It's been two years since I bought my Jeep and since day one the radio hasn't been able to keep an accurate time. I sync my radio clock with my cell (since it's the most accurate) and after one to two days it's off by at least 3-5 minutes. If I let it go longer than a few days it can be off by up to 8 minutes. It's been mentioned to the dealer but the dealer has no idea what it could be and this is the first time they've heard about the issue.
