    On the other hand, just how much (engineering or otherwise) foresight is required to design an A/C compressor that can have its clutch serviced...or at least replaced?

    More than is typically applied.

    Like...what did they save in length...maybe 1.5 mm?

    What they saved is production cost.

    No doubt instruction is handed down from the top, but management should be concerned with measures they sign off on which can taint their brand's reputation when the consumer is considering their next replacement vehicle.

    I'm in an odd position in that I could buy a GLK250 (mainly for the engine being a not just a diesel, but an unusually powerful and economical one) and its 4x4 and towing ability and the fact that no other more affordable brand is offering that combo. But I am drawn to a lowly little name plate, Kia, and even their entry level model, even tho it is not a diesel and worse, not 2WD, and will be noticeably noisier to ride in on the highway even if the ride and handling are not that bad for a cheap car. Why? Well...in some respects it is the simplicity of the car. I can still get rear drum brakes. And astonishingly I can replace a bulb if need be with my already good supply of 1157 bulbs. In a 2013 car! This might be a stand alone anomaly, I don't know but plan to check into things like this further. If I were to extrapolate on just that one example of Kia not abandoning things like 1157 bulbs just for the sake of change, which always translates to greater consumer costs down the road, then a person could ponder how great it would be to have maybe one of the last relatively simple cars to work on compared to what is left out there.

    I'm not oblivious to appreciating engineering styles, feats and/or recognizing shortcuts, but I feel compelled to give credit where it's due, and to some personalities out there..even including some of the more idiosyncratic ones (me at times) a manufacture's decision to retain the use of old but proven competent parts like the use of 1157 bulbs which worked just fine for decades, and the prospect that maybe there are many other components of this entry level car that may also fall under the simplicity class of an 1157 bulb, start to take on a potential worth, greater than the sum of their parts. Factor in other important aspects like seat comfort and quality feeling switch gear (the signal lever spring resistance before slipping past the point of lane-change to locked switch position had a more tactile feel and resistance than a near 40k $ Subaru, and you have to recognize the value of a little car priced at 17k vs a near 50k MB. And remember, this consumer can buy either with cash.

    So, the odds of me ending up in that MB with its complexity and change for the sake of change, and quite possibly also donning a non-serviceable A/C compressor, are probably pretty slim...but hey..now if I discover it has a few 1157 bulbs on board, well...ya just never know...but I ain't holdin' my breath on that one..

    Well of course...that is a given..
    The arrogance and greed irritates me. It's already a frig $35k car!...that really has no more to offer than a 23-25k car and only that much cuz of the supercharger urge it has. And the name...ugh..

    When you spend this much of a premium for a car of this category, you darn well shouldn't be expected to endure insult to injury from this type of cost cutting to the point that you have to replace the A/C compressor as an entire unit.

    I would tend to agree...a BMW product is in my experience a car that starts to open its mouth real wide at 80K---100K, and you'd better punch out as soon as the clock turns to 99,000.

    Similar issue with the sunroof on the MINI---if the rear glass panel breaks, (the stationary piece) can you replace just the glass? No, you replace the entire 'cassette'--that means the entire frame + pre-installed rear glass, and you remove the headliner, too, which you CAN'T very easily do without removing the seats! Welcome to a $2,800 repair for a piece of broken glass!

    As these punishing repair costs continue to add up on new cars (and it'll only get worse), I can see the day when cars will be recycled by the factory at a set mileage---then perhaps "refurbished" like they do with computers on Amazon, and re-sold again at a discount.

    Progress is made one step at a time.

    I'm waiting for the OK to repost something from a GM technician from Florida. It will shed some more light on this topic.

    FWIW, I had a 2005 Chevy Aveo with moonroof. After 2+ years and about 30K miles, the mechanism began to start making a binding noise, and the only option was total cassette replacement. No provisions for lubrication (lifetime fill, once again).

    A $1200 job, but fortunately for me, it was covered under warranty. The vehicle's cost was right at $15 K new.

    So, in three months I can hang up a shingle and start fixing Malibus? Cool.

    you can hang your shingle now. All you need is a work space and a business license.

