What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 1,677 complaints with NHTSA since 2015. 1,179 of them name Power Train, 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 2019 Jeep Cherokee, the 310 owners who gave an odometer reading for Power Train reported it at a median of 52,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The car stalls while driving for no apparent reason. The engine turns off and there is no power on the dashboard. This will happen regardless of oil levels, even though the car has always had the proper oil level. It takes about 5 minutes to turn on again when you are in the middle of the street/freeway with traffic behind.

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep 1806523 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 1806523 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 1806523 cover?
The manufacturer filed it against 1 model year: 2019 Jeep Cherokee. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
