There are 2 owner-reported fuel system complaints for the 2016 Buick Veranoin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Fuel Sending Unit. Yes. Loss of power and control of vehicle due to no fuel. Mechanics have confirmed it as a common problem with GM fuel sending unit/pump No. No warnings, no lights, no indication of problem. I received a second pump and sending unit from GM and had the same problem for a 2nd time of fuel reading inaccurately and causing me to lose vehicle functionality.
Fuel level sensor failure. I haven't checked but I don't think a regular dealer would inspect for free because it's inside of the gas tank. The gas gauge gets stuck at around a quarter of a tank leading a sensible person to assume their is gas in the vehicle. This is a safety risk because your vehicle can stall in the middle of the road as it did in my case. You lose the ability to steer the vehicle and put other vehicles behind you or around you at risk. The problem has been reproduced by me when comparing the range for my vehicle (396 miles on a full tank) then resetting the trip after filling up. I then drove the vehicle across a couple weeks and the trip said I was at 335 miles and the range said 96 miles, which is an overestimate from the predicted range when filling up. I drove another 30 miles for work in the same day and the gas guage seemed to be in the exact same spot as it was earlier (and when I was stalled the time before) and my predicted range actually went up to 102 (pictures to prove all of this upon request.) And at 365 miles, it would be impossible fir my car to reach another 100 plus miles in range. My gas tank holds 15.6 miles and my average fuel economy was 25.5. When I filled the gas tank up after this trip, it put 14.7 gallons in which means I had .9 of a gallon. 25.5 × .9 is roughly 23 miles. Completely way off from the "predicted 100" it said before I filled up. Personal dealers have been completely unaware and I'm afraid to take it to a dealer in the event they try to charge me for it. No. No, there is no warning light and no check engine light. Gauge and light check works properly when vehicle is started and it runs the quick diagnostic by maxing out the gauges and turning on all of the dash lights.
