2 Electrical System problem

Failure Date: 07/23/2018

Vehicle hybrid/engine shut off while driving. Various warning lights lit up including vsc, hybrid system, and check engine. I was forced to change lanes with the car off but moving at about 40 mph and pull over on a side street. I as able to restart the vehicle and continue my drive. The following day, even though the check engine light and all warnings had cleared, the car turned off again while I was driving and breaking at a red light. The car failed to properly restart after this second incident. The vehicle was towed to a Toyota dealership which specified that the issue is the hybrid inverter. The vehicle only has about 81,000 miles and according to Toyota a recall had already been performed on the intelligent power module for the inverter in 2014.

3 Electrical System problem

Failure Date: 02/16/2018

While driving my vehicle on the northbound I-405 at about 4:30 pm on Friday afternoon, the vehicle's electric engine shut-off with no warning or explanation. Dash lights were still lit and vehicle was in motion. Could not get out of traffic safely except with remaining momentum from the no. 3 lane of traffic. Electric engine would not power-up. There were no fuel or battery problems. The technician's test narrowed the problem to the DC inverter which was previously a recall issue. This recall doesn't appear to have been resolved, though the dealer claims it was. Thank you.

4 Electrical System problem

Failure Date: 02/15/2018

While driving 40 mph, my dashboard lit up with �brake brake malfunction�, �abs chevk abs�, and �check vsc system�. All dash lights lit up also. Drove to the repair shop and had codes run. No codes were present. This is related to the c1391 code that has a recall on 06&07 highlanders, and 08 camy�s. The front right of the engine is making a clicking sound every 20 seconds from the brake stabilizer. Just prior to this for the last 2 weeks, the vehicle has had difficulty obtaining a �ready� light. Battery has been pulled and bench tested, and all connections were checked. It would appear that in the last two months many 08 owners are presenting with this problem, with a range of proposed repair expense from $3,300 to $6,500. Seeing as this is a known problem with the 08 camry�, resulting in brake failure in both camry's and highlander, this ought to be a recall for both vehicles.

5 Electrical System problem

Failure Date: 10/10/2017

I was driving in 295 I hearing a sound coming from the daskboard and a light appeared stated need to check abs break system by dealer. I said to myself I'll have it check when I got home. I was doing 65 miles per hour, I was pressing break there were no break, pump the break several times, no break, I pressed the emergency break and thanks to the lord the car slow down and eventually stop. Apparently dealer asked me $5,500. To fix this issue and I don't have this type of money, and I'm still making payment on this vehicle can't even drive; I believe this type of issue should be a recall. I need help please!!!!! ribertm@yahoo. Com.

6 Electrical System problem

Failure Date: 08/13/2017

Car seemingly running fine. Vsc light, abs light and brake malfunctiom light come on out of nowhere. Told to tow to dealership. $3450 to replace abs actuator. Same part has been recalled in other years and models but not 2008 Highlander Hybrid. This repair is 1/10 the cost of the original purchase price of the new car. Car has 116,000 miles on it.

7 Electrical System problem

Failure Date: 07/19/2017

Vehicle was in motion, departing from parked lot. Vehicle lost all drive power, and instrument panel warning lights turned on. After shutting vehicle off and restarting, warning message to check brake system, and check hybrid system illuminated. Also all warning indicators activated in the guage cluster panel. Thankfully, we were not driving fast when the vehicle became disabled, otherwise it could have been fatal. Had vehicle towed to nearest Toyota dealership, where they advise "the power inverter assembly failed. " Toyota refuses to help, even though this exact problem has been recalled for other VIN numbers matching my vehicle. These are unsafe conditions and proves that Toyota has not done a thorough job of recalling all affected units.

8 Electrical System problem

Failure Date: 02/22/2017

I was driving to an off ramp when my 2008 Toyota Highlander Hybrid just stop in the middle of a very busy traffic! it almost caused a terrible accident. I had it towed and the Toyota dealership diagnosed it as an inverter converter problem and will cause me $11000 (yes, eleven thousand dollars) to replace it. This appear to be an engineering defect fault. Of all the warning in place it seems to inform the driver, such as the abs light, low gas gauge, low air, oil maintenance warning, why not the 'inverter problem detected, bring your car to the dealer now?'. I feel that Toyota is being irresponsible in designing a car that just simply stop in the middle of the highway or on any street without warning. This error is super dangerous and can cause innocent lives and Toyota should take responsibility in correcting the wrong instead of hiding behind the scene. I did some research and found that there are other such problem but their customer service said that my vehicle id number is not on the recall list. Who include my vehicle on the recall list anyway? certainly this is a problem after all it is affecting vehicles 2006 to 2012? please help.

