Car was serviced by dealer for four years. I purchase the car, have the coolant water flow tank pressured tested and three weeks later leak or crack in the coolant water flow tank. All liquids leaked out, engine over heated and blew. Had to replace the engine. Over 6000. To repair.

I have a 2004 magentis which I heard is like the serento. The timing belt jumped and this took out the motor. Up to this I loved my car. Kia said there was nothing they could do but replace the engine at my cost and I would not get it back until it was paid for. Well being a single mother of 4, still making payments on the car for another 4 more years. Needless to say I have a car with no motor and making payments.

2004 Kia Sorento leak in A/C coolant bottle. My car was in for a pressure test three weeks before this and it past just fine without any leaks or cracks. On the freeway, over heats, pull over, all the fluid leaks out, engine is dead and must be replaced. Just hit 61,000 miles. Kia does not offer 100,000 mile coverage unless you are the original owner. I am the second owner and have had the car three months. $5000. Later I have my car back. Kia will not honor to do the work because they say it was a long term leak. Well, before I purchased the car, Kia did all the maintenance on this car for four years..... if it was a long term leak, shouldn't they have caught it" they say no. I also purchased an extended 80,000/3 year warranty when I purchased the car, they also declined my car coverage because they cover nothing due to any overheating. This is really just a complete joke. I did nothing wrong. Kia serviced the car for four years. I had the car in three weeks before it blew up and it was tested and filled with fluids. Why does this not make any sense??"

Sorento 6-cyl

  • Automatic transmission
  • 60,537 miles
The contact owns a 2004 Kia Sorento. While driving 20 mph, the vehicle began to sputter and hesitate and then it completely shut off. The contact restarted the vehicle and drove to the dealer. The dealer stated that the coolant compartment had a leak and was dripping coolant into the engine compartment, which caused it to hesitate. She called the Kia corporate office and was informed that her vehicle was out of warranty and the repair would not be free. The current and failure mileages were 60,537.

  • Automatic transmission
  • 60,000 miles
After already replacing a crankshaft and a speed sensor in my 2004 Kia Sorento ex, I am now experiencing a knocking sound under the hood. It usually starts while waiting for a stop light but also while driving down the road. My warranty is out and I can't afford to have it worked on at this point. Don't ever buy a used Kia Sorento without checking carfax first!!!!
