2006 Saturn Ion. Consumer writes in regards to vehicle sudden acceleration recall notice and requests reimbursement for repairs. The consumer stated when she got in the left turn lane to make a turn, all of a sudden the vehicle took off without applying the gas. Her foot was on the brake and the engine began to race at a high speed. The incident occurred a second time, while at a 4-way stop sign, the engine began racing, with her foot on the brake. The vehicle cut off and the dashboard went black. The third time, it happened, she was pulling into a parking space, and the engine began to race at a high speed, she was unable to stop the vehicle, and eventually she crashed into a wall.
Our 4 cylinder 2004 Saturn Ion has had unintended sudden acceleration problems for several years. I am a patent holding software and hardware engineer and I can state absolutely after observing the behavior over at least 4 years that this is a software issue and/or a sensor issue and not a sticking mechanical control. It is not necessary to even touch or move the accelerator pedal in order for this to occur. Under certain conditions of temperature and humidity, either some sensor malfunctions or some connector becomes intermittent or the software misreads something. At startup the engine runs at an unusually high idle (~800 rpm), and as soon as you put it in gear, the car lunges forward or backward hard and you have to put it in neutral to avoid having it run away with you - all this without touching the accelerator pedal. When you put the car in neutral the engine runs at between 3,000 and 4,000 rpm on the tachometer for a few seconds and then slowly drops back to an idle (~800rpm). As soon as you put it in gear again, the car lunges once again - throw it in neutral - 3,000 - 4,000 rpm, slowly recovers. After two - three minutes the engine stabilizes and the problem is gone. Please note this is all without touching the accelerator - ever! this happens when the vehicle is cold and usually during high humidity or rainy conditions. It is so unpredictable that I have never sought help from a dealer. It is not repeatable in a way that the dealer would be able to diagnose since it happens fairly rarely (sometimes a couple of times a week - sometimes once a month) and inconsistently. If I was an inexperienced driver and if this was a more powerful car, I would no doubt have had a serious accident by now. I have learned to pay attention to the motor when I first start the vehicle. If it sounds like it is idling a bit fast then I know it will try to run away with me when I put it in gear so I just wait for it to idle down to normal before putting it in gear.
On two prior occasions, the vehicle's motor 'revved' or raced just before coming to a stop. A couple of hours later, when pulling into a parking space and applying the brake, the car rapidly accelerated, jumped a curb and ended up finally coming to a stop inside a party store. There were at least 10 feet of skid marks present and a witness from behind that saw the brake lights on. There was a lot of damage to the car and store, all repaired, however the problem that caused the accident has not been duplicated and has not been rectified.
Vehicle is experiencing a problem with sudden acceleration. Owner was driving and had foot on brake at a four way stop. The vehicle began to accelerate up to 3,000 rpm and surged through the intersection. Provide further details.
Vehicle experienced sudden acceleration while in traffic, causing consumer's vehicle to crash into another vehicle. Driver sustained injuries. Taken for repair to the dealer for the second time, but the cause was undetermined even after the computer had been reset. Consumer stated the only way to stop the vehicle was when it hit the other car in front. Put foot on brake to stop the car and it surge forward.
Multiple episodes with this car of sudden acceleration especially when putting car into drive or reverse. Roadside assistance has had to start car for me 2 times. Another time the car stalled while idling 4 times within 30 minute drive. Tonight the car lost power completely while I was driving. I see multiple complaints on this page for the same problem. Saturn has not been able to find any problems on their computer. I would like to fight this with the lemon law but I am so afraid to drive this car now that I want to just get rid of it as soon as possible.
