The contact owned a 2012 Kia Optima. While driving 45 mph off of the interstate, the vehicle stalled without warning. The contact was able to pull the vehicle over into a parking lot. The vehicle was not able to restart. The contact left the vehicle overnight and had it towed to midas (6500 SE 14th St, des moines Iowa, 50320) the following day where it was diagnosed that the engine failed and needed to be replaced. Due to the $7,000 repair cost, the contact decided to sell the vehicle due to the value of the vehicle per the mileage and condition. The manufacturer was contacted in July of 2017 after finding out a month earlier that the vehicle was included in NHTSA campaign number: 17V224000 (engine), after the vehicle had already been sold. The failure mileage was 124,890. Parts distribution disconnect.

My car has been at the Kia dealership here in key West, fl due to the engine seizing just like the recall states. It has been there for 2 weeks and still no word from Kia if they are gonna fix it. I have been without a car for that period and am being told there is no timetable on this as well. So after two weeks I don't even know if it will be fixed or anything. The vehicle seized up while driving it, was lucky enough to pull to a side parking lot.

I had pulled out on a busy highway during high volume traffic. Approximately 1/2 block down highway, my Optima started to make a "sputtering" noise. Then the engine died while I was driving. I didn't have time to get to side of road. I ended up stalling going approximately 40 mph while the vehicles behind me slammed on their brakes to avoid hitting me.

Optima

Car just stopeven thed while driving down street in town. Engine light came on as car died, no prior warning. Car had been serviced regularly with no problems detected. Kia technician at dealership stated that engine had seized. Blamed engine problem on improper maintenance even though I had proof of regular on schedule maintenance. Kia refused to honor warranty. When I looked up problem on computer found that there had been several complaints of this same problem and was attributed to faulty engine design causing metal shavings from bearings that clooged oil portscreating sludge and eventually engine failure. Kia representitives stated that they knew nothing of this problem and again denied to honor warranty in negotiations.

Engine failed in may of 2016 (engine rod failure and knocking). Kia voided our power train warranty and said we would have to pay $6000 for replacement. The vehicle sat for close to a year until the recall notice was leaked. Due to the vehicle sitting in our driveway Kia said we would have to pay for all issues found outside of the engine. We paid $1497 for those repairs and drove the vehicle for one day. That same day we got a check engine light and "Kia of orange park" said the transmission sensor is bad and we have to pay another $400 for replacement. The engine was replaced with no charge but Kia is stating that our vehicle did not qualify for the recall. We made payments on a vehicle for close to a year and still are a single car family. We are looking to recover the funds spent on this vehicle.

Optima

  • 169,000 miles
I was driving my 3 yr old Kia Optima at 55 mph on a two way road with no shoulder and the engine suddenly and violently started knocking and shaking. I lost all power to the car and was nearly hit from behind as I slowly tried to come to stop on the side of the road with no power. It was scary as heck and I am glad to be alive. My car has been sitting at the dealership for 5 months as I try to save enough money to have a new engine installed. I still owe $8,000 for this car and the Kia dealership wants $8000 to put a used engine in it.

My car started smelling like burning plastic and then it completed shut off. Thankfully I was already in a turning lane when this happened. I only had 60K miles on the car at that time. Seemed like after my engine was replaced my windows stopped rolling up. Then my fuel pump went out. I noticed that it felt like someone was pressing on my brake as I was trying to go and then my traction control light would come on. We fixed this. Now it not even a year later and its doing it all over again. This is not safe as people are behind me when this happens.

Optima

  • 57,600 miles
I was driving home from work on a quiet residential street when my 2012 Kia Optima ex suddenly quit. I coasted into an office parking lot where I saw smoke coming from the engine. I exited the car, opened the hood and saw that the engine was on fire. Suddenly, the flames hit the fuel line and the engine exploded shooting flames 10 fee high. I was desparately trying to get everything valuable out of the car while calling 911. It took 4 firefighters to put out the flames. Thankfully, the whole automobile wasn't consumed. It was deemed a total loss. This vehicle only had 57,600 miles on it and was still under manufacturer warranty.

Optima

  • 91,115 miles
I was driving down the highway and my 2012 Kia Optima lost power with no warning signs. I had it towed to a mechanic only to find that the motor was locked up. Did I mention that I had just bought the car from boyles auto sales in jasper, Alabama on February 3, 2017 and the car quit on February 26, 2017 not even 30 days since the purchase of my car. Unfortunely, since we paid cash for the car the dealer basicly told us he wouldn't do anything. So now I am without a vehicle and having to find more money to replace the motor in the car that this dealer sold me. After further research I have learned that Kia has problems with the Kia Optima's for several years and the 2012 that I purchased is included. The mechanic told us that all the components of the car that should have oil, water, any type of fluid was fine but that something internal had stopped operating and caused the motor to lock up.

Optima

Loud knocking sound coming from engine, then check engine light came on. Made to dealership and discovered a bad oil pump caused metal to flow into the engine and wear the connecting rods and destroy the engine. Kia knew there were problems with the 2012 Kia Optima 2.4L engine and yet did nothing to rectify the issue. Now they want me to pay $6000 for a new engine when they knew there was an issue with the 2012 Optima all a long.
