Interstate driving using cruise control. Cruise control disabled when braking for an exit but left in the on position on the dimmer switch. Cruise control automatically resumes and the cruise light comes on without using the accel or resume button on the steering wheel. Applied the brake immediately and the cruise control disabled itself. I no longer leave the cruise control switch in the on position unless using. Will make appointment with dealer service to correct safety hazard.
Speedometer stopped working just before 2 years / we thought it was a vehicle in front of us with high rf output interfering / we were so wrong / / / earlier the gas gauge was sticking and required multiple twists of key to on without starting car then off on off on off on off . . . . . . . To reset it / later it got stuck pointing to the temperature and wont move at all / / / later the temperature gauge stopped working and will point anywhere / although 1 trip in 20 it seems as if its random setting could be correct / / / now the tachometer is intermittent / seems right when it works which is about 4 out of 5 trips / / / and the security light comes on at random / a few times was unable to start the car without waiting ten minutes / / / sometimes the traction light comes on erroneously / / / cruise control seems to have stopped working completely / / / no idea what will fail next / the internet is full of people with these complaints / / / consumers reports used car ratings has this car as bad in every category of parts that can need servicing / / / dealers want thousands to replace multiple parts but wont guarantee that they will fix the problem / / / internet notes that people have found bad solder joints in the bcm, bad wiring harness contacts, bad sensors, etc. And other design defects / / / I have found three independent companies making alternate parts to really fix these problems. And many solutions to help alleviate the problem. / / / is there an unadvertised recall or fix program by gm to fix the instruments and the bogus security system that only locks users out ?? / / / / / /.
Consumer complained about acceleration problems. The vehicle accelerated even though the foot was off the accelerator pedal. This happened 5 times in the past years. The accelerator only did this when the car was running for over 30 minutes. Previously, the engine could run for over 2 hours before this would happen. The car was in the shop 3 times, and the dealer had not been able to find the cause of the problem. Dealer performed a diagnostic test. But this did not lead to any information. They cruise control module was replaced after testing was done. The dealer suggested that consumer bring the car I when this problem occurred. Consumer contacted gm. They would document the claim and the vehicle 's history and that was all they could do. Consumer took the vehicle to 2 dealerships, and neither could find the cause of the problem.
