2023 Mercedes-AMG C43 4MATIC — would a major price cut make you worry about resale?

ApexRunnerCommunity StarterJul 21, 20262023 Mercedes-AMG C43 4MATICDallas–Fort Worth
2023 Mercedes-AMG C43 4MATIC, about 48,000 miles. A manufacturer cutting MSRP or adding huge incentives is great if you're buying now, but painful for recent buyers. How much do you factor future price cuts into EV/luxury-car decisions? I'm in Dallas–Fort Worth. If I fix it I'll come back and update the thread. What am I missing?

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2023 Mercedes-AMG C43 charge sessions. I'd do that before spending real money. Did the worksheet show tax yet? If this is nothing, great. I want that in data.

Low-voltage gremlins will strand you even with a full pack. Try a second charger before blaming the 2023 Mercedes-AMG C43 — site sharing and pack temp change the curve a lot. I'd do that before spending real money. That's the whole play. If this is nothing, great. I want that in data.

That's a good start, but I wouldn't stop there. Try a second charger before blaming the 2023 Mercedes-AMG C43 — site sharing and pack temp change the curve a lot. That's where I'd start. Any freeze-frame data saved? This is the version I'd tell a friend.

I'd treat 12V warnings as a no-ignore. On the 2023 Mercedes-AMG C43, I'd get the 12V/DC-DC side checked even if the traction pack looks fine. That's where I'd start. On “amg c43 4matic — would a major,” that was the fork that mattered for me. This is from a 2023 Mercedes-AMG C43 in Dallas–Fort Worth with 48,000 miles. That's the whole play. This is the filter I use when the thread starts repeating itself. This is me being the wet blanket on purpose.

Then you'll know the next fork. I'd want a dollar figure or a measured spec, not 'should be fine.' If that fails I'll eat the diagnostic fee.

Don't clear the alert just to make the screen pretty. Leave the alerts on the 2023 Mercedes-AMG C43 so service can see what you saw. Then you'll know the next fork. Do that first. Not driving it hard until I know more.

This is from a 2023 Mercedes-AMG C43 in Dallas–Fort Worth with 48,000 miles. Monthly payment math is how wallets disappear. That's coming from doing this as an owner, not a shop. Only after sitting overnight so far.

Asking because it changes the advice: Try a second charger before blaming the 2023 Mercedes-AMG C43 — site sharing and pack temp change the curve a lot. I'd do that before spending real money. Stop there until you know. I'll update if anything new shows up.

I already checked the easy fluid levels.
