Route 66 Auto Repair in Upland, CA measures customer satisfaction by what happens when something goes wrong. Comebacks go to the front of the line, the root cause is written on the repair order, we reply to reviews with facts and a phone number, and we only ask for a review after a clean pickup.
What is a comeback, and why does it go first?
A comeback is a car that returns because the repair did not fully fix the problem, or a new symptom appeared right after. It is the worst feeling for a driver: you paid, you trusted, and the noise is back on the drive home.
So comebacks skip the line. A technician looks at the car before new work, finds the root cause and writes it on the repair order. That record matters: it shows what actually happened and keeps the same mistake from repeating. What the warranty covers depends on the part and repair, and it is written on your invoice.
What should I do if a job missed?
Step 1: Call, don't wait
Call (909) 608-7699 and tell us what you are hearing or seeing.
Step 2: Bring the invoice
Bring the car and your invoice so we can match the original work.
Step 3: Root cause on paper
We inspect, find the cause, and write it on the repair order before anything else.
Step 4: Plain answer
A service writer explains what is covered on the invoice and what is not, before any new charge.
How do we handle reviews?
We ask for a review only after a clean pickup: the car is fixed, the bill matched the estimate and you left happy. We do not ask people in the middle of a problem, and we do not offer anything in exchange.
When a review is unhappy, we reply with facts from the repair order and a phone number, not arguments. Sometimes the reply is simply that we want to hear more. You can read what people say on our reviews page.
Which small habits prevent most complaints?
- Texting when a look window will slip, instead of going quiet
- Stating the diagnostic fee before testing, never at pickup
- Explaining two-technician labor before the clock starts
- Keeping declined items on the repair order so nothing is forgotten
- Road-testing the car before we call you


Frequently asked questions
How do I get back to you if I already have a work order?
Call (909) 608-7699 with your name and the vehicle, or bring the invoice to the counter. The repair order history lets a service writer pick up where the last visit left off.
What warranty do I get in writing after the repair?
Coverage depends on the part and the repair, and it is written on your invoice. Customer-supplied parts are not covered. See our warranty terms and ask at the counter if anything is unclear.
Will you ask me for a review?
Only after a clean pickup, and only once. If your visit did not go well, we would rather you call us so we can fix it.
