NHTSA Complaint #10408436 — 2004 BUICK LESABRE

MY 2004 BUICK LESABRE STARTED HAVING SPEEDOMETER TROUBLE IN JAN. 2011. IT STARTED SHOWING THE CAR GOING SLOWER THEN IT ACTUALLY IS. IT DOESN'T DO IT RIGHT AWAY BUT AFTER AWHILE ON A LONG DRIVE. IT GETS WORSE THE LONGER YOU DRIVE IT. IT CAN SHOW IT GOING UP TO 30 MPH SLOWER THEN IT IS. ALSO THE GAS GAUGE STARTED FLUCTUATING AND BEING ERRATIC AND NOW ALSO THE ENGINE TEMPERATURE GAUGE ALSO SHOWS RUNNING HOT WHEN IT IS NOT. THE CAR PRESENTLY HAS LESS THEN 25,000 MILES SINCE NEW. HOW SAFE CAN THIS BE WHEN YOU CAN'T TRUST THE SPEEDOMETER. GOING TOO FAST OR TOO SLOW? ALWAYS UNSURE, ALWAYS LOOKING AT THE GAUGES? SECOND GUESSING YOUR DRIVING DECISIONS! THE GAS GAUGE AND TEMPERATURE GAUGE GIVE A DIFFERENT READING EACH TIME YOU DRIVE IT. NOTHING HAS BEEN DONE AS OF YET. I WILL BE STOPPING AT THE RACINE, WI. BUICK DEALER WHERE IT WAS PURCHASED NEW TO SEE IF THEY WILL WARRANTY THE PROBLEM THIS COMING WEEK 6/22/2011. *TR