    Please correct me if I'm wrong here, but it is my understanding that a high school kid with no training on cars whatsoever, could open up a Brake Repair shop in just about any state of the union.

    I need the validation. Certified GM tech has a nice ring to it. :shades:

    So along with Bozo' s Automotive Repair, we could have Jipster' s Brake Service and Shifty' s Mini A/C Repair? With professional sounding names like those, we'd make a fortune! :sick:
  • steverstever YooperlandPosts: 39,936
    We could hire on with Fairly Reliable Bob's used cars in Boise.

    That dealer actually enjoys a good reputation - plus you gotta love truth in advertising.

    Nah, ya gotta have the word "certified" in there someplace.

    So that would become Jipster' s Certified Brake Service and Shifty' s Certified Mini A/C Repair.

    I'll take door #2 instead of Mini AC repair...crawling through shards of broken glass 8 hours a day would be nice :P

    No, not exactly. You would however get to be a dealership technician and be expected to be productive on flat rate and meet or beat the following labor times.....

    From James.

    For example, let's look at a common G.M. car, the 2012 and
    2013 Malibu. That's basically the same car with few changes.
    There is no reason for the repair times to be different.

    2012 Malibu - replace ECM and program - .9 and .3 diagnostic
    time.

    2013 Malibu - replace ECM and program - .4 and .3 Diagnostic
    time

    2012 Malibu - replace electric steering column - 1.3 and .3
    diag and .3 if adj. pedals

    2013 Malibu - replace electric steering column - 1.3 no diag
    or pedal allowance

    2012 Malibu - replace and program SDM - 1.2 and .3 diag time

    2013 Malibu - replace and program SDM - .9 and .3 diag time

    2012 Malibu - reprogram ECM, SDM, HVAC or EBCM - .4 - no
    diagnostic allowance

    2013 Malibu - reprogram ECM, SDM, HVAC or EBCM - .3 - no
    diagnostic allowance

    and Shifty' s Mini A/C Repair

    Lol, I'm not too sure about that one, jipster...just cuz Bozo seems to be getting away with it, doesn't mean other consumers are gonna trust a shop named "Shifty". haha..Of course they never knew that Shifty's full name (before the Edmund's mod name-chop last month) was in context with enjoying shifting a stick tranny..

    Not even sure if having "Certified" in there would help much...maybe a hair.. lol
  • steverstever YooperlandPosts: 39,936
    "Programming" and flashing chips isn't geek Greek to me so I'd probably do okay with that (so long as that was my assignment - forget the diagnosing part).

    I'd be sure to break any clips on the trim around the steering column first thing. :shades:

    I'd probably destroy quite a few customers' cars but you know, in time I'd get better. In the meantime, I'll use the standard excuses:

    "oh, they all do that"

    "it's a factory defect"

    "could not duplicate"

    "oh, you wanted brakes on BOTH front wheels..."

    "no codes detected"

    "it's your brother-in-law's fault"

    well, he might make a killing with the British car crowd (they always need mechanics!) if he called it "Sir Nigel's auto service" instead.

    2013 Acura RDX (wife's), 2007 Volvo S40 (when daughter lets me see it), 2000 Acura TL (formerly son's, now mine again), and new Jetta SE (son's first new car on his own dime!)

    So no comment on the labor times listed, for the same jobs? Flat rate is supposed to be piece work that pays the tech a fair amount for a given job and through experience and attention to detail the tech should get rewarded by improving his/her efficiency. The times listed for the 2012 models aren't routinely achievable, the 2013's are the very same jobs and are now about 50% of what a good tech can expect to achieve without breaking stuff.

    GM is looking for more techs through that school, they know they have a technician retention issue and yet are turning right around and ensuring the next group can't possibly thrive, unless they sell un-needed services that is. How about the media start concentrating on the real problem instead of only focusing attention on one of the final outcomes?

    The times listed are simply impossible to meet and should be at least double across the board. There are technical writers looking for something to do, lets get them help to do legitimate time studies and prove how long it really takes to do some of this work. What you'll find is they won't even have the failed PCM diagnosed before the time to replace and program it expires.

    BTW GM isn't alone with warranty times like these. I should look up the warranty times to diagnose and repair your Mini, its probably half of what you said that it took.
