If you still think of Buick as a brand for octogenarians with a taste for whitewall tires and vinyl roof treatments, it's time for a reboot. The Regal is a thoroughly developed and satisfying midsized sports sedan. That European feel is no coincidence, since the Regal is based on a German design from GM’s Opel division.

These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for over 300,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2021 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Took it back to dealership and found out that the leasing company had installed an aftermarket systems that caused this problem. The dealership paid to have the problem repaired."

    Jim O., NC (2015 Buick Regal 2.0-L 4 Cyl turbo)
    Display screen goes blank

    "the whole infotainment system doesn't reset itself as it shoud. Buick told me to bring it in but I fear it is going to be a problem that is going to be fixed but the 50,000 bumper warranty is up in 5,000 more months."

    Robert K., NJ (2015 Buick Regal Base 2.0-L 4 Cyl turbo)

    "Was in the city at dentist. When finished with dentist went to my parked car and drove towards home. Usually the screen comes on slowly so I kept driving even though screen was blank at startup. All the way home , maybe 10 miles, screen stayed blank, no speedometer on highway. Got home shut car off, hour later when needed to use car agin everything was fine."

    Richard N., NY (2015 Buick Regal GS 2.0-L 4 Cyl turbo)
    External music device interface (e.g., smart phone, MP3 player)

    Anonymous, ME (2015 Buick Regal Unsure 2.0-L 4 Cyl turbo)
    Phone pairing (e.g., Bluetooth)

    "Have to disable Bluetooth to get Google Maps voice directions on iPhone 6. Appears to be an Apple iOS issue - sometimes updates fix it, sometimes they break it"

    D R., PA (2015 Buick Regal Premium II 2.0-L 4 Cyl turbo)
    Radio

    "The battery was replaced and afterwards the presets for the satellite stations were not able to be reset."

    Anonymous, NJ (2015 Buick Regal)

    "The car was brought in for a new battery. Once the new battery was connected the preset station for the satellite radio were gone. The radio now will not allow for the stations to be preset once again. This only occurs for the satellite stations. AM/FM stations are fine."

    Anonymous, NJ (2015 Buick Regal GS Unsure)

    Speakers

    "Sound bad. Poor midrange. Chinch treble. Nowhere near the expected quality for this level of vehicle."

    What Owners Say

    Air or water leaks

    "After driving several hours on a trip in steady rain when reaching into the glove box to retrieve a small writing tablet noticed is was very wet. Later( several days) Had a local credible repair shop do some type of air pressure test on area around glove box and no leaks were indicated at all? To this day we have not driven in any rain even near incomparison but what rain we have experienced(including car wash) did not cause any further leaks. So far only consider the leak an anomaly but there is no doubt there was a leak of some kind. It was only my wife and I on a 2 day trip and no liquid or liquid container was placed or found in the glove box? I probably should have reported it to the Buick car dealer where I purchased it but checking the warranty that was still valid I could not find anywhere leaks were covered."

    Anonymous, KS (2015 Buick Regal Base 2.4-L 4 Cyl)

    "Water Leak while raining put over an inch of water in trunk and floor of back seat."

    Barry F., OH (2015 Buick Regal Base 2.0-L 4 Cyl turbo)
    Seals and/or weather-stripping

If wipers need to be on continuous it is totally gyrating . #2 ...when changing back to my summer tires and wheels the road noise is almost unbearable especially on a highway .. this is my 3rd summer to own the car with these wheels and tires and they previously were not loud like this"

    Richard N., NY (2015 Buick Regal GS 2.0-L 4 Cyl turbo)

Therefore, although I enjoy the car, I would not get it again. It did teach me to take a test drive at night before buying or leasing any model vehicle in the future"
