Does the 2018 Traverse have transmission problems?

Yes. Some 2018 Chevrolet Traverse models have reported transmission problems, particularly with the new nine-speed automatic introduced for that year. The issue is not universal, but a notable subset of owners have described symptoms such as rough shifting, hesitation, and occasional shudder. This article examines what has been reported, what official guidance exists, and what potential buyers can do to assess risk.


Scope of the issue and common symptoms


Overview


The 2018 Traverse marked a departure from earlier models by introducing a more complex nine-speed automatic transmission. While many owners have reported smooth performance, there is a documented pattern of transmission-related complaints affecting a portion of units. The prevalence appears to vary by production date, maintenance history, and driving conditions.


Below are the symptoms most often cited by owners and independent testers. Before delving into the list, note that experiencing one or two of these signs does not automatically mean the transmission is failing, but it does warrant a dealer inspection.



  • Rough or delayed shifting between gears, especially when moving from idle to drive or when accelerating from a stop.

  • Transmission slipping or hesitation during acceleration, causing the vehicle to feel underpowered.

  • Shuddering or clunking sensations at low speeds or during light throttle

  • Warning lights such as the Check Engine light or a transmission-related warning on the dashboard

  • In rare cases, complete transmission failure or a failure to move in gear


The pattern of reports suggests variability in how the issue manifests, with some owners experiencing no problems for many miles and others encountering symptoms sooner in the vehicle’s life. Shifting behavior may be most noticeable in certain driving conditions, such as stop-and-go traffic or cold starts.


Recalls, service campaigns and official guidance


What GM and regulators have done


There have been recalls and service campaigns linked to the 2018 Traverse’s transmission in some markets. While not every vehicle is affected, owners should check their VIN against official recall databases and consult Chevrolet for guidance on software updates or hardware replacements that may apply to their car. In some cases, dealers have performed software updates, reprogramming, or component replacements as part of warranty service campaigns.


To determine whether a specific 2018 Traverse is under any active recall or service campaign, consumers should reference the NHTSA recall portal or Chevrolet’s official recall lookup using the vehicle’s VIN. It is important to verify coverage because recall status and warranty accommodations can vary by production date and region.


Conversations with automotive reporters and consumer advocacy groups indicate that while there have been remediation efforts, not all affected vehicles see a fix, and some owners report ongoing concerns despite service visits. The takeaway is to check VIN-specific information and pursue dealer diagnostics if symptoms appear.


What to do if you own or are considering buying a 2018 Traverse


For owners, buyers, and prospective purchasers, practical steps can help manage risk and ensure proper care if transmission symptoms appear. The following guidance is intended to be actionable and VIN-specific where possible.


Before this list, note that the recommendations below are intended to inform, not replace professional evaluation. Always consult a certified Chevrolet technician for a formal diagnosis.



  • Check for active recalls or service campaigns on your VIN using NHTSA’s recall database or Chevrolet’s recall lookup. If any apply, schedule the work promptly at an authorized dealer.

  • Document symptoms with dates, driving conditions, and any corresponding codes or dash lights. This helps the technician reproduce the issue and accelerates diagnosis.

  • Ask the dealer to review any available service bulletins or software updates for the 9-speed transmission. A reflash or calibration change can resolve certain shifting problems.

  • Request a comprehensive transmission diagnosis, including fluid condition, sensor readings, and any fault codes. If the fluid appears degraded or dark, discuss proper service or replacement recommendations.

  • Clarify warranty coverage with the dealership. Depending on age, mileage, and recall status, certain transmission issues may qualify for warranty repair or an extended service campaign.

  • Keep up with regular maintenance, including transmission fluid checks (or changes if specified by GM) and other recommended service intervals to minimize wear-related problems.


For buyers evaluating a used 2018 Traverse, comprehensive due diligence is advised. Obtain a full vehicle history, review maintenance records, and insist on a pre-purchase inspection that includes a transmission assessment. A test drive that intentionally exercises a range of speeds and gears can help surface shifting irregularities before purchase.


Bottom line and guidance for prospective buyers


The 2018 Chevrolet Traverse can be a solid family SUV, but the transmission has been a point of concern for a subset of owners. The issue is not universal, and GM has undertaken recalls and service actions to address reported problems in some vehicles. As with any used vehicle, VIN-specific information, service history, and recent updates matter a great deal in determining risk. Prospective buyers should prioritize VIN-based recall checks, confirmed software updates, and a thorough diagnostic if any shifting issues are observed during a test drive.


Summary


In brief, the 2018 Traverse has experienced transmission-related complaints from some owners, chiefly involving the nine-speed automatic. While not every vehicle is affected, complaints have prompted recalls and service campaigns in certain cases, and dealers may offer software updates or component repairs under warranty. For current owners, proactive maintenance and prompt dealer consultation when symptoms appear are advisable; for potential buyers, VIN-specific recall status and a thorough transmission diagnostic are essential steps before purchase. As always, verify the latest official guidance from GM and NHTSA for the most accurate, up-to-date information.
