My gal bought a certified used 2019 highlander. It now has 42k on it and the awd light went off. So i figured take it to toyota...check engine and awd..... warranty. Nope.... they say it's a bad purge valve and not covered under any warranty.

Anyway around the warranty denial?


Gonna be $300 and even if i do it myself they are gonna hit her $140 for diagnostic

Powertrain warranty is something like 36000 miles.

60 month /60K miles.

"Powertrain Coverage1

60 months/60,000 miles (engine, transmission/transaxle, front-wheel-drive system, rear-wheel drive, seatbelts and airbags)."

Still trying to find the 1 it lists.

Purge valve would be emissions equipment which should be a longer warranty.

This is what I would think. Purge should be warrantied to 80k

Every place I look online, that valve is not covered under the 8/80k.

"Specified major emission control components are covered for the first 8 years or 80,000 miles (whichever first occurs). The specified major emission control components only include the catalytic converters, the electronic emissions control unit or computer (ECU), and the onboard emissions diagnostic (OBD) device or computer.

They will warranty claim it to Toyota and still charge you.
Ask for the codes they pulled.

Unless I'm missing something. It's not covered. Listed on page 3-5 https://nepis.epa.gov/Exe/ZyPDF.cgi?Dockey=P100NNQH.pdf

What Emission Control and Emission Related Parts Are Covered by The Design and Defect Warranty?

An emission control part is any part installed with the primary purpose of controlling emissions.
An emission related part is any part that has an effect on emissions. Listed below are some examples
of parts or systems which fall under these definitions. A more complete list can be found in your
owner’s manual/warranty booklet. If any of the parts listed below fail to function or function
improperly because of a defect in materials or workmanship, causing your vehicle to exceed federal
emission standards, they should be repaired or replaced under the emissions warranty if your vehicle
is less than 2 years old and has been driven less than 24,000 miles.
One manufacturer may use
more parts than another, so the following list is not complete for all vehicles.
Emission Control Parts
1.  Exhaust Gas Conversion Systems: oxygen sensor, thermal reactor, catalytic converter,
dual-walled exhaust pipe
2.  Exhaust Gas Recirculation System: EGR valve, thermal vacuum switch, EGR solenoid,
EGR spacer plate, EGR backpressure transducer, sensor and switches use to control EGR
flow
3.  Evaporative Emission Control System: purge valve, fuel filler cap, purge solenoid, vapor
storage canister and filter

I don't see that it is covered. A warranty is a very specific list, not general ideas.

https://www.toyota.com/owners/resources/warranty-owners-manuals.highlander.2019


I can't speak to Toyota, but with Mercedes we have a program where you enter the VIN and mileage then the part and cause of failure. The program runs coverage, it's not a "decision" the dealer makes.

Many manufacturers disable AWD with various engine codes as a way to incentivize people to get them fixed.

Most OEMs have a warranty parts coverage check where they input the Vin, mileage, and part number/group number/base number and it comes back as covered or not.

Looks like it's not covered according to the posters above. Calling Toyota may get you some repair assistance but unlike the BS you'll read online the OEMs can't make the dealership do much of anything. If you can get some repair assistance from either Toyota or the dealer be sure to be grateful for it and not act like it was owed to you.

Your not going to get that covered by warranty.


It’s not a power train part.

It’s a 3/36 part. Most certified warranties only have a 1 year bumper to bumper warranty then are power train only.

An extended warranty won’t even cover it. It’s an excluded part in every contract I’ve seen.

Also the awd light comes on because it sets a powertrain code. Then the awd system sets a code stating there’s a powertrain code. It’s all part of traction control systems. They shut everything down when there is a power train issue. Don’t want to be doing funny things with timing and fueling for traction control when there are issues.

Contrary to popular belief that almost never happens. It's the easiest way for the oem to detect warranty fraud. Customers and sometimes even techs blather on about it when they are misinformed and thinking the man is out to get them.

Yeah I agree. People need to stop parroting that bs.

We get sealing spot checks that our dpsm where are goes Through 40 vin numbers.

Not to mention larger audits.

I would be surprised if goodwill was offered. You aren’t barely out of coverage, you didn’t buy the car new from that dealer and it’s a purge valve, not some extraordinarily strange or unexpected failure.

Purge valves and charcoal canister shut off valves fail, it’s just why they do. $300 to fix a CEL that disables AWD on a modern car? Sounds like you got lucky.

If something in the engine is not performing correctly system functions are limited. It’s not a scam to take precious money from your pocket.


Our vans have crappy wheel speed sensors. You get every single light in the cluster, there’s 7 or 8 modules that all store a fault for the sensor or for an implausible signal from another control unit due to the sensor.

That’s how CAN systems work. Single sensors with signals shared between modules. You don’t need a speed sensor for the trans and the engine and the wheel speed and the traction control and the awd. There’s one and they all talk. If someone on that network is unhappy, everyone can be unhappy.

Incorrect. There are different types of emissions warranty 2/24,000 and 3/36,000 and 8 year/80000 which mainly will cover cars and ECMs. The purge valve would fall under the 3/36.

OP you have a platinum agreement with every TCUV for 1 year or 12k from when you purchased it. Every Certified vehicle comes with that. If you are with in that timeframe it wouldn't hurt to check for coverage. Many ASMs do not realize that.

Been doing this for 19 years at various dealerships including 2 Toyota dealerships and have not once seen that occur. Toyota has access to all national history and can see when customers pay for service and when Toyota pays for it. They will see if it was double dipped. Everytime I seek goodwill assistance from my DPSM at Toyota he checks the National Service History.

It does.   Ours did it.  Its an easy fix but there are two kinds.  We have non hybrid but it used the same part. Was a little more expensive.   I dont think overall it cost more than 100 to fix it.

Wait till your torque converter goes out and it will


My advice.  Buy a scan tool that will erase the codes.   When evap valve fails it will die and not start.  It'll strand ya.  Or fix it.  Its right on top of the engine.

An emissions system giving a weird value and a wheel speed sensor have two entirely different effects on the drivability and safety of the car. Disabling AWD and other services for nearly every code thrown is certainly not required and yet some brands really lean into it. Don't tighten the gas cap on a Toyota all the way? No AWD or traction control for you! Better hope the service manager is having a good day and will good will the diagnostic fee on that one. Really depends on how many of those they've gotten that day.

Disabling the awd just means the rear doesn’t turn on, right? So you have a fwd car, like 90% of all cars Toyota makes?

Scary.

Traction control also gets disabled. Again, it’s a pretty dumb thing to do for a code for emissions and they’ve been doing it for ages, especially when the computers are smart enough to know the severity of a specific code and handle it accordingly.

Not a mechanic, but have experience with a few different different makes/models.  I have never seen a vehicle turn off TCS/ABS for powertrain codes. Misfires, lean conditions, vacuum leaks, emissions issues.

A purge valve not working correctly can severely mess with engine fuel trims.  Modern awd systems aren’t just about engaging a transfer case they also rely on information from the engine, so it throws an error code for awd saying that there’s and engine code.
