Engine stalls/quits while driving!

I have an 08 Enclave CXL, 45k miles -- purchased new, no accidents or major issues ever (minor issues, yes).

This has happened to me over the last month, 4 times. Random times, various speeds, while driving I lose engine power but not electrical power, so I don't know I have a problem until I try to steer or accelerate. No warning lights sounds, nothing. I took it to the dealer and they didn't find anything wrong, they fixed a braking system malfunction and was hoping it was somehow tied into that. But the next day after getting my car back from them it does it again. Today when I took it in, the foreman actually drove it with me and it did it AGAIN (thank goodness because you know it NEVER malfunctions when they are behind the wheel, lol). He is completely dumbfounded and has never heard of this happening -- the strangest part being that no warning lights come up on the dash so that they might have a "trail" to follow to find the source of the issue.

Also, once this happens, it can be restarted immediately with no problems. In fact, after it stalled on the foreman, he shifted into neutral and restarted it while coasting.

They have it now and are going to drive it with some sort of device that is supposed to capture an image of the system, should it do it again.

Has anybody ever experienced this or know somebody that has? It has me very worried and paranoid about my safety, my passengers' safety as well as other motorists out on the road.

I am sure Michelle will help you.

BUT you did not like kidsenclave's response nor did you appreciate what ccaats said and I am pretty darn sure your comment back to me....well let's just say I didn't appreciate it. AFTER ALL you did not inform anyone as to what part of the country you lived in and you totally dismissed those of us who believe the previous water leaks may be an issue with your vehicle.

You see we, the members who have been here way longer, have a lot more experience as to what may be happening with your vehicle. Oh and that includes me having dealt with water leaks and how sneaky they really are getting into everything from the front to the back of the vehicle.

I believe you said that is why you joined and posted your question and you were given some real opinions on this.

As for any questions you may post down the road.......

Oh and have a great day. ;)
Do you realize what you are doing? You are making up the "tone" in which I write things. That's the problem with interpreting text only. I am sorry that I don't write more descriptively, my comments were never intended to come across the way you interpreted them, especially to you, because honestly you didn't say anything out of the scope of the issue at hand. I understand there are others who obviously love their Enclaves, but in the middle of finding answers to an extremely serous issue (my children are usually in the car with me!) it isn't helpful to hear anything other than problem solving.

I doubt I will post any other questions on this board because I will be trading in/or selling my Enclave as soon as possible. I hope that all of you with Enclaves continue to be problem free, because I wouldn't wish anybody an engine stall at 65 mph on a busy highway, with kids in the car. Good sense and reaction has to overide panic and sometimes that is very difficult. If my tone is interpreted as anything other than sunny and positive, it is justified in the middle of this virtual nightmare.

In no way do I believe the OP should have been called out about mentioning how dependable the Infinity has been compared to the Enclave. Heck, they've had the water leak and battery problems known to happen on the 08 Enclave.

They've had a master cylinder leak into the brake booster. Now they have an engine which cuts out while driving for no reason. They have just signed up on this forum to get help or answers, and they are attacked for mentioning something about a car that hasn't given them near the problems that the Enclave has.

Do people really think posts are being made about one subject all of a sudden just to bad mouth the Enclave? What benefit do they get out of that? You should be able to tell if it's a troll posting, or someone really trying to get help.

Whoonuu, welcome to the forum, and I hope you get your problems resolved. I hope you stick around and can learn about your Enclave from these forums. :thumb:
Wow. Somebody reported me? This is ridiculous, absolutely crazy.

Thanks ls973800. I appreciate your comments.

Some ideas for posting about a problem: First off, like going to the doctor's office...be real, and tell us the details of your vehicle, year, miles, and past repairs. (you never know what might be a past problem causing something new) Also, mentioning your location and climate is a plus too. (like Sailfish pointed out) Now, on to how this forum works....it's not just about someone only commenting that has solution, sometimes it's about just chat that may or may not lead to a solution. I brought up other threads about water leaks, and low and behold...you had one in the past, so me just rambling brought out a possible cause...something you can share with the dealer which might lead to the root cause, and a solution. (not trying to over embelish what I said...just point out that in this case, it brought up something we didn't know, your water leak). Just saying, don't dismiss a post that seems like rambling to be of no help to you, it may be surprising to find things out when people are just chatting on here. Next, the blanket statements (and I've been guilty of this in the past) where you say something like "I would not recommend to anyone that they buy an Enclave. Looks great but is completely unreliable." is saying that ALL Enclaves are unreliable, and that NO ONE should buy one. Also, comments like " I wish it would blow up so I didn't have to be an Enclave owner" are statements that don't go over very well, especially since you are talking to Enclave owners here....just saying.

