2017 Hyundai Kona Pricing and Specs

You haven’t actually told me what the shock absorber issue is. Is it a vibration, a lack of damping, a clunk? Either way, if there’s an issue with the shock absorber, then it should definitely be replaced, whether it’s linked to the strut-top bearing problem or not.

Best practice is to always replace things like shock absorbers in pairs. The same goes for suspension bushes, ball-joints, brake components, tyres and more. If they work as a pair, they should be replaced together.

I can understand why the crank angle sensor was the first thing to be changed. These often start to die and the first symptom is an engine that stops after running for a while. But you’re right to be sceptical about the timing chain as there’s a theory that says if the engine runs properly at all, then the issue won’t be anything fundamental. Which is to say, if the timing chain was stretched beyond the point at which the engine could function properly, it wouldn’t function properly at all, regardless of how long it had been running.

A good workshop should be able to scan the car’s computer. If the timing chain really is stretched, then the computer should have logged this as a problem. If not, then you’re looking for something else. Of course, what that something else is the million-dollar question. Don’t rule out basic things like a dirty fuel filter which can allow fuel to flow for a while before the rubbish in it clogs the flow after a few minutes running.

That said, if the engine can’t locate the correct signal from the camshaft (which is controlled by the timing chain) it will sometimes look for a stand-in signal somewhere else on the engine, allowing it to start but not run properly. An electronic scan is definitely the way forward.

These modern active cruise control system rely on lots and lots of information from around the car to function properly. And unless all those camera, steering, braking and throttle position (and more) sensors are playing as a team, the car’s computer - acting as the onboard relationship manager - has no option but to disable some functions, as they become potentially flawed without the correct inputs.

That’s why the connection between the power steering and the cameras on your car is so critical, and also why the systems have shut down. The actual failure could be with either the steering or camera system, but it will need a deep dive at the dealership to figure out what element has caused the shutdown of the other.

In any case, this is pretty clearly a warranty job (unless the camera has been damaged by hitting something) but you need to be fair about it and give Hyundai every chance to make it right.
