JAKARTA - Mercedes-Benz, as one of the leading manufacturers in the face of the epoch of electrification, presents various variants of EV and hybrid models for its loyal customers, including plug-in hybrid (PHEV) and mild-hybrid.

However, amid its efforts to deliver leading hybrid technology, Mercedes-Benz is facing problems with the GLC 300 2023 model in the US.

The National Highway Traffic Safety Administration (NHTSA) is investigating the problems faced by GLC 300 2023. This issue is related to the 48V mid-hybrid system, which causes the engine warning light to turn on and the vehicle unable to turn on.

Reporting from Carscoops on Tuesday, August 1, NHTSA received a petition complaining of a flaw in the GLC 300 mid-hybrid system. One user reported that the engine died suddenly while driving and could not be restarted for more than 90 minutes, although it has been tried repeatedly. After that, the vehicle can be revived and run normally, but this problem reappears three times. When the problem occurs, the vehicle has a total distance of about 3,800 km.

Several other GLC 300 2023 users also reported similar problems, according to a Mercedes-Benz service manager.

The investigation is ongoing and will determine whether a recall is needed. If so, some 8,000 vehicles in the US may need to be repaired.

It should be noted that this is not the first problem that befell the GLC 2023 model. Previously, the GLC experienced a recall due to fuel pump problems at GLC 300 2021-2023, GLC 43 2021-2023, and AMG GLC 63 2021 in early July.
