Tl* the contact owns a 2006 toyota highlander hybrid. the contact stated that the vehicle did not start and the hybrid warning indicator illuminated. the contact also stated that the vehicle was repaired three previous times by naguabo auto toyota (carretera 31 km 3.9, naguabo, pr 00718) regarding the hybrid module. the vehicle was not repaired again. the manufacturer was not notified of the failure. the approximate failure mileage was 150,000.

Intermittently, while driving down the road, all of the dash lights come on, there is a high beeping sound, and the brakes stopped functioning properly. the brakes either need to be matched with extreme force or the brakes will slam by barely touching the brake pedal. toyota acknowledges that this is an issue and offered a warranty extension to owners of this vehicle. i purchased the vehicle after the extension was offered and haven't had issues until recently. i am concerned for not only my safety but the safety of my family. i have been a toyota fan for all of my adult life. however, after dealing with this issue and being quoted $2000 to fix it, i would offer advice to anybody or not to buy a toyota or at least not a toyota hybrid. buyer and driver beware!

First a loud ringing happened and car would not stop. we have serviced car regularly, brakes are new, but car does not stop. trying to brake at the intersection, stop light and highlander would not stop. put us in danger almost led me into accident, was told it was the abs system and that toyota is aware of this. this is a huge safety design issue and expensive fix toyota needs to fix their design flaws. there is not physical contact or wear and tear on the part for it to fail. ms. deborah huston at toyota stone walls the process to get this resolved. she claims toyota is not aware of these issues, but the nhtsa records show customers have been complaining for a long time and that they know.

Car has 84,000 miles on it. after a 40 minute hiughway drive, car lost power and stalled. engine lights "check hybrid system" "check abs" and "check vcs" came on. towed to dealer, diagnostic check said the problem was with a wiring harness for the hybrid electrical cable, which suffered from corrosion and thus was leaking voltage. cost to fix minimum of $3500. faulty design??

2006 highlander hybrid, check hybrid system, check vsc light, brake and abs light all on permanently and my brakes aren't working. i was fortunate noone got hurt.. it was really dangerous when you press the brake and it doesn't stop. ... from what i read abs accumulator which cost 3k+ to replace and the hybrid inverter which cost 5k+ to replace. nhtsa please issue a recall on this issues.

I was pregnant and driving with 2 small children when the lights on my dashboard came on about vsc and a loud ringing happened and then i tried to brake at the stop light and they were so difficult to push i barely stopped in time to avoid an accident. was told it was the abs system and that toyota is aware of this but put stipulations on an extended warranty rather than recall so it's too late for most to get fixed and be covered. this is a huge safety issue and expensive fix toyota needs to stand behind.

While driving on the highway 65mph the vehicle lost all power,the check hybrid light was flashing, was able to pull over and stop. was able to restart vehicle and drive 110 mile home.

Abs system failed at 137,000 miles , mechanics stated this should never happen,i was driving when abs brake light came on and continues to stay on, and on 09/17 my abs and brake light is on,and when i push brake petal down , my car does not stop. unable to get car to come to a stop. i recently change my brake pads in august and everything was working perfectly untill septamber 20th 2017

I am about to purchase an 06 toyota highlander 4x4 hybrid. i received information that the 06 toyota highlander hybrid inverter has serious problems, and that the cost to fully repair this problem is huge. i would like to protect myself from potential problems (like this) by not purchasing any such vehicle. i would also like to know (if this issue is valid) whether dealerships have the ability to be informed of any such vehicle problems, before they sell it on their lot?

While driving on a major highway and in the fast lane going approximately 75/80 mph my 2006 toyota highlander hybrid died and failed to drive. the panel on the dash had a red ! exclamation point, and said check hybrid system and check vsc system. i was able to navigate my vehicle to the right breakdown shoulder to call for a tow. tried to start my vehicle several times and it would not start, but the hazard lights and instrument panel continued to light giving evidence my new 12v battery was functioning properly. called toyota motor usa and asked what recalls they have listed for my vehicle and they asked for my vin. they told me the electrical inverter assembly was covered for my vin. they gave me the number of a tow company to call and told me it was covered by toyota and i'd have a rental waiting for me. i had it towed to my local dealership as directed, they fixed several other recall issues but not this one, so when i drove off the lot the car died again. i managed to start the vehicle and drive it back across the highway into the dealership. after ...

While driving home from work in normal free-flowing traffic conditions on the freeway, several lights came on the dash indicating brake issues including vsc, abs, skid, parking brake light. continued to cautiously drive home, brakes seemed ok. had our non-dealer mechanic look at the brakes all were fine and had recently been replaced. he could not find a brake issue. took to the local toyota dealer and one code came up c1391 "abnormal leak in accumulator" and was told i needed a new brake actuator at the cost of $3273.00. diagnostic cost $138.00. additional information on diagnostic paperwork from dealer says, "check for dtc's found c1391, check for fluid leaks, could not find leaks, check accumulator pressure voltage (3.5 v), depressed pedal 4-5 times accumulator pressure drops below 3.0 v, recommend replace brake/abs actuator". other notes, some part of hybrid system seems to be cycling every few minutes. over the years, when braking, there have been times where they "jump" or don't grab during brake pressure and after reading have found this complaint with other owners. i see that the camry and the lexus have both had this part recalled/replaced ...

My wife and i were travelling on i-95 (southbound) towards richmond, va. my wife was the driver. we were steadily travelling at a speed... between 65 and 70 in the left lane (required speed limit). all of a sudden, with no warning, the panel lights started blinking and the power to the car was shut off. my wife was screaming because she was not able to control or effectively apply brakes. she tried and pulled car off the road barely and we pushed it off to a safe side. this could have resulted in a serious accident if we were travelling in the middle lane. the car was left overnight and towed to toyota dealer. the dealer called back and gave a quote of $10000 because the hybrid inverter have to replaced. i mentioned the recall on the inverter. the dealer said the recall does not cover my issue. there is a recall on your website -what action or recourse do i have. the original owner of the car replaced the inverter at 16200 miles. evidently all the 2006 inverters are defective. my question is this ---why your department is toyota ...
