Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
DL: On December 20, 2022, a settlement of claims for certain low pressure fuel pumps was approved by the federal court. The settlement includes Toyota?s agreement to provide a Customer Support Program for certain 2015-2020 model year (MY) vehicles that were not previously involved in a Safety Recall or Special Service Campaign related to the low pressure fuel pump. The purpose of this Customer Support Program letter is to help clarify how to administer this coverage in accordance with the settlement.

I pulled up to a stop light and applied the brakes. I stopped but while I was sitting with the brakes applied, my 4runner started rolling forward. I had to push the brake peddle to the floor to a point I could barely reach to get it to stop again. I took it to the dealership and they agreed the brakes were not acting right. They could see on the computer that something was wrong as well. They…
Re: complaint 11043597. Experienced complete loss of brakes. No warning light. Brakes were reset? After vehicle arrived at dealer. ECU did not download any warning codes. Based on this, Toyota will not repair/replace corresponding brake components and want me to drive the car. This was a complete brake loss with pedal to the floor and no brakes. Used parking brake and transmission to…
Brake failure. Approaching 4 way stop. Went to apply brakes, heard-felt a pop and pedal went to floor and lost all braking power. This is a new vehicle. Had to use parking brake and transmission to slow to stop. Fortunately only going 30mph........still rolled into center of 4 way intersection. Thank god no cars in front of me or there would have been an accident.
While driving at full speed on the freeway, another vehicle stopped suddenly in front of me. My brake pedal was soft and went down almost to the floor. Rapid pulsing of brakes, as would be expected with the ABS (antilock brake system), did not occur. I pulled around to the shoulder and barely managed to stop in time to avoid a collision, which was quite a frightening experience. I have had a few…
In motion, from street turning into store parking lot, brakes faded completely to the floor. Lifted off and applied pedal to stop. No leaks, plenty of fluid. I will check with another dealer. There are quite a few cases of this on the t4r forums. Dealers can not duplicate. This is very dangerous to not have an answer for. Opinions are electrical antilock issues.? (there is no air in lines, no…
When you apply the brakes with full force while driving; the brakes lock up for a short period of time on one side of the vehicle, causing the vehicle to swerve uncontrollably. This is extremely dangerous vehicle when the brakes are applied with hard force at speeds at around 35 MPH or higher. Luckily I am a very experienced driver and car handler and was able to react quick enough to control the…

A quarter of owners report trouble before 7,600; a quarter make it past 15,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.

Independent shops typically charge around $450 for brakes repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
