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.

  • Wjtinfwb 157k is not insignificant, even for a Honda. A lot would depend on the maintenance records and the environment the car was operated in. Up to date maintenance and updated wear items like brakes, shocks, belts, etc. done recently? Where did those 157k miles accumulate? West Texas on open, smooth roads that are relatively easy on the chassis or Michigan, with bomb crater potholes, snow and salt that take their toll on the underpinnings. That Honda 4 will run forever with decent maintenance but the underneath bits deteriorate on a Honda just like they do on a Chevy.
  • Namesakeone Yes, for two reasons: The idea of a robot making decisions based on algorithms does not seem to be in anyone's best interest, and the thought of trucking companies salivating over using a computer to replace the salary of a human driver means a lot more people in the unemployment lines.
  • Bd2 Powertrain reliability of Boxer engines is always questionable. I'll never understand why Subaru held onto them for so long. Smartstream is a solid engine platform as is the Veracruz 3.8L V6.
  • SPPPP I suppose I am afraid of autonomous cars in a certain sense. I prefer to drive myself when I go places. If I ride as a passenger in another driver's car, I can see if that person looks alert and fit for purpose. If that person seems likely to crash, I can intervene, and attempt to bring them back to attention. If there is no human driver, there will probably be no warning signs of an impending crash.But this is less significant than the over-arching fear of humans using autonomous driving as a tool to disempower and devalue other humans. As each generation "can't be trusted" with more and more things, we seem to be turning more passive and infantile. I fear that it will weaken our society and make it more prone to exploitation from within, and/or conquest from the outside.
  • JMII Based on the human drivers I encounter everyday I'll happily take my chances with a computer at the wheel.The highway driver assist system on my Santa Cruz is great, it can self drive perfectly in about 90% of situations. However that other 10% requires you to be in control and make decisions. I feel this is the problem with an AI driving a car, there are times when due to road construction, weather conditions or other drivers when only a human will know what to do.
