Stellantis bulletin 9100337

What it says"PUMP WATER For 2016-2024MY 3.6L Pentastar Upgrade with suspected coolant leak. NHTSA’s full summary ↓

Stellantis filed this with NHTSA as a service bulletin dated May 2, 2024, received May 17, 2024, about the engine. It names 49 model years across Jeep, Ram, Dodge and Chrysler (2016–2024). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

One page for every brand it was filed under. Each brand’s bulletins: Jeep · Ram · Dodge · Chrysler.

What the bulletin says

Source: NHTSA's summary of the manufacturer's communication
Engine 3.6L Pentastar “"PUMP WATER For 2016-2024MY 3.6L Pentastar Upgrade with suspected coolant leak.”

What it applies to, as NHTSA’s summary states it — build dates and equipment as the manufacturer filed them. The dealer checks the VIN and the build date on the door jamb; a vehicle outside the window is not covered by this bulletin.

"PUMP WATER For 2016-2024MY 3.6L Pentastar Upgrade with suspected coolant leak. PRIOR TO PERFORMING ANY WATER PUMP REPLACEMENT, PROCEED WITH INSPECTION INSTRUCTIONS FROM THE LATEST VERSION OF STAR ONLINE PUBLICATION S2307000002. Please submit pictures of the leak area thru the DIDI process outlined in the STAR Online document. NOTE: Some coolant residue may be found at the water pump weep hole plug area which may be normal, but coolant should not be dripping from this location. If unsure about, use the Pressurized Coolant System Inspection process as found in the Dealer Connect Cooling Diagnosis and Testing Procedures."

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 database

Owners of the 49 model years this bulletin names have filed 19,709 complaints with NHTSA since 2015. 4,877 of them name Engine — 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 2017 Chrysler Pacifica, the 268 owners who gave an odometer reading for Engine reported it at a median of 20,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

While driving at highway speed the vehicle flashed a vehicle and I’ll shut down sign. A red turtle flashed and the vehicle began to decelerate. Had to pull over to a less than safe sand shoulder. Had highway speed traffic directly behind me. Dealership pulled codes related to the transmission. No previous issues or sign thereof. 25k miles

2023 Chrysler Pacifica · Engine · filed with NHTSA Apr 3, 2025 · ODI 11652655

While driving on the highway, the engine overheating light came on, the car seemed to be losing power, and I pulled over and was then towed to the dealership. My safety was put at risk as I could have been hit as the car was slowing down in fast traffic; it also was extremely cold (about 5 degrees F) while I waited for the tow truck.

2022 Dodge Durango · Engine · filed with NHTSA Mar 23, 2025 · ODI 11649967

As I was pulling up to a red light, the vehicle threw itself into park and completely stopped and would not move. I was unable to put gear into drive. Thankfully, I was not going at full speed. After a couple minutes, I was able to put my foot on brake to restart the car. At this point, the engine and battery light were on as well.

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 Stellantis 9100337 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 9100337 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 9100337 cover?

The manufacturer filed it against 49 model years across 4 brands (Jeep, Ram, Dodge and Chrysler): 2024 Chrysler Pacifica, 2023 Chrysler Pacifica, 2022 Chrysler Pacifica, 2021 Chrysler Pacifica, 2020 Chrysler Pacifica, 2019 Chrysler Pacifica and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
