05/11/2023 Driving on Highway (Work Zone) Dash Flashed Hybrid System Failure - I was in the fast lane with Tractor trailer in front, behind, and alongside me - Gas pedal stopped working at that point nothing worked - managed to coast to the shoulder (could have been killed) Had it towed to Hyundai - They checked the computer and said nothing was wrong. that means if we were killed - Hyundai would be off the hook and they would say human error because they said no faults were stored and the codes were clear

I have a 2022 Hyundai Tucson with about 15k miles on it. I have had it serviced twice for oil changes and the recommended manufacture recommended maintenance. However, I have noticed a SIGNIFICANT loss in power upon acceleration with this vehicle. My new car drives very rough and this is a safety issue due to the fact when entering the interstate, the car will not increase speed as requested putting myself and others on the road in danger. Additionally, simple maneuvers like turning into cross traffic are of concern because the vehicle doesn't respond to acceleration when accelerating from 0mph as well as in stop and go traffic. There are no engine lights or codes that I can visibly notice but even in sport mode the acceleration of the vehicle is not responsive. This is a KNOWN issue at Hyundai as one local dealership offered me a service visit 6 months out because they are so overbooked with these issues. A quick Google search also brought up numerous owners experiencing similar and and escalated issues to include complete engine failure and vehicle overheating. This vehicle needs to be recalled immediately! I experience this loss of power EVERY SINGLE TIME I DRIVE and I don't feel safe driving my new car anymore. I have mentioned this to my dealership and they are going to take a look at it today. Occasionally, the car will also indicate to me that I should keep my hands on the steering wheel when I typically drive with BOTH hands on the steering wheel.

I have noticed this only happens on very cold days and it has Happened 7 times now. The car will be driving along and suddenly lose all power to the point you cannot accelerate above 15 MPH even if you floor the gas pedal. While this happens the Battery indicator will drop to 0 and then a Message Check Hybrid System pops up. Once the car comes to a complete stop the parking brake will automatically engage and will not release. If you shut the car off and turn it back on, A message please wait while battery charges is on the display and will not disengage the parking brake until the battery charges up to about 35-40%. The dealer has looked at the car 4 times and found nothing as no codes ever registered. I even opened a case direct with Hyundai Consumer affairs and they can not seem to find anything wrong with the car nor do they think it is an Issue. I find this to be extremely unsafe for a vehicle to randomly lose power and refuse to come out of park regardless of where on the road you happen to be when this occurs. It has not happened since the temperatures have been above freezing, but with winter a few months away. I completely fear for my safety.

An engine alert go off to Refill Inverter Coolant. However, Coolant was full. When temp Gets hot 93+ seems to trigger alert. There is a technical service bulletin Hyundia issued -??22-HC-002H-?? REFILL INVERTER COOLANT WARNING LIGHT ON. TSB says to flush system. About 100 people posted on this issue. Post mention two types of coolant used a pink in newer models and blue in older 2022 models. Some mentioned replacing coolant pump. Apparently known issue and not appropriately addressed by Hyundai and Kia also has this issue, same engine platforms in both.

My car broke down on the highway, found oil leaked out. Oil Plug fell off during drive making immediate oil loss which in result caused catastrophic engine failure. Vehicle needs new engine. The car received service maintenance in authorized Hyundai City of Bay Ridge Dealership. Car is less then one years old with only 4500 miles on it and oil plugs are not supposed to fall off the car without any apparent reason.

My pregnant wife-??s 2022 Hyundai Tucson lost engine power while on the interstate with our 16 month toddler in the car. Luckily she was able to get off the interstate and into a safe parking lot. The car only has 23000 miles and has been kept up with Hyundai-??s scheduled maintenance from their dealership. The engine is knocking and experiencing rough idle. Once I arrived I was able to read that there was an engine cylinder 2 misfire. About an hour later the -??MyHyundai-?? app sent the same error codes. It took the tow truck driver 15 minutes to go 10 feet to the flat bed as the car would turn its self off. Incredibly dangerous for a car less than two years old. I hate that I might-??ve gotten my wife and son such a dangerous vehicle.

