PDR quality
 

Welcome to Chevy, the quality on your $145K Chevy may or may not be worse than on your $90K Chevy, which may or may not be worse than a $20K Chevy. It seems these cars are a gamble, each one having their own unique issues. Back in the old days, I'm told these unique issues were called "features" or "added personality", but today they are a product of poor quality control.

GM supposedly issued a TSB back in 2016 for the PDR video quality. That was for Corvettes built before mid- March 2015. GM issued a reflash for the software and it was told they upgraded the PDR systems to eliminate the very problems described. I only have 300 miles on my ZR1 since late August 2018 before the cold weather set in so I haven't recorded and reviewed much video yet. I will take note of this when spring arrives.

Make sure the camera lenses are clean.

I've had good quality with my recordings. It's possible that the SD card is too slow. I'm not sure, but there are different speed ratings for read/write on SD cards. That could possibly affect it.

I had the same issue with my ZR1 and it was far worse than my 2017 or 2015 Z06. I haven't tried my 2019 GS PDR yet. The 2016 fix was to correct the green tint issue. I wrote a very detailed description for the dealer which went to GM and then to Cosworth. I had a Cosworth engineer reach out to me to upload a file for analysis but I never got any solution and he never replied to follow-up mails. Please go to your dealer and have them file the issue with GM so we can get some momentum to fix it. You can see it in any of the track videos on my YT channel.

Glad to hear they fixed yours but kind of pissed off they never offered to replace mine. I sure hope I don't have any issues with the GS.

Finally got a chance to take the car to the dealer so they can address the horrible PDR video quality.........I will update thread when I get some feedback from the dealer.

Maybe its fhe data card your using. You might try a different one before having the dealer dig into the car.

. 10 inside C speed card?

It isn't the video card. Choose the wrong card and you get nothing. People are getting poor video quality Vs nothing at all. The source data from the camera isn't correct.

My 2019 GS has the same issue my ZR1 did and is going to the dealer tomorrow. I am told there is a new camera design that they were going to put in my ZR1 before I totaled it. Now I need to start the process over with my GS.

I’m guessing that is what GM “tested” in my car... the replacement camera was not handled in the “normal” fashion (at least that is what my dealer service tech told me). The replacement unit came directly from the GM engineer that contacted me last September... and it arrived with specific instructions to return the “old” camera directly back to the engineer’s office (not normal).

Whatever they installed, it fixed the issue. My PDR picture quality is now as good (or better) than what I experienced in my 2017 Z06. Before the replacement my ZR1 picture quality was the same or worse than what I saw on your PDR videos you posted.



Neither my dealer technician (or I) ever heard anything back... no indication what if anything they found wrong with my original PDR camera... nothing at all.

How could we quantify the quality of these PDR recordings? Could you read a license plate for example on a car front of you? I did notice 'blotchiness' on Poor-sha's recordings (on his ZR1) that I didn't see on his Z06 videos.

It is really a shame that GM couldn't spring for 1080 on its gear. Penny wise in my opinion. Especially on a $150K car.
