2013 TOYOTA PRIUS Electrical System Problems

The hybrid braking systems on Toyota Prius' manufactured from 2010-2015 had a serious failure of the hybrid braking system that had additional long term warranties to repair, but never recalled in order to save the money from a total recall. The Sloan Toyota dealership in Glenside knew before I purchased the 2013 Toyota Prius I purchased that a serious brake system failure was very probable with my car but failed to tell me. If they did, i would not have purchased the car. I had the 5000 mile oil change in early August and three days later after the service and a clear 25 point inspection, and the system failed. I want full reimbursement or just pay for the repair.

Around May 2025, the brake booster and pump in the car stopped working. There was no clear warning lamp or indicator prior to it failing. While driving on the highway, the part stopped working and significantly changed the car's braking power. Rather than smoothly braking as it did before, the car's brakes have significantly less braking power. The defective part also affects the car's ABS system, making the car unsafe if a sudden stop were required as the brakes will lock up and the car will lose grip on the road and start skidding. Significantly longer braking distances is needed and it's not clear the car would be able to safely stop at a short distance in the event of an emergency. It's a miracle we didn't get into any accidents when the part suddenly failed. There is a significant risk that failure of this part will be the cause of a car accident when the car suddenly no longer brakes how the driver is used to. Toyota has previously offered an extended warranty on the part, but the part did not fail until shortly after the warranty expired. The car has been within my family since it was originally put into service and none of the owners were ever notified that the part could be replaced or even fail in such a manner. The problem has been confirmed by a dealer but they have only offered to fix it at a significant cost. The vehicle does not feel safe to drive. Warning lights only appeared after the part failed but they weren't particularly helpful in diagnosing the problem in the moment because 4 different lights turned on all at once.

While driving on Highway 316E on March 31, 2022, at approximately 10am, at some point, as traffic started to slow down and I applied my brakes I was dumbfounded when my car would not stop! It was frightening, as I watched my car get closer and closer to the large truck in front of it. I kept applying the brake and then pumping the brake. The brakes kept failing and had no pressure or tension in them to stop the car. The brake pedal was flat on the floor. But, thanks to a sufficient distance between my car and the truck in front of it, it rolled to a stop just short of crashing into the back of said truck by an inch or two. Sometime in October of 2024 , I spoke with a Service Rep at Marietta Toyota about a whizzing sound that appeared to be coming from under the hood on the driver’s side. This sound would occur while I was driving and even when I turned the car off. It would continue making this whizzing sound sometimes for as long as 45 minutes after the ignition was turned off. I took the car back to Marietta Toyota and the service rep said the problem was related to the weather. On December 24, 2024, at around 11:00am EST, I parked my car in the parking lot in front of a print shop. The weather was clear, and the pavement was dry as I pulled my car into a clean, unfettered spot. Upon returning to my car, I could see a fresh puddle under the front passenger side. I ran my finger across the liquid that presented itself as a clean, thin oil that was as smooth as silk. It was odorless and sat in a pristine area looking freshly run out from the underside of my car. On February 27, 2025, when driving in the middle lane on Highway I-20 West, the ABS warning lights came on my dashboard screen along with the image of a skidding car. I was frozen with fear and did not know what would happen next. I would have to cross over multiple lanes to exit off Highway 1-20. I put on hazard lights and drove at 25-35 mph. Took car in for diagnostic and repair.

