The 2024 Buick Envision runs GM's 2.0L turbo paired with a 9-speed automatic. Being essentially brand-new, hard failure data is thin, but the repair job frequency hints at early engine carnage—piston, bearing, and head gasket work on a current-year vehicle is a major red flag pointing to potential oiling, cooling, or assembly defects.
Symptoms: Severe knocking or rattling from engine bay, Metal shavings in oil, oil pressure warning light, Sudden loss of power, white or blue smoke from exhaust, Check engine light with misfire codes
Fix: Complete engine rebuild or short-block replacement required. 18-24 labor hours for short block R&R; full rebuild with machine work pushes 30+ hours. Often covered under powertrain warranty if caught early, but out-of-pocket is catastrophic.
Estimated cost: $8,000-15,000
Transmission Oil Cooler Leaks
Occasional · medium severity
Typical onset: 20,000-60,000 mi
Symptoms: Transmission fluid puddles under vehicle (red or brown fluid), Overheating transmission warnings or limp mode, Fluid level drops rapidly between checks, Coolant contamination if internal cooler failure (milky fluid)
Fix: Replace transmission oil cooler and lines. 3-5 hours labor depending on cooler location (integrated vs external). Flush transmission and cooling system if cross-contamination occurred. Early catch avoids transmission damage.
Estimated cost: $600-1,200
Head Gasket Failure (Both Heads)
Occasional · high severity
Typical onset: 15,000-50,000 mi
Symptoms: White smoke from exhaust, sweet smell, Coolant loss with no visible external leaks, Overheating, bubbles in coolant reservoir, Oil appears milky or foamy on dipstick
Fix: Replace both head gaskets, resurface heads if warped. 14-18 hours labor. Should also inspect block deck for warpage and turbo for coolant ingestion. Given the mileage this occurs at, suspect factory defect or torque spec issue.
Estimated cost: $3,500-5,500
Transmission Mount Failure
Common · low severity
Typical onset: 30,000-70,000 mi
Symptoms: Clunking when shifting from park to drive/reverse, Excessive vibration at idle, especially in drive, Visible sag or torn rubber on mount during inspection
Fix: Replace failed transmission mount. 1.5-2.5 hours labor. Access is decent on this platform. Replace both motor and trans mounts together if one has failed—the other is usually close behind.
Estimated cost: $350-650
Fuel Filter Clogging (Premature)
Occasional · medium severity
Typical onset: 10,000-40,000 mi
Symptoms: Loss of power under acceleration, hesitation, Hard starting or long cranking times, Rough idle, engine stumbling, Check engine light with fuel trim or pressure codes
Fix: Replace in-tank fuel filter assembly. 2-3 hours labor (drop tank or access through rear seat depending on variant). Suspect contaminated fuel from factory or early corrosion in tank. Recommend fuel system cleaning after replacement.
Estimated cost: $400-750
Owner tips
Change oil every 5,000 miles with quality synthetic—this turbo engine is unforgiving of oil neglect and early bearing failures suggest marginal oiling design
Monitor coolant and oil levels obsessively in first 50k miles; head gasket and piston failures often give subtle warning signs first
Insist on extended powertrain warranty if buying new or CPO—the engine rebuild frequency is not normal for a current-year platform
Check transmission fluid color monthly; cooler leaks can destroy the 9-speed quickly if cross-contamination occurs
Hard pass on a used 2024 Envision until the engine carnage pattern is explained—catastrophic failures at 20k-40k miles point to serious factory defects that may not be fully resolved yet.

General Motors, LLC (GM) is recalling certain 2024 Buick Envision vehicles. The vehicles are missing the label that states the tire size, pressure, and the loading information. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims."
Consequence: Missing tire and load rating information may result in driving with improperly inflated tires or an overloaded vehicle, increasing the risk of a crash.
Remedy: Dealers will install the label, free of charge. Owner notification letters were mailed November 1, 2024. Owners may contact Buick Customer Service at 800-521-7300.
Size-standard part numbers — verify your connector type before buying. Rear blades are model-specific; check the package's vehicle list.
