Moisture in the Taillights? Read This First
Currently Applies To: ’09–10 RL
We’ve been checking into warranty claims for replacing taillights due to moisture inside. Those claims come mostly from TQI but a few are coming from client complaints. That moisture is reported as either fogging (really small droplets) or larger droplets.

The taillights aren’t sealed units. They’re vented to allow a free exchange of air, so in effect, they breathe. And this design isn’t unique to Acura; it’s used by a number of other automakers. Moisture in these taillights is just a normal characteristic. We’ve found that it doesn’t affect or interfere with their performance and it usually goes away after several days.

It’s not uncommon to have moisture in the taillights of newly arriving vehicles due to the high humidity conditions they’re exposed to in shipment. Whether or not it’s noticeable depends on how long the vehicles were exposed, how much humidity is in your area, and how quickly they got to your dealership.

The important thing to remember is don’t replace the taillights if you notice moisture in them at TQI; you won’t fix a thing and your claim could be debited. If you get a vehicle in your shop for a client complaint about this problem, snap some clear digital photos of the taillights and send them to Tech Line. We’ll take a look at them and let you know if it’s just normal moisture or if you need to replace the taillights and send us the failed parts for further evaluation.
