2023 KIA RIO Engine Problems

I’ve been hearing this rattle noise mostly when I crank the vehicle. I took it to go get checked out and they heard it when I first brought it in for them to check. But when they got it to the back for mechanic to listen for it, of course it didn’t do it. They kept my car a whole day to try n find the issue/hear the noise and was unsuccessful. I’ve been told that it could possibly have something to do with the car timing or something with the engine. My car only has 34000 miles on it and it’s making this noise. They won’t approve me to trade it in or anything to help fix the problem or get me in something better.

The contact owns a 2023 Kia Rio. The contact stated that while driving 40 MPH, the vehicle lost motive power. There was no warning light illuminated. The contact pulled over to the side of the road and restarted the vehicle; however, the failure persisted. The vehicle restarted; however, the transmission failed to shift into gear. The vehicle was towed to the residence. The following day the contact was able to start the vehicle and the vehicle was taken to the dealer to be diagnosed. The dealer found no failure with the vehicle. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 100,900.

When I started my car, during the warm-up process, it dropped revs and turned off. After several tries, it turned on. While driving, when the vehicle was stopped, it began to jerk slightly. The safety risk is that the car, while I am driving, could turn off and cause an accident, in which people could be at risk, including me. I wouldn't want this to escalate because the dealer doesn't take action on the matter. The vehicle was taken to the dealer to evaluate the condition, they say that the technicians did not find anything, that the car did not emit any codes. And therefore they couldn't do anything. Note that I bought that car completely new, 0 miles, in March of last year. And in January the problem started. It is also worth noting that the car had to have a rack&pinion change in less than a year, due...
