2017 Buick Envision engine complaints

Filed Apr 14, 2018 · Engine, Lights · 5,000 miles · NY

Car makes a scrapping sound. Spent 32 days, then 22 days at the garage. At the 32 days torque tube to drive shaft changed. Noise came back. At 22 days buick sent a field rep. To work on envision. Invoice said they loosened & retorque the frame that attaches the rear differential to the unit body of the car. With my case buick called & told me the garage changed a carrier bearing. Asked the garage why they said that. Was told they had to put something down to get paid. Buick ended up doing a repurchase. Now we have the same noise in the replacement buick envision 2017. Another issue with this SUV is the dash lights. It's sunny out & you get in a shaded area & they go out. Dash is so dim sometimes you can't see your speed or your gages plus radio. There is a wheel to brighten or dim the lights. You roll the wheel up to have a bright setting & it rolls back, like it's spring loaded. July 14, 2017 was the first trip of many to the garage. The noise is sporadic. It doesn't matter if you are going uphill, down hill, left or right. The garage know how to make the noise. They drive 50 -55 MPH & drop the car in low. This puts the car in 6th gear. We don't do that. It makes the noise. Was shocked that they figured our how to make the scrapping sound.

There is a problem with the exhaust system or maybe not, with a horrendous groaning rattle that occurs within specific parameters. At about 45-50mph, if cruising with almost no acceleration, when you do accelerate, you get an awful rattle that sounds as though it is coming from the exhaust system. It is startling and in of itself doesn't seem to be a safety item except it startles you. Dealer indicated when brought in that road salt, small stones, etc. Had settled on top of the fuel tank and caused this god awful sound. They said they blew it out and the problem did appear to be fixed - except it took only a week for it to return. If what the dealer said was true, there is a gap between the fuel tank and body that allows normal road debris (salt, pebbles, etc.) settle up there and cause this condition to occur. Not a safety issue except it is distracting and startling when it occurs. Could be a safety issue if other things get up there, like a rag or cloth, and it rides against the exhaust system, while lodged above the fuel tank, and catches fire. That as not happened, but imagine it is possible given the circumstances.
