Toyota Prius oil consumption problems

Toyota defective ABS system- revised master cylinder&brake booster pump never changed by dealership except misleading inspection and breach of recall in 2020. The incident happened last year in Sep 2024 dangerous on hwy or freeway. Thank got I was on the side street with beeping vehicle and codes on the dashboard, barely with serious risk went back home! As a defective parts they should be replaced for free or customer should received reimbursement! A professional dealer who performs ONLY AN INSPECTION for a “recall” in 2020 should replace the factory-damaged part and not brazenly wait for the codes to appear on the dashboard, depriving the customer of free replacement of the factory-defective ABS system. "the complaint was originally filed over the Toyota hybrid system problems in Feb. 2020, presenting claims on behalf of owners of certain 2010 through 2015 Toyota Prius and Prius PHV, 2012 through 2015 Toyota Prius V, 2012 -2014 Toyota Camry Hybrid and Toyota Avalon Hybrid vehicles that contain the defective braking system" ... This complaint accuses Toyota of placing PROFITS before the lives and safety of hundreds of thousands of drivers and passengers whose brakes are defective, but must wait for the potentially life-threatening brake booster defect to occur before the manufacturer will address it. The lawsuit ; ;"presents claims of breach of warranties, false advertisement, illegal sales practices, fraudulent concealment, unfair and deceptive trade practices, unjust enrichment and various other allegations on behalf of hundreds of thousands of impacted vehicle owners across the nation".

At around 1000,000 miles my Toyota Prius started burning oil like crazy. The dealer did an oil consumption test and confirmed the problem. I had to have my engine rebuilt because the rings were not seating properly. I had to bear all costs even though this is clearly a manufacturing default.

Excessive Oil consumption, particularly with highway driving. I have had this car for about a year. I only noticed that the oil was nearly empty when the engine was shaking while idling at an intersection. No warning lights for oil pressure or level ever came on, it would occasionally "ding" for oil pressure, but barley long enough for me to even read what the warning was. By excessive, I mean VERY excessive. First oil change after only 3k, almost empty. Road trip, mainly highway only about 600 miles, nearly empty. If I top it off, I check it constantly. City driving (more electric) it may burn a quart every 1-2k miles, highway more. I had the EGR, manifold and plugs serviced/replaced, it improved slightly. I'm having more work done now, but after reading SO MANY similar complaints online, I find it hard to believe this isn't a recall. An engine sputtering and nearly dying while idling is not safe, especially with no warning lights on! I contacted Toyota, they said they had not recalls or Consumer Confidence programs for complaints of oil consumption and/or piston ring seat problems in these vehicles (seems to be the primary cause). I did see a class action for many other Toyota 4cyl engines due to excess oil consumption.

Brake booster and brake booster pump assembly are faulty and failing. Brakes are still functioning, but will ultimately fail without warning, from what I have read. This is highly dangerous for myself and other motorists. I was driving last week and tried coming to a stop at an intersection. I pushed the brake pedal and the car hesitated and then jumped/lurched forward before coming to a complete stop. The brake booster is sounding every 30 to 45 seconds to try and build back the pressure it is losing. Toyota offered a "Customer Support Program" for these parts, as there's been numerous premature failures. Unfortunately, my vehicle no longer fits within the parameters of the support program (see attached). From what I've read though, Toyota has been negligent with replacing the brake booster under the support program. I have called Toyota Corporate and they have offered no reprieve and won't stand behind this faulty part. Toyota needs to be forced to recall these 3rd gen Priuses and ordered to replace the breaking system. Expecting customers to shell out between $2-3k to have the ability to safely break/stop their vehicle is ridiculous, especially when Toyota is more than aware of this issue. I was quoted $2600 over the phone to remedy the issue from an independent hybrid shop. I've owned 7 Toyotas and two have been Priuses. This 2011 is by far one of their worst to roll off the assembly line with numerous reports of breaking problems, oil consumption issues, and head gasket failures. They need to stand behind their product(s), especially to brand loyal customers.

