Cars today are packed with advanced features and systems, making them safer and more convenient. But more parts and technology also mean more things can go wrong. When problems happen, many resources are available to help drivers report and address these issues.
This article focuses on the 2020 GMC Terrain and the most common problems owners have shared. It also covers how lemon laws can help you if your vehicle turns out to be defective. Knowing your options can make dealing with a troublesome car less stressful.
Common Problems Reported by Owners
The 2020 GMC Terrain has received several complaints from owners about its performance and reliability. These issues range from minor annoyances to major safety concerns. Here are the most common problems:
Transmission Problems
Transmission problems can make it hard to control your vehicle. They can affect how smoothly you accelerate, decelerate, or even keep your car in gear. For the 2020 GMC Terrain, transmission issues are one of the most reported problems on the NHTSA website.
Drivers have mentioned gear slippage, where the car unexpectedly shifts between gears. Some report strange banging or scraping noises, while others have experienced total transmission failure, requiring a full replacement. Another common issue is the transmission not staying in a selected gear, especially in park, which can create serious safety risks.
In October 2020, a recall was issued for a problem with missing bolts on the start/stop accumulator’s endcap. This defect can cause transmission fluid to leak onto hot parts of the car, potentially starting a fire. The NHTSA Recall ID for this issue is 20V668000. There have also been a lot of class action lawsuits regarding the GMC transmission issues.
Brake Problems
Brake issues are some of the most serious problems a vehicle can have. When your brakes don’t work properly, it becomes harder or even impossible to stop when you need to. For the 2020 GMC Terrain, brake problems are among the most commonly reported issues on the National Highway Traffic Safety Administration (NHTSA) website.
Drivers have complained about brakes failing, requiring too much force to engage, or feeling weak. Some report the brakes locking up unexpectedly or the parking brake activating on its own without warning.
Fuel Efficiency Complaints
As stated on Consumer Reports, many 2020 GMC Terrain owners have reported that their fuel economy is worse than expected. The actual gas mileage often falls short of GMC’s estimates, leaving drivers frustrated, especially those who were counting on lower fuel costs.
Several factors could contribute to poor fuel efficiency. Common culprits include issues with sensors, like the oxygen (O₂) sensor, which helps manage the air-fuel ratio. If this sensor malfunctions, it can cause the engine to use more fuel than necessary. Problems with emission-control devices, like the exhaust gas recirculation (EGR) system, can also affect fuel economy by disrupting engine efficiency.
Other potential issues include faults in the fuel injection system, which delivers fuel to the engine, or the fuel pump, which provides the pressure needed for proper fuel flow. Some owners also report inaccurate readings from the fuel gauge or sender, making it harder to track fuel usage. Additionally, problems filling up the tank, such as slow refueling or pump shutoffs, have been noted.
Vehicle Speed Control Issues
Vehicle speed control includes features that help you manage your car’s speed, like cruise control. It’s not just about pressing the gas or brake but maintaining or adjusting speed smoothly.
In the 2020 GMC Terrain, many drivers have reported problems with the cruise control. One common issue is the cruise control shutting off suddenly without warning or any visible alert on the dashboard.
Infotainment System Glitches
Many 2020 GMC Terrain owners have reported problems with the infotainment system. The touchscreen often freezes or becomes unresponsive, making it difficult to use basic features. Some drivers also experience the system shutting down unexpectedly, forcing them to restart the car to regain access.
In addition to touchscreen issues, backup cameras, and navigation systems have been known to malfunction. The backup camera might show a blank screen or a delayed image, which can be a safety concern. The navigation system may display incorrect routes or fail to load entirely, leaving drivers frustrated.
Other reported glitches include problems with Bluetooth connectivity, which can make it hard to pair devices, and sound system failures, such as static or total audio loss. These issues disrupt the driving experience and can be particularly annoying during long trips.
Real Complaints from 2020 GMC Terrain Owners
Many owners of the 2020 GMC Terrain have shared their frustrations about persistent issues with the vehicle. These complaints often highlight recurring problems with critical systems, affecting reliability and safety. Here are some of the complaints:
- “I fell in love with this car as soon as we saw it. Unfortunately, it has been the worst vehicle I have ever owned. Frequent breakdowns resulted in weeks-long waits for parts. At 61k miles, the car started falling apart. Dash lights quit. The brake pedal broke. Cruise doesn’t work. The car is two years old and has cost almost $7,000 in repairs this year.”
- “Not long after I bought my 2020 GMC Terrain, my adaptive cruise started disengaging. There are never any warning lights, except the noise and vibration of the seat before it shuts off and tells you it’s disengaging. It’s now a regular occurrence. I’ve reported it to my dealership, but it never disengages when they drive it, so they say nothing is wrong. I have pictures and videos of the issue, and I’ve also noticed that my auto start/stop isn’t working anymore.”
- “This car spent roughly 39 days at the dealership for the same emissions problems within the first year of ownership. GMC played games until I hired an attorney. In May of 2019, they were forced to repurchase the vehicle under Wisconsin Lemon Law. Will NEVER purchase another GMC product!”
Legal Options for Your Unresolved GMC Terrain Issues in California
California’s lemon law protects you if your 2020 GMC Terrain has persistent defects. This law allows you to seek compensation or a replacement if your vehicle has a significant problem that the manufacturer or dealer can’t fix after a reasonable number of attempts.
If your Terrain is still under the manufacturer’s original warranty and the issue hasn’t been resolved despite multiple repair attempts, it might qualify as a lemon. Here’s how the process works:
Start with Repairs
When you notice a defect, take your Terrain to an authorized dealership for repairs. If the dealer fixes the problem, the process ends there. If not, keep bringing the car back and document each visit. Always save repair invoices, service records, and any communications with the dealer.
Understand What Counts as “Reasonable” Repair Attempts
In California, two to four repair attempts for the same issue are usually enough to qualify as reasonable. For serious safety defects, like brake failure or steering problems, fewer attempts may be required. If the vehicle spends over 30 days in the shop for repairs, it could also qualify as a lemon.
Request a Refund or Replacement
If your vehicle is a lemon, you can ask the manufacturer for a refund or a replacement. A refund covers the down payment, monthly payments, taxes, and fees. It may also include costs like towing or rental cars. A replacement vehicle must be of a similar make and model. The manufacturer can deduct a usage fee based on the miles you drove before the defect appeared.
Hire a Lemon Law Attorney
Manufacturers often have legal teams to fight lemon claims. Hiring a San Diego lemon law attorney ensures you have the right representation. An attorney will organize your paperwork, handle deadlines, and negotiate with the manufacturer. If the case goes to court, they will represent you.
No Out-of-Pocket Costs for Legal Help
In California, if you win your lemon law case, the manufacturer must pay your attorney’s fees and legal costs. This means pursuing a lemon law claim comes at no personal expense to you. You only stand to gain a resolution, whether it’s a refund or a replacement.
