2009 Chevrolet Traverse: misfire or rough idle

Filed Jul 22, 2020 · Electrical, Engine · 136,000 miles · IL

I keep getting multiple random engine misfires that there seems to be no solution to fix the problem. The vehicle has been to the dealership several times. Runs for a while and starts acting up again. Stalls out when attempt to take off after coming to a stop or just starts to move and goes real slow, also has trouble getting up hills due to loss of power. Keep getting told it's catiloc converters and have replaced 3 times in last year. Have also replaced spark plugs and coil overs as well as fuel pump, mas airflow sensor, map sensor, oxygen sensors, and a few other things. Seems there is a lot of people with the same issues but no fix....

"takata recall" while driving on i70 south in the fast lane my 2009 chevy traverse started to loose power, lights started flickering, and then ultimately stopped as I was partially in the roadway. State patrol had to come out and move the vehicle and assure my safety of exiting on this very dark interstate. The vehicle would not even start up again. And this was three days following a tune-up w/6 new coil packs, oil change w/filter and flow vent. And all this cost almost 600.00 bucks because coils are nearly 45.00 per coil. And all this had to happen because of a constant misfire in all of my cylinders. So I had the truck towed 48 miles home and then 16 miles to the dealer just to be told that this truck has a timing chain recall that was never done. So I was told by the dealership to call che y corporate office. Lol. Chevrolet told me that the the recall expired and that I would have to pay for the timing chain myself. After 2 years of constant spending. Im done and have been advised to sue. The trooper called to follow up with me because I did almost die on the interstate because my vehicle went completely out and 18 wheelers were going extremely fast. And he provided me with a complete police report to go after chevy. My two kids now hate the vehicle. My daughter cried all through the 4th of july because of the trauma. And chevy should not be allowed to sell family vehicles without having a families safety in mind. This was my first chevy purchase and it will be my last. This is not a company I wish to support. Because it could careless about our lives and safety. I refuse to pay another 2k to repair an issue that had a recall that I didnt know about. #2ndownersclub

I have been battling my check engine light all 2018 and now 2019. Not to mention the stabiliztrak and hard to turn steering wheel. I have been getting a misfire in all my coils. This issue has caused the vehicle to stutter, drink high volumes of gas and almost sent me broke. I have changed every coil, every plug, changed the stabilizer, tentioner, bearings, swaybar links and much more. I am completely done with chevy. They know this make and midel is horrible and we as customers need to do a class action lawsuit. This vehicle sounds like a tin can when it starts. It rattles and stutters while driving and it shakes when stationary.

My 09' traverse started to shudder intermittently on acceleration and then the service engine light (sel) came on. I had the car diagnosed and the code was a p0302 (misfire cyl). I had the car serviced and repaired by an ase certified mechanic. All coils and spark plugs were replaced along with fuel inj service, performance restore (oil, gaskets, etc). No discrepancies were noted with previous coils/plugs. The car appeared to be fixed. No problems were noted during an 800 mile roundtrip. Then the shuddering returned during normal day driving around town upon acceleration with the sel illuminating. I took the car back into the mechanic, and the code was the same (p0302). After further research by the mechanic, a gm technical bulletin was found (#pip5038b). I've contacted gm customer service and filed a complaint, case # 9-5063655170.

