To make a long story short on 5/16 my engine started to knock. Without any warning no prior warning lights came on no nothing my car started to stall on the highway I had my 3 year old daughter in the back seat and we barely made it to the side of the road. My engine, oil, and battery light started to flash and I lost power. I had my car towed to the dealership on 5/19 because I was made aware of a class action lawsuit for the exact same thing that was happening to my car. I bought the car 6 months ago from hickory hollow kia in Antioch Tn they made me aware that I had an extended warranty on my engine to have it towed in so I did that. I got a call from the dealership the next day telling me they needed approval first from kia to cover my vehicle. It would take them a week to do a diagnostic test which is what I-??m waiting for now and will update asap

Went to turn on my ac being a warm day and no cool air I called the collision center they then decide to tell me they are waiting on three parts still the ac compressor a part for the bumper and the turbo sensor. Meanwhile since it is a insurance claim I cannot have them check the recall part. So I made a appointment with Fred beans Kia in langhorne pa for the recall and a oil change they had the car all day to tell me that I need the part and it will be ordered that was April 23. Meanwhile Iam still driving with expired inspection. I then noticed my car started to shake and make loud sound when started and is feeling like Iam going to stall out and it does. It feel safe me being a single woman I don-??t want to get stuck I called bot the the collision center and the dealership inquiring about the parts ordered and now my car is running horribly one pointed the finger at the other leaving me worried scared frustrated and upset. Please help me.

- Gilbert, AZ, USA

The vehicle was purchased from Carmax on or about 4/10/21. On or about 3/25/22, the vehicle broke down while being driven. It was towed to the Coral Springs Kia dealership for assessment. A representative from the dealership advised that the engine needs to be replaced due to "rod bearing failure". The representative further advised that the manufacturer is refusing to cover any of the costs associated with the repair, which the dealership estimates to be $6,289.50 (see uploaded repair estimate). I believe the manufacturer should be liable for the costs of repair, which fall within Product Improvement Campaign PI1802.

Hi my wife was driving home from work when she heard a noise from under the hood her car then shut off for no reason on the highway, she started the car again started driving then the engine light came on and shut the car off again once again on a busy highway making it hard to pull over she made it home but engine was knocking checked the codes and it had codes for your rod bearing issues on the year before code p0014 and code p1326 not sure if anyone else had this problem but this is definitely not safe! For a vehicle to just shut off first no codes or anything making it dangerous for the driver and the people around the driver this matter really needs to be looked at, especially when someone almost gets into an accident bc the car just shuts off and is almost impossible to merge off the road and stop. Consumer's vehicle is the same model, up to the year, and had the same recall and defects that happened to his car.

Engine/motor failed which disabled the car on highway. Traveling on 3/4 lane highway with heavy traffic. Safety was risked due to almost being hit from behind and cars swerving out the way. Problem was assessed and thought to be repaired but occurred again causing more possible damage to engine. Warning lamp illuminated seconds before the car shut off which was not enough time to pull over safely. Car had to be towed off highway.
