Single Motor (EQS 450+)

• Loss of Power / “Turtle Mode”
  • Description/Symptoms: The vehicle suddenly enters a reduced power mode, sometimes referred to as “turtle mode,” limiting speed and acceleration. This can be caused by a software glitch affecting battery management or motor control. Some owners have reported this occurring unexpectedly during normal driving conditions.
  • Solution: A software update from Mercedes-Benz is typically required to address the underlying software issue. In some cases, a complete reset of the vehicle’s systems may be necessary.
  • Estimated Cost to Fix: $0 if under warranty, otherwise diagnostic fees may apply (potentially $200 - $400+) in addition to the cost of the software update (if applicable).
  • Recalls: None Found

Electrical

• 12V Battery Drain
  • Description/Symptoms: The 12V battery, which powers auxiliary systems, drains rapidly, leading to starting issues or system malfunctions. This can be caused by parasitic drain from a faulty module or improperly shut down electrical components.
  • Solution: Diagnosis involves identifying the source of the parasitic drain and replacing the faulty component.
  • Estimated Cost to Fix: $150-$1,000+, depending on the component needing replacement.
  • Recalls: None Found
• Hyperscreen Freezing/Malfunctioning
  • Description/Symptoms: The Hyperscreen, which integrates multiple displays into a single large unit, can freeze, lag, or exhibit other malfunctions. This can impact access to vehicle controls, navigation, and entertainment features.
  • Solution: Often resolved by a software update or a system reset. In some cases, hardware replacement of the Hyperscreen unit may be required.
  • Estimated Cost to Fix: $0 if under warranty, or $1,000 - $5,000+ if the hardware needs to be replaced outside of warranty.
  • Recalls: None Found

Exterior

• Sensor Malfunctions (Parking Sensors, Blind Spot Monitoring)
  • Description/Symptoms: Parking sensors or blind spot monitoring systems may provide false alerts, fail to detect obstacles, or become completely inoperative. This can be caused by sensor damage, misalignment, or software glitches.
  • Solution: Diagnosis involves checking sensor alignment, cleaning sensors, or replacing faulty sensors. Software updates may also address related issues.
  • Estimated Cost to Fix: $200 - $800+ per sensor, depending on location and complexity of replacement.
  • Recalls: None Found

Interior

• Malfunctioning Massaging Seats
  • Description/Symptoms: The massaging seats may fail to operate, provide uneven massage intensity, or make unusual noises. This can be caused by issues with the seat’s internal motors or pneumatic system.
  • Solution: Diagnosis involves inspecting the seat’s internal components and replacing faulty motors, hoses, or control modules.
  • Estimated Cost to Fix: $300 - $1,500+, depending on the specific component needing replacement.
  • Recalls: None Found
