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.

HEV warning light on, car monitor says possible MCU failure. I just bought this car. This car is in perfect condition, no accidents all service actions in order but the warning lights make it seem like the electric engine is about to fail.
The car can slow down suddenly in the middle of traffic even if I accelerate. The engine has a problem according to the mechanics who was trying to fix my car twice without succes. The car does not hold coolant liquid for more than 15 minutes. It looks like the coolant is staying somewhere in the engine. It overheats too. Yes the car is available for inspection upon request. It's a high risk because the car can suddenly slow down in the middle of traffic or when leaving a light turned green. And the last time I drove it there a weird smell. Yes, an independant service center located at College Park Maryland informed me about the issue. The vheicle or compenent has not been inspected yet by the manufacturer, police, insurance representative or others. When the car starts slowing down in the middle of traffic, I feel a kind of vibration first on the gas peddale and comes up the engine light. This happened last month
On Kia Niro, there is a part called the Exhaust Heat Recovery System (EHRS). This part pumps coolant into the exhaust system. If this particular piece fails, coolant in then pumped into the exhaust, burned up, and exits through the tail pipe. This piece failed on my car, which lead to coolant being burned in the tailpipe without my knowledge, which ultimately lead to no coolant in the engine and overheating and breaking down on the highway. After a full engine replacement, my car is still rapidly going through coolant. I imagine that this could lead to a car fire. I still have the faulty part installed in my car, however I am looking to replace it asap. While not 100% confirmed, my dealer is "pretty sure" that piece is what is causing the rapid loss of coolant in my car. This piece has not been inspected by the manufacturer, police or insurance representatives. There were no warning lamps, messages or other symptoms to alert me to this problem. I only found out about this piece and its failure rate after a full engine replacement.
I was driving on the freeway. After slowed down and stopped completely, suddenly it lose power to run. Trying to step deeper the gas pedal, but no reaction at all. After turn off and turn on engine few times, it can run again, but this time, the real problem occur. The engine sounds so loud..it's hybrid car supposed to so quiet (that's what sounds usually). Later on, I found out how to still can drove it, but with high risk suddenly lose power on the street. Later found out, when the car in motion, the hybrid system didn't worked completely, and the transmission sound very rough. Every time when come to brake or want to slow down, can feels obviously and heard the transmission is very rough making clutch loud sounds. The cruise control system also totally not function. When in stationary, very first when started the engine, made loud sounds on the engine, and can't reversed or move forward, just stayed in place. The dashboard display "check hybrid system". And on the middle screen displaying, "low voltage dc / dc converter".
Engine/transmission becomes very sluggish as temperatures drop and the transmission seems to be "engine braking" the vehicle, making coasting nearly impossible. Putting the vehicle in neutral allowed the car to normally coast but once back in drive, acceleration was taxing. The vehicle lacks any power and is ruining the fuel economy trying to get the car up to speed.
