Odometer readings owners gave when they filed. About half of all complaints include one.
A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.
Reports where the owner recorded a crash, a fire, an injury or a death.

EXTERIOR LIGHTING
THE LOW BEAM HEADLIGHTS WENT OUT SIMULTANEOUSLY WHILE I WAS DRIVING AT NIGHT. I PROCEEDED TO THE AUTO PARTS STORE, BOUGHT NEW BULBS AND CHANGED THEM OUT BUT THEY STILL DID NOT COME ON. ALL OTHER LIGHTS ARE WORKING INCLUDING THE HIGH BEAMS. I SEE THERE ARE RECALLS FOR THE SAME PROBLEM LISTED ONLINE FOR 2007 TB'S BUT WHEN I CHECKED WITH GM/BUICK I WAS INFORMED THAT MY VIN WAS NOT LISTED IN THE RECALL DUE TO IT NOT BEING ON THE PRODUCTION LINE AT A CERTAIN PLANT. YET WITH FURTHER RESEARCH THERE ARE NUMEROUS COMPLAINTS FROM OTHER TB OWNERS WITH THE SAME ISSUE AS THE RECALLED VIN'S WHICH SHOULD SHOW THIS IS A PARTS ISSUE. I WAS REFERRED TO THE DEALERSHIP BY GM/BUICK A DIAGNOSTIC OF WHICH I WILL HAVE TO PAY FOR BECAUSE MY VEHICLE WAS ON A DIFFERENT PRODUCTION LINE FOR A PART THAT CLEARLY APPEARS TO BE DEFECTIVE!

FUEL SYSTEM, GASOLINE
THE GAS GAUGE ON OUR 2007 CHEVY TRAILBLAZER HAS STOPPED WORKING. THIS NEARLY CAUSED AN ACCIDENT BECAUSE SUDDENLY I THOUGHT I WAS LEAKING GAS ON THE FREEWAY AFTER RECENTLY FILLING UP. THE CAR IS 3 YEARS AND 2 MONTHS OLD WITH 42,000 MILES. THIS SEEMS TO BE A COMMON DEFECT JUDGING BY THE COMPLAINTS ON THE INTERNET. CHEVY/GM WILL NOT PROVIDE ANY ASSISTANCE IN FIXING THIS KNOWN DEFECT OTHER THAN CHARGING $800+.
