Asked by Phil
We’ve just had an alarm "Service Vehicle Soon" in our 2016 Holden Colorado 7 Trailblazer. The car has done 7000km since the 120,000km service. We have been towing a caravan for about 3000 of those 7000km, sometimes on dusty roads. Could this be oil condition or air filter?
Answered by CarsGuide
27 May 2024The alarm you’re seeing is the car’s way of telling you that it’s been working hard and needs attention sooner rather than later. The on-board computer will be monitoring all sorts of parameters including the engine oil level and condition and the state of the air-filter element. Either of those things (and a large number of others) could be the trigger for the alarm you’re seeing. But it could also be due to the transmission being heated to a point where the computer says enough, or even an actual problem somewhere in the driveline such as a low coolant level.
The best thing to do is have the vehicle serviced as per its own request. The workshop might be able to tell you the cause of the alarm, but either way, maintenance is due. Towing a caravan places a lot of extra stress on the engine and transmission, while hot and dusty conditions also take their mechanical toll.
