Lincoln
Predicted Reliability Rating: 54/100

The 54 out of 100 that the people at Consumer Reports gave Lincoln for 2023 may be a little misleading because it was brought down because of one car. Just one. The Corsair and the Nautilus were both at the high end of the survey, receiving an 82 and a 73 in that order, with current owners claiming that they would repurchase them in the future. But the problem child, the Lincoln Aviator, gave the entire brand a bad name.
- Avg. Yearly Maintenance Costs: $879 (RepairPal)
- Est. Maintenance Costs For The First 10 Years: $12,099 (CarEdge)
- Worst Models To Buy: 2023 and 2021 Aviator
Since the Lincoln Aviator started production again in 2019, it has had more than its fair share of problems. Some of the most common complaints cover almost every section of the vehicle, including the in-car electronics, the drive system, the suspension, the steering system, seals and seams against air and water leaks, the electrical system, paint, and trim. The good news is that the body hardware and transmission will last a reasonable amount of time.
Buick
Predicted Reliability Rating: 54/100

Buick has been a brand through the years that has never truly been in the limelight, but it has hung on with some great cars such as the Buick Regal, LeSabre, Riveria, and the Park Avenue. They have all been reliable cars that offer good luxury and comfort at a decent price, but as the world has moved into the new age of technology, numerous Buick models have been struggling.
- Avg. Yearly Maintenance Costs: $608 (RepairPal)
- Est. Maintenance Costs For The First 10 Years: $9,063 (CarEdge)
- Worst Models To Buy: 2023 Encore GX, 2022 Envision, 2016 Enclave
Buick cannot point the finger at one specific model, so they need to take a hard look at the problems reported with the brakes, the engines, the fuel systems, and the emissions components. Granted, the Encore GX, Envision, and Enclave do not have the same issues reported across the board, but since they all fall within the 50s out of a 100 range, it is safe to say that the problems need to be addressed in all the models.
13Genesis
Predicted Reliability Rating: 52/100

In 2003 Hyundai/Kia decided it was time for them to throw their hats into the luxury market ring. Since then, Genesis has done very well for itself, taking away a spot in the luxury market from some of the top rivals in the class, such as the Audi A6, Lexus ES, BMW 5-series, and Mercedes-Benz E-class. But, like every other carmaker in the world, along with the good, they have some bad.
One of the craziest things to see when looking through the Consumer Reports breakdown of any of the Genesis models is that the customer satisfaction ratings are 5 out of 5. Now, that is kind of a contradiction when you see the reliability ratings given to the Genesis GV80 and the Genesis GV70. Still, time will tell once a few hundred thousand miles are under the belt of more than a couple of vehicles reported.
