NHTSA Preliminary Evaluation PE10033 - closed, opened 2010-08-23.
NHTSA investigation PE10033 is a Preliminary Evaluation opened on 2010-08-23 and currently closed. The subject is tracked inside the Office of Defects Investigation queue. Latest activity on this investigation was logged on 2011-07-15 - NHTSA updates that field whenever an Information Request goes out, a supplement is filed, or a status change is recorded in the public docket.
A Preliminary Evaluation like PE10033 is the entry point of the federal defect-investigation process. NHTSA engineers scan complaint databases, field reports, and manufacturer data to decide whether an Engineering Analysis is warranted, whether a voluntary recall is already sufficient, or whether the pattern does not rise to a defect finding.
Investigators summarized the matter as follows: "The subject vehicles suffered from a design issue whereby water could run down onto the cowling under the hood and located in the area of the windshield wipers and then drip onto a computer module, the Powertrain Control..." Investigations are the early-warning layer of the federal auto-safety system, sitting upstream of formal recalls and defect orders. Whether this one closes without action or escalates into an Engineering Analysis, the full history stays in the ODI archive so researchers, litigators, and buyers can pull the paper trail at any time.
Investigation Summary
The subject vehicles suffered from a design issue whereby water could run down onto the cowling under the hood and located in the area of the windshield wipers and then drip onto a computer module, the Powertrain Control Module (PCM), which could be manifested in a variety of symptoms depending on which part of the circuit board became wet or which of the connector pins shorted out. In addition to causing an engine to stall, which may or may not then restart, the water intrusion could also cause the transmission to shift poorly, the vehicle to have erratic power, a malfunction indicator light to come on, or result in an inability to start the vehicle, an inability to shift the vehicle into either forward or reverse. Also the problem could cause a higher than normal idle RPM in Park, or for the radio to malfunction, or the interior lights to stay on. During this investigation ODI was concerned with the effect of the engine stalling or a drastic and sudden loss of power either of which may create a safety risk. In reviewing the actual number of these types of incidents, collectively referred to here as engine stalls, the number was found to be below what would be considered a defect trend. For example, the number of engine stalls identified in Ford's warranty claims for the model year (MY) 2004 subject vehicles, the MY with the most failures, was 200 out of population of 125,865, for a failure rate of 0.16%. The one crash recorded by a complainant to NHTSA, VOQ 10311522, alleged that the engine stalled, due to water intrusion into the PCM, while the road was turning causing her to go off the road and according to the police report the vehicle then hit an embankment and a tree stump. Ford reported in their response that there were three alleged crashes but none of these were validated as being caused by a problem with water intrusion into the PCM causing a stall. Accordingly this investigation is closed. The closing of this investigation does not constitute a finding b
About This Investigation Type
A Preliminary Evaluation (PE) is the first phase of NHTSA's investigation process. It is opened when the agency identifies a potential safety defect pattern, usually triggered by consumer complaints, manufacturer reports, or field monitoring. During a PE, NHTSA gathers information to determine whether a formal engineering analysis is warranted.
