will there be any long term problems with just ignoring these lights and not seekin to repair them?


Asked by Jun 25, 2016 at 07:40 PM about the 2007 Lexus RX 350 FWD

Question type: Maintenance & Repair

I have a 2007 Lexus RX350 with 118k miles!  My check engine, vsc and trac
off lights are on and the dealer merely tells me it could be fairly expensive in
labor hours alone to try and problem solve this.  I saw on earlier threads to
disconnect both battery terminals to let the computers drain of electricity. I
did so for about 24 hours and when I reattached them the lights were off.
Now however, after about 4 days, the lights are back on!  Will it hurt to ignor
these lights?

I would not ignore the check engine light as it can led to more expensive repairs like catalytic converters and engine damage. The other light disable your traction and ABS so it won't have the same amount of control on wet surfaces or winding roads and it will take longer to stop in a panic situation. On a vehicle this old a dealer is the last place you want to go for repairs, a good independent shop can handle almost everything a dealer can and you get more bang for your buck, plus there are some that specialize in Toyota/Lexus vehicles. A lot of shops can tell you what needs repaired now and what can wait. HTH

Get it fixed as it may cost more to ignore it.

so you are asking if you can just drive a car without any maintenance?! no, no magic cars, yet-

Some auto repair shops test the "Check engine light" for free. I have this problem now. The repair shop charged me $129 to diagnose the problem--I didn't know about the free diagnostic checks down the street. The repair shop wants to charge me $2500 to replace both catalytic converters. I'm going to get another opinion tomorrow.
