Mitsubishi bulletin TIN-21-00-004
What it saysThis Technical Information Notice was sent to dealers informing them Owner Manuals (OM) are now available electronically beginning with Model Year 2015. NHTSA’s full summary ↓
Mitsubishi filed this with NHTSA as a service bulletin dated Aug 24, 2021, received Sep 9, 2021, about the electrical system. It names 23 model years (2016–2022). 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.

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.

Driving home with no other cars around the forward collision warning goes off for no reason losing power and slowing down on it's own. This has been an ongoing situation since the car was new, I've made numerous attempts to have my local dealership look into this situation and all they tell me is to take video when it happens

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-21-00-004 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-21-00-004 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-21-00-004 cover?
The manufacturer filed it against 23 model years: 2022 Mitsubishi Eclipse Cross, 2020 Mitsubishi Eclipse Cross, 2019 Mitsubishi Eclipse Cross, 2018 Mitsubishi Eclipse Cross, 2017 Mitsubishi Lancer, 2016 Mitsubishi Lancer and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
