Please also check out the statistics and reliability analysis of the 2021 Jeep Grand Cherokee based on all problems reported for the 2021 Grand Cherokee.
Vehicle is making a knocking noise when in drive and fully stopped. This occurs after drive the vehicle for about 10 miles, once the engine warms up. I've been told that it was a purge selenoid and it's normal. Was also told it was an egr valve and also advised that it was the air suspension. Meanwhile they have a open star case stating it's the motor mounts. 100s of people are having the same issue on the facebook group I'm in, as well as forums and no one is getting anywhere. Also my radio system is making a hissing noise and the android auto connection is not stable and doesn't stay connected. They currently have no fix for this. My steering wheel is slightly off to the right to go straight. They stated the alignment is good and that it does that because incase the driver falls asleep, it would drive them off the road instead of into oncoming traffic. That's sounds extremely bogus and very dangerous.
