Monte Carlo

I purchased a 2003 Chevy Monte Carlo in April 2011 from a used car dealer pmm auto sales whom I trusted and dealt with for years, with less than 115,000 miles and within less then 30 days there was signs of minor problems. When I attempted to have the vehicle checked by the car dealership. I was pushed to the side mainly bc im a female. I did notice a white film when I check the low oil pressure light but I didn't think anything of it bc of my lack of knowledge. Come to find out the intake valve gasket was gone and needed to be replaced. The warranty co. Also swindled me only paying for a small percentage of the repair. Leaving me with a major repair bill on a car purchased less than 30 days ago. The mechanic knew the prob B4 I explained it to him in detail and/or any significant research. He std that it is a common flaw on these car models. Sad to say but I got beat in more than one way.

I have an 2003 Monte Carlo ss 3.8. I have had loss of power. It wont go past 4 grand on the tac. I have replaced the plugs and plug wires, coils, fuel filter, idle sensor, tps sensor, egr, I have had the fuel pump pressure check it is 55 psi. I think it may be the catalytic converter. I noticed they were recalled on the 01 & 02 models why not the 03 models?

Monte Carlo 6-cyl

  • Automatic transmission
  • 62,592 miles
I have a 2003 Chevrolet Monte Carlo. Beginning in August of 2006, my check engine light came on one day so I took the car to the dealer to have it checked. The diagnosis was an exhaust rocker stud had pulled out of the cylinder head. They heli coiled it, and it was fine for a while. Then in Sept. 2006, the same thing happened again, this time the opposite cylinder head. This time they fixed 3 of the studs. Now March 2007, the first cylinder head has the same problem. The dealer was unable to repair the head so it was replaced. While the car was there, the technician removed the cover from the opposite and found one rocker was loose again, so they removed that head and sent to a machine shop. I have an extended warranty on the car but still ended up paying close to $300 on my deductible and rental car. In seven months I have the same problem, there's got to be something wrong. Is the some way I can get the manufacturer to do something? 8jb
