Dana Point, CA

FUEL/PROPULSION SYSTEM

8/2025 Car stalled on freeway. Went to dealer. They said nothing wrong. Then on a trip north, car stalled again on freeway. Went to the nearest dealer. They too said nothing wrong. This time same thing. There is a recall for the exact symptoms of the exact car yet they say the repair was done. Why does my vin not qualify for the exact symptoms that generated a recall? This was super dangerous at freeway speed. Toyota knows there is a problem with the inverter and it's computer. Now I'm paying again for a diagnosis. That makes $750 just diagnosing and now if they actually decide it is the inverter, I have to pay upwards of $3000 even though there is a recall? What the heck?

West Sacramento, CA

FUEL/PROPULSION SYSTEM

The car stalls randomly and does not enter fail-safe mode. The dealer says it is the transmission but the transmission has never shuddered or hesitated. I am reading that these vehicles have intelligent power modules in the hybrid inverter that fail and can cause stalling. I feel like the dealership is working with Toyota to avoid addressing the actual problem. In the meantime I was sent home in a vehicle that continues to stall randomly and does not enter fail-safe mode.

Escondido, CA

FUEL/PROPULSION SYSTEM

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. As stated this is a lemon car.

Grand Blanc, MI

FUEL/PROPULSION SYSTEM

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.

Santa Fe, NM

FUEL/PROPULSION SYSTEM

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.

FUEL/PROPULSION SYSTEM

THE CAR WOULD NOT ACCELERATE AS EXPECTED. IT BEHAVED AS IF THE FUEL INJECTOR WAS NOT WORKING PROPERLY. WE WERE NOT ABLE TO KEEP A CONSISTENT SPEED AND THE MOTOR STARTED TO HAVE A ROUGH IDLE SOUND. THE HYBRID SYSTEM STOPPED WORKING, THE ICON OF THE BATTERIES TURNED PURPLE AND WOULD NOT RECHARGE WHEN STOPPING. WE TOOK IT INTO THE DEALERSHIP, THE SERVICE PERSON THEY SAID IT WAS A SOFTWARE AND EMISSIONS MISS-FIRE ISSUE. IT WILL TAKE A PART TO BE REPLACED AND SOFTWARE UPDATED. TOYOTA SENT OUT A MEMO TO THEM STATING THIS MIGHT HAPPEN AND THIS IS HOW TO FIX IT. IT SEEMS SINCE THEY ARE WARNING SERVICE STAFF TO BE AWARE OF THIS THAT MAYBE THEY SHOULD TAKE CARE OF IT BEFORE IT HAPPENS AND NOT HAVE ME PAY OVER $900 AND THE STRESS OF IT HAPPENING ON THE FREEWAY AND THEN HAVING ME GET IT FIXED.

FUEL/PROPULSION SYSTEM

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.
