4 Engine Oil Leaking problem of the 2000 Chevrolet Blazer

Failure Date: 06/30/2006

Blazer seeping oil from oil pan, will not fix only if I pay 75% due to 90 day warranty,and told if they would fix it I would only create more problems, it was also told by dealer and chevy that it is normal for year and mileage, I don't think so with 47,000 miles, when I owned a 97 chevy with 97,000 miles , no leaks but salesman knew of it 3 weeks after purchase when 30 day bumper to bumper existed,was at dealership July 6, 2006 for all items but chevy nor dealership documented it or the grease fittings, lube, check fluid levels like was suppose to do, salesman checked fluids for me after they neglected to do their job. . So chevy says can't go by salesman because he no longer works there, seeping oil from oil pan is not normal, I didn't receive a odometer paper on it or my trade in. . I feel they are doing me wrong and chevy is backing them up, I even gave salesman number and told them I have a note pad here of all that was to be done with pages after on note pad written on after that day and they won't listen. They never gave me correct mileage on it when I purchased the vehicle.

The oil cooler lines are leaking on my 2000 Blazer( with only 54,248 miles). The mechanic who changed the oil today stated that he has yet to service a Blazer that didn't have leaking lines eventually. Interesting! he also stated that he didn't understand why there has not been a recall. If this is not the proper place to report this, please let me know. Perhaps you can also direct me to the correct place. Thank you.

11 Engine Oil Leaking problem of the 1996 Chevrolet Blazer

Failure Date: 09/21/2001

On my way home from work on sept. 21, 2001, I had to sit on I-435-e- freeway for an hour because of a car accident. I was moving no more than 5 to 10 miles an hour. When I got to I-71-n and I took I-71 to the linwood exit going 55 to 60 miles an hour and then 45 to 50 miles an hour and then 55 to 60 and then 45 to 50. I exited linwood to the east, over to indiana (linwood is the 32nd hundrend blook). I went south on indiana to 3318 indiana. I parked my car and went in the house. I was in the house about 2 to 3 minutes before my neighbors came to my door and said my car was on fire. They were using their water holes to put out the fire. My better-half (trinidad medellin) came out side and open the hood of the Blazer. By the time the fire department came, the fire was out. Superior Chevrolet had informed trinidad medellin that severe oil leak was present from oil filter adapter housing and both oil cooler lines and this leak constitutes a safety and reliability issue. Trinidad did not see any leaks. If this data was known to the NHTSA under recalls, why weren't the customers informed, per odi 978897?.
