Exclamation What caused motor mount and tran mount failure

Inspection of front end reveals multiple mount failure. Car constantly knocks during shift from 2 to third gear and poor gas mileage I want to fix and also prevent this mount issue. Any suggestions or advice.

its a design failure.

Honda doesnt know how to make beefy mounts.
as the engine rocks back and fourth; it will wear the motor mounts out.
after market companies have alleviated this issue by making a material that is stiffer than factory mounts. however; they will still wear out over time.

unfortunately, I dont have a CL.
so, i cannot tell you which mounts are quality.

Just FYI; with stiffer mounts you'll be feeling the chassis vibrations a lot more.
if this is a concern to you; I'd stick with OEM mounts.

OP, look into XLR8 solid motor mounts or Innovative Mounts....

if you have a stick, you can also get the ingalls stiffy which is an engine torque damper...

I do agree that you will get vibrations and though the mounts....hello massage chair

uh no.....

please come back to realty... people want smooth vibration free cars and at the same time more power. high horsepower engines in a compact space = more stress on mounts... especially when one is hard on the throttle

ALL manufacturers have this problem...

putting in solid mounts = more vibration, something people don't want in their cars.

my 94 accord @ 200K+ still has it's original mounts. CL-S had then replaced at 118K. One car has twice the power of the other....

How much $$ would it be to replace with OEM motor mounts? Must the entire motor be removed to do this replacement?

no, the motor does not need to be removed.

Not all. There are many cars that make tons more power then the CLS & they don't have sold mounts or any mount problems. In the CL's case it's because of the FWD setup & the engine design & power it makes. Ever wonder why there's 3 of them? Because they couldn't be bothered to design mounts that worked for this application.

have you ever driven a high millage domestic fwd car? same problems....

Taurus and Sables eat front mounts as well... replacement below 100K is common...and they make significantly less power

^its simply a design error.

if you take a look at a greatly designed mount; you'll wonder why Honda and ford designed them like that. designed to fail. lol

a 1999 chevy malibu with 100whp has a more stout designed motor mount than my 250whp Acura TL.

typically i noticed some significant vibrations after 200K miles for most of the cars - I havent replace motor mounts in less than 130k miles. This indicates that honda might either inferior quality motor mounts or design issues.
