Summary
The Mercedes-Benz E 450 has 8 recalls spanning 2017 through 2022, with the most serious being a failure of the pre-crash tensioning system and seatbelt pretensioners on 2018-2019 models that may not activate in a crash, leaving occupants less restrained at the moment of impact.
Recalls 2 and 6 share the same severity level and cover the 2019 model year. On 2019 Coupe and Cabriolet trims, a separate seatbelt tensioning system can also fail to activate in a crash. On the 2021-2022 model years, the 12-volt battery can lose charge under certain conditions, disabling the emergency call system, hazard lights, electric seat adjustments, and automatic door locks. On 2020 models, two occupant protection issues emerge: the front left seatbelt on Coupe trims can contact sharp metal edges during routing and develop damaged webbing that may not hold an occupant in a crash, and the left-rear seatback latch on vehicles with electrically unlatchable rear seats may not be strong enough to resist cargo loads, allowing the seatback to fold forward in a crash. Going back to 2017-2019 Wagon trims, the rear spoiler on 4MATIC and AMG Wagon variants can detach while driving and become a road hazard for other vehicles. The 2018-2019 Coupe and Cabriolet trims have tires marked with an incorrect maximum inflation pressure, meaning tires inflated to the stated limit may not have adequate strength and can fail at speed.
