MY VEHICLE HAS 75,583. I received a recall for 3 items and made an appointment and took the car in for the work. I noticed that their wasa slight dead spot in the centeing of the steering and asked if there was any adjustmen. I was told there wasn't but they would check it because there was a known problem thith the plastic gear in the electric motor's connection to the rack that wears out and can completely disintegrate. when I picked up the vehicle they had obviously checked it because the slight dead spot had turned into a clunk. As there was no recall they would nothing about it as the vehicle was out of warranty (10 years, 100,000 miles). Had it had a higher annual mileage it would have been replaced under warranty. My concern is that this fault may be hidden by the warranty coverage. If the plastic gear fails completely the steering could become locked or inoperable. …
Vehicle suddenly cut off and lost power. Upon cutting back off check engine was blinking as well as oil light. Was left to sit over night as it wasn't safe to drive home and would not restart. The following morning the car started but was hesitant driven less than 20 miles home which struggled to accelerate and check engine light was illuminated along with oil light coming on . Oil was in the car at the time. Parked in front of home additional oil added oil light then oil light cut off until ac is turned on . Car was turned on and sitting and a knocking noise began . Left to sit the next day then taken to jiffy lube where a reading came on the scanner that it was the crank shaft was then ordered to go to a repair shop where it was diagnosed the engine is blown and that oil was basically being burned even with a maintain of oil changes therefore this caused metal to metal contact . …
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 ([redacted]) 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. …

The steering is making a clunking noise when backing up and going forward at low speed. There is a TSB by Kia about the steering motor rubber gear spacer that simply disintegrates over time but Kia is only performing repairs on vehicles in warm humid areas up to South Carolina. Why up to South Carolina? Being we live on the Eastern End of Long Island in Southampton Town in New York : we are surrounded by the Atlantic Ocean to the South and Long Island Sound to the North. On Long Island, the temperature frequently approaches 100 degrees in the summer and is very humid also. I would say we qualify for a recall based on what the TSB says. There should be a recall for every Kia Optima along the Coastal United States that has this issue as it could become quite dangerous. From what I have heard and seen on line , it is a multi hour repair for several hundred dollars. …
