NHTSA Complaint #10519383 — 2005 CHEVROLET SUBURBAN

AT APPROXIMATELY 4 YEARS AND 45,000 MILES AFTER PURCHASE OF MY 2005 SUBURBAN, THE TACHOMETER BEGAN FAILING WITH INTERMITTENT LOW READINGS OR NO READING. SINCE THE VEHICLE WAS OUT OF WARRANTY AND THE TACHOMETER ISN'T REALLY VERY USEFUL FOR AN AUTOMATIC TRANSMISSION VEHICLE, I WAS NOT OVERLY CONCERNED AND I DID NOT BRING THE VEHICLE IN FOR REPAIR DUE TO THE ANTICIPATED HIGH EXPENSE. SHORTLY AFTER THE TACHOMETER FAILURE (ABOUT 55,000 MILES) THE GAS GAUGE BEGAN FAILING WITH ERRATIC READINGS. ULTIMATELY THE BEHAVIOR DEGRADED TO A PEGGED COUNTER CLOCKWISE CONDITION WHERE THE READING NOW STAYS AT ALL TIMES. ALTHOUGH INCONVENIENT, THE 'MILES TO EMPTY' INFORMATION DISPLAY SEEMED TO CONTINUE TO WORK NORMALLY AND I DECIDED I COULD USE THAT METHOD INSTEAD OF HAVING A REPAIR PERFORMED. I'VE BEEN USING THAT METHOD EVER SINCE WITHOUT ANY ISSUES, BUT I TEND TO BE CONSERVATIVE AND FILL UP BEFORE I COME CLOSE TO BEING EMPTY. WITHIN THE NEXT SIX MONTHS AFTER THE GAS GAUGE FAILED (ABOUT 60,000 MILES), THE VOLT METER BEGAN GIVING ERRONEOUSLY HIGH READINGS OF ABOUT 20 VOLTS. IT WAS A PRETTY RARE EVENT. WHEN IT SHOWED THIS OVER VOLTAGE CONDITION, I CHECKED THE CHARGING VOLTAGE AT SEVERAL LOCATIONS AND FOUND THE VOLTAGE TO BE NORMAL. WHEN I DETERMINED THAT THERE WASN'T AN ACTUAL OVER-VOLTAGE CONDITION, I WASN'T TOO CONCERNED ABOUT THIS INFREQUENT ISSUE. SEVERAL MONTHS AFTER THE GAS GAUGE FAILURE, THE SPEEDOMETER BEGAN FAILING WITH LOW OR NO READINGS. IT STARTED OUT TO BE A VERY RARE OCCURRENCE. THE ISSUE NOW SEEMS TO BE OCCURRING WITH GREATER FREQUENCY. THE INCREASED FAILURE RATE CONCERNS ME SINCE IT CAN RESULT IN A SAFETY HAZARD AS WELL AS COULD RESULT IN A COSTLY SPEEDING TICKET. I WAS NOT NOTIFIED OF ANY OF THE GM CAMPAIGNS FOR THIS ISSUE ON THE SAME MODEL VEHICLE ON DIFFERENT VINS. GM'S POSITION IS ANY REPAIR WILL BE AT MY FULL EXPENSE (APPROX $600). *TR
