I've made so far 8 auto payments online and I would say almost half (4 times) of the times it goes without a problem. The problem isn't so much with the actual transaction as it is to simply sign in! I sign in and then I get the,"Ally Auto isn't available right now. We'll have things back up as soon as possible. Thank you for your patience." So of course I now have to wait until the next day or continue to check throughout the day. Not a way to do business in the 21st century! I would definitely not bank with them if this is the service, lack of, that I have to go through for just the auto payment.
I've used Ally for several years. I love that they do not charge a ton of fees, and they reimburse ATM fees charged by other banks. However, the only way to deposit is by either an eCheck or mailing in a check. Their website advertises next day availability, however I have never had an eCheck deposit post in that time frame. They always take a week. According to them, this is because my account has too many over drafts. I've had two in the past year, while waiting for a deposit to post. They're awesome if you direct deposit everything, but check deposits, try to avoid them if you can.
Tried to transfer $250K into Ally. They transferred it TWICE. Overdrew me at my bank. Took DAYS to get straight while my money did not earn interest. Excuses, excuses, excuses.....don't think they'll get any of my business again.
