BYD said a supplier coding error caused a front-to-rear rim mix-up on some Tang SUVs and that it will offer affected owners free adjustments and restart their whole-vehicle warranties from Nov. 11.
BYD attributed the assembly mistake to a coding-entry error at wheel-rim subassembly supplier 湖北铂遇实业有限公司. The company said it corrected the coding, after which the supplier installed visual checks on its production line to help prevent a repeat.
BYD said its tests indicated the mix-up had not changed handling or created a driving-safety risk. It plans to invite affected owners to service centers for free inspections and professional rim adjustments, and offer either a loaner vehicle or compensation for transportation costs.
BYD did not disclose how many vehicles were affected or identify the production batches. Shanghai Securities News reported that consumer complaint platforms had logged more than 100 entries by Nov. 11, with complaints appearing from Nov. 5. CarNewsChina reported Nov. 8 that owners of the 950-kilometer rear-wheel-drive version had raised handling concerns.
