2019 BUICK ENCLAVE Complaints

The 2019 Buick Enclave was taken in for transmission fluid flush & check. The dealer came back and stated that the torque converter needed replacement. The car was still under mileage warranty but just past the roll-off-line date by a month. There are numerous issues all over the internet related to The Enclave torque converter issues. Even a service bulleting PIP5608J that covers these exact issues. It is a wide spread safety issue. If the transmission fails, what is the outcome at high speeds? It has just over 69,000 miles. Todays transmissions should last 150,000 miles minimum. Unacceptable!

The contact stated that after releasing the brake pedal, the vehicle turned off instead of restarting the engine.

The local dealer and manufacturer were notified of the failure, but no assistance was offered. The contact was informed that the VIN was not included in NHTSA Campaign Number: 20V668000 (POWER TRAIN). The contact stated that the vehicle had experienced the failure listed in the recall.

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.

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

One day, I looked over at my seat and there were literally two tears in the leather. I immediately looked to see if something had ripped them. The only thing I put over there is a small cloth lunch sack so there’s no way that that could’ve done it. there was NOTHING SHARP on the seat. I am also very good about keeping my leather maintained and car maintained . It needs to be repaired before it gets worse.

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.

I found where there was a recall on 2019 Buick and mine was not listed. It is doing what I have read about the recall. The transmission is shuttering at low speeds.

The cooling fan motor assembly is shorting out internally & blowing the 70 amp fuse dedicated to that circuit. Mustreplace fan assembly and fuse to correct this concern

We were on a trip home from the Holidays about 400 miles away when we heard a huge explosion! The front sunroof exploded and rained glass all over us. It was a clear night with no other cars around. We had to pull over and find something to cover over the sunroof because it was so loud and shooting bits of glass all over us and our dog. We made it home. We are still waiting on insurance to fix it. This really scared us.

The contact owns a 2019 Buick Enclave. The contact stated that upon the start of the vehicle, a loud grinding noise would emit from the rear end of the vehicle. To correct the failure, the contact operated the vehicle in front-wheel drive instead of all-wheel drive. The vehicle was taken to a dealer for service, but the contact was given a diagnostic fee and declined. Upon investigation, the contact discovered that the cause of the failure was linked to the rear differential. The manufacturer was notified of the failure but offered no assistance. The vehicle was not repaired. The failure mileage was approximately 87,000.
