Drive Start Control Malfunction - Visit Your Dealer

[ixo]

Got this yesterday morning... was a cold morning (in the Bay Area, CA... so not THAT cold) and I had leaned out the front door to remote start the truck. It started fine, so I walked back inside to get my boy ready for school. Five minutes later we come outside, and the truck is no longer running... that's weird. Get inside, start her up, and get the following on my dash:



Apparently "this is a thing", and sometimes comes with Grille Shutter errors as well (mine did not). It drove fine, but had me stressing, but took the son to school, and then straight to the dealer. I have just over 6500 miles. They kept it all day, then called me in the afternoon to ask if they could "keep it overnight... it feels like something to do with the cold weather, and they'd like to cold start it themselves tomorrow morning". I said "uh, sure" and am waiting to hear back today what they come back with. If this is truly "cold weather related" and I live in Antioch, CA, I can't imagine this bodes well for people who live in actual cold weather, like where it snows, etc?

I'll report back when they close the loop, but am hoping it's not some part that requires replacing that they simply don't have in stock, etc.

Ugh.

If it’s an early 2024, it may be the grille shutters. The earlier o rings on the electrical connection was to thin allowing water to get in and cause a short with similar error codes.

This happened to my early '24 around 400 miles. I unplugged the battery for 10 mins, it went away, and never has come back since. (25k+ miles)

Hope things get sorted out for you, im in cold country, ..knock wood no issues, i have a 24, i think it was actually a “last built in the 24 line, my dealer said it was in last run, i guess thats a good thing but regardless i hope things are corrected for you and you and your Taco are up and running soon

lol no, the first day they were "going to give me a lift home" but after waiting in the lobby for 30 min and noticing I was still not top of the list, I just grabbed an uber. Could have raised a fuss, but CBF

Same thing happened to me. Took it to the dealer and we checked the code on their obd2 scanner. This is what came up:

P0420: It means the Catalyst System Efficiency Below Threshold (Bank 1),

We cleared the code and it went away for good. (That was 4-5 months ago)

I have a 24' trail Hunter with 30,000km on it for reference .

Just to close the loop, they basically found nothing wrong, replaced the MAF, and called it a day.

I didn't expect a miracle, but they kinda wrote it up in a shitty way like I was demanding to have my vehicle back, so their hands were tied:

this was after they had had it for two nights, called me and told me they were at a loss, and there was no obvious fix. At every point in this process I told them "i mean do what you need to, but I'd like to eventually get it back" (again, no offer of a loaner or anything of that sort).

Full text:

Antioch Toyota. They're ... aight. Not terrible, but not going above and beyond by any means.

Anyway, I have it back, will repost if it comes up again, but just closing the loop here for y'all.

aaaand it's back.

I dropped it back with toyota, and this time they gave me a brand new highlander as loaner so that's nice

,

I mentioned to them that both time it has happened, it was during the "three click on the keyfob to remote start" the truck. Not sure if it's relevant, but we'll see. They'll probably keep it for a few days, and I'll report back if I have any news.