9 Electrical System problem

Failure Date: 10/28/2016

The contact owns a 2008 Toyota Highlander Hybrid. While driving approximately 40 mph, the engine stalled and the instrument panel warning indicators flashed. The vehicle was towed to the dealer where it was diagnosed that there was water in the hybrid battery compartment and the compartment needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 120,000.

10 Electrical System problem

Failure Date: 06/15/2016

On June 15th, 2016 while over 200 miles from home on a family trip with my pregnant wife and 2 year old son in the car driving down a 2 lane highway with a semi truck behind us at approximately 45 mph constant speed our 2008 Highlander Hybrid brakes locked up, a warning tone sounded, several lights lit up on the dash including brakes, abs, vsc, (((!))), and /!\, and the car stopped completely in the highway with the engine still running. The lcd displayed several alternating messages about the brakes, abs, and vsc and also about needing to have the vehicle checked by a dealer. As our car was about to be smashed by a semi truck I pressed the gas pedal to the floor. The brakes were completely locked up, but fortunately the car inched forward at less than 5 mph with wide open/full throttle to pull off of the road before the semi truck could hit us from behind. The situation was terrifying. I have taken the vehicle to a dealer. They do not know the reason for the issue. They want $500 to trouble shoot and generate a repair estimate. It sounds like the abs actuators are commonly $3,000. I have noted many similar problems on the NHTSA website for the 2008 Highlander Hybrid and other Toyota hybrid vehicles in which the brakes, abs, and vsc lights illuminate and braking issues occur.

11 Electrical System problem

Failure Date: 09/06/2015

I purchased a new 2008 Highlander Hybrid. Though I had no problems, in November 2013, the inverter was recalled at 79,000 miles, and replaced. We had no problems with the car for the next 22 months. On September 6, 2015, the car stalled and could not be restarted. We had the car towed 55 miles to the dealership. Investigation of the car over 2 days was unsuccessful in discovering the cause. On September 9, I asked if it was the inverter. I was told it was not. The service manager had contacted Toyota, who recommended taking apart the hybrid system to look for “a shorted wire”. On Thursday, September 10, I was told that they found a wire, would but the system back together, and would take it for a test drive. On Friday, September 11, the car stalled and died on the third test drive. At this time, I was informed it was the inverter. The service manager agreed with me in feeling that since Toyota had taken out an inverter that was seemingly working fine, and replaced with one that failed in less than 2 years, that Toyota would “take care of me”. On Tuesday, September 15, I was informed that the cost for the part was $8800, and that the “regional service/parts manager,” offered to pay half of the cost for replacement. I was not happy with this offer, as it still left me with a bill of several thousand dollars for a part that failed in less than 2 years after the recall. At this time, I have not accepted the offer. I was told to call customer service. I was informed that because the regional manager had made me an offer, there was nothing else she could do. My frustration is that Toyota recalled my vehicle for the inverter. And I believe a bad inverter was put it the car instead. This current inverter, that Toyota told me to put in the car, lasted approximately 29,000 miles and 22 months. This seems like a far cry from the expected life of an inverter.

12 Electrical System problem

Failure Date: 12/02/2014

The battery is in new condition. While I was making a call in my car for 20 minutes, the whole system shutdown, the 12v battery had to be jumped and recharged. Concerned this could happen while driving etc.

13 Electrical System problem

Failure Date: 08/08/2013

I accelerated from a stop sign to 45 mph. Just as I reached speed I heard a pop come from the forward engine bay and got all different warning lights in the display. Luckily the vehicle continued to roll and I was able to get out of immediate danger. The light said check brake system, check hybrid system, and check svs. I got vehicle towed to a Toyota dealership were it took them 3 days to tell me it was the hybrid inverter which costs around $8500. After some research I found there are many other people out there having the same issue, so I called Toyota corporate and filed a complaint.

14 Electrical System problem

Failure Date: 07/23/2013

While at the Toyota dealer for service, the dealer took the car for a test drive prior to the service and upon returning to the dealer lot the car died - no power. Dealer diagnosed as a bad inverter, ballpark repair cost is $9500. Besides being a serious safety issue, I cannot understand how a modern car can contain a critical component that costs $10k to replace that has no maintenance in the maintenance schedule or other diagnostics to alert the driver of pending catastrophic failure that may strand them in an extremely unsafe location (I. E. Middle of the freeway). I hope that NHTSA investigates the 2008 Highlander Hybrid inverter failures documented on this site and Toyota is held accountable for this serious safety hazard and extremely costly defect.

