I have a 2011 land cruiser lc200. While driving along today the throttle made a funny noise and kicked back rapidly and the brakes seemed to slam on and almost caused accident. The check psc light came on as did other lights in picture. Things came ok again for about 20 miles and.it happened again. The jeep wouldnt move but then acceleration worked normal. All lights still on dash. This happeded a few times over last few years ans seems revert to normal again. Any ideas ? V dangerous and disheartening. Thank you all in advance.
