The air bag just came on a couple days ago . it hasn't been in an accident or anything. the suspension is rough when driving over the smallest thing in the road. sometimes it just makes a little jump when it tasked gas.

There are a few recalls on my car. an appointment was scheduled to go to greenway kia in longwood, fl. however, upon arrival they tried to charge us for the diagnostics and stated that the recall is not valid without us paying for the diagnostics. then they proceeded to advise us that the parts that we needed under the recall were not covered by the recall and that we would need to pay thousands of dollars to then mention that it would be easier for them and cheaper for us to just buy a new car. we decided to leave and try to do more research. i did call our mechanic he confirmed there were recalls for our vehicle. i then called another kia dealer and they advised there were recalls on our car and that there would be no charge for the diagnostics and/ or repairing the car under recall.

I was driving in the evening at 25-30mph on a city street. there were no parked cars, no oncoming traffic, no pedestrians or bicycles for three blocks ahead of me. without any forward collision warning or road hazard, my car's autonomous emergency braking (aeb) system initiated and applied full braking force to my car for no reason. the car beeped continuously and flashed a red "emergency braking" notification in the dash console. the vehicle anti-locking braking system engaged in response to the applied braking from the aeb. i was unable to control or stop the braking during the event. once the car was fully stopped, the red dash notification stopped, the beeping stopped and i was able to move my car to the side of the road so traffic behind me could proceed.

Most recently while driving my car with vehicle in motion on city street (a straight road) it all of a sudden drops power and i am unable to get the car to accelerate without push down very hard on the pedal until it finally decides to speed up, once this occurs the traction control light appears on the dash and does not disappear and will not disappear until the car is shut off and restarted and the loss of power continues to happen until the car is powered off. after realizing this issue i turned off the car and let it sit a few minutes and when i powered back on and drove again the same issue occurred and the traction light reappeared on my dash. i am concerned this could be a faulty programming issue that is telling the car the traction is needed when it is in fact not. this is a safety hazard as there is no way to predict when this power loss will happen and does so in the middle of driving which slows the car way down and could cause an accident and also having to continuously keep the accelerator down until it decides ...

I have a theta ii turbocharged engine 6 speed manual and i was driving down the street taking my son to work. all of a sudden my car started making a loud knocking noise and wouldn't go past 2nd gear. we called a tow truck had it sent to mechanic they did a diagnostic test and 2 p codes came back from crankshaft and controls and seized engine. so i had it towed into weston kia dealership. plus i had just bought this car in april. the dealership ship called me saying they were going to replace my engine and wiring and computer and sensor chip. also my passenger air bag light has been blinking off 3 days after i bought it and still is. my emergency brake doesn't work and rolled while it was pulled up in neutral and hit my daughter as she was running around the front of the car to the passenger side right in her knee cap. i got my car back from weston and it didn't feel right. someone put 380miles on my car it had a 1/2tank of gas and my clutch and clutch pedal and gear shift was way shorter and 1/4 ...
