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.

I spent a few weeks researching shops. I ended up working with Walter and Oscar on a cross-country purchase. GT performed a detailed pre-purchase inspection of a 22 year old vehicle that came back with comprehensive notes and details and pics. The work from GT ultimately fueled my decision to make a purchase. Very knowledgeable shop - everyone I spoke to clearly knows cars. Above all, the feedback and communication I received was above and beyond what I am used to, maybe it's time to move closer to this shop

I recently had the 12V auxiliary battery replaced on my Mercedes-Benz GLC 350e at GT. The experience was excellent from start to finish.GT began with a diagnostic battery test to confirm replacement was necessary, rather than proceeding on assumption. The initial quote was transparent, with no additional or hidden charges — the final invoice matched the estimate exactly.After installation, the technicians performed a post-service vehicle check. They noted a few prior low-voltage warnings in the system and advised these should clear following the new battery installation, which they did.Walter provided the service and was both highly professional and courteous throughout. I would recommend GT for hybrid electrical work based on the thoroughness, pricing transparency, and customer care demonstrated.

Spoke with Carlos about repairing a leaking main seal on our 2018 Mercedes Benz S560. He was very accommodating and they did an excellent job on the vehicle for less than half the price of the local dealership. The job took two days and I would recommend them for future work.

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.
