Having problem with my 05 Equinox

I brought my 05 new with 16 miles on it I first had to get a new water pump and after that my oil light started coming on its the light that lets you now your pressure is not right I took it back to the dealer more than three times each time they said they couldn't find out why the light was on and they would reset the light now its 07 the light is back on and I was told one day when I was getting my oil changed that my oil filter pops ever time I start my car and it was to much or not enough pressure in the line have any one ever heard of this.

I have had a few problems with mine too but mine arent engine. Mine are some bumping noises when going over bumps. They have replaced the steering rack twice and now they are replacing the steering column. It is also on its second radio. They also replaced the stabilizer links in an attempt to try to get rid of the noise. Other than those things I love it and I will seriuosly consider another when my lease is up in March 2009.

im having overheating problems....might be the water pump,u got any info on how can i find out if it truly is the water pump¿??
