Tien showed up on time and even though it was about 100 degrees in the driveway he immediately got to work on the car. He was very professional and I felt like I was in good hands. I would not hesitate using Tien and YourMechanic on my next service.

Alex was friendly and listened to my description of the problem. After working on it for 30 minutes, he told me that he got it started but was not able to diagnose the ignition problem. He told me that the van has an intermittent electrical failure which causes the problem of dash lights not coming on and engine not cranking. when turning ignition switch/key. Needless to say that I am not happy that​ a diagnosis could not be made at this time.
