So I got the flashing CEL, VSC, TC & Dealer said...
 

When I left work this evening I noticed my CEL, VSC, and TC On. Luckily I'm only 15 mins from dealer and they just looked at it right now.
The verdict......My engine wire harness has to be replaced :flame:. I know I shouldn't be mad since its under warranty but I'm worried about what problems may arise after warranty.

__________________

same issue here. it was under warranty as well. been fixed for like 6 months and no issues since then.

Was it your harness too?

yep.

Madness! Im just glad I was still under the 3/36k warranty otherwise I would
have been screwed!

Darn, the mileage on my 2008 is absolutely crawling due to my having repaired my previous ride and the cost of properly insuring the xB. It will be a most incredible drag if, after the basic warranty expires, I learn the "wiring harness" is defective and needs to be replaced. That, to me, would justify a class action suite against Toyota/Scion.

I've had a few friends who needed one of the coil packs replaced too along with that harness....

me too. when my car went bonkers they did both repairs. not sure if there's a service bulletin out on it. at the dealership i was the first with the issue.

Did ur dealer mention what caused the failure? Im now considering purchasing the extended 7/100k warranty before the basic one ends (Im at 28k now).

nope. i never asked. it crapped out on me and was repaired so i left it alone.

hmm...I'm glad I bought the 100k warranty. Too bad I'm already halfway to its end. If it happens it better happen soon. lol

Here we go again! Bend over and let the dealer tell you NOTHING! I want to know what they found and why the harness had to be replaced. I'm telling you that a harness is not a minor repair. If they are replaceing harnesses that much there should be a recall on them, extended warranty on them or some friggin explenation as to WHY they need to be replaced.

Ok, it is possible that the B has an ignition harness that plugs into the igniion module. That would not be a big deal to replace, but I have not had a lot of time to go over my engine that closely. A small harness and a coil or 2 wold not be that big of a deal, but when you say harness, I'm thikning the engine (or under hood) harness. That would not be a cheap thing at all, but some small section of harness would not be that big of a deal. You should ask them what they replaced, or at least ask them for the part # that they replaced. If nothing else, you should be keeping your records for future reference.

Lucky for me all my lights just kicked on. To bad im 5000 miles over my warranty!... so taking my xb to the shop tomorrow to get her looked at, lets hope this doesnt cost a lot (HAHA yea right)

It's the engine wiring harness....about 800 dollars.

I'd rather it be the engine wire however, rather then the engine room main wire. Those are usually in the thousands to get replaced. in our case the engine room wire is just over 2000 for the part alone.

The part has been "improved" and mid to late 09's and up aren't affected as they already have the improved harnesses.

I've got an early 08 and so far I've had NO problems with my wire so maybe it's a climate thing, kinda like the people that say thier e-brake cables freeze. I've never had that problem and I live in a wintery state.

for the record, most "extended warranties" on cars are damn near worthless. their coverage is usually crap. if you really look into it, very very carefully read and understand what it does and does not cover. most people think they purchase an extended warranty and think the whole car is covered until something breaks, and low and behold, it isn't covered.

for instance, just recently, my mom had a sidewall bubble on the side of her tires that she bought new just over a year ago. merchant's tire sold her a lifetime warranty, and for some bizarre reason, this isn't part of the warranty coverage. the woman only drives 20 minutes a day to the metro and then back every day. they said "oh, you must have hit a pot hole that damaged the sidewall and caused the bubble." so that isn't warrantied. i know a warranty is usually a guarantee against manufacturer defect, but when you sell one with a tire, usually you assume it'll cover some sort of unforeseen problem down the road...and it doesn't.

Thanks for the info, before I went to the dealer I didn't even realize this was an issue with the xb2. I'm not too upset anymore though, I've come to realize that this was the 1st year of a new model so there will be "bugs" with it.

I'm just glad the dealer has given me ZERO bs with the issues that have arrised (first the water pump and now this). Thumbs up to Toyota of Irving.

I dropped off my ride last night and this time I got a 09 corolla xrs (got an S last time). I dont know if this thing has been beat to hell but GOOD LORD the tranny is a mess. It shifts very rough in S-shift mode. If I drive regular in D mode and I just barely blip the throttle, the tranny is fumbling to find which gear to use. Also the gas mileage is now where near as great as the S that I got for a rental the first time but that is expected lol. (damn you, you thirsty 2az-fe motor!).

I hear what you're saying. If I even buy one its going to be a Toyota extended care one, not the bs ones you see on tv.

I'm still trying to figure out what the Toyota one is going to cover though....anyone have a link to show all that is covered with the 7/100k warranty through Toyota?

