2020 Mercedes-Benz E-Class — what changed after 100k miles?

V8Collector191Community StarterAug 21, 20262020 Mercedes-Benz E-Class E450Denver
2020 Mercedes-Benz E-Class E450, about 59,500 miles. The car has crossed 100k and still drives well. I want to stay ahead of age-related failures instead of waiting for roadside problems. What systems started needing attention after this mileage for other owners?

I'd keep this practical. Verify the cheap/easy branch on the 2020 Mercedes-Benz E-Class before a big repair or a big spend. I'd do that before spending real money. This is from a 2020 Mercedes-Benz E-Class in Denver with 59,500 miles. Do that first. I've seen both outcomes, which is why I'd test instead of assume. I'll update if anything new shows up.

Write down what you already tried. A second data point from another 2020 Mercedes-Benz E-Class owner helps more than a generic diagnosis. I'd do that before spending real money. That's the whole play. I'd sleep better after that step, even if it finds nothing. If this is nothing, great. I want that in data.

Same neighborhood, different next step: A second data point from another 2020 Mercedes-Benz E-Class owner helps more than a generic diagnosis. Then you'll know the next fork. This is from a 2020 Mercedes-Benz E-Class in Denver with 59,500 miles. Happy to compare notes if your setup is different. Might be overthinking it, but I'd rather overthink than overspend.

Thanks — that narrowed it. I'm going to try the simpler check on the 2020 Mercedes-Benz E-Class first. I'm in no rush to be a hero on it.

Owner notes beat generic advice here. On the 2020 Mercedes-Benz E-Class in Denver, I'd fix the thing you'll notice every day before chasing spec-sheet extras. Then you'll know the next fork. On “benz e-class — what changed after 100k,” that was the fork that mattered for me. Do that first. I'd rather look cautious in this thread than stuck later.
