NHTSA Campaign 22V034 Confirms Hyundai Windshield Adhesion Flaw; Dealer Fix Set

By mid-February 2022, NHTSA campaign 22V034 was formally on record, capturing the procedural details of Hyundai's windshield recall that had been announced the previous month. For auto glass professionals working alongside or receiving vehicles from Hyundai dealers, understanding the federally documented repair procedure was directly relevant to their work.

The defect involved clear-coat paint applied to windshield bonding surfaces that contained non-conforming flow additives from a third-party supplier. When cured, the paint did not achieve the adhesive grip specified in Hyundai's manufacturing process, raising the theoretical risk of windshield separation in a crash. Hyundai's own testing initially suggested adequate performance, but the supplier's November 2021 self-initiated recall of the paint product changed the risk calculus.

Dealers were instructed to remove affected windshields and reinstall them using the correct materials, specifically ensuring that the bonding surface primer was applied in conformance with Hyundai's standard procedure. No crashes or injuries related to the defect were reported to NHTSA as of the recall filing.

Owner notification letters were set to mail February 25, 2022, directing Santa Fe, Sonata and Elantra owners to schedule dealer appointments. Hyundai's hotline for recall 216 was 855-371-9460. Dealers performing the work were authorized to claim reimbursement through the standard warranty repair process.

The recall procedure essentially described the same primer-and-urethane bonding sequence that trained auto glass technicians perform on every replacement. It reinforced to independent operators that correct surface preparation—not just the quality of the urethane itself—is the variable most likely to determine whether a windshield bond meets the long-term retention forces specified in FMVSS 212.

For shops performing windshield replacements on the affected Santa Fe, Sonata and Elantra models in early 2022—outside the dealer recall process—the February NHTSA filing also served as a reference document. The procedure described in 22V034 confirmed the correct primer and adhesive process, meaning independent shops could verify their own process was meeting the standard that NHTSA and Hyundai had formally documented as the required repair procedure.
