    after hearing a loud screaching noise from my engine that sounded like the fan belt, I called the dealer & told him I was on my way in but the car stalled on the way. Turns out my crank shaft pulley bolt broke off and the dealer said it damaged the crank shaft sensor and the timing belt which I just replaced a few months back.
    I'm picking the car up today and he said I can expect to pay around $2100!!!! I am learning that this is a common problem with the Kia's and that their warranty won't cover it. I think Kia needs to step up to the plate and cover the damages caused by their defective bolts.

    Crankshaft bolt sheered off inside the engnine block. Despite being recalled part, kia will not do anything positive to resolve. My nice SUV is not worth only what I can donate it for. New engine will cost more than car is worth. When contacting customer service, nothing was done to help. Dealer was no help either, told me part was not recall. Angry is a good word but doesn't quite cover it. Over the years I have read many negative reviews of Kia's products and should have unloaded mine before it completely died. I will never buy a kia again and I encourage others not to either. They do not stand by their product and customer service is laughable.

    Several months back I was driving when my check engine, battery, and brake lights went on and power steering went out. I made it the 3-4 miles back home, pulling soley on the power of my battery. When I looked under the hood, none of my belts or pulleys were moving, but the crankshaft bolt was spinning. When I took my car in, I discovered that the bolt had broken, some sprocket had sheared off and was pushed up into my engine block. All this was found only after they determined I needed a new battery and, of course all new belts, and I pushed this issue as to the bolt, which, somehow they didn't see immediately. Only to then find out that this was not covered under warranty and would cost me $1200. Within 3 weeks, my check engine light came on and all of the same things happened added on to that was the engine stalling in the middle of traffic. Again I took the car to the dealer, thinking it had to be the same problem AGAIN. No, this time it was the Crankshaft sensor and, "hey you should replace the CAM sensor too, as well as all new spark plugs and wires." Again another $1200. Again 2 weeks later, the check engine light and and same problem along with a knocking in the engine like I threw a golfball in a dryer. Hydrolic Tensioner went out...another $600. Now, SAME problem, again I looked at the belts and pulleys, nothing moving, and althought the bolt seems straight, the pulley is twisted out. KIA, this is a HUGE problem. Either your Sorentos have issues or your mechanics stink! My suspicion is that both apply.

    The crankshaft bolt broke off and had in shop for a day as they said nothing was wrong after telling them I heard a thumping noise when engine shut off. I go to drive off lot turning on AC as the belts start squealing loud so get home a couple mins later to look under hood and see the belt slipping off tension pulley and then look to the crankshaft and see it is not on straight. When I look down see this grey bolt sitting on skid plate yeah you guessed correctly it was the crankshaft bolt. Really how could dealership miss this....Pissed so went back in they towed vehicle to shop and said they would take care of and make it right. Yeah Kia should issue another recall as it looks like it's not the bolt check this youtube video out.

    I bought a used 2004 kia sorento in august of 06. By march of 08 I had already had several problems with the vehicle including my crank shaft bolt breaking in half. My car was under warrant and they wouldn't replace it saying my oil wasnt changed. Repair cost for this is close to 9,000.00. I paid them 900.00 to shove a new bolt in there but two weeks ago it felt out. I advise anyone with this problem should report to the nhtsa and any where else and maybe one day we can get thisproblem taken care of

    We bought a used 2004 Kia Sorento in july of 2010. 10 months later, we lost the power steering and alternator while driving and had to fix the crank pulley. A few months later, we started to hear the belt noises again and had it checked to find out we had the same problem re-occuring; 9 months after the first repair, we had to change the crankshaft pulley once more. This time we went to the dealer to make the repairs and he told us that he cant garantee the job, since this was a problem that should re-occur. The second time we had to change the timing belt (was reasonnably used) but the mechanic showed us that the gears were not in the correct place, the second gear was off by a whole dent.

    I bought the vehicle used and less than a month later the crankshaft bolt came loose and i lost steering A/C and the Alternator was'nt charging. when i made it home the crankshaft pulley was loose and the belts were off.about 2 months later it did the same thing.The problem with this it that it usually shears the pin on the end of the crankshaft what helps hold the pulley on.Sorry Design By Kia!!

    crank shaft bolt backed out locked up the belts, still trying to get bolt out. This should be on kia knowing that all of these problems are coming from piss poor design but of course they wont step up and admit that there at fault with putting cheap parts in there vehicles. sad
