2013 Toyota Prius

I pushed on the gas, the car started mildly shaking under the hood( the engine) then I released my foot off the gas and the shaking ceased. I the. Attempted to accelerate again and the car started violently shaking so I released my foot from the accelerator and turned the car while coasting onto a side road where I traveled back home. Had the car towed to mechanic. He said the engine needs to be replaced as the pistons are damaged. My car has 196,000. I will have the engine replaced as my other 2012 engine just did the same similar thing and I am out two Priuses with blown engines. There were no warning lights and no previous issues or signs prior to the catastrophic events.

ABS Brake Warning Light On-stays on-this just happened within last 2 weeks. Not sure on safety measures but unsure if I keep driving it the brakes will just give out. The problem has been confirmed and seen by Tire Max but no diagnostic tests were ran. The just saw the light was on. No one has inspected the vehicle component by the manufacturer, police, or insurance company. No warning lamps prior to the problem but the ABC Warning light stays on while cranked and it first appeared about 2 weeks ago. I do want to add that a similiar recall or warranty had been put out by Toyota on Sept 4th 2020-(T-SB-0089-20) for 2012-2014 Prius V & C stating: "Some 2012-2014 model year Prius V hybrid vehicles may exhibit a condition where the brake, ABS, and/or TRAC warning lights are on and/or a Check VSC message displays. Diagnostic Trouble Codes (DTCS) C1391, C1252, C1256, C1253 may be stored. This condition may be caused by a small internal brake fluid leak inside the brake booster assembly with master cylinder. The warranty was for Prius V or C but my Prius(no V or C) has been affected with the same issue but Toyota will not honor this warranty or recall due to the problem not showing as specific to my vin#. So I am reporting this problem so it can be submitted that there is a similar problem with my Prius as well as the Prius V or C so others could submit their problem as well. I cannot afford to fix this myself. I need Toyota to back up their cars.

I was driving home on a busy street in Houston, TX on a clear day. I tried to slow down due to traffic & the following warning lights appeared on the dash: red brake system warning and yellow brake light, ABS, brake system warning light & the slip indicator light. Right after, I came to a red light & started to brake, the car felt like it was on ice and couldn't stop properly. Fortunately I didn't have to come to a complete stop because there were many cars in front of me and the light turned green. when I stopped applying pressure to the brakes the car sort of shook side to side. Each time I had to brake, the car felt like it was on ice, I had to put the hazards on & give myself a very large amount of room to stop the car. While at a red light I turned the car off/on; no change in the dashboard lights. I turned onto a street w/ less traffic; pulled over, turned the car on/off again and no change. I was less than a mile from home so I drove the rest of the way w/ my hazards on & never went faster than about 15 mph; even at that speed the car took too long to come to a complete stop, it felt like I almost had no brakes at all. Thank God I wasn't on the highway w/ no brakes!! This is a HUGE safety issue, someone could die or be seriously injured. Had the car towed to a Toyota dealership on Mon 1/15/24; they said there was a brake fluid leak in the master cylinder & malfunction of brake booster pumps, the code was C1391; both parts needed to be replaced. Total cost for repairs $3800. Had the car towed to a mechanic, paid $2600 for the same service. Per my research this is a known problem with this generation of Prius', Toyota offered an "enhanced warranty" to replace the parts if they were broken, but the dealer said my warranty expired in 2022. Why weren't owners made aware of this issue and warranty? I would have brought the car in for repair in the past if I knew there was a defect with the car. The car should be recalled.

ABS, Brake, Trac warning, and brake lights turned on. When I used a diagnostic device, I read the code C1391 code. The brakes of the vehicle are not working properly. Upon my research, I found that several factors can trigger the C1391 code, including a faulty brake accumulator pressure sensor, low brake fluid level, brake system leaks, issues with the ABS pump/motor, or electrical problems within the brake system. This problem has many safety implications. The brake system is fundamental for vehicle control and stopping power. Any compromise in its performance poses a risk to the driver, passengers, and others on the road. Prompt action is necessary to investigate and rectify the root cause of the C1391 code to ensure the continued safety of affected vehicles. I think Toyota company should issue a recall for this faulty system.

The rear right wheel broke off when going in reverse, leaving driveway (low speed). Towed to a garage. Was told that the rear frame member had rusted through. Had no warning of this -- car is used regularly and had been inspected several months ago. EXACT SAME THING HAPPENED TO ANOTHER COUPLE WE KNOW WHO ALSO OWN A 2013 PRIUS -- rear wheel came off because the frame member rusted through. Happened about a month before ours. They too were going in reverse, slowly, coming out of a parking spot, after driving 40+ miles to Boston. Car needed to be towed and rear frame member replaced. Repair for us cost $1300

While driving on the freeway, all of a sudden the ABS, Slip Indicator, Brake, and Brake System lights lit up on the dashboard. I immediately switched lanes to one that had no cars in front/back of me since I was going about 55mph. I tested the brakes since I saw the brake lights appear. It felt as though when the brake pedal was pushed, they didn't activate until you reached a certain point, almost to the point where the pedal needed to be fully pressed to stop. It didn't feel like the brakes were fully functional and behaving in the way they were prior to the lights appearing. I was afraid the brakes would give out. Then I noticed a whirling/hissing sound that was consistent. The sound was easier to hear when the car was at a complete stop but it could still be heard while driving. We took the car to a local Toyota dealership/service dept to get it evaluated. They diagnosed the car saying it needs immediate attention and is not safe for driving since it involves the brakes. The repair invoice stated VARIOUS BRAKE WARNING LIGHTS ON C1391.

Brake pump failed while on the highway. Brake functionality and braking distance changed drastically while driving high speeds. Dealer confirmed that the breaker pump and master cylinder must be replaced with a new assemblies. There was no recall for this failure, but a Toyota Customer Support Program for replacement of this brake assembly was active for reports of this failure only before April 2023. Toyota dealerships are not obligated to cover this replacement or make customer aware on any suspected vehicle unless the failure was present before April 2023. Warning lamps only appeared at brake pump failure - not before failure.
