POWER TRAIN
There is a defect with the transmission control module (TCM) and dual-clutch transmission (DCT). This defect prevents the car from properly accelerating from a stop. The defect manifests in the following ways when pressing the accelerator: unresponsive or sluggish acceleration, jerking, shuddering, failure to shift, stalling and complete loss of power. Typically, the TCM defect manifests in two ways: shuddering/delayed brake release, which has happened over 20 times and loss of power/engine revving out of gear which has occured three times. These issues are unpredictable, unrepeatable and dangerous. I usually experience them while waiting at stop lights in busy intersections. Delayed and unpredictable acceleration and shifting could cause a traffic accident. I've notified the dealership three times and had it serviced once by licensed Hyundai technicians at the same dealership. They couldn't replicate the issue and claimed they had never heard of the problem. There are no warning lights when this issue occurs and the dealship said there were no diagnostic codes indicating the problem. Defective TCM & DCT software is a known issue that resulted in a recall campaign for the 2016 Hyundai Tucson. This issue has been documented in the following vehicles: 2017 Hyundai Elantra Eco, 2017 Hyundai Sonata Eco, 2016 – 2017 Hyundai Tucson, 2016 Hyunda Veloster Turbo. Hyundai issued the following service bulletins informing dealerships about the TCU software issue specific to the Tucson: #5NP-X7J3D-10, TSB# 16-01-035, #5NP- S9D9P-10

ELECTRICAL SYSTEM
The 12v system in my vehicle is defective, resulting in the vehicle failing to operate. Since I have only operated it about 4 times, i am unable to state whether the issue would occur while the car was being driven. I have had the car checked by the dealer twice, and it is now at the service department with an unknown date for "repair". The diagnosis from the second dealer service department directly conflicts with what the first dealer service department said. Additionally, I have discovered that this is a known issue with this vehicle model, and Hyundai has failed to address it. I have filed a formal complaint with Hyundai, as the vehicle is still under manufacturers warranty. Incidentally, there is a newly issued recall that I suspect is related to the 12v system, as well.

ENGINE
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.

The contact owns a 2021 Hyundai Ioniq Hybrid. The contact stated that upon starting the vehicle, the auto-hold warning light would illuminate on the instrument panel. The contact had taken the vehicle to a dealer however, the mechanic was unable to determine the cause of the failure. The contact was informed that he had to pay a diagnostic fee to service the vehicle. The manufacturer was notified of the failure and referred him to another dealer for assistance. The vehicle was not repaired. The failure mileage was approximately 4,000.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CATALYTIC CONVERTOR
I have put around 31K miles in my car. Day before yesterday ( Nov-2 ) when I was driving back home from work, suddenly I heard a noise. I pulled over and stopped the car. when I got down and checked, I noticed exhaust system or something similar to that fell off and touching the road. I have seen similar issues posted in Hyundai Ioniq forums https://www.ioniqforum.com/threads/very-dissapointed.37027/ https://www.ioniqforum.com/threads/first-issue-exhaust-fell-off-at-21k-miles-2019-phev.35092/ I will attach few pictures that I took during this incident.

ELECTRICAL SYSTEM
06/08/21 first day I brought my new car Hyundai Ioniq 2021 model at Hyundai Lincolnwood. After use the car about 2 months, the engine light has been showing up that something wrong about the auto hold and EPB. So I made an appointment for inspect in the next day. 09/21/21 - they were called to let me know that the car had been fixed and it was ready to pick up. So I went to pick up around 3.00p.m. after checked my car and about to leave the dealership, the auto hold engine light was show up again. So I had to take my car back to fix it. After have been waiting my car to fix about 2 months. I haven’t received any updates from them. 10/21/21 - the GM called me. So I went to the talk with him. He said the cost to fix my car about $5,000. I have to pay for in order to fix it because my warranty not cover for the break. I wondered why I have to pay even though it wasn’t my false. I brought this car and used it not over 3 months. Hyundai should take responsibility for the fixing cost not me. So I denied to pay. Then he left and brought me my car key and said my car was outside. Then I went out from the showroom and found out that the car he brought wasn’t mine. The car he brought is white color but mine is grey. So I checked on the white car and found out that the car was show the auto hold engine light with the same as my problem. So I guess I’m not the only one that had this problem even though I asked them earlier that has anyone had the same problem as mine and they said no and insisted that my car was the only one that have this problem. 5 minutes later, the GM came back with my actual car. And I end up the day by got my car back with the auto hold engine light still on. The GM didn’t care about this issue. He didn’t care about customer’s life and seem to care about the circulation more than fixing problem after sale service. Now I still wondering why the factory keep producing the car model even though i found a lot of consumer complaint about it.

SERVICE BRAKES
When ABS engages briefly on a wet surface, there is an incomplete transition from regenerative braking to friction brakes, resulting in a hard pedal that does not actually engage the brakes. This is very dangerous and I have experienced this loss of braking force multiple times when stopping in the rain and a tire is on a slippery manhole cover or crosswalk line. Braking force is reduced significantly for a second or two until the friction brakes are engaged. If the vehicle is rolling in Neutral, the friction brakes work as designed with no delay. It is only during normal driving when the regenerative braking is involved that this issue can be replicated.

