Other Fuel System Problems of Buick Enclave - part 1

As someone who has been in the car business his entire life, the below TSB is utter bullshit. My 2025 Enclave with 3400 miles on it had a catastrophic and copious amount of transmission fluid. On my tile floor in my garage and all over my driveway a minimum of 5 to 7 quarts. . Had my wife been driving the car with my grandchildren as a guarantee it would’ve locked the transmission up and evacuated all the oil as it is on the high-pressure side of the pump. Based on my knowledge of recalls, this should be a stop sale and a recall, not a TSB why have they been given a pass on this? https://static. Nhtsa. Gov/odi/tsbs/2025/mc-11014291-0001. Pdf.

Check engine light was on due to the evap purge solenoid not sealing properly and causing a leak. Scan testing performed of the engine control module and diagnosed/cleared dtc p0496-00. Vehicle was brought to a dealership for repair.

The dealership is unable to identify the failing component or system. The vehicle shuts off while driving above speeds of 60mph, which causes the power steering pump and power brake pump to fail. This symptom of shutting off while driving creates a significant life safety risk for the driver, passengers, and other motorists. The vehicle has been inspected by the dealership over 4 times in 3 months. Since the vehicle shuts off, there are no warning lamps, messages or other symptoms prior to the failure.

My car has shut off multiple times , electrical shorts, intermittent no start, intermittent misfires all the time but randomly , injector codes even when replaced and injectors are good , yes come check out my vehicle no shops can find out what's the problem practically the whole front end has been replaced and problems still happening it is congruent with a recall but shows nothing from VIN.

Catalytic converter was defective in October 2022. Had to wait to get part in. Vehicle taken to dealer for repair in December 2022/ told that the second catalytic converter needed to be repaired. I stated that I was not aware that cars had two catalytic converters. Parts were ordered and replaced. Engine light came back on-again October 15, 2024. Portable CO detector in car was beeping when engine around time engine light came on. Not covered by warranty or insurance. A new car with 55, 000 miles to date should not have these issues.

Vehicle would not go into park fortunately we were in a safe location to avoid a possible accident or injury. The vehicle has electronic transmission shifting. According to the dealership the park solenoid in the transmission valve body failed. This prevented us from putting the vehicle in park so it could safely be shut off. We were able to set electronic parking brake but ignition continued to remain on. Eventually had to disconnect the negative battery terminal. Had vehicle towed to dealership but could not release electric park bake or start vehicle with battery terminal reconnected. This is becoming a common problem with this transmission, so common that parts are on back order. This could be a very unsafe problem with this vehicle in the right circumstance. There should be a recall on this transmit that is used on multiple gm vehicles.

It’s an absolutely unreasonable period of time to fix an airbag defect, I don’t feel safe at all driving this car. What is the government doing about this?.

After filling up fuel, vehicle runs rough, hesitates, and stalls at idle speeds. This occurs after every fill up. The check engine light comes on and states an issue with the anti-lock brake system. I’ve had the vehicle checked by Buick 5 times and they have not been able to replicate the issue, so troubleshooting stopped. I know a recall came out this July for 2019 Buick Enclaves to replace the evaporative emissions purge valve due to not fully closing. This is the issue with my 2020 Buick Enclave and is a massive safety concern as the vehicle stalls while driving at slow speeds after fill up. Most recent event occurred on October 5th. I’ve posted a picture from last year that captured the same issue.

I purchased my vehicle in 2020. In 2022 I experienced an issue where my car stopped in the middle of the road without warning. Despite several attempts to try and move the vehicle off of the road the police were notified and my vehicle was towed. The vehicle gave an error code that conditions not met for driving. One office tried to put the vehicle in neutral but the wheels locked and the shifter was locked as well. The battery has been replaced 3 different times since I have owned the vehicle. A mechanic friend of mine (who is a trainer for GMC) hooked his computer up to it and found no issues. He did find a loose wire which he the reconnected. I was able to drive my car for 6 months before the same thing happened, same situation the vehicle just stopped in the middle of the road only this time I couldn't turn the vehicle off, we had to manually disconnect the battery and again the police came out due to traffic hold up. My car was towed twice afterwards as I could get the car running for a few minutes before another error. To date my car has been sitting in my driveway since March of this year, this time it won't hold a charge and will not even start. Im not sure if this is an engine or an electrical issue. I did call 2 Buick dealerships that told me that it would take about 5 hours to diagnose the issue where I would be charged per hour at the mechanic hourly rate. At this point I think my vehicle needs to be recalled, even if I could get it repaired I dont feel safe driving it. Thankfully it stopped on a minor freeway and no major incidents occurred.

