I have a used 2019 Niro PHEV. I started getting a loud jerk when starting from a full stop. At first it started happened in EV mode only but I've had it happen in Hybrid mode a couple of times ( not sure if the engine is actually working or just on for Heating). The sound and jerk can best be described as what happens when you drive a stick shift and you pull the clutch too quickly in first gear without any gas and the car jerks forward. It also feels like I've been rear ended. The car feels unsafe the drive. There were no warning lights. Dealer hasn't reproduced it yet. I just brought it in. Please see these forum posts about this issue. Many others are experiencing this: https://www.kianiroforum.com/threads/brand-new-2019-phev-loud-jerking-noise-when-starting-from-full-stop.8740/ https://www.kia-forums.com/threads/occasional-hard-loud-shift-from-start-on-new-niro-phev.342780/

12 volt starting battery (Lithium Ion Polymer) pn 37507-G2120. battery swollen and will not take charge (2.5 years old) 15,000 miles on vehicle. This battery powers dash and all related safety systems. Dealer refuses to look into problem as batteries are on national back order status and cannot fix due to parts availability. 3 dealerships have been contacted, all have been making excuses for other systems at fault to avoid recognizing battery is defective. I have been without use since Mar2021.

There is a pause upon acceleration from a stop (unresponsive). Then the vehicle will lunge forward and make a loud noise. For both driver and passengers, it can be quite startling and feels as though the car has been hit from behind. This started happening in the fall of 2021, when the car was about two years old with about 18,000 miles. It has happened about a dozen times in the six months since first noticed. It seems that this may be a software issue related to the hybrid system - a lag in triggering which motor to use for acceleration.

Starting battery (which operates the safety systems) was getting progressively worse until vehicle could not be started. Upon inspection it was determined that the 1.5 year old starting battery was swollen and defective. NOTE: Vehicle did sit for 12 months in estate litigation.

I don't know what components are involved. When attempting to move forward from a stop the car does not respond immediately. Then there is clunk noise and a lurch forward. Sometimes when this happens it feels like the car has been hit from behind. The problem began about a year ago and has been into the dealer's service center several times. I believe during one of those service visits a reset of something was done that seemed to resolve the issue for several months. The problem is intermittent. Dealer has been unable to reproduce the issue, but stated the last time the car was in for service that another customer with the same year and make was having the same symptoms and a tech that had been allowed to use the car for over a week did not experience the issue. No warning lights or codes are associated with the issue. A car that fails to move forward on a green light is in danger of being rear-ended placing the people in the vehicle and surrounding vehicles at risk of bodily injury. The vehicle has not been inspected by anyone other than service staff at the FOlsom Lake Kia dealership. On February 18, 2022, the vehicle had no power (automatic doorlocks didn't work, etc) could not be started and was towed to the dealership where it is now.

The problem that I'm I'm having is a code P0456 (evaporative emission system leak detected, which is a small leak. The reason why I'm worried is because the gauge for the rpms goes all the way across as far as it can go, in other words it's like as if I'm pushing down on the gas pedal as far as it can go, it does this when I'm driving on the highway, when I'm about to leave a signal light from a complete stop, when I'm driving up a hill is when it's worst.

First the air conditioner stopped working for 2 days. Then on the 3rd day, 8/13/19, the hev light and oil lights went on. The engine slowed down. The car was towed to the Kia dealership in Ontario, ca. Initially they said it may not be covered by warranty. Then on 8/17 they told me the air conditioner needs a new compressor. Then on 8/23 I was told that oil and metal shards had leaked into the engine and the entire engine needs to be replaced. It is unknown when the repair will be done.

As I was driving on the highway, the ac stopped working. There were no warning lights, alarms or indicators that something was wrong, but I immediately got off the highway because I thought this is not right. As I braked on the ramp, the car still worked, but when I tried to accelerate leaving the ramp, there was no power. I got into an adjacent parking lot and turned off the car. When I tried to turn it back on, it was completely dead. I called aaa, they gave it a jump, but even though the battery was full, when put into drive or reverse it would do nothing.
