problem #6

Nov 122013

G6 V6

  • Automatic transmission
  • 65,244 miles

The engine light came on and the car would lose power when I was trying to give it gas, such as going up a hill or speeding up to hiway speed. Once you got past a certain RPM it would resume normal function. The garage could never figure out what it was and I didn't want to keep spending money on a crappy car. Maintenance costs for this car were over $2500 a year.

It is ridiculous trying to get on the freeway in a car that doesn't accelerate worth crap!!! I'm constantly having people get right up behind me when I first get on the freeway, then getting mad and passing me while giving me the finger! As if it's my fault! Stupid car!

Had an alarm on my radio that read "power reduced" or something like that. it's a safety feature so you can't hurt the motor. The throttle body was junk on a 3 year old vehicle. Always ran premium gas.

The catalytic converter is bad. Headed to work (grave shift) the whole car starts to shake won't go over 35 mph. Made it to work on the wings of a prayer. Ohh and lots of tears.

(reported on)

G6

  • Automatic transmission
  • 60,000 miles

Engine started having problems accelerating around 60,000 miles. Engine light on dash. I was told that it was my O2 sensor. Part costs @$120, plus labor. I haven't had it fixed yet d/t cost. In the meantime, I was told to run on supreme fuel to see if any clog works it way out. Improved for a while but now problem is back. Pain in the ass if you need to accelerate on hill - verrry hard to do. Just sluggish on flat roads.
