Representative owner complaints: service brakes

67 reports, newest first. Show all

  1. Service brakes, May 31, 2024

    When decelerating from a speed of approximately 25 mph on a downward slope of about 5 degrees, and applying the brakes, a number of things occur: 1) There is a 1-2 second delay in the braking action. 2) When applied the braking action is less than expected for certain brake pedal pressure, which causes the driver to increase the brake pedal pressure 3) When the brake pedal is initially depressed, the speed of the vehicle experiences a slight upward speed bump before the braking action is applied, which is 'light' as described in 2). This behavior is transient. Most of the time, it does not happen. It happens often enough to be of concern.

  2. Service brakes, May 30, 2024

    The vehicle hesitates during right turns, creating a hazardous, potentially dangerous, situation. From research I understand this is a known issue when transitioning between battery and gasoline propulsion. Research indicates this is a known situation, Toyota T-SB-0059-23. However, the TSB expires at the termination of the vehicle 3 years/36 months warranty. As a safety issue, in my opinion this problem should be addressed, regardless of vehicle age or mileage.

  3. Vehicle speed control, Service brakes, Fuel/propulsion system, Jan 30, 2024

    While depressing the brake pedal the vehicle continues to accelerate before finally slowing to a stop. This happens on bumpy road surfaces as well as level road surfaces. There were no warning lights, alarms or messages prior to or during the failure. This issue started around 35,000 mileage and has progressively gotten worse to current day. (Current mileage as of 1/29/2024 is 54,346.) This issue would cause the vehicle to potentially rear end a vehicle you are following or propel the vehicle into an intersection typically controlled by a traffic signal or device. Local dealer has said there is nothing wrong as they could not replicate the issue.

  4. Service brakes, Jan 16, 2024

    I’ve had brakes inspected and was told my brakes look great. However there is major chattering coming off highway to slow on off ramp sometimes they don’t grab as they should and I have to be extra proactive. Sometimes steering back and forth quickly to slow vehicle until the brakes will work properly bringing vehicle to a stop or before a collision could occur

  5. Vehicle speed control, Service brakes, Engine, Jan 4, 2024

    Varias veces mientras conduzco en la ruta la velocidad permitida, el carro frena, pierde potencia el motor, el sistema de aceleración no responde, esas veces me salve de accidentes mortales junto a mi familia, reclame a toyota corporación indicar eso y para ellos no paso nada nunca tomaron en serio, mientras que el carro para reparar eso, paso más de 25 días en las veces que se daño xq prácticamente el carro no es seguro para manejar

  6. Service brakes, Dec 10, 2023

    My 2021 Toyota Highlander Hybrid braking system has, since about 18 months ago, been intermittently failing. When coming to a stop, with my foot on the break, the break releases (or at least feels like it does) before coming to a full stop and then re-engages a moment later once I press harder. Such, gives one a start and is quit disconcerting. There have been times when I was sure the car was going to drift into an intersection. Also I am concerned that such breaking behavior may put pedestrians, cyclists, etc., at risk. I have on two occations reported this to the dealer. They have not been able to reproduce the problem, which is typical of intermittent problems. Tomorrow, December 11, 2023, they are looking at it again. No warning lights or messages have occured. Neither the manufacturer, insurance company, nor the police have inspected the vehicle.

    Electronic parking brake not always disengaging and sending error.

  8. Other or unspecified, Service brakes, Nov 2, 2023

    While slowing and braking to stops (approximately less than 20 mph), the vehicle will lurch/lunge forward. It feels like you took your foot off the brake pedal but you did not. This occurs randomly. It does not happen every time. There are no warning lamps, messages, etc., prior to or during this issue. The vehicle has ~39000 miles. This has been occurring for at least 20000 miles. Risk: If this occurs when close to pedestrians, other vehicles, intersections, etc., it could result in an impact. The dealer could not reproduce but did find online message forums that reported the same issue.

