I bought a DJI Mavic Mini at the beginning of March, and one month after owning it the drone had a sensor error that caused it to take off on it's own, resulting in a crash that broke the gimbal in the drone. The drone took off uncontrollably and it was not responding to the signals from my RC. This resulted in the drone crashing and breaking. I sent my drone to DJI, and after they inspected it, they said I have to pay because it is not covered under warranty. I will paste the email I received from the support rep, where they refer to two different instances to support their diagnosis; one in March 13th, and the other in April 10th. From reading the email, it seems like they are trying to suggest that the issue that happened on April 10th is correlated to the issue on March 13th. I don't see how the two instances are related, because since the March 13th incident I had several succesful flights without any issues at all. Even on April 10th I completed flights without issue. Furthermore, when I go to look at my case status, I have an invoice asking me to pay the DJI Care Refresh replacement fee, and the only supporting evidence that for their case analysis diagnosis is a screenshot of my preflight that clearly shows everything is "Normal". I will attach that picture here.
Here is the email
"Incident date: 2020-04-10
Incident time: 498 seconds
FLY051
1. The aircraft worked under Tripod mode, and responded to the pilot’s command well with a strong satellite signal.
2. Flight Time T=498s, Relative Height H=3.8m, Distance to Home Point D=30.2m, the aircraft struck an object and fell. Pilot commanded yaw right, roll right, throttle down and pitch down prior to impact.
3. The incident coordinate: 49.286864 -123.11494996
(PREVIOUS INCIDENT)
Incident date: 2020-03-13
Incident time: 718 seconds
FLY040
1. The aircraft worked under Sport mode, and responded to the pilot’s command well.
2. Flight Time T=718s, Relative Height H=0.4m, Distance to Home Point D=27.4m, the aircraft struck an object and fell. Pilot commanded pitch back and roll right prior to impact.
3. The incident coordinate: 49.318927 -123.056883
4. The aircraft could not avoid obstacles, user did not allow enough time for the unit to brake before impact.
According to the analysis, the incident was not caused by any product malfunction.
We can still proceed with the repair, however, you will cover the repair charges."
It seems like DJI is suggesting that the incident on April 10th was due to user error. How is it that you are failing to recognize the "sensor error" message that I received ? Why is this not included in your analysis/diagnosis? Of course I was moving the throttle when my drone took off uncontrollaby, I was trying to avoid it from crashing or hitting another human being... luckily it hit a wall before the damage was worse than a broken drone.
This leaves a very bitter feeling in me, I really feel like I cannot trust this company which is a shame because I was looking to upgrade to some of their professional drones later in the future.... not if they try to disguise workmanship defects as an operator error. Has anyone else encountered this? What did you do? How can I escalate this issue and get it further revised?
Using my DJI Care Refresh replacement only one month into the ownership, due to a sensor error, doesn't sit well with me.
