2008 Toyota Prius

Water pump failed after replacement in 2013 with 30k miles, car had only 93k miles when failed again in 2016. The potentiometer part failed, there is corrosion in the part. Was in freeway when it failed. I have reported this to different representatives. I was charged more 1.5k for a replacement of a faulty part that should last more than 50k miles.

the cruise control was inop, technician said it was a clockspring failure, replaced the clockspring with a new part from walmart, then at times, the airbag failure light would come on, paid a technician to replace the replacement clockspring with an new one and the failure stopped, walmart is selling a part that could result in death

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.

In 2025 I decided to clean the hybrid battery fan. I removed the side panels and found that the fan to battery duct had never been installed. I am the original owner and no one had ever removed the inside panels or had reason to remove the duct. This has likely resulted in the overheated battery which now needs replacing even though I have only 161,000 miles on this car which I have always maintained without fail regarding oil changes and other maintenance tasks.

In the cars digital instrument cluster have problem on the same model many of cars because I know many of friends that have same model car and I get problem so I go to the mechanic and the mechanic says it is a manufacturing problem on that same model have same problem I repair it twice and now it again appears it's also a safety concern because the problem is the light is completely go out completely blank so we are not able to see the vehicle speed vehicles fuel gas and vehicles other information that shows on digital cluster so if we drive in this condition we don't know how much speed is on my car right now

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.

Randomly my instrument panel goes blank while in motion and can only be retrieved by hard turning the car off when stopped, you loose your speedometer, lights, and all until reset. Other issue with speedometer readings that are consistently off between 5-15mph with no fix, resolutions or repairs.

Trunk lock will not unlock or allow opening, back latch malfunctions, when car battery dies or car looses power《• you cannot open the trunk and access emergency tools/equipment and battery to jump car. •》You have to access by climbing through the front of the car if you are able-bodied too. There is no opening handle from the inside of the trunk to be let out, scariest and one of the most important major safety concerns, theres no emergency exit from inside vehicle. Water/snow/ice also falls down into the vehicle when opening hatchback, it slides inward from hood of car or slides back from rear windshield and door, causes water to be pooled up in my battery compartment.

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

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.

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.

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.

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.

The contact owns a 2008 Toyota Prius. The contact stated while driving at various speeds, the instrument panel went blank. The contact stated that the failure was intermittent at first but had become a permanent failure. The vehicle was taken to the dealer and the contact was referred to the manufacturer for assistance. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and informed the contact that there were no recalls no warranty coverage on the vehicle. The failure mileage was approximately 72,000.
