Wife's burb is having starting issues. I've taken the battery put and had it load tested, tested good. Tried my jump pack and it doesn't help. New battery in key fob. Sometimes it starts fine and sometimes the only way it will start is by putting the fob in the pocket in the consol, and sometimes it wont do anything, come back 5 minutes later and it starts right up. The lights will shut off and gauges will stick when you hit the start button. Sometimes the brake assist will pop up on the dash. I can't get it looked at until next week.

Any ideas?

First check your battery connections.

Change battery in fob and if your car battery wont start change it. May have a bad cell....

How old is the car battery? Battery cables on these can also cause problems. Check both ends and make sure they are clean and tight.
