Owner's manual states the 1.6Turbo requires 4.75 qrts of oil with filter change. The car reads full after adding 4 qrts. Still reading full after double checking after 250 miles. .Owner's manual typo? . Incorrect dipstick during final assembly? .Following the manual could lead to overfilling/foaming issues and thus engine failure/safety issues. Perhaps a TSB needs to be done? Note: I used a Fram filter. Slightly smaller dimensions than original but in no way accounting for 3/4 qrts.
I was driving in the freeway nearby San Jose, CA with my family in the car. I was doing 67mph. It was high elevation curvy road. I experienced engine stalling. The car suddenly stop accelarating and speed drop to 35mph despite pressing on gas.
The Kia optima 2020 2.4 every 3000 to 4000 miles oil change is metal shavings in the old oil. The clicking noise stared it around the 10000 miles mark and now is getting worse with 60000 miles ,everytime I hit the gas and goes over 30 miles loose a lot of power and a clicking noise come out ,now is getting worse. Is a new car. Already change a ABS pump and I keep my oil change to the date. I m afraid the car is breaking . Help.
When I accelerate the car jerks as if is going to cut off. I have taken it to the dealer, and they can not find any thing wrong. After searching the internet, I find I am not the only one with this issue. I just want my car fixed so that I feel safe driving it.