  9. Electrical system, Service brakes, Engine, Oct 16, 2023

    The vehicle has accelerated suddenly when I apply the brakes. It has happened on multiple occasions in different circumstances. I was heading up a hill into a slow stop at a stop sign and once I applied the brakes it suddenly jolted forward for a second until I slammed on the brakes more over riding it. I have had the car for a week and thought it could be just happen stance but it has happened multiple times. The first time there was a car in front of me as I applied the breaks and it is terrifying as I almost crashed into them.

  10. Service brakes, Oct 16, 2023

    My 2021 Toyota highlander hybrid is having seemingly random issues when braking. I notice it most of the time when the vehicle is going downhill. The vehicle will lose braking briefly, and I have to depress the brake harder to slow the vehicle. In that moment when it loses the brake, the vehicle gives the feeling it is lurching forward, which can cause unpredictable stopping distance. It creates a hazard for the driver, the vehicles in front, and the vehicles behind.

  11. Service brakes, Aug 21, 2023

    When slowing down with steady brake pressure, sometimes there is a short pause, 1-2 seconds where it feels like you just lost the brakes. Sometimes this happens when turning and braking too. It isn’t something I can recreate and Toyota opened a case, looked at the car, and said it is normal. Not my 1st hybrid and this is not normal. This has happened many times over the last year and Toyota has looked at the brakes at least 3 or 4 times.

  12. Service brakes, Jun 27, 2023

    ON OCCASSION WHEN ATTEMPTING TO BREAK IN TRAFFIC OR SLOW DOWN AT A YIELD OR STOP SIGN THE BREAKS SEEM TO "FADE". THE CAR DOES NOT STOP UNTIL I PRESS HARDER ON THE BREAKS. I FEEL THAT THE CAR SEEMS TO MOVE FORWARD EVEN THOUGH I HAVE PRESSED ON BRAKE. THE PROBLEM SEEMS TO OCCUR MOST FREQUENTLY DURING STOPING AT THE BOTTOM OF A SLOPE, DURING TURNING OR TRYING TO STOP ON A ROUGH SURFACE. THE VEHICLE HAS BEEN BACK TO THE DEALER ON 2 OCCASSIONS AND HAS APPARENTLY BEEN RECALIBRATED, WITH THE PROBLEM ONLY TO REOCCUR. THE DEALER DOES NOT SEEM TO HAVE A PERMANENT FIX FOR THE PROBLEM. WHERE THIS PROBLEM OCCURS INTERMITENTLY THE DEALER HAS NOT BEEN ABLE TO REPLICATE THE ISSUE. TOYOTA HAS ISSUED A TSB0017-21 TO RECALIBRATE. ON OCCASSION I FELT I WAS GOING TO REAR END THE VEHICLE IN FRONT OF ME OR DRIFT INTO THE INTERSECTION WITH ONCOMING TRAFFIC. BREAKING HARD TO REMEDY THE PROBLEM COULD CAUSE MY VEHICLE TO BE REAR ENDED. TO MY KNOWLEDGE, THERE WERE NO WARNING LAMPS, MESSAGES OR OTHER SYMPTOMS OF THE PROBLEM PRIOR TO THE "FAILURE"

  13. Service brakes, Jun 22, 2023

    While braking at random times, at any speed, the vehicle surges forward. This makes you have to break harder to get the vehicle to stop. It seems as if the breaks do not work at all for a brief period. I have brought it into the dealer, my car is no longer under warranty, they found nothing wrong.

  14. Service brakes, Jun 16, 2023

    With increasing frequency, we have noticed what feels like the brakes releasing after being applied. This has happened at low speeds 5-10mph and mid speeds of 20-30's mph. It seems to happen more often when cornering or coming to full stop at low speeds. When the brakes let up it seems almost to accelerate the vehicle. So far we have been able to avoid a collision, but we are fearful that we may hit and injure someone as a pedestrian or in another vehicle. We have complained to Toyota twice now and had the car looked at. They can't find anything wrong and tell us it is normal for hybrid cars?

  15. Service brakes, Jun 11, 2023

    When braking, often it feels like the brakes are not engaged, not right away, but during the braking process. This causes the vehicle to surge forward like there are no brakes. Immediately you feel like the brakes failed, then you push them again, they work. It is very random with no reference to different speeds, inclines, never know when it may happen. It has caused many near misses for our family whenever this happens.

