Recently reported ENGINE problems on 2009 Chevrolet Impala

While driving on roads and interstates, i frequently receive a dash notification "engine power reduced" and my service traction control and check engine light comes on. when this happens, my vehicle loses speed and cannot accelerate above 40mph - dangerous, especially on an interstate. the notification lights and symptoms occasionally go away after turning the engine off and on, only to come back later. i cannot find and answer to this problem.

Tl* the contact owns a 2009 chevrolet impala. the contact stated that several warning indicators illuminated, including the abs, air bag, service traction control, and stability control. the contact also heard banging noises coming rom the rear of the vehicle, resulting in rough driving. the manufacturer was notified and advised the contact to take the vehicle to a dealer. the vehicle was not diagnosed or repaired. the failure mileage was unknown.

The vehicle shut down and i cannot start it because of the ignition switch causing the entire vehicle to become inoperable. i was pulling up in my drivewaywhen the vehicle shut down.

Earlier this year my car started flashing a "reduce engine power" and "service traction control" together. my car sounded like it was working harder too but i was city driving less than 30mph so i didn't otherwise notice problems. this happened rarely. a few months later i was on the freeway just getting on (flat road) and the warnings came on suddenly. then as i got over 40mph, my car engine shut down and my steering wheel locked. luckily i was able to make a slight turn off my wheels enough to get to the side of the road. my car flashes these randomly after random lengths of time of the car being on and driven and it's almost a daily occurrence. i've seen online no one has been able to solve the issue.

The impala displays service traction control followed by engine power reduced. throws a code for throttle body sensor, but that does not fix the issue. accelerator pedal position sensor is another reason they say, which also does not fix the issue. my car has shut off on me going down the interstate, on a highway, and and over a hill. it shuts down and says 'starting disabled, service throttle' with no warning at all. several people have had the same exact problem and no one seems to know how to fix it. they say wiring but it never fixed anything.

Car drives for 15 minutes then display an "engine power reduced" and "service traction control" light. car hesitates to accelerate the eventually cuts off after a "service throttle body light" comes on. car cut off on the highway at 70mph. whenever there is a problem with the car these lights come on. it doesn't specify what the actual problem is.

Tl* the contact owns a 2009 chevrolet impala. while driving 70 mph, the traction control indicator illuminated and the message "losing engine power" appeared. afterwards, the steering wheel seized and the check engine warning indicator illuminated. the contact applied the emergency brake and the vehicle stopped. the contact stated that the vehicle was also included in nhtsa campaign number: 16v507000 (air bags). the vehicle was taken to yemm chevrolet buick gmc chrysler dodge jeep ram (2195 n henderson st, galesburg, il 61401, (309) 271-0106), but no assistance was provided. the vehicle was not diagnosed or repaired. the manufacturer was not made aware of the failures. the failure mileage was 131,000.

I started my car and the check engine light and service traction control lights both came on. i got on the highway and tried to accelerate to merge into the lane and my car would not accelerate and the steering wheel locked. luckily i was able to get into the emergency lane before my car shut off, but i was very close to being blasted by an oncoming semi truck. this could've been fatal to me if i had not gotten over in time.

Bad solenoid in transmission causes car to jerk upon acceleration. transmission slips. usually happens taking off from a stop with a slow acceleration. feels like being rear ended and can cause sluggish acceleration. problem needs to be addressed with a recall as many other impala drivers have experienced this same issue. issue has happened at least 9 times within a 6 week period.

I was driving alone on the highway and noticed that the rmp gauges was going up and down, then suddenly a message on the dash read, service traction control, then a few seconds later another message read, engine power reduced and the car would not pick up any speed. this was very scary and confusing because the next day i had no isses but has now it did the same thing today. please help.

The radiator fan stop working do to electrical problem i change sensors and relays n still won't work i had auto shop test the fan and the fans works. it stop working on its on

The engine will shut off. then the stereo will turn off for a second then come back on and display service stabilitrak. the vehicle was stationary at a stoplight. the engine has always come back on when trying to restart it with the key.

Low oil pressure light, shut off engine keeps coming on. oil is full. so far i have air bag light, traction control light, engine light, engine speed reduced light all on! how are these auto's not being recalled! i will never own a chevy again! unsafe piece's of junk!

While driving on the interstate at 70mph, air bag light, engine light as well as traction control light came on. felt as if brakes were on. dash read "service traction control" & "engine speed reduced". 140,000 miles

Engine suddenly died while i was driving. i pulled over to the side of the road and it almost caused an accident because power steering went out. i was able to start the engine back up no problem. i had a check engine light on because of the oil pressure sensor. i had just replaced it the day before. i suspect it had something to do with that, but im not sure. if i was on the highway im pretty sure i would have gotten in an accident. this isnt the first time this car has almost caused an accident because of faulty car parts, this car is dangerous.
