| EA11001 | GENERAL MOTORS CORP. | 01/05/2011 | Brake line corrosion failure | |||
| The office of defects investigation (odi) received defect petition dp10-003 on march 2, 2010, requesting the investigation of model year (my) 2003 chevrolet silverado 2500hd 4wd pickup trucks for corrosion failures of the vehicle brake lines.dp10-003 was granted and on march 30, 2010, preliminary evaluation pe10-010 was opened on more than six million model year 1999 through 2003 light trucks and sport utility vehicles manufactured and sold by general motors corporation (gm).on july 2, 2010, odi received gm's response to an information request, which included gm's assessment of the frequency and safety consequences of the alleged defect. gm stated that:(1) the brake system of the subject vehicles is split front/rear and should a brake pipe suddenly fail for any reason, the affected vehicle would be capable of stopping with the pressure supplied by the remaining circuit; (2) the subject vehicles were designed to meet the hydraulic circuit partial failure requirements of federal motor vehicle safety standards 105 and 135, light vehicle brake systems; and (3) should a brake fluid leak occur for any reason, the brake system malfunction indicator lamp (mil) would illuminate and warn the driver before the brake fluid level was low enough to cause a loss of line pressure. of the890 total complaints for brake pipe corrosion identified, 761 were located in salt belt states (connecticut, delaware, district of columbia, illinois, indiana, iowa, maine, maryland, massachusetts, michigan, minnesota, missouri, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, west virginia and wisconsin).the complaint rate per 100,000 vehicles sold is significantly higher in the salt belt, 43.0, compared with 3.0 for the remaining states.in approximately 25 percent of the complaints, the brake pipe failure has allegedly occurred suddenly, with no warning to the driver (i.e., no brake warning light), and resulted in extended stopping distances.in 26 of these incidents, the increase in stopping distance that resulted was alleged as a factor in a crash and in 10 others the vehicle was intentionally steered off the road or into another lane of travel in order to avoid a crash.an engineering analysis has been opened for subject vehicles sold or currently registered in salt belt states to further assess the scope, frequency and safety risks associated with sudden failures of corroded brake pipes that can result in decreased brake effectiveness. odi will continue to gather information on subject vehicles outside the salt belt as well. | ||||||

| PE05020 | GENERAL MOTORS CORP. | 04/28/2005 | 09/13/2005 | UNWANTED LOW-SPEED ABS ACTIVATION | 05V379000 | |
| In a letter dated august 29, 2005, gm notified odi that it was recalling certain model year 1999 through 2002 c/k pickup trucks and sport utility vehicles to correct a problem with anti-lock brake system (abs) wheel speed sensor corrosion that may result in unwanted abs activation and extended stopping distances during low-speed braking (recall 05v-379).gm's recall covers approximately 804,000 vehicles currently registered in the following 14 salt-belt states:connecticut, illinois, indiana, massachusetts, maine, michigan, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, and west virginia.the recall procedure will involve removing the sensor, cleaning the mounting surface, applying a rust inhibitor (zinc-x) to the surface, and reinstalling the sensor.if necessary, the sensor will be replaced. the population and failure report data given in this resume are for the full region that has been considered by odi as the salt-belt.that includes delaware, iowa, maryland, minnesota, missouri, wisconsin and the district of columbia in addition to the 14 states included in 05v-379.the states covered by gm's recall have the highest incident rates for the subject condition, accounting for 91% of the incidents, but only 24% of subject vehicle sales in the united states.odi's analysis determined that 840 of the complaints, 244 of the crashes, and 16 of the injuries identified in this investigation occurred in those states.the resulting incident and crash rates are 96.2 and 28.0 per 100,000 vehicles respectively (note:rates are based on vehicle sales, not registered vehicles). the corresponding numbers in the excluded portions of the salt-belt are 399,000 vehicles, 81 incidents (20.3 per 100,000 vehicles), 3 crashes, and no injuries.the statistics in the remaining 30 states are 2,406,000 vehicles, 168 incidents (7.0 per 100,000 vehicles), 31 crashes, and one injury.gm and odi are continuing to monitor the problem experience in states that are not included in the recall.gm will provide odi with updated complaint, field report, and warranty data in november 2005.odi and gm will review that data and assess the appropriateness of the current scope of the recall at that time. | ||||||

| Gm is conducting a recall on all subject vehicles build between may 1999 and october 14, 1999.significant changes were incorporated into production in early october 1999, and vehicles built after that date have lower warranty failure rates.the complaint and warranty data appear to support the effectiveness of these changes. gm made additional changes in november 1999, february 2000, may 2001, and february 2004.odi will continue to monitor this problem and will take further action, if warranted, in the future.for further technical details see the attached engineering analysis report. | ||||||
