Complaint Regarding DCM Module Failure in 2019 Toyota Highlander Platinum Our 2019 Toyota Highlander Platinum is experiencing severe audio system malfunctions, beyond simple Bluetooth and connectivity failures. The vehicle sporadically emits an extremely loud screeching feedback sound upon startup and at unpredictable times while driving. This deafening noise is highly distracting to the driver, posing a significant safety risk. Toyota has been aware of this issue for years and documented it in Technical Service Bulletin T-SB-0112-20, which identifies the faulty vehicle assembly locations. However, despite widespread reports from owners and the high cost of repairs, Toyota has failed to issue a recall. Given the clear safety hazards associated with this defect, I firmly believe Toyota should recall affected Highlanders and provide immediate replacements for the defective DCM module. Owners should not be forced to cover costly repairs for a known issue that compromises driver safety.
