Read by machine from the document NHTSA serves (6 pages), read Sep 30, 2026. A part number is shown only where it matches Chevrolet’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 2 model years this bulletin names have filed 262 complaints with NHTSA since 2015. 97 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 2024 Chevrolet Trax, the 15 owners who gave an odometer reading for Electrical System reported it at a median of 16,400 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
The contact owns a 2024 Chevrolet Trax. The contact stated that while the vehicle was parked, the vehicle was remotely started erroneously. The vehicle was taken to the local dealer who determined that the infotainment system had been hacked. The infotainment center software was reloaded but the failure continued to occur.

Vehicle’s digital dash will go completely black, will not respond to touches, radio will intermittently disconnect from Apple CarPlay. Radio replaced, problem persists. Yes the problem has been duplicated on numerous occasions by two separate dealerships and no resolution has been reached.

Unknown. The OEM wipers have a large streak in the main field of vision on the drivers side. They only last a FEW weeks with new OEM parts. I’ve tried getting aftermarket replacement s and they don’t fit properly

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 Chevrolet 23-NA-198 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 23-NA-198 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 23-NA-198 cover?
The manufacturer filed it against 2 model years: 2025 Chevrolet Trax, 2024 Chevrolet Trax. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
