2007 Chevrolet Impala Owner Comments

problem #5

Oct 052016

Impala 3.2L V6

  • Automatic transmission
  • 130,000 miles


I have had my Chevy Impala for over 5 years now and recently I have been having issues with the "engine is reducing power" which means my car will not do over 40MPGs. It started doing this very infrequently and now it does it almost every time I drive my car. I have replaced the throttle body and it still continues to happen. Does anyone have any suggestions on how to fix this problem? It looks as if it is a major issue and Chevy doesn't want to fix it. This issue could cause accidents especially if people are on the interstate when it happens. I do have grandchildren who ride in the car so I have to take the other roads instead of the interstate which takes me much longer. So I really wish the CHEVY or GMC would do something about this issue before someone gets hurt or worse dies from it.

Impala LT 3.5L V6

  • Automatic transmission
  • 119,303 miles

Brought the car in March and found out after taking it to a independent garage for assessment the red light check engine light was there along. The code for the check engine light are 442 and 455. But currently the code for the engine is P2122 and P2138 code - reduce engine power. Accelerator Pedal with Sensor may fix issue.

My car's engine light come on and the DIC reads ENGINE POWER IS REDUCED. After this happens the gas pedal becomes hard to push and the over all way my car runs is different. It takes a minute for the car to getr going after a complete stop and it struggles to go over 50
