2008 Toyota Prius

2008 Toyota Prius gen2 with 139k miles. ABS, Brake, parking brake, and Traction Control lights all illuminated while driving the other day. Potential is losing all electronically assisted braking function in the car. Problem has been confirmed by local independent service center. Independent service center pulled codes: C1256 Accumulator low pressure C1378 Capacitor Communication Malfunction C1391 Abnormal leak of ACC pressure all consistent with ABS accumulator failure. Recommending ABS modulator assembly replacement at $2742.66 Toyota had a warranty enhancement program that covered this component: Warranty Enhancement Program – ZG1 2006-2007 Model Year Highlander Hybrid & 2004-2009 Model Year Prius Vehicles Extension of Warranty Coverage for Brake Actuator Assembly This Warranty Enhancement Program provides enhanced coverage to the vehicle’s “New Vehicle Limited Warranty” as it applies to the Brake Actuator Assembly. The specific condition covered by this program are repairs related to an internal malfunction of the Brake Actuator Assembly. If the condition is verified, the vehicle will be repaired with a new Brake Actuator Assembly at no charge under the terms of this Warranty Enhancement Program. • The Primary Coverage offers warranty enhancement until December 31, 2017, regardless of mileage. • After the Primary Coverage end, the Secondary Coverage is applicable for 10 years from the date of first use, or 150,000 miles, whichever occurs first

Brake pedal became hard and vehicle was difficult to stop. ABS warning light appeared on dashboard. This is a problem that Toyota has addressed previously by extending the warranty period to 10 Years/150,000 miles. My vehicle has 122,000 miles on it but the 10 year extended warranty has expired. I took the vehicle to a local repair shop and they confirmed that there was a problem with the brake actuator assembly. Now, Toyota says it would cost over $3000 to remove and replace their already defective part.

ABS failed and mechanic tells me my actuator needs replacement which is a known issue with my generation of Prius.

Odometer Fraud. The contact purchased a 2008 Toyota Prius. The contact discovered that there was a mileage discrepancy. The vehicle was a direct purchase from the previous owner on August 3, 2025. The contact made other reports with a personal lawyer, the State Attorney General's Office, and AZ.FraudReport Agency. The contact had not heard back from the other contact regarding the other reports made. At the time of purchase, the vehicle mileage was 50,000 miles, and at the time of registration, it was discovered that the mileage was over 200,000.

The ABS brake booster/accumulator is going out and this has been a known issue with Toyota for years. Mine was purchased used a few years ago and had no issues until recently, as the pump is running more frequently.

My name is [XXX] ,i am filing this report on behalf of My daughter [XXX] the driver of the vehicle that involved with the unintended acceleration on the 2009 Toyota Prius .On a good clear morning on [XXX] . My daughter drove the 2009 Toyota Prius to work- when she enter to the parking lot at the speed round 5 mile/hour . Just when she was making a left turn on to the entrance gate with her left foot on the brake pedal . On a sudden the vehicle RPM unintended rev up too high and the vehicle had an unintended accelerating to move forward aggressively causing lose control of the steering . Also she could not brake even though her left foot was on the brake pedal and pressing hard to try to stop the vehicle . . This dangerous incident causing her Prius to bumped into the electrical gate panel control box . The accident caused some damages to her Prius and to the entrance gate control box though no body was hurt . But it got us through the terrible experience because it could kill some one for sure . My daughter been driving this commute car daily in the past 5 years and she has the skill of 20 year driving with good record . This Prius of her still have all OEM equipments with no add- on parts-,no modifying part on any systems what so ever- and NO extra floor mat cause we been warned before about the possible of unintended acceleration causing by aftermarket floor mat to any vehicles. . We feel unsafe after the mystery accelerating problem on Toyota Vehicle that could take people lives . So the mystery unintended accelerating on car is REAL . I am currently checked and find out her Prius has 2 incomplete recalls (un-notice to us ) but none of them related to the unintended acceleration problem . We would like the NHTSA to take this problem seriously to save people life . I will included photos of this incidents and willing to provide all information if needed to address this problem, again to save lives .

