My vin should have been included in this: N182186881-01 - Special Coverage Evaporator Core Icing, Leak Revised Warranty section I have had the issue for many years due to not receiving the notice. The car leaks, hisses, smokes and does not cool at all. I was told I must only take it to them for 250 diagnostic but they also said it was a havoc reprogramming that cost the 2,500 to fix. I have a estimate from a triple a recommended mechanic that says its the evaporator coil. My miles just hit 80,000 but its been going on for years because I haven't had the money to fix it and make payments. Chevy arbitrator states the miles are low and the dealer i bought it from, Conly in Brighton Michigan, should put my vin on the recall list. They say they don't know how/will not. The arbitrator didn't give me on digit for her call back extension. I do have proof of the car having no air at 49,000 miles when a mechanic couldn't find the issue because it was to far down in the car. I don't trust taking the car to them after being diagnosed without seeing the car. BBB auto said I exceeded milage but i wouldn't have if I would have been informed asap My vin should have been in the recall. I have the same make and type of car. Why did they exclude me? I hardly drive the car and was an essential employee . everything was closed I was in the year allowed and under the miles if I would have got the notice Please help
