Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The left turn signals (front, rear & dash) blink faster than the right ones indicating a burnt out bulb even though the left bulbs work. We replaced the front & rear bulbs twice and they worked normal for a short period of time. Then they revert to blinking fast. I replaced the bulbs the first time and the dealership service center replaced the bulbs the second time. There must be something wrong in the electrical system. I've noticed this with other Grand Marquis also.”
