Hey guys, I just bought a used 08 Infinity G37s today and everything was going perfect with it. The engine sounds great, good braking, ect. About a couple hours later I was driving it and I started hearing a random buzzing/vibrating noise, it was almost like a sup woofer buzz. The vibrating noise would stop when i stopped accelerating and usually when i accelerated again it wouldn't happen, it was just very unpredictable at the time. I started trying to figure it out more and i saw that at around 35mph it would start buzzing and i wouldn't be able to go any faster during this vibration. I slowed down and sped up and it worked fine again going over 40 seemed to not have any issues just getting to 40 was a struggle. Anyone got any ideas on what could be causing this? Thanks.

 

EDIT: The TPMS light is on, could that impact it?

 

definitely get the tpms light looked at and while thats being inspected, i would check the wheel bearings at the same time. tpms malfunction light is not going to cause any abnormal noise or vibration but a bad wheel bearing can.

 

Check grounding points
