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.

Currently car has 140,000 miles. 1. Car hesitates and stalls into gear. It accelerates slowly and jerk and jerks and jolts into traffic constantly. Started around at 130,000 miles. 2. Every time I turn on the heat from the air conditioner and vice versa, it makes a loud clicking and clacking sound that lasts for about a minute and it is loud enough to be heard outside the car. Started around 10,000 miles. 3. Was driving down the road when the dash starts chiming and displaying the oil pressure is low and to stop the engine. I stopped and checked the oil and it looked fine. This is ongoing and is frustrating. Started around 125,000 miles. 4. I am beginning to notice that all of the above defects occur once my car reaches a certain mile.

My son was driving on the highway and the light "reduced power to engine" goes on and the car stalls. After half hour it started but drove slowly so he was able to get of the highway and we had it towed where some work was done such as some sensors. It worked fine for a couple of weeks and last night it did the same thing. He is in college so he took it to local shop and they can't recreate it and don't know what is wrong. They will try some more sensors but this is a hit or miss which is costing real money. Now we don't know when he will be stranded or if it will ever be fixed. Not very reassuring.
