When slowing down\u2014especially at lower speeds or approaching a stop\u2014the brake pedal briefly loses resistance and the vehicle surges forward as if the brakes let go. I must immediately re\u2011apply hard pedal pressure to avoid rolling into traffic or another vehicle. The vehicle as a result can stop up to six feet past the intended stopping point in some instances. This issue is unpredictable and has occurred multiple times. It creates a serious safety risk.  Toyota performed T\u2011SB\u20110047\u201124 (Brake ECU Reprogramming) on my vehicle, whereafter the brakes seemed to function normally for several months,  but the problem resurfaced and occurred threee time in one week in May of 2026, which prompted me to bring it backk to Toyota for another look.  The dealer has been unable to reproduce the issue and therefore has not repaired it.  The veicle has been returned to me, and continues to have the problem intermittently at a random frequency. Toyota corporate Brand Engagement Center has been notified, and a case was opened (Ref # 260528002416). This case was closed however after telling me that the dealership connot reproduce the problem, therefore they cannot repair it.   This appears to be a brake control defect involving the hybrid brake\u2011by\u2011wire system. Because the failure is intermittent and leaves no diagnostic codes, it is extremely difficult for the dealer to diagnose, but the safety risk is severe. I'd like to advise that I have owned and driven earlier hybrid models (2012-14) that never exhibited this type of brake failure. I'd also like to point out... an internet search of this problem reveals that this problem seems to be prevelant in newer Toyota hybrid models. This was confirmed by the service manager at my local dealership.  I have not been informed of any continuing engineering efforts given the failure of the TSB.","products":[{"type":"Vehicle","productYear":"2021","productMake":"TOYOTA","productModel":"SIENNA HYBRID","manufacturer":"Toyota Motor Corporation"}]}]}
