I have a very early built GT4. Production date was June 15th 2015. Delivery was back in August 22nd 2015.
Are these early production GT4 affected? I have checked the Porsche link where you enter the VIN to check for recall. Did that and it shows no recall.
Canadian car with 6,800 KM

Very few GT4s built around that time (summer 2015) appear to be impacted by the third-gear failure found mostly in cars built after Jan. 2016.

When you mentioned very few failed, are there summer production like mine still failed?
Thanks for the info

I have heard of a couple of pre-2016 builds that failed but have no confirmation. Pretty sure they are mentioned earlier in this thread.

Thank you for answers. I have read entire thread but have a few questions.
1. Do we really believe that there is an isolated cluster of build dates that are affected?
2. Did the gear design change at any point. My understanding is that ALL GT4 3rd gears are the same?
3. There are reported failures in 718 Cayman, 981 Cayman and Maybe 981 Spyder
Sorry for asking similar questions nut Im just trying to be clear about this problem

It's pretty obvious that builds from March and April of 2016 have the highest failure rate.

Username - RocketGuy3
Date of manufacture - 5/2016
Total miles - ~4900 miles at time of failure
Number of track days - failed on 10th track day
Estimated track miles - ~750 miles
The failed gear - 3rd gear
Brief recount of the failure - Was accelerating out of a turn, engaged 3rd gear, and something felt weird (I would have to review video of exactly how it happened, memory is unclear since I was distracted by botching the turn with a car I'd just passed behind me). Engine just revved freely... no power.
Tires - Original Michelin PSC2s in the rear, had just replaced the original PSC2s up front
Other relevant info - Bone stock Cayman GT4 (had alignment done at dealer to max out negative camber possible from the factory, but that's it)
... I could post a video of when it happened if that's of any value to anyone.

Username - 981 GTS AUSTRALIA
Date of manufacture - 5/2016
Total miles - 65000 kilometres at time of failure
Number of track days - 0
Estimated track miles - 0
The failed gear - 3rd gear
Brief recount of the failure- Shifting upward, 1 - 2 - 3. Just felt as if in neutral. No crunching gears, no noise, no warning lights. Gear selected window displayed 3 and then quickly switches to 5 or 1. No other issues, just drives as if in neutral.
Tires- OEM Yokohama Advan
Other relevant info Drove to dealer. Within two days was told I'd be getting a new gearbox at no cost. Gearbox will be unopened and sent to Stuttgart.
