What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2007 Chevrolet Blazer, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
THE FUEL GAUGE WAS NOT READING THE CORRECT AMOUNT OF FUEL IN THE TANK. THE PUMP IS FINE BUT THE GAUGE IS NOT READING CORRECTLY. *TR
GAGE BECAME ERRATIC, NOT ACCURATELY REFLECTING AMOUNT IN THE TANK, READ FULL WHEN NOT...LOW FUEL LITE CAME ON WHEN THERE WAS FUEL IN THE TANK, SOME TIME WHEN STARTED IT REFLECTS, WE THINK ACCURATELY, THEN THE NEXT TIME DOES NOT-STAYS ON FULL AND OVER 30 MINUTES MAY GRADUALLY EASE ITS WAY DOWN. I HAVE 3 FRIENDS AT WORK WITH SAME ISSUE, SAME VEHICLE. *TR
Too few reports in this category for a page of its own — they appear in the full complaint list.
Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
HEADLIGHTS STOP WORKING SEVERAL TIMES WITH NO WARNING. DRIVERS SIDE POWER WINDOW HAS BEEN REPLACED 3 TIMES. ON THE HIGHWAY .IT IS VERY SCARY WHEN YOU LIGHTS QUIT WORKING. YOU HAVE TO TURN ON BRIGHTS TO BE ABLE TO SEE.
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
