Hi all..


I bought a new 2001 GMC Jimmy 4WD in Nov 2000. Today, it still only
has 23000 miles on it. This vehicle has had continuing electyrical
problems from new as follows:

1. Going over even a small bump (aka even a slight "crack in the
road" as SLOW speed (1 mph) may cause ALL of the dash warning lamps to
come on....for about 10 seconds ...exactly in the manner as they
appear when the vehicle is started. This does NOT cause the engine to
stall.

It would seem (to me) to indicate an intermittant connection feeding
power to the computer...which likely controls the sequence of lights
at startup. A very short power interruption...long enoughjt to
trigger the diag-sequcne, not long enough for the engine to stops.

IDEAS?


2. Problem 2 (may or not be related)....On June 5l of this year, one
morning the vehicle started, but as soon as I let got of the key, a
few seconds later it stalled. This repeated 10-12 times. Finally, I
managed to keep it going, then it seemed ok. Made an appointment for
service for the next day, but after driving about 10 miles (3 stops) I
came to a traffic light and the engine at about 10 mph speed) stopped.
At that moment, I had ZERO electrical power, so I could not even use
the e. flashers, or even move the shifte (A/T) to remove my KEY!

No chance...the dealer (4 miles away) refused to tow the car (!!!!!)
or even call GM road-side assistance. Finally, the police came along
and called a tow which cost $100- and should have been freee via GM!
The dealer is still fighting about paying for this!

In any case, the battery was dead...they replaced the alternator (the
second replacement in 23K miles!).

The car drove ok for 400 miles (2 weeks). On June 24, the car started
normally in the AM. I drove about 8 miles, with about 4 stops. ON
trying to start (5th start of the day), the car started, but as soon
as I released the key it quickly stumbled and died. This repeated 5
more times, including once when while the negine was running, all
warning lamps came (as per usual start sequence).

Finally...I gave up and had the car towed back to the dealer again.
Of coursem, this took a few hours and by then the vehicle started
ok!!!!!!!!


ANY IDEAS.............


Thanks for help, comments etc.

Ignition switch out of adjustment or going bad.

---Thanks...That was my gues too....It was replaced about 18 months

I'll post the results here...since if it helps I'd like all to know.

Again...thanks for your feedback

This sounds suspiciously like a power problem (ok, maybe we all
firgured that out). Sounds like there's a bad ground somewhere in the
system. Fortunately for you, the problem is documented in warranty,
so if it happens out of warranty you have a better chance of getting
GM to fix it. Tell the dealer they need to put their best electrical
tech on the case and you will NOT take the vehicle back till they can
provide an EXACT cause of the problem, and can honestly tell you they
fixed it this time....
