Recently reported ENGINE problems on 2008 Chevrolet Impala

The car is not driving smooth. the car is having multiple problems

On interstate driving approx. 60 mph suddenly check engine light came on, and reduce engine speed light on and car dropped drastically down to literally no power. barely had time to get on shoulder without causing accident. went to local mechanic and he said that the issue was the throttle peddle.

Reduced engine power light comes on intermintently while driving had the throttle body and accelerator pedal replcaed twice after i bought the car with 75000 miles on it. still the reduced engine power light comes on. just yesterday i was unable to start my car. throttle problems light came on in window

My car just stopped in the middle of the road in heavy traffic of 45 mph. weather was about 90 degrees f.. message on dash was "starting disabled service throttle." i am lucky not to have been seriously hurt or killed. after pushing it to a side street, it started again and showed "reduced engine power" and went about 20 mph. i saw online this is common problem with many chevrolets. why no recall? so dangerous. repair is estimated at $750.

Driving on highway @ 60 mph when engine dies with no warning. dash shows following messages: "engine power reduced" "serivce traction control" "service stabilitrax" power steering and power brakes stop working. when car key is turned off and check engine codes are cleared, the car starts up fine and continues to run smoothly. luckily i was able to safely stop the car (albeit on the middle of a major highway), turn it off, clear the codes, and start it back up to get out of the way. same problem happened in january 2018. after this i took it to a chevy dealer. they said car was covered under "warranty" for this problem and they replaced the throttle body. one month later same problem keeps occurring. car runs fine but these messages appear about once a month. typically the engine stays on and is only limited in power. however, occasionally the car will die completely without warning, even on the highway. had car brought to chevy dealer. they said they can not fix the problem unless it is currently occurring with the car. they recommended i take the car ...

One day i was driving my car home making a right turn and my engine started making noise and was acting as if it was going to cut off. so i parked my car called my mechanic he came over and looked at the car i said it could be a possible rocker arm that has gone in the car or i could have something to do with the check engine light coming on giving me a code for a cam positioning sensor / solenoid. also when i purchase the car not too long after me driving i noticed there was some noise coming from my back tires. i couldn't figure it out for a while until one day i looked at my tires and noticed that on the inside there was a considerable amount of scraping going on wearing away my tread. it would always seem to happen when i got new tires on the car so i thought maybe the tires were too big for the car but i ordered what the manufactor suggested the tire size should be for the car. so i had a tire specialist look at it and an alignment specialist look at it ...

Very bad knocking noise also electrical fire could've caught on fire

Lights came on dash service throttle, reduced engine power. i was driving down the highway on 8/16/2018 going 55 when the car started to chatter and i struggled to pull over to the side of the road, i almost was rear ended because it was so sudden. i shut the car off and let it sit for a bit then it started and i went on. today it did it and it still wont start after hours.

While i was driving, the car gave a notice of reduced engine power, then a few miles later, another notice came on service throttle disabling service. and the car shut off! with no warning, and no way to get to safety. if i wasn't in an area that had a shoulder i could get to quickly or if there was any traffic near me, i would be dead! this is incredibly unsafe and is going to get someone killed, if it hasnt already! that has to be some sort of flaw in the programing. if i would have been on the highway, which is where i normally am at that time of day, i would have had no time to react and get to a safe area before the car shut down on me. it also locked up the steering wheel and braking system so i had next to no power. it was incredibly scary. i am just glad that i was driving the car, instead of my elderly mother. she very well may have had a heart attack from the fear. in no way should a car just shut down mid-drive like that! i cant even begin to explain ...

My vehicle experiences an 'engine power is reduced' message in addition to losing capability of driving faster than 40 mph likely as a result of a common fault by the manufacturer.
