Headlights problems of the 2011 Mazda MAZDA3

Mechanic's report 12/28/2019: "right front (passenger side) headlight assembly has major moisture contamination. Hid controller failure due to moisture; hid bulb out. Repair est. $1,500 - $2,000. " my 2011 Mazda 3 mileage is 36,915. I will take this to Mazda service dept. On 1/2/2020 for evalutaion. Their repair est. On phone was $2,000+ - parts only. This is a known problem reported online by many owners of this make and year. Clearly this is a factory defect issue. One that has caused accidents at night. (I first noticed moisture sometime after a drive-thru car wash 3 months ago. ).

Vehicle headlight failed due to faulty seal allowing moisture to enter the headlight assembly. I brought the headlight into the dealer while still under warranty when I noticed moisture in the headlight but before it failed. My claim was denied stating that it was a cosmetic issue. Now this is a safety issue that costs several hundred dollars to correct. Research online indicates many others have experienced similar warranty claim avoidance and failed headlight assemblies.

1) after moving the empty passenger seat back a few inches at a red light, passenger airbag deactivation light illuminated on dash and has remained on ever since. At the same time, the airbag light on the instrument cluster began flashing a code 16. There are no visible loose wires or connections under the seat. 2) condensation appearing in driver's side headlight assembly.

Passenger airbag light will go on and off with nobody in the seat. This happens randomly and not consistently. Sometimes while stationary, sometimes while driving.

Strange clunky noise from rear suspension, not consistent very random. Smooth road, bumpy road, fast or slow, the sound just randomly happens from time to time.
