THROTTLE CONTROL MALFUNCTION
NHTSA Preliminary Evaluation PE05041 - closed, opened 2005-07-26 and involving the VOLVO VOLVO.
NHTSA investigation PE05041 is a Preliminary Evaluation opened on 2005-07-26 and currently closed. The subject of record is VOLVO VOLVO, which places this file inside the Office of Defects Investigation queue for VOLVO. Latest activity on this investigation was logged on 2005-12-07 - 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 PE05041 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: "PE05-041 WAS OPENED ON JULY, 26, 2005, BASED ON 136 CONSUMER COMPLAINTS TO ODI ALLEGING THROTTLE CONTROL MALFUNCTIONS IN THE SUBJECT VEHICLES. ODI HAS NOW RECEIVED 591 COMPLAINTS OF ETM FAILURES WHICH ALLEGE SYMPTOMS WIT..." 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. Related VOLVO files, listed below, give context on whether this is an isolated concern or part of a broader pattern across the brand.
Investigation Summary
PE05-041 WAS OPENED ON JULY, 26, 2005, BASED ON 136 CONSUMER COMPLAINTS TO ODI ALLEGING THROTTLE CONTROL MALFUNCTIONS IN THE SUBJECT VEHICLES. ODI HAS NOW RECEIVED 591 COMPLAINTS OF ETM FAILURES WHICH ALLEGE SYMPTOMS WITH POTENTIAL SAFETY RELATED CONSEQUENCES. THESE INCLUDE ALLEGATIONS OF ENGINE STALL, VEHICLE SURGING FORWARD WITHOUT ACCELERATOR INPUT, VEHICLE HESITATION UPON ACCELERATION AND SUDDEN AND UNEXPECTED TRANSITION INTO REDUCED PERFORMANCE OPERATION (LIMP MODE). VOLVO SUBMITTED OVER 2,900 COMPLAINTS CONCERNING THE ETM IN THE SUBJECT VEHICLES DURING PE05-041. ODI'S PRELIMINARY ANALYSIS OF A SAMPLE THE VOLVO COMPLAINTS IDENTIFIED APPROXIMATELY 55 PERCENT WITH ONE OR MORE OF THE SYMPTOMS DESCRIBED ABOVE. ODI IS CONTINUING ITS ASSESSMENT OF THE INFORMATION CONTAINED IN THE VOLVO COMPLAINTS. IN NOVEMBER 2005, TO RESOLVE AN INVESTIGATION BY THE CALIFORNIA AIR RESOURCES BOARD, VOLVO ANNOUNCED THAT IT WOULD EXTEND THE WARRANTY COVERAGE TO 10 YEARS / 200,000 MILES FOR THE ETM IN APPROXIMATELY 356,000 MODEL YEAR 1999 THROUGH 2002 PASSENGER CARS SOLD IN THE UNITED STATES AND CANADA. UNDER VOLVO'S POLICY, VEHICLES THAT EXPERIENCE ETM FAILURES WILL RECEIVE A VARIETY OF REPAIRS INCLUDING ETM CLEANING, REPROGRAMMING THE ENGINE CONTROL MODULE AND/OR REPLACEMENT OF THE ETM. THIS INVESTIGATION HAS BEEN UPGRADED TO AN ENGINEERING ANALYSIS (EA05-021) TO CONTINUE TO ASSESS THE SAFETY CONSEQUENCES OF ETM FAILURES IN THE SUBJECT VEHICLES.
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.
