I was accelerating and merging onto a road and just got into the middle lane. Suddenly the car kept accelerating even though I had stopped pressing the pedal. The engine was revving and the car got up to 70 MPH in a 55 zone. The brakes did not seem to help slow the car. In a panic I shifted to neutral and was able to pull onto the shoulder and stop the car. Even when I was in park, the engine was still revving. I turned the vehicle off and rested it about 5 minutes and was able to restart it. It did not seem to have any problems on the way home after that. It was an extremely scary and dangerous situation as there were cars very close to me. I noticed that my floor mat was much higher than usual and was under the accelerator. I don't know if that could have contributed to the problem. I do often use cruise control. I cannot remember if it was on at the time and I cannot remember if I was accelerating using the steering wheel button. I do not believe I was at the time but the cruise control likely was on. All I remember is it going out of control. It seemed best to report the situation. I am very glad nothing serious happened as it very well could have. I may get a ticket for speeding though. I don't think they would ever believe this happened to me.

Tl* the contact owns a 2005 chevrolet impala. The contact stated that the windshield wipers and cruise control failed to activate. The contact discovered that both functions were not able to be activated at the same time. Either the cruise control or the windshield wipers needed to be activated at a single time in order for either function to operate. The vehicle was taken to a dealer where the failure was undetermined. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

This report is about sudden and repeated headlight electrical system failure in a 2005 chevrolet impala sedan, and a request for a nationwide safety recall and repair at gm expense for this issue. After getting in my 2005 impala sedan at approximately 4:55 pm on 16 february 2012, I started up and drove out on the road then I smelled burning plastic and noticed the headlights (low beam) were out. I tried the high beams and they worked as did the left and right turn signals, the windshield wiper controls and the cruise control functioned. As darkness increased I had to hold the switch in the high beam position so I could see to drive so I could get home. From what I could determine the problem seems to be in the wiring to/from the multifunction light control switch or maybe it is the switch itself on the steering column. The fuses and relays and the all seemed to be in working order but the low beam lights still did not work. This failure is extremely dangerous and happens without warning. This is the second time this has happened to me now. With dealer parts cost for a replacement multifunction light switch at $350.00 alone, not to mention labor costs and the criticality of lights while driving means this should be a required safety recall item. I have searched mechanical forums on this subject and there are many such occurrences documented, but gm does not seem to think there is a common problem or a reason to investigate and fix the malfunction. This problem is common knowledge at gm dealerships nationwide. Smelling burning plastic is an indication of a serious electrical problem which could lead to an onboard fire in the car in addition to causing injury and or death from a sudden light outage at night. Again, I request a nationwide safety recall and repair be initiated as it appears to be a manufacturing defect and an extreme safety issue.

2005 chevorlet impala: the speedometer gains/drops speed at any given time without warning causing miscalculation of speed during travel. At first, the speedometer returned to the original state, however, after resetting the cruise control function, the unit failed to register speed properly. It has affected the maintenance and performance of the vehicle. Ultimately, the RPM and speedometer gauges, cease to work properly and the car tends to skip between automatic gear shifts. Also, I received a traffic ticket in the state of nc due to the speedometer malfunction. In order to fix this problem for my vehicle, 2005 chevorlet impala (mileage: 103,117k), the instrument cluster has to be uninstalled from the vehicle, rebuilt, and reinstalled back into the vehicle according to my dealer and a licensed mechanic. This repair on average ranges $400-$800 (www.carcomplaints.com). According to research, speedometer failure is a common but expensive problem among 2000-2006 chevorlet models.

Tl* the contact owns a 2005 chevrolet impala. The contact stated the speedometer was exhibiting failures by inaccurately reading the speed of which the vehicle traveled. In order to maintain an accurate speed, he would have to utilize the cruise control mechanism. The dealer advised the contact that the entire instrument cluster would need to be replaced. The contact was concerned that only the stepper motor would need replacement as opposed to the entire instrument cluster. He was also concerned with being unable to determine the rate of speed in which he was traveling. The failure mileage was 67,000 and the current mileage was unknown.

Tuesday, 1/27/09, while driving on a local country road to work at 6:15 am, vehicle headlights and other exterior lights went dark. Dashboard lights stayed on, but other exterior lights went dark for 8 to 10 seconds. Same thing occurred again monday morning, 02/02/09. No dimming or warning, lights just went off and I was driving in darkness. 02/03/09 took impala to gm dealer to run diagnostic. They determined problem with the multifunctional high/low beam lever switch (this unit also houses the cruise control, windshield wipers, and directional light controls). Est for repairs $735.00. 02/07/09 had the unit replaced at another garage for $435.00. I kept the defective unit. Have since done research to find other people reporting this same problem occurring on other impalas ranging at least from model years 2001 thru 2005. In some cases the headlights stayed on, but they were unable to switch the headlights between high and low beam. I feel this is definitely a safety issue. I contacted gm customer service to relate what happened as I believe this is a very serious problem. I feel that due to the high potential for accidents involving injury or even death, this multifunctional lever switch should be "recalled".

Speedometer said I was doing 87 MPH when car was shut off and in park. Took car to dealer, had instrument cluster replaced. Also had them check pop in the steering( made noise when I bought it from dealer with less than 31,000 miles on it. Dealer replaced instrument panel cluster, steering shaft and cruise control sensor. ( cruise control would just shut off and work periodically.) it was really just an adjustment on the brake sensor switch that needed adjustment. Had to take car back for the adjustment to brake pedal sensor.

Tl*the contact owns a 2005 chevrolet impala. While driving less than 70 MPH, the vehicle would not decelerate when the brake pedal was depressed. The contact continued to pump the brakes until the vehicle eventually slowed down. Periodically, while traveling in residential areas or areas where the speed limit is less than 55 MPH, the vehicle will accelerate on its own. The contact would remove his foot from the accelerator pedal and the vehicle acted as if it were stuck in cruise control. The dealer believed that the cruise control may be the cause of the failure. The failure and current mileages were less than 92,500. Updated 11/12/08 *bf updated 11/13/08.
