Recall states to not drive vehicle due to HECU which can result in an engine compartment fire. I have contacted 3 dealerships and corporate. There are 15,000 dealerships/service centers that have technology/technical issues. I have spent 3 days, and 12 hours trying to get assistance. I'm being told corporate is not providing any additional support or payment to individually owned dealerships. Expecting them to cover additional expenses. I am disabled and need to go to treatments/procedures multiple times a week. They are backed up 1-2 months for an appointment. Consumers are to pay everything up front and then 90 days later request a reimbursement. They will not provide or pay for a rental or loaner car until the car is being serviced. Therefore they are leaving me with no vehicle for up to 2 months as their letter clearly states that the vehicle is not to be driven and is unsafe. I should not be inconvenienced because Kia made a mistake and is now having to perform a recall, 15,000 stores are not able to perform because of technical issues, they are so far behind in their service appointments which should not have any effect on me and I should not be responsible to pay for any of this and they should absolutely provide me with the vehicle and not leave me with no transportation for 2+months. I am unable to get to my appts. for treatments, my daughter cannot Drive to work. And they have absolutely no solution for me and telling me that there is nothing that can be done other than me paying $45/day out of pocket. they Stated that I personally would be charged to do a full diagnostic test to confirm that there are no safety issues, however corporate stated that it was required in order to get my car back. This has been an absolute nightmare, I am also wanting to know if ada would get involved in something like this as they are not making any type of reasonable accommodation for me. There has to be a law preventing this that they are required to provide a vehicle unt

On [XXX] while driving my oil light came on. Since I assumed I was low on oil, I proceeded to nearest gas station, approx 10 min.away, and added oil. I let engine remain off for approx.20 min. When I started the car up blue smoke began coming out from front and rear and there was a knocking noise. Since this is an engine that had already been replaced due to a recall, and now symptoms have returned I suspect engine might have failed again. I have always done my oil changes and have not had any issues. I had car towed towed to San Jose and contacted a mobile oil service to have oil drained out and replaced. When he was finished he said there were particles in oil removed and suspected engine had failed and I should not drive.

Unknown. The vehicle has this recall and Kia still doesn’t have a solution. It’s been more than 6 months and I want to ensure my car is safe to drive. I am unsure if there are any issues with my car, I am simply just wanting a remedy for this part if the car is being recalled.

Defect discovered by KIA September 2023 Affected owners not notified until November 2023 As of March 1, 2024, no updates. After six months, if no "fuse" is available, entire HECU should be replaced. Vehicle's exterior has significantly deteriorated since being required to park outside. Additionally, seriousness of fire hazard restricts use of car.

HYDRAULIC ELECTRONIC CONTROL UNIT (HECU) can start a fire, I was informed not to park the car in a garage or near other cars, also it can also catch fire while driving the car!! I was notified months ago of this problem !! I called a KIA dealer that got me no where !! KIA recall #SC284TF

Feb 14, 2024Engine

Known recall since Sept 2023, but Kia has not provided any dealerships with parts to repair (we have tried multiple dealerships within a 2 hour radius). Only recommendation is to "Park your vehicle outdoors and away from other vehicles or structures until you have the recall performed" which is an unacceptable option for 6 months. Now check engine light is on and still no indication as to when it can be fixed. Kia is not offering a loaner or rental until issue resolved.

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 2011 Kia Optima verdict →
