“Odometer Fraud. The contact purchased a 2008 Toyota Highlander. It was discovered that there was a mileage discrepancy. The vehicle was a private sale. The contact stated that at the time of purchase the mileage was 106,000. After obtaining a Carfax report, the contact became aware that the mileage listed was 264,000.”
“My 2008 Toyota Highlander Hybrid is having severe issues with the ABS system. Toyota is reporting that it needs an ABS actuator and ABS pump replacements. These were a part of Toyota's previous Customer Support Program, but the program expired before I owned the vehicle. That is EXTREMELY dangerous and the issue with the ABS system should be considered a Safety Recall that is ALWAYS available to Toyota customers to rectify and paid for by Toyota.

The vehicle was a private sale. At the time of purchase, the vehicle mileage was 123,399, and at the time of registration, it was discovered that the mileage was 271,890.”
“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…”
“Air bag lights continue to show. Vehicle had not been in any accidents. Seat warms do not work light comes on when you turn them on. Driver window will go up half way occasionally. Back wiper motor makes loud noise and doesn’t work anymore. Tire sensor also comes out.”
