2018 Chevrolet Traverse

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

Body SUVTransmission Automatic 9-spd

The 2018 Chevrolet Traverse is an SUV built on a front‑wheel‑drive platform. Its powertrain is paired with an automatic 9‑speed transmission and a 5.0‑quart oil capacity that calls for either 5W‑30 or 0W‑30 viscosity. EPA estimates put its fuel economy at 17 city, 25 highway and 20 combined miles per gallon. In terms of reliability, the 2018 model records 452 total owner complaints, a figure that sits well below the 668 complaints peak of 2010 yet remains higher than the 18 complaints logged in the latest 2026 year, reflecting a moderate standing in the model’s complaint history.

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 2018 model year registers 452 complaints, marking a significant increase from 358 in 2017 and exceeding 398 in 2019, yet it carries only 2 recalls—fewer than the 3 recorded for both adjacent years and representing a generational low in safety campaigns. Across the Traverse’s production run, federal data reveals a trajectory of declining regulatory activity from the high-volume early years (2009-2011 saw 448-668 annual complaints and 5-8 recalls), with 2018 falling within a late-generation uptick in owner-reported issues despite minimal formal recalls. Technical Service Bulletins also rose slightly to 1,106 from 1,000 in 2017, though remaining well below the generation’s peak of 1,669 in 2013. Power Train concerns dominate the 2018 docket with 114 filings, though the data does not specify root causes, alongside modest crash (9) and fire (2) incident reports. Given the elevated complaint volume relative to surrounding years but historically low recall exposure, 2018 represents a moderate-risk purchase that warrants thorough pre-buy inspection of powertrain and electrical systems.
