Stallion preliminary evaluation PE15005
Loss of Windshield Wiper Function. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the linkages on 1 model year (2014). Opened Feb 27, 2015, closed Mar 26, 2016 after 13 months. It led to safety recall 16V152000. became a recall
What NHTSA says
Source: Office of Defects Investigation, as filedOn February 27th, 2015 the Office of Defects Investigations (ODI) opened this Preliminary Evaluation (PE15-005) to investigate multiple incidents of windshield wiper electrical system failures on Stallion 900 series motor coaches manufactured by Stallion Bus and Transit Corporation. It was reported to ODI that wipers would stop operating when the wiper motor changed speeds, and would not function again until the bus is powered down and restarted. During the investigation, the manufacturer found that the 12 to 24 volt power converter in the subject vehicle's wiper system could erroneously shut off when the wiper speed is changed. An over-current or voltage protection circuit of the power converter is erroneously activated. To remedy this defect the manufacture is modifying the 12 volt power-up converter to have the over-current protection and the voltage protection removed from the Power Control Buss. All vehicles built after these units would use a power converter supplied by a different manufacturer, or a modified converter with the protection circuits disabled. With the recall action 16V-152 taken by Stallion this investigation is closed as further use of agency resources does not appear to be warranted. The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 10630768, 10631041, 10633220, 10633236, 10632428, 10633201, 10633222, 10631019, 10631028, 10632409, 10632414
A Preliminary Evaluation is the first formal stage: NHTSA has decided the complaints and other information it screened are worth a closer look, and asks the manufacturer for its own data on the condition. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one became a recall. The campaign page carries the manufacturer’s filed defect, risk and remedy, the build window and every model year covered; whether one specific vehicle is included is settled by VIN at nhtsa.gov/recalls.

Common questions
Source: NHTSA Office of Defects InvestigationIs PE15005 a recall?
No — it is the investigation that led to one. Recall 16V152000 is the campaign; its page carries the remedy.
Is PE15005 still open?
No. It closed on Mar 26, 2016 and led to recall 16V152000.
Which vehicles does PE15005 cover?
NHTSA opened it on 1 model year: 2014 Stallion 900. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
