2014 Toyota Prius V: check engine light

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.

ABS Brake pump actuator booster failed. It is available for inspection. While driving, I started hearing a hissing sound from my brakes. I tried to slow down and my several diagnostic lights (ABS, traction control, brake, check engine, etc.) flashed on while my brakes failed to work properly. I turned on my hazard lights immediately. I was in the middle of the road with my toddler in the car and I almost rammed into the car in front of me. Luckily I was able to pull into a turn lane and pushed with all my might on the brakes and it finally was able to stop. My brakes failed and I could have hit the cars in front of me and hurt my child, myself and others. It was terrifying. Problem has been confirmed by an independent service center. The warning lamps only appeared WHILE the issue was happening and my brakes failed to work properly.

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.

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.

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.

The check engine light came on 11 months after it had previously come on and supposedly fixed (april 2017). Now I am told it is an evap problem again ( evap pump and purge flow valve weakness). The recommendation is replacement. A internet search revealed that this same problem in australia caused a recall. This is a $950.00 replacement and my vehicle has only 57700 miles. This is shameful.
