NHTSA Complaint #11668776 — 2019 TOYOTA TACOMA

I’m filing this complaint regarding a known issue with the A/C evaporator core on my Toyota Tacoma (3rd generation). The evaporator core has prematurely failed, leading to a complete loss of air conditioning and, more importantly, reduced defrosting and defogging capabilities that directly affect visibility and driver safety. This issue is widespread and well-documented among Tacoma owners, and Toyota has issued TSB T-SB-0145-20, acknowledging that corrosion in the evaporator core leads to refrigerant leakage. Despite the known defect, Toyota has not issued a recall and is charging owners thousands of dollars to repair a part that is failing far earlier than expected. In my case, the system began blowing only warm air, and the defroster can no longer clear moisture from the windshield, which is a serious safety issue in humid or cold conditions. This should be treated as a systemic defect, not regular wear and tear. Toyota needs to be held accountable for this manufacturing flaw, which affects safety-critical components like the defroster and visibility systems.
