Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 X.
The 2021 Tesla X Electric is a battery-powered crossover built on the automaker's dedicated EV platform, pairing dual-motor all-wheel drive with the falcon-door utility that defines the model's identity. As a mid-cycle evolution of the second-generation architecture, it carries forward the large touchscreen-driven cabin and over-the-air update ecosystem rather than introducing a ground-up redesign. Reliability-wise, this model year sits in a problematic stretch of the X's history, with 24 recalls and 39 owner complaints on record—steering issues leading the complaint tally—making it one of the more scrutinized years and a vehicle any researcher should approach with careful attention to recall completion and service history.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2021 Tesla X lead in one area — the steering, 8 of 39 reports (21%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 3 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the steering pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
