Not ALL the G-35's require the brake switch kit, I have perfomed the install on both the coupe and the sedans. There are 2 different kits involved in the campaign. And yes the brake lights may not work if it fails and you also may have a check engine light illuminate. I'll copy the bulletin and post the VIN numbers tomorrow. We have had vehicles come in for persay the 7,500 maintenance and when the advisor keys in the VIN number, the campaign automatically shows up on the computer VIA infininet that the vehicle needs to be inspected under the campaign.
