Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“The car has the iforce max powertrain. At low speeds or in stop and go traffic, when the car has come to a stop, the car will lurch forward, which could potentially cause an accident.

This is a huge safety issue if the car pushes itself forward and potentially causing an accident. The transmission system is very unrefined.”

“At approximately 520 miles, while performing a low speed left hand turn, the vehicle experienced a sudden mechanical thunk in the drivetrain followed by an immediate loss of motive power (Limp Mode) in my new 2026 Toyota 4Runner TRD Pro.

A diagnostic health check at an authorized dealer confirmed stored DTC fault codes P281671 and P08BA71, indicating that Pressure Control Solenoids Actuators H and L were in a stuck state. …”
