At around 40,000 miles my car started burning oil rapidly. No leaks were found and I would get an oil indicator light then the car would shut down while driving. I couldn-€™t get it to accelerate. Mechanic said Kia-€™s and Hyundais have been having those issues. I have needed oil changes every 3 weeks to keep in functioning.

I brought the vehicle into Kia service for the recall including a computer operating system upgrade. After the recall work was done the car driving at high highway speeds failed, and immediately slowed down, almost causing a rear collision. The computer system turned off the drive mechanism and I was left with only the electric motor to propel the car. The car barely limped off the highway. The car was brought to the Kia Dealer and no defect was found and the computer was reset. This problem occurred two more times, at highway speeds (70 mph) and Kia was contacted to find out why the problems occurred and how to fix it. To date, Kia has not responded to how to fix the problem and has ignored all phone calls and emails. The car has been in the shop for 3 months. The problem occurred only after Kia upgraded the software due to the recall. Additionally, the recall work was done. I do not know why the recall work was not reported.

- Apache Junction, AZ, USA

My car is consuming 2 quarts of oil for every 1,000 miles. This falls under the oil consumption that needs a motor replaced and I am getting a run around from the dealership about getting it replaced. They are saying that Kia does not like to replace the motors and I'm better off trading it in. I bought this car intending on keeping it long term, not purchasing a new one. All of the regular maintenance has been done on the vehicle. I've been into the dealership a multitude of times a month due to issues with the car.

Excessive oil consumption. Dealer says it is normal to burn a quart every thousand miles. At that rate I would have no oil left before my next oil change. That is not normal and could cause overheating and engine lock up. The car only has 45,000 miles.

First incident occured when I was driving to work. The engine made a noise and loss power which almost resulted in a crash. I contacted Kia, they explain to me that a knock sensor need to be installed and software needed to be updated. They installed it and return the car to me. Now again while I am on the highway I hear a loud knock, lights flashing in the car and the car has loss power. I rolled off the exit pull over and called a tow truck. While waiting I check the oil in the car thinking maybe the engine is locking up. There is no oil in the car, which is strange because two months prior Kia just did an oil change. I have documents to prove everything. Kia has been the only dealership that service the car. They now been in possession of my vehicle for four months now and nothing has been done. I contacted cooperate and they have failed to getting back to me after numerous attempts to get answers. Please someone help me. I have congestive heart faliure which I explain to them and I really need my car but most of all I need it to be safe for me.

One said they replaced parts and fixed - but still have issue and one did nothing but download software to get ride of code. The other 4 Auto Store has reset code which they should not be doing and sometimes say no. This has happened 6 times since I have owned the vehicle.

Engine overhead and stopped working in addition to it consuming massive amounts of oil without physically putting oil in. I've went to 2 dealerships who refuse to provide me with a new engine even though I'm covered under the engine extension warranty due to me having the knock sensor update done. I am now involving my attorney and will go to the news channels to inform how kia manufacturer has become a disgrace with not providing quality engines in their vehicles and don't want to be responsible for it. there's already a settlement going on for kia optimas and other cars they've made because of faulty engines. They can better believe I'm coming for them next with a lawsuit.

We would like to know what Kia is planning to do to address the fact that Kia built a car without the basic immobilizer circuit making it very easy to steal. Over the last few months, local and national news reports, as well as many social media sites, have reported on this security flaw which likely emboldens others to attempt a theft of a Kia and/or Hyundai. As I do not live in Milwaulkee, I would like to know how the company will fix this problem for the rest of us. It will not be restricted to just one city. There are numerous articles by victims that have detailed how their car theft cost them thousands of dollars in insurance deductibles, rental cars, and repairs. Many of the articles explain how thieves as young as 12 years old are able to still these cars in under a minute in broad daylight and driving recklessly creating a serious safety hazzard. Please advise what Kia will do to negate this serious security flaw.
