The most common 2020 Buick Enclave problems

While the Enclave has only received ten official complaints, the mechanical issues reported can be cause for great concern. 
The primary weak spot of the 2020 Buick Enclave is its powertrain/transmission. Four drivers have reported that their vehicle would jerk forward when shifting gears or traveling at low speeds. The occurrence was reported around 2000 miles and persists even after the car is taken in for service.
The National Highway Traffic Safety Administration (NHTSA) has recorded an incident where the Enclave accelerated forward without warning when put into drive, causing injury to the driver.
Another common issue that drivers have experienced is a
grinding noise
from the brakes. The issue resurfaces even after the pads and discs are replaced.
Other complaints regarding the 2020 Enclave include: 
  • OnStar system and Wi-Fi issues when the radio is in use
  • Front doors freeze easily in winter
  • Poor fuel efficiency
  • Ticking noise when the vehicle starts
  • Electrical system issues
  • Faulty fuel tank sensor
  • Car jerking without warning
  • Vehicle speed control
  • Faulty forward collision avoidance system
The 2020 Buick Enclave has 6 recalls listed on the NHTSA website, including:
  • Tire failure causing sudden air loss
  • Overcured tires may experience a carcass break
  • Missing bolts on the start/stop accumulator
  • Engine stalling without warning when there is an insufficient fuel supply
  • Roof rail airbags may not deploy
  • Potential crack in the right-hand frame rail
While a few of these complaints are minor inconveniences, most of the issues are mechanical failures that can lead to an increased risk of a crash. Fortunately, these issues have a low occurrence rate, so don’t rush to get rid of your Enclave!

Is the 2020 Buick Enclave reliable?

Overall, the 2020 Buick Enclave scores below average in reliability for a midsize SUV (24th out of 26 on RepairPal). 
If you want a reliable SUV, a luxury model may not fit the bill. The Enclave's less prestigious counterpart, the
Chevy Traverse
, scores higher for its reliability than its up-market cousin.
RepairPal gives both SUVs an average 3.5/5.0 rating for reliability, but J.D. Power rates the 2020 Traverse 85/100 for quality and reliability, while the 2020 Enclave scores 79/100
The average annual repair cost of the 2020 Buick Enclave is approximately $720—that’s higher than average for a midsize SUV. This could be due to more frequent unscheduled repairs and a higher chance of serious issues.
