2022 Hyundai Tucson PLUG-IN Hybrid

While accelerating on an on ramp leading to the interstate, the 2022 Hyundai Tucson PHEV Limited was in the Smart Drive Mode and the vehicle was in Electric Mode only being powered by the electric motor. I noticed that the vehicle was struggling to accelerate to the interstate speed of 70 MPH, I pressed the accelerator further in order to gain more speed to safely merge onto the interstate. With the accelerator pushed all the way, the engine eventually turned on after 5-7 seconds assisting the vehicle to reach the speed of 70 MPH. Once on the interstate, I set the cruise control to 70 MPH but the vehicle was not able to maintain that speed. The speed of the Tucson started to drop suddenly and I then began to make my way to the right shoulder of the interstate. During the process of moving to the right shoulder, I did notice that the Power Gauge on the instrument cluster was maxed out, the vehicles engine was running at at very high revs, but I was never able to get more speed out of the vehicle. The vehicle was slowed to 40-45 MPH by the time I was able to reach the shoulder due to traffic. Once on the shoulder and out of the 3 lane, 70 MPH traffic, I was able to power down the vehicle and restart the vehicle with no issues. I then put the vehicle in drive and signaled to the left in order to merge back into traffic. I accelerated briskly to merge with the 70 MPH traffic and the vehicle did operate as normal. The vehicle began to move under EV power and the engine did turn on to begin assisting in moving the vehicle up to speed. The vehicle operated normally for the remainder of my drive, approximately 3-4 miles. During this event, the vehicle never did display any warning lights or messages on the instrument panel or the center screen. No warning tones or chimes were given either. The high voltage battery was at an approximately 68% state of charge and the fuel tank was approximately half full.

purchased new 2022 hyundai tucson plug in hybrid in december 2021. In April 2022 the vehicle with 5500 miles experienced loud transmission bangs and lost ability to change gears. vehicle then stuck in neutral in driveway unable to select drive or reverse. had vehicle towed to dealership. once at dealer, mechanic unable to replicate problem but was able to pull up trouble code history. mechanic was told by hyundai corporate technicians to reset the transmission to fix problem. Fast forward to July 21, 2022, vehicle started to flash several warning indicators on dash including forward collision assist, no left turn signal and check engine light and transmission once again stuck in gear unable to select drive or reverse( approx. 9000miles) Upon disconnect of vehicle battery was able to get vehicle into gear to remove from garage. All warning lights remained on vehicle for 4 weeks before I was able to get a service appointment to fix problem. at dealer on august 16, 2022, check engine light reset prior to arrival, once again dealer unable to replicate problem and was told to return if vehicle exhibited issue again. August 22, 2022, upon leaving driveway and while in drive the vehicle just stopped in middle of roadway. once again stuck in neutral and all warning lights once again lit up. vehicle pushed to side of road to get out of roadway. upon starting the vehicle several times and turning off vehicle, finally was able to switch into gear. Roadside assistance was called to tow vehicle to dealership, where once again no loaner cars were available. The vehicle has exhibited lack of power on several occasions as well. specifically when going up a graded road. on one occasion vehicle would not go over 10mph. The fact that the vehicle died in the middle of the road while under operation is a huge safety concern as if i were on a freeway or expressway and it just stopped it could have been catastrophic. please look into this issue before someone gets seriously hurt.
