problem #2

  • Automatic transmission

Throttle becomes sporadic and unstable. Problem occurs once car has reached operating temperature and is restarted. This is a safety issue due to vehicle surging forward or not responding. Manufacturer has not resolved this issue even after several attempts.

problem #1

XG350 6-cyl

  • Automatic transmission
  • 5,500 miles
Car driven for 6 miles. Engine shut off for 1 hour. Restarted car and shifted to dive. Car moved forward without problem. Traveled 3/4 mile and stopped at traffic light behind some cars. Had right foot on brake pedal, car started to move forward, pressed pedal harder but car continued to move forward. Noticed rpms at 4000 without gas pedal being touched. Shifted to neutral, depressed and released gas pedal. Rpms at 3500 and dropped to 1000, rpms jump to 3000 and back to 1000, rpms jump to 2500 and back to 1000, rpms jump to 2000 and back to 1000, rpms jump to 1500 and back to 1000. This process took about 25 seconds. Put car in drive, all seemed ok very bad situation. ***note: Car temp was slightly below normal ****
