Hello everyone!
I have a 2021 Tahoe LT with 80,000 miles. It's equipped with a Borla exhaust and cold air intake system. I'm experiencing a rattling noise at 25-30 mph, 42-45 mph, and 70-72 mph. The noise occurs when the engine is warm but not when the engine is cold, Weather doesn’t affect. It sounds metallic and seems to be coming from the back towards the middle. I've checked underneath, but nothing seems loose and it was also checked out by mechanics and nothing. The dealership hasn't been able to diagnose the issue, and I'm concerned it might be related to the torque converter. Any guidance or information would be greatly appreciated.
