| Description of the problem | Vehicle shut off during driving, causing all electrical systems to fail including the electronic steering, which since vehicle also turned off, caused the steering column to lock up. Since the problem occurred at speed and infact while making a turn, a near collision occured. The problem occured multiple times in succession and was also intermittent with much time elapsing between episodes. Two other types of related occurrences during this timeframe were the (1) vehicle also cycling off and on and (2) would also turn on itself if the key was in the vicinity of the vehicle. Toyota of seattle experienced the issues when the vehicle was brought in and diagnosed the issue to be a loose bolted connection of the negative electrical wire from the battery to the frame of the vehicle. Though the vehicle has experienced similar issues since tightening of the negative wire bolts. Ongoing issues include the electrical system cycling off and on while driving including the navigation and front console display. The vehicle was bought in september 2014 and had less than 25k miles as of april 2016. On two prior instances electrical issues were identified and documented to toyota of seattle and the vehicle was kept for testing. The first electrical issue occured with the adaptive cruise control failing and thereby requiring passenger intervention to avoid collision. This cruise control failure first seemed to occur in december 2015. Toyota of seattle did not find any fault and sent me away. The second prior electrical issue of the battery prematurely failing occurred in march 2016. The readings indicated some odd draws. Toyota of seattle replaced the battery and sent me away without addressing the odd draws. The vehicle's safety remains suspect with ongoing electrical cycling off and on while driving. |
