Wrench light on dash came on. Down with power and up with rpms. Limped it to work and after turning engine off and restarting no further problems until today, then 2x in one day!!! Worried this could cost me!!! A lot!!!

Freequently when shifting from neutral to reverse, or sometimes from neutral to drive, the car surges. It does it more freequently when the engine is hot from driving around (like running errands and backing in and out of parking spaces) Once, we got the wrench light, but it went off after re-starting the car. Once the car went into "limp home mode" but again, after turning it off, letting it cool, and starting it again, it was back to normal. Another time the check engine light came on, so we took it in to have the codes read. The mechanic cleaned the mass air flow sensor as it looked "extra dirty" A couple days later, the problem came back. Now, about a month after the mass air flow sensor was cleaned, we did a lot of stop and go driving, backing in and out of a couple driveways and parking lots, and the check engine light came back on. By the time we could get it to the mechanic, the check engine light was no longer on and of course the mechanic could not get it to duplicate the problem.

Electrical Problems out the ying-yang. Car still runs well but kind of annoying and embarrassing with guests in the car.

Engine surges especially after it gets hot. Read several reports, that indicate it's a fairly serious problem, light break presser will not stop the car. No accidents yet but concerned about this problem that has persisted for some link of time.

I have the same problem. Took to dealer and need a new Throttle body and software updates. $$$$ About $1,000.00 but...this is the first major repair on this vehicle - why did they stop making the CVT transmission and this line of vehicle
