Three problems related to brake sensor have been reported for the 2003 Chevrolet Silverado. The most recently reported issues are listed below.
2003 Chevrolet Silverado - abs activation during low speed breaking that led to increased stopping distances, intermittent at first but over 3 to 4 months increased to the point that it nearly resulted in an accident. Brought the vehicle to an authorized Chevrolet dealer for repair, diagnosed that the abs sensors were corroded and after testing, found that the "lifting sensor causing different wave lengths at speeds below 5mph". The repair consisted of cleaning the rust build up under and around the sensors and replacement of both sensors. The repair cost $430. 00. Told by the service advisor that this was a common problem in this model and year and advised to file a claim with gm for reimbursement of cost as this repair was not as a result of accident or negligence on the part of the owner. This repair is similar to the remedy mandated for the exact same condition under recall notice 05v379000 for Chevrolet Silverados, model years 1999-2002. The claim for reimbursement filed with gm/Chevrolet was summarily rejected with the stated reason that the vehicle is out of warranty period. Even when apprised that there is a recall in place for the same condition on vehicles one model year older, Chevrolet refused to negotiate this claim. I then filed a claim with the bbb as recommended in my vehicle's owners manual and though helpful could not assist stating that vehicle is out of manufacturer's warranty period. Looking for help in recouping repair cost for damage that was as a result of flawed design from a corporation that refuses to listen to consumers complaints and instead throws up a firewall to deny claims in the hopes of disheartening the claimant until they give up.
The rear brakes are prematurely wearing out and have been replaced three times with less than 40,000 miles. My abs sensors had to be replaced also. Chevrolet is obviously aware of the design flaws of these type of vehicles, based on the number of online complaints I have read regarding the disc brake system of 2002-2004 pickup trucks. Chevrolet went back to drum brakes on the rear for 06 due to the problems, but they will not recall or warranty any of the problems.
: the contact states there is a NHTSA recall campaign 05v379000 regarding the abs. The vehicle has the same problems as indicated in the recall. The abs activated at low speeds, however it was not included in the recall due to the VIN. The dealer replaced a wheel sensor on 9-2-03, but this did not correct the problem. The rotors have been replaced twice, which also did not correct the problem. The contact finally disabled the abs in 12-04 as a solution to the problem.
