Car is burning excessive amounts of oil. Dealer told me (over phone) that triangle was from taking corners too fast (dealer has since said this was inaccurate info). Oil change for life (every 10K miles) at dealer and no one has ever notified me that car is using oil. 6,000 miles after last oil change, over 3 1/2 quarts of oil used. I nearly locked up the engine. Car is not leaking oil. Car sometimes smells of oil after starting. Toyota has extended warranty for certain models for this same problem, but not for Prius. My car has 117,000 miles and this problem has been going on for at least the last 25,000 miles (based upon orange warning triangle). According to dealer, problem is with rings (which is the recall for other Toyota cars). Also, according to dealer, this is a real problem for other Prius owners with 100,000+ miles. I consider this very dangerous to safe operation of vehicle and fumes from burnt oil.

Burning oil issue. Front head light short circuit or burned out. Leather seat separated twice.

I along with an alarming amount of others have experienced the 2010 Prius begin to burn oil at an alarmingly high rate around 60-80K miles. This is accompanied with an emission into the cabin of noxious fumes during high oil burn rate (heavier acceleration) moments. We have all been told by the dealerships that this is "normal". this has led to burning over a quart of oil every 1000 miles, headaches from the fumes, and now I have found out there is substantial soot buildup in the engine resulting from the oil burning requiring very costly repairs. Toyota refuses to do anything to help or even acknowledge the costly issue.

The contact owns a 2010 Toyota Prius. The contact stated that while driving at 70 mph, the vehicle stalled. The check engine and general warning lights illuminated. The contact coasted over to the side of the road. The vehicle was towed to a dealer where it was diagnosed that the water pump failed and needed to be replaced. The VIN was not included in the NHTSA campaign number: 12V536000 (engine and engine cooling, hybrid propulsion system). The manufacturer was notified of the failure. The approximate failure mileage was 92,000.

My Prius is burning an excessive amount of oil. More than a quart every 1000 miles.

- Fontana, CA, USA

My car is consuming about 1 quart of oil every thousand miles, sometimes even more. I have always got the oil replaced in a very timely manner and with only around 118,000 miles on it, this is very troubling. My dealership is aware of this problem and they have charged me upwards of $4,000 to replace the head gasket and the oil pan gasket saying it would solve the problem, which it didn't. they did the oil compression check with no sign of where the oil was going as there were no additional leaks according to them. They refuse to think this is a problem, which I think is a blatant lie. They know that this shouldn't be the case and want me to get the engine rebuilt for an additional $4,500, which is ridiculous for a car with such low mileage. I want Toyota to fix this problem now. I am very concerned about my safety as I have to constantly keep adding oil, which is wrong!

2010 Toyota Prius, 84,000 miles: Experienced loss of oil, took to dealer who topped off and asked me to return. Returned at 85,790 miles after further loss of oil (down two quarts). The Toyota mechanic had to call Toyota, who stated they knew of the problem. The PCV sticks open, resulting in oil being sprayed where it doesn't belong. Repair, which includes replacement of several parts, estimated at $629. The Toyota service tech was not confident the repair would not be needed again, and blamed use of ethanol in gasoline as the culprit. However, ethanol has been in use since well before this model was released on the market. Toyota knows it has a problem, but has not issued a recall.

On February 27, 2015, our house burned in the middle of the night while we were asleep. The fire started in the near vicinity of the right front headlight of the 2010 Toyota Prius. The car had been serviced just before the fire on February 25, 2015 at the local Toyota dealership. The car was off at the time and the key was not in the car at the time of the fire. While we were sleeping, the car evidently caught fire spontaneously at approximately 2 a.M. while it was parked in the garage. The garage door was closed. By the time we woke up, the garage was fully engulfed in flames. We were able to escape the fire. However, our house was too severely damaged (fire, smoke and water) after the fire to be livable, and it is currently being rebuilt. Our family of four (husband, wife and two children, 15 and almost 11 years old) is currently living in a rental house. We lost all three of our cars (the other cars were a Dodge durango and a Honda Accord) and a majority of our possessions. Damages are estimated to be likely in excess of $500,000 including house, cars, damage to landscaping, personal property, furniture, clothing, etc. Our homeowner's insurance is seeking a subrogation claim against Toyota for the expenses incurred regarding our claim. The Prius is scheduled to have a deconstructive exam soon with multiple parties present and is currently being held as evidence.

