2018 Buick Envision

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 Envision.

Body SUV

The 2018 Buick Envision is an SUV maintained with 6.0 quarts of 5W-30 engine oil, arriving in the model's third year on the market and following a 2017 model year that generated 80 owner complaints — the highest across the Envision's 2016–2026 history. With just 13 total complaints and zero recalls, the 2018 marks a sharp drop in reported issues, though suspension remains the top complaint area and warrants attention from anyone researching the vehicle. Against a complaint trajectory that would eventually reach a low of 7 by 2025, this model year sits in a transitional but solidly reliable period, meaning prospective buyers can approach it with reasonable confidence.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 7,500 mi; spark plugs every 97,500 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2016 and 2017 launch years for the Buick Envision were characterized by elevated federal scrutiny, peaking with 80 complaints and four recalls in 2017, but the generation's trajectory shifts favorably at the 2018 model year. In 2018, complaints plummeted to just 13, recalls dropped to zero, and technical service bulletins decreased to 852 from the previous year's 1045, marking a clear inflection point where early manufacturing instabilities were largely resolved. The data does not specify root causes for the 2018 model's few complaints, which are sparsely distributed across suspension, steering, unknown/other, and engine categories, alongside zero crash or fire incidents. Following 2018, the generation maintained a relatively stable and low complaint volume—typically between 10 and 23 annually—though minor recall activity briefly resurfaced in 2021. Positioned at the start of the model's mature, stabilized phase, the 2018 Envision is a demonstrably improved choice over the prior model years and represents a strong, reliable used buy.
