ZB LT Sedan 4 cylinder 2 Litre Petrol Turbo
I bought a demo Holden Commodore ZB 4 Cylinder 2 Litre Petrol Turbo in early April 2019. In a word the car is brilliant.. very very quick, very agile, comfy driver seat, very solid on the road with outstanding brakes and grip. In this wetter weather I have seen a condensation build up on the back inside window mainly .. a little on the rear passenger window too. I have felt around the rear inside window and in the boot but found nothing. I am wondering whether it is the break light set up at the top of the rear window where a little water may have ' seeped in ' there due to see and rain. On a couple of occasions I have also used the pressure sprayer at a car wash place here in Beechworth. ???? but am sure the windows were closed. If they were not fully shut, can any even slight build up take a fair while to go away? Of course I checked (well i think i did) whether all the windows were fully closed when I found the build up on the last occasion. But the condensation build up us not lessening so that tells me that it us a problem, is me a fault .Can anyone help me, and do they know what strategy I can take b4 I take her in?. And what can Holden do? Because by the time I arrive for a service, the condensation wilk have gone. Of course I am looking for this to be fixed Also, is the Holden equipped to undertake some more sophisticated problem solving and techniques to get to the cause Your advice would be greatly appreciated Maybe other owners have this problem. I am inclined to think that that rear light at top of window, or the 'lift back, architecture . I call it ' hatch back is the problem???
This raises the question whether service managers have a database that shows problems wuth warranty issues in particular and the remedies taken. These are qyestions I will raise . I'll initially go back( speak to) to Patterson Cheney Vermont where I bought the car, and go from there I guess

Certainly take pics of it under different conditions..with or without pressure washer, different times of day etc...doesn’t matter if it has gone away by the time you take it in, so long as you have evidence logged.

Any car will have condensation depending on the weather.
TURN ON THE AIR CONDITIONER.....problem solved.....you see so many cars driving around with windows down in 38c temp....they thing they are saving on fuel......FALSE.

^^^ Agree, condensation is caused by warm moisture laden air contacting a colder surface.
When this condensation appears on the rear window and passenger rear side window are you carrying a passenger/s in the rear seat?
Try turning on the rear window demister, that is what it is for. Problem solved.

ZB LT Sedan 4 cylinder 2 Litre Petrol Turbo
sorry, I never answered this. I have done 15000 and wear is good ie quite normal . I’m not hard on cornering even though the 2 litre petrol turbo is so very lithe and agile. The low kerb weight of 1520 kg is a preventative iI think.. similar to us, if you are too fat, many things can go wrong .
I believe the VXR is not good on tyres ... or some of them
I’d be interested in looking what the kerb weight of the vxr, is, and I suspect that the AWDs of the zBs are not right

Sport Contact 5's on my Calais V. Serviced last week @ 13,500 km's and measured tread depth was 4.5mm fronts and 6.0mm rears (before being rotated by the service staff).
These tyres do not have a good rep for longevity so I am very happy with those tread depths.
We can also learn something interesting from this about the car's AWD system. Its mostly front wheel drive unless the car's sensors detect some form of slippage in which case it goes into AWD mode.

Don't ask me how the torque vectoring works front to rear when driving aggressively in terms of front / rear power split as I don't know, but it does seem to be a very effective system and rounds up corners extremely well.

I’m fascinated, all those who bleat about how they hate fwd yet unless your pushing the car, you’ve got fwd operating in most situations! I saw a Vid by a pro reviewer of my car and his claim was that fwd was actually better for handling and feedback, and safety, and torque steer was no issue on the 4 turbo. I’ll never get awd,it adds weight, complexity, and dough. There is obviously an issue with tyre wear for the VXR, and that has AWD, dunno about the other sixes.
My research paid off.

ZB LT Sedan 4 cylinder 2 Litre Petrol Turbo
thanks for that link, I haven’t seen it before. I agree, there aren’t any losers.

I can’t recall whether it was you than sang the praises of the LT, but I think it was you who asserted that the LT was quicker, handled better, and I think you said it ‘it is better’ than a Commodore VF 6, yet the respective kw were 191 and 235. You poured on the praise. It we only talk about Commodores pre 2018, the site will become extinct, boring as each model ages.

Disappointingly, the Moderator has shut down a couple of threads, but many other old ones are still open

I would have thought that continued discussions about the ZB and Holden are healthy because, if nothing else, we are going through the GM Holden divorce. The more we find out about the ZB, the more we realise that the paralysis of Holden told us subtly but deliberately, that no praise would go the the ZB Commodore, when in fact it deserved very high praise as a widget. And in discussing these matters, the more rich we are, and the more rich the history is. The windows of opportunity close quickly. This happened to Holden, and GM.

One of the beefs I have with Holden has been their profligate spending on the Arcadia just to give one example; it was in your face all the time for some months, with not an iota of content. It was shameful, an indictment on GM and Holden senior managers. It was akin to the abject wastage of money of Michael Bloomberg on advertising, trying to get the nod as the democrat candidate for the next Presidency.

