Across owner reports and automotive reviews, the most frequent trouble spots revolve around the transmission and powertrain, engine performance, and electrical/electronic systems. While many 2017 Terrains run well with proper maintenance, certain examples experience recurring issues that buyers should watch for.
Overview of frequent issues in the 2017 Terrain
Below are the areas where problems are most often cited by owners and regulators, along with guidance on symptoms and remedies. Each section signals what to monitor and how repairs are typically addressed.
Transmission and drivetrain problems
Owners frequently report issues related to shifting quality, hesitation, or rough transitions. In some cases, this progressed to transmission failure or error codes requiring service. These problems can manifest as delayed engagement or sudden shifts that feel harsh.
- Rough or delayed shifting and transmission shudder
- Transmission slipping or failure in some vehicles
- Check engine light or transmission-related diagnostic trouble codes
Notes: Transmission problems can be addressed with software updates, valve body or clutch replacements, or, in extreme cases, transmission rebuilds or replacement under warranty or recalls.
Engine performance and fuel economy
Some owners report oil consumption issues and occasional misfires or reduced power. There are sporadic reports of stalling or unexpected loss of power, particularly in higher-mileage or poorly maintained examples. Engine codes may point to misfires, oil-related concerns, or sensor failures.
- Oil consumption beyond expected levels between changes
- Engine misfires or reduced power with fault codes
- Occasional stalling or lack of acceleration
What to do: Maintain regular oil changes with the manufacturer’s recommended grade, monitor oil levels closely, and seek service if consumption seems high or power loss persists. Check for Technical Service Bulletins (TSBs) and ensure any open recalls or warranty actions are addressed.
Electrical systems and infotainment
The touchscreen, infotainment system, Bluetooth connectivity, and related dashboard electronics are occasionally troublesome, with reports of unresponsive displays, wireless dropouts, and sensor warnings triggered by glitches.
- Infotainment screen freezing or rebooting
- Bluetooth pairing failures or audio dropouts
- Sensor or warning light abnormalities without clear mechanical cause
In many cases, software updates or module replacements for the radio/navigation system resolve these issues.
Brake and steering issues
Braking and steering problems are less common but have appeared in some 2017 Terrains. Some drivers report unusual pedal feel or warning alerts, while others note intermittent loss of electric power steering assist in certain conditions.
- Brake pedal feel changes or ABS warning indicators
- Electric power steering (EPS) failure or reduced assist
- Stability control warnings or handling irregularities
What to do: Have braking and steering systems inspected by a qualified shop, verify there are no outstanding recalls, and ensure tires and alignment are up to date to maintain proper braking and handling performance.
Recall and safety-related issues
GM issued several recalls affecting SUVs around this era, and the 2017 Terrain is included in some campaigns. Recalls can cover fuel system components, braking systems, airbags, and related safety systems. Checking the vehicle’s VIN against recall databases is essential.
- Fuel system component recalls
- Airbag or sensor-related recalls
- Braking system or software recall campaigns
Action: If a recall exists, have the dealership perform repairs at no cost and verify recall status with the VIN and service history.
For buyers and owners: how to evaluate a 2017 Terrain
Before buying used or during ownership, use these steps to assess condition and minimize risk. A thorough check can help you avoid costly surprises down the line.
- Obtain complete service history and confirm all recalls and warranty actions are documented
- Have the transmission inspected if there are any shifting concerns or unusual noises
- Check for signs of excessive engine oil consumption and review maintenance records
- Run a diagnostic scan for fault codes and ensure infotainment software is up to date
- Verify VIN against NHTSA recall lists and check for any open safety campaigns
Pro tip: A well-documented maintenance history and an independent inspection can significantly reduce the risk of expensive repairs later.
Summary
The 2017 GMC Terrain presents a mix of commendable practicality and potential trouble spots. The most commonly reported problems center on transmission and drivetrain behavior, engine performance and oil usage, and electrical/infotainment glitches, with several recalls addressing safety-related items. Prospective buyers and current owners should review service and recall histories, stay attentive to unusual symptoms, and consult a qualified technician when in doubt. With attentive maintenance, many 2017 Terrains continue to serve as reliable daily drivers.