I totally get your frustration, but just because of that doesn't mean tact goes out the window when seeking help here.

Michelle should be of help to you, and when it's all sorted out..let us know what she and the dealer finds out, because regardless of the back and forth comments, the real topic here is to help each other....and with a cause noted when all said and done, that will help the rest of us to know what to look out for and/or to alert our dealers if this ever happens to us.

whoonuu your correct the written/typed word does not portray the inflection of our tone of voice as it would if we would speak the comment. (edit: because then you would hear my southern drawl....and I am a Yankee born and reared up here in Ohio...with a few years in the Bible belt of Tennessee)

That is why I generally try and use the "emotions" to reflect my intent. If the tone of my writing does not have humorous "emotions" as in smileys or winks then one can presume that I am not in a light mood at the time I write/type anything.

So again...have a great day. ;) ;D

Update:

Replaced ECM (Engine Control Module). They think that the fact the engine stalls with no warning alerts/dash lighting up PLUS the random battery problems (car won't start but accessories work -- and yes I mentioned battery problems in a previous post -- when mentioned twice to the tech he didn't think the two were related, now he does). Hoping this is the right fix, if not will post more updates for any lucky persons that find themselves in the same situation.

My husband is still afraid for me to drive (and I am not a wimpy female, I think it has more to do with children) so we will switch vehicles, no name brands mentioned, until comfortable.

None of us can really know for sure, but my hunch is you'll be ok. If it makes you feel better, take the car out early when there's no traffic, and test it, over a period of time. I've been through this with the BMW--they had the car 3 1/2 wks., tore all the carpeting out and removed the seats, tracing the optical cabling, and when they were stumped, they replaced the DME per the mfg. (that's what BMW calls the ecu, like Coke is cola, etc.). It's great that GM is willing to replace that and not make you jump through hoops. BMW is not willing to replace things without proof, there's no we think it would help so go ahead, which I think GM is willing to do. I looked it up and an Enclave remanuf. motor is like $4400. A 335i motor is like 11.7k remanuf. So I think it's very feasible for GM to just replace without knowing the root cause, and that's good for us.

And the random battery problems make common sense to me. I have witnessed on the BMW the orderly shutdown of accessories when the battery was weak--heated steering wheel, rear defrost, bluetooth dropping, reconnecting, dropping, heated seats, etc., all of which are considered non-essential (though defrost could be depending). ABC news did a news story on the BMW N54 motor, so if it were that serious, I'm sure they'd do it on Buick too if it were warranted. But I doubt it's widespread, just poor quality maybe in your case. But the part has been replaced. Good luck!

For future trouble-shooting seekers, I want to post an email that I received from somebody yesterday -- similar problem -- if I get any updates from this person I will post it or possibly start a new thread for him. As for me, my Enclave is currently at the shop over the weekend (no surprise there) for continuing battery/starter issues. It fails to start at random times, will sometimes start after several tries. Haven't driven it a whole lot as my husband surprised me with a new luxury cross-over (no Make mentioned, delicate subject around the board) but the engine stall problem appears to have been resolved, fingers crossed. Plan on selling it as soon as we resolve the current problem. I am on a first-name basis with the foreman now, he seems like a very competent person so I am sure if anybody can figure this problem out it will be him.