The brake booster assembly (part number 47070-47060) on my 2013 Toyota Prius has failed. This component is critical to the proper functioning of the braking system. It is currently still installed in the vehicle and available for inspection upon request. As a result of the failure, the ABS warning light, traction control light, and brake warning light are all illuminated on the dashboard. The braking performance has noticeably declined — the pedal feels inconsistent and at times unresponsive. This has created a significant safety risk while driving, especially during sudden stops or in wet conditions, as it compromises the vehicle's ability to brake efficiently and predictably. The issue has been confirmed by a Toyota dealer (or independent mechanic if that’s the case — feel free to change this line accordingly). The dealer diagnosed the issue as a failure of the brake booster assembly, which aligns with known failures reported by many other 3rd-generation Prius owners. The vehicle has not been involved in an accident, and has not been inspected by the police or insurance representatives. Toyota previously issued a Customer Support Program (CSP ZJB or ZG1) covering this part, but it has since expired. I only recently began experiencing symptoms and was unaware of the CSP until after contacting Toyota. Prior to the warning lights, I experienced intermittent symptoms such as a soft or delayed brake pedal, and an unusual sound from the brake system when the vehicle was turned off. The warning lights first appeared around [insert approximate mileage or date here], and have remained illuminated since then. Given the safety-critical nature of this component and the known defect history, I am requesting assistance from Toyota in the form of goodwill coverage or reimbursement, and would like this issue escalated for further review.

Inverter and brake booster

While driving on the highway, ABS, "Brake"/E-Brake, Traction Control Lights lit up all at the same time out of the blue. No prior engine lights/codes before this incident. During that trip, brakes felt more difficult to press, loss all brake regeneration for the hybrid battery but was still about to brake for that entire 100 miles trip. As of now, the car is still able to brake but it looks like it's just primarily using the mechanical brakes all the time now. It still has that different brake feel compared to when before all those engine lights went on. Regenerative braking is no longer working. Brought the car to the shop at was given the error codes C1391 and C2315.

I was driving and suddenly the car started beeping and the brake, e-brake, abs, and traction control lights came on. As soon as I found an opportunity I tried to brake but the car would not stop and the brake pedal became really hard. I had swerve to avoid hitting cars in front of me. It was the scariest moment of my life. I shifted the car from D to B to use the engine braking. I finally was able to slow down enough to turn right on a side Street and pushed on the brake pedal with all my strength and it finally came to a stop. I was lucky I didn't have a collision or strike a pedestrian, that I also drive defensively and leave enough space in front of me, and that I was on a surface street and not on a freeway which I frequently use because if I was I would have surely crashed. This is NOT right. Brakes should NOT suddenly fail! Under any circumstances. It was confirmed by a mechanic that it's the BRAKE BOOSTER AND BRAKE BOOSTER PUMP ASSEMBLIES had failed and had the following codes C1252, C1253, and C1256 were found. The same issue and codes reported in tsb pol18-03.

The contact owns a 2013 Toyota Prius. The contact stated while driving approximately 5 to 10 MPH, the vehicle stalled. The contact was able to restart the vehicle, but the failure persisted. There were no warning lights illuminated. The vehicle was taken to an independent mechanic, who replaced the battery on two occasions, but the failure reoccurred. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 173,699.

Mileage: 173,699

Took vehicle for state inspection on 2/13/2024, failed inspection because of brake warning lights. Slip indicator, Electronically controlled brake warning light, Brake warning light, Anti-lock brake system, and Low tire pressure lights are all on. I have looked into it, and it seems the brake actuator/booster used to be under warranty, however since this is a 2013 in 2024 with almost 210k miles on it, it no longer qualifies for the original recall.

The contact owns a 2013 Toyota Prius. The contact stated that after several days of torrential rainfall, the contact noticed there was water in the tire and 12-volt battery compartment. After having a routine oil change at an independent mechanic, while the contact was driving, the vehicle lost power steering functionality. The power steering warning light illuminated after the failure. The driver was able to restart the vehicle and pull over to the side of the road. The contact called Roadside Assistance and was informed that there was a code for the hybrid battery system that needed to be checked. The contact noticed that water might have entered through the rear passenger’s side brake light. The contact removed the water with a sump pump. The vehicle was towed to an independent mechanic who was unable to assist. The vehicle was towed to the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 119,000.

