    Reduced engine power

    So I have had my new ATS for a week and a half, 250 miles on it. I have already had it in for service when the check engine light turned on. They said it was a faulty gas cap and replaced it, took a day and a half. On Christmas I was taking the family on a small trip when I had a very scary experience. Making a left on to a busy road I accelerated when all of the sudden the car felt like it downshifted. It was a very violent movement throwing everyone forward in their safety belts. This almost caused a very serious accident. The car was driving very slow and I managed to pull over. The check engine light, stability control and another light above that had illuminated. I also noticed the message Reduced Engine Power scrolling across the screen. I managed to get the car home at a slow pace. All of the warning lights had turned off except the check engine light. Road side assistance towed the car to the dealer and I am waiting to hear from them. This is crazy for a brand new car to have this many issues. I am now getting a bad feeling about my purchase. Anyone ever have a problems with a new car like this and how did the car company handle it? Thanks.

    Sounds like a stability/traction control issue. You did the right thing having it towed to the nearest dealer. Have they given you a suitable loaner while they fix it?

    They gave me one the first time. I did not ask this time. I will wait to see how long they say repairs will be. If it's quick I don't need one, if it will be a while I will get one. The only thing I don't like is they use Enterprise for their loaners. Just one more level of crap to deal with, IMO.

    After following the forums there seems to be way too many problems with this car even considering it is new.

    I'm kind of curious when/if I experience my first major issue. Knock on wood, I've only had some minor software problems and one time my rear back up sensors detected an obstacle and wouldn't let me drive anywhere (I turned the sensors off/back back on and was able to drive)

    It's called mass production. Things happen. We had to take ours in yesterday for an issue. If that issue had been on say a 2nd or 3rd generation ATS then I'd have an issue but it was something that Cadillac just found out and it was fixed.

    I don't share the same conclusion though. It is human nature that we only hear about the problems and gripes. Others want to share their information out there to see if anyone else has the same problem and what was the fix. There are many others not experiencing problems and you don't hear posts saying "Wow no problems with my car and I love everything about it". I frequent other sites like BMW and Porsche and I hear many problems and gripes about their cars too and most are not new models like the ATS and are very established designs and manufacturing. So please don’t jump on the negative band wagon and cause unnecessary alarming comments. Thanks.

    It is the nature of forums to come off negative. Problems are a greater motivation than expectations met.

    It definitely is the nature of forums. On the BMW sites a few years ago, by reading the posts you'd have thought most 335s had fuel pump issues, but in reality only about 3% that did.

    What's your source for that 3% figure? I also thought it was higher, maybe because my fuel pump failed, but I thought given the recall and class action settlement the number was higher. Nonetheless I agree with the point that you mostly hear about problems on these boards, and the number of complaints on the BMW boards are very high but don't seem to scare too many people off.

    By the way, I took delivery last week and love my ATS so far, although I have barely driven it. No problems yet, and much happier with CUE that the Idrive on my Z4

    Quick update. They have a senior tech driving the car with something monitoring the engine. Hopefully I will hear something soon.
