Service theft system has came on randomly which would not let the car be moved out of park. Which also causes the key to not be removed from ignition. The car also has intermittent starts and can be jumped at the starter relay in the fuse panel. This all happened when the car was stationary. It makes the gas gauge and temperature gauge not work but speed and RPM do work.T he lights on the shitter do not work along with rc not functioning and theft symbol showing on instrument cluster also..

Bought car in 4-2009. First throttle went out within 20 days, replaced by dealer. Dealer went bankrupt within a month. Second throttle replaced 8-2010, third 2-2011, and fourth throttle went out yesterday (4-4-2011.) one GM dealer refused to make repair, calling car a "problem child." (I.e. lemon) another said they did not want to, but would replace throttle, but would not handle the warranty. I have called GM at least five times, talking for hours, and they refuse to think this is their problem. I have repeatedly brought up the dangerous situation a throttle going out creates when the car looses power in the middle of a busy street. They just don't care. GM does have a service bulletin out on throttle problems. I have put @ 5,000 miles on the car since purchase in 2009.
