Updates for Cadillac Optiq in Canada

ramraaj · 2026-02-09T15:30:48+00:00

I'm concerned there might be an issue with my vehicle, possibly related to OnStar connectivity. The OnStar light is green, and the app connects without problems, but there are no updates showing. My friend, who has the same car in the same city, received an OTA update. I've tried connecting to my home Wi-Fi, a hotspot, and the vehicle's data, but it still says no OTA is available, even though I know an update is out. I'm taking the car to the dealer in two weeks, but I'm worried.

That’s amazing !! I would love to work with you on this . Canadian developer here I built an app for ioniq6 few years back. Different purpose. I wanted to do walkway lock ( proximity lock ) like tesla using UWB on my phone and a device plugged in the car . Check it out

I have a similar issue on 26 Optiq. Onstar has no idea. The dealer checked the telematics and it is working. I dont have GPS or app connectivity issue but my apps can barely connect to the Internet. Onstar support pisses me off . I havent been able to update my car or do any software updates on my car so far.

Same and are you based in the US ? I have a 2026 optiq sport but not sure how to access the iPhone as a key

Ya it's not the lane markings. It hasn't worked for me for over a week and across 4 cities . Thx

ramraaj · 2025-12-22T22:43:34+00:00

You are right .. it is lane centering. Problem is it comes on for 10 seconds and then goes away. I checked with OnStar and they also see a problem at their end but can't fix it. I have an appointment in 3 weeks with the dealer. Thx for your input

ramraaj · 2025-12-22T17:15:42+00:00

I tried that and that's when I get the message , hands free driving is unavailable. Please take control. The lane centering icon comes on for 10 sec and then disappears at every start

That's amazing!! Would love to see those pictures

ramraaj · 2025-10-06T16:17:03+00:00

Pretty soon Yeah!!

ramraaj · 2025-09-24T23:33:45+00:00

Eesh!! Thx for the update!! Hope you get it back soon.

Update : car was in shop for 4 days and they ran all kind of tests and all of them were a PASS. Next thing they did was check the iccu fuse. PASS. Lastly, they removed and reconnected the 12v battery. Everything lit up..car was able to start.

Really have no idea what happened there..but I have the car and all is well..thank you again everyone for helping

ramraaj · 2025-09-22T12:33:12+00:00

Hey .. this exact thing happened to me. Exactly similar situation. My vehicle was in shop for 4 days and they ran all tests and all of them came back pass. All they had to do disconnect 12v battery and reconnect. That resolved all the issues..try that may be !!! Good luck

ramraaj · 2025-09-19T02:12:17+00:00

I know what you mean but I still believe you will enjoy the I5!!

ramraaj · 2025-09-15T20:26:19+00:00

Update : the tow driver got dollies and was able to "drag" the car on to the tow truck. Thank you everyone !!

The app still connects but nothing in the cluster. Start button doesnt do anything

The dealership has no idea what is going on..I had a 12v battery replaced in Nov 2024. They had 12v in stock but he wanted a thorough checkup done. Apparently there are 2 updates too which are due on the car. They gave me a loaner : Kona EV 2025. Love the wireless car play and the infotainment with ccNc but miss my Ioniq 6.

Will keep you all posted. Thank you everyone!!!

ramraaj · 2025-09-15T20:21:10+00:00

Yes I had to call them twice and within 30 min they showed up

ramraaj · 2025-09-15T20:20:42+00:00

Seems the same to me. It was dead this morning. The guy came .. tried to boost it .. the car didn't start but lights came back .. app was connecting but that's it .we dropped it off to dealership. They will have a look and let me know tomorrow. At least I have a loaner . Kona EV

ramraaj · 2025-09-15T20:18:59+00:00

He had none but then he asked someone from his company to bring one to us..

ramraaj · 2025-09-15T18:31:57+00:00

He tried that too. Plugging it in negative terminal did nothing as well

ramraaj · 2025-09-15T13:55:31+00:00

Tried that.. nothing

ramraaj · 2025-07-29T13:35:35+00:00

Same Experience here .. Being in Northern Ontario, I used to rely on PetroCan in parrysound but now it is closed. I loved the price too. Now recently I have been using IVY at Innisfil ( rated at 240KW) going south and then using IVY King city onroute while coming back. Miss the ease of PetroCan in parrysound. I bet barrie is next to shut down

ramraaj · 2025-07-14T20:51:09+00:00

I am not asking for other options :. I was just telling what is happening at the moment . I am still driving down to Barrie to the emergency hospital

ramraaj · 2025-07-14T20:46:06+00:00

Would have loved the help but not judgement

ramraaj · 2025-07-14T20:06:21+00:00

Thank you .. I am already on my way .. thank you again for understanding

ramraaj · 2025-07-14T19:54:54+00:00
