I had the problems as described in ID 14S17 back in November. I had my vehicle in the dealer a total of four times. The only way they were able to get the issue to go away was by replacing the entire engine wiring harness. The fix now is likely less drastic, but my dealer was desperate. It threw all kinds of codes, engine surging on the highway, no torque when getting on the throttle, and engine stalling. Since having this fixed I have had no problems with the vehicle.

Exact thing has happened to me two or three times, but has not caused me any trouble.

No. Does the Cadillac XTS share the same base engine as the Impala? Hardly ever do you see a premium brand share the same base, or near base engine. If anything they would get rid of the 2.5L but even that is unlikely.

I want one.

Took the vehicle to the dealer today. They are going to order a "whole wiring harness" and replace it. I'm guessing it is just the wiring harness for the powertrain. I was told it is going to be a couple day job.

I had the entire TSB 13-7-5 done a week ago. A few days went by and seemed like all was well. Then I started up the vehicle and had the same message you speak of, "Engine Fault, Service Now". Like you said, it goes into limp mode. Turned the vehicle off and back on and it was back to normal. I also have a surging and lack of engine power symptom that does not throw any codes or anything. I don't know if it's related, but the symptoms were identical to that described in the TSB. I'm very disappointed the TSB didn't fix either of the problems. When it happens again I will be driving it to the dealer without shutting it off to get it diagnosed. Problem is I am done at work at 4:00 PM and it typically takes an hour to get to the dealer, which closes at 5. Frustrating.

Same light as the Focus?

Sadly it does not.

Can you provide a picture of where they sealed it up?

So I talked to my dealer and they are ordering the parts per the TSB. The last couple days the vehicle has turned itself off twice when braking for a turn and a stop. No idea what is going on here now, and I don't know if the symptom is at all relalted to this TSB. As soon as I get one issue figured out something else pops up. Other issues: 1) Radio and music through Bluetooth do not function and buttons are not responsive and does not output sound. When this happens the reverse guidelines also turn themselves off. 2) Whistling noise coming from front driver side. Only when temperature is below 60 degrees, a little bit of wind, and driving over 50 mph. I've taken the roof cross bars off and inspected all the weatherstripping around the door. 3) Popping sound on startup, as described in other threads.

Finally! This has been what I've been waiting for for 3 months. Been to the dealer two times already, and would have gone a third time last week Friday, but all four dealers within 50 miles could not diagnose it (no technicians after 4 PM). The engine fault, service now message goes away after the vehicle is restarted, so I turned it off and on and it was normal again. Exactly what I have been dealing with.

You're right. Apple probably does this on purpose because they knew they would be trying to do their own phone and car integration. Easy way to get better adoption if your competitor can't do a comparable feature. MFT has been good in principle, but execution has been poor. For instance, why does it sometimes take 10 seconds to index on the music on my phone, and the next time it won't complete the index? Unplug and plug in the phone multiple times to get it to work. Not to mention MFT has completely locked up twice and is impossible to remedy without restarting the vehicle multiple times. "Kids, the radio quit working, let me pull off the highway so I can turn the vehicle off and on". I bought the vehicle more for the fuel economy, engine output, aesthetics, and convenience features more than MFT.

Sending text messages by voice.

Nothing too spectacular, just things that should have been right since day one. Better phone pairing, easier voice commands. I'm not going to hold my breath on iPhone texting.

Very similar condition to what I have been trying to get diagnosed. I've had a MAP sensor code and an "engine fault, service now" is the information display. The two times I have taken it in to the dealer they have not been able to find anything wrong. In my case I doubt it is transmission related, but engine instead. When acting up however, it does behave very similar to what you describe.
