Car started making a squeaking rubber noise in afternoon then by next early morning car was making a loud squealing noise then a loud thunk and by the time we got it to the Kia dealership it was slightly shaking. Was told the whole drive shaft needed to be replaced and it would take 6 days to get the part in! no loaner car available so I'm left with no transportation to and from work!! thank god this is warranty work otherwise I'd be screwed even more!

I have 3 major failures w/my new Kia Sorento '04 since buying it in Dec '03 from peak Kia in colo.the 1st failure, the anti lock brake control unit was replaced in Dec '03.the brakes engaged when they shouldn't. I have complained many times about a road vibration at 68-72 mph. Dealer has seen my car 5 times for this problem. The 1st time the dealer said they couldn't find anything wrong, but said they had only driven it to 63 mph. The 2nd time I took it in, problem had been noted in a number of Sorento's nationwide & they were going to need to change the drive shaft. 3rd time for this same problem & upon picking up the car found out that they didn't change the drive shaft, but greased it w/special heavy duty grease &turned it 180 degrees. I asked why hadn't changed drive shaft, & they said the manufacturer's technical service bulletin recommended this procedure 1st. The vibration has slowly returned. I called the dealer & they said they would put me on list to drive car w/regional service mgr. They called & said he was in town, so I went to drive car with local service mgr & regional service mgr.they felt there was nothing highly noticeable about vibration & said it could be the roads. They told me to call back if it got worse. In August '04, were driving & my car began to smoke. A huge trail of smoke coming out from under car. We pulled to the side of the road & called 24hr towing from the dealer. Car towed to osborn Kia in colo. & found that the entire rack & pinon steering mechanism & gear box had blown up throwing steering fluid on the engine. So much smoke I thought the car was on fire! what could have happened if our steering would have gone out in a tight turn! the dealer's service mgr said in all of his year's the dealership had never replaced this part. The entire steering system replaced, the car is now vibrating once again at 68-71mph. I am going to contact the dealer but am concerned they will not do anything to fix this.

Since purchasing new 2004 Sorento in February 2004, have had the vehicle to two different dealers for five attempts to resolve a vibration from unidentified source. The vibration was first experienced at 70 mph. One dealer has replaced the gear cluster in the rear differential, balance and rebalanced tires, replaced rear U-joints, and replaced front drive shaft. This did not correct problem. Second dealer replaced rear drive shaft a second time. Vibration is now worse. It can be felt at 50 mph and 70 mph. Have met with Kia factory rep. Kia states they have a technical bulletin on this problem.
