On the 2024-2026 Buick Envista 1.2L turbocharged I3 (LIH), the Envista's only engine, GM's turbocharged 1.2L three-cylinder (LIH), is the subject of a class action filed March 7, 2026 in California naming the 2024-and-later Buick Envista alongside the Encore GX, Chevrolet Trax and Trailblazer that share the engine. The complaint alleges internal engine components, oil lubrication passages and block casting features allow rod-bearing oil starvation, leading to spun bearings and broken connecting rods at very low mileage. NHTSA complaints filed against the Envista specifically match the pattern: ODI 11705232 (2024 Envista) reports the engine destroying itself while driving; ODI 11693273 reports the engine seizing on the road and restarting with a check-engine light and reduced-power message. Owners describe a loud knock or bang, a 'Reduced Engine Power' message, then stall. The lawsuit cites GM bulletins 20-NA-084, 23-NA-122, 23-NA-141 and 24-NA-021 as evidence of prior knowledge. There is no safety recall for the mechanical failure itself.
Common Symptoms
Loud engine knocking or a metallic banging sound
Reduced Engine Power message on the driver information center
Sudden loss of power and stall while driving
Engine seizes and will not restart
Oil pressure warning shortly before failure
How to Fix
There is no recall remedy. A failed engine is replaced, and under the 5-year/60,000-mile GM powertrain warranty this is covered at no cost - insist on the powertrain claim rather than accepting a goodwill quote. Before failure, the only mitigations are strict dexos1 Gen 3 oil adherence, shortened oil-change intervals (GM's oil-life monitor runs long for a small turbo engine), and never ignoring a knock or a Reduced Engine Power message - continuing to drive with a knock turns a bearing into a rod through the block. Owners with a failure outside warranty should document it against the pending class action and their state lemon-law statute.
On the 2024-2026 Buick Envista, a large and continuing cluster of NHTSA complaints describes the same blank-screen behavior as recall 23V744 on Envistas whose VINs are NOT in the recall population - including 2025 cars and 2024 cars built after the recall break point. Owners report both the cluster and the 11-inch infotainment display going black for 10-30 seconds at a time, repeated reboots, loss of audio and phone projection, and no stored trouble codes. Representative NHTSA complaints: ODI 11757017 (2024, telematics control module replaced, then repeated recurrences after two reprogramming attempts), ODI 11711372, and 2025-model complaints describing the screens dying and restarting throughout a drive. Dealer fixes escalate from radio reprogramming to a factory reset to replacement of the telematics control module, body control module or the cluster display itself, and several owners report the failure returning after each. GM's broader diagnostic guidance for blank GM screens points at software resets, LVDS display cable seating and radio-module testing before parts replacement.
Common Symptoms
Both the cluster and the center touchscreen go black for 10-30 seconds while driving
Infotainment screen repeatedly reboots
Touchscreen unresponsive
Audio and Apple CarPlay / Android Auto drop out with the screen
No diagnostic trouble codes found by the dealer
How to Fix
Confirm first whether the VIN is in recall 23V744 - if it is, take the free VCU software update. If it is not, the repair path under the 3-year/36,000-mile bumper-to-bumper warranty is: current radio and cluster software reprogramming, then a full infotainment factory reset, then inspection of the LVDS display ribbon connection, then replacement of the telematics control module or cluster display. Insist the dealer document each attempt - repeat unresolved failures of a safety-critical display are strong lemon-law evidence, and several owners needed three or more visits. Out of warranty a cluster display or TCM replacement is the expensive outcome.
