What it saysThis Technical Information Notice informs dealers that MMNA is investigating reports of abnormal noise/vibration from the rear differential assembly. NHTSA’s full summary ↓
Mitsubishi filed this with NHTSA as a service bulletin dated Nov 4, 2025, received Dec 6, 2025, about the power train. It names 2 model years (2024–2025). 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 46 complaints with NHTSA since 2015. 5 of them name 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 on even a slight hill, sometimes the car rolls back if I am not moving forward. For example, if ai am stopped at a red light, the car will roll backwards (instead of not moving or going forward). It’s an automatic transmission so this should not occur. I.e. the transmission is already starting to go out b4 35k miles.
2024 Mitsubishi Outlander · Power Train · filed with NHTSA Feb 15, 2026 · ODI 11718148
My 2025 Mitsubishi Outlander PHEV has experienced recurring, severe powertrain failures causing a dangerous 'PHEV System Fault / Power Reduced' limp mode at highway speeds, dropping instantly from 60+ MPH to severely restricted speeds. This creates an immediate risk of a high-speed rear-end collision.

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 Mitsubishi TIN-25-27-001 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 TIN-25-27-001 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 Mitsubishi warranty extension on file lists the ones Mitsubishi has filed.
Which vehicles does TIN-25-27-001 cover?
The manufacturer filed it against 2 model years: 2025 Mitsubishi Outlander, 2024 Mitsubishi Outlander. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone. The document itself sets the build window: built after 18 Jun 2024 — the build date is on the certification label in the driver’s door jamb.
