NHTSA Complaint #11685840 — 2021 TOYOTA RAV4 PRIME

The car has a grinding sound and a brake slipping feeling that occurs while traveling and braking over rough pavement. It does not happen consistently, but it does happen fairly regularly (every 2-4 weeks). Note, the grinding sound can range from subtle to quite loud, depending on bump/timing of braking. This has been happening since I purchased the car and continues to happen, which is why I put today's date as the incident date, and I have been bringing it up with the Toyota maintenance department at most maintenance appointments. Their shop manager has driven it and thought I was mistaking it for the ABS activating. I have driven it with him, ABS has activated, and when he pointed it out to me, I have let him know that what is happening is definitely something different than the ABS activating. I have tried to find a location to show them to replicate it with the service center, but it happens randomly on rough patches. For example, it happened on a spot near the dealership that I thought I could use to show them, but when I drove over the same area again and braked, nothing happened. So, I have not been able to replicate this with the service center, but it is most certainly happening. I have notified Toyota through their consumer contact system that this issue is going on and they said Toyota tracks issues like this. However, no resolution has been offered. Other Toyota Rav4 Prime owners of the same year have experienced this (see [XXX] and [XXX] ). Although the maintenance manager was stumped, he said at a recent visit that another Prime owner voiced the same type of thing happening. Toyota needs to investigate to determine what the issue is and remedy the issue. I am concerned this could lead to a larger issue and is a safety recall issue that warrants immediate attention. It does not seem that Toyota is taking this seriously. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
