How the mighty have fallen: the 2012 Honda Civic...

Timing chains still have to be replaced, don't they? Like every 100k miles or so.

I know on the Toyota 22RE the timing chain and guides have to be replaced, but I forget the interval.

Suzuki makes a point of noting that the timing chain on their cars is intended to last the life of the engine. Unlike the other cars, Suzuki will warrant a broken timing chain under the 7 year, 100,000 mile warranty: the other manufacturers call it a maintenance issue and won't cover either the belt or the incidental damage caused by a timing belt failure. I know that soured a lot of owners to cars that use timing belts, but most owners of those cars are NOT aware of the catastrophic nature of a timing belt failure in their cars.

A timing chain can fail, most assuredly, but at least Suzuki would cover it under warranty: the others pass the cost on to the customer. An engine with an 'interference fit' valve assembly that experiences a timing belt failure will crash the valves into the top of the pistons, causing a LOT of expensive damage to both the valve-train and the pistons. When it happens, most of the cars have 80-100,000 miles on them, and the cost of the repair will run thousands of dollars.

There may be some that fall in that range but I think for the most part timing chains are expected to last quite a bit longer.

I was checking both the service and the owners manual, and neither of them mention timing chain replacement.
Should be good for more than 100k miles

I think the goal of the chain is to outlast the rest of the engine.
