Hybrid Propulsion System › Inverter13V396000
Filed Sep 4, 2013133,081 vehiclesToyota Motor Engineering & Manufacturing
Defect. Toyota is recalling certain model year 2006-2010 Highlander hybrid vehicles manufactured February 16, 2005, through July 29, 2010; and model year 2006-2008 Lexus RX400h vehicles manufactured February 23, 2005, through December 2, 2008. The Intelligent Power Module (IPM) inside the inverter module may contain transistors that have higher operating temperatures than the solder can support and the transistors may be heat damaged by the solder. If this occurs, various warning lamps, including the malfunction indicator lamp, slip indicator light, brake system warning light, and master warning light, will be illuminated on the instrument panel.
Risk. The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. It is possible that the hybrid system will shut down while the vehicle is being driven, causing the vehicle to stall unexpectedly, increasing the risk of a crash.
Remedy. Toyota will notify owners, and dealers will replace the IPM free of charge. Owners may contact Toyota at 1-800-331-4331. Vehicles that had their IPM replaced under recall 11V-342 are not affected by this campaign.

When the ABS actuator pump fails, it stops regulating and maintaining hydraulic pressure in the brake lines which can lead to brake failure. No recall was ever issued despite the fact that a failure of the braking system.

STARTED NOTICING "BURPING" NOISE WHEN I PRESSED ON BRAKES FROM ENGINE BAY, THEN LATER I NOTICED CONTINUOUS CLICKING SOUND COMING FROM FRONT PASSENGER ENGINE BAY AFTER I WOULD TURN OFF ENGINE COMPLETELY. AS LATER TIME WENT BY THE CLICKING SOUND WOULD GET LONGER AND CONSISTENT. I ALSO EXPERIENCED THAT THE VEHICLE WOULD "LUNGE" FORWARD WHEN I WOULD START THE ENGINE AND INITIALLY SHIFT THE VEHICLE INTO DRIVE POSITION AND HAVE TO PUMP THE BRAKE PEDAL TO COMPLETELY STOP. THATS WHEN UPON FURTHER RESEARCH ONLINE I FOUND A "WARRANTY ENHANCEMENT" FROM TOYOTA REGARDING BRAKE ACTUATOR BEING REPLACED. BUT TOYOTA PUT A 10-YEAR EXPIRATION ON THE WARRANTY SO MY VEHICLE DIDN'T QUALIFY BY 6 MONTHS! TOYOTA NEVER MADE AWARE OR REACHED OUT TO THEIR REGISTERED CLIENTS OF THIS DANGEROUS RECALL THAT IS $3,000.00 TO REPLACE. I WAS INFORMED THAT WHEN THE BRAKE ACTUATOR COMPLETELY GOES BAD THAT STOPPING THE CAR WILL BE ALMOST IMPOSSIBLE TO STOP FOR THE AVERAGE DRIVER AS THE BRAKE ACTUATOR APPLIES NEEDED BRAKE FLUID PRESSURE TO ALL FOUR BRAKE CALIPERS TO SLOW THE VEHICLE DOWN.

WHILE DRIVING ON A CITY STREET, I LOST POWER STEERING COMPLETELY. P/S AND BRAKE DASH LIGHTS CAME ON ALONG WITH "SERVICE HYBRID SYSTEM" AND "SERVICE AWD SYSTEM". AFTER A FEW MORE MILES THE VEHICLE LOST COMPLETE PROPULSION POWER AND I WAS FORCED TO PULL OUT OF TRAFFIC. I TURNED OFF THE VEHICLE AND IT STARTED FINE WITH NO POWER STEERING. I MADE THE NEXT MILE TO THE DEALERSHIP. THEY REPLACED THE ECU THAT HAD SHORTED OUT DUE TO A BAD STEERING RACK. I AM NOT SURE WHY THE ELECTRONIC STEERING MECHANISM WOULD CAUSE COMPLETE LOSS OF POWER FROM THE ENGINE/HYBRID SYSTEM?

I HAVE NOTICED THIS ISSUE A COUPLE OF TIMES OVER THE 7 YEARS I HAVE HAD THE CAR (SINCE IT WAS NEW), MOST RECENTLY YESTERDAY: WHEN I AM TRAVELING AT MEDIUM SPEEDS, SAY 30-45 MPH, AND I HIT A BUMP IT FEELS LIKE I GET A LITTLE "PUSH IN THE BUTT". SORT OF LIKE A FORWARD SKID. SO THEN I APPLY THE BRAKES A BIT. DON'T KNOW HOW ELSE TO DESCRIBE THIS. MY HUSBAND SAYS THAT HE CAN'T FEEL IT WHEN HE IS A PASSENGER.

ONE OF THE 2 HYBRID MODULES FAILED. I BELIEVE THIS IS THE SAME ONE RECALLED IN 2013. THE VEHICLE STOPPED AND ENGINE WOULD NOT TURN OVER. ALL DASHBOARD WARNING LIGHTS CAME ON ALONG WITH CHECK HYBRID ENGINE AND CHECK VCS ( I THINK WERE THE INITIALS, FOR VEHICLE CONTROL SYSTEM). HAD THE CAR BEEN TRAVELLING AT HIGHWAY SPEEDS I BELIEVE A FATAL CRASH WOULD HAVE OCCURRED. AS IT WAS, LUCKILY, WE WERE IN STOP AND GO TRAFFIC. HAD CAR TOWED OFF HIGHWAY BUT TOW TRUCK DRIVER TOLD ME HE DROVE IT UP ON THE FLATBED. I HAD TRIED STARTING IT SEVERAL TIMES WITHOUT ANY SUCCESS. ONCE OFF ROAD, I CALLED THE DEALERSHIP, WHO IS OPEN SATURDAYS UNTIL 3 PM AND IT WAS APPROXIMATELY 2:30 PM. I WAS TOLD THAT IF ALL THE LIGHTS WENT OFF AND THE CAR STARTED THAT I COULD DRIVE IT HOME. THAT IS WHAT HAPPENED. I MADE AN APPOINTMENT FOR THAT MONDAY WHILE ON THE PHONE WITH THE DEALER SO THAT THE PROBLEM COULD BE CHECKED OUT. IT TURNS OUT THAT THIS MODULE, WHEN HEATED UP TO HIGH TEMPERATURE, CAN FAIL BY THE SOLDERING CONTACTS OPENING AND THE POWER THEREBY FAILING. THIS IS THE PROBLEM THAT THE 2013 RECALL WAS SUPPOSED TO CORRECT. HOW DO I KNOW THAT THIS NEW MODULE WILL NOT FAIL AGAIN WITHOUT WARNING? LEXUS ABSORBED THE LABOR ON THE MODULE REPLACEMENT BUT CLAIMED THE PART (WHICH WAS THE RECALL PART INSTALLED TO CURE THE RECALL PROBLEM IN 2013) WAS NO LONGER UNDER WARRANTY AND WOULD NOT ABSORB THE ENTIRE REPAIR COST. I WOULD LIKE TO KNOW IF THIS IS THE FIRST TIME THIS HAS OCCURRED WITH THIS MODULE SINCE THE 2013 RECA

No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
