Problems with 2004 Kia Sorento SERVICE BRAKES, HYDRAULIC

We purchased our sorento used (approx 65k miles)about 3 years ago. since then, we've had to replace the gas tank ($1500) among other things. this year has been absurd: had to replace the radiator, water pump, computer system (2 months, $4700), brakes ($750) and 2 batteries. 2-3 months ago, we noticed a clunking/chunking sound that grew steadily worse. it sounded as if the 4wd was engaging and disengaging every 3 seconds and felt very unsafe at high speeds. i took it to kia of cobb county and was just given a quote friday for a new transfer case, drive shaft, "rear end chunk" (all the service rep could tell me) and 4 new tires. quote for this work ($9767). the transfer case alone was around $5700. this vehicle now has 112k miles and is less than 10 years old. the blue book value is (was) around $5-6000 and we're told it'll take $10,000 to fix it? i called kia's corporate office to ask if this was to be expected at kia. i was told that our vehicle was not under warranty. i said, " i'm just asking if there's anyone at kia headquarters who believes in their product and wants to protect the kia name and you just keep apologizing." the rep responded, "i'm sorry, sir." we've found multiple complaints online from kia owners reporting similar issues (chunking, transfer case, etc). when does this become.a recall issue? a safety issue? *tr

Rotors warped. i experience shuttering when stopping at any speed. i plan to take into the shop this week for repairs. my friend with a jeep cherokee had the exact same problem and jeep issued a recall. looking at the number of complaints i've found on this for kia sorento, i feel kia should take the same action. *tr

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. *jb

Tl*the contact owns a 2004 kia sorento. the vehicle vibrates when the brake is depressed at 40 mph. the front rotors were warped and later resurfaced at 18,000 miles. the vibration duplicated approximately 6,000 miles after the resurfacing. the dealer replaced the front rotors, however the vibration recurred approximately 29,000 miles later. the dealer replaced the front rotors for the second time. presently, the vehicle is beginning to vibrate again. the vehicle has not been back to the dealer for inspection. the current and failure mileage were 33,700 miles.
