general problems of the 2012 Buick Lacrosse

Sometimes car is dead in the morning, unable to jumpstart, 1 hour later car starts right up, drives fine for a while then dies, has died while waiting at a stop sign. I have taken it to two auto shops including the dealer. The first auto shop could find nothing wrong, the dealer told me it was my battery (which was only 1 year old). He replaced the battery but my car continues to randomly die.

Affecting all 2. 4l gm motors- the exhaust manifold will crack just before the catalytic converter and leak deadly exhaust fumes into the cabin. You may experience a smell at first but then it goes away and symptoms will typically include headache, nausea and vomiting. Seek medical attention immediate as carbon monoxide is odorless and colorless and deadly. This has been seen on multiple vehicles a week in the shop.

My vehicle is stalling and takes a long time to crank after re-fueling. I took the vehicle to a local dealership and they are suggesting that the purge valve selonoid needs to be replaced, how may other complaints have been reported? please advise if there will be any action taken regarding this. As soon as possible.

Whenever I put fuel in the car it has a hard time starting and will also stall occasionally. It's been happening since June 2018 and I have had a mechanic try to fix it and they can't figure out what's causing it to do this. Are there any recalls for this.

Purge solenoid valve had to be replaced the defective device caused the vehicle to loose power while driving and caused long engine cranking after re-fueling the vehicle.

While driving downhill, in mountains, I was turning right on a curve at 60 mph when I lost all acceleration. The vehicle slowed to approximately 30 mph in about 10 seconds. The motor was still runing but at an idle speed. After about 15 seconds, the accelerater started working again. Cars were behind me honking, it scared the --- out of me. The next time it happened (4. 23. 2015), I was changing freeways, turning to the right at about 30 mph, the accelerater again stopped working with 4 cars behind me, one almost hit me in the rear, there was no place to pull off to. Then after about 15 seconds the accelerator started to respond again, so I could drive again, I took it to the dealer and informed them what had happened, they told me that they had not heard of any problem as I reported. They did an inspection of the vehicle, checked connections of wiring. I informed them of the same problems reported on the internet that I found, they said you can't believe everything you read on the internet? they could not deplicate the problem.
