What are the most Common Problems and Solutions Of A Buick Encore?
What kind of issue does Buick Encore have? we will describe the most important issues that must be taken into consideration when you are in the market looking to buy a Buick Encore (BTW, it is made in South Korea). In the rest of the article, we will discuss every problem in detail. In addition, we will tell you how to identify it, solve it and how much it costs to fix. Interested? Keep reading!
The common issue of a Buick Encore is with the 1.4 gas engine due to the rough roar caused by excess air in the system and the reduced engine power due to a failed accelerator body. The turbo in 1.4L has many critical issues, the brakes make squeaking noises and the transmission can stammer.
Dashboard Chrome Trim Peeling
The older Buick with chrome panels around the middle console tends to be peeled off slowly. The newer models also have this problem, unfortunately. We have seen the problem even in the 2019 models. However, this is mainly a problem for Encore 2013-2016.
You have multiple options to make it look more suitable. The best restorative is to get an OEM replacement part if you want to keep your Encore looking better. Nevertheless, if you are okay with spraying or modifying, go ahead and do it.
After preparing the trim surface, you can spray it with chrome spray, making it more visible. Another way is to use a vinyl wrap – with so many choices of the vinyl wrapper, you can get any look you like.
Brakes tend to make a screeching noise when you use them. This is a kind of normal behaviour for old and worn brake pads. If the pads are new and still have the same noise, ask your dealer to give you the option kit. They will replace several parts, and noise must be greatly diminished.
This is also a problem that occurs in several encore models and not others. The dealer’s excuse is humidity; however, how they explain that some models have this issue while others do not!
(Engine Code 0171) Rough Idle And Wheezing Noise
This is a wellknown issue that happens a lot. There could be several reasons why you see this code. You need to check first the engine codes you will get from your scanner device.
You probably get engine codes 0172, 0131, 1101, and 0106. When the engine is running lean, it means excess air in the system. You might have a vacuum leak that leads to air access, making the system think your engine is running low on fuel.
The best way to check for the fault is to look for leaks around the intake manifold. Always inspect the areas that connect two hoses—these areas are more inclined to leak. You can inspect the valve cover or the front crank seal if there are no leaks. If you can’t find it, then check the following items.
- EVAP/Purge/canister solenoid
- Ignition coils
- Spark plugs
- MAF sensor
- Air filter
- Both O2 sensors
Oil Filter Can Be Confusing
With each model modification or facelift, some minor changes are made, and one of the changes includes the oil filter. You might replace the wrong oil filter, potentially causing extreme engine failure. You should always compare the original and the replacement side by side to assure that you replace the right filter.
You might be asking now, where it differs. — the 1.4L (LUV) uses the #55594651 while the 1.4L (LE2) uses the #12640445 oil filter supplied by GM. If you don’t know which engine type you have, go and check your VIN; if you have a “B” in the middle of your VIN, it means you have the LUV, and if your VIN has a letter “M” in the middle, then you have the LE2 type engine.
My Buick Encore Coolant Level Leaks
The coolant issue is very well-known on Buick Encore, and owners have complained a lot about the coolant level going down to about half every 5000-6000 miles or so. There have been reports that the dealerships can’t find an actual leak making it a pain to deal with.
Fortunately, there are items you can inspect and would probably help you to find the fault behind the coolant decrease. First, you need to check the area around the turbocharger, which tends to lose coolant. You won’t be able to find any drips under the vehicle as the coolant would evaporate after leaking under the hood.
If you still can’t find the leak after checking the turbo, go and ask your dealership to go for the dye test. You could see the area that loses the coolant with the polarized glasses that come with the kit. You can then find the leak with a black light under the polarized glass.
The fault often tends to be the coolant line that feeds the turbo—the area between the turbo and the engine. Luckily, the replacement hose wouldn’t be expensive; but the labour is, as the work is extensive.
You must remove the turbo to be able to replace the hose; the estimated cost is $600-$1000, so make sure to inspect that area properly if you are looking for a used spare part. As always, if you are looking to replace the hose outside of your dealership, you might get a deal and pay less than $500.
Reduced Engine Power With Check Engine Light And Stability Light
When the power is reduced along with the check engine light, the system tries to protect itself from a potential issue. This is a fairly common thing in Buick Encores. It is called the limp mode.
The dealerships might go with the throttle position sensor replacement or the ECM replacement. They might go with the accelerator pedal position if it doesn’t solve the problem.
