Leased this Kia by force from rightway auto here in Indianapolis in. Had for about 1 1/2. First notice after filling up my tank gas was depleted within 3 days on driving 12 miles to and from work in town. Then oil start disappearing a week after oil changes..around Jan 8,2024. Check engine light start flashing driving the highway to work. Speed jumped down to 45. Engine start shaking if I tried to go faster. Got a engine light scan says needs knock sensor. Had it replaced. 6 months later. Car did the same thing. Same code. Knock sensor. Had it re replaced. 3 hours later car did the same thing. Each time while driving the highway almost got me rear ended. On June 27,2024 took it to ray skillman dealership. Found out knock sensor needed to be replaced again, this time along with plugs n worse apparently knock sensor throwed off spark plugs. Was told it's consuming a lot of oil they don't know why cause there's no leaks. Spent over 800 at the dealership. After paying 320. Replace part. Then another 140. Replace that replaced part. Less than a week after spending 800 at the dealership. [XXX].on my way to work my car did the same thing driving on the highway where the speed limit I think is 70. Cars flying. And almost got rear ended again. Cause the speed of the car dropped to 45, engine light start flashing. Car started shaking.. so again I'm out of a car cause it has to go back to the dealership. Not enough money for lift to work n home. About to lose my job. Just paid my car note on the 23 of june at 700 plus insurance 175.. 1300 for rent. And a minimum wage paying job at the airport. Apparently the 5 yr warranty on the car is up when I just reached 10000 miles. And I only had this car for less than 2 years I think it had 90 something thousand miles on it when I got it..i guess the makers of this car knew this trash would only last 5 yrs. reason why it came with a 5 yr manufacturer warranty Can someone please help. We the people are out of money. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION

It is impossible to use the brake pedal if the shoe size is US10+. the distance between the floor and the knee airbag mechanism does not allow the use of the brake pedal.
