My engine RPM would randomly lock to 4000 rpms while driving, i could rev the car or apply the brakes but it will sit their until it decides to respond. This has happened a few times and mostly down hill and flats. Difficult to replicate. Cooling system has been a plague at around 80k miles i've had to replace a clamp at the back near the water outlet flange which i was quoted $2000 for just the labor alone as the engine would need to be removed.And the water pump failed at around 82000 miles. Also plagued with P06DE "Engine Oil Pressure Control Circuit Stuck On" error code a few times now.

54,189 miles on car currently. Since June of 2019 my car/engine will completely shut off at a red light, or a coming to a stop sign (basically completely stopped or coming to a stop). Its even shut off while in reverse. When this happens, the gear is still in drive. So I then have to put the car in park, press the brake and start it again. It sputters to start again, but it starts. Its getting more frequent, with it stopping up to 3 times at one stop light, and then having to restart it again. There are no codes on the dash. Ive brought my car into crest Cadillac multiple times to try and diagnose this issue. They cannot find the root cause, and it still happening most recently today! there is a new battery, alternator testing in good condition. They have tested the battery cables/lines. This is incredibly frustrating. My car has stopped on me when trying to accelerate and turn into a lane and I was almost hit bc my engine completely shut off. I also called GM and was told without a diagnosis they cant help. Ive spent so much money on diagnostic tests with no answers. I need help please

The contact owns a 2014 Cadillac Ats. While driving 25 mph, the temperature gauge increased and the vehicle began to overheat. All the warning indicators illuminated on the instrument panel. The contact was unaware if smoke was present from under the hood. The vehicle was taken to braman miami (2060 biscayne blvd, miami, fl 33137, (305) 720-2629) to be diagnosed, but the dealer stated that there were no factory warranties on the vehicle. The vehicle was not diagnosed or repaired. The failure recurred. The manufacturer was made aware of the failure and confirmed no recalls or warranties per the VIN. The failure mileage was 70,000. The VIN was invalid.

Afraid to drive my vehicle. I took the vehicle in under warranty because the car lost power on the off ramp from the highway. The air conditioning shut off, and I then noticed nothing on the car was working, brakes, steering, engine!! the dealer could not duplicate the issue. This past Friday it happened again at rush hour and my wife almost got into a serious accident. I am now out of warranty and have a car I am afraid to drive. I have found some other posts of this issue, but no resolution. This should be a recall for safety and if they cannot fix, the car should be replaced.

0N more than five occasions the vehicle has accelerated when coming to a stop. I've had to hit the brakes and shift into neutral to get the RPM's back to normal.the last 2 times my wife has been with me in the car, she now refuses to ride in the car. I've had the car in for repairs three time specifically for that problem. The car will run fine for a short time then all of a sudden the same old problem of accelerating when slowing down or coming to a stop. I do not feel safe in this vehicle and would like the lease terminated a.S.a.P.

The engine stalls while driving, with out any alert. It has stalled on three different dates since I leased the vehicle.

- Boca Raton, FL, USA

I turned a corner, drove through some sand on the road and broke traction. After that, the traction control system lights came on and within several seconds the check engine light came on. I had onstar service run remote diagnostics and they found ABS failing and a cylinder misfire. The car took an immediate loss in power and started to shake at all power levels.

My new Cadillac with only 6700 miles on it had to have a brand new engine put it because of bad pistons. This is a very common thing for Cadillac Ats models. If you go on the Cadillac forums website, you will see many other Cadillac owners having the same problem.

- Cathedral City , CA, USA

There has been 2 occasions my brand new car has stalled and lost power. Both times the car has sat for over an hour. When I get into vehicle it starts up and I take off. Within a minute the vehicle is stalling and fails to accelerate. Each time I have taken it into Cadillac and they can't find a problem because it did not register in the computer system nor does a test drive discover problem. The real concern is if I'm crossing an intersection and the vehicle stalls and I'm in an accident. I don't want to be a statistic waiting for GM to find this problem.

The "check engine" indicator came on, soon thereafter, "stabilitrak" and "engine power is reduced" indicators came on. Ten minutes later, the car shut down in the middle of the highway. After 10-15 minutes, the car started up again with the "check engine" light still on. Car was repaired at a Cadillac dealership. Service representative advised that it was necessary to solder some wires/terminals behind the right rear wheel well fender liner. A service bulletin (pie0291B) identified this problem. This same exact problem arose in mid-February. The remedy at that time was to replace the throttle body. Hopefully, this new remedy will work now that there is a service bulletin to assist with the diagnosis.

While driving the car at about 15 to 20 miles an hour the car came to a complete stop. There was a total shut down of the electrical system. The emergency blinkers could not be engaged, the car could not be shifted. The car was towed into the shop, the dealer advised me the engine failed and a new engine was put into the car by the dealer. We have owned the car for two months.
