He knew about the brake problems AND also about the dashboard reflections !!!!!!
I spoke to the salesman as I wanted to sit in a MK4 to see if it hurts my leg the way my MK3 does.
It doesnt so I may have to get one
The question I have is to confirm the uplift does not have the brake problem and also the dashboard refelections are less on the MK4

Hi,
The brake issues have been resolved. As far as I know, some cars have been recalled under warranty to fix the problem, and I don't think there are any other issues.
I don't understand what you mean when you mention reflections on the dashboard? I've never had any particular problems, but I did put a dashboard cover (purchased online) on it so as not to damage the plastic if I put something on it, and I haven't had any problems.
-
Some people notice it and others dont. Its never been explained why.
I hope the mk4 is better but I wont throw out my felt tiles
-
On sunny days I do notice dashboard reflections on the windscreen of my Crosstar. A matte black felt dashboard cover helps to reduce the reflections to an acceptable level. Another trick is to wear polarized sunglasses, they eliminate the reflections completely.
-
There are some matt black dash cleaners that help reduce the glare. I found the one sold in Tesco to work best
There is a thread here somewhere comparing the likes of Tesco and Sonax and others

I've got the Advance Sport and I'm pretty certain the brake problem doesn't apply to the refresh models. I don't think it even applied to all the early ones, there were some bad batches of parts and if your car didn't have one of them it would be ok.

I find polarized sunglasses very effective. Both for any dashboard / windscreen glare and general brightness and reflections in the distance. (Which would happen in any car. )
They are available as prescription lenses if necessary.
I had thought about also adding a dashtop mat or using matt cockpit spray but no longert found it necessary .
Polarized lenses have a reputation of sometimes producing a banding effect with some auto glass. The Mk4 Jazz windscreen is completely free of any banding. There is very slight banding on the side windows and rear screen but you really need to concentrate and focus on them to notice . It doesnt affect visibility.
Ideally I should get a CPL (circular polarizing filter) for my dashcam but havnt got round to it yet :-[
-
The banding / bubble effect seen on some glass whilst wearing polarised sunglasses is only sometimes visible when looking through toughened glass. The windscreens on modern cars are made from laminated glass so they should appear clear at all times.

Circular polarizing sunglasses would be a good idea as well!
I've had (linear) polarizing sunglasses that completely filtered out the screens on some of a certain german (and it shall remain unnamed) car manufacturer :D (just let me tell you this: They truly excell at shovelling their own grave!)
Honda - at least by my humble experience - doesn't suffer from this issue (or the two pound polarizing sunglasses from Lidl are even far better than expected)!
-
A quick test in the showroom revealed that I would suffer the reflection problem in the Mk 4. I reckon it's a combination of of eyeball position and windscreen angle and it troubled me in both the Mk 2 and Mk 3. Polarised specs are one option but are inconvenient when frequently changing between sun and shade. I therefore bought one of these https://www.amazon.co.uk/dp/B0CWV9SMNB which went into the Mk 4 once I had taken delivery. That one is out of stock but I expect someone else sells the same thin. At £16.99 it was money well spent.
-
That's exactly it.
I wrote dashboard protection. With that protection, I don't mark the plastic when I put something down, and I don't get any glare.
-
I'd like to remind you of the passenger side airbag issue, though: https://clubjazz.org/forum/index.php?topic=11708.90
My opinion stands: Everything you place on the (passenger side) dashboard might eventually land straight in your face!
(propelled with explosive force to boot!)
The Jazz has so many spots to deposit stuff safely - why would you want to jeopardize your and your passengers security by placing stuff upon the airbag blow area?
-
If you are driving blind unless you put something on the dashboard then whats the lesser of two evils

You might consider to only cover the driver's side (where there's no airbag underneath the dash).
(don't tell me you are "blinded" by dashboard reflection of the passenger side!)
-
If you look through the passenger side of the windshield, which is sometimes recommendable in traffic, the reflection is just as bad as in driver's side.

Possibly - I'd like to remind you of how often you're looking straight forward and how often sideways while driving.
Plus: Mere physics tells us that the angle of entry equals the angle of exit, so the light source would have to be coming straight from your passenger side in order to "blind" you.
-
What winds me up is that no car maker has fixed it or no research has been done to find out how only some drivers are effected by it.
If you put a sticker in the wrong place of your windscreen it could be result in a MOT failure but if I was driving with sunlight in the wrong angle I would not see where I was going.
Before you ask I have regular eye tests
Im hoping that not only will buying a Mk 4 stop and prevent more leg problems but also do away with the felt tiles I have to put on the dashboard
-

As mentioned before: It is pure physics! - It probably only affects people of a certain hight range (remember: entry angle equals exit angle).
Regarding the manufacturers: Their foremost concern is, that it has to be cheap!
-
If you are driving blind unless you put something on the dashboard....
Driving blind...?
In sunny weather and with certain lighting conditions, you indeed can see the reflection of the dashboard in the windscreen, but blinding?
And yes, I know that the effect isn't the same for everyone (fortunately, I have hardly any trouble with it).
But... I realised that the more you look AT the windscreen instead of THROUGH it, the better you see that reflection.
As a test, try focusing on an object at a distance of some 30 to 40 meters. Don't concentrate on the reflection that is still there, of course. Does it still obstruct your view?
A welcome side effect: looking (far) ahead is important, as my driving instructor taught me 60 years ago!
-

