4/5 Overall
NHTSA 5-Star Safety Rating
For the 2018 Toyota 4Runner, steering and brake complaints make up the bulk of what owners report. On the steering side, owners most commonly describe front suspension and steering component failures, including cracked or snapped front coil springs, often noted after cold-weather exposure, leaving vehicles undriveable until parts can be sourced. Brake complaints center on pedal behavior: owners describe the pedal suddenly sinking close to the floor during normal stops, with no warning lights or visible fluid loss, and the problem appearing randomly rather than consistently. A smaller cluster of airbag complaints involves warning lights illuminating, with owners noting the indicator staying on without a clear triggering event. A single report describes a vehicle rolling backward on its own while in park, though that account stands apart from the recurring patterns seen elsewhere in the complaint set.

By System
The 2018 Toyota 4Runner has 5 recalls, the most serious involving steering and suspension fasteners that may not have been properly tightened, which can cause loss of vehicle control or allow a component to detach and become a hazard for other drivers.
A separate fuel system recall covers a fuel pump that can fail while the engine is running, causing a stall without warning. This affects a wide range of Toyota and Lexus models from that era, and the 4Runner is among them. On certain vehicles fitted with an accessory billet grille overlay installed by Southeast Toyota Distributors, a securing nut on the overlay can fracture and allow the grille piece to break free at speed, creating a road hazard for following traffic. Two recalls address load capacity labeling: one involves an incorrect load carrying capacity label that could lead an owner to overload the vehicle without realizing it, and another applies specifically to vehicles modified with a TRD wheel package, where the gross vehicle weight rating on the certification label may be listed incorrectly, again raising the risk of unintentional overloading.
