Recreational Vehicle Lpg Tank Valve/gauge problems of the 2004 Chevrolet Impala

Approximately a year ago my temperature gauge and gas gauge quit working. I was not too concerned because I knew how many miles I could go on a full tank of gas so I just judged my gas by my mileage counter. Now this evening my speedometer quit working. While completely stopped, with the engine turned off it said that I was going 30 mph. When I was driving, the needle seemed to "jerk" a lot. Also recently my car seems to be sluggish or act like it is going to stall. I have also had some occasions when my car won't start after just turning the key off. If I wait a little while or overnight then it will start like nothing was wrong. I am very concerned because my 17 year old also drives this vehicle and I have to do a lot of highway driving.

I have a 2004 Chevrolet Impala, the speedometer and temperature gauge on the instrument panel does not work properly. The speedometer shows all different speeds even if the car is not moving. The temperature gauge does not work at all. I am also beginning to doubt that the fuel gauge is correct. I was told by my Chevrolet dealer that the cost of repair will be around $700. 00. I learned today on a news report the general motors acknowledges the problem on their SUV's and pick-up trucks, but not on the Impala's. I am still trying to save the $700. 00 for the repair.

The event actually started the day that my wife and I bought the vehicle. We bought our vehicle used from sanger Ford in sanger, CA. First the temperature gauge went out. Later the speedometer stopped working and now our fuel gauge doesn't work. The mechanic at sanger Ford stated that it was the cluster and it was not covered under warranty and told us it would cost $507. 45 to replace. We have since spoken to gm, who instructed us to get a diagnostic and they would take it from there. We paid $85 for a diagnostic at tom benson Chevrolet in san antonio, TX. Gm then told us that there is no recall for the cluster on the Impala, but there are recalls on the chevy tahoe, suburban and the silverado and that if we wanted it replaced we could deduct the cost of the diagnostic from what tom benson wanted to charge to replace it, which was $500. I have seen comments online from other '04 Impala owners complaining about their cluster going out, they just either paid to have it replaced and the ones who didn't have the money to replace it, like myself, are stuck with not knowing how fast they are driving, how much gas they have or if their engine is running hot. Please help us. I know that this is a major problem and gm doesn't want to have to pay to fix it.

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 ?? / / / / / /.
