We took our 2018 buick encore in to get the turbo fixed for the recall. The mechanic told us he can't test the turbo on it because the oil line going into the turbo isn't working and he has multiple other vehicles in for the SAME issue and they have been sitting in his back lot since December because he can't get the part in because everyone is out of stock. We will have to pay out of pocket for the oil line issue which will be $2300. So the turbo going bad is not the only issue this recall should cover. Because the oil line supplying the turbo should be included with the recall!

I have been employed in the Automotive Parts and Repair business for over forty years. I notice my vehicle exhaust sounded different than usual. I suspected the flex pipe part of the front exhaust pipe was leaking. This was confirmed by my local auto repair shop during a service visit. During my time as GM Parts Manager I can speak from experience to the problems these flex pipes cause because I kept two or three of them on the shelf to repair vehicles. My concern is exhaust fumes entering the passenger compartment of my vehicle because the flex pipe leaking which is just off the exhaust manifold. I contacted the local dealership where my vehicle was purchased because there still is a "Emission Warranty in effect. My 2018 Buick Encore has less than 50000 miles on it. I also contacted the Northeast Region District Service Manger with my concerns.

When driving, the vehicle will stutter and make the car feel as though it-??s bubbling, once you come to a stop, the vehicle will shut off. This is a huge safety concern considering I have children and if the vehicle just turns off and I shouldn-??t be braked for a while I can get hit. I have almost been hit 4x since this has started because the car shuts off when attempting to brake or braking completely. After speaking to multiple mechanics over this car it seems to be a common issue for it.

With estimating my months over a span of 4 months I had my turbo charger replacedbecause it had gone bad. I was out of town the light came on. And when I return I took it to the shop they diagnose it and said it was a turbo charger. I had an extended warranty on the car so they replace the turbo charger with no problems give me a rental with no problems everything was covered.. and a month and a half later my engine light came on and I replaced the purge valve another month or so later the engine light came back on and it was a turbo charger gone bad again. It took about week to find out why the turbo charge went bad. They finally said it had something to do with the return and supply line like there was no lubrication coming through a hose tthat runs to the turbo charge. This is the only place that I've had my oil change since I bought the car from king Cadillac Buick GMC. I went one other place one other time and that was it.I wonder why they did not check the supply line when they change the turbocharger the first time is that not a part of changing the turbo charge. I was told that they have seen this issue before but not a lot.when this first happened I was on interstate 40 on my way to was to salem North Carolina. And I noticed a decline when I went to celebrate on the gas. When it happened the second time I was riding to church here in my hometown and the engine light came on and just riding around hell is as if the car did not want to go like I would give it to gas and it would hesitate or not want to drive.

When it rains most if the time the vehicle onstar sets off alerts for my antilock brakes and stability to be checked. Dealer said it is normal and not concerning but checked at the 1 year inspection for me. Npf. A month later a rainy day, alerts, and the vehicle wouldn't start. All the lights came on, 'press brake to start' appeared but pressing break did not start it. After an hour of trying various 'tricks' it started with the remote starter. A week later same thing. Rain, alerts, and no start. This time 2 hours of trying various tricks- (emergency break on off/ park pushed all the way up, wheels forward, remote start attempts, onstar diagnostics etc) I had to have it towed. The mechanic from aaa tried and nothing, we towed an hour back to dealership and he tried once more, nothing. Next morning the dealership reported npf. I am picking it up tomorrow but expect to report this happening again soon.

There is a malfunction with the turbo hose on a majority of 2018 Buick Encore's that require a new hose. There is a nationwide back order on these parts due to all of the repairs. When this item broke I was driving about 70 mph on the interstate, there was a loud pop from the engine compartment and the vehicle would not accelerate appropriately.
