I HAVE A 2005 CHEVY AVALANCHE THAT I AM THE ORIGINAL OWNER AND HAVE RECENTLY HAD A PROBLEM WITH THE SPEEDOMETER NOT WORKING CORRECTLY. SOME DAYS IT WORKS FINE AND OTHER DAYS IT DOESN'T WORK OR THE SPEED IS ALL OVER THE PLACE. I HAVE HEARD THIS HAS BEEN AN ISSUE ON PREVIOUS YEAR MODELS AND GM HAS NOT DONE A RECALL. NO ONE CAN TELL ME EXACTLY WHAT THE PROBLEM IS AND I DON'T WANT TO WASTE MONEY TRYIN…
AFTER STARTING THE TRUCK AND TURNING ON THE AC THE DRIVER SIDE WAS PUSHING HOT AIR WHILE THE PASSENGER SIDE WAS COOL. THIS PROBLEM HAS OCCURRED SEVERAL TIMES OVER THE PAST FEW MONTHS THE ONLY WAY TO CLEAR THE ERROR WAS TO RESTART THE TRUCK. I HAVE NOT BROUGHT THE ISSUE TO THE DEALER AS IT HAPPENS SO IN FREQUENTLY. *TR
I OWN A 2005 CHEVROLET AVALANCHE AND THE SPEEDOMETER STOPPED WORKING. THE TRUCK HAS 51K MILES AND NOT BEEN MODIFIED. THIS IS A DANGER TO MY FAMILY AND THE COST OF REPAIR IS EXPENSIVE. THIS IS A KNOW ISSUE AND SHOULD BE A RECALL. *TR
2005 AVALANCHE SPEEDOMETER STARTED READING SLOWER THAN I WAS TRAVELING ONE MONTH LATER IT DOESN'T WORK. *TR
SPEEDOMETER ACTS ERRATICALLY, WILL OFTEN STAY AT ZERO, SOMETIMES WILL START AT 30 AND PROGRESS @ 30 MPH ABOVE THE RIGHT SPEED. AFTER CONTACTING DEALERSHIP WAS TOLD I WOULD HAVE TO BUY A NEW SPEEDOMETER. THIS IS A WELL DOCUMENTED PROBLEM AND SHOULD BE CONSIDERED A RECALL. *TR
