1. Valve cover gaskets been replaced in valve covers been replaced twice. 04/16/2024. 95113 miles 2. Air conditioning cooling leak and the fan motor would not shut off unless disconnecting the battery cable. 08/26/2024 at 100,254 miles 3. The turbocharger inline for the oil intake has been replaced. The car cannot completely carry a full carload without having no power to get up hills. I have no power once in a while if I'm alone driving just on a straight road or going uphills it seems like there's no gas getting to it I have good gas but it doesn't happen all the time. And I guess to where it will slow down from 55 to 35 pushing on the gas pedal with no power at all and then all the sudden it will go. Trying to explain this the best I can. 09/29/2024 at 101, 313 miles

Turbo replaced under recall in March 2024 at local GMC dealership. June 2024 oil changed at independent service center and was informed that oil leak from turbo present. Vehicle brought back to dealership in June 2024 where vehicle was repaired for oil feed line being loose at the feed line. July 2024 car taken to independent mechanic and informed that a new turbo is needed. If turbo problem persists it will result in the vehicle shutting down while driving, violent shaking of the engine, and acceleration issues that could result in full engine failure if not resolved. The repairs done for the recall has not rectified the faulty turbo problem. The faulty turbos originally installed and being used for replacements are a safety hazard for any Buick Encore driver.

My check engine light came on in February 2024, vehicle mileage at the time was approximately 70,000 miles. My certified GM independent mechanic's diagnostic check revealed a DTC-P0299 code: faulty turbo charger. He advised repairs be made at a GM dealer under Special Coverage N-232395330 released in February 2024 by GM. My GM dealer (where I purchaser the vehicle) has also received the P0299 code and advised replacing the turbo charger. But since my VIN number is not a part of the Special Coverage, the cost of repairs would be my responsibility. I am requesting my vehicle's VIN be added to the Special Coverage and GM provide me the appropriate customer letter to cover all costs related my repair work.

There is a known defect with the GM Ecotec engines, specifically the lack of retaining clip for the internal PCV valve, allowing it to become dislodged and drawn into the engine. Without the PCV valve, tremendous engine pressure is produced, leading to broken gaskets causing vacuum leaks, misfiring, severe vibration, and loss of power when accelerating (which can be a safety issue). Dorman produced a video outlining the issue and has re-engineered the part to prevent the issue from occurring: "Why GM 1.4L Ecotec engine intake manifold and valve covers repairs are often related" [XXX] This appears to be a fairly wide-spread issue with the GM Ecotec engines, and GM should perform a recall to replace these parts, and reimburse those who had to replace themselves. This also causes error codes requiring spark plugs to be replaced (they get fouled by oil) and the MAF Sensor. In troubleshooting, I also had to replace the distributor power bar and air intake hose. I have recipts for all parts, but file upload is not working on this site. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Back in July 2022 I started receiving error messages of the stabilitrak system to get checked by OnStar. I took to Ed Martin Buick in Carmel, In they thought that it was from possibly pressing brake and pedal at same time and fixed code. Then about two weeks later I got the same error code, I took to Ray Skillman Northeast Buick they said it was a transmission manufacturing defect and had to do with Manifold which they fixed under power train warranty. Now February 2023 I have same issue Stabilitrak error message. I have to take back again to Ray Skillman Northeast Buick. This is an ongoing issue and should not be receiving same codes car only has 67,000 miles and should not be having transmission issues either.

Bought a 2017 Buick Encore November 2020 less than 6 months into owning the car check engine light came on. Purge solenoid as well as the Camshaft and 1 other component had a leak brought it to dealership and it was covered under warranty for repairs. Fast forward about a year and a half there is another leak will be bringing back to dealership and paying out of pocket for leaks because of a rough idle, poor fuel economy, and another check engine light problem. Have also read articles about this particular cars not fairing well in the temperatures changes during the seasonal changes. Yet there is no recalls and no mention of Buick or GMC being held responsible for this recurring problem.

Vehicle check engine light (illuminated amber picture of an engine) came on. Vehicle started running rough. Difficulty keeping the vehicle running at idle. Engine running rough/poor acceleration. Drove vehicle to local service center and left for diagnosis and repair. Service center scanned computer for codes. Found the P.C.V. vacuum control in the valve cover had torn its diaphragm and the engine was running with 19" of vacuum in it, where it is normally at 2"- 3" of vacuum. Service center obtained and installed new dealer valve cover assembly with P.C.V. control valve and gasket. Service center said they have repaired three-four of these in past few weeks. Service center said recall may be forthcoming. Have documentation.

Vehicle has been in and out of shop since Feb 2022 for 'limp mode' disabled due to faulty booster or something. Vehicles leave driver stranded unable to accelerate or maneuver vehicle to avoid a collision. I'm told this is a well known problem for both this vehicle and the chevy cruze although no recalls are out for this huge safety issue. Somebody is seriously going to get injured if driver is unable to move car to safety when it just dies on the highway or road. All documentation is available for the excessive repairs that don't resolve the issue the correction only last from 24 hours to 2 weeks before the light comes on again and car dies.

Started stalling at idle, then just shuttered and stalled while moving, 28882.moles. Had crank, air would run but would not restart. Dealer had it for a week and told me was battery. Weird because it had crank but wouldnt start. Had it back and immediately notice did not accelerate right, very hesitant and at idle nearly stalled, felt like was "missing". a few days later it stalled twice while at a stop light on busy street right in front of dealership! it stalled again 2 days later so back to dealership. No codes of course. They said drove it for miles and couldn't duplicate. They actually drove it for 9 miles! gave me loaner and will keep it over weekend. Afraid someone is gonna run into back at a light when it stalls. Something is wrong and noone can figure it out.

My 2017 Encore burst into flames. I arrived to work after lunch, I parked and turned off the ignition and I see smoke coming from under the hood of my car. I paused just a moment to see if it was going to stop but it got worse very fast. I grabbed my purse and jumped out of the car as the front end closest to the windshield was becoming engulfed in flames. I immediately called 911 but by the time the fire department arrived, it was too late to save the car.

This vehicle had less than 8,000 miles on it and had only been serviced one time by the dealer (oil change in May 2018) the engine caught on fire and consumed the entire front end of the vehicle. The driver was in the drive through lane of a kfc restaurant when the car caught on fire. 03 my 89 year old mother-in-law was dragged from the car to safety by 2 bystanders but could have very easily been killed. Have there been engine fire issues with this vehicle? a car with low miles that was serviced by the dealer should not spontaneously erupt into a fireball.
