The Chevrolet Tahoe has built a long reputation as a big, tough family hauler, but not every engine choice in its lineup deserves blind trust. If you are shopping for one, there is a specific 6.2-liter V8 that has turned into the trouble spot, and it is worth knowing why before you sign anything.
The Tahoe itself has been around since 1992, and its roots go back even deeper through Chevy’s full-size truck platform. That long run means the SUV has seen plenty of different powertrains over the years, and like most vehicles with a long history, some setups have aged far better than others.
Most Tahoes on the road rely on a familiar GM V8 formula, and the current truck offers three engines. Buyers can stick with the base 5.3-liter V8, step up to the 6.2-liter V8, or go with the 3.0-liter Duramax turbodiesel inline-six. On paper, that gives shoppers a nice spread of power, towing ability, and efficiency.
The engine that causes the real headache is the L87 6.2-liter V8. It is the one to watch out for because its problems go beyond annoying quirks and into the kind of failure that can leave a vehicle dead in its tracks. That is a serious hit for an SUV like the Tahoe, which is supposed to feel solid and dependable.
This particular 6.2-liter is not the same thing as every other GM 6.2 V8 that has worn a badge over the years. GM has used earlier versions like the L92 and the EcoTec3 L86, but the L87 is the newer design that started showing up in the 2019 Silverado before reaching the Tahoe in 2021.
The big issue with the L87 is bearing failure, and that points to a manufacturing defect rather than ordinary wear and tear. Because the problem is buried inside the engine, it is not the sort of thing that can be brushed off with a quick repair, and when it goes bad, the whole engine can fail.
That is why this has become such a mess for GM. The company has had to recall more than 700,000 L87-equipped trucks and SUVs from the 2021 to 2024 model years, and the issue has also drawn an NHTSA investigation. When a powertrain problem reaches that level, it stops being a bad rumor and starts becoming a major ownership concern.
GM has tried to get ahead of the problem with engine replacements for affected vehicles and by moving to higher-viscosity oil. Even so, the fix has not exactly restored confidence, especially with reports that more than 30 owners whose engines were supposedly repaired have still seen failures afterward.
That leaves shoppers in a tricky spot, especially if they want a late-model Tahoe but do not want to gamble on a risky V8. GM says it updated the production design for 2025 and newer engines, which kept those models out of the recall, but some owners of those newer trucks have still reported issues with their 6.2s.
If you want to dodge the drama, there are cleaner choices in the Tahoe lineup. The base 5.3-liter V8 gives up some power, and the 3.0-liter Duramax turbodiesel may not be the loudest choice in the room, but it brings strong torque and solid fuel economy to the table.
That tradeoff may end up looking pretty smart if you want a Tahoe that feels capable without the baggage. GM’s next wave of truck engines is coming, including a new 6.6-liter V8 for the redesigned 2027 Silverado, and that change will likely spill over into the Tahoe before long.
For now, the safest move is simple enough: pay close attention to which engine sits under the hood. The Tahoe still has plenty going for it, but the L87 6.2-liter V8 has earned its reputation for all the wrong reasons, and that is one spot where caution beats regret every time.
