What owners reported

Source: NHTSA complaint database

Owners of the 1 model year this bulletin names have filed 964 complaints with NHTSA since 2015. 463 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 2021 Jeep Wrangler, the 34 owners who gave an odometer reading for Electrical System reported it at a median of 29,400 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

The contact owns a 2021 Jeep Wrangler 4XE. The contact stated that while driving at 75 MPH, the vehicle lost motive power rapidly and unexpectedly. The contact pulled over to the shoulder before the vehicle stalled. The contact returned to the contact's residence safely, and the vehicle was towed to the dealer the following day.

Only 500 miles on vehicle, went off-roading for the first time and within a short time after climbing a steep hill, smoke came from under vehicle and clutch went to floor and stayed. Turned Jeep off, pumped clutch which seemed fine but smoke continued for a minute.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions

Source: NHTSA, 49 CFR 579.5

Is Jeep 0804723 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 0804723 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 0804723 cover?

The manufacturer filed it against 1 model year: 2021 Jeep Wrangler. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
