2005 Chevrolet Cavalier Engine problems

I was driving on the highway at about 65 mph when my car unexpectedly increased it's speed to about 80-90 mph. I initially thought the car accidentally some kind of way made cruise control come on. I am not a fan of cruise control so I wouldn't have turned it on. After the acceleration, I quickly attempted to get my car back down to normal driving speed because I was on the highway and did not want to crash with anyone by accident. I quickly stomped my foot on the brake. This did not help at all. Matter of fact,...

I drive a 2005 chevy cavalier and on very hot or cold days, or when I drive longer than usual distances (over 30 miles), the speedometer often malfunctions, either by getting stuck reading over 110 mph, even when stopped, or by reading under zero, even when I'm moving. And lately the temp gauge has started doing this as well, alerting to me overheating on cold days even though the engine is not overheating and the check engine light never comes on. It's frustrating and frightening and unsafe. *Tr

On my 2005 chevrolet cavalier, the engine repeatedly cuts out, stalls, while idling or turning, especially in hot weather. It stalled out 5 times in 2 miles the other day and I had to leave it at the auto repair shop. It has been there a week and they cannot figure out why it is stalling. After going online and reading about many other people having the same problem with this car, 2004 and 2005 at least, I felt I should report it. *Tr

I have a 2005 chevy cavalier ls sport. The gas gauge doesn't work with it, when I bought the car none of the gauges worked, they fixed everything but the gas gauge still doesn't work. I think this is a safety issue because if u run out of gas on the highway or downtown it could cause an accident because of you!! Chevy vehicles are the most crappyest vehicles ever!!! My car only has 53 thousand on it and so far the axel is bad and all of my motor mounts are broke except one and I have this annoying cracking noise...

Tl*the contact owns a 2005 chevrolet cavalier. While driving approximately 35 to 55 mph on normal road conditions; pressure was applied to the accelerator pedal and there was an unintended increase in the acceleration. The engine revved extremely high which caused the abs, engine, and traction control warning light indicators to illuminate on the instrument control panel intermittently. Immediately after applying pressure to the brake pedal, the vehicle began driving normally. An independent mechanic was unable to...

Speedometer stopped working at 32200 miles, went to dealer, said approximate cost is $500.00, Talked with mechanic and he said it is very common problem on all gm mid 2000's cars and trucks. Checked online, found numerous complaints and a couple places that said gm is taking care of the problems on the trucks under 70,000 miles but not the cars. I consider the speedometer to be safety related on a car as well as on a truck and do not understand why gm will not take care of a problem that they have been aware of for a couple years. *Tr
