Simply put, all RV manufacturers produce rigs that have flaws, some are more glaring than others while some flaws remain hidden an unknown to the owner.
Jayco has a decent quality build on most of their rigs, but they are huge and are pumping them out at a rate very few RV manufacturers can attest to.
Every new RV has a 1 year warranty and a few have 2 years, Jayco has long provided a 2 year warranty that under most circumstance they have covered.
Appliances among other items contained within an RV have their own warranties and those issues are normally addressed by the product manufacturer.
Whether this story and the degree of actuality is factual, reaching out to Jayco directly, if given the opportunity they will typically take care of you.
