There are a couple of issues causing our concerns about the car. 1. Alternator - The alternator was reported went bad after only 4 years of usage, the dealer refused to pay the fixing cost for this. Due to the failure of the alternator, the car lost all the power in the middle of the road with our entire family in the car during the night, very dangerous. The car suddenly stopped at the road with 50MPH speed limit. 2. Engine and Catalytic converter pipe - The engine light is on due to abnormal feeling of the engine power, the dealer could not fix the issue in weeks and no rental car provided and we were asked to drive the car home and waiting for order status of the parts. 3. Exhaust system failure - The dealer mentioned the welding of the connection is bad ( still under warranty ) but refused to fix it but ask the customer to pay for the replacement and labor.

Evaporative emission canister purge, solenoid valve, yes. My safety was at risk due to stalling 3 different times on busy roads/intersections after refueling my vehicle. When the Solenoid valve and canister fail when coming to a stop after refueling it causes the car/engine to flutter and completely stall then goes into neutral. It takes multiple restarts in order to even make the car go along with pressing on the gas. This part has been replaced twice by the dealership once at the end of march and again on the 10th of June. The first incident occurred mid-march, the second end of march and the latest incident occurred 7 June where I had to restart it 7 times before it would even drive, at that time my check engine light was on and it was making a loud noise. After this last replacement the vehicle was refueled and it started to flutter and idled hard, it will be taken to the dealership once again on the 20th of June. The vehicle has not been inspected by anyone other than dealership. There were no warning lights prior to the failure, the only indication was the car started to flutter prior to stalling. The most recent date is stated below.

The contact owns a 2019 Buick Enclave. The contact stated while driving downhill, he shifted to a lower gear and was depressing on the brake pedal however, the vehicle inadvertently accelerated. The contact also stated that the RPM was very high. The contact stated no warning light was illuminated. The contact stated he continued driving but had to stop 5 times to allow the vehicle to cool down. The contact took the vehicle to the local dealer. The mechanic found no failure with the vehicle. The contact stated that the failure persisted. The manufacturer had not been informed of the failure. The failure mileage was approximately 30,000. Contact was on top of Pikes Peak in Colorado. The fast idle has the engine revved to high so that when foot was off the brake on a 5-8% slope the car accelerates to 6500RPM with in 250 feet taking the car to 30MPH in low gear. Consumer had to push on the brakes constantly, all the way down the mountain which caused the brakes to severely overheat. Park ranger measured the temperature of the brakes at 375 degrees F it was after consumer had stopped to allow them to cool 3 times in about 4 miles. The car will idle at 950RPM stopped and will lurch forward when foot was off the brake. Driving on the highway speeds its fine but not on switchback mountain roads.

The seal around the timing chain was leaking right from the first day we bought the car. The camshaft was also pitted and replaced. It was fixed by the dealer under warranty. This also happened on our 2009 Buick Enclave. It leaked a large amount of oil that could have caused major engine damage.

I have had this new car just over for 1 year, im prior service military and was able to purchase this 2019 Buick Enclave for me on father's day last year because pur other car broke down on a family road trip. So I garage my vehicles I noticed a oil leak on the garage I didn't want to think it was from this car so I watched it seemed to be intermediate at times but recently got worse so I took it in told them and they said it was a bad oil filter but the oil filter is opposite side of the car from where this leak is dripping on my driver's side. So I just went under there to see what I could find I too was a mechanic in the army and outside as a civilian after so I looked took me 5 seconds to locate it that is the picture of the leak. Then I noticed rust cracks on my frame so I looked more and discovered the rust cracks are on the bottom and topside of the frame. So I did some research and saw coming up in Dec a recall is going to happen for cracked frames on the Buick Enclave 2020 but starting from build date's 3 months after mine was built but mine shows all the systems of that recall but isn't included. Also I had a issue with the starter stop my family and I were stopped at a red light on a city street with a car infront of us when the engine stopped normally then when it turned back on my RPM kept going up like your pushing the excellorator peddle but I wasn't because my foot was on the brake when I look down I eased up a bit on the brake and it shot forward on me I didn't hit the car infront of me because I depressed harder on the brake to hold it. Thats when I started looking and saw this recall soon to come out.

Traveling at highway speeds car suddenly shifted itself into neutral and could not be engage back to any drive gears. Brakes were inoperable and accelerator was in operable. Finally came to a stop by coasting to the shoulder and waiting for speed to drop far enough to get vehicle to go into park.

Note: Mileage is 1240 miles, just purchased three months ago with 54 miles on it and shipped to germany (dod civilian). While in europe, I am using the vehicles' "metric" setting (kph versus mph), which switches the speedometer to read kph and auto tunes the engine to the appropriate levels to match kph. I have been driving this vehicle for the last three weeks until the issue happened last night around 1830 hours cet. Issue: While accelerating and tuning left from a stop (stop light with the city), the engine suddenly loss power then jerked into a lower gear, but somehow got stuck in 3rd gear restricting max speed of about 25-30 mph running at 5000 rpms. After several attempts to stop, start, and proceed, I found the vehicle seem to be slipping when shifting from 2nd to 3rd gear, but would not go beyond 3rd gear causing the engine to strain and rev at an unsafe levels. Tried several times to shift to "L" to manually engage the engine, but it kept changing back to "D" automatic. Also noted that when the vehicle reaches the next programmed gear shift (e.g. 2nd gear to 3rd gear) it then jerks, stalls for about 2-3 seconds, then suddenly engages 3rd gear running at extremely high rpms and never shifts beyond that. Now check engine light is on. Vehicle has never been in an accident, damaged, or wrecked.