ABS Brake Warning Light On-stays on-this just happened within last 2 weeks. Not sure on safety measures but unsure if I keep driving it the brakes will just give out. The problem has been confirmed and seen by Tire Max but no diagnostic tests were ran. The just saw the light was on. No one has inspected the vehicle component by the manufacturer, police, or insurance company. No warning lamps prior to the problem but the ABC Warning light stays on while cranked and it first appeared about 2 weeks ago. I do want to add that a similiar recall or warranty had been put out by Toyota on Sept 4th 2020-(T-SB-0089-20) for 2012-2014 Prius V & C stating: "Some 2012-2014 model year Prius V hybrid vehicles may exhibit a condition where the brake, ABS, and/or TRAC warning lights are on and/or a Check VSC message displays. Diagnostic Trouble Codes (DTCS) C1391, C1252, C1256, C1253 may be stored. This condition may be caused by a small internal brake fluid leak inside the brake booster assembly with master cylinder. The warranty was for Prius V or C but my Prius(no V or C) has been affected with the same issue but Toyota will not honor this warranty or recall due to the problem not showing as specific to my vin#. So I am reporting this problem so it can be submitted that there is a similar problem with my Prius as well as the Prius V or C so others could submit their problem as well. I cannot afford to fix this myself. I need Toyota to back up their cars.

Brake system failure. Traction control light, brake light, abs light, and brake system warning light all lit up on dash. The regenerative braking is no longer working or charging battery. Obvious loss of stopping power. Does not feel safe to drive at all. Toyota wants $3,000-$4,000 for the repair. Toyota should be held liable for these failures causing crashes and potential fatalities. This should already be a recall.

Check hybrid system. Stop the vehicle in a safe place. About 90,000 miles 2013 Prius bought brand new and regular all dealer maintenance completed. Lost power on the road and very slow pickup. Not drivable and very unsafe car. Thanks.

Driving down the road and the brake light, ABS light, VSC light and a ! with a circle around turned on in the dash. My breaks almost stopped working I almost hit the car in front of me. I've been try to figure out what's wrong and keep hearing this is a brake booster/ actuator problem. I have parked the car due to the brakes barley working.

The contact owns a 2013 Toyota Prius. The contact stated that the hazard lights would activate inadvertently and were not able to be turned off as designed. The vehicle was taken to a local dealer but was not yet diagnosed or repaired. The manufacturer was informed of the failure but offered no assistance. The failure mileage was approximately 124,000

We have been experiencing on multiple occasions car while driving will slow down, hybrid safety warning light on dashboard will turn on and tell us we have to go to a safe area and turn off car. The car will automatically shut down like a golf cart feeling. We have had near incidents were we have almost crashed. The car now will not go past 35 miles. We brought the car to a Toyota Dealership because we noticed their was a software update recall. When we left the car repeated the warning again about 5 minutes leaving the dealership. The dealership has not helped us and refuses to fix car. We mentioned to them that there have been many complaints regarding the same issue.

The car has been stopping on me anytime I go 35 mph or more. The check hybrid system warning light appears then the far shuts down.I have been having this problem for over a year now after Toyota techs have performed all other software updates.I have replaced hybrid battery 12 v battery both water pumps sensors along with a low mile engine.my year car is on all recall list except the inverter replacement which is the problem.I have spent several thousand dollars on a no end issue .

I was loving my Prius until yesterday June 9, 2021 when I took it to Toyota of Riverhead, NY to have my Hazard lights checked because they would not shut off. I was told that the technician found ABS actuator shorting out causing the hazards to not go off. The replacement would be $2664. I had the fuse removed because it was causing my battery to die with the hazard lights being on. I was also advised by Tonianne Rempel (service advisor) that Toyota was familiar with this problem with 2013 Prius. I have a problem with Toyota knowing that there is a problem with the hazards for this is potentially dangerous for it makes your battery die and leaving the owner stranded. This should have been a recall. I had removed the fuse so now I have no hazards or directionals leaving me to use hand signals. Which is extremely dangerous for other drivers do not look for driver using hand signals. This embarrassing for Toyota drivers seeing that somebody driving a Toyota is using hand signals because the directionals don’t function. Toyota should have done a recall knowing that this hazardous situation exists. I am asking Toyota to pay for this repair. I do not have $2664 to repair this hazardous situation that should have been addressed by Toyota and leaving me in a very dangerous situation without hazards or directionals.

