Engine light is on the dashboard and can not conduct the Emission Test. I was told it's a oil consumption problem. And that the same problem that the sorento and sportage is doing. That is currently have a lawsuit going on. I was told the engine may start knocking soon. I was also told at shop that can cause the sensors to get false reading and send error signals to the engine also. If the engine cut off while driving or stall it can put my life and others in danger and cause a major accident. It was confirm at shop and I was told it's a recall on the engine. The dealership tells me not for the credenza and it's doing the same things as the models that is being look at and had a lawsuit going on. My cadenza is wrll6keot and under miles and should not be having this problem. Kia should help me with this problem. Please help me with this mattet.

  • 17,629 miles
The front glass roof panel/sunroof exploded with no evidence of any outside force or factor. Car is a 2014 Kia Cadenza purchased used in 2017 with 10,000 miles. Mileage at time of incident was 17,629. No relevant maintenance history associated with the incident. I was driving the vehicle in ridgeland, ms southbound on a frontage road off of I-55 at 6:20 pm cst at a speed of approximately 55 miles per hour in drive as the vehicle has an automatic transmission. It had been an overcast day and at the time of the incident it was not raining and the temperature was near 60 degrees. There were no cars on either side of me nor in front of me for a reasonable distance. As I was driving, there was an extremely loud explosion which sounded as if a gun had been discharged in or near my car. I was extremely startled by the explosion and immediately heard outside noise and felt air coming in from the top of the car. I slowed and engaged my hazards until I could get to a location to inspect the car. I noticed an interesting smell directly after the incident but could not determine where it was coming from and it dissipated. Once I parked the car it was as expected, the front section of the roof glass had a large hole with glass shards and the remainder of the front section of glass was cracked but had not dislodged. The rear glass section appeared to be unharmed. Three work employees as well as my wife witnessed the damage directly after I parked. This was a trip I had made numerous times with no unusual road conditions, traffic or weather in this case.

Engine was making a noise and fowl odor from vents took to Kia dealer after a wk they didn't know the problem said it was safe to drive back to las vegas from calif once we arrived we called local dealer they replaced engine so they said. Then 2 wks later we get it back I began having site throat cough and severe headaches and later told my husband I thought it was gas I was smelling in the car we took it to the dealer they looked at it and said it was fine so we leave to calif and the following day I went to start the car and we heard a loud noise and gas had gone every where the fire dept had to come assist and give clearance to tow the car due to the fuel hazard.
