Greetings! Feels great to join Titan family! Just bought a used 2018 Nissan Titan Pro-4x King cab with 18,000 miles on it. Already put 4000 miles on it within a month, Took me through a lot of rough trails. However I did notice a weird sound when switched to 4lo. It mainly happens when using the brake especially when I activated hill descent control when going down steep hills. The sound is like when you hold a bouncy metal ruler at edge of a table, leave half of it outside the edge, press the loose end and let go of it. It will just bounce and make that kind of sound. Not every time I brake at 4lo, but almost all the time when hill descent control is on. I searched over the internet, someone said it might be the ABS kicking in. And it do have a feedback on brake pedal like when you hit brake hard and ABS kicked in. But I've never heard this kind of noise on my previous SUVs or sedans when ABS is activated. Anyone has similar experiences? Thank you so much!
