I spent weeks determining the best replacement HV battery option for a ‘12 with 130,000 miles. Settled on purchasing a local rebuild from a different model ($600) I was to use 20 modules in mine. However, I was outvoted by the lady upstairs. So we purchased a “geak” version with 3 year warranty for a total of $1800 (new 12v included). He came and went…..I test drove, only to have the “system warning” come back on. Barely made it home from a 19 mile round trip. I screwed around with my cheap code reader….clearing and re-clearing and…. For some reason I opened the hood and noticed the hybrid coolant reservoir was dry….topped it off….cleared the codes again. The next test drive was FLAWLESS!!!…….Until I got back and noticed the coolant puddle. I’ll see if I can find the leak (hopefully an easy to get to hose) later. Oh, the tech did ask me if I had it diagnosed prior to disassembly (remember I was going to do it myself). Conclusion — Read The Title of this post.
Update…..Can’t find the leak. Doesn’t appear to be an easy to get to hose. Will be making an appointment…..probably at the local Toyota dealer.
Have you checked the reservoir tank? I've seen people replace the OEM spring hose clamps with something else and crush the plastic barbs or connection tees - creating a leak after a few warm-up cycles or hot/cold seasons.
I haven’t, but I well. That said….I’m pretty sure it’s coming from the radiator area. I took the plastic ‘under guards’ off, just couldn’t find the start point of the leak. I may have to drive it (get it warm) and observe then. If it’s not a simple hose or tube, it’ll have to go to a garage.
OK….car went to the local dealership. Somehow, in the ‘text authorization’ (this is my lady friend’s car _ she made the appointment and “authorizations”) we ended up with the repair ($815 + $174 for the flush). We also got an air filter ($41) - I have a stack of these in my garage. We got a cabin air filter ($49) - I laugh at folks who pay for this service. We received an engine coolant system flush ($132). New spark plugs ($187) - I also have a set in the garage. All told $1560 dollars — nearly double the actual REQUESTED repair. All she saw was the quoted total = not the itemized breakout. Very disappointed in our small town dealership group. I did discuss “document fees” with them when I purchased the most recent of three cars. I mentioned they were becoming ‘citified’ They are now full on CITIFIED! This will be filed under the; Screw Me Once….Shame On You / Screw Me Twice….there ain’t gonna be a twice. Oh….and I drove MY ‘12 for 460,000+ miles without any of the above services except the air filter replacements (done in the driveway). I did write a GOOGLE review …. As they requested.
