I just bought a 2015 Chevy 2500HD Duramax...I love the truck but wondered why it has had two owners. The last one only had it 2 months. While driving after we bought it with factory 36000 mile warranty already expired, The speed O and tach needle would loose power and start down toward 0... then it starts working again....it goes in and out over and over.... sometimes it causes the Trailer break system to throw a fault (with no trailer), the tire pressure will also fail and then come back online. also the blinker stops blinking in dash only... blinks fine in mirrors.. Then the next ten time I drive it it may be fine then it does it again... it only "fixes " itself if you turn it off and let it set. Seems like a loose connection... but bumps do not seem to effect it. Has anyone else had this problem. We have always had Fords....thought we would give Chevy a try.... hope we didn't go wrong..... Thanks for your help.

 

Don't discount the condition of the battery or the cable connections to the battery. Modern electronics are very voltage sensitive, much more than the engine starting process.

 

Thanks.....you are the second person I have heard this from......I will clean them today..... they look fine but you never know.

 

Hello patraney,

We're very sorry to hear about the speedometer and gauge concerns you're experiencing with your truck, as we can understand how frustrating this can be. Have you had this checked out by a GM dealership yet? As our team is not technically trained, we rely heavily on our dealer technicians to provide all diagnostic information. If you're interested in a diagnosis at your dealership, please let us know and we would be more than happy to assist in setting up an appointment for you.

Sincerely,

Chelsea D.

Thanks for your concern....BUT.... I did not buy a CHEVROLET product to have to spend hundreds if not thousands of dollars to work on it right off the bat.... Is this a free diagnostics.... if so I will schedule it....I have always been a Ford guy..... now I'm thinking of dumping this like the other two guys did and get a dependable truck.........
