Mercedes-benz Gle 400 problems

Common Mercedes-benz Gle 400 problems

The Mercedes-Benz GLE 400 is a luxury SUV that has been praised for its strong engine choices and refined interior. However, like any vehicle, it is not without its common problems. Here are some of the issues that owners have reported with the Mercedes-Benz GLE 400:

• In-car Electronics: One of the most common problems reported with the GLE 400 is related to the infotainment system, including the audio, GPS, phone, rear entertainment system, backup or other camera/sensors, and head-up display. Owners have reported that the central command unit can go out, affecting all of the electronic dashboard features of the vehicle. This can happen at around 46,000 miles and can cost up to $6,000 to repair, even if it is partially covered by an extended warranty. Additionally, the screen can blank out, causing issues with the navigation and other features.

• Dead Batteries: Another common problem reported by owners of the 2019 GLE is dead batteries, which can show up within the first 10,000 miles. This is due to the many electrical accessories on the GLE that can drain the battery while the vehicle is off. Diagnosing the source of the parasitic draw can cost around $200 to diagnose and fix, while replacing the battery can cost around $500.

• Loss of Fuel Pressure: Some 2019 GLE owners have reported a loss of fuel pressure at around 25,000 miles, which can cause the engine to stall. This is due to a known weak spot in the fuel pumps, which can fail out of warranty and cost around $3,000 to replace.

• Stereo System Freezing Up: The stereo system can freeze up on some GLE models within the first 2,000 miles, but there are software updates available that can improve the reliability of the system. Most dealerships will install these updates for free as part of normal servicing, while others charge around $100 for the labor.

• Air Suspension System: The air suspension system can suffer expensive problems, although these are relatively few and far between. If you're looking at a car with the system fitted, it pays to make sure it rides smoothly, with no untoward harshness over bumps, and that you can feel the ride comfort change noticeably while you're on the move when you switch between Comfort and Sport modes. Also be wary of any suspension-related warning messages on the dashboard, such as 'Please wait, car is rising', which might come up when you start the car. These could point to leaks, which will take a bit of time to sort and could lead to a costly burnt-out compressor.

• Transmission Issues: Mercedes-Benz has recalled approximately 105,000 of its GLE mid-size and GLS full-size SUVs for faulty transmissions. The transmission may not downshift in certain conditions, causing the engine to stall and increasing the risk of a crash. Dealers will update the transmission control unit software for free to resolve the problem.

While these problems can be concerning, it's important to note that the GLE 400 has a reliability rating of 92.8%, which means that it is proving to be pretty reliable, with only 7% of cars suffering a fault. All issues were resolved at no cost to the owners, and all cars remained driveable and were repaired in less than a week. However, as with any vehicle, it's important to make sure that all the electrics function, the sat-nav does its job properly, and there are no concerning warning lights on the dashboard. It also pays to inspect the underside of your prospective purchase, to look for signs of off-road use such as scrapes or old mud. If it has such signs, it isn't necessarily a bad thing, but be aware of the potential for damaged components; you might want to get the underside professionally inspected before signing on the dotted line.
