11 problems related to power train have been reported for the 2014 Toyota Prius. The most recently reported issues are listed below.
Brake failure / unintended acceleration / unknown cause driving at approx 25mph on urban street (road in good condition no potholes, ramps, etc) I began to slowly brake as I approached a red traffic light. Instead of braking, the car began to accelerate quickly. I pressed the brake pedal again - no response. Pressed down hard for a third time which executed an emergency stop. This all happened within 1 or 2 secs. There were no injuries or involvement of other cars on this occasion. However, had I been any closer to the car in front, I believe I would have rear-ended it. Had this occurred a few moments later, at the busy junction 400m ahead, it could have been fatal. I am absolutely sure it was not driver error. I was not distracted, drive regularly, and have been a confident and safe driver for over 30yrs. I have never experienced this in a car before, and in fact wasn't aware that it could happen until I researched it on this site. No warning lights or indicators came on. The car ran normally for the remaining 2 miles back home. I didn't think anything of it before, but prior to this incident (in our 7 yrs ownership) there were approx. 5 instances when the engine would "roar" as if it wanted to accelerate but didn't when I was breaking or slowing down on a highway. Also, there were perhaps 3 instances when the car felt as though it was "running away" I. E. A slight acceleration - for no obvious reason. As neither of these represented safety issues, I assumed the car was just a bit old and these issues would be addressed as part of any service. Now I wonder if they are related to the sudden acceleration. The car is currently having a "health checks" run, but nothing has been found. I am reluctant to drive this vehicle if neither my dealer or Toyota can discern the problem. Overall we have been happy with this car and its performance, but this is an unacceptable "anomaly" as far as safety is concerned. Vehicle available for inspection.
Rattle type of noise can hear and feel from driver's side in front suspension area while driving lower speed and when push brake and stop . Most of noise happened when push brake to stop and slowly start driving / moving vehicle again . Thought noise is from suspension but after being full inspection on vehicle , mechanics believe it's noise from " hybrid system power inverter " . Search recall states on nhsta web and found recall is " incomplete " . So am planing to bring it and ask at Toyota dealer in culver city CA where I originally purchased vehicle for repair / replace inverter . It supposed to be perform as free of service .
Tl- the contact owns a 2014 Toyota Prius. The contact stated that while her wife was driving the vehicle at an unknown speed, the vehicle began to make weird noises and the vehicle began to stall. All the engine warning lights flashed on the vehicle as the the failure occurred. The contact's wife pulled the vehicle over and restarted the vehicle. Once she was able to restart the vehicle, she was able to drive the vehicle to a dealer(fred anderson Toyota of columbia 2136 sunset blvd, west columbia, SC 29169 803-223-7265). Once at the dealer, the contact was informed that the hybrid module failed and was given a quote of $2,200. 00 for the repairs. Upon investigation, the contact discovered that there had been recall on previous make and model vehicles from 2010-2013 under NHTSA campaign number: 18v684000(hybrid propulsion system). The manufacturer was notified of the failure and informed her that her vehicle was not under recall and offered no further assistance. The contact was informed to contact NHTSA for further assistance. The vehicle had not been repaired. The failure mileage was 148,000. Jo.
Vehicle stall . Show �check hybrid system � stop the vehicle in a safe place� dealer said probably inverter ipm failed.
Toyota issued safety recalls e0e and f0r for the failure of the hybrid inverter. If the inverter had not failed yet, the Toyota's remedy is a �software re-flash�. The software reflash �remedy� is not sufficient. There have been an excessive number of inverter failures after the software re-flash �remedy� for these recalls has been completed. This is very dangerous to drivers, as it leads to unintended deceleration � the Prius spontaneously entering �limp-home mode� or even a �hybrid system shut down�. This is dangerous as in results in drastic reductions, if not the complete loss, of power. These unintended deceleration occurrences predominantly happen while the vehicles are in motion � many times at high speeds. Between only two dealerships, we have documented approximately 100 inverter failures after the e0e and f0r software reflash �remedy� has been completed. During one inverter failure, which took place after receiving the e0e software re-flash, excessive heat was generated within the inverter that melted steel bolts and created an electrical arc that blasted two holes through the aluminum case of the inverter assembly. The driver stated if she had experienced this failure while on the freeway, �she wouldn't be here anymore. � the vehicle was a 2012 model year and at the time of the failure it had only 31,222 miles on it. Instances of unintended deceleration will continue to grow daily until Toyota implements a sufficient remedy that will prevent these losses of power from occurring. Attached please find a report detailing, for only two dealerships, the inverter failures we've experienced after the e0e and f0r software re-flash remedies have been completed. Also attached, please find the photographs of the inverter which experienced the electrical arc. Please consider that "date this happened" as the filing date of this report.
I purchased this car used, in may 2017 with 14,500 miles. I am having an intermittent problem of the car shifting back into reverse when I am trying to shift from reverse to drive. It has happened approximately a dozen times since in 5 weeks. I have brought it to the dealership where I purchased the car 3 times. They are currently keeping the car overnight. They have not been able to duplicate the problem, as it is intermittent, and do not get any codes when they've checked the car. The are suggesting it is a "driver error". It does not seem to make a difference if it is hot or cold, on a slope or flat surface, or if the car has been sitting idle for some time, or having been driven a long distance. It has happened in every such situation.
After parked for 20 minutes, the car is dead, had to jump start. Battery was replaced by the dealer, but the issue was not taking care of. At least 3 more times since the battery replacement, I found my car was again ded after parking, can not even open the door with remote. But all 3 times the car was able to power on after a few minutes on it's own while waiting for tow. . . Above that, the clock, trip odometer and temp settings were resetting on random times since 650 miles, as well as the radio which will turn on and off at random. Dealer replaced the radio but it still does the same. I was told that they (dealer) can't tell anything wrong with the car, and can't do anything about it, unless it's dead while it's in their shop, even after I showed them the photos and videos of the issues.
I puled out on the road & the it died. It a little bit it stared up. The same thing happened last summer.
The contact owns a 2014 Prius. The contact stated that vehicle intermittently shifted into neutral. The contact mentioned that the drive and/or reverse gear needed to be held in order for the gear not to shift into neutral. The vehicle was taken to the dealer where the failure was not determined. The vehicle was not repaired. The VIN was not available. The failure mileage was 20,000.
Acceleration driving east on us rte. 50 at about 60 mph: vehicle accelerated for no apparent reason. I nearly ran into the car ahead of me. This car is equipped with radar adaptive cruise control, which was engaged at the time. I turned off the cruise control in time to avoid a collision. Unintended acceleration has sporadically occurred, but it is usually fairly mild. This time it was so powerful that it felt like I had stomped on the accelerator; the engine roared and the car took off at full throttle. Thankfully I was traveling at the max distance of the cruise control. Acceleration was not caused by floor mats. I watched while the dealer service manager checked. Deceleration driving east on I-the car ahead of me signaled to exit the interstate and turned smoothly onto the exit ramp. As soon as he was out of my lane my car's cruise control locked on to the that of the exiting car and vigorously applied the brakes. Stepping on the accelerator did no good.
Tl-the contact owns a 2014 Honda Prius. The contact stated that when the gear shift was in drive the vehicle reversed. No warnings illuminated on the instrument panel. The vehicle was not taken to a dealer or independent mechanic. The manufacturer was not made aware of the failure. The failure mileage was 3,000 and the current mileage was 3,002. Sr.
