The service engine soon, stabilitrak, and traction control lights continuously illuminate my dashboard. It has happened approximately 6 times. Each time the dealer has found basically nothing wrong, just replaced a spark plug each time, changed the oil, and cleared the codes. The car has stalled on multiple occasions. I was almost rear ended by someone because a light turned green and my car was stalled. Prior to it stalling it violently shakes, which is just a little bit more rough than the constant shaking it always does. Also recently it has been having trouble starting. Everything seems to be related and is getting worse. The dealer extended my warranty to almost 90,000 miles but I feel unsafe in this car because of all the problems that it has and all the new problems that keep coming up.

I have experienced an intermittent shudder/jerkiness in the past month while driving the vehicle at low speeds. Today, while slowing and turning into a parking lot, the engine shut off and I coasted the vehicle into a parking space and stopped. I turned on the ignition and the car started immediately. When I got home I searched the internet for issues and found this thread on the Cadillac forums of others with similar problems: www.cadillacforums.com/forums/Cadillac-Ats-technical-discussion-forum/391273-2013-6-speed-manual-stalling-affected.html I called my local dealer and spoke with [xxx] in the service department. He said that they are aware of the shudder at low speeds and have a fix for that problem. He said that they have not heard of the vehicle actually stalling. I told him that he could read about it on the forum above. He asked me to bring my vehicle into the dealership to have some transmission parts replaced. I am concerned that this might only resolve the jerking, but not the stalling, which is a major safety issue.

When the vehicle is coming to a stop or slowing down with the car in either neutral or the clutch pressed all the way down, the vehicle will stall. The stall is not abrupt but very subtle. The car does not jerk forward but just dies without the driver knowing. Cannot tell that the vehicle has stalled until I try to re-engage gear and press the gas. Always happens at under 5 mph, right before the car has come to a stop or is rolling to a stop with the car in neutral or clutch pressed all the way down.

Cruising down a hill probably in neutral, car stalled silently with no bucking or noise, just died. Numerous attempts to start the car were unsuccessful. After easily 15 attempts and approximately 30 minutes the car started but was with family, at night on dark twisty and hilly road and did not feel confident to drive it. Had it towed ultimately for Cadillac service. In shop for more than a week, tech could not find or duplicate problem. Happened again a week or so later, in neutral coming to a red light, complete silent stall, after about 10 minutes and several attempts the car started and I drove back to Cadillac service. Again no problem found after in shop a few days. On my way home it happened again at a red light but started on first. I feel unsafe driving car, especially with family in it which I haven't done recently. First stall particularly was in a dangerous place and police would not let car stay on road and we pushed it off the major road. Unexpectedness and perhaps inability to restart quickly are frightening and a major safety issue.

Since buying this Cadillac Ats 2013, 2.0T rwd manual, vehicle new, the engine has stalled several times. The stalling occurs when the vehicle is idling in neutral (at stoplights, in traffic). The stalling happens in both warm and cold conditions. The stalling is not like normal manual transmission stalling where the vehicle lunges forward. The stalling is silent. You do not notice the vehicle has stalled until you put the car into gear and attempt to drive. The vehicle has been taken to a Cadillac dealership to inspect the issue (lindsay Cadillac of alexandria). The technicians were unable to reproduce the issue and there was no resolution. Approximate service date was 09/26/2013.

The 6-speed manual Ats has an issue with stalling, usually when coasting to a stop, and less frequently on initial acceleration. It is not due to poor release practice with the clutch. The car will die unexpectedly when coasting, which kills the electric power steering, which makes for an unsafe situation. This happens infrequently, and I don't really know what combination of things leads to the stall. I have changed the way I drive the car in order to minimize coasting or using the transmission for deceleration. This helps, but there are still times when I get surprised at an intersection by the car being dead when I'm ready to accelerate. It is a very quiet car, especially at idle, so if I'm watching traffic and not the dash, it can die and I don't know it until I hit the gas again.

My vehicle is a 6-speed manual...twice now in the last month it has stalled at a complete stop even the clutch is fully depressed.

When coasting to come to a stop the vehicle engine will stall/turn off. This has happened numerous times since the first incident in June. This is a 6 speed manual transmission equipped vehicle, and the transmission is either in neutral or the clutch pedal is depressed so that the engine/transmission are decoupled. I have been able to watch the tachometer when it has stalled twice, and then the engine just shuts off, very abruptly (no shaking, or noise). It has also happened when slowing to take a turn with the clutch pedal depressed, which is very difficult to get back started as you are trying to drive and not cause an accident (plus the steering wheel locks). I have reported this to the dealer, and they have tried to diagnose it, however no fix has happened. It will normally stall about once every week or so, it is very intermittent. The dealer went as far as to blame me for stalling the vehicle, they said I didn't disengage the clutch at a high enough RPM which is completely untrue and regardless the car was in neutral and I was coasting to a stop (therefore it would be impossible to stall the vehicle in gear). I am not the only one with this issue, there have been numerous people on forums complaining of the same issue. My car is currently in the lemon process with the BBB autoline program as this has happened multiple times. Dealer/GM can not duplicate the issue and has no idea what the problem is.

While driving my manual transmission cad Ats it stalls without warning or reason. It stalls mostly when in neutral, like when sitting at a red light, or pulling into a parking place. It also stalls when in first or second gear, like when turning a corner. I am not pulling the clutch out too soon and hence stalling the car myself, it does it all by itself! the car gives no warning shake or noise, it simply is off, often without my knowing it is off. This has happened to my brand new Ats since the second day of having it, and has ever since, approximately 7 weeks now. It occurs with the gas tank full, almost empty, and in between. It occurs on flat streets, and maybe at an incline. It occurs when cold in the morning, and after hours of driving. It occurs day and night, with and without passengers. The dealer has had the car in twice to investigate, with no luck. This is ridiculous!!

Vehicle quietly stalls and has happened numerous times since purchasing the vehicle less than a month ago. Brought it to the dealer but they basically just say it is designed to stall in certain instances which I believe is just nonsense and unsafe. I have read online that this is happening to other Ats owners so I know that this is a serious and unsafe issue with the 6spd Ats.

I have the 2013 Ats 2.0 turbo and I had a few issues with it.the first is steering, sometimes feels like power failure, its the only new car I owned when the car is off the wheel turns completely.also pulls to right.other issue I get banging noise when put in reverse, and a few times sounded like trans making race noise.the cue system is a joke, when my trial for xm ran out I tried to listen to fm rdi and that's a joke, I cant listen to one song, there's static eighty percent of times.other issues ride is horrible rides like a trans am and shakes when hit bumps.after coming out of a Acura and Honda I now know why I stayed away from GM.oh forgot the engine shakes at idle feels like stall, then revs up.all the dealer does is says meets designed function.I ask myself a car this expensive is it supposed to be crap.
