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.

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.

Sudden loss of power and speed on freeway traveling at 75 mph almost caused a rear end collision by tailgating semi. Pulled over onto shoulder with engine shaking and bucking and luckily limped off nearby exit. Engine control system error popped up. Engine would barely start and stall quickly and eventually would not restart at all. This is the cars second sudden power loss and engine problem at speed since. Not acceptable for a brand new car.

First occurrence was on 6JAN23 when the vehicle was being driven and it suddenly and quickly reduced speed to under 30mph. Vehicle then continued to go up in RPMS to nearly 4,000 but the car felt like the transmission was not engaged and driving in neutral then would engage and disengage, causing fluctuations in speed, but never above 30-35 mph. This continued to happen until we could pull over safely and turn off the vehicle and restart. No engine light or warnings illuminated. Vehicle was taken to the dealer for diagnostic and nothing was found. Second occurrence was 01ARP23, with exactly the same results. In doing some research I have found several other complaints with this issue. This is a serious accident waiting to happen.

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.
