Right after I put my exhaust system the check engine light came on so i hit the little blue button. When I talked to the rep he wasnt hesitant at all about giving me the codes that made the light go on...i beleive they were P0401 and P0404...emissions codes since I removed the cat.......


well today the g/f tells me the truck was actin kinda funny so i again called OnStar to see what codes the system was throwing out and the lady said that she could not give me the codes because I was not a tech.....and that if i wanted the codes take it to the dealership and have the service manager get me the codes....


What kind of crap is this? I spend 30k+ on a truck and she cant tell me what codes MY truck is throwing out. Is this standard practice for them? And if so why?

Might want to remind her that the subscription renewal is paying her salary and ask to speak with her supervisor next time.

Yeah and remind her who's vehicle it is and who paid for it along with who paid for their service. Geez- they are acting like some government agency. She will probably tell you that can’t release that due to the Patriot Act- LOL
