Jaguar XJ engine failure with random hesitations and shutdown after driving, warranty dispute ongoing on Jaguar XJ

Some Jaguar XJ owners report experiencing engine issues such as misfiring, noticeable power loss, difficulty starting, and stalling after starting. These problems can lead to random hesitations and shutdowns, complicating the driving experience. Additionally, owners with ongoing warranty disputes emphasize the importance of understanding warranty terms and what repairs are covered, as some repairs may still be addressed under factory warranty. However, navigating these disputes can be challenging and costly, prompting some owners to document all interactions with the manufacturer or dealer and seek legal advice if necessary. Common problems reported include engine misfires and stalling, and even if the warranty has expired, some repairs may still be addressed at no cost by Jaguar. To tackle these engine issues effectively, many owners seek assistance from Jaguar specialists or reputable repair shops with expertise in Jaguar vehicles. Some have found that technical solutions, such as cleaning dirty throttle valves, can resolve specific problems like RPM fluctuations and stalling at idle.
