Accelerator Pedal Sensor Problems of Volkswagen GTI

This has happened several times beginning in March, 2018. Epc light comes on (seemingly) randomly. Occasionally, check engine light/service engine now warning will also come on. Sometimes they all shut off after letting the car sit overnight. Epc light comes on sometimes when we turn the car on and sometimes while driving. We have had three incidents where we try to get onto the interstate (70mph) and can't get above approx 40mph. I've almost been rear-ended twice because of this. On another occasion, I couldn't get the turbo to kick in. So, driving at 65mph again on the interstate, I couldn't get up hills and would end up at approx 55pmh by the time I reached level ground. Again, cars swerving to get around me. My husband has had a complete loss of control of acceleration and had to coast over onto the side of the road. I had it happen once at a stop light, taking a long time and a lot of coaxing of the accelerator pedal just to get up to 40mph. These all happened on straight stretches of road and normal weather conditions. Restarting the car may or may not reset the acceleration issue and the epc light. Computer scan from vw dealer showed throttle body sensor, so we replaced that with same symptoms after a couple of days. Then, computer says it's accelerator pedal sensor. Replaced also with same results. Replaced spark plugs, air flow sensor, cleaned other sensors, still the same. This is very dangerous. I see in forums that we are not the only ones. It is expensive to keep chasing the problem but lives are at risk. Someone is going to get seriously hurt because their limp cars can't keep up with traffic. Vw seems stumped. The only solution I see is getting rid of this dangerous car but I'd hate to pass that risk onto another person either! plus, dealers pay very little to take this off of our hands for the same reasons. Please help!!!!.
