NHTSA Complaint #11526017 — 2022 HONDA CIVIC

The TPMS (tire pressure monitoring system) never illuminated to let me know I had a flat tire, and still didn't illuminate even after the entire tread was ripped off the sidewall of the tire. The front left tire was the one that went flat, and had I not been astute to the vehicles behavior, I could have been in a severe accident, as it is a front tire. I noticed the car pulling left a little, but thought it was due to the construction being done to repave the highway. After about 10 minutes of driving, I felt and heard the thumping of a flat tire. I had to drive a few miles to safely exit the highway when I heard the loud bang of the tread separating from the rim and hitting the underside of the car and wheelwell. For the tread to have been completely sheared off, I must have been driving on a flat for a considerable amount of time. The entire time, the TPMS never illuminated to warn of a flat or of low tire pressure. When I got to the dealership, the service writer told me the TPMS doesn't warn of a blowout. I found that to be a strange comment, because I clearly didn't have a blowout. The car was pulling for a little while (over 10 minutes), and then it started the notorious thumping of a flat tire before the tread eventually ripped apart. I couldn't find anywhere in the 2022 Honda Civic Sedan owners manual that states anything to support the service writer. Only that it measures even tire pressure, which it obviously wouldn't have had, so the TPMS should have come on. Even if the TPMS didn't warn prior to a flat, I think it should have illuminated when the tread totally separated from the sidewall of the tire, and it did not. I sat with the car running for at least 20-25 minutes after getting off the highway, and it still never illuminated. From what the Ray Price Honda dealership service writer said, it didn't record any errors either.
