2024 Mercedes-Benz GLE 450e 4Matic

Defect. Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2024 GLE 450e Plug-in Hybrid (PHEV) vehicles. Due to a software error in the electronic stability program (ESP), the force required to stop the vehicle may increase, possibly requiring an extended distance to stop.

Risk. Extended stopping distance can increase the risk of a crash.

Remedy. Dealers will update the ESP control unit software, free of charge. Owner notification letters were mailed on February 29, 2024. Owners may contact MBUSA customer service at 1-800-367-6372.

2024 GLE450: This engine has twin turbos. On second day of ownership a "yellow turtle" warning light appeared on dash. This indicated loss of significant engine power (i.e. hence the "turtle mode"). This happened, without warning, multiple times on highway during first few days of ownership. I think this means the turbochargers were "deactivated" or taken "off line" by vehicle's management system. Result was suddenly compromised ability while passing and ability to maintain highway speed to safe exit. Checked vehicle in to MB Service Department (on day five of ownership) for analysis and repairs. Vehicle subsequently in shop for 29 days!; 8/3/23-8/31/23 Repair order is more than two pages, single spaced. Appears dealer Service Dept ultimately "Replaced crank case vapor oil separator on top of valve cover." I tried to upload Service Invoice but wouldn't let me do it.
