In motion while accelerating past a slower car. Heard and felt a pronounced thump and lost engine power on busy local thoroughfare. Moved to a turn lane and stopped. Multiple dashboard lights and "check hybrid system" on led display. Power off car, and back on twice and got the same error on display. Found that car could move on ev power and I got it into a safer location at an adjacent parking lot. Had vehicle towed to repair facility. As a driver this was disconcerting as I could not clearly determine if the car was at all driveable. If a driver were to stop immediately in the same situation they would be on the roadway. If I had not pressed on the accelerator pedal after powering on the car again I would not have known I could move the car to a safer location. Display should read "hybrid system failure" then "limited ev power available" then "move to safe area if necessary" cause: Hybrid inverter failure. Repaired by Toyota under 2014 eoe and new 10/2018 recall J0A

Prius 4-cyl

  • 150,000 miles
At approximately 120,000 miles we started receiving messages from our dealership that the car was starting to use oil even though we have performed all required maintenance and on time. Then between 130,000 and 140,000 we starting getting an oil light that would come on during cornering. We were told to keep a gallon of oil with us and fill it between changes and we did. It would use about 1 to 2 quarts between changes. Then at 150,000 the engine blew up. It was within the time limits of the warranty but not the mileage so Toyota would not help us out on a new motor. After that I researched on line and others are having similar problems. Most if not all our miles were highway cruising miles so easy miles. We drove this thing like a baby. We have owned many other vehicles to well over 250,000 so this is not a case of we don't take care of our vehicles. The motor right before it blew was making a loud screeching noise but no lights on the dash to indicate that anything was wrong.

I've had my Prius from 4-14 to the present 2016. I keep having issues with the dealership I take it to for repairs. [xxx] in la crescenta ca. After mentioning and describing issues, the staff there says that unless the dash lights up with a message and gives a code, they cant fix it. So in order for them to look into it any further than me telling them dash light is nec. I've told them about the ac noise from the first say I took the car in to get services at 33K. They say they don't hear or see anything. My ac compressor sounds like its going to explode when ac is on. Brakes have been extremely diff. To explain because of terminology. They seem to lose their power when being pressed and ABS seems to malfunction?? so they drive it and tell me its nothing I need to worry about and will be fixed when changed. Change brakes and the prob persists. Not only ABS but Firestone says my hardware has issues as well. I bring it to the attention of the staff and nothing seems to get done about it... my odo. Speedom is/was off +2 mph. My weather seals have been stripped and ripped off the vehicle which now causes water leaks from every crevice.. and the biggest two of all my complaints are 1- hybrid batt. Fan never worked and I wasn't told...hyb batt has never worked properly (drains way too fast when stopped at a light or in traff) along with the heat created by the batt and the engine that fill up the cabin and will have the temp raised upwards of 90+ on a 75 deg day. 2- the ECU's ipm's (or something like that) has not been calib. Or updated. Even received coverage stickers from toy headquarters stating full coverage if a.B.C. (listing of problems or malfunctions) I describe the exact same symptoms to them and get the same response"no code, no fix" help and ps I just checked the VIN online 4my veh & it says a diff package w/a bunch of extras that I never got upon purchase"??_hmmm?" information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

"takata recall" this is our first Toyota purchase and we are extremely let down with the fact that it is losing an excessive amount of oil. This is a safety issue. In the event that the engine may cease if it runs out of oil. We previously have only had american vehicles, and were told that Toyota is a much better product.. well as of this past April, we had this brief light go on. It doesn't stay on very long and only appears when you turn a curve. Then the "oil maintenance due" light appeared. That's odd, because I just had my oil change done 2 months ago! I went to a local oil service station immediately and found out I was down to only one quart of oil in my engine. I've never had this happen before! they looked for a leak and didn't find one. They topped off the oil and I was free to go. Well, the same scenario happened again in July, only 3 months after the last top off. I made an appointment with the dealer to have him look it over. They said it needed a system engine cleaning, there were no leaks, they gave it an oil change, and the spark plugs looked fine.. $300 for this to be done. Then they told me to bring it back in 1900 miles... well this seemed to work... until... now.. in October/November (2-3 mos later) the same issue happened, and now they are telling me I need a new engine that will cost anywhere from $3000 to $5800. I have only had this car going on 5 years. I have never had to replace an engine on any car before.. where is the Toyota quality we were told Toyota stands behind"?"

