When it happens

The middle half of failures fell between 41,089 and 65,000 miles, from the 28 reports that gave a mileage.

What owners wrote

“The headlights are ineffective. It is like driving without headlights at night. Had bulbs replaced but did not improve lighting. Moisture on inside of windshield. On cold evenings the inside of the windshield is frozen. March 21, 2024 the tailgate will not open. It appears this is a common complaint with this vehicle caused by drainage from the sunroof leaking onto the module that powers the tailgate.”

“Dim headlamps that are non fixable by installing new lights.. headlamp assemblies in the 2016 Cadillac SRX suffer from defective seals that allow moisture to accumulate and condense, therefore damaging and dimming the headlight bulbs.”

“The headlights incur condensation inside the headlight body, which makes the light from the headlights very dim. At night, this creates a very serious safety concern. 1. Other cars are not able to see you at night. 2. The driver is unable to see the road or other objects at night. There apparently was a lawsuit in 2 states on this safety concern, which they won. Please recall this, before someone else is killed.”