OK, I went to work and pulled this up from ALLDATA in the TSB (Technical Service Bulletin) section for the 08 XB. Seems the problem part is the whole eng harness and they have changed it for the 09 & up...

Seems not all the data copied over. But that gives more data to the situation at least.

I had the same issue about 6 months ago- Ignition coil: Primary / Secondary Circuit
According to service rep, it's a recall

No, it's not a RECALL, it is a service bulletin though. That means that they can find the fix for these codes in their system. It is covered under the 3/36 warranty. But not a recall.

Just picked up my ride and took a glance at the bill. Total was $994.xx :doh: Good thing this happened before the basic warranty was up!

Well I went to the dealership and they told me it was bc of my aftermarket intake. Which i can say that my filter my have thrown oil on the mass air flow sensor but this light came on b4 i put the aftermarket intake on. Either way i was still out of warranty and they didnt bother to say anything about a harness problem. I asked the service tech and he said he hasnt heard anything about this yet. So if it happens again ill just pay out of pocket for the harness i guess....

avoid a problem and put on the stock intake.

Thanks for the info, but I'd really like to know what the VIN number break over is. Also, the suggestion of the TSB is the coil pack "problem" is actually the fault of the harness, not the coil packs. Any further info available?

The Vin break is listed at the bottom of that TSB. any vehicles produced before that posted VIN can be affected.

What more info are you looking for? You'll not be able to find out what was changed as dealers don't even get that kind of info.

I hope this will help clear up some questions...

TSB # S-SB-0050-08 November 12, 2008

This TSB applies to vehicles produced BEFORE the Production Change Effective VINs shown below.

AUTOMATIC TRANS VIN# JTLKE50E*91067111
MANUAL TRANS VIN# JTLKE50E*91067112

That is correct for sure. If the problems match the TSB, they will replace it and play dumb.:confused:

SORRY, NOT A RECALL. The ONLY recall for the o8 Xb is for a little sticker that shows the GVW rating.

^^What he said....not a recall, just a service bulletin.

Thanks dude! Looks like I'm in the clear, though no doubt others aren't :(!

Perhaps I was less clear than I thought :( -- I'll repeat: "Also, the suggestion of the TSB is the coil pack "problem" is actually the fault of the harness, not the coil packs. Any further info available?" That is to say, I'm wondering whether the coil packs are a genuine problem, or just a symptom of the wiring harness issue. Thanks :)!

That is a GREAT QUESTION!!! I have been wondering about that myself. Toyota/Lexus/Scion coils are very good quality. An earlier post went on and on about the coil failures. In almost 9 years in our shop, replacement of coils in any Toyota vehicle has been rare at best. They just don't fail. So your question is dead on..... is it the coil or the harness problem looking like a coil? Hmmm....:ponder:

wow toyota has went downhill lately

I've been with Toyota for almost 9 1/2 years. In that time I've sold maybe 5 coils. usually because someone "thought" the outer boot on an old coil was replaceable and ripped it off. New coil designs do not have this boot.

I would guess that the harness is somehow damaging the coil but this is purely hear-say as I've got no proof of that. I figure that has to be right as generally the same location of coil fails on the xB.

Well I have a 2 week old rs7 and same thing just happend to me. So maybe they didn't fix this issue yet. Waiting at service now will post up when I find out.

^^^Ok, so what happened? Don't let them just say "we fixed it". Make them tell you what happened.

not fixed yet kept it over night

This has happened to my 08 about a year ago. First they replace the harness as per the tsb. Then a few weeks later the problem came back and then they replace one of the coils. Few weeks later same thing again and this time they replaced all four coils. It turns out since one of the coils were defective it caused other coils to fail also. Well that's what they told me anyways but since then it hasn't come back.

Well heres the verdict. The guy last night cleared my codes before the head mech could look at it today . So just going off those codes they say the wheel sensor got wacky from the snow. But he did say there was a lot of stuff in the readings that didn't make sense. Well first off i can live with a wheel sensor kicking off my abs aND TRACTION CONTROL and the cel. But heres my problem all waring lights came on at once when it first happend and the wipers stopped working elec steering stopped and lights dimmed. Shut car off restarted and then the abs traction light and cell came on. So im sure it will happen again. But hope it doesn't.

WOW! That's about all I can say....wow! Please keep us posted if things happen again. Sounds like there were way too many systems involved for it to just be coils. Something is up. What year modle is your B? Does it land within the vin codes listed in the TSB sheet? Did they record the codes they found? Wow!
