Auto Repair Services GlendoraIgnoring a flashing red warning light, mysterious noises and leaks, or routine maintenance produces more than worry—it costs you money! Neglecting to perform routine scheduled maintenance can decrease a car’s fuel efficiency by as much as 15%, increasing that $4 gallon of gas to $4.60 per gallon. It won’t be long before you are spending hundreds of dollars you don’t need to. We are your one-stop auto repair shop for all of your car maintenance needs, performing all regularly scheduled factory maintenance including 3060, and 90K services as well as routine auto repair services such as oil changes and brake inspections.

Some of the many services we offer are:

  • Brake Repair: When your brake system is not working properly, the amount of friction required to slow your vehicle down is compromised, which means that you are putting yourself and precious cargo in danger! Our technicians are extensively trained and certified in brake system service and we will ensure the functionality of your braking system, and more importantly, your safety.
  • AC Service: Keeping your cool on Southern California roadways in summer is essential to comfort and the health of children and pets. Our ASE certified technicians will get to the bottom of refrigerant breakdowns that wreaks havoc on the entire AC system. As with all our repairs, we offer a 36,000-mile three-year warranty so you can rest assured you will stay cool when we get you back on the road.
  • Transmission Repair: As one of the most critical components in your vehicle’s engine, an optimally performing transmission is of the utmost importance. We have the technology and training to repair your transmission right the first time—and will be sure to recommend that you keep up with transmission fluid maintenance.

Whether you need an oil change or an engine replacement, come to the experts you can trust. We have been the top auto repair shop in Glendora for decades! Contact us online or call 626-541-2149 to make your appointment today.

The staff was very helpful and friendly. They communicated anytime there was something new that they would have to do. They also gave me an extremely fair price. The company, from what I have experienced, is very honest. Highly recommend.

Staff was very courteous and knowledgable. They took the time to explain exactly what was wrong with my car. They also went above and beyond, providing me a list of items that would be most beneficial to repair. Great price and service! Will be back again.

I first brought my car to Certified when another well-respected auto repair shop could not fix my problem after replacing over $1,000 in parts I apparently did not need. Certified quickly diagnosed the problem and made the repair for less than $200. I have been coming back for years and am very pleased.

In my search for a quality and honest mechanic for my VW Passat I came across Certified through the internet. They lived up to their great Five Star reputation. Outstanding and friendly service. I have found my car repair shop for the entire family. The staff is amazing. I highly recommend Certified Automotive.
