2020 Toyota 4Runner VIN Check, Recalls & Reliability

UNKNOWN OR OTHER

Owners report two primary issues with the 2020 Toyota 4Runner in the unknown or other category. Firstly, multiple complaints describe the sunroof shattering unexpectedly while driving, with references to a loud bang similar to a gunshot, and glass raining into the cabin, posing a potential safety risk due to driver distraction or injury from glass shards. Secondly, one complaint highlights a problematic SOS system, which fails to connect reliably and reportedly causes battery drain. Additionally, a single report mentions an exhaust or sulfur-like smell inside the cabin when driving at high speeds with the air recirculation on. These issues are noted without specific mileage data, though one sunroof incident occurred approximately thirteen months post-purchase.

AIR BAGS

Owners of the 2020 Toyota 4Runner frequently report issues with airbag deployment failures during crashes, with four out of five complaints involving accidents and two mentioning injuries. Common symptoms include airbags not deploying upon impact, even in significant collisions, and a lack of warning lights indicating system malfunctions. One complaint highlights a design feature where the front passenger airbag deactivates for passengers weighing less than 100 lbs, impacting safety for lighter adults. The reported incidents occur at mileages ranging from approximately 13,000 to 19,000 miles, suggesting potential reliability concerns within this mileage range. These issues present significant safety implications, particularly in crash scenarios where airbag deployment is critical.

Severity signals: 4 crash, 0 fire, 4 injury reports

STEERING

Owners report issues with the steering of the 2020 Toyota 4Runner, particularly involving noticeable shaking of the steering wheel at highway speeds, typically between 58-68 mph. This shaking is described as severe, with one owner noting it causes the steering wheel to move as much as 1.5 inches back and forth, and persists despite multiple attempts to balance and align the tires. Some complaints indicate that this issue is recognized by Toyota as a characteristic of the vehicle, attributed to "harmonics." The shaking begins early in the vehicle's life, with one owner experiencing it in the second week of ownership. Safety implications are noted, as the shaking could potentially affect vehicle control, especially in adverse conditions. Additionally, one complaint mentions a separate issue with electronic power steering requiring increased effort to maneuver, linked to a fluid leak from the front timing cover at 88,000 miles.

SERVICE BRAKES

Owners report two primary issues related to the service brakes of the 2020 Toyota 4Runner. Several complaints describe a brake pedal that goes to the floor, causing a temporary loss of braking ability, which can be remedied by pumping the pedal; this issue is noted to occur intermittently, particularly after the vehicle sits overnight or during slow stops. Another reported issue involves a loud squeal from the brakes in cold conditions, which has not been officially addressed by dealerships. Additionally, a few owners mention a hissing sound when applying the brakes, accompanied by an electronic noise. These symptoms do not seem linked to specific mileage or timelines but do suggest potential safety implications due to the temporary loss of braking function.

SUSPENSION

Owners of the 2020 Toyota 4Runner report issues with the suspension, particularly with the X-REAS system in the Limited Edition, which some describe as failing around 45,000 miles. This failure is noted to cause instability and potential loss of vehicle control. Another reported issue involves a fractured front coil spring discovered during a routine inspection at approximately 53,000 miles, leading to a necessary repair. These complaints highlight potential safety implications, such as loss of control, which may concern used car buyers considering this model.
