Service brakes
8 reports4 crashes1 fire
“Vehicle is not available for inspection upon request due to the vehicle being in an accident. As a result from the accident, the vehicle was a complete loss and beyond the point of repair. Without pulling the vehicle computer for operation list before accident occurred, it is specifically unknown what component or system failed and or malfunctioned. looking at pictures taken the night of and days after it seems like it was a steering/suspension, or possible wheel malfunction that was unable to keep the car under and in control to be brought to a full stop before the point of impact and accident occurred.”
Electrical system
4 reports1 crash
“ON SEVERAL OCCASIONS THE HOUSING AROUND THE AIR CONDITIONER FILLS WITH WATER FROM CONDENSATION, THE DRAINAGE TUBE IS NARROW AND CLOGS, WHICH CAUSES THE WATER TO DRIP OUT OF THE HOUSING AND INTO THE PASSENGER SIDE INTERIOR WHERE IT SWAMPS THE CARPETING FROM FRONT TO BACK. I KNOW AC NORMALLY DOES NOT QUALIFY AS A SAFETY CONCERN BUT TO MY UNDERSTANDING THERE IS ELECTRIC WIRING THAT RUNS UNDER THE CARPET THAT IS CERTAINLY NOT DESIGNED TO BE UNDER AN INCH OF WATER AND THEN THERE IS THE POTENTIAL FOR HARMFUL MOLD TO DEVELOP FROM THE WET CARPET. THE DEALER WILL CHARGE TO CLEAR THE CLOG BUT THEY HAVE SINCE TOLD ME THERE IS A PERMANENT FIX (AN AC CASING WITH BETTER DRAINAGE) WHICH COSTS MORE THAN $2000 TO INSTALL. A SIMPLE SEARCH ON THE INTERNET SHOWS TOYOTA HAS BEEN IGNORING THIS DESIGN FLAW AND THIS PROBLEM SINCE THE MODEL REDESIGN IN 2011. THEY HAD PLENTY OF TIME TO ADDRESS THIS ISSUE WHICH CAN EFFECT THE HEALTH AND SAFETY OF THE OCCUPANTS. I KNOW A NARROW TUBE DRAIN LINE SEEMS LIKE A MINOR THING BUT THIS DOES NOT SEEM TO HAPPEN IN MOST CARS. WHILE IT HAS BEEN A CONCERN FOR SCION TC OWNERS SINCE 2011. I DRIVE A 2014. THERE WAS PLENTY OF TIME FOR TOYOTA TO OFFER A…”
Air bags
3 reports1 crash
“MI VEHICLE IS IN MOTION THE BRAKES HAVE A SOUND AND THE AIR BAG IS TURN ON”
Suspension
2 reports1 crash1 fire
“AIR BAG TURNS OFF RANDOMLY WITHOUT WARNING, LIGHT COMES ON WHILE DRIVING. ALSO VEHICLE IS DUE TO HAVE TRD BRAKES REPLACED.”
Steering
2 reports1 crash
“I WAS DRIVING ON HIGHWAY 522 GOING 60MPH AT 11:30PM. THE HIGHWAY WAS SMOOTH AND HAD NO BUMPS THEN RANDOMLY THE WHEEL ON THE REAR PASSENGER SIDE BROKE OFF THE CAR AND WENT FLYING. POLICE OFFICERS AND STATE TROOPERS LOOKED FOR THE WHEEL AND THEY COULDN'T FIND IT. LUCKILY I REMEMBERED IN DRIVERS ED THAT WHEN A TIRE BLOWS OUT (EVEN THOUGH THIS SITUATION IS A LITTLE DIFFERENT) YOU FIRMLY HOLD ONTO THE STEERING WHEEL AND HOLD IT STRAIGHT. THE CAR THEN STRAIGHTENED OUT AND STOPPED ONCE I RAN INTO THE RAILING.”
Wheels
2 reports2 crashes
“WAS COMMUTING BACK TO WORK FROM LUNCH BREAK WHEN OUT OF NOWHERE I LOST CONTROL OF STEERING AND BRAKING OF MY VEHICLE CRASHING INTO A STONE WALL BEFORE I COULD PULL MY EMERGENCY BREAK AFTER THE VEHICLE COULD NOT SLOW DOWN ON A CITY STREET IN MOTION”
