My check engine light came on along with my traction control light, and "Reduced Engine Power" popped up. This is connected to a recall on this vehicle for a connector at the throttle pedal.

RECALL NOT COMPLETED? The previous GM Buick Dealership I went to, appears they will not or can not confirm that the Buick June, 2022 Recall (Braking issue) work was done in October, 2022 at Key Chevrolet Buick GM in South Burlington, VT. I have contacted both the Dealership and Manufacturer (Buick) current Case # 9-10190079245 twice and Buick (Corporate) is trying to contact the Key GM Buick Dealership to confirm the Recall work has been done and if done, then remove the still pending Recall notice that is still showing the Recall still needs to be done.

@ 40,000 miles The Buick Regal Tour X is making a loud humming noise from shifting gears from the transmission and a noise near the engine, when slowing down to 5 mph, loud humming noise can be heard. I took the car to GM service department and the mechanic told me he couldn't find anything wrong. I told him Yet, Yet?? I want to be proactive on this transmission issue.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Buick Regal Tourx verdict →
