Gurgling noise detected behind center console of vehicle at approx 60K miles. Dealer did not find anything wrong. Now at 84K miles, dealer telling me that I need to replace heater core, radiator, and associated components due to defective coolant (dex-cool). This coolant was originally used by Chevrolet in 95 and 96 Blazer and is now known to break down and result in "mud-like" substance. Risk of over-heating is primary concern. I have found at least 10 other individuals on the internet with similar problems. This is not an isolated complaint. My main issue - Chevy did not detect the problem early enough even though given opportunity and now I am faced with a potential safety hazard and $1200 repair. Also, their coolant is know to be defective as per my conversation with 2 of their representatives. As a consumer, I do not feel as if I should pay for Chevy's mistakes. I am looking to your organization for help in investigating this problem.

Heater hose failed, causing anti-freeze/coolant to leak into vehicle, and allowing heat to enter vehicle while switch was in off position. Dealer notified and refused to correct problem unless cost goes to consumer. Can NHTSA help inthis matter.
