Any other users experience/fix these problems and how:

1- Driver side wiper blade is smooth until about 5 minutes of constant rain. Then it begins to chatter and skip both on the upswing and down... but only at the slow wiper speed, not the fast wiper speed. I have had them changed 2 times at dealership and thoroughly cleaned windshield with lighter fluid, clay bar, etc etc. If I spray the windshield with the washer jets while raining it smooths out for about 5 minutes then becomes skipping again.

2- Hot start issue is tricky. After driving for 15+ minutes when the engine is nice and hot (200 temp) I will park it (sunny day, cold garage, night time outside, doesn't matter where). If I attempt to start the engine again within 30min to 1.5 hours, randomly (about 20% of the time) it will stutter and shake for the first 8 seconds and then smooth out. If I try and give it gas nothing happens, I have to wait for it to smooth out. If I shut the car off and then immediatly restart it it is smooth as silk. I have had the tech run diagnostics and it isn't engine misfires as no codes are stored. There is a funny clunking noise that the tech identified as "heater valve opening closing on firewall" but checked it and said it was doing it's job. Cold starts are perfect. I have been through 10 different tanks of gas from different vendors as well as 2 Chevron Techron additives... no change. Always 93 octane. Spark plugs changed and distributer caps upgraded to new model. No change. Tech did find a loose grounding wire from the engine which he cleaned and tightened and the issue has been 50% of original description but still exists.

 

I got my '08 GT in March 2013. I didn't use the wipers for some time as I don't use the car on a daily basis. When I did recently, I noticed the driver side blade skipping quite a bit. Any one else having this problem and how did you fix it, if you were able to. The dealership recommended new wiper arms. Didn't fix the problem. Any suggestions anyone?

The first thing to try when the wipers judder is to clean the actual blade edge.
Baby wipes are perfect for this task and you may be surprised at how much black grime comes off.
Failing that, clean the screen with a good glass cleaner or even Vinegar. If you have any, try Gin, believe it or not, that's what they use on Submarine Periscope lenses.

Baby wipes are also the best thing I have ever found for removing insects from the screen too!

So Les,
How do you know about periscopes??? Are you a retired or serving Submariner ???

They are very good at getting some people into countries unseen Frank!
For the record, I am officially retired. Well, mostly.
I did know my way around a Sub' though.
I'll let you work the rest out for yourself.

I now know
I would have been there with you one way or another

 

Les,

Thanks. My Bentley dealer said they have been having trouble with blade arms not flexing back and forth. I think they got it fixed. But I'll try gin on the glass. I have used vinegar and it works great but gin may be better.

Hi Sunnyside.
I was doing stuff during the troubles.
That will give you a time frame.
Happy days matey!

To clean the wiper blades in use 303 Protectant. Seems to make them last longer too.

 

I bet your vacuum hoses have a hair line crack in them. do you hear a pump running when you hit the brakes?
