NHTSA Investigation PE89152
UNDER DASH FIRES
NHTSA Investigation PE89152 is a Federal defect investigation into the vehicle speed control:linkages on 1987 PORSCHE 944 vehicles, opened Aug 11, 1989. Investigations are triggered when the agency's Office of Defects Investigation (ODI) sees a pattern in consumer complaints, manufacturer warranty data, early-warning reports, or formal petitions filed by safety advocacy groups. The investigation is closed; closure can mean NHTSA found no defect trend, the issue was resolved through a manufacturer service campaign, or the case was converted into a formal recall. Below: the timeline, NHTSA-published documents, related recalls, peer investigations, and a list of motor carriers operating affected vehicles in the past 24 months.

About NHTSA defect investigations
The National Highway Traffic Safety Administration's Office of Defects Investigation (ODI) is the federal agency responsible for examining potential safety-related defects in motor vehicles and motor-vehicle equipment. ODI's authority comes from the National Traffic and Motor Vehicle Safety Act and 49 U.S.C. § 30118, which give NHTSA the power to compel manufacturers to recall defective products.
Investigations follow a two-phase escalation: a Preliminary Evaluation (PE) gathers consumer complaints, the manufacturer's first written response, and warranty data; if PE evidence supports continued review, the case escalates to an Engineering Analysis (EA) with crash testing, component teardowns, and a formal information request. About a third of PEs escalate to EA, and roughly half of EAs convert into a formal recall.
