Using automatic light sensor control when lights failed-- 65mph on a dark secondary road- all the lights in the vehicle went out - inside and outside - fortunately it was a straight section of road -- slammed on the brakes and the pickup stopped before it went into the ditch - sure scared my passengers -- had a Mercedes mechanic with us and he said he had read a news letter from the Mercedes people about GM vehicles having complete electrical failures - he said that the article stated the engine had quit in several cases. The lights did functioned on the manual setting. However, after about 20 minutes we arrived home and the lights still would not function in the "auto sensor" position. I started using the "manual " position at night after the incident-- but, several times I forgot to use the manual setting and the same problem occurred. However, switching immediately to manual restored the lights. It is a bit unnerving having the lights quit -- as we live in western Oklahoma and the roads are not as well marked nor lighted like back East. Reported problem to GM customer assistance center -- file number C02315205 -- reported to dealer also -- but - no one else had run into the problem -- they said they checked with their GM contact -- and they had no record of anyone else reporting this problem -- it really sounds like an electrical "contact" problem -- when it get hot or shorts out -- it opens the contact points and the lights go out-- then when it cools -- the auto sensor starts working again. After the first incident--I tried the auto sensor position next morning - the auto sensor worked just like it was supposed to operate. Thus, I could not duplicate the malfunction for the dealer's mechanics.
