I purchased my car in 2015 at 23k miles, now we're at 86k miles and I'm experiencing issues. How is there a recall for this car but no remedy yet when there is a high risk of fire" Shouldn't there be a resolution for this safety concern" I noticed my car in 2022 would smoke here and there when driving, and I would smell burning. I took it to my mechanic and he changed the head gasket, and the smoking stopped. There is residue on my engine from a leak from the oil. My mechanic at the time told me I might still smell burning oil just due to that. As time went on things were fine but a year later, the oil smell came back stronger. I notice it only on longer drives, so I do believe my car is leaking oil. Also, the amount of time I've changed my break lights this year and head lights. They dim so fast over time and eventually go out to where I have to replace them. There is 100% an electrical issue going on.

Rear outer TAIL LAMP combination assemblies (NOT the inner lights on the trunk lid) have failed Virginia State SAFETY Inspection due to accumulation of moisture and standing water in BOTH left and right outer tail lamps, causing LEDs in the tail lamp assembly to burn out and not illuminate. There have already been multiple Technical Service Bulletins (TSBs) on the matter (i.e. KIA TSB PS364, KIA TSB BOD143, KIA TSB BOD172), and the cause outlined in these TSBs has been a DEFECT in design leading to a gap between the tail lamp housing gasket and the vehicle body allowing WATER INTRUSION. KIA has neglected to inspect, fix, or add additional gaskets per their instructions during eligible warranty periods, and extended warranties refuse to fix the issue as they classify it as water intrusion. This pins the financial burden to fix the safety issue on the customer/driver, as KIA dealers have quoted $1,232.46 for replacement of these tail lamps. What component or system failed or malfunctioned, and is it available for inspection upon request? Components: Rear outer tail lamp combination assemblies (both left and right) (NOT the lamps on the trunk lid). Inspection availability: LIMITED due to significant time pressure and inconvenience (since the tail lamps have caused the vehicle to fail Virginia State Safety Inspection, the car needs to be fixed ASAP to resume commute to work, etc.) How was your safety or the safety of others put at risk" Lower visibility for others, may result in incident. Has the problem been reproduced or confirmed by a dealer or independent service center? Confirmed by KIA dealer themselves. Also, multiple customer complaints on internet, as well as TSBs. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? KIA dealer did not inspect during warranty. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" No and UNKNOWN.

I have my driver side tail light out, when I bought the car in 2019, they said I have 30 days to bring in my car so they can replace what needs fixing, well I hit day 32 and I-€™ve had to replace my tires, brakes, headlights and tail lights because they all went out on my own dime, now my brakes are making me nervous because sometimes it feels like my car isn-€™t slowing down to a stop and I have to slam them to stop sometimes.

While driving at speeds higher than 45 mph, the steering wheel locks for a brief moment. This does not allow for a smooth way to keep the vehicle straight on the highway. Very scary. Antenna cover on top of car flew off on the highway. Read that it has happened to several other 2015 Optima models. Back up camera is foggy and I can no longer use it when reversing. Back taillights have condensation in them. I have already had one of them replaced early on.

I was traveling East on a 4 lane road at 45 mph. As I was passing thru a green light, a westbound vehicle made an illegal left turn in front of me, causing me to "T-bone" his vehicle. All of his airbags deployed.....none of mine did. The car was repaired, surprisingly; yet I do not feel safe driving it. I sustained cervical and lumbar spine injuries, as well as a severe whiplash and concussion. I am unable to work, due to surgery that was necessary. I just need to know if this car is safe?? I was also in a side collision that was not my fault; two years ago, where someone hit me, and no airbags deployed. At that particular accident, I was stationary; at a stop light.