Here is the email:

Here is what happened to us in our 2010 Enclave with 14000 miles last week. My wife and I were on the first day of our 4800 mile trip to Az. We were going to KY for Thanksgiving then onto to AZ for 3 weeks. We left lower Michigan and about 300 miles into our trip this is what happened. We were driving with the cruise off due to heavy traffic. I was in the middle lane of I-75, north of Cincinnati at 65 mph. The tach suddenly went to 4000 rpm (est) and then down to under 800 rpm. We lost power and coasted for a few seconds. It gained power again and we safely got into the slow lane and drove slow (50mph). It happened once more so we pulled off a side road. All seemed good till we went to merge back onto I-75, same thing at a slower speed. That is when I pulled off and called GM roadside service. We continued back about 14 miles to Kerry Buick/GMC in Cincinnati. No problems on the way there. This was the day before thanksgiving and we were worried about getting service. The Servive rep took us right in. Gave him the story and he took my keys and headed out for a 8 mile trial drive. Then checked for error codes and saw none. We were back on the road within 40 minutes with nothing being done. Not much they could do I guess. We continued on with worry of course. Made it to KY and then onto AZ. We had no trouble what-so-ever in the next 2000 miles. Hope all stays good, sitting on the side of the freeway is not fun, and in the middle of nowhere in the I40 freeways in OK, NM and Texas would suck. Nice cmfy ride and with 22.3 mpg in a vechile this size is great

Picked up the Enclave yesterday after days in the shop, they were waiting for the battery to act up, which it never did "for them". Well today guess what? It failed to start twice AND, here's the kicker, it stalled on the way home from work, while driving of course.

Looking into filing a Lemon Law claim.

whoonuu,
I would like to apologize for the frustrations and inconveniences that you have been experiencing with your Enclave. I would like to look into this for you. I am going to send you a private message to gather more information from you.
Thank you,
Stacy Buick Customer Service

Knock on wood I hope none of us experience what you are, but I have had the same experience as you're having with another make, and the problem was ultimately fixed when I started to transform from a spineless jellyfish to Donald J Trump. Not being able to find anything is unacceptable, because either you're making up the fact that the vehicle stalled, or there is something wrong with the vehicle. Maybe they should loan you a new Cadillac CTS-V while they fix your Enclave. No fix, no Cadillac back. Let's see how quickly the problem is solved.

Nobody should have to pay hard-earned money and wind up with a vehicle they cannot even drive. That is unless you have a spare 40k in your pocket, in that case, just buy a Pilot and be happy for 10-15 years and be done with it. :thumb: Good luck.
 
#39 ·
Thanks john -- No, trust me, no spineless jellyfish here! LOL My husband and I are staying on top of this.

Currently the problems were discussed by Engineering, they believe there is something wrong with losing voltage, something to do with the starter -- both the battery issue and the engine stalls point to this (they say). There are three parts on order for this monday. I will post more specific details once I get that information on paper.

On one occasion the vehicle was picked up directly from our driveway so they know we aren't hurting: they saw my new car, my husband's car and my son's car -- but I haven't asked for anything. I will be completely happy if they just fix that darn thing!

I just googled "Buick Enclave stalls" and found this forum and thread. My wife has this exact problem. We have a 2008 Enclave with 65k miles. Hers stalls while driving and also won't start at times. The not starting happened to me once. I pulled it out of park then back in. Fired right up. When it doesn't start it's as if the battery is totally dead but that is not the case. The bigger issue is the stalling while driving. Scared her to death. It just came out of service where they said there was a TSB on this issue. No problem, it was fixed. Not so fast. It came out of the shop on Monday and wouldn't start on Wednesday. It eventually did. Today (Thursday) is stalled while she was driving and wouldn't fire back up. Towed back to the dealership to try again.

Our service department seems to be as lost as your service deparment. They will start working on it again tomorrow. I'll keep you posted.

I noticed a Buick customer service person has been viewing this forum and this issue. How can I reach out to you or vice versa? My wife wants to get rid of the Enclave ASAP. The stalling issue has happened to her three times and we have twin 4 year olds. Twice it happened while on a crowded highway at highway speeds. It scared her so much she doesn't want to drive the car at all at this point. Any assistance greatly appreciated. We are really not in a position to get a new car nor can I afford to rent a car until she's satisfied that it's fixed. We've really enjoyed our Enclave and it's been perfect for our family. However, this is a obviously a big problem.

Our 08' Enclave is at Ritchey Cadilliac/Buick in Daytona Beach. Bruce is our service manager and is the one trying to help but doesn't seem to know what to do. He said that no one else has this issue.

