Check Engine Light On problems of the 2007 Toyota Avalon

When driving north on I-95, my car began to slow down even though I had not released pressure on the gas peddle, so I accelerated. As soon as I accelerated, the car then began to run extremely rough, the rpm monitor fluctuated back and forth, and the began to slow down even more. I looked in the rear view mirror to check traffic as I prepared to pull off the interstate and saw smoke coming from the rear of the car. When I stopped and exited the car, smoke was then bellowing profusely from the front right side of the hood and upper right tire rim, so much so that I thought the engine was about to explode. It should also be noted that the check engine light never came on. A tow truck was called and now I'm waiting for my local Toyota dealership to open so that I can find out what is wrong with my car. A similar energy surge and rough driving occurred approximately one year ago and my car was towed in, but no problem could be detected. The problem stopped as mysteriously as it appeared, with no serious reoccurrences until yesterday, 9/7/15. In 2014, the mechanic chalked the problem up to possibly bad or cheap gas.

Steering colum adjusting control continues to release. This causes the steering wheel to go into the the dash area or up or down. There is no control of steering. Before this incident, oil burst all over the engine and drained out of my car, spilled onto the floor of my garage. The oil light or check engine light never came on. Dealer made repairs after keeping my car -not a recall notice but a noted problem. No power while pressing on the gas. There is a delayed reaction resulting in slow or no speed for passing or just driving (dealer indicated power trans problem - not recall kept car 3+ days for repairs). The grey paint has spots ithat will not come out with a wash and wax.
