2018 Mercedes-benz Gle550e problems
The Mercedes–Benz M276 engine is a direct injected, gasoline automotive piston V6 engine.
The M276 engine is not related to the Chrysler Pentastar except for the 60 degree angle, despite that it was developed while Chrysler was still owned by Daimler AG. This can be seen in its 60 degree vee–angle, as opposed to the 90 degree angle of its M272 predecessor. The 60 degree vee–angle eliminates the need for a balance shaft, improving refinement while reducing mechanical complexity. None of the parts are shared at all.
The M276 engine features an aluminum engine block with Nanoslide cylinder coating and dual overhead camshafts with independent variable valve timing on 12 intake and 12 exhaust valves and a new 2–stage timing chain arrangement. The M276 also includes direct injection with piezo–electrically controlled injectors for 2 to 3 sprays per intake stroke in normal operation, multi–spark ignition that creates up to 4 sparks per cycle, and the demand–controlled fuel pump, water pump, oil pump and alternator that reduce parasitic loads.
The first spray of fuel injection creates the base lean burn mixture in the intake cycle, while the later spray(s), up to 4 more times in combustion cycle in difficult conditions for a clean burn, control when and where the ignition starts and how the burn propagates in stratified charge fashion. In combination with a new smaller and more efficient Variable Valve Timing mechanism on all 4 camshafts, the precise combustion control allows a quicker and smoother re–start of the engine for the stop–start system. This VVT can alter cam timing up to 40 crank degrees with a higher speed than before, and enables limiting the intake charge combined with a normal combustion stroke, thus making the operating process an Atkinson Cycle in partial throttle conditions for better fuel efficiency. These features are also shared with Mercedes' M278 V8 engine, announced at the same time.
Mercedes–Benz claims that the new engine, in conjunction with the demand–controlled ancillaries and the stop–start system, can produce up to a 24% improvement in fuel economy while increasing power and torque over the M272. This efficiency improvement led to the various models with this engine being labeled with Blue Efficiency moniker.
Retaining most of the above characteristics, turbocharged smaller displacement DELA 30 variant was introduced in 2013 for C400 (W205) and subsequently offered on other models without the name Blue Efficiency.
For 2014 CLS400, a turbocharged larger displacement variant named DELA 35 came out to the market with a lower boost of 0.7 bar (10 psi) compared to 1.8 bar (26 psi) of DELA30 resulting in the same power and torque ratings at a lower fuel consumption.
In 2015, a higher boost and a slightly lower compression ratio (10.5:1) were used to create a DE30LA version for AMG models, and is used for many AMG and Mercedes–Benz vehicles since.

Common 2018 Mercedes-benz Gle550e problems
The 2018 Mercedes-Benz GLE550e, a plug-in hybrid SUV, has been reported to have several common problems based on complaints from owners. Here are some of the issues and their details:
- Transmission Issues: Similar to engine issues, transmission problems have also been reported. One owner mentioned transmission issues, with the recommended solution being to select the gasoline-engine mode before beginning the commute. This issue might be due to the transmission's inability to handle the power distribution between the electric motor and the gasoline engine, leading to suboptimal performance and potential damage.
- Low Coolant Warning: Some owners have reported a low coolant warning that doesn't resolve after refilling the coolant. This issue might be due to a leak in the cooling system, which could lead to engine overheating and potential damage.
- Heating Steering Wheel: Some owners have reported issues with the heating steering wheel, which cannot be fixed despite multiple repair attempts. This issue might be due to a malfunctioning heating element or a wiring problem.
- Brake Issues: Some owners have reported premature brake wear, with one owner mentioning that the car needed entirely new brakes and rotors after less than a year of ownership. This issue might be due to the driving features of the vehicle, which could lead to increased brake usage and wear.
- Recalls: The 2018 Mercedes-Benz GLE550e has had several recalls, including a fuel pump issue that could cause an engine stall while driving and a roof panel issue that could detach from the vehicle. These issues could lead to safety concerns and potential accidents.
It's important to note that these issues might not affect all 2018 Mercedes-Benz GLE550e vehicles, and some of these problems might have been resolved through recalls or warranty repairs. However, potential buyers should be aware of these common issues and consider them when making a purchasing decision.
