Read by machine from the document NHTSA serves (2 pages), read Sep 29, 2026. A part number is shown only where it matches Dodge’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 1 model year this bulletin names have filed 58 complaints with NHTSA since 2015. 19 of them name Engine, 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.
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
The transmission dropped after being stopped at a stop light and lightly accelerating. When this happened the vehicle dropped to neutral. After pulling over it did go into first gear but that’s it. When in reverse it moves a foot then goes back in to neutral

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 579.5Is Dodge 18-034-26 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 18-034-26 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.
Which vehicles does 18-034-26 cover?
The manufacturer filed it against 1 model year: 2022 Dodge Durango. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
