NHTSA Complaint #11637590 — 2021 HONDA CR-V

Since new, TPMS fails to warn of a low tire unless the car is driven for 5 miles. The TPMS in this car is ABS-based, and each wheel does not have an individual TPMS sensor, rather the wheel speed is what determines if the car has a low tire or not. Brought to Honda several times, could not duplicate, says TPMS performs as it should. Recently had a flat, 3/4 tires were inflated to 37 PSI and the left rear had 4 PSI. Warning light did NOT come on. Drove on low tire for 2.5 miles before noticing I had a flat tire from a nail. AAA came, put the "donut" on the car, and within another 2.5 miles, the TPMS warning light came on, followed by "TPMS System Problem." Not the first time this happened, but I had to buy a new tire because I drove on it flat - which was ~ $267 in Costco for a Michelin Defender 2. Luckily, I did not drive too long of a distance that would've damaged the wheel, but this is problematic especially if you're on the highway. As you can tell, a 4-year-old car with 74K on it, I do a lot of driving. This needs to get rectified.
