A popular SUV with a known weakness
The Mitsubishi Outlander and its cousin the Eclipse Cross have picked up a lot of fans on Quebec roads over the past few years. They're solid, well-equipped vehicles that sell consistently well in the Montreal suburbs and across the regions. But if you own one of these two models, you've probably noticed something annoying: the headlights start to yellow or go cloudy much sooner than you'd expect. Sometimes it only takes three or four years.
This isn't bad luck. It's a combination of predictable factors, and understanding why it happens gets you most of the way to a solution.
Polycarbonate: a useful but vulnerable material
Like almost every vehicle built since the 1990s, the Outlander and Eclipse Cross use polycarbonate headlights instead of glass. Polycarbonate is lighter, more impact-resistant, and lets manufacturers create aerodynamic shapes that glass can't match.
But there's a trade-off. Without proper protection, polycarbonate degrades under UV exposure. Manufacturers apply a protective coating at the factory, but that coating has a limited lifespan. Once it starts to chip or break down, the plastic underneath absorbs UV directly, and that's when yellowing starts.
As we explain in our article on why polycarbonate headlights yellow faster than glass, this process is chemical and unavoidable without proper maintenance. The only real question is how fast it's going to happen.
Why it happens even faster in Quebec
Quebec's climate is rough on headlights. Extreme temperature swings in winter, road salt everywhere, repeated thermal shock between cold outdoor air and bulb heat, it all accelerates the breakdown of that protective coating.
Summer doesn't help either. Months of intense sun, parking lots with no shade at shopping centers and industrial parks. Owners who leave their Outlander or Eclipse Cross outside year-round, which is most people in the Montreal suburbs, expose their headlights to tough conditions for twelve months straight.
On top of that, both models have fairly large light housings with bigger exposed surfaces. More surface area means more coating to protect, and you'll notice degradation sooner once it starts.
Road salt is a particular problem. If you want to understand how much it affects your headlights beyond appearances, the article on road salt in Quebec and what it does to your headlights covers it well.
What you can actually do about it
First: don't wait until the damage is severe. A lot of owners put up with slightly yellowed headlights and figure it's not a big deal. But yellowing cuts into your headlight output, which becomes a real safety problem on dark roads at night or during a snowstorm.
If your headlights have been yellowed for less than two or three years, a professional restoration will get you excellent results. The process involves sanding away the degraded layer and applying a fresh protective coating. It's a different job entirely from picking up a kit at Canadian Tire or rubbing them with toothpaste. Those DIY methods sometimes strip surface oxidation, but they don't fix the root cause, and without proper protection applied correctly, the yellowing comes back fast.
Once the restoration is done, protection is the step most people skip. There are several options: wax, sealant, ceramic, PPF film. They don't all last the same amount of time. If you want a straight comparison, the article on wax, sealant, or ceramic to protect your headlights lays out the options honestly.
Mobile service: a real advantage
What stops a lot of people from getting their headlights restored is the logistics: scheduling an appointment, driving somewhere, waiting around, coming back to pick up the car. For a job that takes about an hour and a half, that can turn into half a day gone.
