On saturday 9/14/19 my daughter was driving on the highway when she heard a noise and the check engine/oil light came on and then a driver pulled up next to her and told her that the car was on fire. The engine ended up in full flames.

My check engine light keeps coming on. At first it would go off and on with no code. Now it stays on with the code p0420 for the catalytic converter. Also I heard about an air bag recall

The cadillac converter is gathering soot build up according to the garage. Needs to be replaced. Is causing the engine light to stay on.

My kia optima began consuming large amounts of oil but it wasn't leaking out or burning off anywhere. I began to watch the oil levels closely and was down 2 qts every week. At some point the oil pressure got too low and we think sucked air into the engine. The check engine light came on and then off again as it has been for the ppast yr but for an evap problem - a very small leak kept getting detected. I spent $1800 at firestone the previous ur the colder kept coming back on and off. But this didn't explain the sidden massive oil consumption. Suddenly on oct. 21 my car suddenly idled very high without moving and the the check light came on again and stayed on. The engine began to knock loudly especially when accellerating or climbing hills. My mechanic friend told me one of the engine rods was damaged and the computer code check verified that the crankshaft timing oil control valve was not working properly. This would explain the low oil pressure and damage to the engine. I was able to find the problem on kia's website with many complaints regarding the same issue. Kia had a recall regarding this problem for many of their cars but of course not mine. I was very upset over it. I had gotten the car only 3 years prior and it only had 150k miles on it. I took really good care of it. Kia said they could do nothing. My only option was to junk the car and have to buy a new when I wasn't in a position to do so. Kia has disappointed me greatly. Because of this problem I may never but another kia. I was so excited about getting my kia as it had all the features I wanted in a car and at a very good price but it iis only good if it runs. This problem should have been included in thw recall for my car as it is a huge problem as I read complaint after complaint online from other kia optima owners. The engine computer code that came up was po600011

I was driving to work and my drivers side airbag came on. A few months prior, we had to replace the o2 sensor because the check engine light was on. Now on the second day with the airbag light on, the check engine light came back on! Is it bad wiring, will my airbag not work?

Tl* the contact owns a 2007 kia optima. The contact stated that while driving at 50 MPH, the engine started to make an abnormal noise. The engine warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed that the main bearing in the engine failed causing one of the rods to fracture. As a result, the engine needed to be replaced. The manufacturer was not notified of the failure. The failure mileage was 125,000.

I came to a complete stop and proceeded to turn left when I noticed the check engine light came on and as I pulled over there I noticed a thick cloud of blue smoke out of my rear view mirror. I opened the hood and saw flames at the back of the engine around the transmission and airconditioner area of the car. Flames continued until the interior began burning and windshield broke.

I have a kia optima 2007, I bought it brand new in 2007. The air bag light is on and they have not fixed it under warranty at all. Also the engine light has come on and they will not fix that as well. I have had to change the rotors on the car only a year into driving it. The air bags will not deploy in the event there is a crash which is a danger to me and my kids. I have tried to reason with kia and they want nothing to do with me at all.
