Hey everyone, I’m trying to figure out a strange rattle/noise coming from my 2018 Jeep Wrangler Sport S and I’m hoping someone here has experienced something similar.

The issue happens mostly when I’m lightly accelerating or trying to maintain speed/cruise. It sounds like a rattling or vibrating noise. The weird part is that if I press the gas pedal down hard and accelerate aggressively, the rattle completely goes away.

A few more details:

• 2018 Jeep Wrangler Sport S
• No check engine light
• Scanned the vehicle and there are NO engine codes stored
• Noise seems load/throttle dependent
• Happens under light to medium throttle
• Goes away under heavy throttle/WOT
• Vehicle still drives normally otherwise
• No noticeable loss of power
• No misfire codes
• No abnormal idle

I attached a video so you can hear the exact sound because it’s hard to describe through text alone.

Things I’m wondering about:

• Heat shield rattle?
• Exhaust issue?
• Timing/VVT related?
• Torque converter/transmission issue?
• Engine ping/detonation?
• Loose catalytic converter internals?
• Driveshaft/U-joint vibration?

I’d appreciate any ideas on what I should check first or if anyone has had this exact symptom before. Trying to narrow it down before I start throwing parts at it.

Thanks in advance.
