My car overheated suddenly, showed multiple warning lights, and was diagnosed as having a failure of the electric water pump --symptoms exactly identical to those described in !2v536000. My car did not stall but had the secondary conditions shown when Toyota engineers tested the likely results of failure of the faulty coil wire.
Afternoon 07/11/17 while driving downhill @ 50 mph my 2006 Toyota Prius turned off- no steering, exterior lights, dash/computer lights, radio- except for front interior dome light. No warning lights prior to or after car turned off. I was able to brake (very stiff brakes) & pull over. Replaced 2015 12v battery hoping for quick fix. Car still would not turn on, could not be towed on flat bad for fear of damaging transmission. Car was towed to closest mechanic. On 07/12/17 independent mechanic said both coolant pumps failed and the leaking shorted a fuse and turned off the car. Every time they attempted to replace fuse it would pop fuse again. Mechanic replaced water pump (including coolant/antifreeze) & inverter electric pump (including inverter cooler water) & changed auto transmission fluid & filter ($1,115). Early morning 07/14/17 dash display would not light up when car was turned on- no speedometer, odometer, gas gauge, reverse camera. (happened couple of times in past but could not duplicate for dealer. ) while driving to Toyota dealer I noticed computer screen stuck @ 48 mpg & 61 miles driven, but never increased miles as I drove 18 miles or updated mpg calculation. Refused to turn off car until someone from Toyota dealer looked @ dash to verify condition. Toyota dealer says combo meter (combination meter) failure, which is not recall but "campaign" that expired & repair costs $1,111. Motherboard part can take up to 3 weeks but car cannot be driven while Toyota "burns" my computer's information into new computer part. Toyota dealer provided loaner car until repair is completed. On 07/14/17 called Toyota & filed complaint about water pump & combo meter. Toyota says hybrid electric water pump campaign did not affect my VIN, which I do not believe. Toyota says combination meter campaign expired for my VIN. Pending call back from Toyota at this time.
The cooling system in my car is defective. The water pump is apparently leaking when I have committed no precursive action to cause it. This issue is related to the same issue in my other similar Toyota Priuses, where defective electric water pumps unexpectedly stop working. The other cars are consequently recalled and I believe mine should be as well. . Read more...