15 Electrical System problem

Failure Date: 07/13/2013

We were accelerating under full power onto us 101 on the northbound onramp from CA 41 when the vehicle lost all power, power steering and air conditioning. Oncoming traffic was able to steer around us to avoid collision and we were able to steer to the side of the highway and roll to a stop on the next off ramp. Warning indicators hybrid system, brakes, stability control, and return to Toyota dealer. Towed to dealer. Dealer determined with Toyota technical assistance that inverter assembly (g92a0-48100) failed and needed replacement. Vehicle is out of warranty due to milage. We were charged $8244. 77 for a new inverter assembly plus installation. We were lucky to avoid an accident. This kind of failure is dangerous.

16 Electrical System problem

Failure Date: 07/07/2013

We had just passed through a tollbooth on a freeway and were accelerating to merge with traffic when the car shuddered and slowed and steering became difficult. A number of warning lights came on telling us to stop driving the car immediately and to call the dealership. There were three warning lights which were something like: 'check hybrid system', 'check brakes' and 'check vsc'. We were close to the median and were luckily able to pull off into it and turned off the car. When we turned it back on the car would not move forward or backward and we had to have it towed home. We have since had it towed to the Toyota dealership and they have told us that we need a new inverter battery. We understand that Toyota has had problems with this part in the past for the 2006 and 2007 Toyota highlanders and wanted to report the problem because ours is a 2008 Toyota highlander.

17 Electrical System problem

Failure Date: 06/27/2013

My wife and daughter were driving on a busy highway when they heard a "pop" noise from the engine. The car stalled on the road. By the grace of god, they were able to drift to the side and did not have an accident. Next day, the dealer informed that the issue was with the hybrid system - the inversion part. The cost for repair would be $11,000! we live about an hour from our workplaces and thus put a good many miles on our car - the 125,000 miles on the car put the drivetrain out of warranty. We have had all recall services performed at the dealer, and kept regular maintenance. Not once were we advised by Toyota that the hybrid system was showing wear and may be in need of service. There was no indication (warning lights, etc. ,) that the hybrid system needed attention - no fore warning at all prior to the incident. In doing research, we really got upset to find Toyota had recalled 06 and 07 models for the very same hybrid issue. We also noticed there are many people with complaints on the same issue in various online forums. To cap it off -- after the dealer told us the repair bill is $11,000, we were advised to discuss with a Toyota case manager. We did and their offer? $1,500 toward a new Toyota purchase. We were highly frustrated by this response. We feel they are well aware of the problem and should provide better warnings to users and better resolutions to the problem - and recall all effected hybrids!.

20 Electrical System problem

Failure Date: 02/14/2013

The car completely shut off when driving, without any warning! luckily, the driver was not rear- ended!! the car was towed to Toyota where we were told that the inverter needs to be replaced for $9000! the car is in otherwise great shape and has been serviced at Toyota regularly . The last check up was last month at 118,000 miles! this is exactly the same problem reported for the 2006 Toyota Highlander Hybrid, which was recalled.

21 Electrical System problem

Failure Date: 10/26/2012

My wife went to move the car and backed it up where it died. Car started rolling back the drive and stopped half on half off the drop off of our driveway. She had no steering and no brakes. I checked out the car and it said hybrid error call dealer. The car would not run. I had it towed to dealer and he called me to tell us the power inverter needs to replaced at the cost of 8,600. 00. I understand Toyota had a problem with their 06 - 07 highlanders for the same issue. Nothing on a car should cost $8,600 to fix without being in a major car accident. We should have been told up front how much this would cost to fix in the event of failure. Luckily she wasn't on a highway when this happened.

22 Electrical System problem

28 Electrical System problem

Failure Date: 11/15/2009

My SUV starts itself without anyone or the key fob being anywhere near the vehicle. It has done this at least 9 times and happens anywhere and at any time of day or night. It is too dangerous to park in my garage so I leave it outside all the time. Toyota factory nor dealer have offered any suggestions to correct the problem. I want it recalled or bought back. It is unsafe to have a car that does this. Car has done this since Nov 2009 that I have noticed.