On two occasions, both on busy highways traveling at about 65mph the engine just quit running. Very scary but fortunately was able to drift to the side of the road and wait for assistance. The car was towed to the nearest dealer two hours from my home. After the fuel injectors were replaced it was returned to us two weeks later. It only had 9,000 miles on it. This is a very dangerous problem to just stop running with no warning. We could have been hit from behind and killed.

I bought a -??22 Tucson Hybrid in Sept of -??22. Upon delivery there were issues w paint & a dent on the rear qtr panel. The bigger issue however, is disconnect in communication between the EV motor, gas engine & transmission. All work is done @dealership and well maintained. History of EV over 8 months: @1000 miles noise under vehicle began. Dealership inspected, all checked out. The dealership has done all servicing as scheduled. From 1000 to 12,000 miles, the vehicle drove best if in sport mode. Sport mode utilizes the gas engine and not EV. When in EV modes, the vehicle runs high rpms or it-??s sluggish. It-??s never consistent. In some instances; the vehicle will actually stall for 2-3 seconds and kick back on. 1 instance was at a stop light, turning left. Mid turn, gas to the floor, the vehicle stalled for 3 seconds before responding. I was almost hit at 50 mph in the intersection as both motors failed me. The next day, 3 lights came on: An EV, check engine and Hybrid motor light came on, 3 total. My Hyundai app stated: issue communicating EV and Gas motor, EMS communication error. This cleared itself in 36 hrs but I couldn-??t drive it safely for a week. I took it to the dealership, everything checked out. 3 days ago @ 17,400 miles, I received a text: Hyundai stated car unfit to drive. DTC code U062300, U111200, U02BB0:Powertrain EMS issue. The techs had it 2 days, fixed it. 3 blocks from dealer, check engine light came on again. I returned it to dealer. I-??ve found 32 accounts of these codes resulting in a Hyundai buy-back, new engine, new transmission or settlements. I-??m told my EV motor, gas engine and transmission won-??t communicate even after software / firmware updates & mechanical changes. I don-??t feel the vehicle to be roadworthy and I don-??t feel safe driving it, if Hyundai has no fix. I-??m told, many sales of this model @ my dealer have the same issues. Bad batch? I paid $47k (car & warr) I-??m hoping for a buy back or to get into a Toyota hybrid of = value

Within only two weeks of purchase this new car would suddenly stall in the middle of the road. The computer tells you to pull over. We continued to try and get the dealer to fix this issue, they first ignored us, then they secondly tried and successfully replicated the issue. They said there is no way they can fix the issue. This dangerous stalling in the middle of the road happened numerous times. You will push the pedal all the way to the ground and it won-??t go over 20mph. This is a very dangerous issue and these vehicles need to stop being sold. It is very dangerous. We have been left without our money back and without a car to drive for months. We cannot drive the Tucson as it is simply too dangerous and must be towed to go anywhere for salvage.

2022 2.5L HTRAC Tucson (Current Mileage: 27,088) This issue became notably clear roughly around the 12,000-to-15,000-mile mark on the vehicle. It's also worth mentioning that since month one of ownership, the vehicle has displayed some unnatural characteristics. Under hard throttle the engine created a tone that was very much discomforting and not confidence inspiring. It was abundantly clear the engine struggles to move this heavy AWD vehicle. The vehicle is so aggressive when it comes to shifting up to the next gear, I find myself doing 38-40 mph and the vehicle would be in 8th gear. When I would try to accelerate naturally the vehicle growls and vibrates and makes crunchy sounds as it struggles to accelerate against 8th gear. It's gotten so loud it can be heard over the AC and low volume radio. It's across the board as well, this issue occurs at highway speeds down to neighborhood driving. It will wholistically shift into too high of a gear whenever its possible, and the only way to prevent this experience is to manually shift the vehicle. This demonstrates that the driver is smarter in shifting requirements over the TCU. Furthermore, the gas milage for the first 12-to-15,000 miles failed to meet the specified expectations, additionally, the computer is aggressive in its calculations for the achieved MPG, and hand calculations tend to show they are off by 2 to 3 mpg consistently. I took the opportunity to change the oil in the vehicle early (1,500 miles) knowing that break in periods could have small metal build up as components seat and find their mark etc. To my Suprise, I was met with a substantial (in my opinion) amount of rolled metal material and metallic material in the oil. I took pictures and videos and decided to continue to change the oil every 2,000 miles to document changes. Currently the vehicles last oil change was at 25,000 miles and there is still a concerning amount of metallic material and occasionally rolled pieces of metal during oil changes.

