Xt5 start-stop – page 9 gas exchange in the lungs

For the past two weeks my wife and I have been driving a 2017 XT5 loaner (brand new when we got it) while our 2013 SRX Performance is in shop (getting a new engine). Having had a chance to compare the two I will not consider the new XT5 as a replacement for our current SRX. I don’t like the start/stop feature – many here say it is not obtrusive but it really is. There is a small shudder every time it shuts off and starts. In addition the transmission has a noticeable delay before engaging as a result. For a car of this class and cost, this is unacceptable. Also, this start/stop technology has to create additional wear and tear on starter and downstream components. I have read the comments on this forum and others that the starter has heavy duty components to handle the additional wear but, all things being equal, this starter will wear out sooner based on the additional number of starts that it must endure. Further, when it does fail – and it will utlimately – there is a good chance this will happen in traffic. That would at best be a very uncomfortable situation and at worst could be dangerous. I’m not opposed to new technology but it should be absolutely seemless before introducing it on cars available to the public. Our overall impression is that the 2013 is a much more luxurious and substantial feeling vehicle than the new XT5. As mentioned above, this will not be on our short list of SUV’s to consider as a replacement vehicle. After much good progress it looks like Cadillac has taken several steps backward with the XT5 IMHO.I beg to differ, I too had a 2013 SRX prior to get the XT5, in almost every aspects Cadillac improved the offering, lighter, faster, more connected to the road, more efficient and better looking. Its not perfect by any mean, but so was the SRX.

IMHOI’m not sure what you mean regarding your last comment but believe it proves my point. Parts fail. In this case a series of unusual events led to a catastrophic engine failure. Up until that point this car has been trouble free. Fortunately it is all covered by warranty. And by the way the XT5 has the same engine as the 2013. You say the car is lighter, my take is that it is less substantial. You say it is more connected to the road, my take is that it rides rougher and is noisier inside the cabin. I like handling as much as anyone but not what I am looking for or expect in this vehicle. When I want great handling in a lighter car I drive my 2014 Vette which is fast and connected to the road. It is also rides rougher and is noisier but that is to be expected. Those are some of the trade offs we make. In any case we are all entitled to our own opinions and I’m glad you like your new XT5. For me, I won’t buy a car with start/stop technology at least until it’s much better than at present and proven reliable over time. I can afford the car and am not concerned about the minuscule amount of gas saved through this technology.

And by the way the XT5 has the same engine as the 2013.For what it is worth, the 2013 SRX has the LFX engine and the XT5 has the LGX. There are a lot of differences between the two while they are very similar in displacement and they are both DOHC V6’s.

I also had a 2013 SRX which I liked at the time, but there are tremendous improvements in the XT5. For one, the transmission control parameters are far superior in the XT5 because it is always in the right gear whether accelerating or decelerating. I also have a 2014 Corvette which is my performance car when I do not need the roominess of the XT5.

I am pleased with the XT5 implementation of the start/stop while not thrilled that we will need to accept the technology no matter the make of vehicle we purchase in the future. The auto makers are steered in that direction because of the CAFE credits given by the EPA. In today’s environment every fraction of an mpg is worth millions to auto manufacturers. In the case of start/stop it is not even used in the CAFE tests, but credits rewarded for equipping the vehicles and more credits if the feature cannot be turned off.

Just dropped off a 2017 XT5 Luxury twenty-four hour loaner while the shop performs service on my vehicle. The ride and sound level in the cabin is light years beyond the 2016 SRX they gave me last time. The Lane Keeping Assist feature is one of the few things my AWD doesn’t have, and I liked it.

The much-maligned Start-Stop feature was barely noticeable; I could only tell it was engaged by the AC air flow shifting slightly when the car was stopped. Acceleration was instantaneous. I’m in a CTS for the next few days, and it’s implementation of this feature is not confidence-inspiring when making a turn into traffic; there’s a more definite lag in the responsiveness probably due to the different engine.

Nice car, but I wouldn’t be interested in it at this trim level (pretty grim) if I were in the market for one. After driving other vehicles with the Start-Stop feature, the XT5’s has the best implementation I’ve experienced. The Jeep Grand Cherokee I rented for a week recently gave me the feeling the car had stalled as it shook when transitioning at every stoplight.
