Do you know if there is a problem with the new Jaguar XE petrol Ingenium engine when coupled with the auto gearbox? Our new model lurches when going down through the lower gears. At first, the dealer agreed there was a fault and attempted a repair, but then said "all the petrol ones do that" - as if that makes it alright. We rejected the car within 30 days, which the head of the business initially verbally agreed to - but after the 30 days he said Jaguar must agree as they will not allow a rejection without Jaguar’s agreement. They will not put anything in writing.
