I bought my first used car, 2012 Toyota Prius, from Fowler Toyota back at the end of October 2023, but I was not able to pick it up until September 21, 2023 due to extra time for re-conditioning. I did not haggle about the price nor complained about the 3 week delay. In the last 3 weeks of owning my car, the TPMS sensor light and check engine light infrequently turned on. February 28, 2024 all the fault sensor lights on my instrument panel are on, along with the loss of proper braking function. I was not...

I was driving on the internet doing 60mph and there was a very loud bang and then a shaking of the parts under the hood. I was right next to an exit and coasted off the exit to a hotel parking lot. I had car towed to my mechanic. He said that the piston went thru the engine and the engine is done and needs replaced. I am having a hard time trusting Toyota again to purchase another Prius. I have had Prius for over 10 years and never had anything like this occur. I had no warning signs and no dashboard lights lit up until after all of this occurred and scared the life out of me then the engine light came on.

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.

There is no incident occurring to me .but I change some parts like head light.& whisper .engine .

Head gasket failure

the car was serviced regularly and for unknown reason the engine started running rough. I took it the mechanic and after completing a diagnostic test he said i have a blown had gasket in the engine. After reading online about the issue i discovered this year and model of toyota are notorious for having a blown head gasket issue. My mechanic recommended the engine be replaced. This is an expensive repair and toyota is denying any accountability about the issue

In September 2022, my car, a 2012 Toyota Prius V with 79, 056 miles, began making noises in the engine area and the brakes became loose, meaning it took more pressure on the brake pedal to engage the brakes. In November 2022 the following warning lamps on the dashboard came on: Master Warning Light, Brake System Warning Light and Warning Buzzer, Brake System Warning Light, ABS Warning Light and SLIP Indicator. I took it to the Toyota Dealership near me: Lipton Toyota in Ft. Lauderdale, FL, and they diagnosed car...

The engine caught fire while sitting in my garage. I had driven it for a few hours doing deliveries for a store and parked it in my garage around 2:30pm. About 1.5 hours later, my wife was coming home and opened the garage door and saw smoke above the hood of my car and then a few seconds later it burst into flames. I believe that it was smouldering for a while and the gust of wind when the big garage door opened gave it the extra push to ignite. The car was bought used and had a front end accident prior to my...

The contact owns a 2012 Toyota Prius V. The contact stated while driving 30 MPH, the vehicle stalled inadvertently. Several unknown warning lights were illuminated. Additionally, the brake pedal was depressed but failed to respond. The contact veered to the side of the road and intentionally struck the curb to stop the vehicle. The vehicle failed to restart. The contact stated that the vehicle later restarted and was driven to the dealer. The dealer diagnosed that the ABS actuator had failed and needed to be...

I am having issues with my Toyota I was never contacted NHTSA CAMPAIGN ID: 18V684000. My car has failed numerous times.

I was driving on the expressway and experienced a sudden loss of power. The internal combustion engine suddenly stopped and did not deliver any power to the wheels. I immediately received a message on the system that said 'Check Hybrid System Stop Vehicle in a Safe Place'. The electric motor still continued to provide some power with the available battery charge. I was able to make it to the shoulder of the road but it was challenging to get to the shoulder with no power or warning and high speed traffic. My wife...

Head gasket blow up at 175000 miles

There has been a safety recall on my vehicle for the years 2004-2009 models of the Toyota Prius, but my model year is 2012 and I have the exact same issue. 1) My check engine light comes on and off and it appears to be the hybrid electric water pump issue related to the coolant. The cap pops off and spills out. 2) When the light comes on, I am assuming the car is starting to overheat and is putting myself and my 3 year old daughter at risk as this is the primary car we use to transport her. We have just stop...

My toyota prius v only has 121,153 miles on it and during a short drive to work where we never reached speeds over 50mphs our prius v overheated causing a blown head gasket and all sorts of combustion issues. The repairs were $3000. This is a 2nd family car which has always been maintained by expert, license auto mechanics. This should never happen on a car with such low milage! I have learned that this is a common issues with this toyota prius model and toyota should file a recall and fix the overheating issues.

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.

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...

When idling there is a loud rattle and multiple random misfires in the engine. Appears to be a head gasket leak problem from reading forums. I have been to multiple repair shops they cannot determine the problem.

Abs , traction control,brake lights on. No power assist brake, no abs, no traction control

The abs brake pump experienced an "internal failure" at mileage of 113k. There is a customer service notice that covers 2012 toyota prius and prius plug in for the same issue regardless of mileage until 2019, and then up to 150k miles after that. However, my 2012 prius v was not covered. This abs brake pump just suddenly failed, there weren't any leading indicators. Toyota knows it supplied defective parts for the abs brake pump. There is already a lawsuit of other 2012 prius v owners complaining of the same. ...

It is having heavy miss fire which make the enging shaking too much many times

At about 100,000 miles the engine began using (burning) oil at the rate of about 1 quart every 1000 miles. Now at 150,000 miles the oil usage is 1 quart per 500 miles. The oil has been changed using the recommended lubricant more often than required since the car was new. Toyota is aware of the problem and has redesigned the pistons and rings but but offers no financial help for cars off warranty. The dealer estimated repair cost is over $5000.
