are modern cars really maintenance free?

modern cars genuinely are better. quality surveys report fewer faults per vehicle than at any point in the past, and the difference is not marketing.

rust protection, engine tolerances, electronics and paint are all transformed. nobody adjusts a carburettor or changes points and condenser any more. spark plugs that once needed replacing every 20,000 kilometres now go 100,000 or further.

none of that made anything maintenance free. it moved the work.

what actually changed

intervals got longer. oil that used to be changed every 5,000 kilometres now goes 12,000 or more. longer, not never, and a longer interval means each one matters more, because a missed change is now a bigger proportion of the oil's life.

adjustments disappeared, wear did not. brake pads still wear out. tires still wear out. belts still perish. bushings and ball joints still develop play, and rubber still ages whether or not the car is driven.

some things got more sensitive, not less. turbochargers are hard on oil. direct injection puts carbon on intake valves where fuel no longer washes them. automatic transmissions marked "filled for life" have a life, and it is shorter than the vehicle's.

the real risk of believing the myth

it is not that a neglected modern car falls apart. it is that it does not, for a long time, and then fails all at once at 180,000 kilometres with a repair bill that makes the car uneconomic.

the old cars gave you warning. they ran badly for months first. a modern one runs perfectly right up until it does not, which is precisely why the schedule matters more than it used to rather than less.

where to find your actual schedule

in the owner's manual, and it usually has two columns: normal and severe service. short trips, cold starts, dust, towing and stop-start traffic put most Ontario drivers in the severe column, whatever their driving feels like.

we will tell you which one applies to how you actually use the vehicle, and what in the schedule is genuinely due rather than simply listed.
