On 3 occasions over my 18-month ownership of this certified pre-owned Hyundai 2022 Tucson, the vehicle surged suddenly forward WITH BRAKE APPLIED at creeping (parking) speeds of 3-4 mph. No warning lamps were observed. On the most recent (3rd) occasion, a crash over a sidewalk and into a storefront caused $10,000 damage. No pedestrians were harmed, no airbags deployed and neither passenger was harmed. The service department is "unable to duplicate" the surging behavior and declares the car mechanically "safe to drive."

I am submitting this complaint regarding my 2022 Hyundai Tucson equipped with the 2.5L engine. The vehicle has experienced multiple incidents of severe engine misfiring while driving. During these events, the engine begins to shake violently, the entire vehicle vibrates, and engine power is significantly reduced. The vehicle becomes unable to accelerate normally, creating a serious safety hazard, especially when driving on highways or in traffic. The malfunction has occurred several times. Diagnostic trouble codes P0302 and P0303 have been recorded, indicating cylinder misfires. In some cases, turning the engine off and restarting it temporarily restores normal operation. On other occasions, adding fuel system cleaner appeared to temporarily improve the condition. However, the problem eventually returns. Because the condition is intermittent, the Hyundai dealership has been unable to reproduce the failure during inspection and therefore has not performed a repair under warranty. Despite multiple visits, the root cause remains unidentified. I am concerned that the sudden loss of power and severe engine vibration could result in an accident if the vehicle is unable to maintain speed or accelerate while traveling at highway speeds. This issue has significantly affected the safe operation of the vehicle. I request that this matter be investigated, as it appears to be a recurring safety-related defect.

The car keeps loosing power when it is over 90 degrees outside. On my way to work in the morning it has plenty of power but on my way home around 5 or 6 PM it struggles to gain speed. I’ve already had all the fuel injectors replaced so I don’t think it is related to that. It mainly happens when I slow down but not to a full stop around 20 MPH. Then it struggles to accelerate after that.

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.
