What owners report
The contact owns a 2018 Cadillac ATS. The contact stated while driving at undisclosed speeds, there was an abnormal growling sound coming from the vehicle. The contact looked underneath the vehicle, checked the tires, and checked the inside of the vehicle but found no failure. The contact continued to drive the vehicle and heard an abnormal winding or rubber sound. There were no warning lights illuminated. The vehicle was towed to the local dealer, where it was diagnosed and determined that the differential needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was approximately 84,000.
The vehicle has suffered a severe mechanical failure of the rear differential assembly, rendering it completely undrivable. This mechanical failure is a direct result of a known manufacturer defect documented in General Motors Technical Service Bulletin PIP5898/PIP5898B, regarding misoriented factory side bearing retaining snap rings that block internal oil ports, leading to fluid leaks, severe fluid starvation, and eventual component seizure. The component failure poses an extreme safety hazard to myself and other motorist. When a rear differential suffers catastrophic failure, this is known to cause the rear wheels and tires to lock up completely while driving leading to immediate loss of vehicle control, skidding, and high risk of high speed rear-end or rollover crash. …
1. The transmission shudders at high speeds and at low speeds it either hesitates to shift gears or it lurches forward causing a rough shifting of gears. 2. I feel as though when I am braking and my car lurches forward, sometimes I have to brake even harder just to get the car to stop in time. This has caused me to almost hit pedestrians and/or other car. At high speeds, when the transmission shudders, I feel as though I have to slow down in order to stop the aggressive shaking, making others driving behind me have to slow down. 3. A former family mechanic has tried to resolve the transmission issue for me and he was unsuccessful in doing so. I have not taken it to a dealer or a big name mechanic. 4. The vehicle has not been inspected by insurance, police or the manufacturer. Only a family mechanic. 5. …
Transmission causes car to shudder or shake/vibrate at lower speeds and lower rpm (auto shifting) It's been like this since it was purchased. If you perform manual shifting at 2500 RPM's or higher you don't experience the same shake/vibration. Ron Craft Cadillac says it's performing as expected.
I've only had this vehicle for about 2 years now. I purchased it off of Carvana and had 30 days I could've returned the vehicle if there was issues. When I first got it, I noticed the vehicles gas pedal would shutter a tad while going up a hill or at a higher speed like on the highway. It would also jolt a little while taking off but when I took it to the dealership they were saying everything is normal and I believed everything was fine since there was no lights on the dash, it was my first time ever buying a car myself, and I had no reason not to trust them. The vehicle is now at a little less than 85,000 miles and I can't drive it because of how bad it's jerking, I did a little more research and come to find out this is a huge issue with GMs vehicles transmissions within that years range however my vehicle in particular isn't on that list. …
Transmission drags. When stopping the car jerks bad and sometimes proceeds to accelerate. When at a stop auto start has a hard jerk I reported this problem to Cadillac dealership when I first got the car. They claim they couldn't find an issue. The touch pad goes out frequently.
My rear differential completely stopped on the freeway, not moving and saying over 100 mph and my car was barely rolling I am extremely lucky that I did not get rear ended because I was very close to that happening, a few cars had swerved to not crash. Luckily I was able to push my car to the exit and get off of the freeway to wait for the flatbed to pick me up. It is available to be inspected it's just parked until I can get it fixed, the part is $1800 and I have not been able to afford it. I had a mechanic come and look at it and I was told what part it is. There was absolutely no warning lights for this issue.
At 38,000 miles, rear differential leak discovered. Dealership repaired leak. At 42,000 dear differential leak discovered. Prognosis: rear differential failure. Dealership replaced rear differential, shocks. Cost repairs paid by me (cadillac rejected paying repairs).