MY TOYOTA PRIUS WAS INVOLVED IN A HIT RUN ACCIDENT. YARK COLLISION COMPLETED WORK ON VEHICLE. WHEN PICKING UP CAR FROM YARK MY CAR WOULD NOT START SPOKE WITH ONE OF THE MECHANIC HE SAID MY BATTERY DIED AND I EXPLAINED TO THEM I HAD NO ISSUES ,PRIOR TO BRINGING MY CAR TO YARK I HAD JUST HAD DIAGNOSTIC TEST DONE AT TOYOTA. VEHICLE SAT AT MY RESIDENCE OVER NIGHT AND VEHICLE HAD DIED AGAIN. I CONTACTED YARK TOLD THEM I WAS BRINGING BATTERY IN FOR THEM TO CHARGE BECAUSE I WAS NOT SURE AS TO WHAT WAS GOING ON SINCE WE HAD ALREADY REPLACED BATTERY. VEHICLE ALSO HAD MY SKID PLATE IN TRUNK PRIOR TO DROP OFF AND NOW I AM HAVING ELECTRICAL ISSUES MY HORN NOW DOES NOT WORK AND I HAVE CHILDREN .I DID NOT RECEIVE MY CAR UNTIL 1 MONTH AND HALF DUE TO INSURANCE NOT GETTING BACK TO US . VEHICLE HAS BEEN NON DRIVABLE SINCE PICK UP.

THE CAR GAVE A TRIANGLE OF DEATH AND LOOKED IT UP IF ANY RECALLS HAD BEEN MADE THAT COULD POSSIBLE CAUSE THIS ISSUE AND THERE WAS 1 THAT CALLED FOR AN UPDATE TO THE SYSTEM WHICH I HAD DONE AND THEY HAD TOLD ME IF IT DIDN'T TAKE THEY WOULD HAVE TO DO THE INVERTOR WHICH WAS APART OF THE RECALL. A WEEK AFTER THE SYSTEM UPDATE THE SAME ISSUE AROSE AND THEY REFUSED TO REPLACE THE INVERTOR WHICH DRAINED THE HYBRID BATTERY AND RUINED IT ALSO . THIS EFFECTS THE DRIVING ABILITY AND CAUSES THE CAR TO SHUT DOWN THE LIGHTS TO NOT WORK . IT CAN STALE AT ANY GIVEN TIME AND WILL NOT HAVE POWER TO CONTINUE

I AM HAVING PROBLEMS WITH RODENTS GETTING INTO MY CAR. I FEAR THAT THEY ARE CHEWING ON ELECTRICAL WIRING AND THERE IS POSSIBLE DISTRACTION TO THE DRIVER. WHEN I WAS DRIVING (CAR WAS MOVING) A MOUSE CRAWLED UP ON MY SHOULDER. THESE PROBLEMS APPEAR TO BE A PROBLEM WITH THIS MODEL TOYOTA AND COULD CAUSE A DISTRACTION TO THE DRIVER AND A DRIVING ISSUE WITH WIRING.

WHILE DRIVING OUR 2013 PRIUS ON A 5 FIVE-LANE HIGHWAY 2-10-20, OUR PRIUS GOES INTO LIMP HOME MODE ALL THE SUDDEN AND SLOWS THE CAR DOWN SIGNIFICANTLY WHILE DRIVING AT HIGHWAY SPEED. THIS OCCURRED AT THE SAME TIME AS I WAS PASSING A CAR TO EXIT THE HIGHWAY, ALSO WITH ANOTHER CAR CLOSE AT THE REAR CLEARLY INTENDING TO GET AHEAD OF ME AFTER I HAD PASSED THE OTHER CAR. I UNEXPECTEDLY REALIZED THAT I HAD NO ACCELERATION AND THAT THE ALL THE DASH LIGHTS HAD COME ON. I WAS VERY FORTUNATELY TO BE ABLE TO MANEUVER ACROSS THE DRIVING LANES TO THE HIGHWAY EXIT WITHOUT BEING HIT AS MY SPEED GO DOWN. THE SITUATION WAS EXTREMELY HAZARDOUS. TOOK THE CAR TO THE TOYOTA DEALERSHIP THE NEXT DAY ON 2-11-20 AND THE TECH DISCOVERED THE CAR WENT INTO THE LIMP HOME MODE BECAUSE OF A CATASTROPHE INVERTER FAILURE. WE DID RECEIVE THE UPDATED SOFTWARE FROM THE RECALL IN 2014, YET THE INVERTER STILL FAILED. THE INVERTER WAS REPAIRED BY THE TOYOTA DEALERSHIP 100% UNDER WARRANTY.

