Which Mercedes-Benz E-Class years should you avoid?
Avoid 2016 to early 2018 (W213) Mercedes-Benz E-Class models if you can. On the W213 (2016-2023), the years to avoid are the early diesels — 2016 to early 2018 — which were caught by the OM654 injector recall (2017-2019) and are more prone to AdBlue/NOx-sensor faults, plus harsher 9G-Tronic shifts before the 2019 software update. Verify by VIN that all recalls were done; injector or sensor work can run €800-€1,800 (2026).
Best and worst years to buy
Post-2020 examples have the OM654 injector recall fully completed, the 9G-Tronic gearbox software is matured, and MBUX 2 voice control is far more stable than initial release.

Before you buy or sell a Mercedes-Benz E-Class
Two quick checks pay for themselves on any used E-Class. First, check the car's NCT history before you buy — a missed or repeat-fail NCT often signals a chronic fault the seller is hoping you'll miss. Second, if you're weighing the E-Class against rival models, you can compare the E-Class against its rivals side-by-side on price, running costs and spec.
