My 2017 started to shudder…
My 2017 started to shudder around 30,000 miles. Dealership flushed and filled with new fluid under warranty. No shudder until around 100,000 miles when it started shuddering again. This time I just added lube guard instant shudder fix myself and its worked for 10,000 miles. Just recently the rear main seal and starter have both failed. Hope you have better luck.
