2021 Toyota 4Runner VIN Check, Recalls & Reliability

STEERING

Owners of the 2021 Toyota 4Runner frequently report issues with steering wheel shake and vibrations, particularly noticeable at highway speeds between 50-70 MPH. Symptoms often include a feeling of instability or loss of control, with some owners describing the vehicle pulling to the right. Many complaints arise shortly after purchase, with some mentioning the problem within the first 100 to 500 miles. Despite multiple attempts at tire balancing, alignments, and even replacing tires, the issue persists for many. Safety implications are highlighted by several owners who fear losing control, especially in adverse weather conditions. This information is particularly relevant for potential buyers considering a used 2021 4Runner.

ELECTRICAL SYSTEM

Owners of the 2021 Toyota 4Runner report multiple issues related to the electrical system, with a focus on door lock actuator failures and an airbag system malfunction. Complaints frequently mention door locks failing on various doors, including the front passenger, front driver, and liftgate, over a span of several months, which affects the ability to enter or exit the vehicle safely. Another owner describes a malfunction in the SRS airbag system, specifically the front passenger Occupant ECU, which was diagnosed at a dealership and resulted in a costly repair. Additionally, one owner reports a significant safety incident where the vehicle caught fire while parked in a garage, leading to a total loss of the vehicle and damage to property, although the exact cause remains undetermined. These issues are reported at varying mileage ranges, with the fire incident occurring at 5,500 miles, highlighting potential safety implications for prospective buyers.

SUSPENSION

Owners report issues with the suspension of the 2021 Toyota 4Runner, particularly with the TRD Pro model's FOX shocks, which produce a clunking sound at low speeds. This problem persists despite multiple shock replacements under warranty. Another common issue involves a steering wheel shimmy occurring intermittently at speeds between 55-63 mph, which is noted in owner forums but lacks a definitive solution. Additionally, some owners mention delays in recall repairs due to unavailable parts, although no failures or safety incidents are reported. These complaints suggest potential concerns for buyers, especially those considering models with specific suspension features or those affected by recall notices.

BACK OVER PREVENTION

Owners report issues with the 2021 Toyota 4Runner's backup camera, noting it fails to function consistently. Complaints frequently mention the camera displaying a black screen instead of showing objects behind the vehicle. Symptoms typically emerge without any dashboard warnings or error messages. One owner reports a crash resulting from reliance on the backup camera, which did not activate, leading to a collision with a parked car. These issues have been noted to start occurring approximately 6-8 months prior to the complaint, with no specific mileage mentioned. Buyers should be aware of these potential safety implications when considering this model.

Severity signals: 1 crash, 0 fire, 0 injury reports

VISIBILITY/WIPER

Owners of the 2021 Toyota 4Runner report issues with the vehicle's visibility systems, particularly the sunroof and sensors. One owner describes the sunroof glass shattering unexpectedly while driving, which resulted in glass falling onto the sunroof shade, highlighting a potential safety risk if the shade had been open. Another owner reports failures in the pre-collision system and headlight high beams during snowy conditions, noting that ice buildup on the forward sensor and headlight cover rendered these systems ineffective. These incidents occur at low mileage, with one report mentioning the issue at under 500 miles, indicating potential concerns for new or low-mileage vehicles. Safety implications include reduced visibility and compromised safety systems in adverse weather conditions.
