I bought a used truck from AutoNation Chevrolet in Peoria and within a day it was leaking a lot of DEF and wouldn’t REGEN. Took it back and it sat at the dealership for 3 months and they didn’t fix anything. So, I took it to David at Deer Valley Diesel and once it was next to get diagnosed and repaired the truck was fixed and running top notch in less than 2 days, start to finish!

Excellent service and excellent communication from them! Tough to beat that kind of service!
