2008 TOYOTA HIGHLANDER Complaints

We were driving at about 40 MPH and approached our turn. When I depressed the brakes, they felt spongy and I had trouble slowing quickly. The yellow triangle illuminated on the dash and a long warning beep sounded. I was able to get safely parked in a parking lot, and my son came and took a look as well. We had the car towed to a shop, who diagnosed the problem, stating that we needed to replace the brake booster pump and actuator assembly. A family member noted that Toyota had issued a recall for vehicles with the same year/make/model for the braking system, so we had it towed to our local Toyota dealership to verify that they had no open recalls on the brakes and complete a full inspection otherwise. They validated that the brake booster pump and actuator assembly needed to be replaced. I am left wondering why my vehicle was not included in Toyota's recall.

There was a customer support program from Toyota for certain Highlander from 2008 to 2010. The deadline was in 2020. The same issue started for me three weeks ago. Local Toyota Service center confirmed that it is the same code and issue but quoted me over $3000 to replace the whole thing. Since Toyota admitted that this is a faulty part and had support program to replace the parts, there should not be expiration date on the support program. This issue can only be fixed by Toyota Service center since it requires specialized tool and software. Customer should not be forced to pay the excessive fees because Toyota used faulty parts in the beginning.

The brake pedal gave no resistance, going right to the floor. The ABS system warnings lit up on the dashboard at the same time. I was able to pull the car over safely, but it was not driveable and needed a tow to a repair shop. The repair shop noted that the brake actuator assembly and skid module failed and needed replacement. AFTER DOING RESEARCH WE ARE CONFIDENT THE ISSUE IS EXACTLY AS HUNDREDS OF OTHER OWNERS HAVE PREVIOUSLY REPORTED TO TOYOTA, BBB, AND NHTSA. TOYOTA HAS SINCE ISSUES RECALLS AND WARRANTY EXTENSIONS FOR THE OTHER TOYOTA HYBRID MODEL THAT UTILIZE THE SAME PLATFORM/SYSTEM BUT JUST NOT FOR THE LATER 2008 HIGHLANDER HYBRID. SOMEONE NEEDS TO STEP UP AND HOLD TOYOTA ACCOUNTABLE FOR THE SAME FAULTY PARTS THEY CONTINUED TO INSTALL IN THEIR OTHER HYBRID VEHICLES THEY SOLD TO CONSUMERS. THE ABS SYSTEM IS CLEARLY NOT FUNCTIONING PROPERLY AS HUNDREDS OF CONSUMERS HAVE PREVIOUSLY NOTED. WHY WOULD TOYOTA COVER THE COST OF REPAIR FOR OTHER HYBRIDS WITH THIS SAME DEFECT BUT NOT OTHERS? THERE NEEDS TO BE A RECALL OR WARRANTY EXTENSION ISSUED FOR THIS MODEL/YEAR AS TOYOTA HAS ISSUED FOR OTHER HYBRID MODELS USING THE SAME PLATFORM. THIS IS CLEARLY A WELL-DOCUMENTED PROBLEM FOR THE 2008 MODELS.

Intermittent warnings "Check ABS", "Check Brake System", "Check VSC System" have been showing up on the vehicle display along with the brake and traction control warning lights. This has been happening on and off for several months. Diagnostic Trouble Code reader shows "C1391 Abnormal Leak of Accumulator pressure".

The engine burns Coolant and yet doesn't overheat. The engine on cyl 4 misfires. Changing the head gasket didn't repair the issue, replacing all fuel Injectors and ignition parts didn't either. Heads inspected and passed. Compression testing passed. Always misfires on cyl 4. No repair aside from an ecu reflash or replacement seems to be possible. 4 shops looks at it and couldn't find any reason why it was misfiring and no traces of water were found in the interior, on the floor, in the oil or exhaust in the cooling system.

The ECU requires a reflash or replacement. The hybrid batteries over heat and regen braking randomly shuts off during braking or before/after due to overheating becuswe the cooling fans do not engage past level 1 or 2. The fans in fact never go full speed unless commanded by a Toyota service tech via the software during fan testing. Upon testing I noticed they not once went high enough to be audible and thus overheated. Manu forms indicate this is a common issue and requires 180-$300 for a reflash and/or replacement of the compu) ECU to alleviate this issue. Second issue I've found is the 3rd row seat belts just like some other MY Highlanders have their restraints cut at the shackle holding them to the body of the vehicle. I have seen several sheered this way including my own vehicle.

Myself, and many other 2008 Toyota Highlander Hybrid owners, have a vehicle code labeled C1391 "Leak in Accumulator" wherein the vehicles brake actuator and brake booster pump malfunction. The dash of my vehicle has the following indicators on; Check ABS, Check Brake System, Check VSC System, Yellow Master Warning Light, Red Brake System Light & Buzzer, Yellow ABS Warning Light, and Yellow Slip Indicator Light. This has been a significant cause of concern for me over the past two-three years since purchasing this vehicle. This is a known issue throughout the Toyota Highlander Hybrid community and the dealership is not upholding their previous recall which occurred in late 2019 and ended in 2020, after I had purchased the vehicle. The cost of repairs is upwards of $4,000 and Toyota has not given the proper opportunity for recall repairs to owners. This is a significant safety issue because if the brakes fail, a severe crash may injure myself or others. The problem has been reproduced by several other owners, dealerships, and independent service centers (this is a well known and common issue). This vehicle is available for inspection if requested. I plead that you please insist on Toyota reopening their recall to provide service to the owners of this vehicle, this is an issue with their manufacturing and not on the owners/operators. This problem occurred immediately after receiving scheduled maintenance to my vehicle from a certified Toyota Dealership, whom have quoted me the above cost for repairs and may have caused the issue in the first place.

The contact owns a 2008 Toyota Highlander. The contact stated while driving at various speeds, the front end of the vehicle was making an abnormal clunking sound. The vehicle was taken to an independent mechanic, where it was diagnosed that the entire subframe was severely corroded and needed to be replaced. The vehicle was not repaired. The dealer and the manufacturer were not notified of the failure. The failure mileage was approximately 175,000.

I was in a car accident yesterday two cars hit me from behind my daughter was in the third row and my other kids in the second row. The air bags didn't deploy and my daughters seatbelt in the third row didn't lock when the cars impacted my vehicle her seat belt kept going forward with her. Also my seat belt unlocked and came off upon impact of car

Brought this sport utility truck from a dealership out of Sandersville, Geogia in 2018. Never had an issue with this vehicle. All services are done in the dealership. It previously has 168k mileage. I have always heard sounds from as i have learned is the ABS motor\pump system since purchasing the vehicle in 2018, but never any issues. Now November 2023 this ABS situation has my whole dashboard lit up. This got full attention due we were traveling when this occurred to us telling me to stop the vehicle, pull over, shut the car off and contact a dealer. We exited the freeway at a gas station to see what the matter was about. I didn't since any tightness in the brake pedal so I drove back home to be safe. Warning messages read: Check VSC System, BRAKE Malfunction, Cheak Brake , Check ABS. I have not been able to get it fix due to the cost of the repair on an issue Toyota already knew about. It's our brakes Toyota. Has money over ridden the performance of these vehicle's? Safety for the customer is first, I thought.