  17. Service brakes, Jun 7, 2023

    While in the process of slowing down, especially through roundabouts, the car braking systems seem to fail for a few seconds and actually surge/accelerate forward. It is sporadic but has happened to me more than 10 times in the last 6 month but I worry that it will jet forward into another car. I have notified my Dealer Ed Martin of Noblesville and they have stated this is the hybrid braking system (part of how it works). I understand this system but it should fail while braking. I was dismissed and wanted to report it as I did see on-line of other complaints.

    I came to a stop sign in my neighborhood on Windy Drive and I heard what sounded like a gunshot. I immediately put my vehicle into park and got out and noticed that the sunroof glass was shattered. The best description I can give is the glass looked like a volcano where the broken pieces were facing upward. I then proceeded to my local Toyota dealership located in Alexandria, Louisiana. They told me my car was out of warranty and provided me with a quote of $1,450.00. I believe that this occurred due to a defect from the manufacturing process and I don't think the consumer should be responsible for the cost to fix the sunroof. After researching on the internet, I see several complaints from other Toyota owners that have experienced the same incident and I feel this should be a recall on Toyota's part. I am frustrated that I have to pay $1,450.00 for damage that I know was a manufacturing defect after I researched and found hundreds of other consumers with the same experience.

  19. Service brakes, May 19, 2023

    When coming to a stop, when I apply the brakes, they stop working and I have to press harder on the petal to stop the car. It feels like the brakes "let go" , it is scary since the brakes stop working. I have searched the web and found the Manufacturer has been sited with an issue on another model. Toyota Camry- NHTSA 21V890 - bad vacuum pumps- "van cap" - many break causes the break to lose brake assist . I am planned to see my dealer for its 35000 mile checkup and plan to report to the dealer this issue- 5/19/2023

  20. Service brakes, May 17, 2023

    This occurs occasionally when I brake. I have my foot softly on the brake and the brakes cut out. The car feels like it accelerates/surges forward rather than slowing down. I need to apply the brakes hard to then stop the vehicle. I never know when it will happen. When it occurs and a car is in front of me, I have had near miss accidents. The issue seems to be worse on bumpy roads or downhill road when I tried to hit break to slow down or stop the car. I brought the car into dealer on 5/17 which they connected with diagnostic tool. However it showed everything is normal. The service agent told me there is one case just reported few days ago with same issue. Toyota sent expert to dealer to investigate the issue so I need to come back on same day for further investigation.

  21. Power train, Service brakes, May 11, 2023

    While parking, the shifter was inadvertently left in reverse. The engine was turned off while foot was still on the brake. After preparing to exit the car and removing my foot from the brake, the car began rolling forward until I noticed and slammed on the foot brake. We are used to the vehicle parking brake engaging automatically as there is no way to do so manually, that we know of. There was no warning that the shifter was not in park and no audible or noticeable visual notification that the vehicle was not in park. In some cases, on a flat surface when the vehicle wasn't in park, it didn't allow me to shut off or arm the security system. In this case, I was able to stop the vehicle and fortunately there was nothing in front of the vehicle. Since the vehicle was powered off, anti-collision likely would not have stopped a collision.

    What component or system failed or malfunctioned, and is it available for inspection upon request? Braking system How was your safety or the safety of others put at risk? Vehicle braking is unpredictable. Has the problem been reproduced or confirmed by a dealer or independent service center? We can not get the issue to be reproduced, braking variables seem random Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Inspected by Toyota Dealership Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warning lights or computer codes go off Assessment of the incident: When applying the brakes to stop or slow, the brakes will slip for a second then re-engage. This can happen when coming to a slow stop or an abrupt stop. The exact parameters to cause this issue are unknown at this time and is unpredictable. My dealership is aware and has documented the issue but has been unable to reproduce the issue. Never experienced this before with other Toyota hybrids I have owned.

  23. Other or unspecified, Service brakes, Forward collision avoidance, Feb 22, 2023

    my car experiences intermittent acceleration when applying the breaks. It lunges forward for some reason. It has also not stopped when hitting the breaks hard but lunges as well. I am using the last date that this happened.
