2021 Tesla Model X Common Problems by Component
38 owner complaints grouped by vehicle system.
STEERING
12 complaintsOwners report frequent steering issues with the 2021 Tesla Model X, particularly involving loss of power steering and steering lockup. Complaints commonly describe symptoms such as heavy steering, steering assist reduction warnings, and total steering failure, often requiring significant force to regain control. These issues typically occur around 8,000 to 55,000 miles, with several owners noting repair costs around $5,000 for steering system components. Safety implications are significant, as multiple reports include near-accidents due to sudden steering failures, with some incidents occurring at highway speeds. Prospective buyers should be aware of these steering-related problems and the potential for costly repairs.
UNKNOWN OR OTHER
7 complaintsOwners of the 2021 Tesla Model X frequently report issues related to screen failures and software problems. Multiple complaints describe the touchscreen and instrument panel going black while driving, leaving drivers without visibility of speed, signals, or other critical information. These incidents are noted to occur both while parked and at highway speeds, suggesting a recurring issue. Additionally, some owners report persistent "Park Assist unavailable" errors and loud beeping during normal driving, which they find distracting. Complaints also mention repeated 12v battery discharges and a case of the accelerator pedal detaching, which impede vehicle operation. These issues are reported across various timelines, with no specific mileage pattern emerging. Safety implications include potential distraction from frequent error alerts and the inability to access essential vehicle information while driving.
SUSPENSION
6 complaintsSafety-relatedOwners report issues with the suspension system of the 2021 Tesla Model X, frequently mentioning control arm failures. Symptoms include unusual noises, such as clicking when turning, and excessive tire wear, with some owners indicating the inner front tires wore down to the steel belt within 9,000 miles. Complaints often highlight the failure of the front upper control arm, and one mentions a lower control arm snapping, leading to a wheel detachment. There are reports of crashes and injuries, with one incident involving sudden unintended acceleration resulting in a collision with a tree. These issues suggest potential safety risks, including loss of control and tire blowouts, particularly if the vehicle is not regularly inspected.
ELECTRICAL SYSTEM (6 complaints)
ELECTRICAL SYSTEM
6 complaintsSafety-relatedOwners of the 2021 Tesla Model X frequently report issues with the vehicle's computer system shutting down unexpectedly while driving, which affects the operation of screens, turn signals, and driver-assist functions. These shutdowns often last for a few minutes, during which critical systems like the speedometer and autopilot become non-functional. Some complaints mention this problem occurring multiple times within a few months of ownership. One report includes a crash where the vehicle suddenly accelerated and struck a charging station, resulting in an injury and non-deployment of airbags. Buyers should be aware of these electrical system issues as they may impact vehicle safety and require costly repairs.
VISIBILITY/WIPER (2 complaints)
VISIBILITY/WIPER
2 complaintsOwners of the 2021 Tesla Model-X report two main issues within the visibility/wiper category. One complaint describes a windshield defect where a mottling effect becomes apparent when driving into the sun, potentially causing temporary blindness. Another issue involves the windshield cracking during defrosting, with Tesla representatives advising owners to warm the vehicle before using the defroster. Both issues are noted by multiple owners, suggesting a broader pattern. There are no specific mileage ranges mentioned, but the safety implications include visibility impairment and the risk of windshield shattering while driving.
POWER TRAIN (2 complaints)
POWER TRAIN
2 complaintsOwners of the 2021 Tesla Model-X report issues with the power train, specifically involving the front half shafts and unusual noises during acceleration. One complaint describes the failure of the front half shafts on three separate occasions, which they consider a safety hazard. Another owner notes a persistent rattling or grinding sound under medium to heavy acceleration, which Tesla reportedly attributes to normal operation and has not resolved. These issues appear to present at varying times, with no specific mileage range mentioned. The reported symptoms, particularly the half shaft failures, could potentially impact vehicle safety.
STRUCTURE (1 complaints)
STRUCTURE
1 complaintMy 2021 Tesla Model X has a serious safety issue with the driver’s door. When opened, the door swings freely with no support or soft-close resistance and can slam shut or fling wide open unexpectedly. This poses a danger to passengers and nearby people or property. I believe this issue may relate to a latch or hinge mechanism malfunction, and I am concerned about the lack of a safety interlock. I have reported this to Tesla, and they have not acknowledged it as a warranty or safety concern. I am submitting this complaint in the interest of safety for myself and other drivers of this model. I have videos and more detail but this site only allows static photos.
FORWARD COLLISION AVOIDANCE (1 complaints)
FORWARD COLLISION AVOIDANCE
1 complaintSafety-relatedThis complain is regarding the recent recall regarding FSD tesla Smart Summon failures. Incident date June 02, 2024 Car was parked in a parking lot outside a movie theater. I was less than 20 feet away from car with clear visibility, and tried smart summon. Car pulled out of the parking making an acute turn damaging driver side door, and front bumper of car parked next to it. Tesla was contacted immediately regarding this malfunction of smart summon and requested them to stop offering this service to owners as it is dangerous. They took 3 months to conduct an internal investigation but refused to share written results. Instead read a generic statement from their website. Still not received a copy of the investigation. Tesla also refused to take take financial responsibility for the damage and their false claim. Smart Summon is dangerous and Tesla should not be allowed to advertise.
LATCHES/LOCKS/LINKAGES (1 complaints)

How We Calculate Reliability Scores
Auto Reliability Index scores are calculated on a 0–100 scale using a weighted formula that combines multiple public data sources. Each factor is weighted based on its predictive value for real-world ownership experience.
Key Ranking Factors
Complaint Severity
NHTSA owner complaints weighted by component category (e.g., powertrain, safety systems, electronics, cosmetic) — safety-critical issues carry more weight than cosmetic ones. Adjusted for sales volume so high-volume models aren't unfairly penalized.
Repair Costs
Independent reliability ratings based on repair frequency, average repair costs, and severity of typical repairs for each model.
Recall Impact
Number of NHTSA recalls weighted by severity. “Stop driving” and fire-risk recalls are penalized more heavily than minor software or labeling recalls.
Issue Diversity
Measures how many major vehicle systems (engine, transmission, electrical, braking, etc.) have recorded complaints. A vehicle with issues spread across many systems may indicate systemic quality issues.
Scores are grouped into four tiers:
- 80–100: Excellent — Top-tier reliability, minimal issues
- 60–79: Good — Reliable with some minor concerns
- 40–59: Mixed — Notable issues, research before buying
- 0–39: Risky — Significant problems, proceed with caution
Data is sourced from NHTSA recall records, owner complaint filings, and independent repair databases. Scores are recalculated as new data becomes available. While the weighting model is proprietary, all underlying data sources are public and traceable.