Please help, thank you!

John

You can sent a personal message or tomorrow the CSR should be back online. She is usually only on during the week and perhaps one Saturday a month.

Boy do I feel your pain! Please check through every post of mine for the details of each repair. Eventually ours was fixed (we have already sold it THANK GOD). the very last thing they did was replace the ignition switch.

I would forget contacting the Buick service people who post on this site -- I registered with them and they did absolutely nothing for me other than call to see if the problem was fixed. Everytime they called (they had what seemed like clerical people calling) I would tell them "No, problem is not fixed" then *I* would ask them several questions and they never were able to give me an answer on anything. Was crazy and a complete waste of time.

This is what I suggest: Have your service people call mine. All of the repairs were done at Cavender Buick GMC in San antonio, TX. Phone number 210-490-2000. The Shop Foreman, name is Robert Hinton, was the one leading the charge on this and eventually solved the problem -- took him several tries but he was very diligent. Very impressed with Mr. Hinton. He is bound to remember this as he was completely stumped. The stalling even happened to him the first time we took it out for a drive. Tell him it was an 08 CXL (red). If they need more info, like the vin, I can send it to you privately. Just let me know.

Good luck! I know what you are going through -- it is scary as ****. One thing Robert taught me is that once you are done freaking out, you can put the car in neutral, turn the ignition off then restart the car, all while it is moving.

This is a very good piece of advice!!
 
#45 ·
all my cars can be started in neutral..
Actually I can start my 1970 Chevy Monte Carlo in Neutral too....
Traverse will start in neutral...

Its also in the owners manual.


Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
 
#46 ·
I am sure most vehicles will start in neutral but I offered this information because when you are traveling at highway speeds and your engine dies, it is extremely frightening as control of the car becomes almost impossible -- so if you are going into a curve, you can forget staying in your lane. If this happens to you like it has happened to me and this other person now, you are in PANIC mode -- restarting the car while moving was something that never occured to me, mostly because I am in that panic mode when it happens.

I really hope this person gets their issue resolved! I wouldnt wish these circumstances on anybody!
 
#47 ·
I hope this is resolved for the owner. On the opposite side...we had a Honda that would randomly go full throttle. Happened a couple times and Honda couldn't figure it out over a couple months. Last time we drove it was the scariest drive ever... to frame it....Ever see one of those TruTv with a car weaving in and out of traffic out of control.... that was me one time on a semi-crowded highway with wifey and 4 kids in back...the car wouldn't turn off with the key either.....Never drove the car again...Thank god no one was hurt...

It is scary as **** to be in an out of control vehicle until it is stopped.

Awwwwww... It's a lot more fun to jam it into Park at 65 mph!! :happy: :happy: :happy:

Sounds to me like any new vehicle that's so computer controlled has the potential to just shut down. Guess if we want to avoid this, better buy a 10yr old used car. I totally agree it's scary, but I'm sure it can be fixed.

Thank you so much for the info about your Enclave. I spoke to our technician earlier today and he said they KNOW what's wrong and will have it to us on Monday. He said it is a Body Control Module. Later in the day I sent him the VIN number or your car with the information. He called me back within a few minutes and said they pulled up the car in their system and could see what was done. He said they replaced a number of items over a period of weeks. The last thing that was replaced was theeeeee...Body Control Module. It was helpful to our guys that the car wouldn't start while in their shop.

I'm assuming this will fix the problem based upon the other car. It obviously give us enough confidence to drive the car without the fear.

Thanks again. I'll report back in a couple weeks assuming it works out. Until then, think Body Control Module when your Enclave won't start and stalls in traffic.

I don't understand what prevented you from just shifting into Neutral when this happened??
Disconnect power to the wheels, let the engine rev while coasting to the sholder. Any automatic can be shifted into N and it will just coast - certainly better than endangering everyone on the hwy while the unentended acceleration is ocurring. Even standing on the brake pedal with both feet would have some impact on slowing the vehicle and be better than hanging on to a run-away.

Please explain why a neutral shift could not be done as this could possibly happen to other vehicles and everyone should be aware of what to do should it happen to them.
