This technical report provides a synthesized analysis and categorization of documented owner complaints concerning multiple Fiat models. The purpose of this document is to furnish the Quality Assurance and Engineering teams with a clear, data-driven overview of recurring issues reported by vehicle owners. By systematically organizing these incidents, this analysis aims to highlight critical patterns and potential systemic weaknesses, thereby guiding future product improvement, validation testing, and recall management efforts.
The report is structured to provide a granular, model-by-model breakdown of all documented complaints. Each section is dedicated to a specific Fiat model and presents a detailed table categorizing reported incidents by the affected vehicle system. This is followed by a cross-model thematic analysis that identifies overarching issues prevalent across the product line.
The following sections will delve into the specific incident data for each model, beginning with the Fiat 124 Spider.
2.0 Fiat 124 Spider Incident Analysis
An analysis of the Fiat 124 Spider is crucial for understanding the specific failure modes and customer pain points associated with this distinct model. The primary reported issues are not concentrated in mechanical powertrain failures but rather cluster around two key areas: logistical challenges in executing safety recalls and performance anomalies within the electrical system, most notably the spontaneous activation of the vehicle alarm while in motion.
The table below provides a systematic summary of all reported incidents for the 124 Spider.

The prevalence of logistical and electrical system concerns on the 124 Spider provides a distinct contrast to the issues documented for the next model, the Fiat 128.
3.0 Fiat 128 Incident Analysis
The incident data associated with the Fiat 128 is notably sparse and anomalous. The three reported issues, logged against the SEATS, STEERING, and STRUCTURE:BODY systems, all share identical and non-descriptive complaint text. This uniformity suggests a potential data entry or quality issue within the source data. Nevertheless, the complaints are presented here for completeness and to document the anomaly.
