Best I know of...
I give it 5 stars because of all the apps that are out there, this is the best that I know of!!! My friends with their BMWs, Mercedes, etc. have nothing compare to this app and they are envious as I’m warming up my car using the app while out to dinner. I love it even though sluggish (slow) at times but it does the job!!! Can it be better, ABSOLUTELY, but no other make of car has anything over GM so I give you your praises especially because you made the app available on my Apple Watch so the days I’m walking to my car and can’t quite get to my phone I just open up the app on my Apple Watch and presto my car is started and yes sometimes it takes a minute and yes sometime you have to redo it because it didn’t take the 1st time, but I have the ability to start my car, open or lock my car doors from my wrist!!! You can’t ask for anything better today!!! I encourage GM to work out the bugs but great so far!!! You have my vote!!! I love my Buick, the app and my car!!! 😆😘😆
Annoyed sometimes furious
Mybuick app used to be amazing. But ever since this UI update, I've have nothing but problems. It's very annoying to have to hold the button icon down so long in order to send a signal. It's weird. I didn't have to before. The thing that I hate.... Absolutely hate!... It's the UI screen lock and unlock buttons. They tend to be faded out. I can't lock or unlock my vehicle. Today my hands were full and couldn't get to my key fob. I figured I'd lock it with the app when I get inside. As of right now... The unlock is faded. Can't touch it. The lock button is bright but it says locked. But my door is unlocked. There is no way to lock it. I push it and nothing happens. At either time one or the other will be faded and unable to be pressed. This is common. I'll have to go to my car in order to lock the door. Major inconvenience because I'm in an apartment. It's a long walk to my car and I'm undressed. I pay a monthly full for this app I'm furious. But this has happened ever since the user interface update. It looks good but doesn't work good. I keep having to delete and reinstall the app just for it to happen again!
Safety & Security? None.
My elderly parents have a Buick LaCrosse that WAS in great condition, until the VIN was somehow RELEASED to several USERS in our area. We have had people REMOVING items from our vehicle when securely parked, the Intelilink computer, literally taken over by passerby’s, allowing them to “Listen in” to ALL conversations in the vehicle, pirate the Radio Am/Fm AND XM. Also the transmission has been “messed” with, I’m assuming the vehicle speed sensor, RPMS literally JUMP while we are driving down the road! This intrusion has cost my parents and myself a good amount of money, replacing stolen, destroyed, AND the damage done to the transmission is inevitably going to add to this accumulation of OUR money spent. How are these people able to obtain this info? Diagnostics as well. Shutting down the power steering, then after purchasing power steering fluid, we get back to the vehicle and it is no longer displaying the “power steering fluid” dummy light and works fine. Who should we turn to for reimbursement? And why on God’s green earth is there no way to LOCK others out of this vehicle? Highly unsafe, especially for my 82 year old mother. EXTREMELY disappointed. Looking forward to hearing from your company.
