Please also check out the statistics and reliability analysis of the 2018 Jeep Grand Cherokee based on all problems reported for the 2018 Grand Cherokee.
After a cold start (even in warm weather), when shifting from 'park' to 'drive' the transmission shudders momentarily and shakes the whole vehicle. It does not do this when the engine is up to normal operating temp, or if you wait 10-15 seconds before putting it into drive. I have not had this problem with any other vehicles I've owned.