Excessive oil consumption, 2-3 qt per 5000 miles.

- San Diego, CA, USA

Waiting for reply from Toyota: Increased oil consumption past 100K miles normal for a 2010 Toyota Prius at 1 quart per 2000 miles? oil soot wiped from exhaust pipe. Yellow low oil warning light and beep sounds when making hard turns. On June 1, 2015 at 101131 miles, oil level was down 2 quarts and requested an oil change and filter from dealer. About 2000 miles later on June 26, 2015 at 103300 miles, 1 quart of 5-30 sae mobile 1 full synthetic oil for high mileage cars was added to top off.

Vehicle suddenly has excessive oil consumption at around 110000. Serviced at dealer since new, no leaks. Need to add oil every 1K miles. When service light came on, dipstick was dry.

- Gainesville, GA, USA

Serious oil consumption. Took it to three different Toyota dealerships and they all have said the oil consumption is within normal limits. Have to add oil every1000 miles. I never had to add oil to a car and this my third Toyota. The third dealership even told me to trade it in and get a new one. I have seen others complain about this on carcomplaints.com. Toyota should pay to repair the positions/engine.

- Kingsland, TX, USA

Burning oil 1 quart every 1000 miles. Oil consumption. Piston issue. Requires piston rings replacement. Smell burning oil in air vents. Cost of repair at $7,000 per Toyota. Toyota says oil consumption within normal limits. This is wrong. Request Toyota to repair vehicle and Toyota to pay for repairs.

I was driving approximately 35 mph and all of a sudden the car stalled and stated, "check hybrid system". stopped the car right away called my insurance company for emergency road service and had the car towed to a Toyota facility where they diagnosed the problem as a failed inverter, which is part of the hybrid system. This is a safety issue and must be addressed. If I had been on a freeway or in heavy traffic, I could see this being a very dangerous scenario.

On March 4th 2015 at 8:00 am, my wife was trying to change a parking spot into another about 50 feet away in the same church parking lot. She started the engine and the car was put on drive. Within a fraction of a second, the car accelerated beyond control. She could not steer or stop the car. The car jumped a curb, hit a light pool and landed on a grassy area. Tire marks reveal that the car experienced a sudden rush of acceleration beyond control 'unintended acceleration.' My wife is still under doctor's observation. The car front right; bumper, tire, fender, door, "a" pillar, and other parts were damaged. The car was towed to daytona Toyota and is still there since March 4th 2015. On March 6th 2015 a report was electronically filed with Toyota motor sales, U.S.a., Inc. On March 20th 2015, a "cdr" crash data retrieval was taken. The car has not been repaired. Even if the car is repairable, I would hesitate to drive it, let my wife drive it or with clear conscious sell it to any other human being. Please help us to mitigate the situation.

This has happened several times over the past two years. As I brake at low speeds, the car surges ahead as though your foot is on the accelerator. Sometimes it was so subtle, you wondered if it really happened. Today (11/23/14) there was absolutely no mistaking it. The car surged forward a couple of feet as I was slowing to turn left. If someone had been stopped in front of me, I would have hit them from behind.

Vehicle was being driven when a smell of smoke was detected. Upon stopping, smoke came from the engine compartment. Within 3 minutes the vehicle started on fire, extending to the roll up garage door. The fire burned the engine compartment, passenger area, garage door and siding before the fire department extinguished.

About a mile after having entered the freeway as I was merging towards the carpool lane the car shut off in the number three lane.the dashboard displayed the message, "check hybrid system", and would not respond. My speed was approximately 65 mph when this occurred. I immediately pressed on the brake but the car was not slowing down as it normally does. When I finally got over to the number 1 lane, I entered the emergency lane but was still having trouble coming to a stop. I brushed up against the freeway wall in order to come to a complete stop. After switching the car off and attempting to restart it, I would get no respond and all the dashboard indicators would remain on with the "check hybrid system" displayed. This incident was terrifying as I was driving with my two year old daughter and two other occupants. The car should have displayed a warning and not simply stalled out. If this incident had taken place a few minutes later, I would have been in the hov lane and could have resulted in a devastating accident.
