NHTSA complaint #11698448

Owner complaint summary

I believe the break booster on my 2019 Toyota Corolla is defective. This caused my stopping distance to increase significantly, making it difficult to control my vehicle and putting myself and other drivers at risk. There were no warning lamps or messages or other symptoms prior to the start of the issue on October 10, 2025. I quickly took my car to a local mechanic the next day who said I had an issue with my brake booster. To make sure this was the issue I followed up and went to a Toyota dealership for a diagnostic. They initially told me that "all brake systems components were functioning normally at this time" and that all I need to do was to change the break fluid. I did this, but the problem persisted. I then returned to the Toyota dealership for a second diagnostic. This time they noted that the brake master cylinder and brake booster are loosing pressure internally and need to be replaced. When I googled this I saw that some 2019 Corolla (and other hybrid) vehicles were included in a 2019 recall for a brake booster pump that could fail, leading to a loss of braking assist, similar to what I was experiencing. I brought this up with the Toyota brand engagement center. They said there was no recall at this time on file, but that they would put me in touch with a representative who would manage my case (case # 251015000598). The representative would not pick up my phone calls. I was not able to speak with him. After many calls, a different representative spoke with me and told me that the case was already closed and that the assigned representative said he had explained to me why. This is not true as I had not had the chance to speak with him. I am concerned that Toyota has not given my break booster pump due diligence and is dismissing my legitimate safety concern and I would like to report this safety problem to the NHTSA.