I recently took my vehicle to the dealership because all the hazard lights on the dash came on. They diagnosed it as an issue with the inverter water pump and suggested that the engine was overheating, which was causing the hazard light to appear on the dashboard. So I had them replace that part and everything was fine. A week later, I went to drive to work and my entire dashboard was out. My radio, clock, blinkers, and brakes worked, but I could not see the speedometer, gas gauge, odometer or any other dashboard features. When I tried to restart the car, it wouldn't turn off. I tried several times and even got my husband to try. When we couldn't turn it off, I drove blindly straight to the dealership. They diagnosed the issue as being a problem with the combination meter. Recently, I found out that there was a Customer Support Program through Toyota that replaced the combination meter in my same car model. This service expired in 2017. I got the car in 2020-21. Thankfully I was home, and was able to follow my husband to the dealership. I'm not sure what I would've done if this happened while I was out. I am also have traction issues with the brakes. When I try to brake on a slope or incline, the glide hazard lights come on. It's happened several times when it's raining, but it's been happening more when it's not. I typically give enough space between myself and the car in front of me, but it's concerning that the brakes lock up when I'm on any type of sloped surface.

Brake actuator fails. Subject to prior recalls, but they're continuing to be an issue. This vehicle, and thousands of others like it, the electric brake actuator/pump starts running constantly then fails entirely. When that happens, as has to mine, the vehicle has NO power brakes, which can and does cause the vehicle to crash. The replacement part is over a thousand dollars. Toyota has engineered a failure mode that creates massive continuing profits.

Incident Summary: While relocating from northern to southern Alabama, I experienced a sudden and concerning failure in the vehicle’s braking system. While driving, multiple dashboard warning indicators were triggered simultaneously, including: •Brake warning light •ABS light •VSC (Vehicle Stability Control) light •Additional system fault alerts This happened unexpectedly and severely impacted my ability to drive the vehicle safely. Given the nature of these warnings and the critical systems they pertain to, I immediately took the vehicle to a certified Toyota dealership for diagnostics and repair. Following inspection, I was informed that the ABS actuator and related components had failed and would require replacement at an estimated cost of nearly $3,000. I was further advised that while this issue had been part of a previous recall or customer support program, that program is no longer active. Rationale for Cost Coverage Request: 1) Known Safety Issue: This ABS/VSC failure aligns with prior technical service bulletins and recall actions issued by Toyota for Prius models of this era. The abrupt system failure while driving raises significant safety concerns. 2) Purchased from Certified Dealership: The vehicle was purchased from an authorized Toyota dealership. I trusted that all known recall issues would have been properly addressed prior to sale. 3) Recall Program Timing & Fairness: The original recall or warranty enhancement was tied to a timeframe or mileage limit, but given that this issue has not been resolved and is now manifesting as a serious failure, I believe an exception should be made—especially since it was known to affect vehicles like mine. 4) Customer Loyalty and Safety Assurance: I have maintained this vehicle responsibly and expect Toyota, as a brand committed to quality and safety, to assist with this issue in good faith. Request: I respectfully request that Toyota cover the full cost of diagnosing and repairing the ABS system issue.

The error lights related to the ABS, VSC braking system can suddenly come on, the antilock brakes stop working, and breaking power is greatly diminished. This occurs without warning and when it does, the brakes do not work safely and it is more difficult to bring the car to a stop. I have taken the car in to repair shops who have confirmed the issue. This malfunction produces error code C1256 and multiple mechanics have confirmed it is related to a faulty ABS Actuator Assembly and recommend immediate replacement of the unit. This is a common and known issue with these cars. I have been quoted a range of $2,100+tax to $2950+tax to perform the repair using a brand new part from Toyota.

The contact owns a 2008 Toyota Prius. The contact stated that while driving at various speeds, the instrument panel failed to function as intended. The contact stated that the instrument panel went blank. The contact stated that the failure was intermittent at first but had become a permanent failure. In addition, the front headlights and rear taillights failed to function as intended. The vehicle was taken to the dealer; however, no cause for the failure was found. The vehicle was not repaired due to the cost. The contact stated that on a separate occasion, while driving at various speeds, the front headlights failed to work as intended. Upon inspection, the contact noticed that the bulbs had melted into the wiring harness. The contact stopped driving the vehicle at night. The manufacturer was not notified of the failure. The failure mileage was approximately 90,000.

brake actuator assembly failed

The dashboard of the car fades in and out randomly. Sometimes the dashboard doesn't come on at all. And when it does come on, it appears the mileage may have not increased even though the vehicle has been in use. This means that when the dashboard is off the driver is guessing at speed of the vehicle and at the fuel.

