“For the second cold morning this year my ioniq stalled. I was parked in my driveway. Temperature was -3f, I press the power button, car tried to start and stalled three times in a row then got a check hybrid system warning message. I turned the car off then on again and it started to stall, I depressed the accelerator to keep a high idle for a minute. The car ran normal during my 7 mile commute after increasing the I.”
NHTSA complaint #11183801, filed 2019-03, 900 miles“Recall work was performed to fix any possible overheating issues. A month later I notice me heater not working and then it starts over heating and smoking from the back, I take it in and they claim that it's just a bubble in the radiator. On 04/21/2020 about a month later without any warning lights prior it flashes that my engine is overheated and large clouds of white smoke starts coming out of my exhaust pipe. Hyundai service department said that because of a faulty switch coolant leaked into my engine and the engine is now ruined and needs to be completely replaced.”
NHTSA complaint #11322929, filed 2020-05, 13,383 miles“I am not sure who to report this to, but NHTSA and Hyundai corporate office both report the car as having no recalls. The local dealership says it has 3, 2 for computer errors (my car currently has a computer error). When I asked the main Hyundai support people about this, they stated local dealership and the corporate office have different systems. I can concerned Hyundai is hiding recalls from the public by keeping them on a separate system at dealerships and not on the main website or NHTSA.”
