I have been taking my Enclave to Kerry's for 2 1/2 years. Besides making sure that I do all the necessary maintenance like oil, transmission, radiator etc. they have been extremely helpful with diagnostics. I have had a troublesome engine warning light come on and although we took steps to replace sensors related to the problem it still persists intermittently. Each time I bring it in they immediately check the codes and last time did a significant amount of diagnostic work and investigation and did not charge me for it because of the previous problems. They really do go above and beyond when it comes to servicing your vehicle.
