The vehicle is currently at the dealership. I purchased the 2022 hyundai Tucson hybrid limited in April. Have gotten my oil changes done religiously at the dealership. Vehicle is at 22k miles. And had oil change 5 days prior to incident. I was on the way to work and vehicle started to struggle to accelerate, engine began malfunctioning. Vehicle dropped drastically from 80mph Dow to 25-30 mph in short period of time, would have been rear ended if not in right lane already. No warning or previous problems. No warning or check engine lights EVER came on before the vehicle would not drive at all. And was told by the vehicle to -??check hybrid system stop safely-??. Called roadside and vehicle was towed to dealership. They diagnosed as -??the timing chain was -??missing-?? one of the cylinders, causing a loss of power from the gasoline engine and the hybrid system attempted to compensate for lost power, resulting in engine failure-?? later that day when I arrived from work to get a loaner I was told that it was a broken camshaft and warranty would pay for a new engine.-??

On three separate occasions the vehicle refused to accelerate after being in a stop and go mode (I.e. traffic/drive thru). All three times an alert popped up on the dashboard stating: HEV Check Hybrid System Stop Safely. The second time this occurred a diagnostic code came up: DTCP112000. In all three occasions turning the car off and restarting resolved the issue at least temporarily. Also- the battery was completely depleted after each incident. Vehicle is at the dealership service center for the second time without and current diagnosis or solution.

Driving the car acceleration will go to zero. You can floor it and it will only go to 20mph. The car asked you to pull over safely. They hybrid battery is at zero and warning signs keep flashing. Has happened over three times on a new car. Dealership can-??t figure it out. When I look up -??HEV warning Tucson hybrid-?? there are many with same issue. Very, very dangerous issue.

While accelerating on an on ramp leading to the interstate, the 2022 Hyundai Tucson PHEV Limited was in the Smart Drive Mode and the vehicle was in Electric Mode only being powered by the electric motor. I noticed that the vehicle was struggling to accelerate to the interstate speed of 70 MPH, I pressed the accelerator further in order to gain more speed to safely merge onto the interstate. With the accelerator pushed all the way, the engine eventually turned on after 5-7 seconds assisting the vehicle to reach the speed of 70 MPH. Once on the interstate, I set the cruise control to 70 MPH but the vehicle was not able to maintain that speed. The speed of the Tucson started to drop suddenly and I then began to make my way to the right shoulder of the interstate. During the process of moving to the right shoulder, I did notice that the Power Gauge on the instrument cluster was maxed out, the vehicles engine was running at at very high revs, but I was never able to get more speed out of the vehicle. The vehicle was slowed to 40-45 MPH by the time I was able to reach the shoulder due to traffic. Once on the shoulder and out of the 3 lane, 70 MPH traffic, I was able to power down the vehicle and restart the vehicle with no issues. I then put the vehicle in drive and signaled to the left in order to merge back into traffic. I accelerated briskly to merge with the 70 MPH traffic and the vehicle did operate as normal. The vehicle began to move under EV power and the engine did turn on to begin assisting in moving the vehicle up to speed. The vehicle operated normally for the remainder of my drive, approximately 3-4 miles. During this event, the vehicle never did display any warning lights or messages on the instrument panel or the center screen. No warning tones or chimes were given either. The high voltage battery was at an approximately 68% state of charge and the fuel tank was approximately half full.

I am an active-duty service member who purchased a new 2022 Hyundai Tucson Hybrid on 16 October 2021. The car occasionally makes a strange humming noise while the vehicle is completely turned off. I recorded my car making this strange noise, and the video recording can be seen at https://youtu.be/bY8GJenoWBQ. I had previously notified Hyundai Maintenance of this during a scheduled vehicle check; nothing was done to resolve this matter. The advertised fuel economy on this car is 36/37/37 (city/combined/highway) Miles per Gallon. I am currently getting 28 MPG (see attachment), which is approximately 30% below the advertised fuel economy. Since I purchased this vehicle, it has consistently delivered a poor fuel economy well below the advertised fuel economy. After trying to resolve the poor fuel economy issue with Hyundai for 9 months (see attachment), I reached out to the Better Business Bureau seeking a resolution. On 17 November 2022, I was notified by the Better Business Bureau that Hyundai rejected my proposed resolutions of Hyundai repairing the car under manufacturer warranty or replace it if unable to fix the poor fuel economy, as well as reimburse me for money spent due to excessive fuel consumption. Additionally, other persons have reported their Hyundai cars delivering a fuel economy much lower than advertised (visit https://www.reddit.com/r/Hyundai/comments/nwayqv/2022_tucson_hybrid_poor_gas_mileage/). I have the perception that Hyundai lied and deliberately deceived me. Something is wrong with my car, and Hyundai has been either incompetent or unwilling to repair the issue under the car manufacturer warranty. I believe that it's important to hold companies such as Hyundai accountable. Otherwise, it would have no incentive for doing what is right. I request your assistance with investigating, and if possible, taking actions to hold Hyundai accountable for deceiving consumers by exaggerating its car fuel economy.

I bought this car less than 30 days ago, and it has 1,500 miles. I tried to start my car in the morning and when I put it in reverse, it just rolled forward. I braked and put it back in park and the engine shut off. I tried this a few more times before I gave up. A tow came and first suggested it was the alternator, before another tow came and suggested it was a sensor. It has been at the dealer for 48 hours without a diagnosis, -??maybe the injectors.-?? I am fortunate this happened in a parking lot and not while I was on the road. I am now terrified to drive this car.