I WAS DRIVING DOWN A CITY ROAD AT 25-30 MPH AT DUSK (5:15PM), AND WITH MY HEADLIGHTS ON. THE FIRST INDICATION OF A PROBLEM WAS THE SMELL OF BURNING RUBBER WHEN I TURNED ON THE HEATER. ASSUMING THE PROBLEM WAS WITH ANOTHER VEHICLE AHEAD OF ME, I TURNED OFF THE HEATER AND KEPT DRIVING. A MILE LATER, AS I WAS NEARING MY DESTINATION, I NOTICED SEVERAL WARNING LIGHTS TURN ON (SKID LIGHT AND EXCLAMATION MARK LIGHT) AND THE STEERING BECAME LESS RESPONSIVE. I THEN SAW SMOKE EMITTING FROM UNDER MY HOOD. A FEW SECONDS LATER, THE FRONT PASSENGER-SIDE CORNER OF THE CAR BURST INTO FLAMES. I MANAGED TO PULL OVER, WOKE UP MY TWO YOUNG CHILDREN FROM THEIR CAR SEATS, AND GOT EVERYONE OUT. WITHIN A MINUTE, THE ENTIRE HOOD WAS ABLAZE. GIVEN WHERE THE FIRE STARTED, I SUSPECT THE HEADLIGHT. I REPLACED IT THE DAY BEFORE. THE LIGHT SEEMED TO WORK FINE FOR 1 DAY, BUT IT IS SUSPICIOUS THAT IS ALSO THE AREA WHERE THE FIRE STARTED.

ENGINE WARNING LIGHT AT START UP CAME ON WITH NO DEGRADATION OF OPERATION. CAR WAS TAKEN TO ORIGINATING MANUFACTURE DEALER FOR DIAGNOSIS. WHEN CAR WAS PURCHASED AS CERTIFIED PRE-OWNED THE SALES REP UPSOLD EXTENDED 3RD PARTY WARRANTY COVERAGE THAT THEY SAID 'WOULD COVER EVERYTHING INCLUDING DIAGNOSIS LABOR FEES.' WHEN VEHICLE WAS DIAGNOSED FROM DEALER SERVICE DEPT THEY SAID IT WAS FAULTY O2 SENSOR, CAUSED 'BY RODENT DAMAGE TO CABLE'. NO VALIDATION OR EVIDENCE OF THIS WAS PROVIDED; CABLE/PARTS NOT PRESENTED FOR INSPECTION TO CUSTOMER. CUSTOMER WAS TOLD LACK OF SENSOR WOULD RESULT IN REDUCED GAS MILAGE. CUSTOMER ASKED ABOUT SAFETY OF VEHICLE AND WAS TOLD VEHICLE WAS SAFE TO DRIVE WITHOUT PART REPAIR. CUSTOMER ASKED IF REPAIR WAS COVERED UNDER WARRANTY AND WAS TOLD THAT IT WAS NOT. CUSTOMER DECLINED REPAIR AT THAT TIME; CUSTOMER WAS FORCED TO PAY ~$150 LABOR CHARGE FOR INSPECTION. CUSTOMER RETURNED AT A LATE TIME TO COMPLETE REPAIR. AGAIN NO EVIDENCE OF PART FAILURE WAS PRESENTED AND REPAIR COST ~$400 WAS FORCED TO BE PAID. CUSTOMER THEN FOUND EXTENDED WARRANTY COVERAGE DOCUMENTS AND CALLED THEM TO ASK WHY REPAIR WAS NOT COVERED AS PROGRAM DOCUMENTATION AND CONTRACT SEEMED TO INCLUDE COVERAGE OF THIS ISSUE; PROVIDER NOTED THAT DEALER DID NOT CALL TO AUTHORIZE REPAIR AT NO COST TO CUSTOMER AND CUSTOMER SHOULD SUBMIT PAPERWORK TO PROVIDER FOR REVIEW. CUSTOMER FURTHER RESEARCHED ON INTERNET THE ISSUE AND FOUND MULTIPLE REPORTS OF FAULTY WIRING AND IS CONCERNED FOR SAFETY OF OPERATION DUE TO MANUFACTURE MATERIAL FLAWS THAT ALLOW ANIMAL DAMAGE TO CRITICAL WIRING OF CAR.

