Catastrophic "Critical" coolant system failure. Resulting in vehicle completely disabled on the roadside. Police and Fire Dept. responded. I have been communicating with Jaguar North Scottsdale and Jaguar Land Rover North America LLC for resolution. The Coolant System defective parts were identified in 2017, newly designed "y" pipe and outlet pipes, single extruded pipes, have been available since 2018. (See Attached Technical Bulletin). Jaguar has not offered these repairs under warranty or recall to their vehicle owners, rather, shifting the blame on the consumer. JLR has had knowledge and remedy to their disposal and have done nothing to rectify the poorly designed Coolant System, which under many circumstances has also created catastrophic engine failure, warped heads and engine block. The Service Manager at Jaguar North Scottsdale admitted that the, "coolant system was poorly designed at best".Jaguar Forums on the internet are filled with numerous complaints about this issue; this could obviously be rectified through a recall, as evidenced by the fact that JLR Service Departments have available for installation, the redesigned parts. There were no gauges or impending warning messages prior to the "critical alert" message which displayed simultaneously with steam pouring from underneath the hood and exiting the exhaust system.

Gear selector sticks at start-up and doesn't raise up to engage the car out of park. Have turn off the vehicle and re-start for the gear selector to raise. Trunk hatch will sometimes raise only part-way. Interior light panels for trunk button do not illuminate.
