Taking my 12 Captiva 2.4 in for service Nov 22nd, having the following issues below, also wondering if anyone else has similar problems. 27k miles 1. Headlights and interior lights have started flickering at idle. Also when I turn on my blinker or depress the brakes, I notice my headlights dimming down for a split second. (I'm guessing a bad alternator or battery). 2. Volume control on steering wheel is very tight to operate / broken. 3. Drivers door intermittently will not unlock via fob or when putting the SUV in park. 4. all 4 Power windows sometimes will not go down. 5. Transmission 6T45(MH7) has always had a lot of issues. Eco mode on and off. A. Consistently stays in 5th gear going downhill for 10 seconds. B. When cold, slips between 1-2 gear badly, after its warm it seems fine. C. Rolling slowly in parking lots, between 1-2 and 2-3 it sometimes slams into gear and feels like I have been rear ended. D. Highway, sometimes kicks to 3rd gear revving 5900RPM+ for no reason. Turning off cruise control results in a very loud deceleration noise. It stays stuck in 3rd gear for 5-10 seconds then shifts back to 6th. E. Multiple times under heavy acceleration in the city, stays stuck in first gear, revs to red line, very loud deceleration noises, after 5-10 seconds it begins to shift and operate like normal. F. Setting cruise control at 72MPH right after a fast acceleration on the highway results in the suv downshifting to 3rd gear, revving 5900 RPM and staying stuck there for 5-10 seconds. Disconnecting the battery for 2 hours did not help; the transmission seems stuck on stupid, just plain bad transmission programming. Hope there is a software update that can fix it. 6. Belt chirps at startup, also chirps loud if the AC is turned on. 7. Engine idle is horrible, it’s always on the edge of stalling, the entire SUV jumps, rocks, shakes, jars passengers constantly at idle, feels like a 3 cylinder. I have complained to the dealer 4 times already and they say its normal. Passengers are laughing at me it idles so badly. Envision an gnome under the hood with a switch turning the engine off and on at random real fast, that’s my engine idle. (Maybe a bad alternator, timing chain or bad battery could be causing this?) I have tried a new air filter, new spark plugs at 15k, 8 bottles of chevron techron have been put through the gas tank, nothing helps the idle. 8. From a cold start, the engine chatters very loudly, sounds like it has no oil in it. Slow in a parking lot 1000-2000 RPM, louder on deceleration. Premium gas does not help, after it warms up it goes away. 9. Drivers window does not go up all the way while driving on the highway in high winds; it gets stuck in the molding. Reported this already, they put silicone on the molding, but it never fixed it. Nothing but trouble with my last 3 Chevys, not sure why I keep buying them, this one will likely be my last, and I may have to ditch it soon if GM does not support it.
