Rear door behind the driver’s won’t open inside or outside.
What is the estmated cost to fixing it?
My guess, less than $1000.00.
I would ask a body shop rather than a mechanic.
Body shop may give you an estimate for free.
A mechanic shop or dealership, will likely want to perform a diagnosis at a cost of $150-$200.
Unfortunately, you missed out on this…For Rear Door Latches: Kia is extending the warranty on rear door latches from 5
years/60,000 miles to 10 years/unlimited mileage.
