NHTSA Complaint #11705939 — 2019 HONDA ACCORD

I am the original owner of a 2019 Honda Accord Hybrid that I have taken to Envision Honda of Milpitas. I have been consistently maintaining according to Honda’s recommended service schedule. No prior issues were noted. What happened to it is beyond normal wear and tear (failed head gasket). My car only had 78,731 miles on it when incident happened. I did not have any concerns with the vehicle until 11/12/2025 while driving on Freeway. On 11/12/2025, while commuting home from work in the evening on the freeway, all warning lights came on (10/10 lights, including the check engine light). The vehicle could not exceed 50 mph on freeway, and began rumbling. The vehicle had no prior issues. I exited the freeway with hazard lights activated and contacted AAA for assistance. I took my car to Envision Honda of Milpitas the next day (11/13/2025) was informed that the head gasket was blown off. "Cylinder leak down test done and found head gasket is blown on chamber 1 causing the coolant to leak inside the combustion chamber and causes cylinder to misfire. Recommend to perform teardown and inspection, head gasket replacement and re-check." It was dangerous as I was not able to speed more than 50 mph in the freeway while other cars were going fast. I am currently pregnant and was scared.