Brake actuator failing just like everybody else

Loud grinding noise coming from engine compartment accompanied by a loud shrill alert. When attempting to pull over to a safe place, I put my foot on the brake pedal, but immediately became distressed because it felt like I had no brakes at all. After applying extreme pressure to the brake pedal, the car did begin to slow down, albeit very slowly. I had 2 passengers in the car (ages [XXX] and [XXX] ) and I felt their lives were in jeopardy. Upon researching, I found that Toyota has known about this ABS problem for quite awhile (at one point, they even extended the warranty on the faulty parts). With the gravity of losing the ability to brake while driving, reasonable people would conclude that a recall is in order. It does not matter if it is voluntary by Toyota or mandatory by the appropriate government entities. I, literally, feared for my life and the lives of my passengers. I am grateful it didn't happen while traveling at highway speeds because the outcome could have been much much worse. I sincerely hope that my government who is in charge of protecting it's citizens against known automobile dangers, will take the necessary steps to initiate a recall for all Toyota vehicles that have this serious ABS problem. My fear is that those decisions are made by algorithms and actuarial data rather than by reasonable common sense. I certainly hope there isn't an arbitrary number of deaths before a recall is made. What if one of your family died as a result of purposeful inaction. The diagnostic codes for my Toyota are C1256 and C1391. These both point to serious problems with the ABS system ( actuator, accumulater etc.). Please consider investigating this common and life threatening problem.

I have a 2008 Toyota Prius (172k miles). From the sounds coming from the ABS Brake actuator and soft breaks, it is clear from my research online that I will soon have a failing ABS brake actuator. I have the code C1256 thrown which is ABS "Accumulator Low Pressure" Read more: [XXX] I do not feel safe driving it as it is clear one day the brakes will suddenly go out on it. This needs repaired.

About 3 years ago we started getting the red triangle of death with 2 amber lights on display the vsc and the round circle with the exclamation point in the center. This could happen in 500 miles or it could happen tomorrow. When this happens I loose all exceleration and air conditioning and a orange car emblem with an exclamation point in it on the display screen. Once safely off road press power button off and back on and everything is back to normal except red triangle and car on display screen car is then drivable again. Using a code reader to check codes no codes appear but still have red triangle. Leaving car set for a period of time and restarting car and red triangle is extinguished. Have to drive in right lane on freeway in case it wants to quit. The most recent time was last week had driven it about 80 miles with a stop about halfway for 1 hour and stopped for a movie came back got in car started it and within 1000 feet got the red triangle, was in left turning lane with red light, shut off and restarted and was able to drive again as in all other times, took it to a neighbor who had a code reader(about 9PM) and no codes found, he reset it and red triangle extinguished. This type of happening is very unnerving to say the least, dont know when or where it will lay down with us. Don't know if anyone else has had similar issues with their Prius ours has 213,000+ miles on it. Original hybrid battery it was checked in 2015 and some cells replaced by a shop certified to replace cells in this battery. Thank you.

Brake ABS and front brakes have completely failed because a software error where the and cannot be calibrated and terminates during calibration. The car only has rear brakes which frequently lock of and cause a safety issue. Front brakes completely disabled due to a software calibration issue

In temperatures above 95 degrees the vehicle shifts into neutral while driving, and you need to physically hold the shift lever in Drive or Reverse to keep it out of neutral. It won't go into park at all unless you restart. This could cause a fatal accident while driving, particularly on the freeway. It has not yet been confirmed since it only happens at very high temperatures, which is rare where I live (Seattle). There has been quite a lot of discussion on Reddit and other internet sites about this problem with Priuses, particularly the 2008 model. I have an appointment with my mechanic to replace the shift lever assembly, which appears to be the most commonly referenced fix. There are no warning lights, other messages, or symptoms before or while this is happening. The problem resolves when the air temperature goes back down.
