GMC Yukon XL AC condenser leak and intermittent brake light issues needing investigation on GMC Yukon XL

Some GMC Yukon XL owners report experiencing AC condenser leaks due to common issues such as refrigerant leaks, dirty or clogged condensers, or faulty compressors. These leaks can often be addressed by checking for blockages in the condenser and ensuring the cabin air filter is clear, as a low system pressure may require recharging and locating the leak source. Additionally, some owners report intermittent brake light activation, which can occur due to broken contacts inside the sealed housing, posing a serious safety risk. This issue has been widely discussed in forums, although GMC has not acknowledged responsibility. Owners experiencing brake light problems are advised to inspect the brake light contacts for damage and may need to replace the entire brake light assembly if the issue persists.