Request help with 2011 Toyota Prius oil consumption, quality, safety, & air pollution issues: I bought the car new. Just after 100,000 miles I noticed it was using oil between oil changes. It has gotten way worse to now at 145,000 miles it used 3 qts in 2000 miles. It does not warn you that the oil level is low until you are 3.5 qts low & a messages says you have low oil pressure. This is unsafe in that the car could go dry on oil and the engine sieze up. There is a tsb on this for other Toyota vehicles, but not yet Prius. I believe Prius needs to be added to the list & I want Toyota to replace my engine or at least the piston rings. So far Toyota is not admitting to oil consumption problems with the Prius. This is also a possible emissions issue. I contacted Toyota's customer experience center in Feb 2016 and they set-up case no. 1602170764 to track my complaint. They referred me to alamo Toyota in san antonio. I do not believe that Toyota is being proactive in addressing this problem. After researching this issue on line, I have found many other Toyota Prius owners with the same problem. The problem does not show up until you are close to the 80,000-100,000 miles point and so for those folks that drive less, the problem may not show up for another couple of years. I thank you in advance for any help that you can provide to me. I spent over $23,000 for this car and hoped it would give me trouble-free transportation for more than 4 years and 100,000 miles.

Prius started consuming oil around the 105,000 mile mark. Two months ago, I took it to the dealer and they had me come back after 1100 miles after my oil change. They said it was consuming oil because the piston rings were leaking. The lady tried to sell me a used engine for 3,000 or 5,000 dollars. I told her that is why I bought Toyota because I didn't want to spend money after 100,000 miles. I have looked online and this practically happening to all the 2010-2011 prii. My buddy owns and Camry and just had his block/piston rings changed for the same problem. This morning, I am a 100 miles from the need of an oil change, and when apply the breaks I get a yellow light coming on saying "not enough oil pressure". I google this and people are saying it is because my oil is low again. I think Toyota is trying to avoid having to recall this.

This car consumes oil... it dose not leak the oil and the dealer says that one quart in 1200 miles is normal... this oil is polluting the atmosphere and is expensive. I fi was told that it would consume this much oil at 100K, I would not have purchased the car.

Found out the violent engine shaking and the mystery loss of coolant without any noticeable leaks is due to a leaking head gasket that his common to many owners. Car now runs rough and mileage is affected. Many other owners reporting the same issue priuschat.com/threads/new-service-bulletin-for-engine-knocking-at-startup-T-sb-0012-10.102200/page-40

On start up in cold weather, <40*, after several days of not being used, the engine rattles like there's a loose engine mount. It lasts several seconds, then stops. After the engine warms up it's fine. This happened several years ago and I had tsb-0204-11 installed at 38,000 miles (12/18/13) and had no problem the problem reoccurred yesterday, 1/3/16, 76,000 mi, and I'll check with my mechanic for codes.

There are 3 issues I am having with this Prius. The brakes are the first problem. As others have stated, I too have the same lurching forward when braking over bumby or rough roads. This has been ongoing over the last few years. Second, the suspension is creaking and crunching when making turns at low speeds under 20mph. This happens when the wheels are turned all the way right and all the way left. This crunching noise happens when backing out of the driveway, making U-turns, coming to a stop on an incline, and braking over speed bumps. I've had the dealer look at this for the last year when I come in for service and one tech says they can't figure it out, another tech says he hears it but can't find the root of the problem, the service mgr. Also went on a drive with me and reproduces the noise concern but the techs couldn't find it. Most were suggesting new front suspension components-struts, towers, links, etc. I replaced the two front struts and all of the extra components-the noise concern is still there. I am very upset about this. Third issue is the ice-motor. When stopped at a red light and the engine shuts off, the car lurches forward and makes a creaking sound. It's appears that something is not right. The engine seems like it is loose. The engine also makes rattling sound when cruising lightly at 15-25 mph with the accelerator pressed slightly. The sound is coming from the passenger side, under the dashboard-glove compartment area. This is a rattle sound coming from the engine. I've had this looked at as well and the dealer states they cannot duplicate it. I have recorded all sounds related to these concerns and am taking it back to the dealer this month.
