| Description of the problem | Vehicle 4wd selector set to auto. Started vehicle. Vehicle 'service 4wd' warning light came on. Vehicle became stuck in 4wd mode. Vehicle difficult to steer or drive, and would not accelerate to normal road speed creating safety issue. Repeated shutdown and restarts of vehicle did not remedy problem. Had vehicle towed to dealer. Dealer service department said it was a known problem, and said they applied manufacturer software update that was issued. Dealer said that no official recall had been issued by manufacturer but a service bulletin and software patch had been issued. Vehicle returned. 'service 4wd' warning light still comes on every time vehicle is started despite software patch. Keep vehicle 4wd selector set to 2wd in fear that using 4wd or auto will re-engage 4wd and vehicle will be stuck in that mode - difficult to drive or steer, and unable to accelerate to normal road speeds. |
