#1 of 427 chevy impala "REDUCED ENGINE POWER" message
Sep 02, 2010 (7:33 am)
Somebody please help me. I have an 07 chevy impala that keeps giving me a "reduced engine power" message, then cuts your power and you can't drive more than about 40 mph.. I took it to a local mechanic and he said that it was a corroded sensor, that was in the air cleaner. He said that he fixed it and set us on our way. A few days later it did it again. It has no pattern, you can be driving uphill, downhill, or on the flat, and at any speed. It is happening more frequently.
Anybody else had this problem. I can't see that there is a recall and I can't think that I am alone on this. I really don't want to take to a dealer, they can be such a rip-off, not to metion the closest one is 1 1/2 hours away. Thanks

The Catalytic Converter maybe clogged, I have a 2001 3800 Engine that just had the intake Manifold gasket changed 80,000 miles and three days later the car has issue with power due to antifreeze clogging the converter. Changing converter now, Dealer checked it and found the converter after I looked at it for three days to find nothing with the engine.

I have been experiencing this engine power reduce message off and on for the last two months, right when i hit 66,000 miles. My speed drops to forty and my check engine light comes on. I havde an 08 chevy impala LT. I have been to the chevy dearlership twice and they can't find any reasoon for this message. They cleaned some connectors on my car and sent me on my way. I can't find a recall either. I am so frustrated, someone please tell me something.

I am having the same problem with my 2010 Impala, I just got it 1 month ago and it was also a rental. I have not called the dealership yet . But I am really concern, with what I have been reading, I do not want to get the run around. I want the problem to be fixed. So if someone can tell what I need to tell them , so they correct the problem the first time around that would be wonderful. Or if you can point me in the right direction on how to handle this situation . I would appreciate any feedback

I am taking my car in today, Now the engine shut off while I was on the freeway yesterday, it stated ignition something I could not read it completely it due to me being so scared that the engine died, and I had to get off the freeway. The car started back up in about 10 mins but I was so scared that I just drove home . , What is going on with this vechicle I haven't even had it for 2 months and all I have been having is electrical problems. I called the dealership andf all he stated was we have to dignose it the problem. I am very disappointed with Chevy . The Service guys attitude was very rude. Hopefully it will be better once I get down there with my husband . If you can tell me if you have heard of this problem and what I can tell them before i get there to help fix this problem. I am ready to give this car right back to them.
