2011 Toyota Corolla engine problems

Tl* the contact owns a 2011 toyota corolla. The contact stated that while driving 5 MPH, the passenger noticed a burning smell as black smoke began to emit from the hood, followed by flames. The fire department was called and extinguished the fire. The vehicle was towed to the contact's residence. The dealer was notified and stated that while the vehicle was under warranty the fire was not their problem and referred the contact to the manufacturer. The manufacturer was notified and offered no assistance.

I purchased this car as a new vehicle. Ever since I have had it there has always been an acceleration issue to where it does not slow down for several seconds after releasing your foot from the gas. It accelerates often to where you have to apply the brakes firmly to where the anti lock then kicks in. During servicing it has been brought to the attention of the dealership but they have continued to say that there is not an issue.
