2003 Chevrolet Malibu: adaptive cruise control problems

Filed Sep 11, 2019 · Acceleration · 42,178 miles · MO

I was driving my car in town, I went to slow down my 2003 malibu the car kept speeding up, the throttle would not disengage until I physically lifted up on the underside of the gas pedal. I immediately took it over to have it checked by a certified mechanic and they also experienced the same exact issues only when the car is moving. They put it on their service computer and I was told that no codes came up and the the only way they were able to get the automatic acceleration to stop was to disconnect the cruise control module. The mechanics shop disconnected the cruise control and it has not happened again since that was disconnected however, this was a extremely scary situation because braking doesn't help the car still continues to accelerate & peel out, putting the car in neutral doesn't help either the RPM just shoot up & keeps going forward.

I have a 2003 chevrolet malibu that I purchased new on 12/27/02. The ignition switch had to be replaced on 7/23/2014 at 70,328 miles for $307.13. I would like gm to at least pay this amount. There is a gm 14350 recall on this car. In talking to gm they would only consider paying for this, if the problem was caused by rotation of the ignition key I am a man 71 years old and have owned many cars, most purchased new. I keep most cars 10 years and over 100,000 miles. I have never replaced and ignition switch until now. This problem took about 3 months to diagnose. The initial problem developed when the cruise control turned off while in use. It was very intermittent and not predictable. Then the check engine lite came on. The codes indicate a problem with the oil pressure sending unit and the cruise control. The next time the check engine light came, there were no codes. The next set of problems was the power window, ventilation (AC and fan), and radio would not work. The main indicator of this problem was the fuel and temperature gauges would not work. I would get various warning lights after starting the engine including ABS, battery and others. The problems got worse as the temperature got hotter. Half way between milwaukee and appleton, 100 miles into a 200mile trip, we stopped at a rest stop. Upon returning to the car, I couldn?t get the fan or windows to work or eliminate the battery warning light. Fortunately, the back windows were open and inch when we left the rest stop. About 10 minutes after leaving the rest stop, everything came on. The car became unusable because of these problems. Taking it to and independent shop the owner was very patient as day after day, nothing would fail. Finally on a hot sunny day with the car in the sun, I was able to get the car to fail. Replacing the ignition switch fixed all these problems.

This is the second time I am having this problem...the same problem everyone else is having....car wont start due to anti theft issue....luckily my car was in a parking lot at a grocery store. This really needs to be addressed by gm because everyone I know is aware and if I am injured in an accident because this fails while driving - I will find a very good lawyer and collect all the other complainers online for this same issue and file a class action lawsuit - there are plenty enough to do so....this is getting rediculous. How many people have to die before gm steps up and actually fixes the problem? They recalled for the cruise control accelerator and while I did respond and take my car in they told me mine was not an issue...only to discover a year later it is an issue...I just deal with it like I will this one I guess....unbelievable that no one cares except the family members of the people driving these 23k dollar vehicles....I cant sell the car because everyone out there knows about this problem and I would be selling a lemon....now what?

Stuck accelerator: on 4/22/08, took foot off gas pedal -- car did not decelerate and maintained 47 miles per hour for 0.86 miles. Made sure cruise control was turned off. Rpm's still stuck at 1.5. Proceeded through a green light and car continued at 1.5 RPM's for the next 2 miles. Approaching a 2nd intersection, I decided to pull off to the side of the road to be able to turn off the engine, but there wasn't a shoulder; so applied brakes to turn on to quieter side road. Barely made turn. Had brakes down hard and car still traveled at 20 miles per hour. Hit emergency brake and car slowed to 5 MPH. I then put it in neutral and turned off the engine. Took it to spur chevy for repair. They found the prior owner had work done per recall campaign # 04v528000. Nothing came up on their scan test, no fault codes. Cruise control checked out ok. They diagnosed it as the top of the throttle body needing cleaning. This is the 4th time the throttle has been cleaned in the 1 1/2 years I've owned this vehicle. Prior 3 services performed by the seller (barry dodge) on 8/7/07, 6/5/07 and 4/5/07 were requested as the engine routinely idled at 1500 rpms. The 4/22/08 incident was the first time the brakes weren't able to stop the car. The engine was acting sluggish in the weeks prior to 4/22. The oil change wasn't due for another 1000 miles (barry dodge or valvoline). I don't use synthetic oil. I always add fuel injector cleaner after an oil change. I prefer sunoco gas and use their least expensive grade.

Dt: the consumer states that on 2003 chevrolet malibu the cruise control was still active even when the driver had his foot on the brake. The switch on the steering wheel was turned off and the cruise was still activating and speeding the car up. The consumer put his foot on the brakes several times trying to get the car to stop. The consumer finally was able to get the car to stop, but he had to put the car into neutral. The car had to be turned off completely. It set for about 5 minutes and then vehicle restarted. The car sat for a few minutes and then the car was back to normal. The consumer called the dealership and checked to see if there were any problems with the car, and the dealership had not ever heard of this happening before. The manufacturer has not been contacted at this point. The speed was 65 MPH and that was with the driver's foot on the brake. *ak

I have own three chevy malibu a 1998, 2002 and I just got a 2003. However, I noticed that gm has removed there cruise control light off of the dash board when you turn it on. The other two malibu's I own had a dash light come on to let you know the cruise control is on. But the 2003 does not it only has a little light on the cruise button on the steering column and its hard to see during day light. I think this is a very dangerous as you may not know if your cruise is on which could cause a accident. Could you please look into this for me.