I was driving on the highway with my ACC (Adaptive Cruise Control) and Lane Keeping Assistance on. Suddenly, I heard a loud noise from the engine. My vehicle was slowing down and was not able to accelerate. As I was pulling my vehicle on the side of the road, I saw oil warning light and check engine light on at the dashboard.

- Duluth, GA, USA

Went to get state inspection sticker and when there ask them to check the oil, because every time I checked the oil it showed over filled. The dealership checked it show over filled when they checked it and put it on rack to drain the oil and put some of that oil in a bottle. Told me would need to get approval from hyundai to fix the issue. Two days later hyundai refused to fix problem said there was water in the oil pan. Then accused me of driving the vehicle through high water to which I never have and told them so, but they refused to find out how water is getting into the oil pan. They said all the fluid levels are normal, so they don't know where or how its getting in the oil pan. I bought the car from the same dealership brand new and have had it 1 1/2 years and only have 2475 miles on the vehicle.

When driving my car at any speed it will suddenly begin to get sluggish then it becomes unresponsive to me giving it gas and starts to decelerate. When this happens suddenly warning signs on the vehicle go off stating to check the hybrid system and stop the vehicle. When this happens the car then stops functioning. I never know when it is gonna happen. I have been in the middle of heavy traffic and at high speeds stuck in the middle of the road. I have brought it in now four times to different dealerships and contacted corporate and No one can find a problem. I have pictures of the warning signs going off, all I am being told is we don-??t find anything wrong when they run their test or try to reproduce the issue, so they can-??t help me. This is a very serious and dangerous situation to be driving a car that has and will stall at any given time.

On Tues Feb 7, 2023, I was traveling at approx 6:50 pm on a suburban street at the posted 35 mph limit. My car started to lose speed, slowing to 27, then about 22-24 mph. I felt as though the engine was misfiring for an unknown reason. Since I was approaching an intersection and needed to make a left-hand turn, I started to depress the brake pedal. With no oncoming traffic, I slowed not quite to a stop, made the turn, but then had extreme difficulty getting the car to accelerate, again with the engine sputtering, chugging like a misfire, and shaking. My vehicle did not seem to go beyond 15 mph, and slowed again as I turned into my destination, about 2-3 blocks from the intersection. I parked and locked the car and was in a store for approximately 10 minutes. When returning to my vehicle, it would not start-the brake pedal could not be depressed at all, it appeared extremely hard. After 1-2 minutes of gently tapping the brake pedal, it loosened and I started the car. I put the car in reverse and it stopped in the middle of the parking lot with cars almost hitting me. I saw Engine Warning lights, Battery Warning lights, and a quick message across the screen but was unable to capture the meaning. After several more attempts, the engine started but was shaking violently, but I could not go beyond 3 mph. The shaking was so strong, items on the passenger seat shifted on the floor. I chose to remain in the parking lot and call Hyundai Bluelink. Since it was dark, I remained in the vehicle with the engine running, but excessive smoke billowed from the rear of the car. It was towed to Gerald Hyundai in North Aurora. After 3 days the dealer could not find any issue, however, I refused to take the car back, as I could recall it misfiring in previous weeks but unfortunately dismissed it. I requested a Technical Case File be opened at the Dealer. I still do not have my car after 1 week. This is a very serious issue and I am aware other owners have experienced it as well.
