Independence, MO December 2007 Law firms Girard Gibbs, LLP and Shughart, Thomson & Kilroy, PC announced a tentative agreement with General Motors in their suit over performance and service issues surrounding DEX-COOL coolant and related cooling system components. While the case was originally certified in Missouri, the agreement covers the entire United States. (Cases were pending certification in several states.)

Final agreement is expected to be reached by all parties by January; concluding details to be announced at the time. Here's the agreement as of today:

We are pleased to announce that we have reached a tentative nationwide settlement with General Motors...

You will have the option to be included in the settlement if you incurred out-of-pocket expenses for any of the following repairs:

1. A replacement of the lower intake gasket, made within 7 years or 150,000 miles of the date of initial delivery for 1995-2003.5 Model Year vehicles with 3.1-liter V6 and 3.4-liter V6 engines, where OEM lower intake manifold gasket was a nylon/silicone gasket, and the vehicle was equipped with Dex-Cool coolant.

2. A coolant sealability repair (including, but not limited to, throttle body gasket, upper intake manifold gasket, lower intake manifold gasket, etc.), made within 7 years or 150,000 miles of the date of initial delivery for 1995-2004 Model Year 3.8-liter V6 engines (RPO L36), where the vehicle was equipped with Dex-Cool coolant.

3. A Dex-Cool sludge repair, made within 7 years or 150,000 miles for 1995-2000 Model Year S/T light trucks and sport utility vehicles with 4.3-liter V6 engines and equipped with Dex-Cool coolant.

The settlement will require you to provide proof that you owned or leased the vehicle at the time of the repair and that you paid for an included repair. If you do not have a receipt, ask the auto repair shop that did the work to provide you with one.

The terms of the proposed settlement are confidential while we work to finalize the settlement papers for court approval. If the court preliminarily approves the settlement, the parties will publish, mail, and email a notice that describes the terms of the settlement and your legal rights. We hope to obtain court approval and get notice out by February 2008. At that time, we will be able to answer inquiries regarding the specifics of the settlement and how to file a claim. In the meantime, you should retain all receipts you have for repairs to your vehicle
