Saw this on TIS's "new documents" tab when I logged in this week. Looks like there's an updated rear window glass for those of you who have run into randomly shattering rear hatch glass. So if you run into this issue, there is a superseded part number for the glass.

There is a Warranty Enhancement Program now for this condition, it's mainly for replacing/reimbursing owners who have had this happen to them.

I'm not understanding why there's a mention of "Applicable Warranty" in that TIS, a 4 Runner with this issue would be way out of the warranty coverage period regardless of mileage, so why would it even mention a warranty?

Since Toyota recognizes this as a defect hince the newly designed glass, is it possible they may do a Warranty Enhancement in the future as they did with the dashes?

@AuSeeker

It's possible if enough customers complain, push the issue it could become a Warranty Enhancement like the dashboards. I have not heard anything regarding that to be the case though (it'd be up to you the owners to create that momentum). In regards to the warranty period, it's posted on every TSB pretty much; not sure why but I guess it's just a standard thing for Toyota TSBs.

I wouldn't say that the part is "Defective" exactly, keep in mind that this issue is somewhat rare on the forum (I see it pop up maybe a couple times a year or so) and we're a very small subset of owners. Obviously it's been enough of an issue to be escalated to a TSB, but a superseded part does not imply a defect, merely that the new part is improved over the original. These rear glasses have basically been fine for over 10yrs in some cases (mine included), perhaps the superseded part is to address an issue that develops over time outside of the expected life expectancy of the vehicle? I can't say for sure, just trying to point out that a TSB and/or superseded part does not inherently imply a defect in the original part always.

I got a letter in the mail about a warranty enhancement program -ZG7 that covers the back glass shattering.

@Slowgoat Thanks for mentioning that, they must have released the ZG7 WEP recently after the TSB as I didn't find any mention of it when I made the thread. Updated the original post with the WEP notice as well.

Basically this is pretty cut and dry, if it shattered on you when using it; then you're covered.

No problem @BlackWorksInc .

Thanks for all you do around here, man.

Thanks for posting this. Wish I read it yesterday though! I was toggling the rear defrost all the way to work this morning in the snow, paranoid that it was gonna blow. At least this way I know I'm covered.

So in reading the Warranty lingo....it mentions 9 years? So is this from the TSB or production of the vehicle. In short is my 2006 covered still now, or if it blows until 2018 it is covered by warranty?

Basically all 4th gens fall under the "Primary" warranty coverage until April 30, 2018, regardless of mileage. After that it falls under "Secondary Coverage" which at that point means none of them are covered because the newest 4th gen is already 9yrs old from DOFU (Date of First Use), so what they're really saying is "you have until April 30th, 2018 to ask for reimbursement and/or get replacement of a shattered rear window due to defroster failure; after that you're on your own."

Looks like I need to use that every morning until April now . .

For some reason I thought this was cold weather use problem, i.e. heating up the rear window in freezing weather, but it is more accurately an electrical problem occurring in warmer or all climates...?

The WEP listed 2 part numbers 68150-35400 and 68150-35410.

I assume one is tinted and the other is not? can someone confirm. If so I need the tinted part number if anyone could help me out.

Prices are $430 plus ($100+) shipping online YIKES!!! My glass shattered this Monday which is way past the April 2018 deadline. I doubt any dealer would be willing to help me out to get this covered.

Thanks!

You could try calling a dealership for a quote and getting clarification for the part numbers (i.e. "Hey I have two part numbers for my vehicle can you tell me which one applies?")

You could also see if a website like Partsouq.com or similar Toyota parts website that lets you search by VIN will help narrow it down.
