Gas Recirculation Valve (egr Valve) Problems of Toyota Prius

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.

Had blown gasket repair last year (which was fixed by my local Toyota dealership and all cost paid for by myself). Dealership acknowledged that there were known issues with failures due to clogged egr's and out-dated manifolds. Was never recalled and did not know about the issue until after the incident. Wanted to report issues since it appears countless other have been in the same situation with gen 3 Prius. Toyota needs to be offering egr cleanings and updated manifolds at no cost and reimbursing customer's for previous repairs.

The air temperature was probably about 50 or 60 f. On a route I routinely drive , I accelerated up hill normally from 0mph to about 45 to 55 mph. I did not accelerate aggressively. Just after climbing the short hill, the engine suddenly loses all power. I had to pull over. I look under the engine to find five pieces of metal blown out of the bottom of the engine block above the oil pan and oil spilling out onto the ground. The car has about 98,000 miles on it and was maintenance regularly including on schedule oil changes, coolant change, state inspections. There were no check engine lights or electronic error codes to indicate anything was wrong with the vehicle which I would have been able to diagnose and possibly fix. The car had been maintenanced in August/September for winter by myself. On the last maintenance, oil was discovered inside the engine air manifold and throttle body that had to be cleaned out and (the egr was also moderately carbon clogged). I'm very dissatisfied with how Toyota handled my case. They called twice to ask when I wanted to schedule my next service appointment when they had the car sitting on their parking lot for three months. I also wrote them a detailed email similar to this report asking how Toyota could help and that I could not afford to buy another car. The engine failed and it can be inspected upon request. The vehicle had complete loss of power. The vehicle was towed to the nearest dealer. I have seen videos on youtube. Com that show other people replacing blown Prius engines and head gaskets. You would see chunks of metal missing from the engine block. The vehicle was not inspected by the manufacturer police or insurance. I could have been hit by another car from behind especially if the hill were longer like on a mountain side or some other situation. Separate issue: mice enter the two rear ventilation openings to nest in the car. Mice chewed on of the oxygen sensor wires to cause an electrical fault.

Loss of power, engine rattle at start. Toyota dealer inspected and said the head gasket is compromised. We have always take care and regular maintenance on the vehicle. I found out that Toyota has a fault egr system that is the source of the compromise. Toyota never notified us.

The check engine light is on; the car has stalled and looses power it needs to have the sticky exhaust gas recirculation valve taken care of. It also needs psv coverage for brake booster and brake booster pump assembly safety warrantee enhancement.

My Prius v recently started to have some issues with coolant loss and loss of performance. My onboard monitoring system (hum by verizon) warned me I have a misfire on cylinder 2. I replaced the spark plugs ( denso plugs) and checked all the coils. I also checked and cleaned the egr valve. This made no difference. Upon start up, there is a loud knocking noise and I have water periodically coming out of the tailpipe. I have taken my car to a reputable shop that specializes in asian cars and it has been diagnosed with a blown head gasket at 165,000 miles. Thats a very costly repair! I have looked at Prius forums and seems like this is not unusual for this year model. According to to people that are on this forum, Toyota has since corrected this problem. If this is true, shouldn't Toyota be responsible for damages? as a consumer and working man, is it fair that I bought this vehicle in good faith because of Toyotas reputation, only to find out that I have been deceived because they have been aware of this problem?.

Engine -engine have broken head gasket. Coolant reservoir started to drain. Coolant slowly leaks in internal combustion engine due to broken head gasket. Causing shaking engine because coolant cannot combust inside the engine. -also egr cooler was fully clogged by carbon that caused failure of carbon air circulation. Brake slowly failing brake actuator in the process. When pressing brakes, whining sound is present and brakes slowly fails to hold pressure in the system when brakes are applied. -brake system was fully inspected and no leaks were found and brake fluid holds in full level.

1)intermittent regen braking failure causing brakes to become more difficult to press thus harder to stop the car in a timely manner. Usually when there is stop and go driving will the regenerative braking fail. 2) clogged egr valve causing a loud engine knock resulting in a blown head gasket.

Typically the key is left in the car in the garage. Tonight at 6 pm, at a garage temperature of 83 degrees f, the engine spontaneously started. No one was in the car and it had been garaged for about 3 hours. I just happened to be in the garage when the Prius started and was nothing short of flabbergasted.

Engine oil getting to the intake manifold. And filling up with oil. Throttle body gets really dirty with oil. In turn the engine burns oil. Which clogs up the egr system. The engine would over heat which could cause the head gasket to blow. During winter months. Engine restarts would be harsh because it would have condesaion on the cyclinder this could cause the engine to blow. Broken connecting rods. Blown head gasket all sort of things could happen from having oil get to the intake manifold. Starting from 2010 these Prius suffer from this and Toyota hasnt done anything other then suppsodelly redesigning the intake manifold. Which is the same. Toyota just dont want to deal with it.

Our 2008 Prius experienced engine failure while driving CA. 70 mph on a day when the temperature was between 90 and 95 degrees. This appears to be the same problem with the inverter that has happened on later models, especially as �high thermal stress� featured in reports of those. Two mechanics were unable to pull a computer code on it and said they couldn't offer an opinion unless it was replicated. Each mentioned the inverter problem, but claimed that it could only have happened on model years more recent than ours. A Toyota company rep claimed never to have heard of it happening on any car before 2010. I asked if there were a database of such issues she could check to see if other owners had anything similar happen before 2010, but she declined to do so. I believe she claimed that the company maintained no such database. All I remember for sure is that she projected no inclination to follow up, appearing to treat it as a one-off problem that didn't merit further attention. This happened while I was passing a truck, with a car close behind clearly intending to pass me after I had gotten around the truck. I suddenly realized that I had no acceleration and that the dash lights had come on. I was luckily able to steer across the driving lane to the right shoulder without being hit as my speed dropped. I tried starting the car again; it started up as if nothing had happened so we continued, carefully, on our way. That specific problem has not reoccurred, although there were two incidents (one earlier that day and one the day before) when pushing �start� failed to start the engine. Dash lights and air conditioner fan came on, but engine did not start until the �start� button had been pushed twice more. In both of these cases the temperature was also in the 90s.

