2016 Jaguar F-TYPE

I own a 2016 Jaguar F-Type R. Some of these cars have an inherent manufacturing flaw with the coating on the trim pieces. From my research I discovered that this is a wide ranging problem for their vehicles in geographic locations that are consistently hot. Jaguar Land Rover North America is well aware of this problem. On 1/24/20 I brought my vehicle in for service. On this service call the vehicle was under warranty. I pointed out the issue with the right side vent trim piece, the worst of the deteriorating parts. The coating was deteriorating from the heat. In these cases they start to peel or become sticky like rubber cement. The other trim pieces also needed to be replaced. They replaced the old flawed part with a new flawed part. For this reason I thought it useless to have the other failing parts replaced, as they would eventually deteriorate. I discovered that new replacement parts were available, that could have been replaced under warranty, that do not have the deterioration issue. On 11/23/20 I contacted JLR corp and requested they replace the parts as an under warranty issue, with the upgraded components, which they could have under warranty. They denied this because the vehicle was now past warranty. After months of negotiation they agreed to give me an 80% discount on the upgraded parts. This however still cost me $967.80. This does not seem ethical or fair to me. They were notified of this issue while still under warranty. Furthermore, I wonder If this should have been a recall issue. Either way, I am requesting a refund.

WHEN CHANGING LANES @ APP. 45MPH, THE CAR INITIALLY FELT AS IF IT WOULD ROLL OVER. THE CAR THEN SWERVED RIGHT AND LEFT , NEARLY PUSHING ME INTO THE TRAFFIC IN THE NEXT LANE. STEERING WAS VERY DIFFICULT TO CONTROL, REQUIRING MY FULL STRENGTH. AFTER A FEW MINUTES, THE CAR STRAIGHTENED AND STEERING EFFORT RETURNED TO NORMAL.THIS OCCURRED ON A SMOOTH, 4-LANE ROAD WHICH WAS DRY. JAGUAR SERVICE PERSONNEL WERE AWARE OF SIMILAR ISSUES BUT COLD NOT IDENTIFY A CAUSE.