I never saw any TV ad on the ZB Commodore. If I was owner CEO/Director of a Holden franchise, once I learned how damn good the ZB was as a widget, I would have fronted Holden executives, shown them the reviews and pressed them very hard to fight back for the ZB.

Since I published this post, I learned that franchise owners (some of them) put their languid energy into selling run out VFs largely because they made more dollar. Yet they ignored running with promotion of the ZB despite the excellent plaudits it was receiving with pro reviewers. In other words, they had a very very worthy car. It tells me that Holden head office were asleep at the wheel, and franchise owners cared little about having a great car.

It seems that they, as a group, didn’t have the right DNA to be the hands on CEOs who demonstrate passion for individual cars. Rather it would seem that their interest was only in seeing end of month sales, with little ‘love’ for anything else. Such a crying shame. And when you look back at advertising for the ZB, Holden spent zip on ZB and threw good money away on an Arcadia which was perhaps both the worst and annoying ad I have ever seen

I was told by Car Advice that there was no more passionate advocate for Commodore than Holden Director of Marketing, Aquilina. I don’t accept that at all, it’s bunkum because I saw no TV or other marketing campaign and plan to promote the Commodore at all, particularly late in 2017, and after that too. There was ample excellent info available to hail the quality of the ZB and fill the boots of the public. The lazy Holden executives sat back and did nothing.

Their ability to do something special would have hinged on having Opel on board to work with Holden to bring forward an even better Commodore in 2021. The tumult in the Auto industry with ownership change and Tesla’s staggering stellar emergence, killed off everybody’s energies.

Of course the ‘not off the bitumen’ dumb SUV buyers were the threat, and the tumult of the beginning of the electric car was the focus. Consumer tastes are powerful. The evidence about SUVs though is not good. A recent article I read on Apple News some 3 months ago painted a very ordinary picture on the SUV at all levels. In other words a sedan fight back was going to be very difficult but possible. The evidence, look at Tesla’s success with its Model 3, a sedan.

And when I reflect now, the more I feel that dealerships were failing, and will wither on the vine, though I say that with some sadness. The reality is that the software infrastructure of cars, starting with Tesla is the holy grail, the AI, the IP that sets up the servicing structure for cars in the future. And it is hard to do that well. look at VW and the herculean task for them to get their software right infrastructure for their first foray into mass production for its ID.3. It’s still in a messy cesspool.

The next great sedan will be a rival to Tesla, but we won’t see it anytime soon, even though GM only today on Apple News is saying it will. We need to get back to perhaps making a much better sedan, but let’s rename it saloon, or limousine with a cracking motor, whisper quiet, but with a dash like a Bentley. My dream cars in the garage are Rolls, Porsche, believe it or not, a Lotus Exige, a Toyota I road, a McLaren, and one I already have, the ZB Commodore, 4 cylinder, petrol turbo.
I can just continue to enjoy my ZB LT simply because it is a such a pleasure and thrill to drive every time, the goldilocks car that Holden didn’t know it had.
The final comment is about us. We should be driving on the other side of the road like most countries. Why bother accommodating Australia. Will the change occur

Tezza. I suspect when Gm sold Opel to PSA that Gm contracted to buy Insignia for Aus and North America.
There was probably little margin for Gmh and price of Insignia paid to PSA went up over the 2 and a bit years.
Gmh never really marketed it just sold it to fleets and rental car coys. I expected an ad blitz like when Commodore went to SIDI engines which they promoted as the biggest change in Commodore history.
All ZB got was a tiny bit of ‘modern day explorer’ at the start of sales in Au.
And the last VF s took ages to sell as well which I guess disrupted ZB s career. Dealers would push VF s in 2018 as the margins were better.

I never saw more than new 3 zb s maximum in the Gmh dealers near me.

As you say great car but lousy non exultant efforts to promote it.

2019 ZB Commodore RS 6Cyl AWD
On my RS (V6), in the Climate Control settings menu, there are two settings, "Auto Defog" and "Auto Rear Defog". If you set them to on, the climate control system will monitor for condensation and clear it automatically by 1. Turning on the AC if it is off 2. Directing the airflow to the window surface until it detects the condensation is gone.

Guys on here wuth the v6 saying they are wearing out in 8000-12000kms.
Not true. I drive aggressively and mine's done 29g (Continental Conticontact Sport) and they're about 60% (says the Holden dealer when it was serviced a month ago.

I can just continue to enjoy my ZB LT simply because it is a such a pleasure and thrill to drive every time, the goldilocks car that Holden didn’t know it had.
And that, is what I've been telling all my VF and earlier series friends. There is unfortunately a "Not Made Here" prejudice against the ZB. Most of it uninformed.

If you like the FWD handling, you will ABSOLUTELY love the AWD of the RS v6 and upwards. 68mph (110k in your units) recently in that storm weekend 4 weeks ago on the Hume to sydney, felt like driving 30mph in sunny weather. Zoomed past much more expensive sports cars crawling along at 30mph.