I took my Buick Enclave into the GMC dealership two years ago for an service airbag light that kept coming on. They sent me home twice saying it was just a computer issue. Now this recall is out and I asked for my car to be serviced as I’m a mother of 4 and can’t stop driving my vehicle. They said that the part isnt out yet and nothing they can do. I’m having to drive a dangerous vehicle around with no help from GMC.

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.

We purchased a 2011 Buick Enclave for what we thought was a great deal. We were prepared to pay for basic maintenance right after purchase. The check engine light came on as we were driving on the highway. I noticed loss of power while on cruise control(set at 65mph) and the vehicle started shaking. I noticed the rpm jumping from 1 to 2 . We took the vehicle to Buick for repairs. We had a tune up, 2 catalytic converters replaced, 3 O2 sensors replaced along with one other one that I'm not sure the name, oil change, struts and shocks, rear sway bar links, air filter, and a gasket manifold. We have not had this vehicle longer than 2 months. The vehicle is still doing the same thing. Today after we picked it up from the shop(no check engine light) we drove it on the highway and now the service traction control light is on along with stabilitrak control. We have 6 children. This is dangerous. What are we to do?.

Buick not a year old, in our garage very strong odor of gasoline cannot let it inside the garage it smells strong going into house attached to garage!.

My Enclave gets thre worst gas mileage of any vehicle I've ever owned. My 2003 trailblazer gets better gas mileage than this SUV by almost double and it's not very fuel efficient. My boyfriend's v8 silverado also gets about 50% better gas milage. Ive brought it in multiple times and they keep saying they can't find an issue bc the computer isn't flagging any issues. The driver side shock that wad replaced has also already went bad with no reason and the passenger side wheel wobbles when reversing out if a parking space. This again was checked and they denied finding any issues. This has been ongoing since I bought the vehicle and the ridiculously priced and worthless additional warranty in December of 2017.

Timing belt issues at 140000 miles should covered since it's a known problem.

My car was repaired by a dealership in texas. First they said it was a fuel injector. They replaced that. Then they said that that didn't work so they said I had a cracked head. They replaced that. I brought it home to shreveport, la. And it had gas fumes coming of of the a/c vents. The dealership here in bossier city that they put in a broken part. They supposedly fixed the problem. I picked the car up and it still had gas fumes. I took it back. They smelled it. Kept it for 2 days. They couldn't find the problem so the kept driving it and running it until they couldn't smell it any longer. I picked it up again and I still smell it. I brought it back but they are denying that they do. Even lied to gm customer service that they rode around with me. I had a horrible headache when I returned home with the car. It's been parked for over a week. I am terrified to drive it scared it will catch on fire or my children and I will get sick. Please help me. I have tried working with gm but they are no help. They give me the run around. The mechanics have also lied so many times regarding my car to gm customer service. I need someone in my corner. I haven't been able the drive my car sine 5/16/2019. It went to the 1st dealership on 5/18/2019. I drove about a total of 1. 5 since.

The car started dying whether I'm on the highway going 65 or stopped or accelerating. . . So many different circumstances. . The car will be going along fine and all of a sudden it says traction control off, service stabilitrak system, engine power reduced and then it dies. . . It does all of this in a matter of 3 seconds then I'm left trying to steer with no power steering. This has happened probably 35 to 40 times in the few months that I have had the car. Yesterday was just the last time.

I bought this vehicle July of 2017 probably about 6 months driving my radio makes a loud static noise and then no sound not even blinker sounds. I get in it later that day crank it it's fine. Then begin to have intermittent cranking issues crank it nothing everything on the dash blacks out nothing nothing happens turn the key back turn it back over it cranks that still seems to be a problem it still does that. Then a few months later my liftgate just opens by itself that has happened on several occasions I just been wake up in the morning the and the liftgate is open. One morning my husband wakes up to go to work and goes outside my car has actually remote start itself I was just sitting in the yard running like somebody remote started it but no one was up to do that. At night when I go to bed I don't lock my vehicle because I'm afraid it may be auto started the next morning when I get up and now my check engine light is on with my service traction control and service stabilitrak light the engine is giving the code for injectors 2 4 and 6. P204 202 206. These lights will randomly come on and go off and when their own the vehicle won't start bog down and try to cut off or cut off it doesn't want to stay running came to a red light three days ago those lights come on in the middle of pulling off from a red light it was green so I was pulling away car just shuts off put it put it in park crank it up drives right off.

