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!

Brands like BMW, Mercedes, Audi, and Volkswagen often feature sophisticated cooling systems designed to maintain optimal engine temperatures under demanding conditions. However, when something goes wrong, these systems can develop issues that require prompt attention. Ignoring early warning signs can lead to overheating and costly engine damage. At G2 Automotive, we provide expert German cooling system repair in the greater Cumming area. Here are four common indications that your German car may need cooling system repair. Rising Temperature Gauge One of the most obvious signs of a cooling system problem is a temperature gauge that climbs higher than normal. German vehicles are engineered to operate within a precise temperature range, so even a slight increase can signal trouble. This may indicate a failing thermostat, low coolant levels, or a problem with the radiator. If the gauge continues to rise, it’s important to stop driving and have the vehicle inspected. Coolant Leaks/Low Coolant Levels If you notice puddles of coolant under your vehicle or frequently need to top off the coolant, you have a sign of a leak in the system. Leaks might develop in hoses, the radiator, or even the water pump. Low coolant levels can lead to overheating and serious engine problems if not addressed quickly. Steam from Under the Hood Seeing steam coming from under the hood is a clear sign that your engine is overheating. This can happen when coolant escapes or fails to circulate properly. Steam indicates that temperatures have reached a critical level, and continuing to drive can cause severe engine damage. Immediate attention is necessary in this situation. Unusual Smells/Sweet Odor A sweet smell coming from your engine bay often indicates leaking coolant. This odor is a strong sign that there’s a breach somewhere in the system. Even if you don’t see visible leaks, this smell should not be ignored.

When your BMW’s check engine light comes on, it’s a signal that something within the engine or emissions system needs attention. While BMW vehicles are known for their performance and engineering, they’re also sensitive to even minor issues. Ignoring the warning can lead to reduced performance and more costly repairs. At G2 Automotive, we provide expert BMW check engine light repair in the greater Cumming area. Here’s a look at four common BMW check engine light triggers. Faulty Oxygen Sensor Oxygen sensors play a key role in monitoring the air-fuel mixture. When an oxygen sensor fails, your BMW may develop worsening fuel-efficiency and increased emissions. A faulty sensor can also cause rough idling or sluggish acceleration. Replacing it promptly helps restore proper engine performance and prevents additional strain on other components. Mass Airflow Sensor Issues The mass airflow (MAF) sensor measures how much air enters the engine and helps determine the correct fuel injection level. When this sensor becomes dirty or malfunctions, it can lead to poor fuel-economy, rough running, or even stalling. Cleaning or replacing the MAF sensor can often resolve these performance issues. Ignition Coil or Spark Plug Problems BMW engines rely on precise ignition timing for optimal performance. Worn spark plugs or failing ignition coils can cause engine misfires, rough idling, and reduced power. These issues frequently trigger the check engine light and should be addressed quickly to prevent further engine problems. Catalytic Converter Failure The catalytic converter is responsible for reducing harmful emissions by converting exhaust gases into less harmful substances. When it becomes clogged or fails, your BMW may start to suffer worsening performance and decreasing fuel-efficiency. This is a more serious issue that should be addressed promptly at the shop.

The Mercedes brand is known for precise handling and advanced engineering. A major contributor to that performance is the suspension system. From traditional setups to advanced air suspension systems, Mercedes suspension components are designed for both luxury and control. When problems arise, repairs often require specialized knowledge and parts. At G2 Automotive, we’re happy to answer your questions about Mercedes suspension repair in the greater Cumming, GA area. What Are the Signs of Suspension Problems in a Mercedes? Common signs of suspension issues include a rough or bouncy ride, excessive body roll when turning, uneven tire wear, or the vehicle sitting unevenly. You may also hear clunking or knocking noises when driving over bumps. These symptoms indicate that components such as shocks, struts, control arms, or air springs may need attention. What Causes Mercedes Suspension Issues? Suspension wear is often the result of normal driving conditions, road impacts, and mileage. Potholes, curbs, and rough roads can accelerate wear on control arms, bushings, and ball joints. Also, worn shocks and struts naturally lose effectiveness as they age. Regular inspections can help catch minor wear before it develops into a larger problem. How Is a Suspension Problem Diagnosed? Technicians typically begin with a visual inspection of suspension components, checking for leaks, worn bushings, and damaged parts. They may perform a road test to evaluate ride quality and handling. For vehicles equipped with electronic suspension systems, diagnostic tools are used to scan for fault codes and assess system performance. Accurate diagnosis is essential to determine whether the issue involves shocks, struts, air springs, control arms, or other components. How Can I Extend the Life of My Mercedes Suspension? Routine maintenance and careful driving habits can help extend the life of your suspension system. Avoiding potholes and rough roads whenever possible reduces stress on components. Regular wheel alignments and tire inspections prevent uneven wear and additional strain. Addressing minor suspension concerns early prevents further damage. By staying proactive and seeking professional service when needed, you can maintain the smooth ride your Mercedes was designed to deliver. Where Can I Get Mercedes Suspension Repair in Cumming, GA?
