2019 Buick Enclave: check engine light

Filed Oct 11, 2026 · Electrical, Transmission · KY

alternator failed approximately 2½ years earlier, and the alternator and battery were replaced. another alternator and battery installed the following year. * A pulley bolt broke while I was driving and was replaced. * I subsequently had problems with the serpentine belt squealing and producing a burning-rubber smell, and the belt was replaced. (Or so I thought.) The burning didnt go away, neither did the belt squealing. After the belt installation, the battery light came on. correcting the belt restored charging to approximately 13.9 volts. Despite that, an intermittent squeak or squeal when taking off continued. Next, A static-like sound from the radio with the Dashboard lights becoming extremely bright. And car stopping in the middle of the road. A really horrible burning-rubber smell. I turned the car off and then tried to start it again, and the symptoms then returning to normal. But the battery was running very low voltage. 11-12v. Everything went back to normal the next day. No check engine light had come on. A check-engine light and intermittent codes did appeare and disappear every so often. codes P0113, P00F4, P2229, and P0430 , and an EVAP-line issue at another time. All would cut back off. Then came the final issue. The transmission “banging into gear” or making a hard thunk when engaging.Also transmission-fluid leakage and occasional shuddering. The check-engine light was off during these later symptoms. Through my research, all of these issues were related to a particular transmission issue through the electrical system. The faulty electrical has caused many issues leading to this transmission issue. That have put me and my children in dangerous situations in the middle of the road multiple times.

Start/stop function malfunctioned in the middle of the road, this has happened multiple times before and after replacing starter and battery, looked at by several mechanics. If I stop the car at a light or in traffic my car will dint turn back on or let me shift. Thus a safety issue because I could have been hit as it stopped in a busy road and people had to move around my vehicle. Engine light came on after failure and ceased the engine and i couldn’t move to the intersection. I also just got an oil change. They first appeared a few months ago and I had already gotten work done on it and it keeps happening

On Sept 6th the check engine light came on. A diagnostic test showed it was code P0442 related to the canister purge valve /solenoid. It also showed that it was a permanent thing that had been on there a while but when I look up my Vin number there is no recalls for it, but there is for other 2019 Buick enclaves.

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.

Traveled and car begin to shake when I got to destination. The shift gears lights started going from neutral to Low gear and my speed began to drop down even when I was accelerating. The engine light came on and the stabilitrak light was on during times I stop at lights or stop lights only when in traffic but not on the highway. After seen by an auto service dealer, the stabilitrak light still comes on during stops at the light or stop signs and hesitation to accelerate with a heaviness to steer. There appears to be a dragging or pull when accelerating not very smooth. The service was with the transmission, however, no attempt to fix the stabilitrak and now I am to take it back in, not really enjoying my vehicle, my American vehicle, this really saddens me.

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.

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.
