Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Crankshaft bolt backed out lost power steering brakes, Kia is aware of this problem from 2002 to 2009 many reports have been filed, its the manufacturing of the bolt which is to small, they are not standing by this defect, there is no permenant fix for this and Kia isn't warning anyone of this problem which could lead into a fatile accident with injuries and death.going at a high rate of speed there would be no control even at slow there is no easy turning the im stuck with this problem and a temp fix wont fix it, so now I have no vehicle or anyway to get one, no way to work, no money to temp fix it, this is unjust and this vehicle should have never passed specs to be on the road.Kia should step up and honor there products, they are deceiving buyers and putting there life in danger and U don't know it till it happens, I didn't...I was taking my daughter to school I am thankful I wasn't on the highway possible resulting in my familys life or someone else on the road, with no control all because of there negligence not caring for peoples lifes but for money, its sad.if U pull up crankshaft bolt for Kia it will show you all the complaints and problems and this is a manufacturing problem and a dangerous defect, because you lose control of handiling of your vehicle.

The contact owns a 2003 Kia Sorento. While exiting the driveway with the brakes engaged, the brakes failed to stop the vehicle. The vehicle was taken to an independent mechanic who stated that there was excessive corrosion that fractured the subframe and damaged the brake lines. As a result, the brake lines needed to be replaced and the center section of the frame needed to be cut and replaced. The subframe was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 31,000.

While the car was in for an oil change the tech noticed a couple of brake lines looked wet, when they where checking the lines they noticed the rear sub-frame which the lines were connected too was totally rusted out. The car is no longer drivable due to the fact that this sub-frame holds the rear differential in place.

The contact owns a 2003 Kia Sorento. The contact stated that while driving approximately 55 mph, the vehicle made an abnormal noise when the battery and another unknown warning light illuminated. In addition, the contact had to pump the brake pedal several times before the vehicle would stop and the power steering stop working. The vehicle was taken to an independent mechanic. The technician diagnosed that the crank shaft pulley bolt was holding too much weight causing it to fracture. The vehicle had been repaired but the failure recurred on numerous occasions. The manufacturer was notified of the issue. The approximate failure mileage was 36,000.

As I was leaving work, the crankshaft bolt broke, and the bottom/pulley came out and hit the road.thank god I was still in the parking lot. I had it towed to a automotive shop to have it fixed it, has $ $768.45 plus 75.00dollars to tow it. I got my 2003-Sorento back on 06/20/2013 on 07/06/2013 I was going down the hwy about 55mph. And the crankshaft/bolt broke again after only having driven 1,674miles. I am a single mom of two, living week to week and I can, T afford to fix it again and it is our only car. If Kia is not going to fix the crank/shaft bolt ( it is a dealer item only) and they keep breaking, just look at all the repute incidents, over and over, then they need to be made to do a recall, I would like to know if their is a class action law suit on this matter.

Driving car down road when brakes went soft pulling into my driveway was able to stop before brakes went out fully. My son was practicing for his road test. Car also has control issue does not feel very stable. Feels like it want to tip over. Noise in front end dealer said you will get used to it. When it gets bad enough they may be able to find it. Biggest piece of junk I have ever owned. Would never buy another Kia.

Power brake system failed when attempting to brake while going 15 mph. Took vehicle to service center. They reported that the brake lines had rusted through causing total loss of brake fluid and brake system functionality. Once the brake line was perforated it completely rendered all but the emergency brake inoperable. Luckily I was able to stop using the emergency brake because of the low rate of speed. Had this occurred at a higher rate of speed (e.g. 65 mph) it could have been disastrous. All brake lines had to be replaced at a cost of $670. I've owned many vehicles in my lifetime with similar age and mileage, but have never had brake lines rust through. I live in a northern climate (NY state), but this should not happen. Friends of ours bought their 2003 Kia Sorento one week after we did. Their vehicle suffered the exact same brake line rust through as we did las year, with only 40,000 miles on the vehicle, so I'm interested in knowing what percentage of same make/model vehicle has experienced the same failure.

The contact owns a 2003 Kia Sorento. The contact stated that while exiting a parking lot at 10 mph, the brakes were depressed and felt spongy. The vehicle failed to respond and the contact had to utilize the parking brake to stop the vehicle. The vehicle was taken to a local mechanic who advised the contact that the brake lines were rusted and fractured, causing the loss of brake pressure. The vehicle was repaired. The manufacturer was not notified of the failure. The failure mileage was 84,000.
