Overview of 2012 Kia Sorento engine problems

The main issue that plagues the sorento and causes the 2012 Kia Sorento engine problems is the catastrophic engine failure

  • Catastrophic engine failure results in a complete engine rebuild or replacement, causing owners to pay an extraordinarily high repair cost to fix this issue. 
    • If the problems are not remedied, the driver will have a much higher crash risk.

 

The engine in your car can fail for several reasons, any of which can cause the 2012 Kia Sorento engine problems. The most common causes of engine failure include a lack of maintenance, engine oil leaks, and over-revving by the driver that can put excess stress and strain on the engine. 

  • If you do not stay up to date with the maintenance and oil changes, sludge can accumulate and breakdown the internal engine components. 
  • Sludge accumulation and debris building on the interior of your engine can increase friction, causing heat to build up and raise the internal temperature. A higher temperature will damage other internal engine components, leading to further 2012 Kia Sorento engine problems. 
  • In addition, if a car is continuously pushed over the maximum and recommended RPM, dynamic engine components will break down, causing premature engine failure and causing the extensive 2012 Kia Sorento engine problems.
  • Even if you keep up to date with the maintenance of your car, most vehicles will experience significant issues with their major components at some point in their lives. 
    • These important components include the engine, transmission, or the body of the car itself, with car owners having to perform an expensive repair or  replacement oftentimes below the 200,000 mile mark.

  • Owner #1 reported the car stalls several times per week while driving, even after replacing the electric module, crankshaft sensor, alternator, throttle body, CA< sensor, and the MAP sensor. 
  • Owner #2 stated that the car completely seized and failed within a few months of purchasing. Smoke came out of the dipstick hole and the oil looked filled with sludge, too hot, and debris-filled. 
  • Owner #3 reported the car suddenly lost power and the power steering suddenly stopped working while they were driving at highway speeds. Along with the loud cracking noises, the car had to pull over to the side of the road. The owner complained the Kia sorento was not involved with the aforementioned recall.

  • Owners of the sorento may have to replace their piston rings, costing around $1,500 minimum for this task. The reason this fix is so costly is due to the complete disassembly of the engine to replace the piston rings and recondition the cylinders.