SERVICE BRAKES
The regenerative brake system failed to operate as it normally does, and no indicator lights came on on the dashboard. This unexpected loss of braking force nearly caused me to hit the car in front of me. I had recently disengaged cruise control and was approaching a red light. I pressed my foot on the brake pedal and felt no response from the car. I lifted my foot and pressed again two or three times with no response, neither deceleration nor any change in the regenerative braking meter on the dashboard. I had to press the brake all the way to the floor before the mechanical brakes were activated. This loss of braking power greatly increased my stopping distance and I narrowly avoided hitting the car in front of me. Once the light turned green, I accelerated and tested the brakes again and everything seemed to be working fine, including the regeneration meter. No indicator lights of any kind came on during this incident. This occurred approximately a week ago. I have owned the car for approximately three weeks, and have not experienced any similar issues in the two weeks prior to the incident or in the week since. I have not yet taken it to the dealership as I would not be able to reproduce the issue for them. I will gladly cooperate with any inspection needed to better understand this issue.

SERVICE BRAKES
This issue is easily repeatable, when braking if you hit a bump (pot hole, etc.) the braking power is greatly reduced & the brake pedal becomes almost impossible to push down to stop the car, making it very hard to stop even when not coming to an abrupt stop.

ELECTRICAL SYSTEM
The traction battery on my Ioniq 2020 went bad after 3 months. The diagnostic panel warned me of an electric issue and the range dropped drastically. The dealer changed the battery no questions asked. My vin wasn't part of the recall. I wonder if the recall should have included a broader range of vehicles.

On June 10, 2021, when driving from Topeka, KS to Park Ridge, IL, there was a failure in both the Adaptive Cruse Control System as well as the Lane Keeping Assistance System. The ACC system started the car moving forward from a complete stop without my intent and the LKA turned the car to the right striking a semi trailer that was completely stopped. Additionally there was no warning from the Forward Collision Warning system

SERVICE BRAKES, ELECTRICAL SYSTEM, VEHICLE SPEED CONTROL
THIS IS A FOLLOW UP TO COMPLAINT NUMBER 1# 1360258 SUBMITTED IN SEPT. IN PARTICULAR, I HAVE HAD MULTIPLE DEALERS REPLACE A WATER PUMP AND RELATED ASSEMBLIES FOR A TOTAL OF 3 REPLACEMENTS SINCE AUG. THIS WAS THEIR EFFORT TO DEAL WITH THE ELECTRICAL SYSTEM ISSUES THAT HAVE RESULTED CONTINUED INCIDENTS OF ERRATIC AND UNCONTROLLED APPLICATION OF THE REGENERATIVE BREAKING (NOT BY DRIVER), SHUTTING OFF OF ANY ABILITY TO ACCELERATE THE CAR WHILE DRIVING, AND COMPLETE SHUTOFFS OF THE CAR WHILE DRIVING ON FREEWAYS, I.E. ALL LIGHTS OFF, NO RESPONSE FROM INSTRUMENTS EXCEPT FOR BREAKING TO A STOP. I REALIZE YOU MAY BE SHORT HANDED DEALING WITH COMPLAINTS, BUT I HAVEN'T RECEIVED ANY CONTACT SINCE FIRST REPORTING THIS AND WAS WONDERING IF I SHOULD EXPECT ANY? OR IS THIS ONLY ONCE YOU HAVE SO MANY RELATED COMPLAINTS TO INVESTIGATE? OR PERHAPS YOU NEED SOME MORE VERIFIABLE DOCUMENTATION OF THE EVENTS? THANKS FOR YOUR HELP.

APPARENTLY, A FRONT-END COLLISION OCCURRED WHILE THE VEHICLE WAS PARKED AND UNOCCUPIED IN A PARKING LOT RESULTING IN $1232 IN DAMAGE TO BODY PARTS, ANTI-COLLISION RADAR, AND ELECTRONIC CRUISE CONTROL. ASTONISHINGLY, THE BUMPER AND EVEN THE FRONT LICENSE PLATE SUSTAINED ALMOST NO VISIBLE DAMAGE WHATSOEVER. SEE PHOTOS ATTACHED. THE COLLISION MUST HAVE HAPPENED AT EXTREMELY LOW SPEED AND IT IS OBVIOUS THE FRONT BUMPER DID NOTHING TO PROTECT THE REST OF THE CAR--ITS PRIMARY INTENDED FUNCTION. THIS WOULD BE THE EQUIVALENT OF A HOUSE BURNING DOWN TO PROTECT THE FUSE BOX. I CHECKED YOUR WEBSITE AND NOTE THAT THE HYUNDAI IONIQ IS AS YET NOT RATED. I SUSPECT THERE IS A SERIOUS SAFETY ISSUE FOR A CAR TO SUSTAIN SUCH DAMAGE IN A PARKING LOT WITH ALMOST NO VISIBLE DAMAGE TO ITS PRIMARY PROTECTION MECHANISM: THE BUMPER. PLEASE NOTE THAT ITEMS DAMAGED WERE ALL IMMEDIATELY BEHIND THE BUMPER--A VERY DANGEROUS PLACE FOR THEM TO BE.
