Auto repair estimate, invoice, and complaint check
A record check for an unexpected repair bill, work you did not approve, a smog-shop problem, or an unfinished repair.
Why it matters
The estimate shows the proposed work. Your approval lets the shop do it. The final invoice shows what was done. BAR uses all three in a complaint.
Official first stop
Cars and tickets
DMV fees, smog, titles, tickets, tolls, and car problems.
First moves
- 1
Write down the shop name, BAR number, VIN, and mileage. Add the dates, promised work, quoted price, and final charge.
- 2
Find the original estimate. A repair shop generally must prepare an estimate and obtain written, oral, or electronic authorization before beginning repairs.
- 3
For added work or charges, look for the new amount. The record should show who approved it, when, and how.
- 4
Compare the final invoice with the estimate and each approval. It should list the work, services, parts, and prices. It should also name the registered shop.
- 5
If you want replaced parts back, ask when authorizing the estimate. Exchange or warranty parts may be available only for inspection.
- 6
Save the estimate, work order, and invoice. Keep messages, call notes, warranty papers, photos, codes, smog results, and payment records too.
- 7
Ask the shop for a written explanation or correction if it is safe and practical. Keep the response rather than relying on a phone summary.
- 8
If it stays unresolved, file a BAR complaint. BAR may ask for records. It may try to mediate a refund, bill change, or repair.
- 9
Keep any warranty, card dispute, insurance, storage, lien, or court deadline moving while BAR reviews the complaint.
Watch for
- 1
A diagnostic tear-down is itself repair work and can carry a charge. It needs an estimate and authorization.
- 2
A note left with a vehicle after hours is not by itself authorization for repairs.
- 3
Towing and storage use separate rules. They may also have separate contracts and notices.
- 4
BAR handles registered repair dealers and smog-related work. A vehicle sale, dealer finance issue, manufacturer warranty, or safety recall can belong elsewhere.
- 5
Complaint mediation is not a formal enforcement case. BAR does not represent the customer in court.
- 6
Do not take or drive a vehicle that appears unsafe. Ask the shop to put safety concerns and release conditions in writing.
- 7
Get qualified help early for a large loss, injury, lien or storage threat, repossession, insurance dispute, or court deadline.
