general problems of the 2023 Hyundai Palisade - part 2

Within the first month after the purchase in late August 2022, the car would shake when turning onto road. Depressing the gas peddle did nothing. The speedometer would not go over 20 mph, but the car was not moving, only coasting. The rpm would jump to over 3000 rpm. Again, the car is not moving, only coasting. There was no engine noise, only the sound of the gas pedal hitting the floor. Subsequent pumps of the gas peddle did nothing, but about 20-30 seconds of this behavior, the car would start to kick into drive. There were no instrument panel alarms, warnings, or lights. By October 2022, the problem occurred every time I drove the car first thing after it had been off for several hours. For the rest of fall, winter, and spring with temperatures under 30 degrees, this problem would occur. I have to use one of 2 highways to leave my home. Both highways were dangerous for this problem. I had to wait for no traffic as far as I could see, but with coasting speeds and no control, it didn't take long for traffic to catch up. In some cases, after a turn onto a highway or 2-lane busy street, there was no where to coast off the road. I used hazard lights a lot, but it was clear that the danger was significant. The third cold weather season is coming soon. The problem will most certainly occur has it has every year since we purchased it. The problem seems to occur at intersections where this is a greater than 5% grade. It does not occur on a flat grade. The dealer tells us that unless their diagnostic equipment from Hyundai USA cannot detect a problem, then they cannot do a repair. Even though the technicians witnessed the problem away from the dealership, they cannot make it fail at the dealership. They want to keep the car for days or weeks, but we've been through this and I turned them down. Hyundai USA keeps telling me to file a claim, which I did. To date, I have not received any further correspondence since I filed it.

While driving on the highway, a safety alert appeared saying, “engine is off. Shift to p or n. ” the car then turned off on its own, and had to be restarted. The “start/stop” ignition button, nor the shift buttons, were pressed before the alert went off. Essentially, the engine stalled and the car stopped on its own while driving.
