to sell or not to sell

prius has 140k miles, did all the maintenance, egr cooler cleaning and oil catch can. Inverter fluid, trans fluid.
However My car was showing signs of a bad head gasket which got better with the oil catch can, but now I have my ABS lights and brake lights on.
Code cleared but came back on its own, my brake booster is going bad i suspect as it was pulsating few months ago but I ignored. So if I need to replace brake booster, hybrid battery, brakes, new shocks, I think its just a lot of work for a car that isn't worth a ton. This is with me doing the work myself as taking to a dealer would certainly make this an easy decision to get rid of.

brake booster $580 oem
brake master cylinder $580 oem
hybrid battery $2350 greentec
brakes $75
shocks $500 koni
Head gasket replace ?

what yall think?

 

Did a leak down test and cylinder 1 was about 5psi lower, can’t recall would have to look back on here when I posted about my HG issue.

brake have been making a pulsating noise when I’m at a stop, very faint pulsating noise otherwise brakes worked fine until recently the codes went off and now I get no brake booster or abs, making it unsafe to drive imo.

Shocks are necessary since I have trd springs and a large sub box in the back, since Lowering the car it’s more bouncy so I’d prefer some new shocks.

hybrid battery is around the time of replacement based off what I’ve read but I’ve never physically check the cells or used dr Prius app, but I will now ty. Also I run a heavy 2800 watts sound system and so I just imagine that’s put some wear and tear on the battery.

 

Yes I think I will go the new cells route

 

Oddly enough I was setting up tech stream last night and I go to start the car and while i was idle the code disappeared.

Update: ran tech stream and got the code of C1391 accumulator

Ran Dr Prius on battery and I have 49.88% health left, considered in bad condition but will run.

So, Cleared abs codes and brakes work fine but I definitely have to change out that accumulator because I can't keep clearing this code so often. I guess while I'm at it look into getting new cells for the batter pack and servicing it myself.

 

got a link to JDM guys? can't seem to find anything

 

Update:
Spoke with Toyota corporation asking to be a goodwill case and see if they can cover the cost of replacing my brake booster and accumulator(it’s recommended to replace both apparently) and they just said no I’m outside the campaign window for free repair. This is my first Toyota and probably my last, I know all cars have problems but Toyota Honda are supposed to be reliable on these sorts of things. Prius has so many dumb issues with it; but anyway I’m just going to fix it all since I don’t want to get a new car and I’m considering getting a new lithium battery from lithium project. The idea of better battery tech is all pluses in my book.

 

How do you guys feel about buying used brake accumulator and booster? I’m always hesitant to buy used parts, not unless I was just trying to flip it.

 

Well, I haven’t ever been on Prius nation but based off my research on here, I’m just going to fix the brakes with used parts and ride out the battery as long as the cells are holding decent voltage. And will just replace the shocks and struts. Overall that’s a worthwhile upgrade if I’m going to keep this for another 5 years or so. I’ll reevaluate the battery when the time comes.
