Customer for 6 years

G2 customer since 2015. Brought my C-class back again for an oil leak initially repaired last month. They took care of me and just charged for the new part even though fix was difficult due to location. Gary is a great guy - very knowledgeable and trustworthy. Janna runs the office well and Bali is a world-class Mercedes tech.

I drive an hour to G2 for service

I swear by G2 Automotive. I have an older BMW 128i and anytime I have issues, they take care of me. They're so much cheaper than the dealership, however, does the same quality work. Thank you, Janna, Gary, and Jon., You guys really rock! It may take an hour to get to your shop, but it’s worth my time!

That one repair shop you can trust every time

My car had trouble while in Nashville. The repair shop there did $2,000 worth of work and still couldn’t get it running right. They proposed another $2,000 worth of work to finish the job. Instead, I had it towed home to G2 Automotive. They fixed it for $250. I am pursuing a refund from the shop in Nashville.

Always 100%

We've had some continued issues with our VW Tiguan... but they've been so great about assessing and helping resolve the warning lights. They've gone over and above to make sure we have a reliable car for our kids. G2 is the best!

Great shop!

I just purchased a used Jaguar like the one I had several years ago. I was happy to be back in a car I enjoyed until....... After 1 week the suspension light came on. I researched shops and decided on G2. That was a very good choice!!! The entire team at G2 was amazing! Jana is a dream to deal with at the front desk. Gary, the owner is always available and willing to talk. I had a chance to speak with two of the technicians, Grant, and Jon and both were more than willing to explain what they found and what repairs were needed. The entire team at G2 are honest and caring. In short order they repaired my car and got me back on the road. They are fair and get it right the first time! Thanks Gary and team!

The entire staff at G2 is top notch. These guys stand behind their work and have always treated me like a VIP. I highly recommend taking your car to G2 for all of your service and repair needs.

4 Common Reasons that German Vehicles Overheat

By G2 Automotive • September 4, 2026
German vehicles are known for their engineering and performance, but they can still develop cooling system problems that cause the engine to overheat. BMW, Mercedes, Audi, and other makes often use sophisticated cooling systems with multiple components that must work together properly. When one of these components begins to fail, engine temperatures can rise quickly. Recognizing the common causes of overheating can help you address problems before serious engine damage occurs. At G2 Automotive, we provide expert German cooling system repair in the greater Cumming area. Here’s a look at four common reasons that German cars overheat. Low or Leaking Coolant One of the most common reasons a German vehicle overheats is low coolant. Coolant absorbs heat from the engine and carries it to the radiator, where the heat can be released. A leak from a hose, radiator, water pump, or another component can gradually reduce the coolant level. If the engine doesn’t have enough coolant, it may not be able to maintain a safe operating temperature. Failing Water Pump The water pump circulates coolant throughout the engine and cooling system. If the pump becomes worn or fails, coolant may not move properly, allowing heat to build up. Some German vehicles use electrically controlled water pumps that can experience electrical problems. Warning signs can include overheating, coolant leaks, unusual noises, and cooling system warning messages. Thermostat Problems The thermostat regulates coolant flow based on engine temperature. When the engine is cold, it remains closed to help the engine reach its normal operating temperature. Once the engine warms up, the thermostat opens to allow coolant to circulate through the radiator. A thermostat that becomes stuck or fails to operate correctly can restrict coolant flow and contribute to overheating. Radiator or Cooling Fan Issues The radiator plays a critical role in removing heat from engine coolant. Damage, internal restrictions, or external debris can reduce its ability to dissipate heat. Cooling fans are also important, particularly when the vehicle is idling. A failed fan motor, for example, can prevent adequate airflow through the radiator and cause temperatures to rise.

Why is my German car struggling to start? A look at 4 common culprits

By G2 Automotive • August 5, 2026
Makes such as BMW, Mercedes, Audi, and Porsche deliver an outstanding driving experience, but like any vehicle, they can develop starting problems over time. If your engine cranks slowly, struggles to start, or won't start at all, it's important to have the issue diagnosed promptly. At G2 Automotive, we provide expert German vehicle diagnostics and repair in the greater Cumming area. Here are four common causes of starting problems in German vehicles. Weak or Failing Battery A weak battery is one of the most common reasons a German vehicle experiences hard-starts or no-starts. Modern European vehicles rely on numerous electronic systems that place a constant demand on the battery. As the battery ages, it may no longer provide enough power to start the engine reliably. Symptoms often include slow engine cranking or clicking sounds when attempting to start the vehicle. Faulty Starter Motor The starter motor is responsible for turning the engine over when you start your vehicle. If the starter begins to fail, you may hear a single click, repeated clicking, or no sound at all when pressing the start button or turning the key. A professional diagnosis can determine whether the starter or another component in the starting system is responsible. Fuel Delivery Problems Your engine must receive the proper amount of fuel to start and run efficiently. A failing fuel pump, clogged fuel filter, malfunctioning fuel injectors, or fuel pressure issues can prevent adequate fuel from reaching the engine.You may notice extended cranking, hesitation, or complete no-start conditions. Prompt fuel system repairs can restore reliable starting and improve overall engine performance. Ignition System Issues German vehicles depend on a properly functioning ignition system to ignite the air-fuel mixture inside the engine. Worn spark plugs, failing ignition coils, or damaged ignition components can make the engine difficult to start or prevent it from starting altogether. Misfires, rough idling, and poor acceleration often accompany ignition problems. Routine maintenance helps keep these components performing reliably.

Planning a road trip in your German luxury vehicle? Here are 5 important tasks the mechanic can complete before you depart

By G2 Automotive • May 27, 2026
Whether you drive a BMW, Mercedes, Audi, or Porsche, proper preparation is essential before taking your vehicle on a long road trip. These vehicles are finely tuned machines that benefit greatly from preventive maintenance and thorough inspections. The mechanic can help ensure your car is ready for extended driving conditions, reducing the risk of breakdowns and improving overall performance. At G2 Automotive, we provide expert German auto maintenance in the greater Cumming area. Here are five ways the mechanic can get your German luxury vehicle road-trip ready. Perform a Full Diagnostic System Check Modern German vehicles rely heavily on advanced onboard computer systems that monitor engine performance, emissions, and safety features. The mechanic can perform a complete diagnostic scan to identify any stored error codes or hidden issues. Even minor alerts can indicate developing problems that should be addressed before a long trip. This step helps ensure all systems are functioning properly. Inspect and Service Fluids Proper fluid levels and condition are critical for high-performance engines. The mechanic can check and top off or replace essential fluids such as engine oil, coolant, transmission fluid, brake fluid, and power steering fluid. Evaluate the Cooling System Long road trips place added stress on the cooling system. The mechanic can inspect the radiator, hoses, thermostat, water pump, and coolant condition to ensure the system is working efficiently. Because overheating can cause major engine problems, it’s crucial that the cooling system is functioning correctly. Check Braking and Suspension Components Smooth handling and responsive braking are essential during long drives. The mechanic can inspect brake pads, rotors, calipers, shocks, and suspension components for wear or damage. Addressing any issues before a trip helps maintain comfort and control. Test Battery and Electrical Systems German luxury vehicles rely heavily on electronic systems for navigation, safety, and performance features. The mechanic can test the battery, alternator, and electrical connections to ensure consistent power delivery. Proper testing helps ensure all systems operate reliably throughout the trip.
