WE PUT OUR CUSTOMERS FIRST

I have been using GT automotive for over 10 years. Recently, we were having brake issues with a Honda Odyssey. We took it to a dealer to fix since recalls and had them look at the brakes as well, out of convenience. They were dishonest about cost and used bait and switch tactics regarding fixing our brakes. I ultimately refused service and took it to GT. They had the car in and out within half a day, were honest about cost, didn’t charge exorbitant shop costs above cost of service, and communicated throughout the whole repair. I have found that type of care to be their standard. I have taken four cars for service and never had an issue with the fix afterwards. I trust their mechanics and service completely. I cannot recommend them highly enough.

Ethan and his team at GT are so incredibly accommodating, knowledgeable and helpful. They are quick to diagnose and give a repair plan, never pushy about anything, just honest and want your car to be a safe and efficient on the road and for you to have peace of mind. You can absolutely trust to pay an absolutely fair price for truly exceptional services, including a courtesy loaner car so that while your car is being worked on, you’re not left without a vehicle. We have brought in my 2014 Subaru crosstrek multiple times for mostly maintenance and small repairs and have been helped with almost an entire rebuild on my boyfriends 2004 Chevy Astro, and it shows that this team of mechanics have great range when it comes to taking care of literally any vehicle.As a woman, it’s been really great to know that if anything goes wrong with my car, I don’t have to be afraid of taking it in and being dismissed for having questions or not understanding or getting unnecessary repairs. I know this team will always break it down for me and recommend what is best, and I recommend them to all of my family and friends.Thank you!

Took my Tacoma in for some work and I couldn’t be happier. Ethan and team did a great job with a quick turn around. Pricing was also on point. I will be recommending this shop to all my friends.

Ethan helped us fix my AC and back brakes. This is one of the only places I’ve been where they honestly help you. Ethan told me exactly how much life my brakes had and that I could wait, where most shops would just try to make you fix it that day. Really appreciate this and the team. Highly recommend!

GT Automotive went above & beyond to make sure we were able to get our auto part needed via our extended warranty, which took many hours on the phone and shopping for parts. They kept us well updated along the way. They allowed us to keep our car parked in their lot for several weeks during the wait on the approval and for parts to arrive. Thank you Mandi & Ethan. Highly recommend GT Automotive!

Top notch communication and friendliness. Only reason for not giving the extra star, we’ve only had the car back 1-2 days. But I’m sure the work was good.

Common Electrical System Issues in Porsches

Porsche vehicles are known for their high-performance capabilities and luxury features, but all of these features come with a complex electrical system—and complexity often leads to issues. 

Some of the most common issues seen in Porsche vehicles include faulty headlights, dead battery, weak alternator, power windows not working correctly, short-circuiting, audio system malfunctioning, and more.

Performing Diagnostic Service on Your Vehicle

At GT Imports Automotive Repair we know how important it is to stay on top of your vehicle’s maintenance schedule. To diagnose any potential issues or malfunctions in your vehicle’s electrical system our technicians use specialized tools such as oscilloscopes and multimeters to measure current output levels and analyze circuit configurations. 

We also utilize scanning equipment that can read data from the onboard computer systems so that we can accurately pinpoint the source of any problems that may arise.

Common Repair Solutions

Once our technicians have identified the issue they will then determine the best solution possible. This could involve anything from replacing a fuse or a broken wire to replacing an entire component such as a headlight or alternator unit. 

In some cases it might even require reprogramming certain components after replacement has been completed. Depending on the severity of the damage, repairs could range from simple DIY tasks to more extensive services that require professional assistance from qualified auto mechanics like those at GT Imports Automotive Repair.
