We haven't had any other reports of this issue here at Carsguide, so we asked Subaru for their help. They advised that they "have found that 'upgrade' headlight globes (brighter/ cleaner light) tend to have shorter lives. It seems that they have a trade-off between higher performance and longevity. This is true of genuine and non-genuine parts, although non-genuine parts seem to be worse as regards longevity. The recommendation is to buy standard genuine globes from the dealer, and try these." They added "starting the car with the headlights off will assist with longevity of the bulbs." In general, they said, "if there was a problem with the car's electrical system, such as an alternator issue, the problems would be more general and not restricted to the headlight globes only."
We have had a number of reports from owners of Outbacks and other Subaru models and, you would appear correct, it's not confined to the Outback. We have forwarded them on to Subaru for their investigation.
Anyone having problems with blown globes would be well advised to have the alternator output checked as suggested.
The biofuels people tell us to expect an increase in fuel usage of about three per cent, but that’s offset by the cheaper price of E10. Run a check on your car to actually measure the difference in consumption. Run it on E10 for a couple of tank fulls and then revert to regular unleaded, again for a couple of tank fulls. That will tell you exactly what your car is doing and if it’s worthwhile using E10. We have had a couple of other reports from owners saying their cars are using a lot more E10 than they were unleaded, but the biofuels people and the carmaker involved reckoned there was something wrong with their cars. Running a higher octane fuel will generally improve fuel economy and performance, but it costs more, so you have to balance the extra costs against the benefits to determine if that’s the best way to go.
We have received a number of reports from Outback owners and all report they have replaced a number of low beam headlamp globes.
There are a number of possible explanations for the poor seal that results in the noise. It could be that the car has been in a crash at some point and the door hasn't been adjusted properly when repaired; it could be that the door has dropped as happens on many cars over time, or it could be a faulty seal. Take the car to a body repair shop experienced in working on Subaru's and have it assessed.
Subaru's advice is correct and they confirmed it for us. The problems mentioned by the service manager are ones that might be experienced by owners of old cars, particularly those running carburetors. We also approached the Biofuels Association and they too confirmed that you could use E10 without a problem.
Take it to an independent Subaru service specialist who will be able to rebuild it, or have it rebuilt. We were quoted $400-$500 for a full rebuild, including new seals, and that included a two-year warranty.
The only thing you can do is put pressure on the dealer and Subaru to sort the problem out. Perhaps other owners can let us know if they have the same issue with their cars, and what they were told by their dealers.
