Fuel/Propulsion System · reported Nov 11, 2026
When driving on the highway a couple of hours from home we had noticed our check engine light had went on, immediately after our gas mileage had dropped significantly. Shortly after we had heard a loud pop and thought a rock had hit our car. We right away noticed our dogs crates were slanted and they were up and scared. I inspected to see why the crates were slanted and when I had turned around I had seen that that rear seats were popped up with a huge space inbetween them and the frame of the car. We immediately had gotten off of the highway and pulled over. With a quick google search as we…

Power Train · reported Oct 12, 2026
From the get-go seemed to have trouble with transmission once in a while Little jerk when shifting gears, reported this, they could find nothing. It has become a lot worse. It has caused the car to shut down into limp mode with engine light on. So I had a problem from the beginning with my new car. But when they check it, they can’t find a problem. So I’m just checking to see if anybody else with this car make, model, year have reported anything the same.
Service Brakes · reported Oct 9, 2026
I am filing a safety complaint regarding my Kia K5 because I am concerned about a potentially dangerous mechanical defect. I purchased this vehicle used from CarMax approximately two years ago. Within the first 30 days of ownership, the steering wheel began shaking. CarMax repaired the problem at no cost after ordering a replacement part. Approximately two weeks ago, the steering wheel began shaking again. The problem has now progressed to the vehicle shaking, feeling as though it is skidding or slipping, and failing to accelerate properly. The check-engine light is illuminated. I contacted…
