Car Talk

DEAR CAR TALK:
Our 2014 Jeep Cherokee shuts off
when making right hand, uphill turns.
First and foremost, this is dangerous.
The dealer says that when oil
doesn’t get to the top half of the
engine, the engine will stall. They said
we weren’t changing our oil on time.
They did an oil consumption test and
said we were losing four quarts every
5,000 miles.
I submitted a complaint to Safercar.
gov and the NHTSA about this problem. While I was online, I found that
there are other Jeep owners with the
same problem.
What’s your take on this? — RICK
DEAR RICK:
My take is that I’m glad I’m not the
owner of your 2014 Jeep Cherokee. It’s
not only unsafe, it’s also going to be
difficult to diagnose. Not to mention
difficult to sell.
Jeep has had a raft of complaints
about stalling Cherokees. And as far
as we can tell, they haven’t figured it
out yet.
A bunch of people report that
Jeep is blaming low oil level.
But you’d have to be very
low on oil to cause the
engine to stop running.
I’d say you’d need to be a
minimum of two quarts
down.
According to Jeep’s
own consumption test,
you’re losing a quart every
1,250 miles. That’s not a
ton of oil loss. As long
as you check it and

add a half-quart every 600 miles or so,
you’ll never get anywhere near low
enough to cause your engine to stall.
In fact, if you’ve been driving the car
with your crankcase full and it’s still
stalling, that tells me the oil level has
nothing to do with it. So, we’re not
buying the oil level explanation.
The 9-speed transmission in this car
was also problematic. That’s another
possible culprit, along with the transmission wiring harness.
You can check all of your wiring
harnesses by wiggling them while
the engine is running. If you can get
the engine to stall, you’ve found the
source of what is an electrical problem.
The other major problem this vehicle has is with something called the
Totally Integrated Power Module, or
TIPM. It’s kind of the electronic brain in
this car. Like Hal from “2001: A Space
Odyssey.” That could also be the cause
of the stalling.
If your dealer is willing to work with
you, ask him to install a new TIPM on
a trial basis and see if that solves
your problem. If it does, you
can take out the requisite home equity loan
and buy the thing. If
not, you can give it
back, and go back to
wiggling wiring harnesses and crossing
your fingers on right
turns. Especially when
they lead across railroad
tracks.
We wish you luck,
Rick.
