LW300 BCM failures

Discussion in 'Saturn L-series' started by Dana Rohleder, Nov 1, 2005.

  1. Last week, on a 600 mile trip, I began to notice that every 10 minutes or
    so, the tach would drop to 0, and the SES light & service (wrench) light
    would come on simultaneously for about 1-2 seconds, and then return to
    normal. Over the entire trip, this happened about 20 times. The car would
    show no signs of loss of power, and no lights illuminated at any other time.
    The remainder of the week, it drove normally, and no lights came on during
    short drives.

    I took it into the Saturn dealership yesterday and just as I pulled in the
    service entrance, my ABS light came on and the service wrench flashed. They
    diagnosed a failed Body Control Module (BCM) and promptly removed $423 from
    my pocket ($279 Parts, $144 Labor).

    The vehicle has 63k miles on it, and the warranty is out. Can I get a show
    of hands of others that have had BCM failures? Over the years, it seems this
    was a fairly common problem in the group, and I'm trying to figure out if I
    can get Saturn to take responsibility for the part if they are very prone to

    I bought my '01 lw300 with 40K on it through saturn.
    About a week after I got the car, noticed that the ABS light did not come on
    at key on. They poo-poo'ed it and I held my ground (what the heck, I only
    got a 90 day warranty). Tech did find something questionable, showed it to
    the sales manager who grumbled and walked away (service cost came out of his
    commission). They did put in a new BCM and programmed it - all under
    warranty (whew).

    Now, if I can only fix the darn brake light that keeps going out (supposed
    to be a recall that never happened). Also, the rear dome light is
    intermittant. Looks like a harness problem.

  3. The recall for the taillight is is Recall# 05V245000. I just had it done
    last week.

    That is good to hear, Thanks.
    Did you get a recall notice or did you take the first move? Any idea *what*
    the fix involves?

    At this point, I have the NY state inspection due next month, will likely
    have them take care of it all when I take it in.

  5. I just took it in for an oil change and they told me they were going to do
    it. I didn't receive a letter like I did for the seat belt recall. They said
    they changed some brackets and circuit boards(?). I know they have had
    voltage regulation problems causing the socket area to melt if your brake
    lights are on too long, or something like that. Most of my driving up here
    in the Adirondacks is highway, so I don't use the brakes much.

    I believe your dome light issues could be due to the BCM, as it controls
    virtually all interior lights & switches. Rule out the wiring first, but if
    something doesn't make sense, it is likely rooted in the BCM. My suspicion
    is that the voltage regulation problems these cars have with pulsing
    headlights and instrument lights, hot turn signal switches, melting tail
    lights, fuel gauge problems, etc, etc, is either a result of faulty BCM's
    causing the voltage problems, or the various voltage problems are ruining
    the BCM's. I am going to hold onto my receipt for the BCM bill and pursue
    the issue with Saturn.

    On many cars a bad ground or bad battery can cause all kinds of issues.

    I have a 2001 LW300 with ~74300 miles. Back in March '05 I had a
    crankshaft position sensor fail and had it replaced. Then in June '05
    there were "issues" and I was told that the system was found out of
    calibration (which I had to pay ~$100 to recalibrate) and they did and
    engine oil flush. Then in Nov '05 (car is still currently at dealer
    being "repaired") I had the following all happen at once: BCM (body
    control module) failed, Mass air flow sensor failed, oil cooler leaking
    and a failed battery (which I bought from them Aug '04). The repairs
    for this last trip were estimated at ~$1600 (They were only going to
    replace the battery under warranty). When I expressed concern at so
    many items failing all at once they lowered the price of the oil cooler
    leak repair to $500 (was $960). Then I called Saturn and they "worked
    with the dealer" and lowered the total cost of repair to $992. However,
    I still feel that there is something fundamentally wrong with the car
    and that they are only repairing the symtpoms of a bigger problem.
    Otherwise, could someone explain to me how two sensors and a computer
    module fail on one car (that is 5 years old and at ~74300 miles) in
    less than a year? It's a stationwagon for crying out loud... not like I
    drag race it or take it off road! Ever since I've had the car I have
    numerous "SES lights" and service lights, etc. popping on every so
    often, mostly to be told that "It was just a misfire... we've cleared
    the codes and reset the system".... Bull. I think Saturn needs to
    address the BCM issues at the very least.
