“1992 Geo Storm manual transmission. When engine gets hot ( summer months ) engine idle increases to 2,500 - 3,500 RPM. Must use foot to pull up on accelarator. Car begins to overheat lurches forward. Car also stalls without warning. Heard it has to do with faulty ECM. Very dangerous situation.”
NHTSA complaint #10131943, filed 2005-08, 86,000 miles“I sent one complaint today, with some errors. I am sending this complaint to correct these errors, and also to complain a little more. I can bareley make it to school in my car without worring if it is going to die or not. Several times it has died in the middle of busy intersections not only putting myself in danger, but also the other motrists around me. I am a young kid on a tight budget and would like to see something done about this. Thank you.”
NHTSA complaint #753159, filed 2001-10“Car has erratic idle at times and rpms will stick sometimes well above normal idle. It is ecu that is causing the problem. Quite a few of my friends experience this problem with the Geo storms. A recall is in order if you ask me!”
NHTSA complaint #745100, filed 2001-05“The problem I have been experiencing with my 1991 Geo Storm gsi, is everytime I'm at a red-light or stop sign with the car at a complete stop, my idle will shoot up from the normal 800-900 rpms, to 2,000-3,000 rpms. This is very dangerous on a automatic transmission equipped Storm, since you have to firmly press on the brake pedal very hard to prevent the car from lurking forward and hitting a car in front of you, or injuring or even killing a walking pedestrian that happens to be crossing the street. …”
NHTSA complaint #708032, filed 1999-06“The first ecu went when I was sitting in my driveway the rpms were erratic I got it fixed, ordered a new ecu cost me $950. It lasted no more than 3 months and the same problem developed on the new one. I do not want to keep spending almost $1000 every three months. I also don't want to sell the car and have the new owner have the same problems. I have contacted isuzu, and GM. Isuzu said they do not make cars can't help you GM said almost the same thing thats common but yet they have switched to a new method of making ecu's/ECM's.. Please look into this.”
