The cause is UNKNOWN. The selling dealership evaluated the vehicle and performed a front-wheel alignment, but the shuddering persists.

While traveling home to Louisiana from a vacation, I noticed the engine temperature what stuck on Cold. We also were experiencing loss of power steering, and loss of AC in the car. We stopped at AutoZone in Destin, FL where they completed their FixFinder which reported the thermostat needed to be replaced, being it was stuck in the open position and wasn't properly gauging the engine temperature.

My vehicle has shown the service stabilitrak, tcs off, and transmission unable to shift soon while driving. This happens several times; and after certain times the car will not shift and I am not able to go past 50-60 mph.

As I was driving I smelled a burning smell. A few seconds later saw a fire/smoke coming from the front right side of my car. I pulled over and took a look. Confirmed my car was on fire. I called 911 who connected me to the fire department. I then ran to the gas station and got a fire extinguisher. I then used the fire extinguisher and extinguished the fire. I made a claim with my insurance company who ordered a tow truck to transport the vehicle to an auto repair shop.
