Shop tricks worth knowing
None of these mean a shop is dishonest. All of them mean you should ask a question before you sign. Each one below comes with the line to say at the counter.
Padded shop supplies fee
Supplies should be a small flat charge or a few percent of labor. Anything above $50, or more than 5% of the bill, is margin dressed up as rags and gloves.
Diagnostic fee that never gets credited
A diagnostic charge is fair for the time spent finding the problem. Most independent shops waive it or apply it to the repair once you approve the work. Paying both is paying twice for the same hour.
The unnecessary flush
Brake fluid, coolant, power steering, and transmission fluid all have real intervals, and many modern transmissions are sealed. A flush recommended at every visit, with no mileage or condition given, is a revenue line.
Bundled labor billed twice
When two jobs share a teardown, the second job's labor should shrink. A serpentine belt while the alternator is out, a water pump with a timing belt, a thermostat with a coolant job. Full book time on both is double-billing.
The while-we're-in-there upsell
Filters, wipers, fuel system cleaners, and carbon cleaning services get added to a real repair because you're already saying yes. Each is easy to decline, and the cabin and engine air filters take five minutes to swap yourself.
Recall work you're being charged for
Open safety recalls are repaired free at any franchised dealer of that brand, forever. Independent shops sometimes quote the same component without checking. Run the VIN before you pay.
Dealer parts pricing without asking
OEM parts are fine, but quality aftermarket pads, rotors, filters, and sensors are often half the price and fully warrantied. A quote that never offers the choice is choosing for you.
Book time inflated
Labor is quoted from a flat-rate guide: a set number of hours for a job on your vehicle. Two and a half hours for a front brake job on a common sedan is high. Ask for the book time and the hourly rate separately.
Vague line items
"Brake service," "tune-up," and "electrical repair" hide what you're paying for. Every line should name the part, the labor hours, and the price. If it doesn't, you can't compare it and neither can we.
