Broken Motor Mounts

[osidesurfer365]

So I just returned from my mechanic after a routine oil change and he shows me I have a cracked drivers side motor mount!!!! WTF... I mean seriously GM? You would think they would install a strong enough motor mount for what people use these SUV's for. My mechanic ony works with GMC and Chevy's and he said he is noticing this often.

Has anyone else experienced this problem?

Oh and cause where it is located, not the cheapest of repairs either..

Yeah I think my drivers side mount is broken too. Bad vibration at idle. Did the "foot on the brake while in drive" test to see if there was a difference left to right and the drivers side of the motor definitely raised up higher when I hit the gas

Yeah when I went to get my car he was in the driver seat and with the hood up and hit the gas and I could see the engine jerk to the right and I freaked out. He assured me I'm safe and the engine is fine. But with only 64 K miles I'm not taking a chance. Getting it fixed next week.

I have changed mine two times already. My 2008 Denali has 138k miles.

I know exactly how it is going to go....I'm going to pay my mechanic $425 to replace it. I went to my local GMC dealership today to get a price comparison and he was very honest with me and said he would charge $500.

On a different note I casually asked him if they are helping customers with cracked dash boards and he said they are splitting the insurance cost with the customer and it will cost me $500 to fix.

Update

Since I posted my frustration about the broken motor mount, I was contacted by Jennifer at GM customer care. I must say I am very pleased with the end result. The service manager at my local dealership called me today and offered to replace the broken motor mount for around $265. Originally the dealership quoted me at over $500 and my GM mechanic quoted me at $425. I am taking it in on Tuesday and will let you know how it went.

Jennifer is also working with me on my cracked dash. Update on that to follow.

Great price, the mounts cost about $70 aftermarket, so gen GM part should be more. Not a complicated job, but time consuming. You need to remove cv axle on that side (which on mine means removing shock too), remove fender splash shields, lift engine with hoist or jack and removing broken mount. If it was pass side you need to remove starter also.

If they remove cv axle the need to use a new axle nut. Also have them check boots for cracks, replace if they already have it off and there are cracks.

I replaced the driver side myself last week on my 2007 Suburban RWD.

It's not a quick and easy job. It took me about and hour and a half.

The manual says to remove the wheel well liner. I didn't.

I did everything from under the hood and from underneath.

I'm all bruised and scratched up.

I don't plan on doing the passenger side any time soon.

I understand now why they charge so much to do this.

Same thing on mine!

Jennifer,
I am having same problem with mine. It has 115K and is driven very easily by a teacher mainly just back and forth to school. I don't understand why GM choose such a wimpy motor mount for a vehicle that obviously requires a lot of torque just to get moving. Can you help?

Same Problem - broken engine mount 2007 Cadillac Escalade ESV

Hello everyone - I have the same problem. A broken left engine mount in my 2007 Cadillac Escalade ESV. I had it fixed in November at a GM Dealer in my town for $740. At the time, my vehicle had only 106,000 miles.

To me, this is a structural issue. I've seen all over the internet of this same problem (broken engine or motor mount) in the Escalade/Tahoe/Yukon/Suburban vehicles. This is a design flaw.

I called GM's Customer Service, and at first they insisted that this problem is out of warranty, thus my problem not theirs. Then when I pointed out that it's not much out of warranty, they wanted to go try and take money back from the dealer for this fix. I find that a problem too. So many vehicles with engines not secured under the hood, this should have been taken care of by recall.

Oh, and did I mention that when one engine mount goes...usually the other does too? My quote to fix both was $1,800.

I'm very disappointed in GM. I know who I won't be looking at when I'm ready for a new ride.

This isn't a problem isolated to just GM. Used to work as a service tech on Mazdas, 9 out of 10 that came in with 70k miles all had cracked or leaking mounts. Friends at other dealerships have also said its problematic on many brands.

Issue resolved

Thanks Jennifer, I went ahead and just did it myself. Thank you though, it is appreciated.

For those of you with 2WD versions it's not real easy but it's doable by any basic backyard mechanic and you don't have to remove the inner fender well. The hardest part by far was the motor mount to frame bolts. GM used Loctite Red on those bolts so will will need a lot of leverage (and a universal joint adapter) to get those 3 out. The 4 engine-side bolts are easy. When you are lowering the engine down after mounting the new mount to the block you'll need to be underneath and, using a tool (NOT your fingers), help the locator pin get into position as you lower the engine back down. One other thing, if your vehicle uses an Anchor 3211 be sure and use the original locknuts off the old mount to attach the frame mount, not the crappy standard nuts Anchor choose for some stupid reason.

Gina,
It is not true that both mounts need to be replaced on small block GM motors if the left one breaks. Unlike Mazdas (which I also have) with their traverse mounted engines, the the left side small block GM motor mount takes 90+% of the elongation or tearing torque while the right side gets only compression torque which is not damaging (unless you drive in reverse all the time then it switches). Since I haven't heard of this issue in any of the non-truck vehicles it appears that these mounts are either being subjected to either too much torque (moving a big, heavy vehicle is ******* mounts) or too much radiant heat, or a combination of the two which is what I suspect is the real cause. Was it a case of a supplier material issue not meeting spec requirements or was it a design flaw, who knows? One thing is for sure, without knowing for sure that the elastomeric material in the replacement GM mounts has been redesigned I would not go back with another GM mount unless the dealer is willing to give you a lifetime warranty. My replacement Anchor mount does have a lifetime warranty, as does my labor; although, I am hoping to not have to exercise that clause.