However, the real culprit behind these problems is often the throttle body itself. You can clean it with a throttle body cleaner, and the problem should disappear. Sometimes you would have to replace the whole throttle body when cleaning doesn’t solve the problem. The throttle body replacement is going to cost about $300.
The infamous code that may cause PTSD. This is the kind of code that haunts the owners once it pops up. The standard protocol from every other GM/Buick dealership is to clear it and let the customer go. However, the right way is to replace the turbo, as simply resetting the system would never solve the problem.
If your Buick is under warranty, have the turbo replaced impromptu. If you don’t have a warranty, consider selling it as a new turbo would cost a fortune. If, however, you can find it used from a totaled vehicle, you can replace it with that. Note:— Chevy Trax is basically the same vehicle; it widens your options.
When buying a used Buick Encore, bring a scanner tool and see if it reads any code before and after driving a couple of blocks. If the scanner reads the code P0299, stay away from it—it will only cause you trouble. GM described a host of problems that could cause this fault code in their communication with dealers.
Turbos are always a pain to deal with—they can go south without warning, you might be carrying out all the required maintenance, and the turbo would still bail on you. If you are buying a high-mileage Buick Encore, you can see if the turbo has already been replaced; if it has been replaced—good; if not, consider another option.
Rear Differential Randomly Engage
If you are encountering this rear differential problem that would randomly engage—often making a popping sound, you need to address the rear differential fluid and the sensors involved. If the issue is unchecked, it could lead to irreparable damage, and you would have to resort to using AWD assembly.
There are plenty in the junk yards with totaled titles, and you can get the AWD assembly out of a low-mile Encore. Finding one with low miles with the rear intact shouldn’t be that hard as there are many with front-end damage. So you should be able to replace the whole AWD assembly and say goodbye to the issue.
The fluid replacement is going to cost you about $200-$300. If you have to replace the whole assembly—that is going to cost $500+
Transmission Stutters When Driving From Standstill
There have been several reports from Buick Encore owners that the vehicle would give you a slight jerk as if the gear engages when you put your foot on the gas. It wouldn’t do that when accelerating at a slow speed. The dealerships would say that it’s normal, while it only happens with every 6th or 7th Buick Encore out there.
From our research, the problem is likely related to the updated software. The same transmission is used in several other models under the GM, but none showed this behavior. If you can have your dealers install the software update of a Chevrolet Trax, you might get away with this stutter.
The software on the Encore tends to put the neutral every time it comes to a stop, and when it shifts into gear after you place your foot on the gas, you feel the thud. On the other hand, the Chevrolet Trax remains in gear even when you have come to a complete stop with your foot on the brake.
Overall, this problem is not considered a problem but rather an inconvenience or frustration, as some would say.
USB Won’t Work
This is one of the most common problems seen in Buick Encore. There have been numerous reports of the USB not working. The problem is that the Buick Encore electronics system is outdated, even in the 2020 models. The problem with these old systems is the inability to run 3.0 USB devices. The older 2.0, however, will work fine.
If you are running an old 2.0 and still the system won’t recognize the USB, try formatting the USB to FAT32 on your PC. The size shouldn’t be a problem as we have seen 128 GB USBs working just fine.
The Bluetooth Problem
If you are having issues with pairing your phone to the system, you can try removing it from the Encore and re-paring it anew; it should solve the issue. A similar pairing problem would cause you to have a problem making calls from your steering inputs, and repairing should solve the problem.
If you are having problems with the voice input while answering calls—you can hear their voice, but they can’t listen to yours; you are looking at a fuse problem. This problem is mainly caused by a malfunction in fuse #34 located under the dashboard. Replacing the fuse should solve this issue.
If you are unsure how to delete devices from the Buick Encore computer, remove any USB device currently connected to the system—Put the key on, turn it once, don’t crank, and turn it off. Open the door of the driver’s side for about 5 minutes—leave it open, don’t close it.
With these steps done, you will now be able to delete those old devices and pair them again without a problem.
Sound System Stuck On Voice Volume
This kind of problem happens due to the connectivity settings issue with your iPhone. Check your iPhone’s Bluetooth settings and click on the blue ‘I’ next to the Interlink. From ‘device type’, you can select car stereo—it should solve the problem.
Back-Up Camera Is Too Bright
It is a common concern, and it has been seen in several Buick Encores. The feature itself is pretty unique and is not available in most vehicles. You can adjust the brightness of these cameras. If your camera appears too light, you can adjust the brightness level, and this problem should be solved.
You can use the silver ring around the large dial to reduce the brightness. Put your Encore in reverse and push it in (hold), and you will see the magic happen.
