The 2015-2016 Mercedes-AMG GLE 43 Coupe combines aggressive styling with high-performance capabilities, making it a favorite among luxury SUV enthusiasts. However, as with any high-performance vehicle, ownership comes with a unique set of maintenance requirements and potential issues. This article delves into the most commonly reported problems for the GLE 43 Coupe, tips on what to look for when buying a used model, and an overview of ownership costs to help you make an informed decision.
Common Problems with the 2015-2016 Mercedes-AMG GLE 43 Coupe
1. Air Suspension System Issues
One of the hallmark features of the Mercedes-AMG GLE 43 Coupe is its air suspension system, designed to provide both comfort and performance adaptability. However, the air suspension is prone to several issues. Over time, owners may experience a loss of ride height, often caused by leaking air struts or failing air compressors. If the system malfunctions, it can lead to an uneven stance or a “slumped” appearance on one side. This is not only an aesthetic concern but can also affect handling and stability.
Signs and Prevention: Symptoms of air suspension issues include uneven ride height, a harsh or bouncy ride, and warning lights on the dashboard. During a test drive, observe the suspension’s behavior over bumps and check for any warning lights. Replacing air suspension components can be costly, and although aftermarket options exist, they may not match OEM quality.
2. Engine and Turbocharger Problems
The AMG GLE 43 Coupe is equipped with a twin-turbocharged 3.0L V6 engine that delivers impressive power, but the turbochargers are known to have some vulnerabilities. Commonly, issues arise with the turbo seals, which can lead to oil leaks, or the wastegate, which can cause boost inconsistencies. These issues may result in reduced performance, poor fuel efficiency, or even damage to the engine if not addressed promptly.
Signs and Prevention: Symptoms of turbocharger issues include a noticeable drop in power, excessive smoke from the exhaust, and unusual high-pitched whining sounds from the engine. It’s essential to check for a history of regular oil changes, as well-maintained oil can help protect the turbos. For potential buyers, inspecting the engine bay for oil residue around the turbo area can provide clues about its health.
3. Transmission Slippage and Rough Shifting
The GLE 43 Coupe’s 9-speed automatic transmission generally offers smooth performance, but owners have reported occasional issues with rough shifting or slippage, especially at lower gears. This is often due to software calibration issues, which can sometimes be resolved through a reprogramming update from the dealership. In other cases, issues may stem from the transmission fluid degrading over time, particularly if the vehicle has been driven hard.
Signs and Prevention: Signs of transmission issues include rough or delayed shifts, jerking between gears, and transmission-related warning lights on the dashboard. When test-driving, pay attention to how the car shifts, especially in stop-and-go situations. Keeping up with transmission fluid changes and software updates can help minimize these issues, but extensive repairs can be costly.
4. Electrical System and Infotainment Glitches
The GLE 43 Coupe is packed with advanced electronics, but this can be a double-edged sword. Commonly reported issues include glitches with the infotainment system, such as screen freezing, lagging response, and occasional failure of navigation or Bluetooth functionality. Additionally, certain drivers report issues with the backup camera not activating or malfunctioning. These problems, while not typically critical, can be frustrating for drivers who rely on these systems.
Signs and Prevention: Signs of electrical issues include delayed infotainment response, unresponsive navigation, or system resets. To check for electrical integrity, test the infotainment system thoroughly during a test drive, including the Bluetooth, navigation, and backup camera functions. Addressing minor electrical problems early can prevent more serious issues from arising.
5. Brake Wear and Rotors
The AMG-tuned brakes on the GLE 43 Coupe are designed for high performance, but this can lead to quicker wear on both the brake pads and rotors. Drivers frequently report that the brakes require replacement sooner than expected, especially if the vehicle has been used aggressively. Replacing brakes on a luxury performance SUV is generally more costly than on standard vehicles due to the premium components used.
Signs and Prevention: Symptoms of brake wear include squeaking, grinding, or vibrations when braking. During a test drive, ensure that the brakes feel firm and responsive, and inspect the brake rotors and pads if possible. Regular brake maintenance is essential for both performance and safety, though it can be costly on a performance vehicle like the GLE 43.
6. Premature Tire Wear
The GLE 43 Coupe’s sporty design and weight distribution contribute to faster-than-average tire wear, particularly on performance-oriented tires. Owners report frequent tire replacement, especially on models with staggered setups where the front and rear tires are different sizes, making rotation difficult. This accelerated wear can lead to increased ownership costs over time.
Signs and Prevention: Look for uneven tire wear, especially on the inner edges of the tires. During the buying process, inspect the tire tread depth and consider whether recent replacements were made. Opting for high-quality tires can help with longevity, though they will add to overall maintenance costs.
7. Oil Leaks and Gasket Failure
While the AMG-tuned engine in the GLE 43 Coupe is built for performance, some owners have reported minor oil leaks, often due to failing gaskets or seals. Left unchecked, these leaks can result in oil seepage around the engine, which could lead to more significant engine problems over time.
Signs and Prevention: Look for oil spots under the vehicle and inspect the engine for any visible oil buildup around the valve covers or turbochargers. Proper maintenance and using the correct type of oil are essential, as neglecting oil changes can exacerbate gasket wear. Prospective buyers should ask about the vehicle’s oil change history.
Buying Tips: What to Look for in a 2015-2016 Mercedes-AMG GLE 43 Coupe
Service Records: Given the AMG performance tuning, it’s essential to review the vehicle’s full service history. Confirm regular oil changes, any turbocharger maintenance, and check for recent brake replacements.
Suspension and Ride Height: Carefully inspect the air suspension’s condition and confirm there are no leaks or warning lights. Test-drive the car over various road conditions to observe any unusual handling or ride height issues.
Infotainment System and Electronics: Test all electronics, including infotainment, navigation, Bluetooth, and backup camera, to ensure they’re functioning correctly. Electrical repairs can be time-consuming, so it’s best to identify any issues before buying.
Check Tire Condition: Examine the tire wear and tread depth. Given the GLE’s reputation for premature tire wear, new or recently replaced tires are a plus.
