Toyota 4Runner Common Problems

SERVICE BRAKES

Owners of the 2025 Toyota 4Runner frequently report issues with loud brake noises, particularly when reversing. Complaints commonly describe a loud squealing or screeching sound from the brakes, with several owners noting that the issue persists even after service visits. This problem is often reported in vehicles with low mileage, sometimes as early as 400 miles. Some owners express concerns about safety, noting that the noise may lead drivers to subconsciously avoid braking properly, potentially increasing the risk of accidents. Buyers considering this model should be aware of these recurring brake noise issues and the potential impact on driving behavior.

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.

Complaints also mention a clunking noise from the front end and a steering wheel that does not easily return to the center position, requiring constant correction. Some owners note the steering wheel material flaking off, leading to discomfort. These issues are often observed shortly after purchase or around 22,000 miles. Safety implications include potential loss of control, especially in windy conditions or at highway speeds, as some owners describe difficulty maintaining lane position.

These issues present potential safety risks, such as distraction, compromised visibility, and exposure to the elements, which are critical considerations for prospective buyers.

UNKNOWN OR OTHER

Owners of the 2018 Toyota 4Runner report several issues related to glass components, with multiple complaints about spontaneous shattering of the sunroof and other windows, often without any apparent impact, while the vehicle is both stationary and in motion.