What component or system failed or malfunctioned, and is it available for inspection upon request? Since February of this year, a few weeks after I purchased this car the center console has to be replaced...it is on order to be replaced since April due to rear camera malfunction (Hyundai of Bowie, submitted BBB complaint). A few weeks ago the emergency brake initiates randomly. And yesterday the Engine light is on. Yes available upon request How was your safety or the safety of others put at risk" I'm unable to see cars or people when in reverse. While taking off from a parked position, the emergency brake comes on and can cause me to crash or stop suddenly forcing someone to crash into the back of me. Has the problem been reproduced or confirmed by a dealer or independent service center" Yes, took the truck for repair back in April, still unresolved (center console), no response from them after they supposedly ordered the replacement part. The emergency brake issue just started. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others" NO Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" Yes, the rear camera would show previous images on the camera or green screen with lines. When the emergency brake comes on without being initiated by me, other lights come on as well. Now (10/24/22) the engine light is on!

1. What component or system failed or malfunctioned, and is it available for inspection upon request" The engine will not start despite having the key fob with live battery on my person. 2. How was your safety or the safety of others put at risk? I was stranded 3 times in a week in dark public parking lots with limited cell reception. I had to abandon the vehicle to get to a warm, safe location, and as a single woman, did not feel comfortable staying with the car while other cars were loitering at night. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The car has been with the dealer for 6 days now and they have not been able to replicate the issue and it has happened to me 3 times in one week. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear" No, there doesn't seem to be any rhyme or reason why the car won't start. After a few hours, the alarm sometimes goes off, and the system resets, allowing me to restart the car. Given this car has a push button start ignition, there is no mechanical way to crank the ignition to start the car, so I am left with no recourse. The last time this happened, I had it towed to the dealership because even after waiting 3 hours, the system did not restart and I had no recourse.

I purchased the vehicle 3/31/2022, & it left with recalls. I brought it BacK with 48hr, as the check engine light turn on, also the tires, dashboard, and overall the screen. Its been left at the dealer and no results. Also it has affected my life as a disabled handicap person as I'm unable to get to and from doctor appointment etc including to transport my scooter or wheel chair. its a nightmare. I came to purchase a car and was given a "lemon". with only 12miles purchased. I was directed by finance department to proceed with this matter for a resolution as we resolve this matter. The vehicle has been a problematic problem from the start. Definitely not standing firm on the customer Hyundai core value & warranty. The car is at the dealer and I'm temporally with a loaner on which I need to know all my option before we proceed. This is a very serious matter on which Hyundai is fully aware & infant they directed me to this process. My life was at risk as I was told to keep a car that is unreliable with a donut tire without repair. I felt as if I could've die if something was to happen to me within a week until service still count fix the tires as I was placed in jeopardy of my life & kids during Labor Day weekend.. Driving an unsafe vehicle. I was in concern since day 1!

My wife was driving on the parkway north in New Jersey at approximately 65 miles an hour at about 3:45 pm. The car began to lose power, was shaking, and sputtering. Luckily, she was able to pull onto the shoulder and did not get hit by another car or truck. Once she pulled over, she let the car rest for about 10 minutes and started it up again. It hesitated, but started. Once she put it in gear, it stalled. she tried this two other times and it stalled each time. she waited for a tow truck and the care was towed to the dealer. The dealer invoice with repairs is attached.

purchased new 2022 hyundai tucson plug in hybrid in december 2021. In April 2022 the vehicle with 5500 miles experienced loud transmission bangs and lost ability to change gears. vehicle then stuck in neutral in driveway unable to select drive or reverse. had vehicle towed to dealership. once at dealer, mechanic unable to replicate problem but was able to pull up trouble code history. mechanic was told by hyundai corporate technicians to reset the transmission to fix problem. Fast forward to July 21, 2022, vehicle started to flash several warning indicators on dash including forward collision assist, no left turn signal and check engine light and transmission once again stuck in gear unable to select drive or reverse( approx. 9000miles) Upon disconnect of vehicle battery was able to get vehicle into gear to remove from garage. All warning lights remained on vehicle for 4 weeks before I was able to get a service appointment to fix problem. at dealer on august 16, 2022, check engine light reset prior to arrival, once again dealer unable to replicate problem and was told to return if vehicle exhibited issue again. August 22, 2022, upon leaving driveway and while in drive the vehicle just stopped in middle of roadway. once again stuck in neutral and all warning lights once again lit up. vehicle pushed to side of road to get out of roadway. upon starting the vehicle several times and turning off vehicle, finally was able to switch into gear. Roadside assistance was called to tow vehicle to dealership, where once again no loaner cars were available. The vehicle has exhibited lack of power on several occasions as well. specifically when going up a graded road. on one occasion vehicle would not go over 10mph. The fact that the vehicle died in the middle of the road while under operation is a huge safety concern as if i were on a freeway or expressway and it just stopped it could have been catastrophic. please look into this issue before someone gets seriously hurt.

My vehicle that I finance is a 2022 Hybrid Tucson it failed at 14,596 miles I had it since November 2021 so for a good 9 months until it decided to finally malfunction. As I been driving it previously for the past month I-??ve been hearing the transmission struggle a lot more everyday that I use it. I also noticed that the engine really lacks power, when I accelerate it takes a really long time for the gears to shift which has been getting worse for the past month now. Which is what I believe led up to my vehicle losing complete engine power while I was driving 30mph. I saw on my digital cluster a message saying -??Check Hybrid System, Stop the car safely.-?? In an orange triangle, I had cars backed up close to me and I was confused as to why this was happening to my not even a year old vehicle. This is a major safety issue to me that while I-??m driving anywhere my engine will go completely off and I am only to rely on 20mph on EV Mode. If I was on the freeway I could-??ve gotten into an accident and with my whole family in the car. I personally feel unsafe driving, it-??s my daily driver and my only way to get to work.
