2023 Mercedes-Benz GLC problems: engine and transmission complaints and recalls
ELEVATED COMPLAINT SIGNAL
34%
20 of 58 relevant owner complaints are about the engine, transmission or fuel system
34% of relevant owner complaints on the 2023 Mercedes-Benz GLC are about the engine, transmission or fuel system. That is elevated. Worth an independent inspection before you commit to one.
Better than 63% of the 1,789 model years we track (2010–2023).
Excludes 7 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 31%).
Does the 2023 Mercedes-Benz GLC have engine problems?
More than most. The pattern is elevated rather than severe. 20 of 58 relevant complaints filed with NHTSA about the 2023 Mercedes-Benz GLC concern the engine, transmission or fuel system (34%), and the largest group is filed under engine (15). For comparison, the 2022 scores 36%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

Before you buy a 2023 Mercedes-Benz GLC
Ask the seller whether the engine has ever been repaired or replaced, and whether the car has shown stalling, loss of power, rough idle, oil consumption or a check-engine light.
Drive it from a cold start and long enough to warm up. Many engine faults hide once the car is warm.
Get an independent pre-purchase inspection from a mechanic you choose, and tell them to focus on the engine.
Ask for service records. A engine already replaced under warranty is a different car from one that was not.
