Plastic bag bypassed air intake vent leading to the air filter and cut off all air flow to the engine while on the freeway. Auto completely went dead on a very dangerous part of the 205 overpass in West linn, Oregon. Large truck almost rear ended us from behind due to the sudden stop. Had car towed from West linn Oregon to curt warner Chevrolet in vancouver, Washington. Had car repaired by curt warner and wanted to know why the air intake vent was able to let foreign objects into the air intake vent and completely cut off all air flow to the engine. Would think all air vents on all cars are covered by a screen to prevent anything from covering the air filter. Curt warner would not cover the charges of $107.22 (labor = $74 & parts = $18.15, misc. Charges = $7.40, tax = $7.67) to replace the air filter and take a plastic bag off the air filter. Extremely concerned about this issue. Allot of 2000 Chevrolet Impala police cars may have the same problem while on duty. This will cause a accident. I sure hope no one has a fatality before GM corrects this dangerous problem.
