On 5/11/2025, my husband and I were returning home from the grocery store. I was operating the vehicle at the time of the incident. Upon arriving at our residence, I pulled into our driveway, which has a slight downward incline. As in our usual practice, I attempted to stop in front of the garage to unload groceries before entering, as the hatch of our vehicle can come in contact with the garage door when opened inside. While aligning the vehicle with the garage door, I began breaking and turning slightly to the left. However, as I attempted to come to a complete stop in front of the closed garage door, the vehicle unexpectedly accelerated forward. Despite applying the brakes, the vehicle continued moving and crashed through the closed garage door. Due to the steering wheel being slightly turned, the vehicle veered left upon entering the garage, striking the left interior wall and a 32 foot ladder that was leaning against it. The impact with the wall and ladder brought the vehicle to a stop although the engine continued to rev and the vehicle attempted to move forward. My husband instructed me to shut off the engine, which I did immediately. My husband was not injured in the incident. I sustained pain in my left shoulder and upper left back. A medical evaluation indicated that the pain is expected to subside within a few weeks; imaging will be conducted if symptoms persist. I have filed both auto and homeowner's insurance claims regarding the incident. Additionally, I contacted the dealership, which advised me to report the issue to the manufacturers corporate office. They noted that the vehicle is equipped with a fail-safe system designed to prevent simultaneous engagement of the brake and accelerator. This was a very scary incident that I don't want to have happen to someone else.

This vehicle has experienced the front coil spring cracking on the right front, the left front cracked at 114K miles. This is a very common issue with 2015-2017 Toyota 4Runner TRD-Pro, it is a design defect in the way the coil spring terminates and sits on the top hat and bottom spring perch. Toyota has discontinued the defective parts and redesigned the spring perch on the updated strut and uses a different spring, but it is not recalled and should be as this is a safety defect. A broken coil spring can cause sudden loss of control of the vehicle resulting in a crash and even death.

I drive for a living and yesterday I was driving while this happened 3 separate times. I was going 70 mph on the highway when my radio, usb ports blower motor and dash cluster power went out.

My Date , sitting in the passenger seat says Her seat is get warm , then says , it's getting really hot ! I looked at the seat warmer switch and noticed and said , weird , the switch isn't even on .
