Vehicle would not accelerate leaving driveway. Was bucking as I went down the street. At end of street when I tried to turn off it stopped as I accelerated and I was almost rear ended. I pulled over there were no warning lights on at all. I pulled out as I wanted to turn around and go home and it would not accelerate again. I was able to make it home. I looked up problem on line and it seems like I am not alone. As it is Sunday going to call dealer tomorrow but not expecting them to take it in soon as most appointments take over 1 month to get. I am very scared to drive my car.

On 9/3/23, driver was waiting at a stop sign to turn left. When driver accelerated into the highway, there was no power and the vehicle would only go 5-10 mph. Warning lights came on to check the hybrid system with the HEV indicator light. Driver pulled over. Restarted car and engine was stuttering. Was able to drive a few miles to a safer location. Started car on 9/4/23, again it had a rough start. Driver waited until the vehicle sounded normal. The vehicle immediately lost power and could not accelerate when on the main road. Called Hyundai and they were unconcerned. We are in remote Alaska, 250 miles from a dealership. Because it happened on a holiday weekend, we have been unable to contact the service department yet. Vehicle is available to be inspected. Safety is a huge risk because the car suddenly stops propelling forward. I'm afraid we will get rear-ended because of the sudden loss of power. It is a danger to ourselves and others. I'm also concerned that we will be stranded because the car has to be stopped when this occurs. We were supposed to be enjoying a trip for a week, and now we don't trust the vehicle and will likely need to go home early and lose hotel costs. This issue will wind up killing someone because there are reports that these Hyundais are stopping in the middle of the highway. Please hold Hyundai accountable.

Car intermittently will loose power (shortly after commencement of driving). This will remedy itself by shutting off engine and restarting. This has happened 4 or 5 times within the fist 3,000 miles. This is a vehicle and traffic SAFETY issue that could cause lives!

- Orchard Park, NY, USA

The car shook and then lights and alarms went off indicating something went wrong with the hybrid system. The car stopped accelerating, would shake, and then accelerated no more than 10 mph. It was absolutely crazy! Luckily, the highway that I was traveling on was not a busy one at the time because all I thought was this could have been a major accident if on a fast moving freeway. I managed to pull over and started reading online about this issue occurring with other customers who purchased the same or similar vehicle. So, I found a post and had shut the car off for 5 minutes, then restart and sit for 10 minutes, and then the car should work. It did! However, during the time of waiting I did reach out to the dealership and they said if the car is working there is nothing they could do. So, I assumed it was safe to use travel to work for a meeting and set up my classroom for the start of the new school year. On my way home from school, the issue happened again. I immediately contacted the dealership and was able to get the car to them. They started running diagnostic tests and currently have the vehicle on hand. However, I don't really feel safe now with this car given the circumstances. What if this should happen again? What if this happens to me or someone else who is traveling on a busy highway and it causes injury or even death to an accident. The engine light came on, battery light flickered on and off, the car shook, the car's HEV system warning was going off, etc. Please help and look into this matter. I do not have any documentation of repair as the car currently sits at the dealership, but I was so upset thinking about what could have happened and felt the need to report the issue.

-There are 3 problems. The 1st and most dangerous, is a combo of the engine, transmission, and fuel system. The 2nd is malfunctioning sensors. The 3rd is water leaking in under my glove box onto the floor mat. The car upon 3 different occasions has stopped accelerating in the middle of traffic. 1st: the car would not go past 30mph and it stuttered/ shook. I parked and turned the car off, but 5 minutes later it reset and ran "normal". The 2nd time in Dec 2022, I was on Annapolis Rd.(Maryland) at about 10pm while alone. It would not accelerate past 35mph, the check engine light came on, and the engine/transmission started shaking and stuttering. I was almost rear ended so I pulled over. The next day when I called the dealership, the car had once again reset itself. The dealer brushed me off, said the cars are so computerized that if they couldn't replicate it they couldn't fix it and said they were backed up on appointments. The 3rd time, the car stopped accelerating on the beltway as I was taking my exit home, almost got rear ended, as I was pulling off the exit and trying to pull over the car started producing white smoke and the smell of gas, the engine control system (1st time of these 3 instances) alerted to shut the car down. The gear shift would not work properly while trying to shut it off. It massively leaked gas out of the vehicle and into the oil/ oil filter. While broken down, multiple cars almost ran into it as it had shut down after a major intersection. The car almost exploded/ caught fire. It was towed to an autobody shop to be inspected as I did not trust the dealership. No repairs were made. Only an oil change and new oil filter. There was a random misfire code. But ran normally once reset. There was no damage that he inspected and called it a Lemon. The dealer has the car, and has yet to diagnose it or give me a loaner. All regular maintenance performed and all system checks have come back normal up to this point.

