Optima 4-cyl

  • 52,347 miles


We were in my 2011 Kia Optima on a transition ramp from one freeway to another doing about 45 mph. As we rounded a turn we saw 2 cars and a tow truck on the side of the ramp we then hit a puddle (lake) that went across both lanes of this ramp. The water slowed us by maybe 20 mph with water shooting all around us. We then saw a truck coming down a on ramp to merge in front of us he hit another puddle and spun sideways and hit a guard rail. We pulled up next to him to see if he was alright and my car stalled. We could smell gas I thought it was coming from the truck and I wanted to move away from him. The car would not start, I had my 4 year old in the car and he was terrified and crying. Luckily a tow truck pulled up behind us and blocked other cars from hitting us he pushed us out of the lane. When the car was taken to the Kia dealer I found out there is a piece of (plastic or metal I don't know which) that runs down the center under the car, it holds the gas and hydraulic lines up from the front to the back, this piece is held in place with clips ( not bolts or screws ) the water pulled these clips free and my gas and hydraulic lines were pulled down, my gas line broke that was the gas I was smelling, it there had been a spark or flare it could have been fatal. This could also have happened if I was driving in snow. In my opinion this is a factory defect and should be covered under warranty. The dealer said no. So I have to pay $500 plus 5 days of car rental. I'm 59 I have driven every make of car I have never had this happen before.

Kia Optima LX 2011 was purchased brand new at 4 miles in odometer. Problem 1 less than a month: Steering veering to the left an right. Had to steer this car to track straight. The dealer performed minor alignment in October. Car continues to veer left and right. Took car back to the dealer. The tech stated the front end off by 2 degrees and stated he performed the adjustment. The steering problem not fixed. Problem #2: car was parked with fuel reading 42 miles to empty. Returned to start car. Will not crank after numerous attempts. Towed the car to dealer. Car cranked upon de-tow at the location. But still left the car for why it will not crank in the first place. Returned 4 days later. I was advised that the car was empty of gasoline, even when fuel reader clearly indicated 42 miles to empty. Kia paid for rental for 4 days ($100). I was further advised that the fuel regulator was replaced and on back order. The steering problems and the stalling issues are significant public safety concerns since the lanes, arterial roads and highways that I have to drive daily are congested.
