In owners' own words
Brake System Warning light ABS warning light Slip indicator light 6/3/2022, while driving on the highway the above warning lights illuminated. I depressed the brakes but failed to engage. I was able to slow down by shifting the gear into âBâ. Eventually the brakes engaged and I brought the car to a stop. Toyota created customer support program ZJB but the warranty covered a period until August 2021. Service brakes
The brakes total disengage when applied on bumpy roads then work again after getting to a smooth surface. I reported this to the service manager at the new car owner meeting at Toyota and was told that I just have to get use to antilock brakes. I haven't gotten into an accident yet but I had several close calls almost hitting cars in front of me on bumpy roads. Has there been a recall for this problem? Service brakes · reported at 300 miles
When I am coming to stop at an intersection on a bumpy or uneven or snow covered road and apply the brakes the car lurches forward instead of stopping. I am lucky I haven't hit a car in front of me or a person crossing at the intersection. I have been reading the other complaints and they describe exactly what is happening with my car. I haven't yet tried to get this fixed, but I am starting today. Service brakes · reported at 60,000 miles
