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 diesal 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 idiling 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?.
