Walmart then triangle RED light

I just don't understand why you are trying to trash the Scanguage, that's all.

 

I have a theory but it doesn't really pan out correctly.....this is with the 19 year old mechanic in mind.

Instead of draining the engine oil on the car, the mechanic drained the transaxle fluid.........but if he did that, adding 3.5 quarts of oil to your engine would overfill the car completely.....however if your car burned oil at 200k miles (which many do), it could easily have been 2 quarts or more low. So it may not have shown that it's overfilled by 3.5 quarts after filling.....that would explain the transmission not driving in D

crazy I know......

 

I think with a 20 year old this would be possible, this is probably a very likely situation considering that they had to check to make sure that they could do an oil change for a prius

 

From friends/family experience with damage caused by the oil change service itself at Walmart or damage as a result of handling the vehicle, they'll pay for repairs and costs of loaner vehicles.

If it was their fault, demand they reimburse you for your costs and that they pay for the repair.

Sorry you're going through this. :-(

to continue with my theory, you did drive your car home so the following has to happen.

When you were first done with the oil change, your car didn't drive. Brought it back into the bay and realized they drained the wrong fluid. They fix it by correcting the oil level, then adding Dextron transmission fluid to your car (they don't stock WS) to fill the transaxle. This would enable you to drive home but would quickly destroy that transmission and not allow it to engage into D.

ok, that should cover it.

 

I suppose anything is possible, but personally I find that very unlikely. They would have to be exceptionally clueless to confusing the transaxle with the engine sump.

More likely is just a simple overfill, as in drain the engine oil and replace it with too much. We've seen loads of cases like this report here on these forums. I'm not sure if it's something to do with the Atkinson cycle or not, but you don't seem to need much of an overfill on the prius engine to cause oil/fouling of the throttle body.

 

Yes you are correct, but I couldn't understand how he's not able to drive in "D". Mine was just a crazy thought during my spare time.

 

Well as I said anything is possible, but I wouldn't want to unnecessarily panic the OP that they might also have thrashed his transaxle too.

Remember that the drain plug for the ATF is a recessed hex (allen) key, so it can't be removed with a normal socket or wrench. For 100% certain the guy would be under there with a normal socket or impact and would have to go out of his way to search up the right tool to even access the transaxle drain.

Anyway, hopefully the OP will update us with the outcome soon.

Focus on one thing at a time. And the first thing is finding out what is wrong with your vehicle.

 

I agree he's full of BS. The 12 volt battery fully charged would only be at 13 volts, 15 volts would be a real problem, and the HV battery should be at 201.5 volts at leased. You have a right to all of the codes after all your paying for them.

It may have started with the oil overfilled and subsequent fouling of the throttle body causing the engine not to produce power, but after you continued driving it until it could go no more you might have caused problems with the hybrid battery. Also the 12V battery may have been weak to begin with and what with all the start attempts and hazards light is possibly toast too. This may be causing them problems with the diagnosis.

Too late now, but it would have been SO helpful in diagnosing this if you had payed attention to when the engine was or wasn't running and the SOC of of the HV battery (8 bar graph) during the time it was struggling. Also would have been helpful if you had have checked the oil level and condition yourself after a problem was first noticed, instead of just handing back to the clown who probably screwed it in the first place.

 

In that case he was referring to one of the NiMH module pairs, typically about 15 to 16 volts. If a module pair is at 8 volts then you'll be up for a new traction battery I'm afraid.

 

Where are you located? How much did you pay for the car? I don't think leaving it with the dealer is wise. But a car with 200k miles, especially a Prius, can have some high repair bills.

There may be more options for you. Just don't give it to the dealer!!

 

I believe Luscious Garage is in the Bay Area and they are the real experts in hybrid repair. They also will have more options for you in terms of what you can do.

How much do you owe the dealer at this moment? Before you go forward with the additional diagnostics for $160, you can ask for the codes they already pulled. That should point you to the right direction of the problem.
