2016 TOYOTA PRIUS Complaints

Coolant is leaking. There were no indicator that coolant is low. Suddenly while trying to get on the freeway the car would not get up to speed regardless how much pressure was put on the pedals. On the way back home, all of a sudden the engine temperature light flashed on then off twice. The car operated like normal but it was still concerning and we had it checked out. Coolant was leaking but no where to be found? It seems Toyota had previous recalls where coolant was leaking into the engine. I think my model is also affected.

I reported issues with this car in 2018. Clicking sounds under the car which is still happening, peeling paint on exterior and inside door areas, substandard windshield that spread in a very unusual pattern when hit by a small rock. The NHTSA ID Number that was assigned to these complaints is [XXX] . None of these problems have been addressed. There are other owners that have experienced the same problems, apparently their issues have not been addressed. These problems should have been sent by you to the Toyota Corporation, but apparently was not. I have owned many Toyota vehicles and have not experienced these problems. I also own a 2012 Toyota Prius which I drive when I when I am traveling on the interstate, because I feel that the clicking noises on the 2016 Toyota Prius is a safety issue that seems to be coming from the steering section underneath the car. When traveling the speed limit on the on Interstate highways, what would be the outcome if the steering mechanisms underneath the car did not work properly. It is a shame that this safety issue has not been addressed by you, and it is also a shame that I have to drive my older toyota at these times to feel safer when driving.

We were driving kids to camp and the thermometer light went on. It was blinking for a while, then turned off and then turned steadily on. We weren't sure what to do, so we called our trusty mechanic who said "bring it in right now." We did and it turned out that this was a broken head gasket. Our car is regularly maintained by a trusted Prius mechanic and has less than 78K miles, despite its age. From our mechanic: We found the engine coolant was low in the radiator. We filled the system and pressure-tested, found no external leaks. The thermostat and fans operate normally. We found 54 ppm HCs in the radiator initially, and after a test-drive we re-checked and found 110 ppm HC in the radiator. Combustion chamber gas is getting into the cooling system, typically a symptom of headgasket failure. The cylinder head needs to be removed to evaluate. FYI this is the first headgasket failure we have seen on the 4th gen Prius, but it is the same engine designation as the 3rd gen Prius, which has a pattern problem of headgasket failure. The expectation is that the failure is the same, but we need to open the engine to evaluate. Given the low mileage, it might be worth pushing Toyota for a goodwill warranty even though it is out of the official powertrain warranty period. I called Toyota and they refused to pass along a goodwill warranty.

Driving on freeway my prius V started shaking violently from what appeared to be overheating of water pump failure or the coolant invertor pump. I believe this to be a known issue Toyota is aware of when I took my Prius into Camelback Toyota in Phoenix they said they could not recreate the issues. I know this was powertrain failure that could have caused me to crash on the freeway.

The contact owns a 2016 Toyota Prius equipped with Cooper Tires, Tire Line: Mastercraft, Tire Size: 195/65/15, DOT Number: (Not Available). The contacted stated that while driving approximately 65 MPH, the vehicle began to violently shake and vibrated. After stopping to inspect the vehicle, it was discovered that the passenger’s side rear tire had experienced sidewall steel belt separation. The cause of the failure was not determined. The local dealer and manufacturer were not notified of the failure. The failure mileage was approximately 20,000.

On September 2022 (at 46K) Dealer did TSB related fix on my 2016 Prius. PFA for service record. They replaced Exhaust Front Pipe, which is suggested work from Toyota PFA for Toyota Technical Bulletin. T-SB-0135-19 At 51,747 on March 1st 2023 around 8 40 am, while we are driving on highway at 70 mph suddenly Check Engine Light, Coolant light, Hybrid related lights were on Vehicle lost the control, speed was dropping luckily we could safely stop the vehicle on the shoulder no Vehicle hit us from behind. Sudden stop of engine while driving on highway at 51K miles is safety issue. Toyota dealer could not provide additional details except Engine is over heating.

The original windshield has a “rippling distortion” where the windshield has ripple/bubble from defective glass or installation mistakes, making seeing traffic signs or streets very hard. I just bought this vehicle and noticed the problem. It created poor road vision, especially at night. Toyota needs to recall and replace all these windshields before it causes more accidents due to poor visibility looking through the glass.

Shortly after having my Toyota serviced, I had an engine coolant warning sign appear. I checked and noted the coolant was gone. I bought coolant and filled the coolant tank. A week later, I see the light again. I have seen no leakage at all on the ground. I refilled the coolant and checked again the next morning. Again the tank is empty. I took the car to a local reputable service person and thus far, he sees no leakage outside of the car. This suggests to him a bigger problem, where the coolant is going somewhere it should not. If it is to the engine, I will have to replace that!!

At the beginning of this week, I was checking fluid levels and upon dropping my hood, I watched a crack in the windshield extend up from the base of the windshield. Then, while I was driving, I watched the crack extend and branch into a second crack. Upon further inspection, it appears cracking started under the windshield wiper and arched downward to the base of the windshield and another a new crack extend upward. I am the only person who drives this car. I do not park under a tree or anything that might fall on the windshield. I have not experienced any rocks hitting the windshield recently. I have not driven in the rain in several weeks. The only time the windshield wipers moved recently is when I cleaned my windshield over the weekend and lifted the wipers to reach underneath. Best as I can tell, the crack started due to the windshield wiper being picked up and let back down. This concerns me a great deal considering that is not a great amount of force.

When the battery cooling fan is running, the car is slow to accelerate or will not accelerate at all. The incident has happened multiple times over the past year when the temperatures are above 90. If at a complete stop, the car will not accelerate, it will only jerk forward. The car has to be turned off and restarted to be able to accelerate. If braking or reducing speed, the car will be sluggish, and I have not been able to get the speed over 40 mph. I have taken it to the dealership, but they said they could not recreate the issue, though I do not believe that they followed the directions I gave them to recreate the problem. No warning lights appear when the issue occurs, so they did not have an answer. The first time the incident occurred, I had just had the scheduled maintenance completed two days earlier and they did not find anything in the inspection that needed to be repaired. The first time the incident occurred, I was at a stop light trying to make a right turn. The incident has occurred twice when trying to pull on to the highway and accelerate up to speed.
