Need a mechanic for a 2018 GC
 

Hi all...new to the forum and hoping for recommendations for a Jeep mechanic in the Toronto or Hamilton areas. My GC is exhibiting an intermittent shaking at 70+ that cannot be explained by the dealership's technicians. Wheels are properly balanced and everything has been inspected by two different mechanics, but the problem remains. I need someone who is willing to patiently troubleshoot and not just rely on the vehicle throwing a code (which it hasn't!). Thanks in advance!
