Had issues with my 2007 impala 3.9l stalling and reducing power on my wife, and at times almost leaving her in or on the road. I have replaced the throttle body, throttle peddle ( twice ) and had the car flashed at the local gm dealer. Now the car not only reads reduced engine power it read starting disabled service throttle and died while she was driving down a busy highway during rush hour.. Causing her to almost be involved in a bad wreck. This seriously needs to have attention of whoever at gm is over safety, cause this issue will end up in a really bad situation if or when someone ends up seriously hurt or killed. I mean you really need to program them to slowly reduce power, not just tell you then shut off completely and have the driver fight and panic to get off the road through traffic, while not getting run over in the process. But if there is a fix we need to know.

I recently purchased a 2007 chevy impala, 3 weeks after purchase while on the highway, the car suddenly slowed down to a crawl, a reduced engine light came on the dash, being as we were on the highway to suddenly only being able to go 20mph was very frightening!! I was able to get the car to the side and had to have it towed home. After searching this issue online I found thousands of complaints from people with the same issue with this same car. I find it strange there was not a recall for this due to it being a serious safety issue. After calling a chevy dealer, they told me all they could do is hook it up for diagnostic tests but it would cost 175.00 just to do that. This vehicle is still parked and we are unable to drive it and still have no idea what's wrong with it. I'm very concerned about driving it again for fear of this happening again and us maybe not being as lucky next time!!!! Serious issue with thousands of complaints online. Simply type in 'reduced engine power' make model and year of car and many people have had this same issue!!!!

"takata recall" while on the highway traction alert came on the message states the engine is slowing down and took it to o'reily's and states the sensor codes alerts that will cause my car to fail by shutting down and locking up if its not corrected and to see if there is any recalls on this malfunction

Engine power was reduced while I was traveling with the flow of traffic. I attempted to accelerate but car started slowing down. Took the vehicle for repair and replaced the pedal position sensor was replaced. I contacted chevy dealership service dept and was told it's a common occurrence. Impalas have a throttle sensor instead of cable. If the sensor goes out, the engine power is reduced to protect the engine integrity. In some cases, it's reduced significantly. The manufacture noted my concern but the rep would not escalate the matter. I went online to file a complaint and there is a chevy forum with similar concerns. General motor reps reply with common responses to take the vehicle to an authorized mechanic and their concern has been noted. I was informed by representative at 800# for manufacture to call back if it happens again. Thankfully I wasn't going at a higher speed in dallas traffic. Not sure if I would have had the luxury of pulling over.

My wife's 2007 chevy impala left her stranded on the side of a busy highway in a snowstorm. She was driving at highway speeds when all of a sudden, her overheat warning light began flashing, and what she described as "a huge cloud of fog or smoke" was trailing behind her. She immediately put on her hazards and pulled off to the side of the road. Once stopped, the digital readout showed "engine overheat, idle engine" and then the engine shut off. The vehicle is at a dealer awaiting diagnosis.

Reduced engine power/ traction control warning/ gas line fuel leak. This car flashed a reduced engine power message while I was going 65 MPH straight away on busy city (in houston) freeway and the traction control warning light came on. My car then immediately reduced speed and would not go beyond 40 MPH. I was told that the gas line fuel leak has nothing to do with it but it seems very coincidental that this all happened in the same day. Gm is putting out a lot of trashy vehicles right now and this should definitely be a recall; especially when there are numerous valid complaints of the same issue. I'll never by gm/chevy again. I am going back to an imported brand

I was sent a recall for my vehicle. I think it is terrible that you have not found a way to fix this problem since it has been known about since 2003 and you kept on manufacturing this product. Public safety is of no concern to you until someone gets hurt or killed and you are forced to respond and even then you do not fix the problem. All people who own this vehicle should be reimbursed as now there is no way now to sell the vehicle privately or as a trade because of this defect. (there was no accident or incident except for the fact that I bought this defective car, and you knew about the defect and let no one know).
