NHTSA Complaint #11638865 — 2008 SUBARU OUTBACK

Due to a known manufacturing defect in the automatic transmission acknowledged in TSB 16-74-09 the driveability of my vehicle has been severely hampered and the shuddering/vibration is steadily worsening. I wasn't aware of this torque converter defect or an available remedy until well after the warranty expired as I didn't have access to the TSB. This is apparently a widespread problem affecting many vehicles of the era based on online forums and other complaints to NHTSA. I took the vehicle to dealerships over the years for related transmission issues but they "couldn't replicate" my concern. Recently, a local dealership has confirmed our transmission is affected but it does not throw any trouble codes or illuminate warning lamp as these underlying mechanical defects are not monitored by the OBD system. Having a gradually failing, defective transmission is a safety issue as we can grow complacent and it could give out any time without warning while driving. The vehicle is certainly available for inspection. It has been impeccably maintained, and none of these issues are due to mechanical wear and tear or neglect. It's unbelievable that a known manufacturing defect in the transmission would not affect every vehicle with that unit and be subject of a broad recall.