On October 31, my wife and son were in the car approaching a parking space after completing a 360 degree turn into the parking space. Car suddenly accelerated and jumped a 7" high curb blowing out the right front tire and damaging the right rear tire. Car was towed to the team Toyota in glen mills who told me to notify Toyota of the incident. Toyota called me on November 2 and given a complete detailed account of the incident. On November 3, Toyota sent an authorization form to download the edr data which was returned along with diagrams of the incident. On November 4, bosch contacted me requesting the information already sent to Toyota which was sent to them. On November 22, the bosch representative went to the dealership and downloaded the edr data. On 11/26/16 - received report from eaa engineering analysis. Indicates that the car accelerated from 2. 5 mph to 7. 5 mph in 1. 8 sec. Accelerator depressed to 100% and at 98% at impact. There was no post crash information in the report . I have called Toyota three times since receiving the report and have not been able to speak with the case manager nor the claims department to date. They indicate that I won't hear anything until January 5. In the meantime I am driving a rental car.

Engine shut off at approximately 8500 feet above sea level (carson pass, highway 88). Driving approximately 35-40mph. Clear day 70 degrees. No warning light for overheating, but aux fan turned on in rear seat. . Towed car approximately 50 miles to carson city. Inspected by Toyota dealer in consultation with Toyota service consultants. Replaced hybrid control ecu. No charge to me and Toyota reimbursed for 2 days expenses. Trip home , aux fan turned on at 8500 feet remained on until approx. 7000 feet elevation. Consulted Toyota, referred me to Toyota dealer near home. They consulted with Toyota hq. Hq recommend another test costing $500. Dealer could find no fault. I asked Toyota for reimbursement of $500 and to investigate engine shut off as a potentially very dangerous situation. Toyota referred me back to local dealer. Maintenance manager there told me they had already performed tests:nothing more to be done. Have not heard back from Toyota about reimbursement or further evaluation of the problem.

Fire and total loss of 2005 Toyota Prius, 19,300 miles after returning from work, the vehicle was parked as usual with engine power cut in the owner's driveway. A few minutes later, smoke was noticed inside the car with flames showing from underneath the vehicle. The fire department extinguished the fire about 10 minutes after it was first noticed. The main damage is in the rear left (driver's side) of the vehicle, with the cargo compartment completely destroyed, tire completely melted, all plastic in the area melted, door blackened, the rear bench destroyed, the ceiling carpet destroyed and big heat marks on the roof of the car. The vehicle was not modified as a "plug-in hybrid" which have been reported in at least one incident of fire. The external temperature was moderate, around 70-75 degrees. Updated 06/05/jb.

Nothing special or extraordinary led up to this failure. I was driving to work at about 7:00am. The temperature outside was about 70 degrees and the car is kept in a garage every evening. In the middle of acceleration (I was going about 25mph), the car stalled and the "red triangle of death" came up on the dash, along with several warning lights. The navigation system also provided the word "problem" and a little, red car symbol with an exclamation point in the middle of it when this happened. I was able to drive to an apartment complex under battery power only. I then shut the car off, waited a few seconds, and then started it again. The engine did kick back in after this, but the warning symbol (little, red car) on the navigation system didn't go away. I took the car to my Toyota dealership and they said that they had to "recalibrate the engine computer. " the car is now running as normal. The car is a 2004 Toyota Prius. My worry with this is what if this would have happened while driving across kansas, while 80 miles away from anyone to help you? the battery power surely wouldn't be enough to get you to safety. This is a problem inherent in the software of the engine computer and it should be fixed for all owners.

The Prius shut down, stopped using gasoline power, while I was in the passing lane and traveling 70 miles per hour in moderate traffic on interstate 40 in nashville, TN. The red triangle, check engine, vsc and a few other warning signals illuminated. I managed to avoid being rear-ended , pulled to the side of the road using battery power, shut the battery power off, and consulted the owner's manual. Approximately 10-15 minutes prior, the add fuel light illuminated and the fuel indicator displayed a single bar. Having driven the vehicle for the past 8300 miles, my wife informed me that we had about 2 gallons of gas, and could easily travel another fifty miles. The temperature was near 90 degrees. I started the vehicle and chose to drive it off the interstate. We traveled 2. 5 miles and coasted to the side of the road as the battery depleted. I managed to slowly drive the vehicle to a gas station and refueled. The fuel tank could only accommodate 8. 1 gallons of fuel; it holds 11. 7. Once refueled, the warning signals disappeared after 30 seconds, and we drove home. My wife took the car to the dealer, joe heitz Toyota in clarksville, TN, the next day for an evaluation. The mechanic said that the computer indicated that the vehicle ran out of fuel. Since there obviously was fuel in the tank, I pressed the service manager for answers. By the end of the day and after consulting with Prius technical folks in California, the service manager said that the fuel bladder may have collapsed over the sending module thereby signaling the car's computer that it was out of gas, which caused it to shut down. He said Toyota is looking into the problem and provided a lame solution; refuel the vehicle before it gets too low. This is an unacceptable answer and I implore the NHTSA to investigate this potentially deadly anomaly. It is only a matter of time before someone is in a fatal accident because the vehicle shuts down while traveling at interstate speeds.
