I recently purchased a 2003 Silverado 2500HD 4wd Crew Cab with 6L Auto. I was tracking my gas mileage by the odometer for the first few weeks and noted the gas gauge wandered quite a bit. Drops from full to 3/4 in no time then stays between there and 1/4 forever, then down to 1/8 and back up to 1/4 and so on. Once mileage was established I quite checking odometer and without a second opinion I ran out of gas today at 1/4 tank by the gauge. As I sat on the Interstate I checked it several times before it rested on slightly less than 1/8. The low fuel light has never come on. Is this system tied into the computer? Does the dealer have to recalibrate the system (ie computer) or could it be just a loose wire or bad sensor? Any info will be appreciated to prevent further embarassment. Thanks.

Mostly likely your fuel level sender is faulty. I'd have to look at a scematic to be sure, but I believe the low fuel light is tied into the gauge, so if the gauge never goes to empty, it won't come on. The fuel level sensor is part of the fuel pump inside the fuel tank. I'm not positive if you need to drop the tank to access it, but if you take it to a shop, do the mechanic a favor and have the tank close to empty to simplify the process.

Delphi settles GM parts issue

Company pays $100M to mend warranty issues and agrees to replace 1.1M electronic parts.

David Shepardson / Detroit News Washington Bureau

WASHINGTON -- Delphi Corp. will pay General Motors Corp. at least $100 million to settle long-standing disputes over warranty issues and also will replace 1.1 million electronics parts -- worth more than $80 million -- at no charge as part of a wide-ranging agreement between the companies.

The settlement, reached Aug. 14 and made public late Thursday, opens a window into the costs GM has incurred in dozens of recall campaigns as a result of parts supplied by its former parts unit. GM has blamed dozens of warranty claims on shoddy Delphi parts, especially electronics.

The companies won U.S. Bankruptcy Court approval to release only an edited copy of the agreement. The agreement resolves all outstanding issues between the companies and sets the stage for Delphi to emerge from Chapter 11 bankruptcy by the end of the year. Troy-based Delphi has filed a final reorganization plan.

Since GM spun off Delphi in 1999, the automaker has had many disputes with the company over warranty claims.

GM spokeswoman Renee Rashid-Merem said Friday that the agreement "clears the slate" between Delphi and GM "and resolves a certain group of outstanding warranty issues."

She said the agreement covers as many as 50 warranty issues; the settlement refers to at least 43 warranties.

The major issue resolved involves 1.1 million electronic parts that are part of instrument clusters, according to a heavily edited version of the agreement that has been made public. The instrument cluster is the electronic brain behind the instrument panel on the dash.

With the agreement and an improving relationship with Delphi, GM hopes to save $2 billion annually in parts costs.

As Delphi exits several businesses, GM will represent a diminishing share of its revenue -- down to a quarter or less than $5 billion by 2010.

Delphi attorney Jack Butler said the agreement saves Delphi "hundreds of millions of dollars in potential liability."

Defective parts replaced

Under the deal, GM will receive $47.5 million to replace defective electronic parts and Delphi will provide 1.1 million new parts at no charge through 2014.

In addition, GM will have a right to buy additional parts at no more than $83 each.

For instrument clusters equipped with Switec stepper motors, Delphi also will provide bulbs and motors at its cost.

In another issue, Delphi will pay GM $175 per repair for up to 107,000 vehicles -- or as much as $18 million. GM would not divulge what part is involved.

Delphi also may sue a supplier over one of the defective parts. If successful, the company has agreed to give GM part of any proceeds exceeding $8 million.

During the dispute, GM withheld $5.4 million in parts payments from Delphi. Delphi won't seek the payment.

Meanwhile, two GM investigations into other allegedly defective parts by Delphi remain ongoing, "and GM has not yet determined if Delphi has any responsibility," according to the agreement.
