Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Security light comes on randomly, have to wait ten mins to start vehicle. Security light comes on while driving, my gas fuel gauge stopped working so I track the gas my miles.. first 20 miles struggles to go, first thought it was fuel pressure regulator to the fuel pump to tranny to alternator now it wont shift into gear and I don't know what to do one recall for the ignition is ridiculous

I turned the key to start the car and was driving and my gas hand, speedometer and oil indicators just fell to the bottom of the circle. Instead of showing me the amount of gas I have the red needle falls behind the "E". the same is true for the speedometer, the needle just falls to the bottom, and the cold/hot indicator is at the bottom of the panel. Isn't this an electrical problem?

Hello, I just purchased this vehicle from a used car dealer and drove it to work two days later. I work an hour away and take the turnpike....I noticed while I was driving that the speedometer was near 90, and when I pulled into my jobs parking lot I was near 40 mph...the parking lot's speed limit is 10 miles per hour with speedbumps so I knew something was wrong. When I got off of work my gas tank read past the full mark....I have been filling the tank every other day to prevent being stranded. I immediately called the dealer and he took a look at it. I purchased the car on 01/17/15 and today's date is 02/01/15 and I am still waiting to get the problem resolved. I've researched online and seen a lot Chevy Impala have this problem. Most notably 2001-2005 I would be eternally grateful if the matter can be resolved. Thanks, [xxx] P.S. there weren't specific options for the problems. They are:the gas gauge, speedometer, the whole panel....I found out this is called a cluster" or cluster panel" information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

2004 Chevrolet Impala dealer has not received part for recall the consumer stated in December 2013, he began to experience a problem while driving on the interstate at 65 mph. The vehicle would lose power, including the speedometer dropping to zero. A local repair shop inspected the vehicle, and informed the consumer, the speedometer in the cluster had apparently gone bad. The cluster was replaced. However, the problem happened again. The consumer went to another shop and they stated the speed control sensor was not functioning properly. The part was replaced and the problem did not return.

Speedometer stopped working just before 2 years / we thought it was a vehicle in front of us with high rf output interfering / we were so wrong / / / earlier the gas gauge was sticking and required multiple twists of key to on without starting car then off on off on off on off....... to reset it / later it got stuck pointing to the temperature and wont move at all / / / later the temperature gauge stopped working and will point anywhere / although 1 trip in 20 it seems as if its random setting could be correct / / / now the tachometer is intermittent / seems right when it works which is about 4 out of 5 trips / / / and the security light comes on at random / a few times was unable to start the car without waiting ten minutes / / / sometimes the traction light comes on erroneously / / / cruise control seems to have stopped working completely / / / no idea what will fail next / the internet is full of people with these complaints / / / consumers reports used car ratings has this car as bad in every category of parts that can need servicing / / / dealers want thousands to replace multiple parts but wont guarantee that they will fix the problem / / / internet notes that people have found bad solder joints in the BCM, bad wiring harness contacts, bad sensors, etc. And other design defects / / / I have found three independent companies making alternate parts to really fix these problems. And many solutions to help alleviate the problem. / / / is there an unadvertised recall or fix program by GM to fix the instruments and the bogus security system that only locks users out ?? / / / / /

My wife got into a wreck because Chevy has not recalled these issues. My 2004 Impala ABS brakes malfunctioned along with my traction control, she tried to stop at a stop sign and the brake pedal kicked up and would not let her stop she removed her foot from the brake and tried pressing the pedal back down and it kicked up kicking in the ABS and traction control not allowing her to stop and she ran into a snow bank but my insurance paid for the body work but not the mechanical problems I replaced both hubs on the front, quit doing it for a week or so and then when I drive it the traction control and ABS kicks in while im driving down the road. Now my speedometer, tachometer and temp gauge are not workin at 0 RPM my car is doing 90 mph as it sits in my garage not starting because my key will not turn to start it my steering wheel will not lock and because I cant turn my key I can not put my car in neutral to push it out of my garage so I can get it towed I have read so many issues on these and other GM models I am surprised that there was no recalls when I called had this car for 4 years and nothing but problems and money so as my car sits in my garage as it will till these items get recalled I am not putting anymore money in this car I will drive my 98 infiniti that I have had for almost 10 years because I know its dependable. Never again GM will you get another cent from me I have never had this many problems with any car.

Speedometer stopped working. Sometimes it read 90 mph when the car was stopped. Sometimes it read the same thing (like 10 mph) all the time. I had no idea what speed I was actually going, presenting a safety hazard. Problem was gone the next day, but continues to be random and intermittent.

Impala 6-cyl

  • 70,000 miles
While driving a consistent speed, speedometer will fluctuate from stuck at zero to 120mph. Happens constantly. Fuel gauge fluctuates also and doesn't always work. If using cruise control while speed appears correct, the Impala will automatically increase its own speed while the speedometer does not change leaving an unsafe opportunity open for very tragic accidents to happen. I cannot believe that my 2010 Pontiac vibe has had 3 recalls and this Impala has not had any for the instrument panel. Do people really have to die or be injured before something is done to protect us?

2004 Chevy Impala. I go out to start the car and it will not start. I wait 15-20 minutes and it starts. The transmission also shifts hard. The speedometer says I am going 10 when I am going faster than that or it may say 100 when it is parked. Please, recall this.
