2023 Mercedes-Benz Gls 450 Recalls & Complaints

The 2023 Mercedes-Benz GLS 450 has 5 recalls, the most serious involving multiple issues that can cause sudden loss of drive power or an engine stall while driving, raising the risk of a crash.

Two separate recalls cover fuel pump failures that can shut down without warning and cut power to the wheels. A third recall addresses a transmission software issue where the gearbox may not complete a downshift in certain conditions, causing the engine to stall. There is also an electrical concern: a 48-volt ground connection located under the passenger seat may not be properly secured, which can cause it to overheat and start a fire. On the body side, rear door window trim bars can detach from the vehicle while in motion and become a hazard for other drivers.
