There are 3 owner-reported lighting complaints for the 2014 Buick Regalin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Driver side HID headlight filling with condensation on lens and water collecting inside the headlight capsule where the wiring for the bulbs and ballast run through. Daytime running light now out and potential loss of headlight use is foreseen.
Driver side headlight assembly condensation. Heavy condensation is continuous and never clears up. No visible cracks or broken seals. Upon investigation, this seems to be an issue with Buick. There are numerous complaints among owners. The condensation diminishes the effectiveness of the headlight and limits the vision while driving.
Condensation inside both headlights. We didn't notice the problem until we moved from the warm west coast weathe to the midwest where the climate is colder.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
