Piston Slap: A Self-defeating Technology Disorder?

Got a Mazda 3 hatch to replace my 29-year-old MR2, and while it’s no MR2, it has its own benefits. But I detest Hill Launch Assist, and the power steering is the biggest reminder that it’s no MR2.

The Mazda power steering is better than I expected, but it’s still the first thing I notice when I start it up and always makes me want the MR2 back, three years later. I tried turning the engine off on a private road with just enough slope to keep moving, and it’s kind of scary to imagine that happening on a freeway, it’s so stiff and jerky. Is there any way to disable it and having just plain manual steering, to see what it’s like?

As for Hill Assist, what annoys me the most is not knowing if a slope is enough to trigger it or not; if I expect it, and it didn’t engage, there’s a tire chirp for no reason, and if I don’t expect it but it did engage, I sometimes kill the engine unless I’m paying attention. I can understand its attraction for weenies who are just learning stick, but I don’t need it and don’t want it.

  • Theflyersfan I always thought this gen XC90 could be compared to Mercedes' first-gen M-class. Everyone in every suburban family in every moderate-upper-class neighborhood got one and they were both a dumpster fire of quality. It's looking like Volvo finally worked out the quality issues, but that was a bad launch. And now I shall sound like every car site commenter over the last 25 years and say that Volvo all but killed their excellent line of wagons and replaced them with unreliable, overweight wagons on stilts just so some "I'll be famous on TikTok someday" mom won't be seen in a wagon or minivan dropping the rug rats off at school.
  • Theflyersfan For the stop-and-go slog when sitting on something like The 405 or The Capital Beltway, sure. It's slow and there's time to react if something goes wrong. 85 mph in Texas with lane restriping and construction coming up? Not a chance. Radar cruise control is already glitchy enough with uneven distances, lane keeping assist is so hyperactive that it's turned off, and auto-braking's sole purpose is to launch loose objects in the car forward. Put them together and what could go wrong???
