just had an issue with my liftgate today... only 1400 miles.. never had an issue with it before but now my liftgate wouldn't close... not even manually... i tried gently pushing it down but it won't... it just goes 3/4 of the way and something seems to be stuck. bringing it to the dealer on sat but just wanted to see if you guys had any thoughts on this.
 
thanks.

The motor is torque-sensing.
When it encounters resistance, it goes backwards.
Clean the struts. If no help, bring it to the dealer.

#14 of 21 Jam safe feture on auto lift gate? by danny05

Oct 17, 2010 (5:54 am)

Hi,
My 2010 Mazda CX-9 has an auto open/close power liftgate. The manual says it has a jam safe feature that keeps it from closing if it hits into something, and causes it to open again. I tested it out after it almost closed on my son and could not stop it from closing. Does the CX-9 have this feature and mine is just not working, or is this something that has to be added or programmed? Thanks in advance for any insights!

As I said above, it is torque-sensing, not remore-sensing by ultrasound or anything like that. It actually will hit something (a person, maybe) and reverse if the reverse torque is big enough. Kind of like the elevator doors.

Hi all,
 
Same problem here, 2010 CX9, 8 months old. Taking it to the dealer next week, as my wife and I were in a parking lot after a shopping trip this past weekend opening and closing the thing probably 10 times, like two fools, only to have it keep not latching and doing the 3 beeps. Finally we gave it a gentle push and it latched. Our salesman had said NEVER EVER push it, so we were hesitant, but it clearly was not going to latch on its own.
 
Meanwhile yesterday we used it again and it latched on the first try. Either way this has been an intermittent recurring problem, so I hope it's something they can fix.

I have to correct myself (what I posted above).
The PLG is both torque-sensing and presseure-sensing.
Torque-sensing is easy to understand. Once it encounters resistance, the motor reverses itself. The pressure-sensing is based on the two pressure strips on both edges of the PLG. Put a little pressure on them, the PLG reverses itself.
 
For drc1017,
The latch is not properly aligned. Dealer should be able to fix it if they can reproduce it (says in a extremely cold day or hot day). If not, find a better dealer.

#19 of 21 Mazda CX-9 power lift metal failure by margiemc333

I've had my 2008 CX-9 for four years, and the mount for the hatch back power lift ripped out of the sheet metal of the hatch. I use the power lift several times each day and the sheet metal seems to have fatigued and given out. We purchased an extended warranty from the dealership (when we bought the car), and it's with First Extended Service Corp. We were told that it covered everything that the original warranty covered, but are now being told this problem is not covered. Mazda estimates $2-3k for this repair!
 
Anyone else with this problem, and how did you resolve it?

FYI: Mazda decided to replace the hatchback for free!
