NHTSA Complaint #11687537 — 2023 TESLA MODEL Y

Summary of Complaint: My 2023 Tesla Model Y has had two roof glass failures in three months (two glass roof replacements). Both times, the glass cracked from small road debris while driving under normal city conditions. Safety Concern The roof glass appears unusually fragile and prone to cracking, raising concerns about whether it meets industry standards for impact resistance and occupant safety. The rapid failure rate (two roof glass panels in three months) suggests a potential design or materials defect rather than isolated incidents of road damage. If roof glass panels cannot withstand normal road debris, this presents a safety risk for drivers and passengers, as well as for other motorists if large shards detach while driving. The roof glass seems unusually fragile. Two failures in such a short time suggest a design or material defect. If the glass cannot withstand normal road debris, it may not meet durability or safety standards. There is also risk to occupants and other drivers if roof glass fails while in motion. Request: Please investigate whether the 2023 Tesla Model Y roof glass meets required safety standards, and whether this issue is affecting other owners.
