So I was driving home from Pittsburgh last night. Everything was fine, cruising along with the radio blaring & AC on. Suddenly the cruise control cuts off, the service engine soon light comes on, and the car won't accelerate. It'll do maybe 2000 RPM max on a flat/upward incline, although you can coast downhill fine. Took it in to the dealer this morning.

Anyone seen a similar problem? Considering it's 1 PM and I dropped the car off at 8:30, I'm getting the impression the service guys aren't sure what the problem is either.

The car is 4 months old and has only 5500 miles on it, it seems ridiculous for a car this new to have a problem this serious.

 

Sounds like LIMP mode. There's a thread or two about this already. Not a common problem, but a couple of folks have experienced it. No known cure yet.

EDIT - seems to relate to this guy's issue.

Wow, I just really hope on the Railliart all these bugs are gone!

 

I had to get a loaner from the dealer for this evening, they're having to call in the technical experts (from Mitsubishi?). What little they did tell me is that the codes the mechanic was getting were saying multiple problems with the throttle body.

 

My bet its the CVT programing issue. I think its flawed. Its going to kill itself trying to be economical.

BRING ON A POWER MODE SWITCH.

 

As I posted elsewhere - I've got my baby back. According to the dealer, Mitsu said that the throttle body was defective.

 

bringing back a dead post, but what did they do to fix it, did they just replace your throttle body. I had this happen today in my 09, the dealer has it and says they are going to get to it first thing in the morning.

thanks

 

so the dealer still cant figure mine out. Said it has thrown a bunch of codes but didnt tell me specifics yet, and they are trying to blame it on my HID' conversion i put in

 

lol get them to put that on paper, and I will sue them for you on grounds of uncut bullsh!t

lol

 

yeah I called and flipped out. Figured out what it was though. Stupid **** always

 

=o HID, lol ok... sureee. how stupid do they think people are.

well i think the reason its going into limp mode is because ur obvious tamper with adding decals and tinting ur windows. lol

 

is this affecting just the CVTs? if so, im glad i got a manny

 

just another reason manual is better than automatic

 

nope.

There was a piece of aluminum between the throttle boddy and intake manifold. Apparently when I was working on installing the intake, it worked it self around and caused there to be a vacuum leak right there. The MAF ofcourse was reading one thing but the engine was seeing another. Kicked off a bunch of CEL's. Got the piece out and the checked the gasket right there and no more problems. Stupid thing from the factory and all fixed now. Has nothign to do with the CVT at all, except for the fact that with the automatic the computer can have much more control over you in limp mode
