Tesla Model X I facelift (2021 – 2025)

Reliability score : 7.2/10

The first-generation Tesla Model X received a major facelift in 2021 (often referred to internally as Project "Palladium"). This facelift features a completely redesigned interior (horizontal central screen, optional Yoke steering wheel, removal of stalks), improved sound insulation, and revised powertrains offering increased efficiency and performance. Important clarification regarding your request: You asked to target the diesel engine. It is imperative to specify that Tesla has never produced an internal combustion or diesel vehicle. The Model X is a 100% electric SUV. This sheet will therefore cover all the actual (electric) powertrains available for this model, in accordance with the manufacturer's technical reality.

✅ Strengths

⚠️ Weaknesses

🎯 Verdict

The facelifted Tesla Model X (2021+) remains a technological UFO. Its performance, onboard space, and charging network make it an excellent electric family SUV. However, its mechanical complexity (Falcon doors, suspension) and the fragility of its running gear given the power delivered (half-shafts, tires) require a rigorous inspection before purchase. Reminder: there is no diesel version. Favor a model still under manufacturer warranty (4 years/80,000 km for the vehicle, 8 years/240,000 km for the battery/motors) to avoid astronomical repair costs.
