VSC (Vehicle Stability Control) & service indicator lights comes on in the dash regularly.
The car rides nicely.
The engine is adequate for the car.
The controls are easy to handle and operate.
The leather seats are not as comfortable as in other luxury cars.
But these sensors problem in this car has just started to give me and the Lexus technician a run for the money. No one seems to know what causes these indicator lights to come on. I have had to take this to the dealer 4 times for this problem in the last 1.5 months and still the lights comes back on in 100 to 150 miles of driving.
Check your brake fluid level/s then top it off above the max line. Drive a few miles and see if the VSC turns off.
If not replace brake pads with Lexus only factory part/s then rotors if necessary. Good luck.
I've had an '01 Highlander (identical drive-train) for six months, and have regularly had the VSC/engine check lights come on, then go off. There was no discernible difference in performance. Recently, the brake warning light also came on. I noticed the brake fluid level was at the Min. line; topped it off, and have driven several thousand miles since with no recurrence of the warning lights. I suspect brake pad wear (original pads, 64K miles; 75% worn) gradually put more fluid into the system. It seems to be sensitive to the brake fluid levels. I certainly hope it's as simple as that.
