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.
