Model Years Affected: 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011

Drive Trains Affected: Automatic Transmission, Manual Transmission

Average Mileage: 97,179 mi (32,000 mi - 260,000 mi)

Verified

The speedometer may stop functioning with code P0722 stored in the powertrain control module (PCM). This may be caused by a worn speedometer gear due to coolant contamination of the transmission fluid. If contamination is found the radiator is most likely at fault. The transmission should also be thoroughly inspected and repaired or replaced as required.

    Car bogged down like it mas similar to a misfiring, then I noticed the speedometer was at 0. After downshifting at a coming stopsign, it bogged again & the speedometer picked up again, only to fizzle out again as I accelerated.
    having the mechanic repair the speedometer as we speak... mechanic is concerned there's more to it...

    When driving the highway my speedometer went out and my digital odometer was still visible but it was no longer changing. The check engine light had also come out so we went to auto zone to get a general diagnosis. We were told it was the outshaft speed sensor so we bught the part and had it installed however that did not fix the problem. We took it for further inspection and were told that some coolant may have leaked into the transmission, damaging it. So at least we know whats wrong with it however it will be costly repair.

    Speedometer stopped working and check engine light came on. Repair shop said the gear that runs the speed sensor is broken due to contamination. Have to replace the transmission and radiator. Said it would cost $2500.

    I had trans fluid leaking into my radiator, which in turn contaminated my radiator and all hoses, got them all replaced out of pocket only having the power train warranty, haven't even had the car 3 years.
    After getting the radiator and lines replaced, then had to replace thermostat.
    One week later my speedometer stops working, gear is morphed and not sending correct signal to output speed sensor.
    Dealer claims problem was caused by radiator leaking coolant into transmission fluid.
    None of which is covered by warranty.
    This car sucks.

    I have an automatic, but yes, radiator went bad, and I have to replace my transmission due to coolant mixing with the trans fluid. good thing I bought the top of the line warranty, or it would have been all my expense.
