Engine issues?!?!

Don't touch shit. It's under warranty and anything you do they'll likely spin back to you as a reason to invalidate warranty coverage.

Don't listen to any other advice, there's nothing else you should be doing except waiting for a service center to open.

 

No need for the tinfoil hat.
The check engine warning light only flashes for a serious misfire. As far as I'm aware, no other engine problem or event makes that happen.

Common causes are a sparkplug that is no longer firing, a coil that is no longer creating a spark, a failed injector or a loose electrical connector. Sometimes I've seen cars have a similar misfire issue following significant rainstorms, where some moisture becomes present.

It's your car, you're allowed to open the hood and wiggle some wires, check spark plugs, etc. You're also allowed to have it looked at by a shop other than Toyota. A misfire is usually a pretty basic thing to troubleshoot.

 

Terrible advice right here.

Exactly why I say don't listen to anyone and just wait for service center to open.

Toyota techs, FROM MY EXPERIENCE, are barely above an Autozone store employee in terms of their ability. Any decent tech is smart enough to not stay employed at a shitty dealership leaving only the idiots who can barely follow instructions. And they'll use any excuse they can find to turn warranty time into full book time. Even if it means lying (ask me how I know). All they need to find is some witness marks inside the engine bay that someone's been in there messing with things and they'll do whatever they can to make sure it's not warranty covered.

Do not touch anything even if you know what you're doing. Just because you're ALLOWED doesn't mean you SHOULD. Once the car is out of warranty then yeah, go all out and start pulling coil packs and plugs and send a boroscope camera down into the cylinders and do all the fun stuff.

 

tin....foil....hat
Well, not everyone has had your incredible experience. Warranty LAWS allow shops other than Toyota to work on cars. The guy says it's his ONLY car, and it's Thursday. You're asking him to do NOTHING until Monday.

Nowhere in my post did I say go all out and start pulling coil packs and plugs and send a boroscope camera down into the cylinders

You're acting foolish. Why don't you take your car to him so his family has something to use?

 

Yeah, sure, Magnuson-Moss Warranty Act exists. SURE. Doesn't mean they aren't gonna give you shit and try to get out of warranty time so they can pad their own wallet. Is it REALLY worth it to potentially have to argue with service techs and the warranty dept over some bs just because you wanted to check your spark plugs?

What do you really gain from doing that? Oh, you pull the plug and find that it's fouled or that the electrode is missing or damaged. You still have to wait for service dept to find the root cause and if the plug is damaged in some way they can even claim you did that when you were removing it.

It's just not worth it when you have active warranty coverage.

And this isn't me saying that people should never work on their cars. I did my entire aftermarket audio upgrade myself. My car before this one was a early 00's beater that I pulled apart and fixed. But there is nothing to be gained by going under the hood of a vehicle under warranty. Leave it to the braindead monkeys are the dealership so that all liability falls on them, not you. Don't advise people to risk their warranty, simple.

 

Take a flashlight under the hood and look for rodent nesting/damage. Obviously don't break anything, so you don't void your warranty. That'll give you a better idea. DO NOT erase anything, reset anything, or disconnect the battery, you don't want to accidentally erase any codes. Rodent chew marks is one of the only way for the dealership to void warranty repair work, so you want to look at that first. The dealership is probably open today, so you can probably drop it off and have them set you up with a loaner. Good - Excellent dealerships usually do that for a new car that fails under warranty, kinda like an apology. We're assuming your within your 3yr/36K mile bumper to bumper warranty.

Good Luck......

 

One thing you might want to ask nicely for is the Techstream Vehicle Health Check Report, hopefully they'll be nice and provide it.
The solid check engine light mean to me there's a pending code.
I'd want confirmation of that code.
Besides, the Vehicle Health Check Report might not have the Toyota DTC included in it, depending on ( if and when they run ) the techstream all systems health check.
There's always a chance that just clearing the code will fix the issue, whatever it was / is.
If there is a more serious issue going on, it's nice to have at least some documentation of it.
Hopefully it's not related to the 12 volt replacement you previously had to have done.

I'm not the best person to listen to when recommending what to ask a dealer for when there's a problem with a new car.
So take my advice with a grain of salt.
Even if my idea may be a good one, convincing a service writer or shop manager of that might not be so easy. Which would also point to the competency of the dealers service, the way I look at it, anyways.

 

soy based wire insulation and a warm engine compartment is a rodents dream. you obviously haven't see the rats in NY city.

 

Many places in Canada have December 26 (Boxing Day) as a holiday too. Just because Us dealerships in California may be open does not mean a Canadian dealership will be open today.

Many stores in Canada have Boxing Day sales that rival the US Black Friday sales.

 

I did say "probably", so your saying that no dealerships in Canada sells cars on Boxing day? I was just pondering alternatives to Uber's and renting a car over the long weekend, since that was his only car.

 

Is there really a 3 year 36K mile warranty bumper to bumper on the PP XSE ?
Does it really cover everything from bumper to bumper ?
Like wind shield wipers, only item I can think to ask about.

 

What were the specific codes?

@Drew_priuschat: how exactly did that unfold; your reader gave you a code, say P0302?

 

I could about guarantee tires would not be covered. Toyota likes to punt that to the tire manufacturer.
