2014 Toyota Prius V engine problems

Filed Jun 30, 2026 · Engine · TX

I purchased a 2014 Toyota Prius V in 2013, and it currently has 120,000 miles on it. Last month, the engine light came on, so I took it to a dealership. They diagnosed the issue and provided the codes P0302 and P0304. After consulting multiple shops, all confirmed that coolant is leaking into the engine, which means I either need to repair the head gasket or replace the engine entirely. The quotes I've received for this repair range from $5,000 to $15,000, while the current value of the car is only about $5,000. I want to file a complaint regarding Toyota's responsibility for these engine issues. We buy cars because we trust the brand, and in this case, Toyota has broken that trust. Despite maintaining the car according to Toyota's recommended schedule, I have encountered this serious problem.

The car began to jerk, made knocking noises, miss fires on cylinder 1, 2 and 4, coolant leakages, oil leakages, compression issues and the check engine light keeps turning on and off. My safety has been put into play because, the car would jerk many of times as it would want to stop as I was driving. I would then have to pull over and call for assistance. Per the Toyota service advisor he recommended that I needed a new rebuilt engine kit. The extended warranty company stated that I was negligent with my car and denied my claim and refused to pay for the 10 grand motor and I had to tow my car to another shop. However, the car at this time is still experiencing the same malfunctions. The warning lamps are still showing at this present time and prior to the failure of problem. This car meets the "Lemon law guidelines, However, I have been informed otherwise that I don't meet the criteria for lemon law due it being expired sometime last year in Oct of 2024.

The Head Gasket failed on my vehicle, and began to burn coolant and overheat my engine. Upon description of the issue, a dealership mechanic was able to diagnose the issue. The sudden failure of my vehicle due to overheating while driving was extremely risky, and I had no indication that the issue was a head gasket until a dealership mechanic was able to look at my vehicle after being towed. I had taken my vehicle to a third-party mechanic, and they could not tell me why my vehicle was burning coolant, but provided a temporary Stop-Leak fix that did not hold. The first appearance of the Check Engine light was about 9 months ago, was assumed to be the spark plugs, which I had replaced, but then my coolant light started coming on with the check engine light for about a week before the engine overheat incident. The vehicle has been inspected by a Toyota Hybird Mechanic. No other inspections have been done. My safety and other's safety was put at-risk as my steering, speed control, and speed monitoring systems immediately shut off once the system detected an overheat, making it difficult to pull over safely and slowly to address the issue/call a tow truck. I required physical assistance from another motorist to move my vehicle off the road to allow others to pass.

My car stalled while I was driving it on 2 separate occasions. It is a 2014 w less than 70K miles: 1/2022 Within seconds of 2 or more warning lights going on, the engine stalled. I was able to steer, brake and drive on the electric motor towards home. The electric motor drove another .5 mile before it also died, leaving me with no power steering or brakes. I was on a slight incline and coasted most of the way off road. The car was towed to our local dealer, which said the intake manifold had failed. Dealer replaced IM and related hoses and gaskets. 6/2022 I was driving on a busy interstate at high speed in the passing lane. The car started to lose power and decelerate. I maneuvered to the side of the road and UP! the on ramp. Made it to roadside business on remaining battery power.

Hi my name is [XXX]. Toyota headquarter case # [XXX] Incident day July 6, 2018 I had a big technical problem with my 2014 Toyota Prius V where it caught on fire because one of the valve lifters fell into the engine head and broke the engine block while driving. When that happened, the oil began to leak into the muffler and the engine and hybrid wiring immediately caught on fire. Many of my colleagues who also bought the same vehicle for Taxi business use in San Francisco all have a similar issue as mine. A few of theirs caught on fire, and a few others mentioned to me that the head gasket for their same Toyota vehicle blew out and each of them had to replace it at around 120,000 miles. I believe that’s why they don’t manufacture these same vehicles anymore because of the defectiveness in the engine. I opened a case with Toyota Manufacturer back in July 2018 and they sent a specialist to inspect the vehicle after the fire. He found the piece that fell inside the engine and that damaged the engine. The Toyota specialist admit to me that the engine of my 2014 Toyota vehicle is very defective and must be covered under warranty. My mechanic replaced the engine for me with a used one with 28,000 miles. This entire case was documented under my name with Toyota Motors Manufacture. I contacted the highway safety and I tried to file a claim against Toyota at the time, but I never got a follow up on my case after I left various messages. All they said was that they will investigate but never gave me any information regarding the engine fire situation or honor any warranty. I hope this incident will be investigated by your department and have this vehicle under recall. Thank you.

Unknown. I was basically driving on the freeway, when my car's engine suddenly stopped running. The car was automatically put into neutral and was not able to control the speed of the car, so I had to move to the side of the freeway. As I was sitting in the car, I started smelling burned wire and interior started to fill with smoke. I immediately turned the car off and got oit. As I was standing far away from the vehicle, fluid started leaking and it had caught into fire. The front bumper was completely burned off, as well as some of the engine and electrical parts were affected as well.

I am the first owner of this vehicle it has about 110k miles recently the started to shake when I start it in the morning or when parked for a while it started to show the check engine light some time it goes away on its own so I figured I will do 100k service changed the spark plugs oil filter etc. The shaking went away but after 1k miles the symptom came back with service engine soon and check engine when I scan it the code read p0301 I have also noticed the coolant is low went toyota picked up a coolant and added about a quart then the problem still persisted when I went online for an answer I was surprised by what I discovered most of the cars with the same problem needed an new or rebuild engine as long time toyota fan owned many different ones I was baffled by this problem I need help. As I learned online this problem affects most of gen 3 prius at this point I don't know what to do except ask toyota for repair or replacement of the engine as I just finished paying for it. The problem happens only when the engine is running at stop or driven at low speed I have also notice the average gas mileage suffers. When the car is accelerating the problem seems be unnoticeable.

I have 2014 prius v and the car was working fine with no problem at all. I got a recall from toyota that my car needs software update as a remedy for manufacturing problem. I took my prius to toyota dealer in new york city to perform the recall. The recall was done and the car problems started. The car was overheating now so I took it to a mechanic to find why,the mechanic said it was the water pump and changed it but the overheating was still there but was reduced. Later,the car was shaking badly at 15-20 MPH speed. I took it to the mechanic to check what's the problem,the mechanic shocked me with the news that the engine needs to be replaced because it is defective inside because of overheating of the car. Now I do not know what to do because I need a lot of money for the engine replacement. All my car problems have started after the recall done. Thank you

The head gasket in the engine failed at 200k miles and when starting the car in the morning the whole car hook and shuddered. The same problem happened to all my other prius v models at approximately 200k miles so I think this is a faulty gasket toyota has used in all its prius v model cars from 2012 to 2016 years therefore there should be a recall of these cars which toyota should fix without charge. I spent more than $4000 to fix the problem in each car. I have 21 prius v cabs at the moment most have already had the head gasket changed and thought I"m done with this problem and toyota should take the blame for this right now. I spent $30k to buy this car and after 2 years for it to fail on me that's messed up. Even though it's a commercial vehicle that still shouldn't be the problem.
