Latest 9-3 acceleration complaints
When I used my cruise control sometimes it engages and does not engage. It did this for over a month. When I first bought the car, I did my research on it and it said that it has a steering fluid loss problem, because the quality is poor. I am curious to why there has not been a recall on it yet.
Concern 1 as a female it is a safety issue to be stranded in my vehicle, recently what I thought was a battery issue turned out to be a key fob issue. I have been stranded with a well cared for vehicle that has keys that start and get to destination, but have gotten back in my vehicle and the car does not recognize the fob. Concern 2 I have noticed that the cruise control is automatically coming on, and I have to manually turn it off, there have been times when I was not aware until until I took foot off accelerator and the car still traveled at the cruise speed, tapping the brake did not disengage the cruise setting.
Frequently the car stalls suddenly in traffic, looses power I can't accelerate this is very dangerous potential to get hit. The other problem is the car vibrates and all of sudden a lot of smoke comes out from back and rich gasoline smell comes and the speed turns to 0. I turn it off for five minutes and restart sometimes it starts ok sometimes it vibrates again. This happens very frequently
While driving the ignition switch turns to the off position suddenly. This happens when there are any vibrations in the car such as when I reach into and shut the center counsel, shut the glovebox, when anything even lightly grazes the key fob, when a balloon popped in my car and even when I sneeze in the car! When this happens the car completely looses power such as lights (interior and exterior), power steering, speed and basically all controls of the car are lost. The car ignition has moved to off at many...

speeds including 65 mph on the freeway, 50 mph, 35 mph, 25 mph and even while backing out of the driveway. This is extremely dangerous! I can't drive on the freeway because I am deathly scared my car will shut down when I hit a bump in the road. If that was to happen I would be dead in a second! This faulty ignition could cause great harm to not only myself yet to innocent people on the road. This is the second ignition switch I have put in my saab and it has 94.5K miles on it. Saab's are famous for their electrical ignition issues and I beg the government to please step in and demand a recall.

I was driving car on middle lane on highway approaching traffic, when my car completely shut off. This was after getting a complete tune up including oil change, new batteries and tires. Towed car to repair shop and after repair, the engine light remained on and then there was smell of gas and car continued to stall. Took car back to repair shop, where the fuel injector was replaced and gas smell was eliminated. But engine light remained on and car completely shut off again. Took it to repair shop, yet again. This...

Tl* the contact owns a 2008 saab 9-3. While driving at various speeds, the vehicle failed to accelerate without warning. The failure recurred numerous times. The vehicle was taken to a dealer, where it was diagnosed that the intake valve needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The approximate failure mileage was 80,000.
Tl*the contact owns a 2008 saab 9-3. The contact stated that while driving at 60-70 mph, the cruise control activated independently. The contact mentioned that the brake pedal was applied to deactivate the cruise control. The failure recurred on numerous occasions. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.
This has occurred on multi occasions. Usually in cold weather the car usually while braking will report a complete failure of the brake, anti-lock brakes, and stability control. Speedometer quits working, and message appears to come to a complete stop. Once you stop and turn off the car, and then restart all messages disappear and car returns to normal operation. The system may lead to an accident. This is the five incident over the last two years. *Tr

Multiple shorts indicated on sid. Original message "electronic stability control failure". This is a common complaint amongst saab owners for this make and model. Occasionally, an associated an abs failure indication will appear while traveling. Have not noticed a loss in abs function yet, but it was dry when these shorts occurred. The failure is assumed to be associated with the cruise control function and its use has been lost. *Tr
Tl* the contact owns a 2001 saab 9-3 convertible. The contact stated while attempting to engage the brake pedal, the accelerator pedal extended to the floor with out any warning. The vehicle was taken to the dealer and the technician was unable to diagnose the failure. The manufacturer was not made aware of the failure. The vehicle was not repaired. The failure mileage was 100,000 and the current mileage was 108,000.
At 65 mph, the gear shift knob, shift cover and assembly separated from the car - the base-metal stick shift was all that remained, and thus the safety latch that prevents car from being shifted into reverse, instead of a forward moving gear, normally attached to the exterior, was now missing. Alas, safely shifting into any of its 6 gears, was not an option ... It's odd, but per its original manufacturing specs, the entire transmission system in the 9-3, has zero locking mechanism to keep the knob and cosmetic housing from separating. Numerous other reports have been reported to dealerships and across the internet. Gm still covers 9-3, 2008, under its warranty policies. *Tr

Tl* the contact owns a 2007 saab 9-3 sport combi wagon. The contact was driving 25 mph uphill when the vehicle abnormally accelerated to 40 mph. The vehicle ceased unintended acceleration as soon as it hit 40 mph. The vehicle was taken to an authorized dealer for inspection yet the failure was unable to be duplicated. The vehicle was not repaired. The contact stated the failure had occurred at least twice. The current and failure mileage was approximately 27,000.
