NHTSA Complaint #10369176 — 2003 CHEVROLET SUBURBAN 1500

I WAS DRIVING TO A STORE IN MY CITY WHEN IT FELT LIKE I WAS NOT DOING THE SPEED LIMIT AND GOING SLOWER THAN NORMAL. WHEN II GOT TO THE STORE AND TURNED OFF THE CAR, I SAW THAT THE SPEEDOMETER WAS REGISTERING 20 MPH. I STARTED THE CAR BACK UP AND IT DROPPED THE SPEED READING BY 5 MPH. I DID THIS 3 MORE TIMES TILL IT REGISTERED ZERO MPH. WHEN DRIVING HOME, I NOTICED THAT I WAS STILL DRIVING SLOWER THAN NORMAL AND WHEN I GOT HOME AND TURNED OFF THE CAR THE SPEEDOMETER READING WAS SHOWING 25 MPH. I LOOKED ONLINE AND SAW THAT OTHERS ARE HAVING THE SAME PROBLEM. THIS PROBLEM CONTINUES TO OCCUR EVERY TIME II AM DRIVING MY 2003 CHEVROLET SUBURBAN. I HAVE NOT TAKEN IT TO GET FIXED YET AND HAVE CONTACTED CHEVROLET TO SEE IF THEY WILL FIX THE PROBLEM FOR FREE SINCE IT SHOULD NOT BE HAPPENING. THIS COULD POSSIBLY AFFECT THE VEHICLE SPEED CONTROL WHEN SET. *TR
