Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have a 1999 Pontiac Montana with a 3.4ltr engine. After 40,000 miles I began have fuel injector malfunctions. On august 4, 2004, after several injector cleanings, I decide to have all the injectors replaced with oem GM injectors. Unfortunately this did not cure the problem since I have later discovered, the oem injectors for GM's 3.4ltr engines have an inherant defect - the magnet that is used to open and close the injector is very weak. When ever the injector encounters small dirt particles the injector remains shut, therefore causing the cylinder to misfire. …”
NHTSA complaint #10121607, filed 2005-05, 40,000 miles“Dt: consumer's wife filled gasoline tank up in richmond and drove home 125 miles and the tank ran almost empty. This was a 26 gallon tank. The emergency/low fuel light illuminated. When she got home there was a strong odor of gasoline coming form the car. Consumer turned on the ignition and there was immediate gushing of gasoline at the conjunction of where the plastic and metal fuel lines met right under the front driver's seat. Did not take vehicle to a dealer because warranty expired. Consumer jacked car up and removed the intermediate line and the fuel supply line was slightly melted. …”
NHTSA complaint #10134056, filed 2005-08, 51,000 miles“Fuel pump failed with only 43000 miles on the vehicle. Repair shop said that it is very rare for a fuel pump to fail with such few miles.repair bill for problem was $705. The reason I own newer vehicles is so I do not have to spend time and money at a repair shop. With my car payment and the cost of the repair I will have spent $1055 in one month to keep up a 1999 vehicle, which is rediculous.”
NHTSA complaint #734782, filed 2000-10“I writing to express dissatisfaction 2 major component failures occurred on a vehicle with less than 50,000 miles. The intake leak appears to be a known problem - buyer beware. I can understand disc pad wear, but not major brake system replacement/repair. The mechanic also noted excessive lifter noise; I fear this observation will lead to more major repair work. The dealer has been responsive. My complaint is intended for the manufacturere and other consumers. …”
