Piston Slap: Vapor Lock and the Hot R32?
Nick writes:I bought a used 2008 Volkswagen Golf R32 with 48,000 miles in January 2010 (5,000 only in the U.S., 3.2-liter NA V6). Every summer since then I’ve had issues as the weather warms up. Basically, it starts to act up when driving at around 85+ miles-per-hour or so, and it gets even worse if I’m stuck in any kind of stop-and-go traffic. The only sure fix is letting it sit and cool off for 30 minutes or longer.

Piston Slap: Buffeting Past the Helicopter Effect?

Scott writes:

Hi Sajeev!

I have a 2015 Civic, but my question applies to lots of cars.

I live in Maine, which has lots of nice weather for driving around with the windows down. The buffeting, or “helicopter effect”, with the windows down is driving me batty! Also the “white noise” of the rushing wind is quite loud when the windows are open. I can adjust the windows to limit both issues somewhat, but is there anything else I can do?

  • Ted “the model is going to be almost 4 inches longer and 2 inches wider than its predecessor”Size matters. In this case there is 6” too much.
  • JMII Despite our past experience with Volvo my wife wants an EX30 badly. Small, upscale, minimalist EV hatch is basically her perfect vehicle.
  • Dukeisduke Is the Volvo EX30 even on sale yet? It was pulled from the NACTOY awards because they were having software problems with the vehicle.
  • Wjtinfwb If you've only got 5k to spend on transportation, I cannot imagine a worse way to spend it than on a GM orphan from Sweden that's 15 years old with 150k on the clock and limited plus expensive parts availability and dwindling techs who'd even want to work on it. Go find a similar vintage Camry or Accord with 150k miles or even a Ford or a Chevy, whatever. Hell, even an old Jaguar is less of a crapshoot than a Saab. At least you can still get parts.
