Reliability report · 2023 Chevrolet Tahoe · Updated July 2026

The engine story hardens — this is a near-pure 6.2L failure year, and owners report the recall fix not sticking.

2023 is where the fifth-generation Tahoe's engine problem stops being one issue among many and becomes the whole story. The recent complaint file is overwhelmingly 6.2L V8 failures — total engine failure, a spun bearing under 24,000 miles, metal in the oil, and the truck shutting off at 55 to 77 mph. Recall 25V274 (2021–2024) is meant to catch it with an inspect-repair-or-replace remedy and a 10-year/150,000-mile special coverage, but the standout pattern here is owners reporting that their truck passed the recall inspection and then died anyway — a reason to treat a passed inspection as reassuring, not conclusive.

GM also acknowledged the family directly on 2023 builds with two Customer Satisfaction Programs: one replaces the engine for oversized lifter bores (a DFM-lifter root cause), the other replaces the transmission for low-hardness pinion gears. Away from the engine, 2023 adds an independent-rear-suspension control-arm-bolt recall (23V642) and a low-brake-fluid-warning software recall (24V674). A 5.3L 2023 without engine history is a far calmer buy than a 6.2L; on any 6.2L, the engine paperwork is the purchase.

Canary status

Squawking

What that means: 196 federal complaints and five recalls, and the recent file is dominated by one thing: 6.2L V8 engine failure under recall 25V274. The alarming pattern in the complaints is owners whose trucks passed the recall inspection and then failed anyway. GM also ran two 2023 engine/transmission replacement programs, one tied to the Dynamic Fuel Management (DFM) cylinder-deactivation lifters. On a 6.2L this is the year to be most careful; a 5.3L is a calmer buy.

6.2L V8 engine failure — recall 25V274, and the fix that doesn't always stick

major
  • 6.2L V8

This is the 2023 story. GM's recall 25V274 covers 2021–2024 6.2L Tahoes for connecting-rod and crankshaft defects that cause sudden engine failure, and the 2023 file is dominated by it — total engine failure, spun bearings under 24,000 miles, metal in the oil, and the truck dying at highway speed. The remedy inspects and repairs or replaces the engine free with higher-viscosity oil, plus a 10-year/150,000-mile special coverage. The pattern owners report on 2023 specifically is the worrying part: several passed the recall's inspection test and then had the engine fail anyway. Treat a completed inspection as necessary but not a guarantee; prefer a truck that got a replacement engine, and keep the special coverage in mind on any 6.2L.

This is a 6.2L V8 problem. The 5.3L V8 and 3.0L Duramax diesel don’t share it.

Engine and transmission replacement programs (lifter bores, pinion gears)major

  • 5.3L V8
  • 6.2L V8

GM acknowledged the drivetrain family on 2023 builds with two Customer Satisfaction Programs — the quiet, VIN-specific version of a recall. One covers engines whose lifter bores were machined oversized (a root cause of the Dynamic Fuel Management, or DFM, lifter failures), with the remedy being a full engine replacement. The other covers transmissions with low-hardness pinion gears, with the remedy being a transmission replacement. Neither states a mileage cap in the bulletin. On a 2023, run the VIN against both programs and ask whether either was performed — a replaced engine or transmission on this year is a plus, not a red flag.

10-speed transmission harsh shiftingmoderate

The 10-speed automatic can shift harshly, hesitate, or fail to shift, with the file showing deceleration events and transmission failures that in some cases accompanied the engine trouble. The 15-year/150,000-mile control-valve Special Coverage was scoped to 2021–2022, so it does not cover 2023 — meaning an out-of-warranty transmission repair here is out of pocket unless the pinion-gear replacement program applies. Test-drive for harsh or delayed shifts and factor a 2023 10-speed's lack of the control-valve coverage into the price.

Rear-suspension control-arm-bolt recallmoderate

Recall 23V642 covers 2023 Tahoes whose rear suspension outer control-arm bolts may not have been properly heat-treated and can break, misaligning the rear wheel — an item specific to the fifth generation's independent rear suspension. Dealers replace both bolts free. It's a straightforward fix, but confirm by VIN that it was done; a broken suspension bolt is a handling hazard.

Our vehicle passed their inspection required test for the engine recall and then at an intersection just died with absolutely no warning.
