The Mercedes-AMG GT is a 2-door sports car that was first introduced in 2014. Developed by Mercedes-AMG as a successor to the SLS AMG, the GT aimed to provide the exhilarating performance and driving dynamics expected from AMG, along with the comfort, quality and practicality of a Mercedes-Benz grand tourer.
Powered by a handcrafted AMG 4.0L twin-turbo V8 engine, the GT produces up to 577 horsepower, allowing it to accelerate from 0-60 mph in just 3.7 seconds. However, with great power comes more stress on components, and the GT has proven prone to some issues over its lifetime.
Common problems span across engine, transmission, electrical, suspension, braking, interior, and exterior systems. Engine issues range from turbo and manifold leaks to premature engine bearing failure in some models. The 7-speed dual clutch transmission can suffer from jerky shifting, oil leaks and outright failure. The adjustable suspension components add complexity and potential problems. Brake issues like worn pads and rotors, sticking calipers, and leaks have been reported.
With supercar performance but grand tourer expectations, GT owners demand a vehicle that is both exhilarating yet reliable. But the added performance pushes some components to their limits. Being aware of potential issues can help owners prolong the enjoyment of their AMG GT. Proper maintenance and prompt repairs at the first signs of trouble will keep this super GT on the road.
Fuel Pump Issue
Owners can run into reduced performance on their Car from Low fuel pressure from failing fuel pump or clogged filter. Usually, these cars are susceptible to have their fuel pump fail early with less than 100,000 kilometers, which can cause troubles during acceleration and driving.
Engine Issues
The Mercedes-AMG GT is a high-performance sports car, which means its engine is put under a lot of stress. This can lead to some common engine problems over time.
Oil Leaks
One issue owners report is oil leaks from the engine. This is often caused by dried out gaskets and seals. The AMG GT uses a dry sump oiling system which circulates oil through external lines. The connections in this system can develop small leaks over time. Replacing the gaskets and seals can fix minor leaks.
Misfires
Ignition coil failures are a known issue on AMG GT models. This can cause engine misfires, rough running, and loss of power. Faulty coils need to be replaced. Using premium fuel and regular maintenance can help prevent premature coil failure.
Turbocharger Faults
On turbocharged AMG GT variants, the turbo is placed under extreme pressures. Turbos can fail over time leading to boost leaks, sluggish performance, and check engine lights. Replacing the turbocharger and boost piping is needed in severe cases. Proper turbo cooling and warmup can help extend its lifespan.
Getting these common engine issues addressed quickly is important to avoid further damage. Using a specialist like MySyara is recommended for Mercedes-AMG repairs and maintenance in the UAE. Their experienced technicians and factory training can accurately diagnose and fix problems.
Transmission Problems
The Mercedes-AMG GT is a high-performance sports car, so it’s designed to shift aggressively. However, some owners have reported issues with the 7-speed dual-clutch transmission being too rough.
The most common transmission problems include:
- Hard shifts – The transmission may jerk or slam into gear, especially when cold. This can make the car unpleasant to drive in stop-and-go traffic. Hard shifts indicate a problem with the transmission fluid pressure or worn clutch packs.
- Gear slipping – When accelerating hard under full throttle, the transmission may not fully engage the next gear. This allows the RPMs to flare up before the clutch engages and causes a delay in acceleration. Gear slippage usually means the transmission fluid needs to be changed or the clutch plates are worn.
Get your AMG GT transmission inspected if you notice any banging, jerking, or delay during shifts. Harsh gear changes or slippage under acceleration can quickly wear out internal transmission components. To prolong the life of your 7-speed transmission, change the fluid and filters according to the maintenance schedule. Delaying repairs will only make the problem worse.
High Repair Costs
The Mercedes-AMG GT is a high-performance sports car with a hand-built engine, so repair costs are significantly higher than average vehicles. Here are some key facts about the high cost of owning an AMG GT:
- Engine repairs often exceed AED 18,000+ due to the complexity of the twin-turbo V8 and tight engine bay. Replacing the entire engine can cost AED 80,000 or more.
- Transmission issues like replaceing the 7-speed dual clutch transmission can run AED 30,000 – AED 45,000. The AMG SPEEDSHIFT transmission is designed for hard launches and track use, so it tends to wear out faster than a normal transmission.
- Suspension components like control arms and shocks/struts wear out quicker on the AMG GT due to tight tolerances and firm suspension tuning. Plan on AED 8,000+ for full suspension repairs.
- The total 5-year cost of ownership for an AMG GT is approximately AED 385,000 according to Edmunds, far above the luxury sports car average of around AED 300,000. This includes higher insurance premiums, fuel costs, maintenance, and repairs.
Potential AMG GT buyers should carefully consider the higher long-term costs before purchasing this exotic sports car. While ownership provides thrilling performance and prestige, ongoing repair bills for a used Mercedes-AMG GT can strain budgets. Connect with a trusted European mechanic like MySyara in UAE to minimize repair costs.
Conclusion
The Mercedes-AMG GT is an incredible sports car that offers immense power and exhilarating performance. However, like any complex performance vehicle, it can suffer from reliability issues if not properly maintained.
Some of the most common problems reported in the AMG GT include engine problems like oil leaks, turbocharger faults, and carbon buildup. The 7-speed dual-clutch transmission can also encounter problems like jerky shifts, leaks, and premature wear.
Proper maintenance and care is crucial for the AMG GT in order to maximize reliability and longevity. Following scheduled service intervals, performing preventative maintenance, and addressing any problems promptly is highly recommended. For owners in the UAE, specialized German car shops like MySyara offer personalized service and expertise for AMG vehicles. Their experienced technicians and quality repairs can help keep your AMG GT running like new for years to come.
Investing in proper upkeep and partnering with a respected shop goes a long way towards enjoying the AMG GT without the headaches of constant repairs. With proper care, these hand-built performance machines can deliver exhilarating driving experiences for the long haul.
