For the last 14 years, a check engine light has been coming on telling me that I have a fuel canister emissions leak because the canister is cracked. In 2016 2.87 million Toyota Priuses were recalled with the fuel canister crack issue. For unknown reasons Toyota has refused to fix this dangerous issue and has told me that my car was NOT included in the recall. I do not believe Toyota is being honest in their continued denial of this dangerous issue and excluding my 2010 Toyota Prius. This issue has been ongoing since the car was new.

Subject: Vehicle Safety Defect Complaint / Request for Investigation Review Vehicle: 2010 Toyota Prius VIN: [XXX] Component: Electronic Brake Booster / Pressure Accumulator Assembly Dear Administrator, I am writing to formally report a critical safety defect in my 2010 Toyota Prius regarding the electronic brake booster and accumulator pump assembly. This component exhibits classic failure symptoms—specifically a distinct puffing, ticking, and pressure-loss noise directly from the brake pedal mechanism—which points to internal nitrogen or hydraulic pressure leakage. This component was previously the subject of Toyota’s Customer Support Program / Safety Recall (Campaign ZJB / D0H) due to fatigue cracking in the internal accumulator bladder. However, Toyota's arbitrary cutoff timelines have left me completely unprotected, even though the underlying engineering defect remains identical and poses an active, catastrophic threat to public safety. The real-world implications of this failure are severe: •Daily Risk to Life: I am a self-employed small-business owner who relies on this vehicle daily to travel between clients across the greater [XXX] area. Because of this failing component, I experience profound fear every single time I drive that I will completely lose my brakes in heavy traffic. •Financial Barrier to Remedy: Authorized Toyota dealerships have quoted me several thousand dollars for the repair. Due to a 40% drop in my business income amid the soaring cost of living in [XXX], I cannot afford this repair, nor can I afford a rental car or alternative transportation. My car is my literal lifeline, forcing me to drive a vehicle with a compromised, safety-critical braking system. •Unfair Expiration of Safety Remedies: My vehicle was serviced by authorized Toyota dealerships twice during the active primary campaign window (on XXX at 36,675 miles, on 08/30/2019 at 41,238 miles), where recall status checks were routinely requested INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I had begun to notice a slight shimmy at highway speed for a few days, but it wasn't pronounced enough to cause concern, especially since the weather was very windy and already subjecting the car to heavy crosswinds. On Monday, [XXX], the shimmy became suddenly more pronounced, so I pulled off the highway ([XXX]) and parallel-parked on street in Cambridge, MA. While parking, I heard a loud creaking and grinding sound, and the car no longer responded to steering inputs. I exited the car and noticed the rear driver's side wheel protruding at a strange angle from the wheel well. I called AAA and the tow truck driver discovered that, behind the wheel, where the wheel meets the rear axle, the arm had rusted clean through. In other words, the wheel had completely fallen off, and was being held to the car only by the brake line. I was towed to a mechanic in Salem, MA. Both the Salem mechanic and the AAA tow truck driver said that they had never seen anything like this in all the years they'd been servicing cars. I told them that the car had never been in a flood or otherwise involved in the kind of extraordinary event that would cause more than typical rust exposure. Had the wheel come off at highway speed, I could have been seriously injured or killed. The issue did not seem to have been caused by driver/owner oversight or normal wear and tear. It seems highly unusual and potentially indicative of a defect or manufacturing error. I hope other 2010 Prius owners are aware of the vehicle's susceptibility to this issue. And I would like Toyota to take some responsibility for the high cost of repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The color of my Prius 2010 starts with 070, blizzard white pearl. The body started peeling. I have visited Toyota dealer on 12/29/25 with this issue and got to know that this issue is well known but the service campaign was finished around June, 2025. I own this car from 2023, October and visiting Toyota dealers for services regularly, but never thought that this issue was a common issue by Toyota. Also, I have not heard anything from dealer. It is also true that the issue was not severe and even if it was, I was not attentive to that, apologize for my ignorance. However, it seems the issue is getting worse day by day. I did not receive any notice from Toyota about any campaign about this issue. My Toyota dealer recommended me to reach out to Toyota if any courtesy repair can be done on my vehicle. I reached out to Toyota, but seems to me they cannot do much. Can I get any help in this regards?
