Specific Mechanical and Engine Problems
Under The Hood: 2018 GMC Terrain’s Engine Challenges
The 2018 GMC Terrain has had some reported issues under the hood. Key among them is the engine, some customers have experienced stalling or total shut down while the vehicle was in operation. This problem is not just a significant inconvenience but, importantly, a serious safety hazard. A stalling engine can potentially result in accidents or collisions.
These engine difficulties are largely traced back to the vehicle’s fuel pump system. Problems arise when it delivers an inadequate pressure output or fails altogether, causing the engine to lack sufficient fuel needed for peak performance. This kind of fuel pump issue could be a reason behind the occasional engine shutdowns and subsequent stalling.
Another noteworthy issue associated with the 2018 GMC Terrain is the engine consuming more oil than expected. This quirk leads to frequent necessary top-ups before the standard maintenance schedule demands. If not addressed, this excessive oil consumption might prematurely wear down the engine parts and subsequently result in notable repair costs in the future.
Transmission Problems in 2018 GMC Terrain
The Terrain is also plagued with transmission problems. The most common of these are a lack of response from the automatic gearbox and unexpected shifting of gears. A lag in transmission response could pose a significant issue – particularly while trying to overtake other vehicles on the highway or wanting a sudden acceleration.
Meanwhile, the sudden shifting of gears can lead to jerks or the vehicle shifting into a lower gear unexpectedly. It might decelerate suddenly, posing a danger to the vehicle occupants and other road users. These transmission problems can also lead to undue wear and tear on the vehicle, resulting in more frequent and costly repairs or replacements.
Infotainment System Malfunctions
Customers also note infotainment system malfunctions where it refuses to start up, freezes intermittently, or completely shuts down without any warning. The failure of the entertainment system negates part of the driving experience, causing dissatisfaction among users.
The battery of the GMC Terrain 2018 has also been reported to drain quickly in some cases. Fast battery drainage can affect various aspects of the vehicle, from engine starts to electronic systems performance.
The 2018 GMC Terrain, though boasting appealing aesthetics and numerous features, has also unfortunately been subject to a number of mechanical and reliability issues. These problems have led to a significant degree of dissatisfaction among consumers. Here we highlight some of the most commonly reported issues, though it’s important to note that this is not an exhaustive enumeration.

Information on Recalls and Service Bulletins
As of the present day, three recalls that directly pertain to the 2018 GMC Terrain have been officially issued.
The inaugural recall, announced in June of 2018, focused on a potential software flaw which could disable the airbags and seatbelt pre-tensioners during a collision, thereby dramatically increasing the potential for injury to the vehicle’s occupants. In response to this threat, GMC offered a free of charge software update to resolve the problem.
In October of the same year, a second recall was issued relating to a potential problem with the flange of the high pressure fuel pump. This could possibly crack and cause a fuel leak. To address this issue, GMC offered to replace the affected fuel pump and pipe, also free of charge.
The third and most recent recall, made public in August 2020, highlights a problem with a sensing diagnostic module (SDM). This SDM may not consistently switch off when the vehicle is turned off, which could lead to battery drainage. In response, GMC offered a reprogramming of the SDM to include a power-down feature when the vehicle is switched off.

Consumer Reviews and Opinions
Detailed Look at the 2018 GMC Terrain
The 2018 GMC Terrain, a compact crossover SUV, has gained quite a reputation within the GMC community due to its imposing style, exceptional performance, and lavish interior. Consumers and car critics have praised this model extensively. However, the model suffers from a downside, as several owners have reported issues that have impacted their overall satisfaction and the vehicle’s performance. Therefore, while considering this vehicle, users should be aware of these potential issues.
Engine and Transmission Problems
One common issue highlighted by consumers is related to the 2018 GMC Terrain’s engine and transmission. Some owners reported experiencing hesitation or a jerking motion when trying to accelerate. A possible cause for this could be issues with the vehicle’s nine-speed automatic transmission, leading to performance inconsistencies.

Infotainment System
Many users have reported encountering problems with the Terrain’s GMC infotainment system. These software glitches could lead to the navigation, radio, or Bluetooth functions malfunctioning. Some users also mentioned that the display screen sometimes goes blank, freezes, or reboots while driving.
Comfort and Quality Issues
While the 2018 GMC Terrain has been applauded for its comfort and quality, making a good impression with its high-quality interior materials and soundproofing, some consumers noted problems in this area. Noise was a particular concern for some, both in terms of wind noise at higher speeds and engine noise at lower speeds. These complaints could suggest that the soundproofing measures may not be entirely effective across the range of driving conditions.
Exterior and Interior Problems
If we take a closer look, the interior and exterior of the 2018 GMC Terrain aren’t exempt from criticism either. Some owners claimed that they experienced manifestations like peeling paint, weak door seals, and rattling coil springs. On the inside, certain users reported degraded upholstery, malfunctioning seat heaters, and faulty instrument panels which could indicate a lack of attention to finer details in the design process.
Safety System Concerns
GMC’s safety systems, while generally reliable, have led to reports of occasional faults in the 2018 Terrain. Some of these safety issues included instances where certain sensors detected crashes inaccurately or where the emergency braking system activated unexpectedly. In some instances, the backup camera failed to display an image, leading to potential safety hazards.
Consumer Experience: The Final Take
Even though these issues seem worrisome, it’s important to remember that not all 2018 GMC Terrains will have these problems, and they don’t represent a universal experience. For many, the 2018 GMC Terrain emerges as a reliable, capable, and stylish compact SUV. However, prospective buyers should be aware of these potential faults and look out for them when making a purchasing decision.
In retrospect, the 2018 GMC Terrain’s profile, like many others in its category, is a mix of praise and critique. Owners commend the compact SUV for its bevy of features, spaciousness and overall good looks. Conversely, concerns around specific mechanical and engine troubles have also surfaced, acting as a notable counterpoint to the overall acceptance of the vehicle. The manufacturer’s response, as underscored by the released recalls and service bulletins, indicates a level of accountability. However, the lasting impression of a car is often not painted with a broad brush but rather depends on individual micro-experiences. Having looked at these, we hope this information enables you to make more informed decisions or add to your automotive knowledge base.
