NHTSA — Vehicle Speed Control: Accelerator Pedal Problems

CarComplaints.com Notes: The 2005 Ion still had power steering issues and a defective ignition switch leftover from previous model years, but hey – at least Saturn improved some of its safety rating to marginal, right? Baby steps.

If you had to buy a Saturn Ion – and I would question why anyone would even consider it – I suppose the 2005 could be considered the best of a bad bunch? I mean, GM did finally get rid of that awful VTi transmission, and both the power steering problems and ignition switch defect that plagued owners were recalled. The problem is they waited 10 years to recall the ignition and let over 30,000 warranty claims get filed before they bothered to fix the power steering. So you kind of have to wonder, is GM making these fixes to keep owners safe or just to keep government lawyers from taking all their money? You be the judge.

The contact owns a 2005 Saturn Ion. The contact stated that when the accelerator pedal was depressed the vehicle failed to respond. The contact had to wait before the vehicle resumed normal operation. The failure recurred on numerous occasions. The dealer diagnosed that the electronics on the pedal failed. However, the part to do the repair was unavailable. The manufacturer was not notified of the failure. The approximate failure mileage was 58,000.

Saturn Ion, base model ongoing wiring/electrical issues since December 2006 to presently. The reduced power light comes on and I lose acceleration in traffic situations. First occurrence in December 2006, the pedal actually accelerated in rush hour traffic. I averted an accident. Started at 21K, under warranty until 60K. Now at 47K, and problem still not corrected. It is in the shop right now for the sixth time for electrical/wiring issues regarding reduced power. I picked the vehicle up from the dealer on June 20, 2008. The dealer rewired the ECM sensor and drove 554 miles to test the vehicle. However, on July 1, 2008, the failure recurred. The check engine light comes on and the vehicle loses power. I have on several occasions averted traffic hazards when the reduce power comes on. I have had two different dealerships for Saturn try to repair it, to no avail. It is in the shop now again. They won't guarantee that they will fix the wiring issues to complete satisfaction. I do not feel safe driving this vehicle when the reduce power and the accelerator pedal continues to be defective. They have replaced sensor, modules, wiring connectors, computer updates, accelerator pedals. It will happen again, and I will be concerned for mine and others safety.

Was driving vehicle from my house to my work and I noticed suddenly that whenever I took my foot off the gas even slightly or applied more pressure to the gas pedal tht the vehicle would lose power and jerk back a little bit. I work for GM and get alot of calls from cust's about concerns, but I never thought I'd actually say that I for the 1st time in my life did not feel safe in my vehicle, especially knowing that my vehicle would die or break down at any moment leaving me stranded. Nothing has been done to fix this concern, but one things are taken care of and hopefully corrected I will update things.
