Owner report 11418216 · 2021-05-23 (May 23, 2021)
Starting March 29, 2021 fuel cell failure when pressing the accelerator, started out as an intermittent failure. Over the period of two weeks while waiting for an appointment to get the vehicle in for repair the problem increased in infrequency. When the vehicle was delivered to the dealership for repair any attempt to accelerate would cause the vehicles fuel cell to shut down and fail. As of May 23, 2021 I have requested and dealership has not released any service documents. The dealership still has possession of the vehicle.

Owner report 11452656 · 2022-02-18 (February 18, 2022)
The city I live is located on top of a hill/low mountain. When I drive uphill by following speed limits to my home the car often can't keep recommended speed (45 mph). The speed drops significantly(can go even 25 mph) and unpredictable. At the beginning I believe the car was able to keep the speed but it slowly started losing the power. The risk is that a vehicle behind might not expect such behavior from my car and also changing lanes is tricky because it can't accelerate and it moves slower than other cars on the road. I've contacted dealer…
