While driving the car it would pop up a message saying -€œENGINE POWER REDUCED-€. Today while driving it home it popped up with a message saying -€œSTARTING DISABLED, SERVICE THROTTLE-€ and then the car wouldn-€™t drive and I had to pull over on the side of the road. For months now when I drive and accelerate at times the car would almost grind. I believe it has to do with the traction control or the transmission.

My car has started slowing down abruptly and displaying Engine Power has been Reduced at random times, but has become more frequent. I have had an independent service center tell me it was the throttle body, so they replaced it. That didn't fix it, so they replaced the accelerator pedal/sensor. It still is happening and when on the interstate, it is so dangerous to slow down with no warning because you can get rear ended quite easily. This first started August 2021 when my wife and I started on a vacation and had to turn around and go home and is still happening, only more frequent. This past Saturday 7/16, I was traveling on Interstate 77 and the engine power kept cutting down about every 10 minutes, so I had to pull over and cut the engine off for a while until it reset. I can't trust it to go anywhere.

To whom it may concern: I have a 2009 Chevy Impala with 100,000 miles on it. The 1st time this issue happened, I was driving slowly, on a side street, in July 2019. Out of the blue, the following warnings appeared: Engine power is reduced, service stabilitrak, service traction control. Immediately my car started running horribly (it didn't want to go, was chugging, and almost felt like the transmission was slipping). I parked it. Later I started it and all warnings were gone, but the engine light was on.. the next day I started it and just the engine light was on. 3rd day I started it, engine light still on. Drove it to a shop, .right before I pulled in, the light turned off! they scanned it anyway & said that nothing came up. The car has driven just fine, no warnings or lights until 11/25/2020. I was driving about 20mph, turned right on a side street and all of a sudden all of the exact messages as before came on. Vehicle immediately started running slow and "chugging"again. I parked it. When I started it again later, all the same messages were still there. It's definitely scary when this happens & since the 1st time it happened, I was nervous to drive it far because I wasn't sure when it may happen again. I went on a Chevrolet forum & read there was a recall for this issue. I was very pleased about that. I put in my VIN & it stated that there are no recalls. So I called GM this morning. The rep said they're aware of this issue, but there is not a recall for it. She then said that it would've covered by special warranty but unfortunately that was unavailable as of April 2019! her advice was to take it to a certified dealership and have it checked and fixed soon for my safety! I asked why there isn't a recall, if it's a known issue and she said I could talk to a customer experience manager at the dealership and maybe they could do something for me. Please help!

This is not the first time this has happened. On the hwy going 60mph, all of a sudden my engine power is reduced and airbag light came on. The next day the air bag light and engine light are both on. Went to my mechanic for an inspection (which I failed due to the airbag) and he informed me to contact the dealership for recall. I did, only to find out the recall is closed and I can't get this fixed unless I come up with a lot of money. I explained I never got anything from the manufacturer about the recall. How can I get my car fixed on a closed recall?

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.

Lately, I have been having issues with the acceleration of my vehicle. Every so often, my engine light comes on and I get a "engine reduced" notification, and my vehicle slows down. Whenever I reach 40mph, my hp meter drops and my car starts shaking. There has even been a time when my car would completely shut off and display "ignition disabled". each time this has happened, the vehicle was moving on a highway. I went to a shop to get the error codes and I will upload them.

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.

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.

What has to happen before something is done about this problem ? traction control light and reduce engine power light comes on going down the interstate and the car shuts down and you have to try and get car pulled over to the side of the road without hitting someone or getting hit. This is a very common problem with this vehicle and nothing is being done about it. I would really like a response on this problem. This happens a lot so your date you want incident happening is really not right.

Car hesitates on acceleration from a stop. Rpms go up but car goes very slow, like if it has lost a lot of power. Once it stops hesitating it bangs into gear and speeds forward. It can possibly cause a crash if driver is not aware its hesitating.

After starting my car and pressing on the accelerator car starts to jerk lights flicker and the message service traction control. The car will sometimes lose power. And does this while driving and will not accererate. I have changed the accerator petal positioning sensor as well as the battery. I do not feel safe driving this care whatsoever. And I've seen that many other Impala have had this issues. This has happened many times. I should not have to pay for repairs when this is clearly a manufacturer issue.

While accelerating the traction control kicks in and cannot accelerate. This has happened while backing up, driving straight, and turning. It has mainly been happening while driving in the city. When I push the gas pedal the car doesn't move. I have almost been hit by other vehicles while stuck.
