Model Years Affected: 2006, 2007, 2008, 2010

Drive Trains Affected: Automatic Transmission, Manual Transmission

Average Mileage: 80,680 mi (8,100 mi - 150,000 mi)


The automatic transmission may develop shifting concerns. On lower mileage vehicles, upgrading the software in the powertrain control module (PCM) and the transmission control module (TCM) may correct the problem. As the mileage increases, internal transmission damage can occur. Repairs could involve replacement of the valve body or a complete transmission rebuild. Whenever major transmission repairs are made, it is important to be sure the PCM and the TCM have the latest software updates to help prevent these issues from reoccurring.

    Started shifting hard between 40-50 mph. (3rd to 4th gear. Problem got worse and eventually would not shift out of first gear-no warning light came on until this occurred and now it sounds like I may need a new tranny. If you have this problem it won't hurt to have the throttle position sensor tested. This may have caused the start of the problem.
    Should not happen!

    Shifting rough. Especially when accelerating at around 35 to 40 mph. Even slips out if drive occasionally .

    Put in in gear, a big thunk until about 2 miles, then it works good all day. Just happens in the mourning after car sits all night.

    I have the same problem. My transmission slips, sometimes. And when it does it's quite a jolt, & makes a whining noise

    if I'm going 50 to 60mph and slow down to 30mph or so for a red light or curve and then push the throttle to accelerate it will down shift violently. I think it's down shifting into 2nd gear. it's done it since I bought the car at 90000 miles.

    transmission fluid started leaking, and ALL came out once started. when cold, no leaks, had it filled back up (VERY expensive fluid for this transmission type compared to others) held fluid fine, car warmed up, leaked all fluid out again (did not drive) took to transmission shop...$2,800.00 to REBUILD. This car is a POS, DO NOT BUY!
