If you experience any ESC-related problems, it is important to have your GMC Terrain inspected by a qualified mechanic.
Known Performance Problems
When it comes to the GMC Terrain, there are a few performance issues that have been reported by owners. These problems can range from minor inconveniences to more serious concerns. In this section, we will take a closer look at some of the known that you may encounter with your GMC Terrain.
Poor Fuel Efficiency
One of the common complaints among GMC Terrain owners is poor fuel efficiency. Many owners have reported that their Terrain consumes more fuel than expected, leading to frequent trips to the gas station. This can be particularly frustrating for those who purchased the Terrain with the expectation of better fuel economy.
There can be several factors contributing to this issue. One possibility is that the engine is not running efficiently, causing it to burn more fuel than necessary. Another factor could be the vehicle’s weight and aerodynamics, which can impact its fuel efficiency. Additionally, driving habits such as frequent acceleration and braking can also contribute to poor fuel economy.
If you are experiencing poor fuel efficiency with your GMC Terrain, there are a few steps you can take to improve it. First, make sure that your tires are properly inflated, as underinflated tires can increase fuel consumption. Additionally, try to avoid aggressive driving and maintain a steady speed whenever possible. Regular maintenance, such as oil changes and air filter replacements, can also help optimize fuel efficiency.
Engine Stalling
Engine stalling is another performance problem that some GMC Terrain owners have encountered. This can happen unexpectedly, leaving the driver stranded and unable to continue their journey. Engine stalling can occur for a variety of reasons, and it’s important to identify the underlying cause to prevent future occurrences.
One possible cause of engine stalling in the GMC Terrain is a faulty ignition switch. The ignition switch is responsible for providing power to the vehicle’s electrical system, including the engine. If the switch is malfunctioning, it can disrupt the flow of power and cause the engine to stall.
Another potential cause of engine stalling is a clogged fuel filter. Over time, dirt and debris can accumulate in the fuel filter, restricting the flow of fuel to the engine. This can result in engine hesitation or stalling.
If you are experiencing engine stalling with your GMC Terrain, it is recommended to have it inspected by a qualified mechanic. They will be able to diagnose the issue and determine the appropriate course of action. This may involve replacing the ignition switch or cleaning/replacing the fuel filter.
Excessive Oil Consumption
Excessive oil consumption is a performance problem that has been reported by some GMC Terrain owners. This issue can be concerning as it may indicate an underlying problem with the engine or other components.
There can be several reasons why a GMC Terrain may consume excessive amounts of oil. One possibility is worn piston rings or valve seals, which can allow oil to leak into the combustion chamber and be burned off during the combustion process. Another potential cause could be a leak in the engine’s oil seals or gaskets, resulting in oil loss.
Excessive oil consumption can lead to engine damage if not addressed promptly. It is important to regularly check your oil levels and top up if necessary. If you notice that your Terrain is consistently using more oil than usual, it is recommended to have it inspected by a professional. They will be able to identify the cause of the excessive oil consumption and recommend the appropriate repairs.
Rough Shifting
Some GMC Terrain owners have reported experiencing rough shifting when driving their vehicles. This can manifest as jerky or delayed gear changes, making for an uncomfortable driving experience.
There can be a few reasons why your Terrain may have rough shifting. One possibility is a problem with the transmission fluid. Low or dirty transmission fluid can affect the smooth operation of the transmission, leading to rough shifting. Another potential cause could be a worn clutch or pressure plate, which can cause the gears to engage improperly.
If you are experiencing rough shifting with your GMC Terrain, it is recommended to have the transmission fluid checked and replaced if necessary. Additionally, a qualified mechanic should inspect the clutch and pressure plate to determine if they need to be replaced.
Unresponsive Acceleration
Unresponsive acceleration is another performance issue that some GMC Terrain owners have encountered. This can be particularly frustrating when trying to merge onto a highway or pass another vehicle.
There can be a few factors contributing to unresponsive acceleration in the GMC Terrain. One possibility is a problem with the throttle body. The throttle body is responsible for regulating the amount of air entering the engine, which affects acceleration. If the throttle body is dirty or malfunctioning, it can result in unresponsive acceleration.
Another potential cause of unresponsive acceleration is a clogged fuel injector. Over time, fuel injectors can become clogged with dirt and debris, reducing their ability to deliver fuel to the engine efficiently. This can lead to sluggish acceleration.
If you are experiencing unresponsive acceleration with your GMC Terrain, it is recommended to have the throttle body and fuel injectors inspected and cleaned if necessary. This can help restore proper engine performance and improve acceleration.
Consumer Complaints and Reviews
Defective Engine Components
When it comes to consumer complaints and reviews about the GMC Terrain, one common issue that has been reported is defective engine components. Many owners have experienced problems with their engine, ranging from minor issues to major failures.

Another issue that has been reported is brake squealing or grinding noises. Some owners have mentioned that their Terrain’s brakes make high-pitched squealing sounds or grinding noises when applied. These noises can be a sign of worn brake pads or other brake system components, and if left unaddressed, they can lead to further damage and compromised braking performance.
Additionally, some Terrain owners have experienced problems with the vehicle’s brake pedal feel. Complaints range from a soft or spongy brake pedal to a hard or unresponsive pedal. These issues can make it difficult for owners to modulate the braking force effectively, potentially compromising their ability to stop the vehicle safely.
Steering and Suspension Problems Experienced by Owners
Steering and suspension problems have also been reported by GMC Terrain owners, with various complaints highlighting issues related to the vehicle’s steering responsiveness and stability.
One common complaint is steering wheel vibrations. Some Terrain owners have noticed that their steering wheel vibrates or shakes while driving, particularly at higher speeds. This can be a sign of unbalanced wheels or worn-out suspension components, which can affect the overall driving experience and potentially compromise the vehicle’s safety.
Another issue that has been reported is a loose or wandering steering feel. Some owners have mentioned that their Terrain’s steering feels loose or imprecise, making it difficult to maintain a straight line or navigate through curves. This can be a cause for concern, as it can affect the vehicle’s stability and control, especially during emergency maneuvers or adverse driving conditions.
Additionally, some Terrain owners have experienced problems with the vehicle’s suspension system. Complaints range from excessive body roll during cornering to a harsh and uncomfortable ride quality. These issues can not only affect the comfort of the occupants but also impact the vehicle’s handling and stability.
In conclusion, consumer complaints and reviews about the GMC Terrain have highlighted various issues with the vehicle’s engine components, transmission, electrical system, brake system, and steering and suspension. From defective engine components and transmission failures to electrical malfunctions and brake system issues, these problems can significantly impact the vehicle’s reliability, safety, and overall performance.
