Hi everyone, I am honestly feeling pretty worried right now and I hope someone here can calm me down or at least give me real talk. I have an Infiniti FX35 that I absolutely love. I have had it for about four years and I always tried to take decent care of it. But lately something terrible has been happening. The engine started making this tapping noise a few months ago. It was quiet at first only when the engine was cold. I stupidly ignored it because the car was still driving fine. Then the noise got louder. Now it sounds like someone is hitting a metal spoon against the engine block. It gets faster when I press the gas. Last week the check engine light started flashing and the car lost power while I was on the highway. I managed to pull over safely but I was shaking. I had it towed to a nearby garage and the guy there said he thinks it might be a rod bearing or something internal. He said fixing it would cost more than the car is worth. I almost cried honestly. But here is the thing. That garage was just a normal general shop. They work on all kinds of cars but I do not think they specialize in Infinitis. I am wondering if I should get a second opinion from someone who actually knows these engines. I found a place online that claims to offer expert Infiniti engine repair solutions and they seem to focus only on our brand. Before I spend a fortune towing my car again I want to ask if any of you have been in a similar situation. Did you have an engine noise or failure that one shop said was hopeless but another shop was able to fix reasonably? I know internal engine work is never cheap but maybe there is a difference between a rebuild and a full replacement. Also how do I know if the engine is truly dead or if it just needs something like lifters or timing chain tensioners? I really do not want to give up on this car because I cannot afford a new one right now. If any of you have had engine work done on your Infiniti please tell me what the experience was like. Did the car run good afterwards or did problems keep coming back? I just need some hope or honest advice before I make a decision that I might regret. Thanks everyone for reading my long sad story.
