Car lost ability to accelerate and was shuddering for the second time. My personal code reader pulls up codes P0191 and P0303. Engine misfire. Second time since June28,2023. Bought the Hyundai Tucson brand new in December of 2021. First time car lost acceleration and was shuddering on the interstate with my toddler son and pregnant wife stranded. The second time was tonight, October 30th, 2023. I was in the car with my still pregnant wife and toddler son.

While driving vehicle, car lost power and show down on highway. Car would not start. Eventually started and sputtered white smoke and the smell of fuel. Car would only go 2 miles and hour. Took to dealership and they said it was the fuel injector pump. No recall has been issued even though several other Hyundai and Genesis i models have recalls for same issue.

1) Transmission: while driving car jerks. when I-??m accelerating from a stop sign or stop light the wheels kind of feel like they-??re spinning/shaking and driving over gravel when I accelerate, before it actually starts and shifts gears. Car accelerating but not moving. 2) Not safe. Almost hit other cars around and people. 3) Dealer confirmed and replacing with new transmission. 4) No warning signs

While driving the check engine light comes on and the car loses power and starts running very ruff and almost stalls at times. This is the second time this has happen in 3 months, last time they replaced a fuel injector. I look up the problem and it seams to be common problem with the 2022 Hyundai Tucson.

July.2023: Check Engine Light On ; It came as we were driving on the highway. Acceleration was sluggish due to this issue. Error code indicated that 1 of the 4 engine had issues. Escalated the issue to Hyundai Customer Service. Issue was resolved during first week of Aug.2023. Sept.2023 We were driving on the highway and Check Engine Light came once again. It was late at night. The acceleration was sluggish and managed to drive to a nearby hotel. Contacted Hyundai Customer Service. 2 out of 4 cylinder had issues (replace rotor, wiring etc.,). Dropped the car in a Hyundai dealership (Urbana, IL). Rented a rental car to drive back to MI. Given the recurring cylinder issue, Hyundai Customer Service is NOT willing to accept the issue with Engine. 2 out of 4 cylinders had issue. Remaining 2 cylinders may have similar issue. Given the issue, quality of 2022 Hyundai Tucson Engine design and build quality is a MAJOR issue and RISK for customers. Should you be driving in a freeway, acceleration will be sluggish and can cause major accidents.

Since I received my car, within a few couple of months I have noticed that the car would jump forward when changing the RPMs/gears. When I had brought it in for an oil change, I had mentioned it to the service tech and they told me they would run a diagnostic to see if anything would pop up but the likelihood hood it wouldn't show anything. The second time I mentioned it again while I was driving, the car would accelerate faster than normal as though it was on Sports Mode even though it wasn't, and then the car/engine would jump or make the car lunge forward as it was slowing down. They said they would look into it again but nothing was found. a few months later I was driving home on the freeway when my car jumped again, the engine turned off and I was in the middle of the freeway not being able to accelerate but take the speed I was going to move over to the emergency side in order not to get hit by another car. I got it towed into the dealership, they said they would get back to me after a few days and once they found out what happened, they had my car for about 2 weeks. They also wanted me to pay for a fuel system flush and returned the car to me on empty gas which was full when I brought it in. The back passenger window wasn't working either and I had brought that up to their attention saying if I were to bring it back in I would need to pay for a diagnostic to get it fixed. I was upset and brought it into another dealership to get fixed and mentioned again about the car jumping and afraid that I would be left on the side of the road or the engine would turn off again. They couldn't do anything without an engine light to be turned on. I'm afraid of driving my car but why am I paying for something that the dealership cannot fix or know that whatever they did wasn't fixing the problem? I have brought in my car time and time again to get seen or fixed before the major issue happened and now electrical parts of the car are faulty with things turning off randomly.

When I-??m at a dead stop, and start to drive off, there is a jerking at around 13 miles per hour. I believe it is when it is shifting from first into second gear. It happens often, but not all the time. This happened when I first bought my car, and I was told that the car has to get to know me. I thought this was true, because it seemed to have stopped at some point for a while. Now it is doing it again, but more dramatically. The jerking is very obvious. Also there have been about 5 times when the car revs by itself when I am in the 40-??s. I am not pressing heaving on the gas, I am just driving, and it sounds like it slipped out of gear for a second and the car is revving, and then it just goes back to normal.

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.

Engine light is on at 6,000 miles, they fixed but on again a month after repair.

- Woodbridge, VA, USA

The affected part is the engine and/or power train, the engine light constantly stays on. The acceleration decreases and unable to drive over 40 mph. These parts were inspected by two different car mechanics at Hyundai Car dealerships, Alexandria, VA (April May 2023) and Waldorf, MD, (June -July 2023) which they say was the gas cap. After getting a diagnostic the reading was P0 301. On August 22,2023 at 9:30am took the car to mechanical service at Hyundai In Waldorf, MD they concluded it was the gas cap, again, today the engine is on again.

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!

-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.

I got this message on the car screen: check hybrid system!! Last Sunday I was driving when I lost all acceleration and this warning came up and told me to pull over safely

- North Bergen, NJ, USA

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.
