📋 Auto Repair Shop Negligence Claims in California

California's Automotive Repair Act provides strong consumer protections against dishonest and incompetent auto repair shops. The Bureau of Automotive Repair (BAR) regulates the industry and can revoke licenses, while you can pursue civil claims for damages caused by negligent or fraudulent repairs.

Types of Auto Repair Claims

🔧 Negligent Repairs

▼

When a mechanic fails to exercise reasonable care and skill, causing damage or creating unsafe conditions, you have a negligence claim. Examples include improper brake work leading to failure, incorrect torque specifications causing wheel loss, cross-threaded bolts, and using wrong fluids. The shop is liable for all resulting damages including corrective repairs, additional damage, and personal injuries.

💰 Unauthorized Work and Overcharges

▼

Under B&P Code 9884.9, shops cannot exceed the written estimate by more than 10% without your prior authorization. They must obtain your consent before performing any additional repairs. Violating these requirements entitles you to a refund of unauthorized charges. Keep all written estimates and compare them to final invoices.

🔍 Repair Fraud

▼

Repair fraud includes charging for work not performed, recommending unnecessary repairs, claiming false safety issues, and bait-and-switch tactics. This violates both the Automotive Repair Act and California's Unfair Competition Law (B&P 17200). Fraud claims may entitle you to treble damages and attorney's fees under certain consumer protection statutes.

📦 Parts Substitution Fraud

▼

Under B&P Code 9884.8, shops must clearly disclose if parts are used, rebuilt, or reconditioned. Charging for new OEM parts but installing used or aftermarket parts is fraud. Shops must also return replaced parts upon request (except warranty or exchange parts). Request your old parts before authorizing repairs.

⚠ Get a Second Opinion Before Paying

If you suspect a repair was botched or unnecessary, do not pay the bill without reservation. You can write "paid under protest" on the receipt. Have another qualified mechanic inspect the vehicle and document their findings before you lose evidence of the negligent work.
