Online & FreeThe Truth About the Dealership Stellantis Audio Diagnosis Tool
Dealership technicians across the Stellantis network (formerly FCA / Chrysler Group) use specialized NVH (Noise, Vibration, and Harshness) software paired with the corporate wiTECH diagnostic microPod. This software records sound through chassis microphones to compare vehicle frequencies against factory acoustic databases.
Unfortunately, independent mechanics and vehicle owners cannot purchase this app without an active dealership dealer code and commercial subscription. Carithm provides the free consumer alternative — running neural audio recognition directly from your phone microphone to pinpoint known engine, transmission, and suspension faults in seconds.
Known Acoustic Failure Signatures Across Stellantis Vehicles
1. The Infamous Hemi Tick (Lifter & Camshaft)
A fast, metallic tapping sound from the cylinder heads on Ram 1500, Dodge Charger, and Jeep Grand Cherokee. Caused by oil starvation to MDS needle-roller lifters, flattening the camshaft lobe.
2. Ram / Jeep Exhaust Manifold Bolt Snap
Loud ticking upon cold start that fades after 3–5 minutes. Caused by thermal warping on the rear manifold studs snapping off in the cylinder head, creating an exhaust pulse leak.
3. Pentastar 3.6L Rocker Arm Needle Clatter
Distinct clicking or clattering near the valve cover in Jeep Wrangler and Grand Cherokee. Caused by worn rocker arm pivot bearings scoring the intake/exhaust camshafts.
4. ZF 8HP 8-Speed Transmission Whine
High-pitched turbine whine that increases with road speed. Typically indicates internal fluid aeration, clogged transmission pan filter, or front planetary gear wear.

Frequently Asked Questions
Can this replace an in-person dealer diagnostic scan?
Carithm acts as pre-inspection decision support. It identifies the high-probability mechanical component by sound before you pay a dealer $180–$250 for a standard diagnosis fee.
How can I tell a cold-start manifold tick from internal engine damage?
If the ticking noise disappears after your Ram 1500 or Jeep reaches operating temperature, it is almost certainly a broken rear exhaust manifold bolt. If it gets louder as you rev the engine while warm, suspect a lifter or rocker arm.
Does this tool work on European Stellantis brands (Peugeot, Citroën, Vauxhall)?
Yes. The acoustic analysis engine processes turbocharger whines, diesel injector ticks, and dual-mass flywheel rattles across all modern European and North American vehicle platforms.
