Automatic Transmission Control Module Problems of Saturn ION

The car made a loud noise when I pressed on the gas. It would not accelerate fast enough for the highway and the speedometer was not working. I'm guessing the car could go at max, 20mph. The speedometer remained on 0 while the acceleration had to go up to 3 or 4 just to keep the car moving. The check engine light was on. I took the car to gm dealership/certified Saturn service right then, and they charged me $360 to replace the transmission control module. The service guy told me that when mechanics first did the electrical diagnostic check, the car failed 32 markers, but when they did an electrical diagnostic check after replacing the transmission control module, the results confirmed that all the car's problems have been fixed.

* other affected part was speed control. . . . Aside of the current recall issue having been a problem since I purchased the vehicle in 2005 (which has "been repaired"-I guess so if you call repaired the car trying to start itself, not starting at all, current pcm overload thanks to soo many negative codes being thrown for this worthless piece of junk. ) I have filed numerous complaints with the dealership about the throttle body and am constantly and consistently provided the same answer and it is becoming a big problem. You see this car has left me stranded numerous times (to the point where I cannot keep count any longer) because the throttle body is trash. Not one but two check engines lights appear on the dash, the car shakes (literally to the point where it feels like every plastic panel is going to fall off), I cannot travel any higher than approx. 10mph and have to pull over, turn the car off (keys of course become stuck in the ignition due to the faulty switch) and wait until my car is then ready to start and the throttle body wants to operate as it should. I am now filing this complaint as the most recent codes pulling are once again the throttle body and the now the pcm. This part needs to be added to recent recalls. It is not safe to be traveling at 45mph or higher, then the vehicle shuts down and lowers speed to 10mph or less-esp. If you have no where to pull over safely (yes, this has happened to me on more than once. ) I have my car back from the recall the car to still wont start, tries to turn itself over & keeps my keys stuck in the ignition. My steering column has been busted open on the bottom in order to release the keys which is ridiculous yet my car is still not functional due to other faulty, crap, junk, trash (whatever you would prefer to list them as in this documentation) parts that I will most likely be expected to pay for yet again.

While driving approximately 65-70 mph on an interstate, my vehicle just died - no warning. This was the second time it had happened. There is no power & must be pulled off the road & restarted. This is a very dangerous condition - rapid deceleration on a congested highway could be fatal. When I took it to the dealer, they told me nothing showed up on the computer, therefore nothing was wrong with the car. Talking to the Saturn customer service rep returned the same response. I am very afraid to drive this vehicle, it is a very hazardous condition and the car is only one year old. It is a 2004 Saturn Ion. The dealer refuses to replace anything because "nothing is wrong.

The contact bought a 2005 Saturn Ion on 12-10-04. The first 50 miles he had to take it back to dealer because the cruise control was not working. The dealer fixed the cruise control under warranty. The dealer had to get a new computer program for the car. Since then he had to take vehicle to dealer five times because the car sputtered and died sporadically. The last two times was on 9-26-05 and on 9-30-05, and on 9-26-05 the dealer replaced the automatic transmission body control, tcm, and power train module. Repaired all wiring and connectors. During test drive, the service light was still on. He believed the dealer reset the service engine light. The contact picked up the car on 9-29-05, and on 9-30-05 the check engine light was still on. The dealership replaced the engine wiring harness at that time. The contact picked up the car on 10-03-05. He has only driven the car once sine then and the check engine light has not yet come back on. The contact has talked to a field representative from Saturn several times, and he told him to got to the ok dmv.
