I was driving my 2015 Kia Optima hybrid with around 77,000 miles on the interstate at 70 mph when the HCS, battery management system and other hybrid battery warnings flashed on the screen. The display said to pullover over immediately and turn off the engine. The hybrid battery charge display went from mid charge to zero charge. The car went into limp mode with very limited power. Fortunately, I was able to get off the highway as there was an exit ramp close by. After turning off the car, it would not start again. I disconnected the 12V battery hoping it would clear it out but that didn't work. Had to get car towed to the Kia dealership. They replaced the hybrid battery's high voltage 125 Amp fuse with a 150 Amp fuse and the problem was fixed (cost of $370). A search on the internet revealed that this is a common occurrence on 2011 to 2016 Kia hybrids and Kia knows about this faulty/inadequate fuse problem but refuses to issue a recall. Kia issued a TSB #PS-515 DTC P1B25/P1B77 -€" 125 AMP HV FUSE INSPECTION that states to inspect the resistance on the factory 125 A fuse and replace if less than 1 Ohm resistance with new 150 A fuse. This is a relatively simple fix for Kia that could prevent a dangerous situation if the car were to lose power on a crowded interstate.

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.

The Bluetooth Ring volume is ear piercing loud. When a call comes in on a paired phone it startles the driver and may be loud enough to damage hearing. If adjusted to a lower setting the call volume can-€™t be heard. When adjusting call volume to a usable level it increases the ring volume again so the next call has the load ring alert. Kia has a TSB# ELE 100 (REV4) on the issue but expects the customer to pay for diagnosis and software update to an out of warranty radio. Instructions in the TSB indicate this could be corrected with a USB software update. Most customers could install themselves from a software download if provided. In my opinion it is a safety issue and a recall should be issued.

When I drive my car it smells just like it is burning or melting in the motor, it comes thru the vents and smells awful. It has only smoked a couple of times when I have turned it off. I have had it looked at but at first they couldn't find the problem. The second time I had it checked out they said that the changed the HECU on my car but it still smells like it is burning. It has been doing it for about 3 months.

I-۪ve completed the recall on Saturday it took them less then a few minutes even though the invoice said 0.00hrs. I showed that I had brake fluid leaking and the car smokes but was told to come back if things got worse. Saturday night I was driving to the house with my fianc̩e and the car started slowly if down, the check engine light came on. Then the car shut off in the middle of the highway after a while it just cut back on and smoke all the way to the house. If there was someone behind me I would have cause a accident but it not within my control. My car has randomly shut off while driving and a while later coming idling again, today making the 5th time with in 3days

The contact owns a 2015 Kia Optima. The contact was driving at 75 mph, when she slowed down to 50 mph to switch lane then attempted to accelerate however, the vehicle would not exceed 60 mph. The vehicle was driven for about 2 more miles before it was towed to an independent mechanic to be diagnosed. The contact was informed that the alternator needed to be replaced. The alternator was replaced however, the vehicle failed to restart. The independent mechanic then contacted a Kia dealer and was informed by the dealer that there was a recall for the vehicle with NHTSA campaign number: 20V519000 (service brakes, hydraulic). The vehicle was then towed to parkway family Kia (22555 us-59, kingwood, tx 77339) to be diagnosed. The mechanic determined that the engine failed and needed to be replaced. The dealer determined that the failure was due to the recall. The dealer then sent the diagnostic findings to the manufacturer for the recall repair approval however, the manufacturer informed the dealer that because the contact had not done the manufacturer communications product improvement upgrade: Vpi1802 (engine) the recall would not be honored. The contact stated that she never received the notification from the manufacturer about the product improvement upgrade because it was sent to an old address that she no longer lived at. The vehicle remained at the dealer unrepaired. The approximate failure mileage was 143,000.

When you accelerate, for example to pass another vehicle, the vehicle will completely shut off, all lights illuminating on the panel the vehicle. The vehicle must be placed in park and restarted. Sometimes it starts right away, sometimes it takes a few minutes.

I was headed to ky December 2020 to visit my father. The car started making rattling noise. As I hit the gas petal, the car was stopping in on coming 1-65 traffic heading North. I pulled over and had to call my insurance company to tow to the nearest auto repair shop. I was nearly 50 miles from bowling green Kentucky (12-23-20). I called my insurance and we set up arrangements for towing to pick up the next morning (less than 24 hours- christmas eve). Within less than 24 hours, the car was impounded by Kentucky police near glasgow, ky. After paying towing fees and tickets, I finally got my car to auto company to run diagnostics report. After completion, I found out the engine failed along with more stuff. I immediately called the dealer who sold me the car (Kia-huntsville, al) to ask for advice on next steps. He told me to contact the nearest Kia service department near where the car was immediately to get it fixed because of the recall on the vehicle. The car was finally towed to martin Kia (bowling green Kentucky). They put me in line to have the vehicle properly and completely fixed. On January 4, 2021 the vehicle was in Kia possession to fix recall repairs. March 6, 2021 I was scheduled to pick up the vehicle because it was promised that the vehicle is completed. After picking up the car, I had to wait 45minutes because my car was locked and tire light came on. I was pulled to side and told the vehicle was fixed by brand new employee and to check to make sure a engine light does not come on because if so, it's probably the new hire fault for it messing up. After all of that, I was headed home and the car stopped a second time! after contacting local police, I was told to go back to Kia to return the keys and make them tow the vehicle to get it off of the interstate.

Driving North bound on the 405 at freeway speeds, the vehicle showed several warning lights on the dash. Check engine light, oil light and 2 others, the vehicle lost engine power and only had brakes. I was able to shuffle off the main freeway to an off ramp where I pulled over to attempt to power the car back on. The smell of electrical fire started to become apparent and I went out to lift the hood and smoke began to come out the opening. I rushed to get my kids out the vehicle and attempted to pull the battery cable off to try to salvage it from catching fire. I was able to wiggle the battery cable off but smoke continued to come out. The vehicle was eventually dropped off at the dealership car pros Kia in glendale and im being informed the starter was the issue and will need to be replaced. Im uncertain about the diagnosis since the event of the vehicle losing all power occurred during highway driving.

About a month and a half ago my traction control light came on and I lost power steering. For a brief period of time that day the light went off and I regained power steering. Later that same day the traction control light reappeared and has been on since causing me to lose power steering. I have spoken with the manufacturer and they claim that this problem does not fall under any recall therefore they are not responsible for anything.
