2007 GMC Acadia: The Troubled Beginning
The GMC Acadia made its debut in 2007, and while it was well-received for its sleek design and spacious interior, the first model year had its fair share of problems. As with many debut models, the 2007 Acadia faced growing pains. Early owners reported several significant issues that would affect the vehicle’s reliability and longevity.
Transmission Issues: One of the most significant complaints about the 2007 GMC Acadia revolves around transmission problems. Many owners reported delayed shifting, rough gear transitions, and sudden slipping of the transmission. These issues often led to costly repairs, with some owners paying thousands of dollars to replace the transmission entirely.
Engine Problems: Another issue that plagued the 2007 Acadia was engine-related problems. Some vehicles experienced engine misfires, rough idling, and even complete engine failure. These issues were often caused by defective fuel injectors or ignition coils, which would need replacing to restore proper engine function.
Air Conditioning Failures: Several 2007 Acadia owners complained about the vehicle’s air conditioning system. The AC would often stop working altogether, or only provide minimal cooling. In some cases, the air conditioning evaporator would fail, requiring a full replacement of the unit.
While the 2007 Acadia is a solid vehicle in many respects, these early reliability concerns make it a year to avoid if you’re in the market for a used GMC Acadia.
2008 GMC Acadia: A Year of Even More Trouble
Following the 2007 model, the 2008 GMC Acadia continued to face many of the same problems but introduced a new set of issues that made it even more problematic.
Transmission Failures: While the 2008 model addressed some transmission concerns, it still suffered from high rates of failure. Many owners reported experiencing rough shifting, delayed gear changes, and even complete transmission failure. This problem typically appeared around the 75,000-mile mark, often resulting in repair bills ranging from $3,500 to $4,000.
Steering Problems: The 2008 GMC Acadia also had a number of steering-related issues. Some vehicles experienced difficulty in steering, particularly when driving at low speeds or making sharp turns. This issue was typically linked to the power steering pump or the steering rack, both of which were expensive to replace.
Electrical System Malfunctions: Another frequent problem with the 2008 Acadia was issues with its electrical system. This included faulty door locks, malfunctioning windows, and a range of problems with the vehicle’s lighting system. Owners also reported frequent warning lights flashing on the dashboard, even when no mechanical issues were present.
Overall, the 2008 GMC Acadia does not represent a significant improvement over the 2007 model, and many of the same problems persisted. If you’re looking for a reliable used vehicle, this year should likely be avoided.
2012 and 2013 GMC Acadia: A Return to Engine Issues
After a few years of improvement, the 2012 and 2013 GMC Acadia models saw a resurgence of serious engine issues that marred their reliability.
Engine Coolant Leaks: One of the most reported problems with the 2012 and 2013 Acadia models was coolant leaks. These leaks were often traced back to faulty intake manifold gaskets, which would cause coolant to leak into the engine, potentially leading to overheating and engine damage. The repair cost for this issue could be upwards of $1,000 to $1,500, depending on the severity of the leak.
Timing Chain Problems: Timing chain problems also became common in the 2012 and 2013 Acadia. The timing chain is a critical component of the engine, and if it wears out or breaks, it can cause severe engine damage. Many owners reported hearing rattling noises from the engine, which is often a sign of a failing timing chain.
Transmission Problems: While not as widespread as in earlier models, the 2012 and 2013 Acadia still experienced transmission issues. Some drivers reported slipping gears, hesitation during acceleration, and harsh shifting. These problems often required expensive repairs or even transmission replacement, which can cost between $3,000 and $4,500.
While the 2012 and 2013 GMC Acadia models might look appealing with their more modern features, the persistent engine and transmission problems make these years less than ideal for used car buyers.
2017 and 2018 GMC Acadia: New Generation, New Problems
In 2017, GMC introduced the second generation of the Acadia, which featured a new design and updated features. While the updated model addressed some of the older vehicle’s issues, it also introduced new problems, particularly concerning safety features and mechanical components.
Drivetrain Issues: One of the most significant problems with the 2017 and 2018 Acadia was issues with the drivetrain. In some cases, the driveshaft would detach while driving or idling, potentially causing accidents or leaving the vehicle immobile. This problem was particularly prevalent in the 2017 model but was also reported in the 2018 Acadia. A driveshaft replacement could cost upwards of $1,500 to $2,000.
Safety Feature Failures: These model years also had a number of complaints about their safety features. Problems included malfunctioning seatbelt sensors, airbags that failed to deploy in the event of an accident, and issues with the rearview camera system. These failures can be particularly concerning for potential buyers who prioritize vehicle safety.
Fuel Pump Leaks: Another common issue with the 2017 and 2018 GMC Acadia models was fuel pump leaks. Leaking fuel pumps can pose significant safety hazards and lead to costly repairs. In some cases, owners reported a strong fuel smell inside the cabin, which indicated a leak in the fuel system.
While the 2017 and 2018 models offered a more modern design and improved technology, these new problems made them less reliable than their predecessors.
Common Problems Across Multiple Years
Several problems have plagued GMC Acadia models across various years, including transmission issues, engine problems, and air conditioning failures. These recurring issues are worth considering when evaluating a used Acadia.
Transmission Problems: Transmission failures have been a long-standing issue for several GMC Acadia model years, especially in the earlier years. Slipping gears, delayed shifts, and sudden transmission failure can be costly to repair and can compromise the vehicle’s safety.
Engine Problems: Engine issues, such as coolant leaks, oil leaks, and failing ignition coils, have been common across many model years. These problems can lead to engine overheating, misfires, and even total engine failure.
Air Conditioning Failures: Air conditioning problems, particularly with evaporator leaks, have been a recurrent issue across many GMC Acadia model years. This problem often leads to poor cooling performance and expensive repairs.
