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 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.

Several types of GM vehicles (approx 2000-2008) have severe leaking and decay problems like my Chevy Impala shows currently. I noticed early February 2012 when my factory speakers stopped working all together. The radio sound didn't get through, door chimes didn't work, safety and warning chimes didn't make noise, etc. A warning chime didn't signal for me to turn off my lights on a rainy day at a grocery store so that when I came back, I was stranded! this however isn't the big problem. This leak under the cowl seems to be prominent in many other vehicles and allowed gallons to enter in under my rugs, floor mats etc., and travel all over the passenger cabin so that wires were submerged, corroded, mold grew, and airbag sensor hubs became islands. Yes my airbag sensors and wiring are submerged with water! please have GM recall this common problem to fix this! my car smells terrible inside from this (especially in the summer) and more importantly, I am worried that my airbags will malfunction. Thank you.

The temperature gauge, fuel gauge, and speedometer have gone completely haywire! the temperature gauge goes to hot and buzzes but my car is no where near hot. I don't know if my tank is full or empty because the gauge is always on the bottom. I don't know how fast I'm going because my speedometer is stuck on 120. The dealership knows that this is a common problem but they insist on charging $500 or more to fix it...just own up and do the recall!!

The contact owns a 2005 Chevrolet Impala. While driving approximately 60 mph, the speedometer reading would not decrease when decelerating. The speedometer reading fluctuated erratically. The vehicle was not taken to the dealer for diagnostic testing or repairs. The VIN was not available. The approximate failure mileage was 128,000.

Driving at approximately 60 mph on the freeway, the speedometer advanced to the bottom of the gauge, then stuck there. The only way I can reset it is to turn the ignition off and on, and sometimes that does not work.

2005 Chevy Impala. First had an electrical problem with the ABS brake system. Traction control feature would engage whenever the brake was applied. This occurred at 30,000 miles. Dealer warranted this. At about 80,000 miles the display panel indicated erroneous problems, ie. Truck open when not. The lights would flash off and on indicating all kinds of issues when none existed. Also the speedometer began to work erratically. The speedometer would indicate speeds of 30-60 mph higher than actual driving speed. Turning the car off/on would gradually lower and reset the speedometer. This occurs randomly with no real pattern. Seems to be electrical in nature. Also could present a safety issue.

The speedometer has gone haywire. You cannot tell how fast you are going. The RPM gauge is going haywire as well. It jumps all over the place. Took the car to the dealership but wouldn't you know it the warranty expired with no written notice from warranty company. The clusters are the root of all the problems and Chevrolet needs to recall to repair the issues described. Another alarming problem with the 2005 Chevy Impala I own is what is called the passlock protection. It also does not work at times and I had to find out ways to bypass the passlock on youtube. This could turn into a dangerous situation if you need to start you car in an emergency and you cant because the passlock will not let you turn on the car. Sometimes you have to wait ten minutes with the key in a certain position. That is totally not acceptable.

My speedometer gauge doesn't work it will get stuck on 20 mph constantly it never reads the correct speed but my other gauges work fine. My transmission shifts/slips harder than it should from 1st into 2ed and 2nd into 3rd. My headlights flicker when I push on my window controls to roll my windows up or down. The heat only blows on the passenger side of my car including on the defrost for the front windows and the rear window.

Since I brought my 2005 Chevrolet Impala in 2006, I have always have the same problem with my passlock system. One minute my car is driving fine. I park it go where I need to go and then come back to my car to leave and it won't start. I took it to the dealership in 2006 and they said it was an electrical problem and claimed that they fixed it. However since then it has happen to me repeatedly. According to the owner manual it says " leave the key in the ignition at the on position and wait until the security light is no longer flashing. Once it stops, turn the key to the off position and start the car." This never works for me. Sometimes the flashing light continue for the whole day, and my car is just stuck where ever the incident (security light flashing) occurs.

Speedometer gets stuck at different speeds. Can't determine real speed when this happens. Was told the instrument panel would need to be replaced. Speedometer started working again by itself so I did not replace the instrument panel. Now it is happening again. Checked online and there are many many of the same complaint. This should be a recall item.

I purchased this car used with 59,000 miles. Drove it home, parked it for 2 days and the car would not start. Returned to dealer who replaced the battery and indicated the drain while off was with specs. Took car home and worked well for about 3 days. On the fourth day the car would not start again. Searched the web and found this is a very common issue with this car.

2005 Chevy Impala with a sticking speedometer. Stays at 85 when parked, and is very erratic. Have read many, many others with same problem and dealerships unwilling to fix this safety issue without fully charging for repair. Cannot afford car payment and over expense for shop repair that should be covered by dealership/manufacturer defect.

Impala 6-cyl

The instrument panel on my 2005 Chevy Impala just stopped working. The gas, speedometer, RPM gauges are all miss reading. When im parked the RPM is redlined, the speedometer reads 90 mph, and the gas gauge reads straight North above the full line. I'm stuck not knowing exactly how fast im going. The speedometer seems to go back and forth to reading correctly at times reading all the way South but never making it completely around.