Since I bought my 2010 Buick I've nothing but problem after problem. . For some reason the check engine light always seems to come on, suspension makes noise, and steering system is making noise. .

Takata recall. My park assist radio and all other sound when completly off I went to the store everything was working fine on my way there. When I got back in the car and turned it on nothing turned on.

Was driving on ramp to enter highway, with my three 6 and younger children, and also 7 months pregnant! the Enclave just stalled and still can not start but one time it did, but it sounded like it was going to blow up making weird noises so I shut it off right away. I have been researching this and I see it is very common with 2009 & 2010 Enclaves. I don't understand why nothing has been done? if this happened shortly later I would have been on the highway and several people could be involved getting hurt or killed. I have had it less than a year, with less than 104,000 miles on it. Also has wheel bearing issues which I replaced front now the rear ones need to be done. What is up with this neglect and no one to assist us consumers until someone gets seriously hurt or killed! now the vehicle is sitting at a garage where towed waiting for report and I have no vehicle so lost my job I have four kids to support. Figured I buy a newer decent vehicle to be dependable & reliable only to find out it's neither only unsafe for my family.

The check engine light keeps coming on after having smoke tests done and the error message is always tighten fuel cap. New original GMC part fuel caps have been purchased and numerous smoke tests have been conducted. When I'm driving out of the nowhere the error message tighten fuel cap comes on.

On Thursday, 7/26/2018, I had parked my car in a restaurant parking lot. I appear to have pulled the vehicle up onto a concrete space divider. When I tried leaving the restaurant, I couldn't back off of the space divider, the car wouldn't move backward, so I tried pulling foreword. When the car came free from the divider, it shot foreword. Applying the breaks had no effect. In fact the car appeared to accelerate. I was headed directly toward a concrete building, so to avoid hitting the building head on, I had just enough time to turn the steering wheel slightly causing the vehicle to side swipe the building but it crashed into two parked vehicles. It caused extensive damage to my vehicle and one of the parked vehicles and only slight damage to the third. It appeared that the vehicle accelerated beyond the effort I applied to the gas pedal, it ran away and the application of the brakes had no or little effect in slowing the vehicle. Is there, or has there been, reports of similar problems with acceleration problems with the Buick Enclave, 2015 model ?.

When filling up the vehicle with gas, it is flooding the engine. . . There is also another issue that when you turn off your vehicle and the key is out of the ignition, the car and radio still runs. . . Apparently, there is a fuse box that is causing this problem.

The fuel mileage reader is not working properly. . . Sometimes when I get gas it registers more mileage than it should. . . . Such as it may be on empty and the amount of fuel that I put in it should register that I would get 115 miles off it. . . . But it will register that I should get 150 miles. Sometimes it registers right and I can drive only 10 miles and the number of miles that I can travel will drop by 28 miles or more. It changes as I drive but doesn't show the proper mileage left as be appropriate. Also my heat is only coming out the vents in the rear and the top side dash vents and the bottom driver side floor vent. The front dash vents have no heat and the bottom floor passenger vent is blowing cool air. The heat problem is when driving and siting. The mileage reader is occurring when driving and after refilling and sometimes while sitting with the car running.

Fuel indicator is all over the place. Drop to zero and to half and full and back to zero.

The vehicle stalls during acceleration at about 1800 to 2200 rpn, more often after a stop of vehicle and is more noticeable at low speeds from 20 to 50 mph in both city and highway but more often in city streets, increasing the risk of a crash. No engine lights come on so mechanics are telling me that they can't diagnose without any codes on the engine. Vehicle has about 100k miles and this failure started about 95 k miles and getting worse with time. So far the engine has not shut off.

Brought the car in earlier this year because the car was stalling. They told me it may have been a lose cable, but likely was nothing. In the last 3 weeks the car has stalled 3 times with my kids in the car. I brought the car in 3 days ago and they looked at it and said nothing was wrong with it. Yesterday it stalled again and my wife came very close to getting rear-ended with the kids in the car. This is a car that is 1 year old with 5. 500 miles on it. This should not be happening and the car company is not helping me with this. Help!.
