Just amazing. I had the same problem and the negative terminal disconnect/reconnect fixed it! Mechanic wanted to keep the car for a few days so he could trace wiring and find the issue; got lucky that I saw this post first.
this worked for me as well!Before taking it to the dealer do this. Remove the negative battery terminal and wait a few minutes then put back and tighten. Try the hatch.
That's the hatch reset.
Fixed mine and somebody else's on this forum
The CX-5 like many new modern cars WILL act up if the battery is below spec. Same thing on my Mazda 6. The ECU, AC, lights, sound system, navigation, BSM, throttle electronic wiring, interior lights, city braking, all sorts of electronics ect, ect all require "Clean" power.But the vehicle continued to start and run ok, and it was only the liftgate that wasn't working? And was it a battery testing tool at a shop or parts store that showed the battery being 'dead'?
Not always. Some people might have connected a parallelly battery before the bad one was removed. In that case, the liftgate did not get a chance to be reset/rebooted.You do realize that the battery was disconnected for a few minutes as the new one was installed...
Just a note that on late model corvettes, 1998-2014 and probably later years, reserve capacity of the battery is much more important than cranking amps. this is due to current drain while the car is sitting, as most of these do as a weekend and good weather drivers. It is actually somewhat difficult to obtain a battery with the reserve capacity recommended. If it sits for three weeks, it’s a chance it won’t start. And I can tell you from experience a low battery voltage causes many issues on these cars.Not always. Some people might have connected a parallelly battery before the bad one was removed.

(No need to go thru re-initialization process ... windows, radio stations, etc.)
It seems that the liftgate only works when voltage is higher. Starter (and others) might continue to work as long as the electric current is large enough (cranking amp).
I had the power lift gate problem this weekend on my 2018 CX-5. I tried pulling the PLG fuse, but that didn’t solve the problem.Here are the fuses you will need to recycle.
I'm not sure if your 2018 has a PLG Control Module. If it does, then there will be a 20A PLG fuse in the ER fuse box. If there's no PLG fuse, then your vehicle doesn't have that module.
For the RBCM, there are 2 fuses protecting it: the 15A ROOM fuse in the ER fuse box; and the 25A D.LOCK fuse in the cabin fuse box.
Thanks for posting your result, and it's good to have confirmation that it works just as well as the battery disconnect.I had the power lift gate problem this weekend on my 2018 CX-5. I tried pulling the PLG fuse, but that didn’t solve the problem.
While doing further research, I came across this thread.
I pulled the ROOM and D.LOCK fuses for 60 seconds and replaced. Now the lift gate works.
Wanted to note this fix works and say thanks.
I’m glad it worked.Thanks for posting your result, and it's good to have confirmation that it works just as well as the battery disconnect.
Yeah.. great that it worked.. the Mazda dealership actually disconnected the battery to get my liftgate reset. Surprised they don't know that trickI’m glad it worked.
It stuck me that pulling fuses is probably a lot safer for the casual owner, compared to fussing with the battery.
Had the same problem. Body shop fixed car but liftgate didn't work. Troed to reset by holding the liftgate button but that didn't work. sometimes gotta disconnect the battery. Problem is disconnect battery might reset other stuff.The lift gate on our 2019 CX-5 is stuck! I tried all of the electrical fixes and nothing. I tried the mechanical release inside the tailgate and it still won't open. I'm stuck!! Help!!
I have tried all of the electrical possibilities. I have tried the manual method to unlock the latch but that hasn’t worked. The gate seems like it is stuck.Had the same problem.

The body shop disconnect and reconnect the battery to get it to work. I'm not most knowledgeable. So check to see how to best disconnect battery without messing something else up.
Hmmm. The mech said they disconnected for a few minutes and reconnected to fix it. Wonder how good your battery is. Can you test your battery? I know it's only couple years old but it's possible if not enough juice then maybe it's not getting enough juice to open.I have tried all of the electrical possibilities. I have tried the manual method to unlock the latch but that hasn’t worked. The gate seems like it is stuck.
If the manual method doesn't work, that would seem like the latch mechanism is jammed, so is it possible that some object was trapped in the gate the last time it was closed? There was a thread a while back posted by someone who had a backpack strap jam up the latch, and who was fortunately able to work it free enough for the gate to open.I have tried all of the electrical possibilities.

I can’t see anything. I am going to try fixing it later. It was just too hot yesterday to spend too much time in that car.If the manual method doesn't work, that would seem like the latch mechanism is jammed, so is it possible that some object was trapped in the gate the last time it was closed?
