Hendrick Chevrolet - Hoover

I have had Hendrick service my truck since I moved to town. I had them replace an engine and then a few weeks later I smelt gas in my truck. I took the truck in because the work was done at Hendrick. They took a week to find and replace the problem. In the meantime I had to rent a car since they do not have loaners. They had to replace a gas line which one was replaced with the new engine but the other went back. I got the truck back but when it crank me it shakes and the engine squeals which was not fixed. The service manager was kind and gave me a nice discount for my problem but I keep having to go in every time they touch the truck. I think I will just take it to another dealership or mechanic who can actually fix the problems.
