I got my Equinox in May of this year and everything was great! Then came August and there were all these problems popping up. First it would hesitate when I accelerated from a total stop so I brought it in and there was a recall to reprogram the computer. I did it, the problem seemed resolved and the car was driving totally different. Now I have this terrible grinding sound when I start the car. At first it only happened when the car was completely cooled down so the dealer had to keep it overnight to hear the sound. They believe its the cam phasers (as per the latest recall) so they ordered the parts and I will be bringing it in on Monday so we'll see how that goes. NOW...the noise is happening all the time, its hesitating upon acceleration again, takes a while to pop into gear when I put it in reverse, and for the last 2 days its making a clunking sound by the rear wheels when I go over this speed bump near work. I've also noticed that when I accelerate from anything over 40 or 50 mph, its very slow like its having a hard time...as if I was going up a hill. It just doesnt pick up as quickly as I think it should and Im not sure if this is normal. I can't even tell because the car was driving one way before the reprogram, differently after, and I think it changed again so I dont know how it's supposed to feel! Any input? ideas? solutions?
