Hi, Ive been dealing with an issue on my Infiniti for the past few weeks and honestly Im getting a bit stuck on what to do next. The car starts fine but theres a strange vibration when I accelerate, especially on highways, and my regular workshop just keeps saying its normal wear and tear without really checking deeply. I started searching online and came across a place mentioning Expert Infiniti Technicians Musaffah but Im not sure if its actually worth switching from my current mechanic or if its just the same thing with a different name.

What I really want to know is whether anyone has actually taken their Infiniti to a specialist in that area and felt a real difference compared to general garages. I dont mind paying a bit more if the diagnosis is accurate and I dont have to keep going back again and again for the same problem. My main worry is getting stuck with trial and error repairs, because that usually ends up costing more in the long run.

Also curious about how honest these specialist workshops are with parts. Do they usually suggest genuine parts only, or do they also push cheaper alternatives without clearly explaining the difference? I rely on my car daily, so I just want something reliable and straightforward at this point. Any real experiences or advice would really help me decide what to do next.

A vibration that only shows up on acceleration is usually not just normal wear, that sounds more like a drivetrain or engine mount issue. I'd get a second opinion before accepting "wear and tear" as the final answer.

Your current workshop brushing it off without a deeper check is a bit concerning honestly, especially on the highway where it matters most. A specialist would usually run a proper diagnostic instead of just guessing it's normal. Worth at least getting one second opinion before deciding to switch permanently.

This sounds like something worth taking seriously rather than ignoring, vibration under acceleration can come from several different things like engine mounts, CV joints, or even balance issues, and "normal wear" is a vague answer that doesn't really explain anything. A specialist should be able to actually pinpoint which one it is instead of just dismissing it. As for parts, the honest ones usually explain the difference between genuine and aftermarket clearly and let you choose, rather than just picking one without telling you. If a place avoids that conversation entirely, that's usually not a great sign.

Ask for a clear explanation of what's actually causing the vibration before paying for anything. A shop that can't explain it specifically is probably just guessing.

I'd push for more than just "normal wear" as an explanation, especially since it's happening specifically at higher speeds which usually points to something mechanical rather than cosmetic. A good specialist should be able to walk you through what they're checking and why, not just throw a part at it and hope it helps. On the parts question, ask directly whether they default to genuine or aftermarket and have them explain the price difference clearly. Trial and error repairs really do add up fast, so getting one accurate diagnosis upfront is usually cheaper in the end.
