My 2019 XC60 T5 AWD Inscription has 3,400 miles on it. It is back in the shop for the second time in a month for an ECS problem. The first time the ECS/Check Engine light came on, in March, the dealer kept it for a day and told me that they had replaced the fuel filler pipe (problem on multiple recent XC60s) and updated the vehicle's software. 3 weeks later, the ECS light was back on. Took a week to get a service appointment with a loaner. They tell me today that the vehicle has "fault codes for the evap lines at the engine for the ECS system. 2 lines require replacement, and the parts have to be special ordered, which will take a week." Dealer also told me (because I asked) that mine is the 3rd XC60 in a week with this same issue. "There's a problem with the way the current evap lines are routed and the emissions system in the car does not agree. Volvo has designed a very sensitive emissions system on these vehicles." Apparently so! This is not a good start to first four months of ownership, (and I'm even giving them hall pass on the rear liftgate strut recall/replacement).
Any thoughts on this from those more mechanical than I?
