Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Repeated driving within 1/4 mile of the indianapolis regional air traffic control radar antenna causes some of the instrument panel failure indicators to turn on for several seconds. The battery and airbag indicators turn on and clicking noise is heard from the instrument panel. The lamp indications are about the same as when the engine is first started. My concern is that this may be doing damage to the computer which could result in a future failure.”
NHTSA complaint #10429240, filed 2011-10, 112,000 miles“While driving at low speed vehicle stalled. Consumer managed to pull over, and had the vehicle towed. Dealership was notified, but did not resolve the problem.”
