When driving the whole car shakes and the engine makes a loud sound. It doesn't matter if I am going 10 mph or 75 mph the same shaking happens. The engine smells like burnt rubber. Driving feels like jerking not a smooth ride. I have already had the engine oil leak repaired. My car has been in the shop 3x in 2 months for this same problem. The dealership did a transmission systems update which did not help. When driving downhills the RMPS shoot up and get stuck between 3,000-4,000. The dealership could not find any documentation that downhill assist is a feature on this car. The dealership was not able to replicate these issues. I own a 2023 Cadillac XT5 with 30,859 miles on it.

The contact owns a 2023 Cadillac XT5. The contact stated that the brake pedal would depress to the floorboard without warning. The contact had taken the vehicle to a dealer where a diagnostic was performed. The dealer received various diagnostic codes all related to the brake master cylinder. The contact was given a loaner vehicle and the dealer replaced both the brake master cylinder and the vehicle's battery. Despite the dealers repair, the contact refused to take possession of the vehicle due to the prior brake failure as she felt unsafe driving the vehicle. The manufacturer had yet to be notified of the failure. The vehicle was repaired. The failure mileage was 33,770.

The car has a shudder/vibrate and what feels like jerking at certain speeds. I have a 2023 XT5 Premium Luxury 3.6 However, I have taken multiple times to Big O tires had tires replaced, brakes, Lower control arms, I still had a vibration issue. Took back to Big O due to Tire balance issue but came back tires and balance and alignment were fine. I was told that Big O, hooked the car up to a TPS machine and stated my torque convertor needs replaced. My car only has 51,500 miles. They stated that the shudder is between gears 3 & 4. I understand my car powertrain and drive train are under the 70,000 mile warranty. But I keep hearing this is major issue with the 2023 XT5. Making me think I have a lemon since the issue is already happening on such a new car.
