Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Traveling on interstate 57 during daytime hours. While cruising at 73 miles per hour in the right hand lane, the vehicle sputtered and lost all power. I coasted to a stop off the side of the road. I restarted the vehicle and everything seemed ok, so I continued on. A little later it sputtered again and started losing power. The power came back before it came to a complete stop. I called on star for a diagnostic check and they told me I had a fuel system problem and that if the car would run to continue that it was not a safety issue. …”

No leak was visible when I returned again on june 13th (21,126 miles) when the oil indicator went on again. The dealer found minor seepage due to the left rear of the oil pan. …”

Also, the vehicle had an oil leak. The dealership determined the leak was from the oil filter and corrected it. …”
