It is.I went to the dealer for final paperwork intending to purchase the Zeigler 7 yr/unlimited warranty on my own. After hearing about the "dealers warranty" I told them I planned on getting the one from Zeigler. They matched the discounted price so it was added into the purchase. I believe the Zeigler plan is the real deal Mopar factory warranty.
You can buy a Mopar ESP from any dealership. Some sell them for (a lot) less margin than others.
As long as it a Mopar ESP (Extended Service Plan aka Extended Warranty) then it is the "real deal".
Don't be fooled. Dealerships will usually try to offer (or convince you to get) different 3rd party warranties that are not Mopar. They make more money selling those (upwards of $1000 per policy sold, if not more) and will push those harder than a factory plan.
They aren't much different as far as coverage but can be very different in execution:
1. Mopar will not go out of business. If anything, policy costs will change year-to-year based on how much warranty money Stellantis has payed out to dealerships (fun fact - part of the MSRP price of the vehicle takes into account how much money the company has spent on basic warranty work for the previous year).
2. It's attached to my VIN and is accepted at any RAM service department.
3. When the dealership tells me it's covered, it's covered. When the work is done I pay my deductible and take my truck home. I don't have to worry about if/when the dealership is going to get paid so I can get my truck back.
I'm sure others have had good luck with 3rd party policies (Chris Berman and Ice-T have way nicer vehicles than I do), including some offered by auto insurance companies, but I like knowing mine is accepted wherever I take my truck and there's no additional waiting for approval after the service department says they'll fix it.
