general problems of the 2014 Buick Encore

Coolant leak and cover gasket failure. Buick has been in the shop multiple times for coolant issues and leaks. Next step is for the shop to remove the entire front end to adequately repair. Constant issue and other complaint relay the same.

On March 18 , 2025 I purchased a 2014 Buick Encore with an implied warranty, the vehicle had 128,644 miles on the odometer. At the time of purchase the check light was not on and the vehicle had no visible or audible mechanical issues. Not 14 days after purchase there was a strong odor of burning oil due to an oil leak dripping into the splash shield. A certified mechanic advised me that the problem was a very common issue with the 2014 Buick Encore and the oil cooler associated with the turbo charger needed to be replaced. This issue is so common that the NHTSA issued a gm part failure warning for the 2017 model and instructed gm to reimburse all vehicle owners to replace the part (n232395330). This issue clearly a problem that needs to be addressed with the 2014 model as well. My mechanic said that auto dealers are cleaning the splash pad prior to selling the vehicle so that the burning oil smell is not noticeable until 14 days or so after purchase. The repairs cost me $1148. 00 just weeks after purchasing the vehicle. This problem of dealers covering up the problem and faulty gm parts needs to be addressed. I believe my vehicle falls under the previous gm parts needs failure warning and I should be reimbursed the cost of the repairs in the amount of $1148. 00.

There is only 63k mileage on this vehicle and if I had blown this gasket I could have put me at risk or others had this blown a gasket. I just cant believe this is happening since there is not much mileage on this vehicle. Please research.

Also a surviving of the engine when going up steep hills . This is a known issue as both times the dealer knew what the problem was and had parts on hand to fix . I took video of both times for my records.
