Is There a Problem with the Battery in the 2021 Mercedes-Benz GLE?

Yes, the National Highway Traffic Safety Administration (NHTSA) has logged several consumer complaints from vehicle owners regarding a battery issue in the 2021 GLE. More specifically, the battery fails causing the vehicle to not start, inconveniencing owners.

Mercedes-Benz issued a technical service bulletin for this problem, NHTSA ID Number10189404, on February 19, 2021. The TSB lists the possible causes along with remedies for each. Of the five possible listed causes, two are software related, one is hardware related, one is a cooling issue and the last is a false-positive detection error which causes the “48V battery to disconnect itself.”

Depending on the cause, the vehicle may:

  • Not start
  • Display a yellow or red instrument cluster notification regarding the 48V battery
  • Trigger “limp home mode” as well as overheating, loss of acceleration or A/C not working correctly

What Battery Problems are 2021 GLE Owners Experiencing?

Many complaints state that the battery in their 2021 GLE dies causing the vehicle to not start. In other cases, owners experience a 48V battery warning light on the dashboard or in more severe cases, loss of acceleration while driving or overheating. Here’s a look at some of the complaints:

An owner from Massachusetts states:

“The contact owns a 2021 Mercedes-Benz GLE450. The contact stated while driving at various speeds the vehicle loss motive power. The 48V battery malfunction and coolant hot turn-off vehicle message were displayed on the instrument panel. The battery indicator warning light was illuminated. The vehicle was taken to the local dealer and diagnosed with a software issue. The contact was informed that the software needed to be updated. The vehicle was repaired however, the failure recurred. The manufacturer was not notified of the failure. The approximate failure mileage was 3,000.”

An owner from Maine filed a complaint on the NHTSA website stating:

“There are numerous reports of the 48v battery failing on multiple Mercedes models using the 6 cylinder with ISG engine. Mercedes should do a recall to replace all 48v batteries as this problem makes the cars unreliable and unsafe to use as sometimes this 48v battery system fails while driving.”

Other owners have similar complaints:

“The 48v battery after driving new vehicle only 230 miles goes dead. The auto will not start and cannot be jump started. Result is being stranded roadside. Required a tow. Mercedes says dead battery (brand new) needs to be replaced. Battery went dead on December 10. Dealer tells me no batteries are available in the us….”

“GLE53 would not start. The car threw an error stating 12v battery malfunction.(Impacted the 48V battery) This essentially disables the vehicle completely….”
