I have a 2019 GLC43 and the warranty is almost up, so I've been thinking of trading to a 2022 .......are there any big differences in the two years, besides the 22 having a little more HP?

I don't know the answer, but it seems like getting an extended warranty (through MB or otherwise) would make more sense, no?

The big one is the change to MBUX and some interior updates. MY22 will be the last with the M276 and TTV6 engine.

Well, quite a bit actually going from pre-facelift GLC to facelift GLC.

The headlight (84 leds from the E-Class if you option the highest one), grille, taillight are all different. As you mentioned, horsepower increase and as others mentioned MBUX and interior updates such as steering wheel changed, optional digital instrument cluster, optional Drive Unit, different optional wheel designs, more comfortable tuned suspension, 64 ambient light colours instead of just three, wider centre screen, engine seems to run cooler and coolant operating temperature seems to be lower as well, trackpad replacing the previous touchpad in the centre console to name a few.

Here is the list I came up with the changes I noticed before (it is for the W205 but many applies to the X253 as well), hopefully it helps you: https://mbworld.org/forums/c450-c43-...ml#post8411480

As for point 18, it doesn't apply to you as you get MBUX not COMAND, which means you get NTG 6.0

@stangd1909 How many miles are on the vehicle? I post extended warranty costs from both Fidelity and Freedom Warranty for you to consider with your decision.

Looks like one more year for the TTV6 but in the GLC Coupe only. They are popping up on Autotrader.
