The 2016 Buick Regal has a lot going for it as a daily driver and highway cruiser. It handles well, looks sharp, and the turbocharged engine gives it a sporty edge most sedans in its class cannot match.
Ask owners who have put real miles on one, and a pattern of recurring issues emerges. Knowing about the most common 2016 Buick Regal problems before they catch you off guard is half the battle. Being prepared to handle repairs yourself saves you from handing over serious money at the dealership.
Our Buick Regal (2011–2017) Haynes Repair Manual covers this model year in full, giving you the vehicle-specific guidance you need to take repairs into your own hands.
The Most Reported 2016 Buick Regal Problems By Category
Steering Failure
This is the most serious complaint filed against the 2016 Regal. It earned the highest NHTSA complaint count of any category on this model. GM issued a recall covering certain 2016 Regal vehicles where the power steering assist system could fail without warning.
Owners described the steering wheel locking up or jolting hard to one side at highway speeds, in some cases with no warning lights beforehand. The recall remedy was to replace the electric belt-drive rack-and-pinion steering gear assembly. If your vehicle falls within the affected production dates, verifying recall status with a dealer is a good starting point.
Infotainment and Backup Camera Faults
Owners reported the center display going blank, the backup camera feed jumping unexpectedly during reversing maneuvers, system error messages appearing, and HVAC controls locking up entirely.
Multiple dealer reprogramming attempts failed to resolve it for many owners. Lane-change and collision-detection systems were also flagged for false alerts on the same vehicles.
Engine Issues
Some owners experienced an internal engine defect where a fragment breaks off and travels into the oil lines, eventually reaching the oil pan and causing the engine to seize. This was reported in vehicles with as few as 50,000 miles.
Separately, stumbling and stuttering under acceleration combined with StabiliTrak and traction control warning lights was another pattern owners reported. Our Buick Regal Mk V (2010–2017) DIY Manual covers engine diagnostics and repair in detail, so you have the right reference before opening the hood.
Transmission Concerns
The Transmission Control Module (TCM) was flagged in owner reports, with symptoms including jerking in drive and reverse, unexpected stalling, and StabiliTrak warnings appearing alongside power steering alerts. One owner reported a complete internal transmission failure at only 27,000 miles.
Brake System Problems
The brake complaints on this model are not minor. One owner reported the vacuum pump for the brakes failing at 75 mph on the highway, causing the brake pedal to completely seize with no prior warning. A separate report described a fractured wheel bearing magnet ring triggering simultaneous loss of ABS, traction control, and power steering assist.
Maintenance That Helps Prevent Bigger Problems
Staying on top of the basics goes a long way on a car like the Regal, particularly if you drive it regularly on the highway. These are the routine jobs worth keeping current:
-
Oil and filter changes at the intervals specified for your engine variant
-
Brake pad and rotor inspections, especially given the brake complaints on this model
-
Air filter replacements to keep the turbocharged engine breathing cleanly
-
Tire rotations to manage uneven wear on FWD and AWD configurations
-
Transmission fluid changes, particularly after 60,000 miles
None of these jobs requires specialist knowledge. A Haynes Manual walks you through the correct procedure and specifications for your exact vehicle, so you are not guessing at torque values or fluid types.
Know Your Regal, Own Your Repairs
The 2016 Buick Regal is a capable car with some real weak points that owners learn about the hard way. Steering, brakes, and engine faults are not things to monitor passively, especially on a vehicle used for regular highway driving. Keeping up with maintenance and having a solid repair reference behind you makes a real difference in how long this car stays reliable.
