On June 1 2021 I delivered my 2017 Dodge Durango to the Carson City Dodge dealer because of a 'ticking' sound coming from the engine. It turned out to be a leaking head gasket. We purchased the Durango at Reno Dodge in Reno Nevada by ordering it in 2016. It has been one of the best cars we have ever had. The Service department called to say that the RT had a leaking head gasket that had to be replaced. I was surprised so I researched it on line and was surprised to find that the exact same sound and problem was being reported in 2016. We had purchased the Dodge Lifetime Warranty so we weren't too concerned. The service agent said that he had submitted the claim to Dodge which required a Dodge company representative to approve the claim before Carson Dodge could begin work. He also said that he could not locate a head gasket which would prevent the repair and he had no idea when he could get the gasket. We are surprised that we were not notified by Dodge of this problem since it has been reported on the internet as being a problem in 2016. It's been a week and we haven't heard anything and we are getting concerned as we have a vacation planned for the first of July and will need our Durango.