The basic shape of the Jazz has a large windscreen with a flatter slope than most vehicles so the reflections go into the cabin rather than to the roof. Honda could fix this in the factory by fitting a non-reflective dashboard surface designed to address any safety concerns.
FWIW, I sit fairly upright so that I'm seeing the road through the upper part of my varifocal lenses. Those who like a lower driving position may be below the line of the reflections.
-
Cars with steeply raked windscreens suffer more from reflections. The height of a drivers eyes, whether due to their height, sitting posture, seat height etc can alter how much it affects them personally.
I used to get a lot of reflection with an Opel Corsa. I spent a lot of time looking round fabric shops etc for some sort of fabric, felt, tiles etc that would not reflect light .Stuff that looked quite promising was still surprisingly reflective.Fortunately I never bought any as even a metre of fabric would have been quite expensive. The best solution I found was a black bath towel. There may have been special non reflective fabrics for photographers but I never went that far.
It is a shame on vulnerable cars the manufacturers dont make more effort avoid traditional shiny plastic trim and find some sort of non reflective alternative. If such a finish exists it would probably gather dust and dirt quite quickly.

Going back to the original question is it better on the MK4.
-
The reflections on a mk 4 Jazz are less of a problem than on the 2010 Corsa , partly because the jazz dashtop is relatively featureless. The Corsa had fancy styling mouldings which show more.
But I agree with Jazzik. If, you focus on things happening beyond any reflection rather than on the reflection itself your brain subconciously starts to disregard the reflection and you notice it less.
-
...and you notice it less.
...but you see more... :o

A bit like eye floaters. Once you see one, it follows your eye for hours.. you have to focus past it to stop seeing it. :o
-
But if you cant see anything past it how can you focus on something ahead

More like opening the net curtains
-

I think the answer is yes because it's flat so you get (or don't get, depending on eyeball position) a uniform reflection which is easier to look through.
-
Can't be net curtains(https://www.cheesebuerger.de/images/midi/konfus/c086.gif), if you write:

I dont find any image reflection ,which only occur in certain lighting conditions, actually stops me seeing properly. You can concentrate through it . Its a bit like having a head-up display as found on aircraft and a few recent luxury cars. With this you learn to either focus on the speed data etc projected onto the windscreen, or on the view beyond , or a bit of both. But of course the Jazz does not project any data so its easier to ignore it completely.(a missed opportunity there Honda ;D )
General bright reflected glare off interior plastic is a separate problem and present to some extent in most cars . The mk 4 maybe a bit worse than some. And bright reflections and glare from distant objects happens in any car. Thats why i always have polarized sunglasses in the car, summer and winter . I often dont need to wear them . I may take them off if the sun goes behind a cloud, but can usually leave them on for temporary shade , or a well lit tunnel. Your eyes can take a few seconds to adjust to a sudden major change in light intensity anyway even without wearing sunglasses.

I've got a pair of clip-on, flip-up polarised specs. The challenge is to remember to put them on before I start driving as clipping them to my varifocals can't be done on the move.
-
now you guys have me wanting to buy polarized sunglasses :) I used to need glasses in the car since I was about 25 (nearsighted). So then I could not wear regular sunglasses. But as I am getting older now I do not need glasses for distant objects (nearsighted). My eyes somehow removed this problem. My father had the same thing. But now I am farsighted and need glasses for reading.
So after this discussion I looked for some fancy "pilot sunglasses" my brother gave me in the 90-ties (since he did not like them) but they are not polarizing. I might buy some polarized sunglasses soon.
-
I keep a pair of polarised clip-ons in the car and use them almost all the time. Maybe that's why I haven't been bothered by screen reflections. Even when the sun isn't particularly bright, there's a lot of glare off the road and they reduce eyestrain significantly. With a bit of practice, they can even be put on and removed one-handed!
-
….and with clip-on flip-ups you can simply flip them up when entering a dark area. There’s no need to take them off, in or out of the car.
-
Make sure they are genuinely polarized. I once bought some flip ups that claimed to be polarised but were not. Its amazing the difference polarized lenses can make in other situations. Looking in a lake ,river etc you see the fish so much better ;D

yeah I am looking at established brands like Serengeti, Revo with real glass polarized lenses. Not cheap :o ... luckily the post is still on strike here in Belgium. About 1 month now, every year the same. Still waiting for a package that was sent to me on April-8th. So I am ordering nothing at the moment.

Yesterday I got into the car in really bright afternoon sunlight and the reflections were quite bad, not undriveable but really noticeable in those particular super sun conditions all across the screen. My specs had a special offer for polarised prescription sunglasses at the time. I put them on and all reflections magically disappeared... a wonderfully clear view.
Unfortunately without super expensive non reflective windscreen glass the fuel saving aerodynamic shape of modern slanted windscreens will always have this drawback.
