What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationTELEMATICS SERVICE INFORMATION HINT: This bulletin applies to vehicles equipped with a 4G network compatible TCU. TCUs compatible with 3G network only are no longer supported. SERVICE INFORMATION The APPLIED VEHICLES that come equipped with a factory installed SOS switch, located near the overhead map lamp, also come equipped with a wireless communication device called a Telematics Communication Unit (TCU). With an active NissanConnect® Services subscription, the TCU communicates with the NissanConnect® Services Data Center to provide various security and convenience services. This bulletin contains important service procedures that must be performed properly in order to set-up and maintain the telematics system for the APPLIED VEHICLES. · A table has been provided on the next page that lists the steps required to successfully configure a TCU after it has been replaced. · A CHECK-OFF SHEET has been provided on page 20 to print and check off steps as they are performed. Staple the completed CHECK-OFF SHEET to the repair order.

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 43 model years this bulletin names have filed 3,682 complaints with NHTSA since 2015. 1,025 of them name Electrical System — 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 2018 Nissan Rogue, the 65 owners who gave an odometer reading for Electrical System reported it at a median of 22,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

My 2019 Nissan Maxima (approximately 70,000 miles) displayed a hazard warning indicating a vehicle failure and began stalling without warning. The vehicle was brought to Mossy Nissan on May 28, 2025, where it has remained for over 11 days. The dealership has been unable to identify or repair the root cause of the electrical failure.

The fuel gauge no longer works and the speedometer is inconsistent. The 2021 Murano has a digital spped read out that can be used. The main speedometer can jump around show 45 while running at 73 mph. Or showing 23 when at 33 - so it is clearly a safety issue. This is a low mileage vehicle - with about 18000 miles on it

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 Nissan NTB15-049CC 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 NTB15-049CC 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 NTB15-049CC cover?
The manufacturer filed it against 43 model years: 2022 Nissan Altima, 2021 Nissan Altima, 2020 Nissan Altima, 2019 Nissan Altima, 2018 Nissan Altima, 2020 Nissan Armada and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
