“Last week, on aug 29th 2020, I tried to make a left u-turn on a residential street and the steering wheel locked up. I got scared and just drove forward to the next street and turned right onto that street. On aug the 17th, 2020 I had my car inspected. The mechanic said the brake fluid was leaking and had to fix that. Approx 2 weeks later, sept 2nd, the motor blew on my car while driving on a hwy. There was black smoke coming through the A/C vent right before it happened. The car is a total loss.”

“After returning from work and parking my vehicle at home, the car sat in my driveway in 40 degree weather for approximately 12 hrs. I woke up the next morning and found my car on fire and is a total loss. The police and fire department were called and dispatched to my home. The fire department extinguished the fire and determined it was probably an electrical fire. There is no remote starter installed or any other accessories installed in the vehicle after purchase. …”

Now recently last three month happening exactly like following post. I have contacted dealer and have appointment this week. (see what happens..) =========================== late last year (2014) in our Kia Optima 2009 got some transmission issue which is difficult to explain for.

“My 2012 Kia Optima was found to have a leaking oil line which feeds lubrication oil from the engine to the turbocharger. This occurred at 58,000 miles, well within the 100,000 mile warranty for the drive train. However, the dealer informed me that the oil supply line was not covered by the warranty, but the engine and turbo were. The loss of this line would result in the failure of the engine due to no oil, as well as the turbo, and this was most likely to fail when under acceleration in traffic as that is when the load on these components is greatest. …”
