Ok well my wife's new Trax had a major issue the other day and is now sitting on the dealer lot awaiting diagnosis and repair. She has the AWD LS.

The check engine light came on 2 weeks ago and I played with the gas cap and it went away. Then the other day she starts driving and she all of a sudden can't go faster than 5 MPH. I understand it's the car going into "limp home mode." She got the following failure lights, 84(engine power reduced), the traction control light came on, the check engine light, the engine reduced power light and the service car soon light (car with a wrench inside).

I know these cars are new but has anyone else experienced this? What was the diagnosis? I'll post the outcome on my end, when the dealer finally looks at it.

That doesn't sound like a typical problem that is happening to people. Sounds like something pretty specific to your Trax. Only thing I could recommend other than waiting for the dealer to look at it is to look through recall notices to see if that might explain anything.

Librado85, were you able to resolve this issue? Our new '15 Trax is doing the same thing. The first time we took it to the dealership, they ran diagnostics, and couldn't find a problem. The last night, just a week later, it did the same thing. It's frustrating and dangerous.

Maybe you can show your dealership Librado85's post? Point them in that direction.

One thing I found that helps a lot is to ensure you are going to a good dealer, and then to find out about specific people you should go to, that goes a long way.

Trax Limp Mode

I have Trax 63 plate and the limp mode keeps coming on with the traction control sign coming on. This is not the first time. It is beginning to get on my nerves.

I found this I hope maybe you can get somewhere with it, if I were you I would try switching off Traction Control or Stability Control when it happens to see if it makes a difference.

If it fails to try to start a lemon law claim but I'm not sure if you have the Lemon Law or anything like it in the UK
