2008 CHEVROLET EQUINOX with 48450.0 miles
Service air bag light is on and constant, preventing passenger air bag function. Retrieved codes are: B0081, B1370 and B0074. Needs passenger presence module part # 19207140 @ $533.33 plus labor and tax. I believe this part should not fail, especially when the passenger seat is used infrequently.

The airbag warning light comes on randomly. While lit the airbags will not function. It has been looked at by a Chevrolet dealer at least twice (12/2010 and 2/2011). Both of those times the error code was B0020. It has been taken to a certified mechanic on 8/2015 and codes B1370, B0081, and B0020 showed. The problem was always fixed, temporarily, by applying connector grease to the wire connections. On 9/2017, the mechanic replaced the passenger seatbelt retractor. This also fixed the problem temporarily. By paying close attention to when the warning light comes on we have determined that the sensor is affected by the interior temperature of the car. When the temperature is above approximately 65f the airbag warning light comes on and renders the safety of the airbags useless! I have yet to find any permanent fix for the issue. However there are numerous complaints by others online. It seems unacceptable to me that a vital piece of safety equipment is malfunctioning yet the manufacturer/dealer will not take any steps to fix it.
