2014 Kia Optima Owner Comments

problem #4

  • 14,050 miles


I purchased a Kia Optima in December of 2014. At 8,000 miles I noticed unusual wear on my tires, I had them rotated and balanced at 7,500. I recently went to America tires with the mileage at 14,50 they confirmed that the tires were worn down to less than 50% of the tread. They rotated and balanced them but the life of my tires is short. It appears that the tires are inferior. I feel unsafe driving my car. I have driven several cars however I have never had to replaced tires this soon on a vehicle. I have about 5 to 7 thousands miles left before replacement is needed. The tires in question are nprizah8. My fear is that several unsuspecting people are driving around on these unsafe tires which could cause serious problems. Especially those who don't have regular service on their tires. Can you tell me if there has there been any issues with these tires?

I was trying to back in between2 vehicles in the church parking lot. And while doing so, with my foot on the brake the car lunched backwards with a jerking motion, like it was trying to do 2 different things atone time, at full rate of speed and doing so, it backed into the vehicle to my left, the car acted like it had a mind of it's own. I reported the accident and when the police arrived on the sight, he informed me that he had seen an issue like this happening on the news. I had never heard of and I went online to report this incident. I was not hurt and if my cousin wasn't in the car, I don't think anyone would've believed me. I think this needs to be looked into, I'm really scared to drive my vehicle.

Optima 4-cyl

The problem is sporadic but happens frequently. If I press the gas pedal to increase my speed, whether from a stopped position, or to pull into a busy roadway, or to increase my speed to pass another vehicle, the car will start to go then choke, so that no matter how hard I press the gas pedal, the RPM stay the same and the vehicle loses power and will not speed up. If Kia doesn't figure out what is causing this - because I have seen other people with different Optima vehicle years complain about this - someone is going to get killed. I have had numerous near misses because of this problem. I also see many people saying Kia is telling them this is the way the vehicle is supposed to behave - really"?? my car is currently at the dealer to hopefully have the problem diagnosed and fixed. They gave me a loaner car, which is a 2013 Kia Optima, and guess what" pulling out of the dealership in the loaner I was almost rear ended because the loaner also has this problem, but 10 times worse than my car. It happened at least 30 times between the dealer and where I work - about a 30 minute drive. Always when speed needs to be increased by way of the gears needing to upshift. Please please please someone pay attention to this - I hope Kia isn't waiting for someone to get killed before they look into this failure that is happening that their dealerships are writing off as normal function! just as I was ready to submit this complaint, my dealership called me back and surprise: "we are unable to duplicate the problem" and "no problem codes were detected." Please Kia, take notice of this problem before someone gets killed!!!
