Cruise control was active-on; windshield wiper was on 'fast pulse'; rain was moderate to heavy; road was hilly; event: When the cruise needed to decide to shift gears going up a hill the wipers stopped long enough for the rain to obscure all vision. The stopping was repeatable by setting up similar settings when the rain/road conditions allowed. This condition even occurred at 35 mph, with cruise on, with wiper fast pulse in light rain, again obscuring forward vision, on a much less hilly terrain. Discussions with GM at the time resulted in the statement that because GM or the dealer could not 'observe' the 'stoppage' that 'it did not occur.' Several attempts were made to get the information to the appropriate internal GM group but none responded. Since the condition occurred both in hilly/mountain terrain and in hilly city terrain it seems that it would be an important issue to resolve -- due to the lack of forward vision at the time of occurrence.

Situation: The G6 was on cruise control at about 50 mph, the road was in Vermont hills/mountains, the weather was raining -- from light to an increasing intensity. The wipers were turned on to the low pulse setting, and as the rain intensity increased the pulse frequency was increased one step at a time. When the pulse was at its fastest, and the G6 was proceeding up an incline and the cruise logic was in the process of deciding to shift gears, the windshield wipers stopped enough to obscure all vision. This condition repeated itself until I changed the pulse setting to constant. Then, again, but this time in West lafayette traveling from the main road North out of town up route 443 between route 43 and 52 on cruise at 35 mph in a rain with the wipers on fast pulse the wipers stopped and vision was obscured. Sooo, the hill/incline does not have to be 'mountainous' or very long in duration. The dealer in vt suggested I should just put it on constant pulse to avoid the issue -- duh. The dealer in Michigan attempted to replicate the condition but city traffic, etc. Prohibited the 'experiment'. the GM customer relations contacts simply kept telling me that the condition 'did not exist' because it could not be replicated -- which was the same as calling me a liar. Duh. Yet the GM cr would not allow me to discuss the issue with anyone involved with the vehicle design or build -- because "it could not be duplicated" yet I duplicated the vt occurrence in Illinois in different terrain. Since the 'hill' in West lafayette is very typical of hills in most of the states in the usa it is likely that anyone driving in the conditions noted would experience the same result. Yet, no one in GM will sit and discuss this at a functional level. When the wiper stops and no one can see out the front windshield, whether traveling at 50 or 35 mph the condition is very critical and a serious accident can occur. I have been trying to discuss this frequently since it occurred.

I have an 07 G6 that is having the same issues with brake lights, cruise, and shifting out of park that the 05-06 G6's are. We've had the brake switch changed twice and it hasn't fixed the problem. Even with the brake switch unplugged the brake lights stay on.

I have a problem that intermittently affects different aspects of the vehicle. The brakes lights will not operate properly. When the issues occurs the vehicle is very difficult to shift out of park. The brake lights will all be on with no pressure on the brake pedal. When the brake pedal is depressed the brake lights will go out. Basically working in reverse. When pressure is applied to the gas pedal the brake lights will come back on. The cruise control will not operate when the issue is occurring. Sometimes the issue can be resolved by stopping the vehicle, turn off the vehicle and restart. The issue will also just begin while the vehicle is in motion and may just as suddenly quit while the vehicle is in motion. There are no warning lights on the dash to indicate the issue is occurring. Only at night, in a dark environment, are you able to know the issue is occurring because of the ability to see the center brake light is light. During the daylight, or city light environment, the non-functioning cruise is the only indication of the problem. Improperly functioning brake lights is a high safety concern for me. When the issue is not occurring all brake lights are working properly as is the cruise control. Internet search indicates this is a common problem with this vehicle.

March 2008 my car started not responding properly with my throttle pedal position. I took it to 2 car dealers under warranty to have it repaired. While in stop and go traffic the car will accelerate on it's own. It has traveled in excess of 35 mph on it's own - I usually shift the car to nuetral to get it to stop. As of July 1 / 2008 the dealer has all but given up repairing this problem. I now have parked the car because it is unsafe to drive and hired a attorny to fight GM to repair or refund my money for this car.
