What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 7,280 complaints with NHTSA since 2015. 782 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 2016 Hyundai Tucson, the 100 owners who gave an odometer reading for Electrical System reported it at a median of 60,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.

Common questions
Source: NHTSA, 49 CFR 579.5Is Hyundai TBV 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 TBV 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 Hyundai warranty extension on file lists the ones Hyundai has filed.
Which vehicles does TBV cover?
The manufacturer filed it against 8 model years: 2017 Hyundai Elantra, 2019 Hyundai Santa Fe, 2018 Hyundai Santa Fe, 2017 Hyundai Santa Fe, 2017 Hyundai Sonata, 2016 Hyundai Sonata and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
