Piston Slap: VSC Light and the Puffer Fish Effect?

Looongtime TTAC commentator PrincipalDan writes:

I recently had an experience with CEL (check engine light) and VSC light (vehicle skid control) that left me scratching my head: I was on my way into Gallup (30 mile drive) and as I was getting up to speed on the highway the CEL and VSC came on at the same time. I know the CEL can be triggered by a dozen different things but seeing a constantly lit VSC was a new experience.

The vehicle (2010 Toyota Highlander) drove perfectly normally and I went on to my destination. I consulted the forums and they said the CEL would AUTOMATICALLY trigger the VSC light and that the VSC would basically be shut off by the triggering of a CEL. Dafuq!?!?!? Really Toyota?

A CEL (which could be triggered by something like an improperly tightened gas cap) will shut down one of the key components of the safety systems of the car? What’s the logic behind this? More lights means the average American is more likely to go to the dealer and get it checked out? Do all of the manufactures do this now?

BTW, my lights were triggered by a bad gas cap. Couldn’t get it to “click” anymore so I replaced — lights went away and problem solved.

  • Brandon I would vote for my 23 Escape ST-Line with the 2.0L turbo and a normal 8 speed transmission instead of CVT. 250 HP, I average 28 MPG and get much higher on trips and get a nice 13" sync4 touchscreen. It leaves these 2 in my dust literally
  • JLGOLDEN When this and Hornet were revealed, I expected BOTH to quickly become best-sellers for their brands. They look great, and seem like interesting and fun alternatives in a crowded market. Alas, ambitious pricing is a bridge too far...
  • Zerofoo Modifications are funny things. I like the smoked side marker look - however having seen too many cars with butchered wire harnesses, I don't buy cars with ANY modifications. Pro-tip - put the car back to stock before you try and sell it.
  • JLGOLDEN I disagree with the author's comment on the current Murano's "annoying CVT". Murano's CVT does not fake shifts like some CVTs attempt, therefore does not cause shift shock or driveline harshness while fumbling between set ratios. Murano's CVT feels genuinely smooth and lets the (great-sounding V6) engine sing and zing along pleasantly.
  • JLGOLDEN Our family bought a 2012 Murano AWD new, and enjoyed it for 280K before we sold it last month. CVT began slipping at 230K but it was worth fixing a clean, well-cared for car. As soon as we sold the 2012, I grabbed a new 2024 Murano before the body style and powertrain changes for 2025, and (as rumored) goes to 4-cyl turbo. Sure, the current Murano feels old-school, with interior switchgear and finishes akin to a 2010 Infiniti. That's not a bad thing! Feels solid, V6 sounds awesome, and the whole platform has been around long enough that future parts & service wont be an issue.
