Piston Slap: Cancelling Chrysler's Noise Cancellation?

Craig writes:

Hey Sanjeev, (*facepalm* –SM)

I have a 2015 Jeep Grand Cherokee SRT, and I’m bit of a music buff. One of the first things I dispensed with was the factory Harman Kardon speakers. I replaced the sub with a JL stealth box. Now I have a pretty big problem with the factory stereo and its the automatic noise cancellation.

When the transmission is in normal D mode and or eco mode is on, it uses the factory stereo to cancel out the drone of the engine. Unfortunately, the noise cancellation is calibrated for the weaksauce factory sub. Now it sounds like one of those bass CDs from the ’90s as I hold speed or decelerate. I’ve asked the dealer how to get rid of this thing, to which they said “you can’t.”

I’m not so convinced.

Any ideas?

Redapple2 Love the wheels
Redapple2 Good luck to them. They used to make great cars. 510. 240Z, Sentra SE-R. Maxima. Frontier.
Joe65688619 Under Ghosn they went through the same short-term bottom-line thinking that GM did in the 80s/90s, and they have not recovered say, to their heyday in the 50s and 60s in terms of market share and innovation. Poor design decisions (a CVT in their front-wheel drive "4-Door Sports Car", model overlap in a poorly performing segment (they never needed the Altima AND the Maxima...what they needed was one vehicle with different drivetrain, including hybrid, to compete with the Accord/Camry, and decontenting their vehicles: My 2012 QX56 (I know, not a Nissan, but the same holds for the Armada) had power rear windows in the cargo area that could vent, a glass hatch on the back door that could be opened separate from the whole liftgate (in such a tall vehicle, kinda essential if you have it in a garage and want to load the trunk without having to open the garage door to make room for the lift gate), a nice driver's side folding armrest, and a few other quality-of-life details absent from my 2018 QX80. In a competitive market this attention to detai is can be the differentiator that sell cars. Now they are caught in the middle of the market, competing more with Hyundai and Kia and selling discounted vehicles near the same price points, but losing money on them. They invested also invested a lot in niche platforms. The Leaf was one of the first full EVs, but never really evolved. They misjudged the market - luxury EVs are selling, small budget models not so much. Variable compression engines offering little in terms of real-world power or tech, let a lot of complexity that is leading to higher failure rates. Aside from the Z and GT-R (low volume models), not much forced induction (whether your a fan or not, look at what Honda did with the CR-V and Acura RDX - same chassis, slap a turbo on it, make it nicer inside, and now you can sell it as a semi-premium brand with higher markup). That said, I do believe they retain the technical and engineering capability to do far better. About time management realized they need to make smarter investments and understand their markets better.
Kwik_Shift_Pro4X Off-road fluff on vehicles that should not be off road needs to die.
