Constant random recurrence of error codes p2122 and p2138 (either together or on their own) which results in the car switching to low power mode, with very low acceleration which makes it very dangerous to merge into traffic, pull out of stops, red lights, etc. Technically supposed to require changing the throttle pedal sensor, but changing it does not solve the issue, which is electrical. This is a known issue for gm cars.
While driving, without any warning the car engine stalls. No warning at all!! once it stops, ignition key won't work. The only way to restart the car is to disconnect the battery. This is all done in the emergency shoulders, breakdown lanes, its also happened on the highway exit ramps. Luckily each time there was a place to pull over. We could get killed. It has happened numerous times . Sometimes it stalls 2-3 times a day. I am so disappointed in this car. I am afraid to drive it, and how can I sell it knowing that something bad could happen to the new owner.
The rear driver's side door lock actuator doesn't always lock or unlock using the keyfob. It sometimes clicks like it's trying to lock/unlock, but is always . 5-1 second slower than the other doors. It does not have a key slot to unlock the door via a key. The door can be locked/unlocked using the push/pull rod on the interior - until the actuator fully freezes, then it can't be locked or unlocked at all.
2004 SAAB 9-3 arc. The circuit located in the rear of the car, which controls the rear light clusters including the top mounted brake light often fails. I have replaced it twice in just over a year and it has failed again. It starts with one bulb failing and the warning message shows up on the display. Then in a series all the other bulbs start to fail. They either don't work or are always on even if the car is switched off and locked. The entire circuit board was replaced twice at a price of over $700 inc of labor.
While driving at 5 mph and leaving a shopping mall consumer depressed the brakes, and seconds later the traction control failure light came on. Vehicle stalled, and could not be started. Vehicle had been to the dealer twice, who replaced the t6ecm or main computer.
