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.

I am trying to file a complaint about a known defect with all years of Chevy Impala transmission's faulty first gear or pressure control solinoid issues. For the last year I have experienced issues with my car failing to adequately shift from starting off to the 30 mile per hour could feel my car jerk when it finally shifts. So I did what I thought would help and had a transmission flush and filter change which only solved this issue for not even a week. I went onto GM's website and was reading the forums specifically for Chevy Impala transmission issues and there was numerous complaints about the same issue but no offer from GM to even look into this issue. My car started to noticeably have this issue before even having 100K miles on it and right now I have 131K miles. I have followed the preventative maintenance schedule with my car since I took ownership in 2006. I posted my said issue on facebook and one of my high school classmates commented that he works at a Chevy dealership (has for 13 years) and only knows of the pressure control solinoid issue, so apparently GM just doesn't want to do their customers right by fixing even the known defect or followup with the numerous complaints stated on their forum. I just paid off my car and I feel that I shouldn't have to pay such a large sum of money to fix a defect on their part. I also asked a friend of mine, that owns a Chevy Impala, and they too have started to experience the same issus as I. please assist us consumers in probing into foresaid issues. Thanks!

The only event leading to the failure was a loud sound coming from the rear left side of the vehicle. The failure involved a pull to the left and excessive heat being generated from the back left tire. The component that failed ended up being the wheel bearing. I had a mechanic replace it and also kept the old part. The old bearing was scorched (the mechanic showed me) and warped. The bearing could have locked up had it not been replaced, resulting in an accident.

3.4ltr 6cyl base model has had multiple defective sensations for some time now; among those are steering, transmission shifting from a standing stop, braking and odd noises. This vehicle's 5 Y/O with only 20K mi, owned by elders & used locally, I've been driving them, & now I have this car. The left outter tie rod end had to be replaced with less than 20K mi. The steering still has an unstable feel when turning and make a metal to metal clinking noise from a defective (& as told by my mechanic & NHTSA reports, repeatedly reported) intermediate steering shaft. There should be a total recall because of this defective GM engineering problem. There is also a clinking noise occasionally when accelerating from a standing stop; can not tell if this defect is from the steering or something else like the engine mounts. Have not yet discovered this source. From a standing stop, the transmission will occasionally shift abruptly, either from a neutral disposition into 1st gear or from 1st to 2nd gear; the car lurches forward & the occupants heads are whipped back. This is similar to other reports of defective power train functionality I've read about with this model. Braking, when just starting a trip, has an improper feel and sometimes sounds like it's grinding, as if the brake pads or rotors are cracked/worn; this is a sensation I've had with vehicles having 100,000 miles, not on a car like this with only 20K miles. The center arm rest's pad support is flimsy/cheap plastic & has broken simply upon entering & shifting in the seat. I now see why so many police departments have discontinued the Impala's in favor of the charger's, crown vic's, Taurus's and escapes. The us government should be severely fining GM for marketing this car. >>>this car needs to be recalled for many reasons<<<

1. my fuel gauge quit working as I was driving to work. All the other gauges kept working. The needle was pointing down and would move at the bottom when the vehicle was turned on and off. I spent $400 to replace the instrument cluster which appears to be a problem as listed on the complaints section. 2. I purchased a 2005 chev Impala 01/2006 with15,00 miles on it. I started to notice a bit of a hard shifting on take off, only after driving it in the city after about the 2nd year of driving. The problem never left, in fact it has gotten worse over the years that we have owned the car. The problem with my car is the transmission shifts hard and only seems to do it if you did a a lot of start and stopping and you could turn the car off and let it sit for 10 min. Or so then it won't do it again. Sometimes it would go for several days or weeks before it would happen again or will do it several times in a row. When I had the instrument cluster replaced I had them check for codes and found a P1811.

Impala 6-cyl

  • miles
2005 Chevrolet Impala jumped out of park and rolled backwards. The impact caused the garage door to pop open and crash back down and trapping the consumer inside of the garage. The consumer suggested that GM should take responsibility for the defective vehicle. The vehicle also stalled when shifting to reverse from park, the vehicle hesitated to start therefore the consumer had to hold the key from several seconds while the starter attempted to turn over and the vehicle continued to grind.
