The GPS failed on my P4P and DJI repaired/replaced it under warranty. I used the new P4P for ~ 10 flights... The last flight I did, the drone started spinning out of control... flew horizontally another 20-30ft, then more spinning before falling to the ground. The P4P wa sent back to DJI in California and I was sent a service quotation:

As the P4P was only about 6 weeks old with only 10 short flights I expected DJI would accept responsibility that the P4P had a malfunction (props were attached correctly and the P4P did not hit any object causing it to fall). I did have a motor idling / possible loose prop message on the second spin so I can only guess that one of the motors failed.

The case was disputed with DJI but they stand by their opinion that the drone is either not covered under warranty or not caused by a malfunction. I guess this is mostly my opinion, but I expect better support from DJI... A $1,500 P4P should not last for only 6 weeks / 10 flights!

Hi. I am sorry to know what happened to your DJI Phantom 4 Pro. Can you please provide me the case number for me to check and help you further.

Hi coloradophantom, thanks for getting back to us. Upon checking your case number, the drone was activated around 2017-07-03 and we're sorry that it data analysis will not be offered if the unit has been out of warranty period. You may find this in our policy: https://www.dji.com/service/policy

As you mentioned the unit was only 6 weeks, may I know where did you purchase it? Could you offer the purchase invoice and aircraft SN for double check? We'd like to check the exact status, thanks so much!

The Phantom 4 Pro with Serial No 0AX2F6R0020021 was shipped to me on July 10, 2018; therefore, it was not activated in 2017!

I managed to get the previous case number and sorry to tell you that the warranty will inherit the previous warranty period, instead of extending. Hope for your understanding.

You replaced my original P4P with a malfunctioning P4P and now I have to pay... Looks like I have to consider my legal options for getting this situation resolved.

On the repair list it has the camera main board being replaced for $144. Based on my inspection it was not damaged in the crash. Can I get proof from someone at DJI on the main board being damaged.
