2016 Kia Cadenza owner complaints

On december 6, 2016 my sunroof exploded while driving down the freeway. The explosion was so loud and violent I thought I was shot. Shards of glass rained down on my head.

The contact called the local dealer, who stated there was no recall. The manufacturer was contacted and referred the contact to the dealer.

The Windshield is a defect on the cadenzas, as the seals break on them. It lifts up while driving or even shutting my doors, which I see as a safety hazard. It causes water to leak into the car by where my feet are and from the top of the windshield as well. I believe this is causing my car and other cadenzas to also have electric issues since i’ve had, 7 speakers blew, back up camera glitched and stopped working, sunroof stopped working and i’ve had signals / sounds stop working as well a shot throttle all before 24,000 miles.. Kia has been giving me a run a round with trying to fix my windshield and still has yet to do so. I see this as a huge safety issue. What happens if I hit a bump and it falls off when I’m driving? It could cause a huge accident and or killing myself and others. At

My 2016 Kia Cadenza (VIN [XXX] ) experienced repeated overheating, coolant loss, and eventually white exhaust smoke consistent with internal coolant intrusion. The issue began mid-2025 and worsened over time. Despite reporting overheating and coolant loss to Central Kia of Plano, the dealership failed to diagnose the problem, did not escalate to Techline, and did not check or apply Kia Service Action WTY039, which was active. They returned the vehicle to me still overheating, forcing me into multiple out-of-pocket repairs for coolant, radiator, radiator fan, and water pump replacement. None resolved the issue, and the vehicle became unsafe to drive due to rising temperature and smoke. A second dealer, Mesquite Kia, performed a proper diagnosis. Kia Corporate approved an engine replacement

While driving down the highway, I heard a loud boom and my sunroof exploded sending glass everywhere all through the car with my kids in the backseat. Driving straight on the highway at 60 miles per hour and nothing to hit the glass, Something is definitely wrong with the pano sunroof on these cars.

While driving, I heard a loud pop followed by a loud grinding noise. I wqs able to pull over and noticed the passenger front side of the car was lower than the rest of the car. At around 75k the passenger side strut went out. Fast forward 2 months later, driving my car the same thing happened but to the drivers side. Both struts needing replaced by 80k. Definitely should be a recall on these struts as this seems very premature and alot of other people with this car have had this problem.
