Auto Repair, Maintenance & Diagnostics at NewGen Auto Repair
Our technicians work on everything from routine maintenance to engine and transmission jobs. We start with a computer scan, explain what the codes mean and give you a written estimate before any paid work begins.
Have an extended warranty or service contract? Bring your car to us. We work with extended warranty companies: we diagnose the problem, send the claim and photos to the warranty administrator and repair the car once the claim is approved. You pay only your deductible and anything the contract doesn't cover.
After a collision, we also scan for damage the impact may have caused to sensors, wiring and cooling systems, so nothing is missed in your insurance claim.

*Deductible assistance of up to $1,000 is available only on insurance claims where your insurance company has approved a repair amount of $8,000 or more and the repair is performed in accordance with that insurer-approved estimate (California Penal Code § 551(b)). We never increase a repair estimate to cover a deductible. Not available on customer-pay repairs. Ask us for details before your repair begins.
**Free computer diagnostic scan: we read and explain your vehicle's trouble codes at no charge, no purchase required. If the problem needs in-depth testing (labor), we give you a written estimate and get your approval before any paid work, as California law requires.
†Warranty: limited lifetime warranty on our collision, body and paint workmanship for as long as you own the vehicle; 24 months / 24,000 miles (whichever comes first) on mechanical repairs, parts and labor. Not covered: normal wear, new damage, abuse or neglect, rust or chips from road debris, and customer-supplied parts. Warranty terms are written on your invoice.
‡Accident towing: you pay nothing out of pocket when you have collision coverage or the other driver is at fault — we pay the tow and bill the insurance company. If no insurance covers the tow, we tell you the price before the truck is sent.
