When attempting to acceleate rapidly, as if passing someone, the car will decelerate and eventually die, leaving you stranded on side of road or in the highway.

2012 Kia Optima snow white pearl paint. A few months ago the paint started bubbling and then flaking off. There are areas all over the car with bubbles and missing paint. This is a latent defect in the paint process, not a warranty issue. Every area of the car is affected. Kia needs to accept responsibility for their defect and fix this paint problem.

I contacted the Kia dealership in Wexford, PA on November 18 regarding the HECU safety recall and was told there is no fix available. The date of the notice was November 14, 2023 and I still haven't received an update from Kia. I haven't seen the MIL or ABS illuminated in my vehicle, but have experienced a slight burning smell over the past two days. My family's safety is paramount so I'm filing a formal complaint with the NHTSA. Kia America must address this issue and provide an immediate solution.

Dec 15, 2023Steering

The MDPS steering motor flexible coupling on our 2012 Kia Optima has deteriorated and a metal to metal clunking noise is made when turning the steering wheel left or right. See Kia Technical Service Bulletin (XXX) dated August 2016. Stated in the Bulletin is warm ocean waters in high humidity areas from Texas to South Carolina causes the problem. Apparently, those warm ocean waters and humidity do not go further north carried by the Gulf Stream and the warmer spring ,summer and fall seasons ; up to Long Island in NY as well as up to Maine. Kia has extended the warranty from 5 years/ 60,000 miles to 10 years/unlimited mileage for vehicles in other states but not from the TSB year of 2016 when the issue was first documented. So our 2012 is not covered because 2022 is over. Please note , our car has 40,000 miles and has been garage kept. This mileage is 20,000 miles less than the 5 year warranty while the 10 year warranty mileage is unlimited. This steering part needs to be made into a mandatory recall by Kia.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2012 Kia Optima verdict →
