hello
first of all i would like to thank you for taking the time to read this thread, well i have 2007 Tahoe LS with around 60k miles on it, it works great and i love it!

lately i had a problem happens when i drive for fairly long distances in the city , suddenly i hear clicking in the dashboard ( the click u hear when u press on the brake padel to shift from P to N 'it unlocks the transmission to shift ") and the doors lock and unlock themselves and the DIC shows that i'm shifting quickly between D and P, it comes almost in a random timing it stops when i shift to P , when it spams sometimes the RPM goes a bit high , its like i shifted from D to N then goes back to D quickly , it happens whenever the transmission on D or N , its sort of funny to see the car going crazy , but it drives me crazy.

well if u ask me to go to the dealer,our dealer is a simply a thief , he is the only dealer in my country, for example i some sand entered the brake oil tank cause i didn't close cap on the brake oil tank well so it fell , well i got some problems in braking so i took it to the dealer who asked for 150 dollar to check it , after 2 days they called me saying that i got a problem in the brake system , but they don't know why ! so simply they said they will fix it by replacing the whole brake system for just 3000 dollars ! i asked them i payed 150 bucks for the check i should get the report at least , i ended up fixing it in one of the best garages for 170 bucks by replacing this tank .

i did check this problem in many garages most of them didn't know , one of them after plugging a device on my car he said its a short in the body and i have to keep the car in his garage so he make sure about the problem , i didnt trust him , my car works perfect in highways drives
im confused :S

 

Welcome to the fourm...

I would suspect poor connection to the BMC or Body Control Module that I believe is located in/under the dash...
