Choose the part that went wrong: sale or title, repair paperwork, warranty or recall, or the loan and money side.
The short version
Dealer, private-sale, repair, warranty, and loan rules differ
Through September 30, 2026, many dealer-sold used cars under $40,000 must come with an offer to buy a two-day cancellation option. Private sales do not get that option; they start with title, smog, and the 10-day DMV transfer. The rest splits by office: BAR handles repair papers, DMV handles dealer conduct, NHTSA handles recalls, the manufacturer handles its warranty, and the lender handles the loan.
What changes the answer: California has no broad cooling-off period for car sales. The current two-day path works only when the buyer bought the written option and met its return rules.
California splits car problems among several offices. Sale papers, repairs, warranties, recalls, loans, and refund claims do not all go to the same place.
How it works
The current dealer option covers many cars under $40,000
A licensed dealer must offer the two-day option on a qualifying used car priced below $40,000. It does not cover a new car, private sale, motorcycle, OHV, RV, business-use vehicle, or a used car priced at $40,000 or more.
The option costs $75 up to $5,000, $150 from $5,001 to $10,000, and $250 from $10,001 to $30,000. From $30,001 to $39,999, it costs one percent. The fee is not refunded, but it counts toward an allowed restocking fee.
The current option has return rules
The car must return to the selling dealer by the contract time, usually close of business within two days. It must stay under the mileage limit, come with both receipts, remain in the same condition apart from normal wear or a new fault, and have no outside lien.
The restocking cap is $175 up to $5,000, $350 from $5,001 to $10,000, and $500 from $10,001 to $39,999. On an $18,000 car, the option costs $250 and the cap is $500, so the dealer must credit the $250 already paid.
A new return rule starts October 1, 2026
Starting October 1, 2026, many used purchases or leases at $50,000 or less get an automatic three-calendar-day return right. The three days start the day after the contract is signed. If day three falls when the dealer is closed to the public, the deadline moves to the next day it is open. Driving more than 400 miles can end the right.
The dealer may charge a restocking fee of 1.5 percent of the price, with a $200 minimum and $600 maximum. If the dealer charged to ship the vehicle, it may keep its actual shipping cost instead, up to that same limit. It may also add $1 for each mile over 250, up to $150. The rule excludes wholesale and unregistered vehicles, fleet sales, buyers who purchase five or more vehicles a year mainly for business use, vehicles rated at 10,000 pounds or more, motorcycles, auctions, and a lessee's purchase of the vehicle already in the lessee's possession.
Dealer add-ons must be clear
A dealer cannot add an optional product without disclosure and consent. The papers should list each add-on, its price, and the change to the monthly bill. Examples include a service plan, gap plan, theft device, paint product, and return option.
A car sold as certified needs a complete inspection report. A false odometer, some title brands, frame damage, an unsafe fault, an as-is sale, or a missing report can bar that label.
A private sale starts with title and smog
The private buyer has 10 days to transfer the title, and the seller has five calendar days to file the release form. When Smog Check is due, the seller gives a pass from the last 90 days. The dealer cancellation option does not apply.
A missing title, lien, false mileage, hidden damage, or broken promise can become a money dispute, while DMV mainly fixes the vehicle record. Save the ad, bill of sale, title, messages, payment, photos, and inspection history for any refund claim.
Each office handles one part
DMV licenses dealers and takes dealer complaints. BAR handles repair shops, estimates, approvals, invoices, and smog stations. NHTSA handles safety recalls, while the manufacturer handles warranty work. Lemon Law may help when a covered defect stays unfixed.
A loan or repossession issue starts with the contract and lender, and CFPB or DFPI may take a complaint. A regulator can review misconduct, but a refund or damages may still need arbitration, small claims, another civil case, or legal help.

First moves
- 1
Write down the VIN, plate, mileage, purchase date, and every name on the deal. Note every deadline you see.
- 2
Put every paper in one folder: title, contract, buyer's guide, ads, texts, financing, warranties, smog papers, repair orders, and photos.
- 3
Sort the problem before you complain. Record whether it was a dealer or private sale and whether the issue is the title, repair, warranty, recall, loan, or refund.
- 4
For a dealer sale problem, start with DMV's dealer complaint sources. Keep the dealer's written answer with your papers.
- 5
For a private-party sale, start with DMV's title and transfer steps. If the fight is about money back, also read the court self-help pages.
- 6
For repair, smog, or shop paperwork, start with the Bureau of Automotive Repair.
- 7
For a warranty or lemon-law question, start with the Attorney General's car page and the state arbitration program page. If real money or a deadline is at stake, get qualified help.
- 8
For a recall or safety defect, check the VIN with NHTSA and report the problem there.
- 9
For loan, credit, repossession, or add-on trouble, save the contract. Then use the official financial complaint source that matches the company.
- 10
If you mostly need money back, read the California Courts small claims pages before deciding your next step.
Watch for
- 1
A dealer sale and a private-party sale are not the same path.
- 2
Do not assume a cooling-off period. Check the DMV Car Buyer's Bill of Rights page first.
- 3
Dealer complaints, repair complaints, recall reports, and small claims cases do different jobs.
- 4
A clean-looking title, a passed smog check, and a working car are three different questions.
- 5
An as-is sale, a warranty, a service contract, a spoken promise, and a recall can each point to a different source.
- 6
Lemon-law and warranty questions turn on facts, repair history, and deadlines. Do not rely on a quick guess.
- 7
If the car is unsafe to drive, handle safety first before chasing paperwork.
- 8
Agency complaints build a record, but court and bank deadlines keep moving.
