Official NHTSA text
Summary
Mercedes-Benz USA, LLC. (MBUSA) is recalling certain 2020 GLE350, GLE350 4MATIC, GLS450 4MATIC, and GLE450 4MATIC vehicles. The air conditioner drain hoses may have been incorrectly installed, causing water to drain from the air conditioner into the passenger compartment.
Consequence
If a significant volume of water enters the driver and passenger side foot wells, it might cause corrosion and/or short circuits to the electrical components in the area, increasing the risk of fire. In addition, the emergency call (eCall) feature may be disabled; the vehicle may not be able to be unlocked and/or started; and the engine limp-home mode might be activated during driving. These features increase the risk of an injury or crash.
Remedy
MBUSA will notify owners, and dealers will inspect and correct the air conditioner drain hoses, as necessary, free of charge. The recall began September 6, 2019. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2019080005.

Limitations

  • Complaint counts are owner reports, not verified findings or failure rates. There is no sales denominator.
  • Recall campaigns are listed for the model year. Only NHTSA and the automaker know whether a specific car was repaired.
  • Recent model years are still collecting reports.
