Speedometer reads erratically either highor low. Will register various speed when stopped. Sometimes will work properly, then go bad again. 1st noticed when read 35 mph on road keeping up with traffic in 60mph zone. Dealer say he has seen a run on this problem with 5-6 in last couple of weeks. At first it would seem okay when it warmed up for 15-20 minutes now really erratic. Requires module replacement at $680 and 7 days to get part. Unsafe to drive with no reliable speed measure.

I own a 2003 Chevrolet 1500 Z71 ext cab pickup. On Dec 23, 2004 the speedometer would not decrease its reading, even if the vehicle was at a complete stop. The speedometer will only display the incorrect speed or top out and not move from 120mph. When I contacted the dealership were the vehicle was purchased they notified me that this is an ongoing problem and the part they need to fix the speedometer is on back order for a minimum of 30 days.

Under warranty, rear driver's spring sags 3/4 inch and more. Just out of warranty, (40,000) speedometer fails to read accurately, intermittent problem. Rear vew mirror display shows backward "F" for seventies, can not isolate temp from compus. Windshield wipers will not shut off when it rains or car is washed.

I have a 2003 Chevrolet Silverado.5 ton. I have had a problem with the fuel level sensor and a check engine light for the last 8 months. My speedometer started to act very jittery for about 2 months and now it does not work at all. It is stuck pointing straight down. Two dealers said they are seeing this a lot, and have a very long back order for parts.

On 4/1/2003, took delivery of a Chevrolet 3500 P/up VIN:[xxx] it has a sudden acceleration. Dealer has had vehicle 3 weeks GM has no cure, they want to drive it and try and capture the data to fix it. My insurance co doesn't want them to drive it because of liability. Where do I go from here. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).
