Chevrolet Tahoe 2007–2014

3rd generation · GMT900 (GMT921/GMT922) · 4,266 complaints, 2,731 with mileage

Owners filed 4,266 complaints with NHTSA about the 2007–2014 Chevrolet Tahoe, and 2,731 of them record the mileage at which the failure happened. That is enough to show not just what fails, but when.

Failures are spread across the mileage range, with the middle half between 47,000 and 100,000 miles. The median is 73,000 miles.

The most-reported areas are the airbag system (29.5% of complaints, typically around 80,000 miles), problems owners could not categorise (23.2% of complaints, typically around 74,961 miles), body structure (16.1% of complaints, typically around 70,000 miles).

12 recall campaigns cover this generation.

Which systems, and when

Complaints about this generation are not spread evenly across the vehicle, and the systems that generate the most of them do not all fail at the same point in a car's life. The median failure across all systems here is 73,000 miles; the figures below show which parts of the car run ahead of that and which run behind.

The airbag system accounts for 29.5% of complaints (1,257 reports, 520 of them with a mileage figure), with a median of 80,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 55,340 and 112,000 miles.

A single system taking 29.5% of all complaints is a concentration worth noting. It means that for this generation, most of what owners reported came back to one area of the car rather than being distributed across many small faults.

Problems owners could not categorise accounts for 23.2% of complaints (990 reports, 665 of them with a mileage figure), with a median of 74,961 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 51,500 and 99,000 miles.

Body structure accounts for 16.1% of complaints (686 reports, 529 of them with a mileage figure), with a median of 70,000 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 48,000 and 90,000 miles.

The electrical system accounts for 8.1% of complaints (344 reports, 250 of them with a mileage figure), with a median of 71,606 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 36,000 and 110,000 miles.

The engine accounts for 3.4% of complaints (145 reports, 110 of them with a mileage figure), with a median of 99,500 miles, close to the vehicle's overall pattern. The middle half of these reports falls between 68,000 and 134,000 miles.

Latches and locks account for 3.3% of complaints (139 reports, 124 of them with a mileage figure), and they fail early — a median of 47,000 miles, well before the vehicle's overall median. Failures clustered this far below the rest of the car usually point to a design or manufacturing problem rather than wear, because wear does not selectively target one system on low-mileage examples. The middle half of these reports falls between 34,230 and 60,000 miles.

Differences between model years

Within this generation, complaint volume is not constant across model years. The 2007 model year drew the most — 1,532 complaints — while 2014 drew the fewest at 118. The median year sits at 398.

That makes 2007 an outlier: roughly 3.8 times the median year of this generation. A single year standing that far apart usually reflects either a first-year issue that was later corrected, or a component change introduced for that year. Anyone shopping this generation has a straightforward reason to prefer a different year, all else being equal.

Recalls and what they cover

NHTSA records 12 recall campaigns covering vehicles in this generation. A recall means the manufacturer or the regulator concluded there was a safety defect or a standard was not met, and that a free remedy is owed to owners — including second and later owners.

The campaigns cluster around the airbag system (5), the electrical system (3), the hydraulic brake circuit (1). Repeated recalls against the same area of the car generally mean the first remedy did not fully resolve the underlying problem.

Recall status is specific to the individual vehicle, not the model. Checking a VIN against NHTSA's lookup is free and takes under a minute, and it is the only way to know whether a particular car has had the work done.

Reported severity

Of the 4,266 complaints filed against this generation, 85 reported a crash; 45 reported a fire; 168 reported an injury; 1 reported a fatality. Crash-involved reports represent 2.0% of the total.

These are owner-reported outcomes, not verified investigations, and they are not adjusted for how many of these vehicles are on the road. They are included because the distinction between a fault that strands a car and a fault that causes a collision is the one that matters most, and it is not visible in a complaint count alone.

What this means if you are buying one

For a buyer, failures on this generation are spread rather than concentrated: the middle half falls between 47,000 and 100,000 miles, with a median of 73,000. There is no single mileage threshold to watch, which means condition and maintenance records are more informative than the odometer.

On inspection, the airbag system and problems owners could not categorise are where this generation's reports concentrate, so those are the areas worth a specific look. Problems owners could not categorise in particular shows a median failure mileage of 74,961, which gives a concrete number to compare against the odometer of any car you are considering.

None of this is a substitute for a pre-purchase inspection on the individual car. Aggregate patterns describe a population; the example in front of you has its own history.

Documented problems

Engine 2007-2014

Active Fuel Management (cylinder deactivation) lifter collapse: the collapsible AFM lifters stick or fail, causing misfire, a persistent tick, and in severe cases camshaft lobe wear requiring cam and lifter replacement.

Engine 2007-2014, settlement scope 2011-2014

Excessive oil consumption on the 5.3L LC9/LMG. The AFM pressure relief valve sprays oil at the piston skirts and the low-tension piston rings cannot control it, so oil is drawn past the rings and fouls spark plugs. A class-action settlement covered 2011-2014 vehicles with the LC9. Earlier 2007-2011 units were partly addressed with a rebaffled valve cover.

Interior

Dashboard cracking, one of the highest-volume non-safety complaints for this generation.

Steering

Power steering pump and hydraulic line leaks causing loss of assist.
