When driving my vehicle that speedometer on the RPM does not work, and now I was told that the computer was messed up. I have replaced the battery, and then the fuse under the seat gets really hot, and something needs to be done about it. I have even got a ticket for speeding and my speed O meter was set at 65 and I was told by the highway patrol that I was going 75.

Speedometer does not give true speed sometimes and sometimes it will be right, sometimes speedometer will be at 50 mph when the vehicle is not moving. Turning. Switch off and on. Speedometer needle will go back to zero. Techometer dose not work sometimes. Have cheked on line complaints about this problem there are alot of complaints with the same problem. There should be a recall on all these vehicles.

I had gone to a friends house with my boyfriend and our 10month old daughter the car was working great on 12-31-11 at around 5pm we parked the vehicle. On our way home at about 10:45pm we got on the road car drove fine we jumped on the fwy it was foggy and really hard to see we were on the 54 fwy in san diego approaching the 805 South there is a high on ramp we were going about 55 to 60 and all of a sudden I pushed on gas and lost all power to vehicle it sounded like I was in neutral and because it was up hill and curved very difficult to see us with just hazard lights on. I was praying thinking someone was going to take us out. Every car would swerving around us and honking we finally pulled over to the side of the fwy off of the ramp and turned off car turned it back on and it gave us enough power to get to the street exit. Once there again did the same and at that point we parked and left car on the side of the road after calling a friend to pick us up since we didn't want our baby out on the street that late and on new years. I have also had several other problems ac only works on 5 back passenger panel makes clicking noise when on and back ac works when it wants to. Also RPM gauge doesn't function, car alarm is very faint when place on. I have 3 other children and 1 car and now don't know what to do since we depend on the car. We have had small problems with this car and about 5 to 6 months ago my car engine started knocking and had to be replaced however ac already wasn't working and neither was the RPM gauge. When we replaced the engine the car ran great had a lot of power and everything. This was the worst experience of my life and I thought we were going to die.
