weak plastic filler neck snaps off when filling with fuel weak plastic filler neck snaps off when filling with fuel

I've come to learn this part was redesigned 3 times during 2014. The manufacturer has clearly identified the original design was defective and made several attempts to rectify it. My understanding is from mid-2014 onward the replacement was a complete new fuel filler system. For individuals such as myself, who are unfortunate enough to have one of the earlier defective systems, Jeep's solution is for the customer to have to pay for a complete new system costing $200 plus 2 hours labor @$250 hr - that's $700 for the customer to pay for a complete new fuel system because a $50 plastic neck was faulty, defective, weak and thus was discontinued.

This part should absolutely be covered on an extended warranty . Note to Fiat group : you know it's a problem, hence you redesigned it 3 times in 12 months so have the decency to fix it for your customers.

The fuel filler plastic piece broke out and the dealer wanted nearly $1000 to fix it. It is part of the solution control system and should be fixed under that warranty but everyone at the local dealership plays dumb when I bring it up. First time they ever heard of it!. Right. Look online fellas.

My last Jeep product.

Update from Jan 11, 2018: "solution" should read Pollution Control System

weak plastic filler neck snaps off when filling with fuel

Capless fuel neck is made of ABS plastic that cannot take lateral stress, Careless gas attendant can easily snap off neck. Have seen this at gas stations ( one station had a collection of said parts that they found on the gas nozzle after the customer drove off). I had been warned of this by another station attendant and was watching and actually saw it happen on my car. Jeep should be ashamed of this problem. Not fixed yet but estimate is $500 to fix because of amount of labor to replace this $80 part.
