2022 Hyundai Tucson

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.

-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.

The contact owns a 2022 Hyundai Tucson. The contact stated while driving at an undisclosed speed, the vehicle stalled. Additionally, an unknown warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 12,000.

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.

My vehicle wouldn't start.3 warning indicator lights came on. I had just driven my car 4 hours ago and was going to delivery a cake. My car was parked in my garage. I pushed starter but vehicle wouldn't start. Had to push starter several times before indicator lights would shout off. Had to have vehicle towed to dealership on 7/9/23

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.
