Transmission has been worked on over past year. ABS light came on and stayed on due to catalytic converter failure. Wheel bearing failed and was replaced. Automatic transmission had no engagement due to half shaft failure. Engine stalled at a stop due to transmission assembly failure. Brakes were noisy and were replaced, including the rotors. Engine will not start due to battery and starter failure.

Since purchase have returned car under warranty at least 10 times, always for the same problem having to do with the catalytic converter, emissions system, and brakes. About once a month, check engine light flashes, car lurches and is shakey, often with a funny noise and bad smell. Dealership has "fixed" same problem each time, to no avail. Danger factor has increased as I now live in snowy climate. Car has no power, then lurches forward at high speed, stops in traffic, stalls or won't start at all. Tachometer goes up to 4 or 5 before leaving first gear (car is automatic). Dealer sold this car to me as a demo, but contract says used. Help -- this is a terrible, dangerous car and has been in the shop for at least 90 out of the last 300 days.

The 4-wheel drive failed to work properly in snow, it went out. Also, disc brakes were not working when applied. Took to dealer & informed disc brakes were warped. Catalytic convertor had failed. In addition, mechanic found that the muffler did not work properly due to having a hole in it. All parts has to be replaced. Owner feels its a lemon. Mfg is no help.
