Distorted Defective Windshields on W221's

Hello all,

I test drove a couple W221 S550s and I noticed that one of them has a weird distorted windshield.

When you are in the driver seat looking straight ahead, you will notice a very slight distorted image. Its almost like the glass is crooked....but when you inspect the windshield, it looks perfectly fine. Its like wearing glasses out of focus..

I told the sales guy but he said nothing is wrong and he couldnt see anything distorted. He said that it might be the design of the car to "deflect" sunlight...but I call BS...

I was wondering if anyone with W221s have had the same problems with their windshield glass.

Saw the same issue when test driving one last weekend. I have also seen this in some American cars. For an American car I suppose a defective windshield is par for the course, but on a Benz?!?!? Very strange.

I do not believe it has anything to do with deflection or glare reduction, I believe they had to shape the glass to fit the shape of the winshield frame. It appears that there is a slight "bend" in the glass.

The salesperson tried to tell me it was the infra-red glass, but I have a GL450 with that feature and see no such distortion.

I have not noticed this on my car (it has the IR reflecting windshield). Is it something really minor that you do no notice if not specifically looking at?

Well I see the distortion looking straight ahead eye level, so yeah you couldnt miss it. I got dizzy after the test drive, it was like "wearing glasses with the wrong perscription"

I did some googling and found that some other car manufacturers had this defect, but found nothing on a benz.

I bet the VW Phaeton/bentley flying spur was on that list. They had a terrible problem with this.

Driving my fourth new-gen CL and had S550 at its launch...never noticed a problem w/windshield of any of my copies...in fact, have been impressed by how well these windshields sustain impacts from rock chips, etc w/minimal damage....

Given how many OCD S-Class owners are on this Board would think more would have noticed/commented if these defects are indeed a prevalent issue....

Suspect any complex, high-tech glass has some finite defect rate......from what I understand, what makes new cars w/windshield defects essentially lemons is that it's impossible to replicate the robotic installation of a windshield in any post-factory replacement...sort of like how any paintwork/nanotech clearcoat work in any post-factory setting cannot duplicate the quality/precision of factory automation/robotics/advcd mfg tech....
