Recall #15757 was performed by dealer on 2/24/2016. The vehicle at the time of the repair had 255,300 miles on it when I took it to the dealer (brookdale Chevrolet Buick. GMC on 5/30/18 when I took it back to the dealer for oil dripping on the manifold it had 258,200. There is smoke coming from under the hood. We had it in storage after the repair and took it out this spring. The wife said it smoked and then I drove it and I had a lot of smoke coming from under the hood. Since the repair we only put 2,900 miles on the vehicle. Surely if the repair was done correctly we shouldn't be worrying about our safety. The car can't be driven as is. The dealer flatly said they were no longer responsible for any more repairs unless I pay them $1,100 to replace the valve cover and valve cover gasket. The car is registered at the dealer under nl companies because I have a rental. They can't seem to put it under my name. I can appreciate their reluctance to redo the repairs but there is no way oil should be leaking again on the manifold after 2. 900 miles. They wrote down the wrong mileage on their 5/30/18 invoice. There should be 4 documents attached if I did it correctly.