This Tucson Limited has 3500 miles on it from purchase last September - 2022. Less than 1/2 mile from home and accelerating to about 35mph the engine lost power where speed reduced to about 20mph, acted like air intake was being choked. Did not see any caution lights on the dash. I coasted for 30 feet - luckily the street had no traffic - and the engine began to operate normally. I continued traveling about 2 miles and it happened again but briefly - still on town roads, continued driving and it happened once again climbing a hill. Made it part way up and power came back. Continued driving to destination another 2 miles, parked the car for about 45 minutes, came back, car started normally, drove home without incident. If this occurred on a busy road or highway I'm sure the trip would have ended in an accident. I believe this is a dangerous fault. Car is in for service now and they say the ECU was updated. Hope that corrected the problem as my wife refuses to drive it without some confidence level improvement.

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 turned right into my driveway at a slow speed. As I went onto the driveway, the car surged forward. To avoid driving into the garage door, I turned to the left to drive along the side of my house thinking I would be able to stop it. I kept hitting the break but the car kept going. When the vehicle did not stop, I steered to the right because I thought it could be possible that my neighbor's dog could be in the adjacent yard (to the left of my house) The ground between the houses is pitched down (to the left) towards my house and I side-swiped the back half of the side of my house. Although applying the break, my car continued after sideswiping the side of my house with the front right side of my car and went into the house behind my house causing damage to that house. My car stopped when it went into the house behind my house.

Without any warning indicator my 2022 Hyundai Tucson (11850 miles on car) stalled on the road. I received an alert on my phone from Hyundai, after the car shut down that there was a system failure. Car was towed to Pugi Hyundai dealership (where I purchased in new in Jan. 2022) and after several days I was advised the following: Cause: P0303 Cylinder #3 misfire active. Hyundai technical service Bulletin 23-FL-002H-1 addressed concern. 20DA14R1 Replace 1 GDI fuel injector which includes ((1) injector assey-fuel, (3) combustion seal ring, (1) pipe-high pressure, (4 ) k-Bolt. The dealership and Hyundai Corp. state that until the vehicle breaks down they aren't able to replace the KNOWN defective parts. Therefore, I am left driving a vehicle that WITHOUT warning can stall on the road which is a MAJOR safety risk!!!! This is absolutely not acceptable. This should be a recall! The dealership stated they can replace the remailing 3 fuel injectors for $799 pre-tax. I asked what batch of fuel injectors are they using and the Service Manager stated the new and improved. The old batch was discarded!!!! How is this legal"????"

HeV and engine light came on while car was in motion and immediately lost power/decelerated, causing traffic hazzard to other potential drivers due to sudden and unexpected change in speed and inability to move car out of road. There were no prior warnings. Car is in shop and available for inspection.

- Arlington, VA, USA

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.

On Friday 05.26.2023 I was driving on the highway and lost all acceleration power to the vehicle and was almost rear ended by a semi. Iwas able to pull off the road but had no power of more than 2 MPH to do so. No warning lights came on, no engine error codes. I had the vehicle towed to the dealership pending review. I have only 1,355 miles on the vehicle. I am afraid to drive this car.

While driving on the freeway, suddenly lost power while driving 60 mph and was unable to accelerate. Almost avoided an accident, while trying to merge to the shoulder of the road, while the car just puttering. While on the shoulder, the check engine light came on. Unable to drive and had to get towed.

- Cambria Heights, NY, USA

The car slowed down so I tried stepping on the gas pedal and noticed it wasn-??t working, then I tried stepping on the brake pedal and it didn-??t work neither. The car slowed down and called it to get towed.

Attempting to enter I-295 South in Portland, ME at Exit 7 on March 18, 2023. We were in our 2022 Hyundai Tucson Hybrid Limited with approximately 6,000 miles. I tried to accelerate from the ramp to merge into traffic. The vehicle would not accelerate at all. I made several attempts to accelerate and nothing would happen. Pulled into the breakdown lane while applying pressure to the accelerator but it would not accelerate. The vehicle was in EV (electric vehicle) mode. After approximately 1 minute the vehicle did accelerate. No further problems that day. We called the dealership immediately and left a message regarding the incident. On Monday March 20th We followed up with the dealership and scheduled an appointment for the next day On the 21st of March We dropped the vehicle at the dealership. We picked it up at the end of the day and they told us they installed a software update TSB 23-EE-002H to repair the issue.

twice when my car shifted from second to third gear i lost throttle response and the engine went to idle speed. when i shut the vehicle off and restarted it worked

- Millsboro, DE, USA

The car completely stalled while in the middle of driving. I was on the interstate and was unable to go at appropriate speed, making it dangerous for other drivers. This is the second time that this has happened. The first time, the dealerships said that it was a faulty fuel injector, and replaced it. However, 2 months later, the same problem occurred again. Because I wasn't in an accident, the car was not inspected by anyone other than the dealer. I did not receive any warning lights or symptoms.

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.

With approximately 6552 miles on the car, 7 months after I bought it new, the Vehicle sputtered and shut off. The GDI pump was replaced. It has not runnright since. It sputters, it does not respond appropriately when the accelerator is pressed, it went into limp mode and would not go more than 35 mph. It did not throw and engine code when this happened. This is a huge problem in itself. I could be out of oil and it potentially will not throw a code or warning. When the dealer had it for 45 days they drove it approximately 100 mile and could not duplicate. It is a serious danger to my life and I refuse to drive it. I had it towed and it now sits in my driveway will the lemon law case is processing
