The first thing to do is to give it a tune-up, with new spark plugs, replace the air cleaner, and clean the throttle body.

It’s not a common failure, and I doubt that Mercedes-Benz would contribute to the cost of repairs.

It’s a fine smear of oil, not a leak as such. It’s not something to worry about, unless it develops into a more serious leak.

Skipping oil changes is the worst possible thing to do, the oil will get thick and sludgy and the risk is that it will block the galleries in the engine, and in the worst case it could cause the engine to fail.

We contacted Subaru to see if there was anything further to add, and they told us that if you were willing to provide your rego and/or VIN number, they would check with customer relations. They added that normally, the first letter alerts the customer that the recall is pending and advises that they would be in touch when the parts are available, but without knowing what phase your car car is at, they couldn’t offer a definitive answer without investigating. I would suggest you contact the Customer Relations Team (1800 22 66 43) and give them the requested information they need to take it further.

The diesel will do your towing easier, and will be more economical as well.

Intermittent problems are hard to fix because the mechanic really has nothing to go when everything is working. It could be an electrical connection, or a sensor. The only thing you can do is to persist and take it to the dealer when it happens again.

 The problem models are from around 2010/2011. They are definitely ones to avoid, but you needn’t be worried about the 2015 model.

The shudder on take-off suggests a transmission problem, but the other issues are unlikely to be related to the gearbox. Get it to a Subaru dealer or specialist and have it checked out.
