Rear mag shock probs

While the system could theoretically figure out if a shock is bad, since it can see how quickly the suspension is moving in response to how much dampening it's applying, I don't think it does. Just codes if the magnetic coils are disconnected or if the sensors aren't sensing correctly.

If your shocks are bad, they should be leaking. Are they? A bang going over bumps could be other things.

At this time in theses cars lifespans you can probably presume they are bad. My fronts weren't bad but backs were. I changed them all. If you feel bumping or the car pulling one way or the other under acceleration you should replace them.

The best replacement is the OEM magride and they are the cheapest at rock auto at 320 a piece.

Struts and shocks aren't going to throw codes. The degrade slowly. So slow that you don't really notice until they are really bad. When you get new ones it feels like a new car

I replaced all four shocks recently for OEM mag and was impressed with the difference. Like others said mine wear leaking in the front and car was bouncing all over the place. The rears weren’t leaking but would make this weird water bubbling sound when I would make turns. I got all my shocks from rock auto should be your best bet.

Typical failure presentation for 'normal' shocks would be bouncing and or leaking and possibly rattles and squeaks. Specific to these MagRides, add in the code throwing for sensor issues, leaking is common but jolting or harshness is not often mentioned. I think you should take a good look at the rest of the components before buying the shocks. No doubt, given their age, they likely ARE due for refreshment, but the jolting may be something else.

I had the same symptoms in my '12 wagon last spring at about 75k miles - a jolt from the rear end when hitting bumps at any speed, even expansion joints on the freeway gave it a jolt. Rears had basically locked up, but no significant leaking or visible signs they were gone. Fronts were dry and working fine. Replaced the rears with OEM and ride was like new again.

Not sure if you were responding to me but yes my front left control arms and bushing were shot. So I did all four shocks left control arms with bushing and aligned the car with brand new pilot sport 4s. Car rides better than ever.

Off topic but picked up the car today from getting rotors and brake pads done. Did the DBA 5000 series up front 4000 series in the rear with Hawk 5.0 pads. Car stops on a dime.
