Rear right hand lower suspension control arm broke in half, after further inspection it looks to have been separated from its original factory form which then cause uneven load on the arm causing it to fracture in half. The factory form separation seems to have been ongoing for unknown time due to surface rust is visible at the factory mold separation, where it snapped in half there is no surface rust. Fortunately it happened when I was only moving the vehicle to make space for another, the broken arm cause the wheel to turn to the right as if it was making a right hand turn and I can't imagine if it would have happened while driving in the city of even worse on the freeways. . . It would be a certain crash and safety for us and those driving around us. Last photo is from amazon listing, I did order the part from another source that is a factory gm part and I am doing the repairs of replacing this myself as I am mechanically inclined. Thanks.
On July 26, 2024, I was driving my 2018 Acadia, with my cruise control set to 48 in a 45 mhp zone. Nearing a bad curve, I sneezed. When this happened, I tapped the brakes to disengage the cruise control, my passengers side tires exited the road and with both hands on the wheel I tried to slowly bring my tires back to the road. However, I was unable to gain control and totaled the vehicle. A witness stated that she heard a loud pop coming from the vehicle before the wreck happened. I later learned from my insurance that the vehicle had a recall 17v516000 on it and I was never made aware of it. I believe that this was a factor in me not being able to control the vehicle.
Suspension did not meet yearly state inspection standards. Service advisor/technician stated “control arm bushing deteriorated- excessive play”. Rear control arms could be moved with hand pressure excessive play. They stated that this is a very common problem with this make of car at this mileage (41,633).
The toe links on my vehicle are bad and needs to be replaced. They broke as I was driving. Almost caused me to lose control and almost wreck. Thankfully there were no other cars around. I see this is a recall for GMC’s but for some reason not my VIN number. Not understanding why if I have the same problem on vehicles that were recalled.
Unknown.
