The Chevy store next door wanted to charge me $400 to diagnose a reoccurring check engine light on my brand new 2020 Duramax with less than 4000 miles. after waiting weeks for an appointment i decided to call the GMC store. Ryan the service advisor got me in immediately and got the correct part ordered. the repair was done in the exact time Ryan quoted me and i have not had any issues since. Ryan has earned my business and i will continue to use this dealership for any and all services my vehicle may need in the future.
