2014 Ford Explorer cruise control problems

Tl* the contact owned a 2014 ford explorer. While reversing at approximately 10 MPH on an incline, the brake pedal was depressed and failed to respond without warning. As a result, the vehicle accelerated and the contact crashed into a tree. The contact sustained a fractured back and hand injury that required medical attention. A police report was filed. The vehicle was towed to an independent mechanic, but was not diagnosed or repaired. The vehicle was destroyed. The manufacturer was notified of the failure.

Every time the SUV is accelerating over 3.4k rpms for a duration of greater than 3-5 seconds, the AC system fills the cabin with nauseating gas. The smell has changed over the course of ownership from burnt hair smell, now to a exhaust, rotten egg/carbon smell. Occurs with AC system off, or on independent of fresh air or recirculate mode. Smell lingers for minutes afterwards. Taken to dealer but unable to replicate problem. Also, they said that the TSB for the issue did not apply to 2014 models.
