My engine light came on 4 days prior. Took to repair shop and code showed PO OB6. I was informed there is a small pinhole leak of antifreeze by the Head Gasket at the block. There is only 63k mileage on this vehicle and if I had blown this gasket I could have put me at risk or others had this blown a gasket. I just cant believe this is happening since there is not much mileage on this vehicle. Please research.

I pulled out of a gas station and about 1 mile down the road my car all of a sudden would not accelerate; it was stuck at a maximum of 35mph. The transmission/check engine light did not go on for at least another mile until I was able to pull off the side of the road. Car was towed to a local AAMCO where it was determined that entire transmission failed with no warning whatsoever.

I was driving on a 70mph highway. Went to pass slower vehicle. The car did not react to the accelerator. In fact it slowed down with the engine trying to rev up. Luckily, there were no other vehicles trying to pass at the same time because I had to drop back. Car is currently at a Buick dealership for engine propulsion repair. Do not have complete estimate for repair yet. Was told could be approx $2300. One year earlier, at 50000 miles had similar acceleration problems because of catalyst converter. The catalyst converter was replaced under warranty.

While driving my car on March 26, 2020, my engine light came on. I took my car to keller's professional auto, who detected that my turbo had a crack all the way across, so I had to replace it. I only had 45,352 miles on my car. According to keller's and my research, the turbo should last for 100,000 to 150,000 miles.

My vehicle was in motion on the highway at an approximate speed of 65mph and suddenly I heard a strange pop. My car immediately went into limp mode causing my speed to drop to 25mph on a moderately crowded interstate highway. Due to the dangerous nature of this issue, I drove on the shoulder to the closest exit and drove the car to the closest dealership. 6 different trouble codes were pulled on the vehicle. I purchased my vehicle less than 6 months ago along with a gmpp extended warranty. For two weeks, the warranty could not be found and I was calling numerous warranty companies trying to find out what occurred with my warranty. After the 2 weeks of calls and confusion, the dealership stated that they would cover the PCV valve issue that they had diagnosed to be the problem. The dealership never stated that the PCV valve malfunction was in fact a "special added protection issue" put out by GM in August. I finally received my vehicle back two days ago and the car is still not working as it was before this repair. It is idling hard and at high RPM and also hesitating during acceleration.

Cracked valve cover first occurrence was August of 2017. This was replaced under warranty. Second occurrence happened January 6,2019. This occurrence caused multiple failures and cost me $727 to have repaired. Symptoms were noticeable off shift points due to lack of power and too much air to turbo. Also a surviving of the engine when going up steep hills. This is a known issue as both times the dealer knew what the problem was and had parts on hand to fix. I took video of both times for my records.

Battery West even a year old and it went out. Dead. Coolant was leaking. But wasn't leaking at first. I believe they damaged it. When we took it for check up the same warranty was going out and they said we will make sure everything is working. They just half fix every thing and got the money. This is a lemon.coolant leak and conditioning still don't work.what do you do.just
