What owners reported
Source: NHTSA complaint databaseOwners of the 1 model year this bulletin names have filed 496 complaints with NHTSA since 2015. 275 of them name Electrical System, Power Train — 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 2022 Jeep Grand Cherokee, the 18 owners who gave an odometer reading for Electrical System reported it at a median of 20,900 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Randomly, and without warning, the instruments, gauges, and displays will switch into a language I do not speak or understand (Italian). Coinciding with the switch to Italian language, cluster and radio display settings revert back to default settings, auto door locks and paddle shifter becomes inoperative (with no menu to enable)…

Common questions
Source: NHTSA, 49 CFR 579.5Is Jeep 2101623 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 2101623 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 2101623 cover?
The manufacturer filed it against 1 model year: 2022 Jeep Grand Cherokee. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