Last year on September 13, 2021 I purchase a used 2010 Toyota Prius ( Vehicle VIN[XXX]) with 122414 miles on the Odometer, I got my oil changed on October 29, 2021 so I can keep track of when my oil is due. My odometer reading on oil change was 123,268. I drove 2806 miles, when I woke up on December 08, 2021 with no oil in my engine. I thought that was very strange so after adding a quart of oil My husband got for me. I took the vehicle back to the shop ( Good Year Tire & Rubber Company 1585- A Island Lane Fleming Island, FL 32003) I originally had my oil changed at, to have them check if there was some sort of leak. The odometer reading at that day/ service was 126,074. After a full inspection of the engine exterior componence, no leak was to be found. Then I decided to do some research only to find out that back in 2016 Toyota had a lawsuit against them for having manufacturer defects in the productions of engine between the years of 2006 - 2011. The manufacturer defect was the engine piston would eventually start having oil leaks into the engine causing engine excessive oil consumption. That same day I took my vehicle to the nearest Toyota dealership ( Coggin Toyota At the Avenues 11340 Philips Hwy Jacksonville FL32256) for a engine oil consumption test to be serviced on my vehicle. This process takes place by filling oil to the full line marking it... confirming there is no leaks....sealing everything and I was to return after driving 1200 miles ( odometer reading at service was 126,094). upon returning the vehicle on December 30, 2021...My vehicle failed the engine oil consumption test because after driving 1221 miles my engine was low on oil by 1.5 quart. This kind of engine oil consumption not only causes my engine to deuterate in time, but also my vehicle diminishes in value. After it was established that my vehicle engine consumes oil / failed the engine oil consumption test. Toyota advised me to get a new engine that would cost me $6987.63 INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATI

This vehicle has been burning oil for the past 10,000 miles. Vehicle has had all services and synthetic oil changes done from day 1 at the dealership. Oil changes every 5,000 miles since day 1. At 90,000 miles the car started burning oil excessively. Complaints and diagnostics were attempted at toyota franchise dealerships but they failed to find the issue. Finally at 100,000 miles the engine failed due to head gasket failure. This vehicle is classified as a partial zero emission vehicle and it is registered in a state that follows california air resource board regulations and is being serviced in a state that follows as well. Under the pzev regulations, toyota warranties emission related components for 15 years or 150,000 miles. Under toyotas warranty guide it states seals and gaskets are covered. The manual does not clarify any further leaving the coverage level vague and questionable. Upon trying to get toyota to replace the engine, they gave us a week of no responses and finally declining the claim even when the manual states it should be covered. The oil burning issue with this motor is a big problem that toyota has been trying to cover up. Toyota is quoting $13,000 for engine replacement. They have a service bulleting regarding the oil burning because it's a known issue, but they only honor claims under the 5 year 60,000 miles power train warranty.

I have experienced problems with the electrical, oil, and break systems ever since purchasing my certified pre-owned 2010 prius from the dealership in 2013. Toyota has never provided a satisfactory answer for what is actually wrong with the electrical system; the problem still remains. Toyota also does not have an ideal maintenance plan set up for the known increased oil consumption rate that is directly linked to my model vehicle and has not only not performed routine oil changes but also sent me home after a supposed oil change with zero oil in my tank. But today my main concern that I take issue with and that ive encountered from the get-go, has to do with the breaks. For years I've been telling toyota about how my breaks do this thing where under the right circumstances (those being things like slight bumps or raises in the road, or going over a manhole cover) the breaks not only give out but actually propel me forward with zero chance for stopping which is quite terrifying already and then when you add in other drivers on the road into the equation is a literal nightmare. Despite my many efforts for toyota to take a look at them they always refuse any service to them because my dashboard is not displaying any warning signs. Also, due to the fact that its not a constant issue, meaning it only happens under the right circumstances which idk where such a precise place exists near the dealership, they cant experience it for themselves. So my concerns are dismissed leaving me to fend for myself whenever these circumstances arise which no doubt an accident seems to be on the horizon. Then with ~114,700 miles on the odometer, my entire ABS system crashed while I was in traffic. Luckily I am a beyond exceptional driver and also have catlike reflexes so was able to manage my way to the shoulder of the road when this occurred. However, with warning lights now illuminated o

We noticed the red triangle light and so we checked the engine oil. The dip stick was dry. I put oil in the engine and the red triangle went away. I kept an eye on the oil level occasionally I needed to put more oil in the engine. 3 months after taking the car for a regular oil change at the toyota dealer the red triangle came up again and this time I spoke to the dealership about the issue. The response was that it would be expensive to repair the car and the best solution was to buy a new car. I was never told about the 2011 tsb for excess oil consumption that toyota had issued. Today, july 17th, 2020,I called the dealer to ask about the tsb, and I was told that the tsb has been out for 10 years so I had had until 2017 to qualify. I do not believe I ever received a letter notifying me about the issue. Had I received the notification I would been the first person in line at the dealership. Also, my steering wheel feels like it is loose, if the speed is over 45 MPH it feels unsafe, the slippery sensor light comes on when I am turning the wheel slightly on a dry road, and there is an excessive noise inside the car even with the windows closed. This happens during highway driving. I am about to donate the car so that it can be used for parts. I love the car now I know to check with the federal safety agency when I purchase my next car.
