NHTSA Complaint #11525100 — 2015 VOLKSWAGEN GOLF

Over the last two months, I've had over 30 incidences where the car will either randomly shift extremely hard into a gear or will hesitate, stutter, lose power while accelerating. Some of the shifts have been so hard that they've thrown me forward. Some of the losses of power are extremely dangerous as I'm accelerating at highway speeds. I have a full log of at least 30 of these incidents (and detailed as best I could) and they are attached. I picked May 11th because that was the hardest shift/loss of power which caused me the greatest harm. I've been able to reproduce the errors in drive, sport, and Tiptronic mode. The errors occur in all gears, but are most common in 2nd and 3rd (although the higher gears are involved as well), which leads me to believe it's not the transmission, yet the mechatronics unit or something outside of the transmission and engine itself. The troubling issue here is that the car is recording absolutely zero fault codes for diagnosis; that is, the car is shifting, stuttering, hesitating randomly and erratically and no diagnostics are being provided to resolve the issue. Technicians are able to guess what the issue is, but cannot give a guarantee what the problem is without the fault codes. This is the greatest safety concern, but luckily no crashes so far. I was interested to learn that there was a recall on the same model by the Australian government related to the pressure accumulator and I'd like to see if this could be the issue, since I'm experiencing the same symptoms as those described in the recall: https://www.vehiclerecalls.gov.au/recalls/rec-005369. The contact stated that the loss of power issue still persists. The contact stated the issue is a faulty crank trigger.
