sudden deceleration on 2016 Jeep Grand Cherokee

Asked by vickicobbs Nov 05, 2018 at 02:37 PM about the 2016 Jeep Grand Cherokee

Question type: Maintenance & Repair

While driving my 2016 Jeep Grand Cherokee, occasionally it will decelerate
while I am driving.  It is enough to make the seat belts tighten.  Continued
pressure on the gas pedal and it will again regain speed.  Have taken it to
dealership twice and they cannot find a problem and test drive does not
recreate the problem since it only happens irregularly.  Has anyone else
experienced this problem?

The jeep is actually dying in motion, then recovering. You Jeep seems way too new for any of the usual causes to apply. So, here it goes: Might be a bad battery and a related problem with the alternator, like the regulator. Might be as simple as a really dirty air cleaner. Or maybe something related to fuel pressure, like a dying fuel pump or one of its controls, or the Electronic Throttle Control (ETC).

I haven't experience this, but on my wife's 2016 Jeep Cherokee, she gets this "springy" sound and a "pop" sometimes when she steps on the brake. We did the same thing where we took it into the dealership and they couldn't recreate. The only thing you can do is try to have them recreate the problem or else, they won't do anything about it.
