First of all, the repair was to my knowledge was correctly done and the problem solved. This is most important. He was courteous and helped me see the condition of my brakes, which one could not do with a shop repair.
When you get away from that, there were multiple small problems. Some of these were with YourMechanic rather than Rod.
He arrived 20 minutes late, not counting the time going to the wrong address. He did not call first, as I requested, so I could call the gate. The YourMechanic software would not allow me to enter my address correctly; Customer Service couldn't do it either. They put a note on the ticket saying what the correct address was, but he hadn't seen it, so he went to the wrong address.
The estimate provided by YourMechanic indicated that the repair would take 2 3/4 hours. I thought this must be a really complicated repair (and the estimate seemed very reasonable for that, which is one reason I accepted it). He was done in an hour. I pointed this out to him and he had no explanation.
I did not think to ask if a new (as opposed to remanufactured) part was being installed, and so far I have not received a reply when inquiring of YourMechanic whether this was the case.
I was surprised that he wrote up an estimate for a further repair that I told him I was not doing now (replacing brake pads and turning rotors). He says in a report voice recording that I "refused" this repair. That is not what I remember, so we had a communications problem. He says in his recording that the left pads were 70% worn, although I don't remember that figure. But they definitely had considerable wear. The reason I am not doing a full brake job now, as I explained to him, is that this is a 2005 car with 117,000 miles on it, that is driven 3,000 miles a year, if that, and rarely over 40 mph.
What particularly irritated me was that the statement had five boxes that were to indicate the condition of various parts of the car. He checked all of them as "excellent". No one would ever say that the tires on this car were in excellent condition. They have 50,000 miles on them. What this means is that he just checked all the boxes that way to finish sooner and be off to his next job, and the excellent ratings are meaningless.
Finally, if you use YourMechanic you should be prepared for lots of emails, some of them repetitive, unnecessary, and unwanted. For example, after scheduling the repair, I received several emails encouraging me to do so.
