Had regular service on vehicle as recommended by owners manuel. Also, numerous other repairs, as needed, ( by service department). Outrageous charges for parts and labor of $3032.00. This vehicle is a 2012 with 38,500 miles. I would classify it as bordering on a lemon!

Always polite and friendly . The service department appointments are on time. They don?t pressure you into repairs that don?t really need to be done like other dealers.