ON JAN 2, 2017, I ATTEMPTED TO START MY 2013 TOYOTA PRIUS. THE VEHICLE DASH HAD THE FOLLOWING WARNING LIGHTS ILLUMINATED, CHECK HYBRID, ELECTRONIC POWER STEERING WARNING, BRAKE WARNING LIGHT AND THE MASTER WARNING LIGHT. THE VEHICLE WOULD NOT SHIFT INTO DRIVE OR REVERSE AND WOULD ONLY DEFAULT TO THE NEUTRAL POSITION. UPON OPENING THE HOOD OF THE ENGINE COMPARTMENT I NOTICED THE WIRING TO THE HYBRID INVERTER HAD BEEN EXTENSIVELY DAMAGED (CHEWED, GNAWED) TO THE EXTENT THAT THE PHYSICAL WIRES WERE TOUCHING EACH OTHER AND POSSIBLY SHORTING OR GROUNDING TO EACH OTHER. MY VEHICLE WAS TOWED TO STEVENSON TOYOTA WEST LOCATED AT 780 INDIANA ST, LAKEWOOD, CO. ON JAN 3, 2017. ON JAN 4, 2017 I WAS CONTACTED BY SERVICE ADVISOR MIKE HASHMAN WHO TOLD ME THE DAMAGE WAS CAUSED BY A RODENT(S) CHEWING ON THE WIRING. THE DAMAGE WAS AS FOLLOWS: HV INVERTOR WIRES (2) WERE DAMAGED, A/C COMPRESSOR HV WIRE WAS DAMAGED, INVERTOR COOLANT TANK WERE ALL REPLACED BECAUSE OR EXTENSIVE DAMAGE. ALONG WITH INVERTOR COOLANT AND LABOR THE TOTAL COST OF THE REPAIR WAS $1,279.63. WE HAVE A $1,000.00 DEDUCTIBLE POLICY SO OUR TOTAL COST WAS THE DEDUCTIBLE. I HAVE SINCE DISCOVERED THAT TOYOTA HAS BEEN, SINCE APPROXIMATELY 2009 THROUGH 2016 AND POSSIBLY 2017, BEEN USING SOY BASED WIRING COVERING AND CABLE WRAP WHICH IS VERY ATTRACTIVE TO RODENTS. IN OUR CASE THE RODENT WOULD BE BROWN SQUIRRELS. I HAVE ALSO FOUND A CLASS ACTION LAWSUIT FILED ON JAN. 6, 2017, IN THE US DISTRICT COURT FOR THE WESTERN DISTRICT OF WASHINGTON, ALLEGING TOYOTA HAS KNOWN OF THE PROBLEM BUT HAS REFUSED STEADFASTLY REFUSED TO ACCEPT RESPONSIBILITY. MY CONCERN IS HAD THE CATASTROPHIC FAILURE OF THE ELECTRONICS OCCURRED WHILE I WAS DRIVING THE CONSEQUENCES COULD HAVE BEEN FATAL TO MYSELF, PASSENGERS AND OTHERS OCCUPYING VEHICLES NEXT TO OR NEAR ME BECAUSE OF THE POWER STEERING AND BRAKE ERRORS. THE VEHICLE WAS PARKED IN OUR DRIVEWAY.

