On [XXX], my 2024 Volkswagen Tiguan SEL R-Line AWD (VIN: [XXX] ) was damaged in a deer collision, requiring replacement of the right headlight assembly (P/N 5NL941114D/E, adaptive IQ.Light matrix with turning signal). The part was ordered June 9, 2025, via New Motors VW (Erie, PA) but remains on national backorder with no ETA (dealer confirms not even "top 25" priority). The vehicle has been undrivable and unreleasable from Betts Brothers Collision (Titusville, PA) for 194 days (as of Dec 13, 2025). The shop refuses to release it without the OEM headlight for safety reasonsâoperating with one functional headlight + inoperable turning signal violates FMVSS 108 (S9.1: paired headlamps required for visibility; turning signals per S5.1.1). This creates an unreasonable crash risk (impaired night driving, rural area with no transit). VW Care (Case #[XXX]) refuses ETA, loaner (via Customer Mobility Program), or lease/insurance relief despite $10k+ hardship (6 months payments/insurance + lost use). PA BCP mediation (forwarded Nov 3) and CFPB #[XXX] pendingâno resolution. Similar backorders reported nationwide (e.g., 4-6 month waits on forums/X). VW's systemic parts shortage effectively renders the vehicle a safety defectâdemanding NHTSA investigation for trends/recall/service campaign. No crashes/injuries yet, but prolonged hold endangers if forced release. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
