My Kia Sorento 2019 has been acting weird for a while. I had talked to the service guys and I was told all is fine. Here are some of the major issues: 1. the car has an issue of acceleration. Once it reaches 45mph it becomes noisy and it feels like the engine is about to explode. The answer from the service guys:" It is normal." 2. the brakes: It takes too much time to stop. So, even if I keep my distance from the car in front of me, I always struggle to stop at the safe distance at the stop sign or lights. The answer from the service guys: 'no problem with the brakes.' 3. after driving for an hour or so, the motor overheats significantly. 4. finally, the car rolled back from the parking lot (while on the park mode ) and injured two people, and damaged another car.

When driving at high altitudes, the car seems to want to stall. We will be driving along just fine and then there is hesitation for a moment and then the car will be going along just fine again and the hesitation happens again. This is continuous throughout our entire high altitude drives. Usually occurs at approximately 8000-10,000 ft in elevation. Seems to occur more often at 40 miles per hour. I am scared we will have complete failure of the car in the mountains and have no cell phone service in order to call someone for help. We have only had this car for about 6 weeks and have taken 4 high altitude drives and this happens everytime. Took the car to the dealership and they told us this is a known issue and Kia is working on it. How long will it take Kia to resolve this issue? I don't want stall somewhere and create a hazardous condition for myself, passengers, and others surrounding me. Please see Kia gets this taken care of as soon as possible for everyone's safety.

Leased the car in March and by end of may it was ideling rough and clicking. Got a message on my screen engine control system failure and a check engine light came on. Took it onto the dealer and with less than 2900 miles it needs a new engine. Now it will be about 3 months (they are backlogged) until I get it back!!

Car has problem when driving in econo mode. Will hesitate when given gas in morning and at times when pulling out in traffic. Note never informed about the problem before leasing of car. Told by service department that is the way it was designed. May cause problems for other drivers or accidents. Note by mileage was never test driven after so called fix.
