I received KIA letter about the recall SC276 for HCA issue around 1/15/24. I brought my 2018 Kia Niro PHEV to Kia Dealer in San Jose. They inspected and concluded that the vehicle is safe with the recall SC276. However, they did not replace the fuse as stated in Kia's recall instructions. Ten days later, I was on the road, slowing down at the intersection and the car suddenly lost power, the Dashboard show the message for 'EV System failed'. My battery was fully charged at work, which is 2 miles away. My gas tank was full and I couldn't start my car again. Lucky enough, I was 1/4 mile away entering a Freeway. I couldn't imagine what would happen if I was on Freeway. Police stopped by, put road warning while I scrambled to get a tow truck. An hour later, they was able to move my car off the road. The first Kia Dealer is 3 miles away. They, however, refused to service my car because the other Dealer in San Jose already checked my car for recall before. I had to tow my car 36 miles to San Jose Kia Dealer. I asked them to check again if it was the issue with the recall. Kia Dealer diagnosed and concluded that the 'Relay Assembly Power' unit, Fuse-High Voltage failed for whatever reason. I asked for picture of the damage part and haven't received them. The Dealer said they still have system message which Kia's Engineers haven't figured out why. I am on the 3rd week without a car. I don't have a car to go to work and pick up my kids. I am renting a car at $300/week for my family and work tasks.

On March 28, 2023 the vehicle HEV warning light came on. I called the dealership where I was informed they did not have any mechanics available to look at it until August. No one to work on Hybrid. I then took it to a mechanic shop, And I was informed to take it to the dealer. I could not drive the vehicle. I called KIA, Temple Hills back, I was told if you tow the vehicle here it will just sit. April 8, 2023 had it towed to another shop, the mechanic stated he thought it was the battery, which I was informed hybrid has 3 batteries, to check with the dealer to see if they had them, or could order one. Called the dealership Temple Hills, stathat they had never heard of a battery for that car. I was told to call back next week, after he spoke with the parts dept. manager. I called back a week later, and was told they knew nothing about a Kia Niro, could not help. The mechanic looked for a battery at other shops, ebay. The one I Paid 600.00dollars for did not work. After being there for 1 month. I called Kia dealership Bowie Md. On June 6, 2023 spoke with Jacob, the advisor. The vehicle was towed there, Jacob refused to give me any updates on the vehicle after 1 month being there, just sitting. I would call him trying to get updates, he informed me that they only had one mechanic, just a whole lot of nothing, the vehicle could catch on fire. Another month passed and I went to the dealership, along with my brother. Jacob was not answering my calls/returning them. Vehicle just sitting there. Jacob, then said the mechanic that worked on the hybrid was out for surgery, he would be in touch. I asked for the Kia Corporate number, which I received. I contacted Kia, corporate on July 13, 2023, spoke with them several times, informing them that the vehicle was not operable, and I was still making car notes/ paying insurance on a vehicle that I was not driving. At the dealership now for 3 months. Jacob, not communicating I can email you documents/fax, all paperwork.

My 2018 Kia Niro EX keeps overheating. We purchased the vehicle July 21st 2018. Three months after purchase, the vehicle dies, flashing warning lights and a message appeared to shut the engine off. Our car was towed to the dealership we purchased it from. After over three months, the dealership calls and tells us to pick the car up from them. The entire engine had to be replaced. We sued Kia Motors through the lemon law. We settled for the payment option because the engine was replaced. Now, our hands are tied due to once we took the cash settlement, we were no longer able to take legal action again if we had any additional issues. Over the course of the last three years, we had to have it repaired for a wiring issue, now, our vehicle continually overheats. Our dealership where we purchased the vehicle does not have a hybrid technician to work on it. We have to drive to another location of theirs to have it serviced. That location is over an hour drive. Our car is unable to be driven to have it properly service by the correct technician. There is an online forum, www.kianiroforum.com. This forum explains in detail what type of issue the consumer is experiencing with this vehicle. I am reaching out due to this overheating issue could cause serious harm to someone. We have spoken with Kia corporate headquarters, their advice is to have it looked at by a Kia dealership and they will go from there. We have exhausted all of our options to have these issues looked into and now reaching out to you for assistance. Myself included, it appears this vehicle has many many issues and needs to be brought to someone-??s attention that has the power to get something done.

No incident to report. Design safety issue. The design of the emergency liftgate safety release requires the use of the vehicle's mechanical key to exit the vehicle through the rear liftgate in an emergency (see owners manual page 4-26. The need to have a key in hand utterly defeats the intended concept of an emergency release. This design would be completely unacceptable for the trunk of a sedan and it should also be unacceptable for a hatchback or liftgate. A relatively inexpensive fix would be to install a simple metal lever in the door through the slot provided for inserting the key. I have had other vehicles with similar emergency release mechanisms. I do not know how wide spread this is through the industry or if there are in fact different standards. I would urge NHTSA to require manufacturers to make all doors openable from the inside without the need for a key or any other tool, especially where it is specifically identified as an emergency means of exit. Thank you for all your efforts to keep the driving public safe.

Purchased the vehicle with safety tech package which includes aeb (auto emergency braking) and vehicle did not stop even when I applied full brakes to prevent a collision. The main reason I purchased this vehicle was for this safety feature.
