My GX470 with only 22,000 miles on it was parked at the airport for two days and I started it last night to go home only to find that 4 warning lights were on. What does VSC trac mean? It feels like its driving fine so what does this mean? Just trying to see how serious this is. I know I need to get it hooked up to the computer but I am extremely busy this week. Is it safe to drive

The hoped for simple solution is a loose gas cap. Tighten the gas cap and will reset in about a day. When the happened to me rats had eaten the wires to the oxygen sensor. Dealer said it was safe to drive just idled rough. Insurance payed for repair

I had this problem but mine came on after I jump started my GX after the battery died. Cause is low voltage but also an O2 sensor failed. I hope your issue is just a gas cap issue. Good luck.

You can check my threads/posts for a more in-depth look at the issue. But I will mention something outright that nobody seemed to reveal to me until much later in the process of "scratching my head." The stability/traction control system disengages in sympathy to the check engine light. The presumption is that an engine issue can effect the performance of the stability control ... adding/removing power at the right time, etc. It's almost always reasonable to assume there is nothing wrong with VSC and related functions when accompanied by a check engine light.

If you don't have one, a good DTC reader will pay dividends, along with an O2 sensor wrench (the open end, flexible head variety, not socket). If codes specify or imply O2 sensor failure, you can probably replace them for 1/4 of dealer charges, especially using eBay. Denso is the way to go. If you've changed spark plugs on any vehicle, the O2 sensors are in your ability range. There are 4 sensors by the way, left/right pre-cat, and post-cat. Technically 2 are O2 and 2 are air/fuel. Just hope it's not a bad cat, because they are silly expensive. Best of luck.
