On January 24, 2019, my car had to be towed to shakers Kia in watertown ct again. I had been in ct visiting family when I got stuck there due to car issues. I dropped my car off December 7, 2018 for an engine replacement due to a recall and I got it back December 31, 2018. I drove my car home to nc on January 4, 2019 and came back 2 weeks later for my son's surgery scheduled for January 23. On January 22, three weeks after I got my car back, my check engine light came on and my car went into limp mode while driving and had to be towed to shakers Kia. They texted me at 9:08am January 23 with a link to a video saying my car was ready. I picked it up around 5pm after my son's surgery. I didn't have the car 4 hours when it did the same thing again and had to be towed. Shakers told me that I was gonna be responsible for replacing my throttle body because I still have old components from my old engine and my throttle body was part of that. I didn't understand how I have old components if my engine was replaced, so I called Kia headquarters. Shakers replaced my throttle body, no cost to me. Well, when I picked my car up on January 30, I asked about the fuel leak recall and if my car was inspected as Kia told shakers to check mines even though my VIN number wasn't included because my car needed to be checked because my engine was replaced due to the recall. I was told by the technician hector that my car was fine and it didn't need to be inspected because he was very confident in his work. He stated that people were having engine fires because mechanics don't know what they're doing and are installing the engines wrong. My car doesn't run the same after having my engine replaced. It runs and idles rough. I put in numerous calls to Kia about issues with my car and I'm told over and over again that my case manager will call me but it's been weeks and she hasn't called yet.

I've been maintaining the health of my 2012 Kia Optima ex since I purchased in 2014 like clockwork. Last month, I experienced all the dash lights come on while in motion on city roads and I was unable to use the gas pedal. I frantically pulled over and turned the car off then tried to start it, only to be met with a weird sound and a cloud of smoke from the hood. My starter was fried, according to my mechanic. I had it towed to my mechanic and when he changed the starter, the new starter burned again as well as the engine locked up/seized. After finding out a recall (SC147) was active at the time, I called Kia consumer assistance and they replaced the engine issues after confirming that was the problem. Once I picked my car up, I noticed the car was starting up in an odd manner but thought it was due to the engine replacement. About 3-4 days later, my car did the exact same thing as the first time (same smell, sound, and smoke cloud but luckily I was parked at the time). I assumed the starter would be a part of the recall since it broke down the exact same time as the recalled engine, I took the car back to Kia, who told me they wouldn't pay for a new starter even though the engine recall caused it to burn up in the first place and is considered a component of the engine. I contacted Kia consumer again and the case was given to an escalation manager. I had to speak to about 8 different agents and put an email in action to her supervisor to get her to even contact me on this issue. It took her almost a full month to contact and tell me Kia is not responsible for the starter. I'm confused as to why it would not be covered because I've never had an issue with my starter until the engine failed. I am at a loss as to what I need to do to get Kia to see who is really at fault. My mechanic also stated this is the 1st time he's ever seen those 2 parts break simultaneously.

In November 2017 I continuously took my vehicle back and forth to the dealership due to my vehicle not started, and/or needing a jump. Jim marsh Kia had me replace my battery after 6 weeks of complaints and complications. Only for a week later to have me and my kids life at risk, heading South bound on I-15 my car flashed a warning sign stating do not start engine hybrid battery undetected and shut off while a semi truck was behind us. By the grace of god I was going down hill so I swerved to the side of the dessert and road to spare our lives. Just to have Kia tell me 4-5 different excuses as to why my engine failed.

I have a 2012 Kia Optima sx. I brought it in for the engine recall the dealer said it passed no need to fix. A month later I was driving home from work. All of a sudden car gauges went crazy and engine seized. I saw smoke and popped the hood. I than saw a fire ignite inside the engine. By the time the fire department arrived the whole front end of car was burnt up. I see this is an ongoing issue with Kia vehicles starting on fire for no reason.

"takata recall"while driving this car on the highway I notice noise coming from the front. I've had problem with this same thing since 2012, first the string it would pull left and right on its own while drive straight. Kia said they would fix it. There was a recall on this problem, now my rack and pinion is broken, and that's because Kia refuse to fix that problem back in 2012 with the string. Kia sent us a settlement letter, which states they will paid us $531.95 by means of a check, it states it is understood and agreed that this settlement is a compromise of disputed claims and does not constitute, an admission of liability on the part of Kia. We did not sing that letter because Kia cars are no good! and there has been recalls since that letter was sent. They tried to black mail us we didn't fall for the scam. The company know this car is no good. If you need that letter sent to you I can do that to. Someone could die because of this problem its dangerous, I work in the mountains this problem needs fixing now not later now!!!. sincerely, need this problem fix

On December 10th, 2018, my daughter was driving the Kia Optima 2012 from san antonio to houston on I-10 E. at 4:15 pm cst, the engine light and multiple other lights suddenly came on in the display and the car slowed to a stop before exit 591 (schertz). She was able to pull it to the right-side curb of the highway while the car was slowing and it stopped completely. She tried restarting the car a few times, it would not start, and she quickly noticed smoke coming from the front hood so she immediately exited the vehicle. She then called 911 as the smoke got worse and a few nearby drivers helped her quickly get as much of her stuff from the car as possible. Then they all moved across to a safe place and within 10 minutes the car had caught on fire (by 4:25 pm). See pictures attached. The police arrived and blocked the highway and after a while the fire truck arrived. It took some time to put out the fire as they were waiting until the half tank of gas completely burned. I had a few recall letters from Kia, so I had taken the car on November 30th to the dealership in conroe (cowboy Kia) and they took care of all the recalls ' a total of 3 items including the acu wiring extension installation. The dealer also did a multi-point free inspection and reported everything was in good condition. The car had around 54,000 miles. I also had an oil change recently on September 15th, 2018.

On December 9, 2018, I attended my son's soccer tournament on a cold Sunday afternoon (approx. 30 degrees). During half-time I decided to sit in my 2012 Kia Optima to warm up. After 10 minutes or so, I smelled something burning like the smell of a burning engine. I then noticed greyish blackish smoke coming out from the hood of the vehicle which quickly turned into flames. I immediately shut my car off and barely exited the vehicle in time. The entire bottom of the driver's door, driver's front wheel and hood was on fire. Within a matter of minutes, my entire vehicle was engulfed in flames. It should be noted that I got a brand new engine (so they say) installed by Kia just 8 months ago due to the recall. The car had been making a horrible noise so I took it to Kia and they informed me that my engine was bad and part of a recall. They ordered the engine and had it installed in a matter of days. Once again this was just 8 months ago!! I am currently working with my insurance company and the local fire department to determine the cause of the blaze however, due to the severity of the damages, we may never know what the true cause of the fire was is what was told to me. Kia needs to give me and the hundreds of others who have experience this type of trauma some answers as to why this is happening and how they plan to rectify this situation! this should not have happened. I should have been able to sit in my car in 30 degree temperatures for hours if I wanted without it going into flames. I am pleading with the federal government to investigate immediately.
