In a recent high-profile case, Nissan has recalled over 440,000 vehicles due to a potential engine bearing defect that could lead to engine failure and increase the risk of a crash.
In this article, we’ll explain what engine bearings are, why they’re important, common causes of bearing failure, how to identify early warning signs, and whether diagnostic tools like OBD2 scanners can help.
Every car diagnostic process should begin with a VIN check, because the VIN lays the foundation for what your Autel OBD II scanner will detect.But here’s what it doesn’t tell you:Your car’s current condition. That’s where a car diagnostic tool like the Autel MD906Pro comes in.
How does the new Autel MD909 Pro stack up against other scanners in the MaxiDiag series? What upgrades does it bring, what are its standout features, and how does it compare to larger tablet-style diagnostic tools? And of course—how much does it cost? Let’s break it all down.
