Alfa Romeo Giulia (and Stelvio) models have an exposed powertrain ground strap under the vehicle body. Because of the exposed position of the ground strap it is prone to corrosion which causes the fine wire braid of the ground strap to become brittle and break. Breaking of the strands of wire is further accelerated due to the acute 90 degree bend in the ground strap routing resulting in wire fatigue. When the ground strap fails it is typical the vehicle may not start. With continued attempts to start, alternate grounding paths may be sought by the current from the starting circuit. This results in substantial and expensive damage to other wiring and electrical components within the engine bay. Alfa Romeo is aware of design flaw of exposed ground strap and the resulting damage from their choice of placement (and lack of protection of the ground strap). …
