36 Engine And Engine Cooling problem of the 2017 Buick Encore

Failure Date: 03/21/2025

The turbo charge is not providing adequate power. I was on the highway and the car began to chugging then accelerated on its own and all the lights on the dash came on then all went off like it was going to shut down. I put my hazards on and started to pull to the side of the highway. I gave it a moment for the car and for me because I was terrified, my kids were in the car and traffic was going steady around 70-75 miles per hour and I was scared as it began to shut down that I would be hit by traffic behind me before I could get over. It started driving again. It still drives but is hard to accelerate and even when stopped you can see the rpm rising. It’s as if the car never idles, it feels as though is constantly under load. I have had it looked at professionally at midas but they will only say they think it is the turbo as there are no codes coming up. I have had it looked at by mechanics I know who have fixed other things that may cause similar issues and nothing has worked and they also believe it is the turbo. I’ve know other people with Buicks and they have had similar problems I’m confused as to why this 1. 4 liter turbo has not been recalled.

42 Engine And Engine Cooling problem of the 2016 Buick Encore

Failure Date: 02/01/2025

My wife is [xxx] and I am [xxx] old. We purchased the 2016 Buick Encore with 29,000 miles from Buick GMC of beaverton, oregon on [xxx], expecting that it would out last both of us, since we are retired and only drive to the store and doctor's appointments; my wife has miraculously survived stage iv cancer since February 1, 2019. The Encore is our only car and we depend on it for all transportation. We love the vehicle, changed the oil about every 3,000 miles, and have had no complaints for almost six years. On [xxx], my wife and I were driving home from shopping, in rain at night on [xxx] north bound, left lane, uphill at 55mph in moderate traffic on a six-lane divided freeway. Suddenly the car lost half power, began missing and shaking badly, speed dropped to about 30 mph with cars serving behind us, flying past us honking. We were panicked, not knowing if the car would seize up completely or the engine would explode. Fortunately, we limped off the highway without having to stop. We took the car back to the dealership where we bought it, for service. The next day they emailed a video of their inspection of the vehicle showing cylinder 1 has very low compression of about 60 when normal should be 180 to 210 psi, which indicates a likely blown piston. April 30, 2019, NHTSA service bulletin 19-na-090 describes the identical symptoms the Encore is experiencing: misfire and low compression in one or more cylinders. Both the Buick GMC of beaverton dealership and general motors, 800-521-7300 are refusing to honor the original 70k mile warranty since they're indicating the warranty expired on 01/21/2023. We are devastated that because we pampered the vehicle and only drove it 17,000 miles in nearly 6 years, we are being unfairly penalized. Gm admits that if we had driven the vehicle more and this same engine failure occurred at just 49k miles prior to January 20, 2023, they would immediately replace the engine. Help! we are requesting that NHTSA information redacted pursuant to the freedom of information act.

This is an addendum to complaint # 11644925 before taking the car back to the dealership, Buick GMC of beaverton, for repairs, I called the owner of bassitt auto repair in beaverton oregon, 503-616-2007. He told me that they've had 3 other Buick Encores come to his repair shop in just the last 6 months, all with the identical problem. He said, without seeing our vehicle, that it is low compression due to a blown piston. He said to take the car to a Buick dealership, that this repair should be a recall, that the engine is most likely blown, and that no one with rebuild that engine.

50 Engine And Engine Cooling problem of the 2018 Buick Encore

Failure Date: 01/10/2025

I have been alerted by general motors, via a letter that I received in March, 2024, that, due to a defect, my car's (a 2018 model year Buick Encore) engine may have a "condition where the turbocharger could fail" and that "the engine may run rough or have reduced power. " in the letter, they have offered "additional protection for the condition" if the "condition occurs. . . Within 10 years of the date your car was originally placed in service or 120,000 miles. . . Whichever occurs first. " on [xxx], my car was at 126,819 miles, and had all of the symptoms of the issue that were described in the March 2024 letter ("the malfunction indicator light (check engine light) will illuminate and a diagnostic trouble code will set. Additionally, the engine may run rough or have reduced power. ") on may 3, 2024, I contacted gm at the phone number provided in the March 2024 letter ((800) 521-7300. ) I was told by the gm representative that, because I was "over the mileage", that any gm dealer would have to charge me a $130. 00 diagnostic fee to diagnose the issue, and, that even after diagnosing, there was no guarantee that gm would fix the issue, because I was "over the mileage". The gm representative also said I could ask the dealer to waive the diagnostic fee, at the dealer's discretion. If, after paying the diagnostic fee, and if the diagnostic fee revealed that my car did have the "turbocharger fail condition", that I could then contact gm to see if they would cover the repair cost. In may, 2024, my car was at about 128,000 miles. I contacted two gm dealers: les stanford Buick in ferndale, mi, and james martin chevy in detroit, mi. Both refused to waive the diagnostic fee. So, in other words: - gm has created a defective, potentially dangerous product, that gm acknowledges is defective. - gm created a warranty extension in which gm arbitrarily extended the warranty mileage and time.

Failure Date: 07/16/2024

There are many Buick Encores, including 2018 that have a problem with acceleator position sensors. My car’s VIN # shows that it does not have this notice, and thus no problem. However, in July this 2018 Buick Encore went into ‘limp mode, check engine light came on. Code for problem was 2138 (accelerator pedal position sensor) the initial dealer solution was to apply dielectric grease. However, this ‘cure’ lasted . 15 miles, when it went into limp mode,,, again check engine icon came on this is very dangerous, as it cannot accelerate and from a stop, it does not move until a minute later… that is so frightening, I again took it to the deaer, same code of p2138, and now they recommend the accelerator pedal positon sensor replacement…. This is identical to the problems with the other Encores, this is a severe safety issue, and the rest of the 2018 Buick Encores should be included for notification and repair .

The turbo on my 2016 Buick Encore hasn't been working right for about a year. My engine light has been on consistently everyday for about 8 months. I've taken it to the dealer to get it repaired, and there is a bulletin - reference number a212338300 - but for some reason my VIN doesn't meet the requirement of the turbo replacement - even though the bulletin is for a turbo replacement. Why is my turbo not covered by the bulletin? clearly there is an issue with the part since a bulletin exists in the first place.

66 Engine And Engine Cooling problem of the 2016 Buick Encore

Failure Date: 05/15/2024

2016 Buick Encore VIN [xxx] approximately 60,000 miles. The vehicles turbo had a catastrophic failure pushing oil into the engine, and the catalytic converter causing extensive damage to both. The description from the first mechanic shop, I took it to descripted it as the turbo exploded, spewing oil everywhere. Buick knows the turbo engine is faulty and they issued a 'special' warranty, however the warranty doesn't cover the damage caused by their faulty turbo engine. There wasn't anything I could've done to prevent this. In fact, the gm dealership replaced the turbo and that turbo failed and had to be replaced. I've been asked to cover the cost of repairing the engine, catalytic converter and clean the oil that sprayed the engine compartment. In hindsight, Buick should've issued a full recall on the turbo. They made a business decision not to recall the turbo, but they need to accept responsibility. Living in rural northern wisconsin, we are fortunate that this didn't happen in the winter. The resolution I seek is gm/Buick accept responsibility and cover the total cost of repair. This isn't directed at any of the gm/Buick employees I've dealt with, they have all been courteous and professional. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
