1 Check Engine Light On problem

Failure Date: 11/24/2021

Engine failed, check oil light or check engine light never came on. Had to put a new motor in the car and kia would not fix. Product update came on the car prior to us buying it, so we had no idea. Car stopped on a 2 lane highway with no warning, luckily noone was injured. There was a class action lawsuit regarding this issue, however it was already closed so nothing we can do. Kia is aware of the issue they should be responisble for fixing it.

2 Check Engine Light On problem

Failure Date: 12/13/2020

Driving north bound on the 405 at freeway speeds, the vehicle showed several warning lights on the dash. Check engine light, oil light and 2 others, the vehicle lost engine power and only had brakes. I was able to shuffle off the main freeway to an off ramp where I pulled over to attempt to power the car back on. The smell of electrical fire started to become apparent and I went out to lift the hood and smoke began to come out the opening. I rushed to get my kids out the vehicle and attempted to pull the battery cable off to try to salvage it from catching fire. I was able to wiggle the battery cable off but smoke continued to come out. The vehicle was eventually dropped off at the dealership car pros kia in glendale and im being informed the starter was the issue and will need to be replaced. Im uncertain about the diagnosis since the event of the vehicle losing all power occurred during highway driving .

3 Check Engine Light On problem

Failure Date: 11/29/2020

I was driving 70 miles per hour on i96 when the check engine light, the battery light and the oil light came on. I was able to get to an exit but the car cut off right at the exit ramp as I stopped traffic for a mile. The car would not start again and had to be towed. I had it looked at two different places and they said it was the engine. The car is a 2015 with slightly over 100,000 miles. Regular oil changes at the dealership and there was absolutely no warning that something was wrong with my car. I had never had any problems before. The last car shop said that something came loose in the engine. I could have been killed if I did not make it to the ramp. I called the dealership and they said they have been having a lot of problems with kia and Hyundai motors.

7 Check Engine Light On problem

Failure Date: 01/08/2020

My vehicle is among the vehicles registered/qualifying for a recall. My dealer was to have replaced my entire engine during the first recall my vehicle received. Within a week/some 5 days or so my check engine light was back on. Taking the car back to my dealer, it was suggested that I pay $145 just for them to do a diagnostic on the/my vehicle they had just serviced. My car is currently registered/qualifies for a recall that stems and or is related to the previous recall that my car had. . . As recently as a few days ago (1/8/2020), the same dealer supposedly �fixed� the recent recall. I'd went by the dealership, they serviced the vehicle - check engine light went/was off. I'd say what was an hour or so having the car back in my possession from the dealer, the check engine light was back on. I'm appalled at the fact that I'm currently experiencing a issue that has been on going over a year. In my research on recalls I'm not to be charged anything by law surrounding rectifying a recall. On more than one occasion my dealer has suggested that I pay after feeling that they've rectified the problem concerning my vehicles recall. I have valid third party diagnostics that interestingly enough were free, unlike the diagnostics my dealer would suggest I pay for on a car that is surrounded by a serious recall issue. And more interesting is my having received a diagnostic that rendered the results that are the same codes surrounding the recall, and this after/on a day/ the last day - my car was serviced/supposedly �fixed. � I'm appalled at the suggestion that I �upgrade,� into a new car, pay anything, how any car having received a �new engine,� though 5 days later the check engine light is back on - that's �scary. � I have necessary documentation that can show my dealer is oblivious to public safety laws surrounding recalls due to remedies they suggested on �fixing,� my vehicle.

11 Check Engine Light On problem

Failure Date: 12/21/2018

I was traveling at 65 mph on a straight and level highway in my kia Optima (which has less than 60,000 miles), the check engine light came on and I lost all power. I could have lost my life. Car was towed to local repair shop who determined that vehicle needed to be brought to a dealer. Barry henderson, the repair shop manager, said there is a possible wiring issue and if the wiring is okay, the engine needs to be replaced. He told me they couldn't repair so the car was towed to hyman brothers kia in midlothian, va. All required maintenance has been done on this car and hard copies of all of the service records have been place on the front passenger seat as proof.

12 Check Engine Light On problem

Failure Date: 12/17/2018

2015 kia Optima with approx 68,000 miles. Going up hill up a ramp to merge onto highway around 40 mph when the check engine light illuminated and would no longer accelerate. Shortly after, the oil and battery lights illuminated and car coasted as far as possible into shoulder as I could. Car would not restart. Sat on the on-ramp for quite a while partially blocking traffic and almost had some near miss accidents from other drivers passing and honking at me. Towed to kia dealership same morning. Tech believes my engine has seized but no official diagnosis. They provided me with a loaner car at no charge. I am original owner and hope kia will replace my engine at no cost and buy my car back. I am scared of the vehicle fires that are happening with these engines for other people. My car gave me no failure warning until it was too late.

13 Check Engine Light On problem

Failure Date: 05/16/2018

Driving down a city street less than a mile from my home, the car stalled just before the intersection. I could not restart the engine. There were no oil or check engine warning lights showing. I coasted to a parking space and checked the battery. All the lights worked but the engine would not turn on. I had the car towed to the kia dealer. They checked the car and said it was my fault because there was no oil in the car. I had the oil changed at 50,000 miles and the car has 56,000 miles on it. The car is still under 60,000 miles so the warranty should still be good but they refuse to fix it they did not give me a loaner car because kia refuses to pay for the engine. There is a recall on the ecu logic upgrade (ksds) which they installed in September 2018 along with a catalytic converter replacement, they are using any excuse so they don't have to pay.
