2014 Cruze LTZ surges on the highway - service has the car for over a week!

My 2014 LTZ developed what seems like a misfire when accelerating on the highway in the 2k - 3k RPM range. I took it into the local Chevy dealer, and they said it was a bad spark plug. They replaced the plug - but the problem was still there. They then replaced the ECM. The problem was still there. They have had the car for a week now - and still can't figure out what the problem is! I have a new Malibu as a courtesy loaner - but I miss my Cruze! A week with no resolution seems pretty lame (to me anyway), right?

Whats the temperatures been like in your area? When above 80F outside the cruze will run much smoother with premium fuel(turbo car). My car will even misfire enough to be audible and visible on the tachometer blipping/dropping under acceleration..... My car only gets premium now so I never experience this.
It will probably run better, but I think the 2014 has a ECM tune that allows it to run pretty good on regular.

What I didn't see was a coil replacement.

And yes, I'd think a week is excessive.

I do running premium (93). I suggested they replace the coils when I talked to them mid last week. I called them on Thursday, and they said they are still checking the car out.
That is, I AM running premium.

Hi Andy,

I can definitely understand your frustrations with this! If you need any additional assistance with this, I would be more than happy to look into this further as well. Feel free to send me a private message along with your VIN, current mileage, contact information and preferred dealership.

Finally, the dealer said it was a bad mass airflow sensor, which burned out the ignition coil. Hopefully that will solve the problem! Ill test it out tomorrow.

Yeah, seems nuts to me, and, I think the car is STILL slipping/surging. HAS to be the transmission, or some other engine part other than a spark plug/ECM/or MAS!? If it's still doing it, I have to find another dealer.
Same thing is still happening. Sending a Lemon Law letter to GM!

Poor diagnosis does not qualify (yet) as a lemon.....I like your first idea....find another dealer.....take them for a road test and demonstrate the concern.

Lemon law is pretty clear. 3 attempts to fix a problem without resolution. Done.
Update: Finally, the dealer proved me 100% right from day 1 - they say a broken snap ring in the transmission caused the clutch to slip - eh! That's what I was complaining about all along - a tranny issue! They have to take the transmission out and see what's what in there. That should solve my problem instead of: spark plugs, ignition coil, MAS.

Congrats on getting the dealership to figure it out. Did they give you an estimated time to repair?
The dealer called yesterday saying the are replacing all the transmission's "clutch packs"? They said they also have a GM engineer on the way out to check on it because there is another Cruze in for the same problem. Awesome. I'm driving a Malibu until they get my car fixed. Joy.
Did your Cruze ever throw a check engine light? My 2014 Cruze is doing the same thing, has been for the longest. Notice it everyday I go to work, set cruise control to 75mph, about 2500rpm area and I feel the car surging. I can even watch the tachometer dip up and down while surging is happening.
