Owner report 10269505 · 2009-05-20 (May 20, 2009)
I HAVE BEEN SEEING THAT WHEN COMING TO A STOP MY VEHICLES IDLE STAYS UP WHEN IT SHOULD BE KICKING DOWN TO A LOWER RPM TO SLOW THE VEHICLE. I HAVE TO SMASH ON THE BRAKE PEDAL AT TIMES B/C IT FEELS LIKE THE TRUCK ISN'T STOPPING AND THE ENGINE RPMS STAY HIGH. I HEAR THIS IS A VERY COMMON PROBLEM AND HEARD THE FACTORY IS DOING NOTHING ABOUT IT. IM YET TO BRING IT IN FOR THIS CONCERN BUT WHY BOTHER IF OTHERS ARE BEING BRUSHED OFF BY THE DEALERS. I GUESS GM WILL ONLY STEP IN WHEN SOMEONE GETS HURTS OR EVEN DIES FROM THIS. *TR

Owner report 11747022 · 2026-06-28 (June 28, 2026)

When an attempt to jump start the vehicl…
