The 2024 EQE is still very early in its lifecycle, so long-term failure patterns aren't fully established. However, early adopters are seeing issues with the MBUX Hyperscreen system, thermal management components, air suspension complexity, and some build quality concerns typical of first-generation EVs from traditional luxury brands.
MBUX Hyperscreen Freezing and Pixel Failures
Occasional · medium severitySymptoms: Screen goes black or unresponsive, requiring hard reboot, Pixel lines or dead zones appearing in display, Climate and drive mode controls become inaccessible, Navigation and charging info disappears intermittently
Fix: Mercedes typically replaces the entire Hyperscreen assembly under warranty—it's not serviceable in pieces. Out of warranty, you're looking at a dealer-only part swap taking 4-6 hours including recalibration and software updates. Independent shops can't touch this yet due to proprietary tooling.
Estimated cost: $7,000-9,500
Heat Pump and AC Evaporator Refrigerant Leaks
Occasional · medium severityTypical onset: 15,000-35,000 mi
Symptoms: Reduced cabin heating or cooling performance, Battery preconditioning not working properly in cold weather, AC blowing warm air despite compressor running, Reduced range in extreme temperatures (heat pump not contributing)
Fix: The EQE uses a complex heat pump system for efficiency. Early units have seen refrigerant leaks at evaporator or heat exchanger connections. Dash removal required for evaporator access (8-12 hours labor). Heat pump components may need software recalibration after repair. R-1234yf refrigerant adds cost.
Estimated cost: $3,500-5,800
AIRMATIC Air Suspension Compressor and Valve Block Failures
Occasional · medium severityTypical onset: 20,000-50,000 mi
Symptoms: Vehicle stuck in one ride height, won't raise or lower, Suspension warning light with 'Visit Workshop' message, Compressor running excessively or making grinding noise, Uneven ride height side-to-side after sitting overnight
Fix: The AIRMATIC system on EQE is carryover tech from combustion models but integrated differently with the EV architecture. Compressor failures and valve block solenoid issues are showing up earlier than expected. Compressor replacement is 3-4 hours; valve block is 2-3 hours. Requires Star Diagnostics for coding.
Estimated cost: $2,200-4,200
Rear Subframe and Differential Mount Clunking
Common · low severityTypical onset: 10,000-30,000 mi
Symptoms: Clunking or thudding noise from rear on acceleration or deceleration, Sensation of drivetrain 'settling' when switching between drive and reverse, Metallic tapping noise over bumps from rear suspension area, More pronounced in single-motor RWD models
Fix: The rear subframe bushings and differential mounts appear undersized for the instant torque delivery of the electric motors. Mercedes has issued revised mounts with stiffer durometer rubber. Replacement takes 3-4 hours for subframe bushings, 2 hours for diff mounts. Often done together.
Estimated cost: $1,200-2,400
12V Battery Drain and Auxiliary Systems Failures
Occasional · high severitySymptoms: Vehicle won't wake from sleep mode, completely dead, Door handles won't extend, key fob unresponsive, Warning about 12V battery after sitting 3-5 days, High-voltage battery full but car won't start
Fix: Like all EVs, the EQE has a 12V lithium auxiliary battery that powers control modules. The DC-DC converter (charges 12V from main battery) can fail, or the 12V battery itself degrades prematurely. Battery replacement is 1 hour; DC-DC converter is 3-4 hours behind front fascia. Must be programmed to vehicle.
Estimated cost: $800-2,800
Body Panel Fit and Paint Quality Issues
Occasional · low severitySymptoms: Uneven door gaps, especially rear doors and quarter panels, Paint orange peel texture more pronounced than typical Mercedes, Door skin creaking or flexing when closing, Weatherstrip wind noise at highway speeds
Fix: Build quality on early EQE production (Tuscaloosa plant) has been inconsistent. Panel alignment issues typically require door hinge adjustment (1-2 hours per door) or in severe cases, quarter panel replacement (8-10 hours including paint). Most are warranty claims, but used buyers inherit cosmetic defects.
Estimated cost: $1,500-6,500
Regenerative Braking Inconsistency and Brake-By-Wire Faults
Rare · high severitySymptoms: Brake pedal feel changes unpredictably (soft then firm), Regen braking cuts out suddenly, requiring friction brakes, Yellow brake warning light with reduced stopping power, One-pedal driving mode disables itself randomly
Fix: The EQE uses a brake-by-wire system blending regen and friction. Software calibration issues and occasional hydraulic unit failures have been reported. Dealer-level diagnostics required. Hydraulic unit replacement is 4-5 hours; often resolved by software update first. Safety critical—address immediately.
Estimated cost: $3,000-5,500
Too new to call long-term reliability, but early issues suggest waiting for 2025+ model years or ensuring a strong warranty—indie repair infrastructure isn't there yet and parts are eye-wateringly expensive.
