARD. MESSAGE IN THE INFO CENTER SAID "SHIFT TO PARK". I WAS PARKING IN A MALL PARKING LOT.THIS HAS OCCURRED 5 TIMES. I CAN PUSH THE GEARSHIFT BACK AND FORTH AND THEN IT CAN BE TURNED OFF AND THE MESSAGE WILL DISAPPEAR. I TOOK IT TO THE DEALERSHIP AND WAS TOLD THEY ARE WAITING ON GM TO SEE WHAT CAN BE DONE. IT MAKES A SOUND WHEN IN MOTION AT SLOW SPEEDS ON A CITY STREET LIKE THE BACK NEEDS SHOCKS. IT SEEMS TO BOUNCE MORE THAN IT SHOULD.
