My car has never had the gas mileage that is advertised; it-??s always been about 3-4 mpg less than the 28 mpg city/31 mpg highway. Recently, I had multiple engine system failures with the plug-in check devices at places like AutoZone saying my ignition coils were misfiring, and after bringing it to the dealership twice for about 1.5 months each time for a total of 3 months, they replaced the fuel injectors and a few other parts the first time before releasing the car to me only to have the same errors come back within 24 hours and I ended up bringing it back only for them to tell me the entire fuel pump system is shot and needed to be completely replaced and all fuel flushed out. Both times I brought it in they claimed it was due to bad gas, but after talking to my insurance, my claim agent concluded it was not bad gas as newer cars like mine have internal sensors that will completely stop the car from driving or even turning on if bad gas is detected to prevent further damage and that-??s never been the case for me. I-??ve always been able to drive my vehicle and the only noticeable issue would be my fuel mileage. I-??ve had the new fuel pump system for about a week now, and my fuel mileage is around 28-29 mpg, more than it-??s ever been since I bought the vehicle back in November 2020. I-??ve only ever had a max of 26 mpg no matter how or where I drive. I did find recalls on similar makes of cars with the same year as mine from both Kia and Hyundai, and I believe that the Kia Souls around 2020-2021 also have faulty fuel pump systems and should be recalled. I don-??t know how many of them are out there, but despite only having 50k miles on my car, the bad gas diagnosis excluded it from the warranty and I had to pay out of pocket the $1,516.83 for the fuel pump system replacement and flushing of the -??bad gas-?? at the Kia dealership.

The vehicle experiences a complete loss of power when slowing to a stop before it powers off on its own. The car powers off while going down the road. The car experiences partial loss of power while on cruise control and the car will slow to nearly stopped. The immediate loss of power puts myself and others at risk as the car is now stopping unexpected on the highway. I have left numerous voicemails for service managers at the dealership it was purchased brand-new from 2 years ago. They have not reached out to me. I had an appointment at their dealership to have the car inspected to see if this was covered with my warranty and they explained my warranty was only 60k miles and my car is now at 65k miles. The car was shutting off and having power loss a week before the first indicator light came on, which was the engine light. The code pulled for that sensor was the P0171 sensor which measures air in the fuel system and it stated "bank 1 running lean". I have now taken the car to a local shop and they are advising there was no oil in the car and there are metal shards in the valves in the engine. Werner KIA is the only shop that has ever worked on my car or changed the oil and they have not advised me of any oil leaks at all.

I am very concern with the 2021 KIA Soul that I drive presently. The vehicle is in my son-??s name; however, I pay the monthly payments and I am the primary driver for this automobile; this is also listed on my insurance policy as well. I have been experiencing some dangerous mechanical conditions with the car. Please find a copy of my uploaded document summary. I have an appointment tomorrow, Tuesday, on March 22, 2022.

Two major issues. I have heard a very loud ticking sound coming from the engine which started about three days ago. Before then the car ran silent. Car is it approximately 8000 miles on the odometer. The clicking started getting louder and then the car stalled twice right in the middle of driving! one was on a street going about 45 miles an hour! the otherwas on a side street going approximately 25 miles an hour. The ec oh mode was on in the car. Also' when you turn on the heater fan on high it started making a high-pitched squealing sound. The car is at the dealership right now as it will not work properly.

I was going to get my mail attempting to park where I always park. I hit the brake and the car sped up and hit two mailboxes. I couldn't get it to stop. I do not know how fast it was going when I hit the mailboxes
