| I have noticed when taking off from a stand still the rpm are high and the engine is very loud and noisy. it seems as i am driving with a v-8 or even a diesel engine. i am sure gm has been notified of this as well as some of the other complaints i have reviewed has stated the same thing. something needs to be done about the idling of the rpms when your just taking off at a normal speed and the reduction of the engine noise as well. my 2002 impala with 136k miles on it sounded better than this and it needed some work done to it. i thought i would at least get the best quality from upgrading to something more up to date but was very disappointed. if your going to pay good money for a vehicle you should have a decent car that doesn't sound like a piece of crap. can gm get it to where it is running as good as it looks? *tr | |||

| Engine makes a knocking noise while accelerating. i drove another one and the noise was even worse, that one had 15000 miles on it. this seems to be a common problem with them all. i am very unhappy with this car. i don't enjoy hearing all this noise from a new car. (now has 6000 miles on it) if i can't resolve this problem it will be the last gm car i ever buy. the dealer had me drive another new 2012 impala when i mentioned the noise, it also sounded the same. gm definitely didn't address this problem before production. | |||

| Engine makes a ticking noise or knocking noise while accelerating , i'm very concerned with this being that this noise started the next day after i had the car home from the dealership . i'm hoping this isn't a safety concern but it sure is a customer dissatisfaction. the dealer has tried to isolate the noise and could not and said i would have to wait for the manufacturer gm to figure out what is wrong. i'm very depressed about this having spent good money on a new car just to have it make more noise that a 40 year old car , and then being told i have to wait till someone complains enough to see if it can be fixed. i been told that this is a new engine in the impala and now am wondering if this engine is going to become a problem for thousands of people like myself. i have read some major concerns from people about the 06 impala and hope this isn't where my car is headed. any help that i could get would be very appreciated, thank you. | |||
