2023 Giant Reign E+ flashing L2 led

[martin_m_bo]

i think the problem is the giant software....like someone said before. giant thinks they coud do better then yamaha and from the start this giant software sucks. if i coud and if it is possible i woud go for yamaha software but i dont think it is possible. if someone knows how let me know

So after 4 months going back and forth with giant, they tell me the motor has no problem, determine that I ride in the smallest cog on the highest power assistance, pedal too slowly... Utter BS and it is my fault, then i am told the bikes have humidity problems and i shouldn't ride in the rain and should dry my connectors mid ride...
I then ask should you spend 6K on a bike then put bathroom sealant everywhere to protect it from water??? especially i bought an offroad bike. I had to tell them Ive been dirt biking for years even on E dirt bikes river crossing and i've never heard such rubbish
They literally have no solution and are pushing it back on the customer. Weird thing is i cycle up hill it cuts and goes red.
I stop to chat with a mate it goes red. I ride dh trails it goes red. I ride in dry weather or wet weather it goes red.

They will lend me a battery to see if my battery may be the problem...

So I'm not sure they have a solution, at least not in my store. and may have spent too much on replacing motors and are cutting costs.

PS yes I've cleaned connectors tried the die electric grease, but it doesn't change the fact that it cuts out even in dry weather.


bad luck with giant customer service...

How old is the bike? Is it still under warranty?
If the motor is bad and it's under warranty it needs to be replaced by giant.
If it's due to you riding in the smallest gear uphill with maximum power it still should be replaced under warranty and they should advise you to change your habits with the new motor.
Either way it still should be replaced under warranty.
What country / state do you reside?

I gotta say, I was in the market for a new bike and came real close to pulling the trigger on a reign e. After reading through this thread I've changed my mind. Looks like the Giant warranty response is a real lottery.

The bike has 1500 km and has 6 months warranty left ( so it is just under 2 years old.
Good question I am dealing with Giant in France.

The bike is used to climb up roads and alpine tracks and ride town enduro tracks.
I agree it should be replaced but they are just rejecting it so i'm most likely going to take it to a consumer association and lawyer. As the bike is now unusable more than 40 to 60mins. In the past i could ride 50 km 2000 m vert, no issues. and to get that range you have to spin and keep a good cadence up use small gears and low assistance.

NicoMTB I totally feel your pain! I was the first one to have this exact problem over a year ago. After a motor replacement and no change I was told the same thing , yet my buddies bikes when I rode them on the exact same runs the same way they had no cut out. Giant said it was my fault as well. After mentioning I was going to take legal against Giant I was quickly offered a full refund, which I took and never looked back. I now have a Yamaha Moro with the exact same x-3 motor but tuned by Yamaha in a Yamaha frame and I have had ZERO problems with anything let alone the motor cutting out. It seems Giant in their wizdumb have screwed over an absolutely excellent motor with their own programming. It's too bad it makes the Yamaha motor look bad when it's not. Good luck with your dilemma, perhaps try mentioning legal action and see what happens.

I'm in Texas, our regional Giant representative hinted that it was a seldom occurring known issue. From the time the bike shop hooked my bike up to the computer and read the information they immediately acknowledge the motor was bad and one week later I picked up my bike with a new motor installed.
Of course we are in Texas, it's possible the local giant rep didn't want to be hung from a noose for failure to oblige

Ha ha ha nice in France we ve gone soft no more guillotine..
So after filming the issues and all their recommendations still failing the Motor is replaced and battery as well.
Bike has been in warranty for 5 months. Just head aches...
I'am selling it after. And already have something else arriving soon.
Customer service and the way it was handled it was just a disaster.
Maybe badluck. As when it works the frame geometry Mx set up is spot on.

Hello, I'm experiencing the same issue. It happened to me 15 times during my last ride this weekend (with the latest update, the one that requires creating an account, etc.).
I contacted my dealer who is very nice and involved. He advised me to use dielectric silicone grease (Velox brand) and has submitted my issue to Giant.

Of course, I will come back and share anything that might help resolve the issue.

Did the dealer specify where to apply the grease? Searched for Velox grease and it seems to be not be available here in the U.S. . I wonder what the differences are from other dielectric grease?

 

[blbl]

@parkp81 Yes, you need to apply the grease on the battery and bike contacts (a thin layer is enough). I will do it this weekend and post a photo of the grease application.

Regarding the brand, he told me he uses this one (Velox) and it works well for him, but I imagine any dielectric grease (for electrical contacts) will do the job.

dielectric grease is an insulator it is non condusive and waterproof , if you put it on the connectors you ll block the current. velox is a special contact grease that does transmit current.

 

[blbl]

@NicoMTB no it does not transmit current,

Dielectric grease is used on electrical contacts to protect them from moisture, corrosion, and contaminants. It prevents connection problems by insulating the external environment while allowing good direct metal-to-metal contact.

When connecting the two parts, the connection pressure pushes the grease out of the direct contact points, allowing good electrical contact while sealing the areas around the contacts.

This is probably not the cause of the issue we're experiencing here (LED L2 flashing red), but we need to eliminate any doubts.

Ok , thanks.

I have used a thin layer of Super Lube dielectric grease on the plugs to the motor and battery contacts. I have cleaned the battery contact points with electrical cleaner and have not had issues since. Hopefully it helps you, like it did for me.

Hello,

Just like parkp81, I cleaned the battery and bike contacts with a contact cleaner spray and applied dielectric grease (see photo). I also tightened the battery mount completely to ensure there was no play.

I turned the bike ON and without even moving, it went into error mode 20 seconds after powering on. To be sure, I slightly loosened the battery mount since my colleague’s (who has no issues, Reign 2022) was less tight and did not have this problem at all.

We went for a ride, and the problem occurred more than ten times, then after 10 km, it calmed down.
We took a break for 5-10 minutes, the bike turned off automatically. I restarted it, went up a technical climb, and it crashed in the climb (~2 minutes after I restated), but not at all for the remaining 15 km. I feel like it only crashes when it’s cold.

My dealer and I are wondering if it’s the battery. I will swap it with my colleague’s (if it fits) to see what happens and get back to you.

 

[dimitrin]

They need to hook it up to the Giant dongle and read the report it generates on the PC.
Until then, they are playing the guessing/ wishing game while your riding with a unreliable bike.
Giant knows of this issue, the shop needs to put pressure on Giant for a solution.

I forgot to mention that I also cleaned the battery contacts with the electrical cleaner and let it dry completely before installing it back onto the bike. For dielectric grease I used a very light coat using a qtip to apply it to the battery pins you show in your pic.
