“I purchased this vehicle is certified preowned Cadillac and during the warranty time I had a transmission issue that was causing the transmission to jerk when shifting from 1st to 2nd gear and at highway speeds, it would start jerking nonstop. I took it to the dealer and as per a service bulletin, they flushed the transmission fluid and replaced the transmission fluid. This was only a temporary fix because 30,000 miles later the same issues started occurring again and have gotten worse to the point that you can smell the transmission clutches burning and the transmission overheating, possibly causing the number four piston rings to come apart, resulting in an engine replacement as well. I’ve had to replace engine as possible result, but the transmission problem is still there and it has also caused the check engine light to come on intermediately. This could result in a complete transmission failure, causing a vehicle to lose propulsion leading to a possible accident and injuries. This issue needs to be investigated and repairs or replacement made at the manufacturers expense.. This is a four-cylinder turbo engine and an eight speed automatic transmission. In…”
“The contact owns a 2017 Cadillac CTS. The contact stated that while driving at an undisclosed speed, the steering wheel failed to turn in the intended direction. The service power steering message was displayed. The failure had occurred while the contact was in the middle of traffic. The dealer was made aware of the failure. The contact referenced an unknown recall; however, the VIN was not associated with a recall related to the failure. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 45,000.”
“My dream car…2017 Cadillac CTS 3.6L prem. Lux. I’ve noticed a lot of complaints with very low miles under 30,000 service suspension system, car has new Perelli tires 19” and the driver front tire went flat. What’s going on, I don’t want the dealer to take advantage of me. I can’t understand why this vehicle would be giving me problems so soon purchased from Calstar Mercedes dealer on [XXX] of 2023.”
