It names 58 model years across Jeep, Ram, Dodge and Chrysler (2018–2021).

Quoting the number at a service desk can save a diagnosis.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 52 model years this bulletin names have filed 22,519 complaints with NHTSA since 2015. 5,819 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2018 Chrysler Pacifica, the 176 owners who gave an odometer reading for Electrical System reported it at a median of 13,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
While traveling on the highway at approx. 70mph at night the vehicle shutdown completely resulting in the loss of throttle, power steering and lights. This is an safety issue that can cause death or serious bodily harm to the driver and other drivers along a motorway as the vehicle is no longer able to be seen in low light situations and…

Common questions
Source: NHTSA, 49 CFR 579.5Is Stellantis ReferenceZD7 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the ReferenceZD7 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every Stellantis warranty extension on file lists the ones Stellantis has filed.
Which vehicles does ReferenceZD7 cover?
The manufacturer filed it against 58 model years across 4 brands (Jeep, Ram, Dodge and Chrysler): 2021 Chrysler 300, 2020 Chrysler 300, 2019 Chrysler 300, 2018 Chrysler 300, 2021 Chrysler Pacifica, 2020 Chrysler Pacifica and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
