BUICK Complaints

I purchased the vehicle on 12/21/24, and I now have a check engine light with a code related to "The Engine and Transmission System is not performing as expected. An issue has been detected in the Fuel Management System used to maintain, control, and monitor fuel consumption." I am not sure if my safety is at risk as the service center cannot currently schedule a service appointment to confirm the issue.

My car has shut off multiple times , electrical shorts, intermittent no start, intermittent misfires all the time but randomly , injector codes even when replaced and injectors are good , yes come check out my vehicle no shops can find out what's the problem practically the whole front end has been replaced and problems still happening it is congruent with a recall but shows nothing from vin

Check engine light came on, reads reduced power and is causing problems accelerating

This vehicles exhaust system has two brackets that broke off the exhaust due to bad welds. There is TSB out for one of the brackets where they replace one cheaper pipe but no mention of the other. This TSB is for multiple years same issue, 2019, 2020, 2021 and 2022. Yet I was told mine is not included by dealer over the phone. There are literally thousands of complaints stretched across multiple sites with the brackets breaking off and exhaust leaking into the car after. This issue is right at the back of engine. It’s leaking exhaust right into the cabin from the venting system to the point we get sick now. It’s $800 I was told to fix the 2 pipes that are faulty. Just bought this 2 years ago and have owned many GM vehicles in last 35 years not one has ever had any issue with the exhaust system. And the one pipe that broke and cost $420 for just the part is also on back order cause they have replaced way more then normal and it’s also the part that’s not under any TSB yet.

When I park the vehicle doesn’t recognize that I switched my gear to park and it won’t let me turn my vehicle off and when I have my foot on the brake it feels like sponginess

The infotainment system locks up. Its like all features are on mute. I can't use phone, radio, contact onstarr or use navigation system I have a heart condition, when this freezes I have no way to reach help. The dealership has tried multiple fixes, they say they are just seller, GM is the manufacturer. GM no longer takes my calls. They have blocked all my numbers. There is no warning, it just stops working GM suggests I turn off vehicle, get out wait 20 minutes and the system should reset, I have tried to disconnect my phone from bluetooth and they seek each other out and reconnect. I live very rural, 20+ miles to anywhere. I have no way to get help
