Shop recommendation on battery repair or replacement?

Got the dreaded "Check HV system Stop the vehicle in safe place". Had to be towed to Toyota dealer. I was informed that I need new plug-in HV battery. Price they quoted me is $12K. Before I decide to total my 2013 Prius Plug-in with 155K miles which has been absolutely reliable until now any recommendation on repair shop who works on Plug-in model? So far I am having not having much luck finding one. I live in Salt lake City. Thanks in advance.

 

Toyota dealer report shows I need to replace battery because 3 of the 4 battery packs have failed. Asked for codes they found on OBD scanner to service rep. Later on rep said a tech who worked on it saw these codes: P1A61, P1A67, and P1A67.

I am told replacing battery will cost $12k. One thing I noticed after they are done diagnosing when I starting the car for heck of it, which is still broke with same error message, I am hearing a loud fan noise from the battery pack I never heard before during entire time owning this vehicle. This blower fan being on full blast was never present prior to towing the vehicle to the dealer either. I asked them if they did something to cause battery blower fan to be on full blast continuously but they said all they did is hooked up the scanner for diagnostic. They said they all they did is cleared some faults and performed a safety recall for fuse (GGG85A H0R - Electric vehicle fuse fracture. 04007-1R147 M5 fuse kit).

Anyways now vehicle has been towed to another shop (independent hybrid repair) for second opinion. Trying to find shop who can work on plug-in model has been challenging.

 

I went though check out process up until last step of purchasing. It's not showing the shipping cost.

 

USD price is showing (minus unknown shipping $) is $6,488.46 from Amayama.


I did managed to find this shop in CA. Talked to them on the phone and they seem knowledgeable with Prius PHEV. They seem very skeptical that actual traction battery has failed as they see very far and few failing. They wont ship their battery to anyone however. They only work on vehicle at their shop and install upon their diagnosis. Pending second diagnosis with current independent repair shop I am considering towing my Prius all the from Salt Lake City, UT, to LA, CA.

1. Yes car was running perfect never had an issue. Driving home from work on highway 70mph with still 5-6miles (60% of total 4.4kwhr) EV range left. Error message popped up and car went into limp mode at 40-50mph with ICE engine shut off on it's own. Car did not respond to gas pedal only brake pedal was working. Got off on the next exit and when stopped the at the off ramp stop it would no longer move. Later on cop had to bumper push me onto street side walk since car was blocking traffic.

2. Typo. One of them should have been P1A64.

3, I did ask Toyota dealer to check the 12V battery but I didnt double check that if they did when I came to pick it up to tow to another shop. I carry a portable DeWalt jump battery in the car which was used to jump start when this incident occurred in hope that 12V battery issue but didn't help. I have not tried to jump start from another car however. I did remove 12v negative and and positive terminal for 30min which didnt help. Also white LAN cable (one that keeps showing up for HV error message for Prius on Youtube) that plugs into engine bay fuse compartment for 30 min which also didnt help.

 

I have considered that until I was able to locate a refurbished battery from Greenbean which they have to build for $2300 with a 2 week lead time. Since Toyota dealer and local independent hybrid shop both diagnosed a bad traction battery I've decided to go this route instead of towing my vehicle to CA to a HV specialty shop which would have been a wash if I consider the fuel cost for towing and renting a U-Haul trailer.

Honestly if wasn't for ridiculous current markup on new and used vehicles I would have totaled this vehicle and bought a hybrid of some sort. It has become long and lengthy process to repair this vehicle. I just hope when new battery arrives it fixes it. I just need this Prius PHEV to last another 2-3 years so I can buy a new vehicle as I am no longer confident that this vehicle will be as reliable as it has been considering its age.
