The 2007CHEVROLETBLAZER carries 11 consumer safety complaints in NHTSA's Office of Defects Investigation database for this specific model-year cohort. Within that volume, owners reported 2 crashes, 0 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2007 BLAZER is fuel system, gasoline with 5 filings, followed by exterior lighting (2) and fuel system, other:storage:fuel gauge system (1). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability.
NHTSA currently has 57 investigation files overlapping the 2007 BLAZER, and 2 remain open. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

20161130EXTERIOR 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! *TR

20100712FUEL 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+. *TR
