Fuel/Propulsion System · at 153,000 miles · reported Mar 3, 2016
There is a known problem with the gas tanks on these vehicles. The vapors cause the check engine light to illuminate. In nys this car will not pass the yearly inspection. Chevrolet has an extended coverage bulletin out but it only is for vehicles that have les than 150,000 miles on it or are not older than 15 years old. Whichever come first. Prior to this, their extended coverage was for 150,000 miles or 12 years. I was excluded from the first time due to age of the vehicle when I purchased it and AM now excluded from the second extended coverage due to the mileage. It is absolutely ridiculous…