Our check engine light came on and our vehicle started misfiring after we took it to dealer and they fixed the airbag codes so the air bag warning would go off. They said they had to change the wiring in the engine too not just between seats. We replaced all six plugs and 3 coils that the codes said were misfiring. Got it back and drove to georgia bout a 2 1/2 hour drive. Before we got there it misfired check engine light came on. We made it back on sunday but car started losing power and check engine light kept flashing. I barley made it to exit and had to stop at gas station across from the one her ride was at. Our friends got it pulled into a spot but it made weird popping noises and had burning smell with no power then at very end power kicked in and he had to slam brakes. I left car there and forgot to lock it so we drove back to see if my husband could get it back to shop. My husband was accelerating up on ramp and car jerked and died completely. He had to fight it over to emergency lane at top of ramp. Vehicle wouldn't start. Costed 150 to have it towed to shop. Shop replaced catalytic converters after about a week cause had to fig out what hap. Drove car couple weeks it messed up again. Shop redid the wiring in engine that dealership messed up and we bought gm plugs and 3 coils. Car worked a little bit messed up again. Tried to get it 75 miles to dealership and pulled over to have it towed 150 again because it was about to die completely again. Converters had to be replaced again. Car is messed up again. Husband researched it bad timing (which makes engine skip time and it had been jerking and lurching so probably is what broke motor mount) makes the coils send too much gas and insides of converters melt and block up. If engine dies completely at 70mph on freeway a bad wreck can happen this is unsafe and chevrolet should replace these engines.

Twice in the past 11 months I have had cylinder coil failures while driving on interstate highways at high speeds. The coil failures and resulting misfires caused a sudden loss of full power and a dangerous slow down in heavy traffic.

Numerous AC issues, dealer has never been able to repair.now we receive engine code stating the #4 cylinder misfireing. Before we can have it repaired the vehicle just quit. No power from engine, no brakes, all kinds of electrical sensors are giving alerts and car just turns off. Seems to also be affecting cooling fan and steering. Also ever since we purchased the vehicle has made a wierd noise in the front end. Dealer claims it was nothing and after warranty expired we took it in for AC again and was told the front struts were needing to be replaced along with all kinds of AC parts. How come this was never mentioned until warranty expired? I am so tired of getting ripped off with vehicles. Had issues with ford, dodge and now gm. Guess its time to try an import?

Driving on a highway went to change lane. While accelerating the car started to shake, buck and slow down. Engine light came on. Brought it to the dealer found intermittent code p0306. Performed emission service. Happened again 60days later. Back to the dealer found code p0305 and p0306. They cleaned spark plugs. Happened again 30 days later. Back to the dealer. Codes p0300, p0305, po301, p0304, p0306. Onstar diagnostics: cylinder misfire, engine misfire. Back to the dealer. Soak engine with gm cleaner. Happened again 1 day later. Back to the dealer. Same codes as above. Dealer wants to do a valve job on the car. Waiting to find out what that will cost. Don't know when the misfires will happen. If am trying to pass another car on a highway at high speed and a misfire happens I am sure a accident will occur and it could be fatal.

2009 traverse purchased 4/30/2009. From the start it had a check engine light on but no symptoms of failure. We took it to dealer 1 on 9/02/2010, with 22,753 miles. They replaced wiring under engine plenum to #1 ignition coils. A couple of days later, the check engine light came back on. At this time the car started to lose power on the freeway sometimes. We took it to dealer 2 on 10/11/2010, they had to get parts and did a temporary fix. We brought it back on 11/1/2010, with 24,656 miles on it and they supposedly fixed it. They replaced connectors in the junction box, saying it was an electrical problem. The light was back on within a few days, and the car was still losing power. We took it to dealer 3 on 2/09/2011, with 30,287 miles for check engine light, and loss of power. They replaced ECM and all 6 coils. The day we left the shop, the light was back on and within a day the car was losing power again. Back to the shop on 2/17/11. This time they replaced the catalytic converter. The day after we left the shop the light was back on. They told us it needed a small adjustment and to bring it back on 3/05/11. We went to the shop and the mechanic did not know how to fix it. After being there for a few hours and calling chevy 800 #, they told us to come back next week. On 3/06/11, the car was losing power so bad that we wanted to take it back to the shop, but they were closed. On 3/07/11 the traverse started losing power, and then died. It lost all power and the brakes failed as a result. We had to slam on the emergency brake to not have an accident, and were lucky to not be rear ended. The car has been at the shop the week of 3/07/11-3/11/11. They told us the car is misfiring on all cylinders and dumping raw gas into the exhaust. On 3/11/11 they called to state that they are replacing the catalytic converter (again) and the module and returning the vehicle on 3/14/11.
