2020 Buick Enclave Problems And Complaints

2020 Buick Enclave User Complaints and Problems

Mechanical Complaints

• Transmission- The transmission has been the primary weak spot of the 2020 Buick Enclave. Owners have been complaining about the unit jerking when slotting between the drive selector and when the unit is shifting through the cogs in auto mode. Even though the TCU was reflashed from the dealer, the issue persists in many users. One low-speed crash has also been recorded by the NHTSA on this issue, where the vehicle lurched forward without warning when slotted into drive. The average mileage of occurrence of this problem is around 2,000-miles.

• Service brakes- Grinding noise from the brakes is another common issue on the 2020 Buick Enclave. Owners who got the pads/discs replaced under warranty still complain about the issue coming back soon even though they got the components changed, Aftermarket brake pads are the only working resolution to this complaint.

Electric System complaints

• Infotainment- OnStar system and Wi-Fi connection on the media system is said to go out intermittently on the Buick Enclave.Even though the dealers are aware of these issues, no software update on this glitch is made available. The official helpline is also said to be cumbersome with their help when approached.

Structural Complaints

• Front doors- The front doors on the 2020 Buick Enclave are said to freeze easily in winter preventing access to the vehicle. Melted ice between the door and the frame freeze over time preventing the doors from opening even if the system unlocks. Poor door sealing is the reason for this complaint.

Safety Complaints

• Forward collision avoidance system- Not a widespread issue here, but the auto emergency braking system is said to be faulty on the 2020 Buick Enclave. The user complained about the vehicle moving on itself and hitting the car in front multiple times in adaptive cruise control mode without warning, whilst laying stationery for a red light. Since the issue was a one-off and could not be replicated by the dealer, no further proceedings were made on this issue apart from a system check.

Should you buy a used 2020 Buick Enclave?

The Buick Enclave is a premium-tier midsize SUV you could get your hands on without breaking your bank. As good as it is, the reliability part of these SUVs is far from the best we have seen in this class. Even though this generation of Enclave SUVs was brought out in 2018, the issues seem far from being sorted out, especially with the transmission side taking a major blow on low run vehicles and the recall numbers seeing an all-time high with the 2020 model year. All though we were decently impressed by this SUV on our short test, it ends up not being quite that promising in the long run making it hard for us to recommend it as a good used buy even if you have seen one listed for sale at a good deal.
