AIR BAGS
Owners of the 2021 Lexus RX frequently report issues related to airbag recall repairs being unavailable for extended periods, often exceeding two years. Common symptoms described include the airbag warning light illuminating, especially when objects are placed on the passenger seat, and concerns over the passenger side airbag potentially not deploying due to weight calculation errors. Complaints often mention that parts for the recall repair are not expected to be available until 2025 or 2026, with some owners experiencing these issues as early as 76,000 miles. Safety implications include reports of two crashes and two injuries, although specific details on these events are limited. Potential buyers should be aware of the ongoing recall and the extended timeline for parts availability when considering a used 2021 Lexus RX.
Owners of the 2021 Lexus RX report several structural issues, with a focus on malfunctioning doors and drainage problems. Complaints frequently mention driver and hatch doors unexpectedly opening or failing to operate correctly, with one instance leading to a crash when the driver side door opened while driving. Additionally, there are reports of the rear hatch door not responding to the key fob or manual buttons, resulting in difficulties with loading and unloading. Another issue involves water leakage through the sunroof drain system, leading to water entering the passenger compartment. Safety implications are evident in the door malfunction that led to a crash, and buyers should be aware of these potential issues when considering a used 2021 Lexus RX.
Owners of the 2021 Lexus RX report issues with seat belt functionality, particularly during collisions. Common failure patterns include seat belts not engaging properly, as seen in incidents where seat belts failed to restrain occupants, resulting in injuries such as compression fractures and bruising. Complaints frequently mention seat belts either not locking or remaining extended, with no prior warning lights or messages indicating a problem. These issues are reported across various mileage ranges, with one specific report at 58,000 miles. Safety implications are significant, with multiple reports of crashes and injuries, highlighting potential risks for buyers considering this model.
Owners of the 2021 Lexus RX report issues primarily related to the HVAC system and electrical components. Complaints frequently mention HVAC condensate drain failures leading to water intrusion and mold growth in the cabin, particularly around 19,000 miles, causing health concerns and potential electrical damage. Additionally, some owners describe sudden transmission issues and vehicle control problems, attributed to an oily residue on the spiral cable, with symptoms appearing around 12,728 miles. These issues may pose safety risks, including loss of vehicle control and compromised air quality, which are important considerations for potential buyers of this model.
Owner complaints3
UNKNOWN OR OTHER
Owners of the 2021 Lexus RX report issues related to the vehicle's parking system and structural integrity. One complaint describes a parking system failure where the vehicle rolled unexpectedly after being placed in park, resulting in a driver injury.

These reports do not specify mileage but involve significant safety implications, particularly regarding the parking system and moon roof integrity.
Owners of the 2021 Lexus RX report issues related to the performance of Bridgestone Ecopia tires, particularly in adverse weather conditions. Commonly noted symptoms include tire delamination leading to rapid deflation and poor traction on snow and ice, which in one instance resulted in a crash at low speeds.
