Pre 2020 discovery sport chain rattle potential failure. This should be a recall as the number of repairs taking place around the country suggest that it a fault in the design also I believe the same engine is fitted in the Jag that's having a recall as this is a costly repair land rover UK should pick up the cost.
I've emailed customer care at
clientcare@jaguarlandrover.com
So let's all let them know what's happening with this model it's the only way to get a recall.