FIRST, UNDERSTAND THERE WAS NO ACCIDENT, NO ONE GOT HURT, AND IT DIDN'T COST ME A DIME. THE DEALER AND WARRANTY PICKED UP THE FULL TAB. ALL IT COST ME WAS A LITTLE AGGRAVATION. HOWEVER, I FEEL IT SHOULD NOT HAVE HAPPENED. IT STARTED WHEN I HAD A FLAT TIRE. I REMOVED THE FLAT AND PUT ON THE SPARE, NO PROBLEM. THE TIRE HAD A SIDEWALL PUNCTURE SO FIRST THING MONDAY I TOOK IT TO GK TIRE & AUTO FOR REPLACEMENT. THEY MOUNTED A NEW TIRE AND PUT THE SPARE BACK IN THE TRUNK. THAT IS WHERE THINGS WENT WRONG. MY PRIUS WOULD NOT START. I CALLED THE DEALER. THE DEALER SENT A TOW TRUCK AND HAULED THE PRIUS OFF. THE NEXT DAY THEY CALLED TO SAY IT WAS FIXED. THE SERVICE TICKET SAID "PULLED CODE P0A0D...CLEARED CODES, AND CHECKED SERVICE PLUG. FOUND PARTIALLY PULLED OUT." ... "INSTALLED SERVICE PLUG ALL THE WAY AND TEST DROVE VEHICLE. GOOD, DONE". BECAUSE GK TIRE HAD NO REASON TO BE ANYWHERE BUT IN THE TRUNK I ASSUME THAT IS WHERE THE 'SERVICE PLUG' IS AND THEY KNOCKED IT OUT OF PLACE WHEN THEY RE STOWED THE SPARE. MY PROBLEM IS THAT IF THE TIRE PEOPLE COULD DO THAT, THEN I MIGHT HAVE DONE THAT. AND, IF I HAD DONE THAT IT COULD HAVE BEEN IN THE MIDDLE OF NO WHERE, OR EVEN WORSE, THE CROSS BRONX EXPRESSWAY. I WOULD NOT EXPECT THAT I WOULD HAVE TO TREAT THE TIRE COMPARTMENT OF A TRUNK LIKE A FINE SWISS WATCH. IF THAT WAS THE PROBLEM, I CONSIDER IT A DESIGN DEFICIENCY. WHEN GK TIRE PUT IT ON THE LIFT? STILL A DESIGN DEFICIENCY. IT SHOULD NOT HAVE HAPPENED. *TR

TL* THE CONTACT OWNS 2013 TOYOTA PRIUS 5. THE CONTACT STATED THAT WHENEVER SHE WAS DRIVING IN REVERSE, THE VEHICLE WOULD JERK VIOLENTLY. IN ADDITION, THE INTERIOR DOME LIGHT WOULD ILLUMINATE SPORADICALLY. THE CONTACT STATED THAT ALL OF THE LIGHTS ON THE INSTRUMENT PANEL AND RADIO CONSOLE FAILED TO ILLUMINATE AFTER STARTING THE VEHICLE. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 3,000. THE CURRENT MILEAGE WAS 10,900.

EVERY TIME I RECEIVED CALL ON MY CELL BLUETOOTH SEEMS LIKE VOICE BREAKING UP. IT IS NOT THE PHONE PROBLEM. I HAVE CHECKED THE SAME PHONE IN MY OTHER CARS AND WORKS FINE. THIS BLUETOOTH NEEDS SOFTWARE UPGRADE. *TR

WHILE DRIVING THE CAR--ON NUMEROUS OCCASIONS--THE DASH LIGHTS ALL ILLUMINATE AT ONCE, FOLLOWED BY UNRESPONSIVE CONTROLS FOR A FEW SECONDS. THEN THE DASH LIGHTS GO OUT (RETURN TO NORMAL) AND NORMAL CONTROLS AND ACCELERATION RETURN. *TR

WHILE SLOWING DOWN FOR A RED LIGHT THE CAR'S ELECTRONICS MADE A BEEPING NOISE, ALL THE DASH LIGHTS CAME ON, THE GAS GAUGE DISPLAYED A RAPIDLY DROPPING QUANTITY, THEN WENT BACK UP TO HALF FULL. A RED TRIANGLE WAS DISPLAYED ON THE DASH DURING THIS TIME. DURING THIS TIME, THE CAR WAS COMPLETELY DISABLED AND UNABLE TO MOVE AND WAS SITTING IN THE INTERSECTION. I TRIED MULTIPLE TIMES TO RESTART THE CAR, THE DASH LIGHTS WOULD COME ON, BUT THE CAR WASN'T ACTUALLY RUNNING OR RESPONDING TO PEDAL INPUTS. AFTER 7 MINUTES THE CAR FINALLY STARTED BACK UP AND I WAS ABLE TO DRIVE TO THE DEALERSHIP. I LEFT THE CAR'S ENGINE RUNNING (EV MODE WHILE PARKED) AND THEY HOOKED IT UP TO THE COMPUTER. THEY SAID EVERYTHING WAS FINE AND THEY COULDN'T FIND ANYTHING WRONG WITH IT. THIS HAS HAPPENED BEFORE, AND IT HAPPENED AGAIN, TWO DAYS AFTER THE DEALERSHIP GAVE ME MY CAR BACK (THEY KEPT IT THAT WEEKEND). *TR

WHILE DRIVING ON THE FREEWAY THE CAR'S DASH LIT UP AND THE CAR'S ENGINE DIED AND THEN RESTARTED. THE FUEL QUANTITY DISPLAYED, DECREASED BY THREE BARS BEFORE RETURNING TO IT'S NORMAL--ACCURATE--LEVEL. THE CAR THEN DROVE NORMALLY AND ALLOWED ME TO GET IT INTO THE DRIVEWAY. *TR

WHEN PUTTING THE VEHICLE IN REVERSE A LOUD BEEPING IS HEARD INSIDE THE CABIN. WE AREN'T SURE OF ITS PURPOSE AS THE BEEPING CANNOT BE HEARD OUTSIDE OF THE CAR IF THE WINDOWS ARE UP OR IF THE WINDOWS ARE DOWN AND THE RADIO IS ON. THE BEEP CAN ONLY BE FAINTLY HEARD OUTSIDE OF THE VEHICLE IF THE WINDOWS ARE DOWN AND THERE IS NO OTHER NOISE. BECAUSE THE BEEPING IS SO LOUD IN THE VEHICLE, THE DRIVER CANNOT HEAR SHOUTS, SCREAMS OR OTHER DISTRESS SIGNALS TO ALERT THEM OF A HAZARD WHEN BACKING UP. THE BEEPING IS LOUD AND CONSTANT AND IS NOT AFFECTED BY THE NEARNESS OF AN OBJECT, AS WITH OTHER VEHICLE BEEPING BACKUP SYSTEMS. THE LOUD BEEPING CREATES A HAZARD BY DISTRACTING THE DRIVER AND NOT ALERTING PEOPLE OUTSIDE OF THE VEHICLE. *TR

TOYOTA PRIUS EMITS A LOUD AND DISTRACTING BEEPING TONE INSIDE THE CABIN WHEN PLACED IN REVERSE. THE TONE IS SO LOUD THAT A DRIVER MAY NOT HEAR SHOUTS, A HORN, OR OTHER EXTERIOR NOISE INDICATING A HAZARD WHILE REVERSING. TOYOTA DEALERSHIPS CHARGE HUNDREDS OF DOLLARS TO TURN OFF THE INTERIOR BEEPING, DESPITE THE EVIDENT SAFETY HAZARD IS POSES. *TR
