Canadian Hummer Club Forums

I'm the proud owner of a Yellow 2007 Hummer H3 with 140 kilometers. I have invested in chrome mags and all the trimmings you would expect from a proud Hummer owner. Yesterday, while driving home I lost power on the highway and pulled over immediately to find fluid leaking - looked like the radiator was leaking. After being towed to the ONLY Hummer dealer in Ottawa Ontario I'm told I need a new engine? How can a leak in a rad hose burn out my engine after 6 years? The used Hummer engine replacement has 123K with a one year warranty and costs $2,000.00 - to install it another $2,000.00 = $4,000.00 +! I'm pretty upset right now because I maintained my Hummer and thought I did a good job as a owner to ensure it was in good condition. I didn't drive it for miles with no coolant - I pulled over right away.
 
The dealer told me it could have been the timing chain but not sure. There was no compression in 3 valves so it's better to replace the engine versus trying to fix but not sure what is damaged.
 
I spent time on the internet and it appears the Hummer has problems with the radiator leaking so, please check your rad's for leaks. I also found Hummer H3 engines for $1,400.00 NOT $2,000.00 but what can I do when there is only one Hummer dealer in Ottawa. Yes, I'm getting royally screwed but I have no more warranty.
 
When I get my Hummer back I'm afraid I'll have to sell it because I cannot afford to pay for the engine replacement. I wish you all well with your Hummers and hope you never experience what I'm going through now.

Yuppers , bad Design, plastic with internal trans cooler. It most likely cracked on top and the foam insulator/ Dampener there hid it . Very sorry to hear about your rig and stress you must be going through.That suck's bro. Other weak area's on the rig are head , front cross member bushing,steering rack, transmission ( which some will argue they are not), blower motor relay , T-CASE PLASTIC FORK . A few other odd ball electrical things have been reported . 

If you are out of warranty now would be a good time to look around for a local mechanic ask some of your friends who they deal with. If you can find a motor else where cheaper and with a warranty of some sort that is the way to go. 
Now I don't know the Ottawa area for mechanics but around my area most would do a swap for about a grand don't be scared to throw that word cash around to the mechanics they like cash that is why it is a good idea to ask some friends who they go see so you have a referral.
Hope this helps and helps you in keeping your hummer it can save you some money.
Cheers

Thanks for your comments and suggestions.


I got my Hummer back yesterday. $4,500.00 later it seems to be running ok except this morning cold start sounds strange??? Not sure but after it warms up it sounds better. I think I'll take it back to the dealer on Monday.

Any thoughts on this sound ?

Most likely a bad pulley or not tight enough . Start it -video it- with your cell or cam and upload it . Remember they are GM mechanics and are masters of changing parts not really fixing anything .What did they give you warranty wise ?? 1 year parts and labor ?

I did get a 1 year warranty parts and labor on the replacement engine. I'm taking it back on Wednesday because of this strange sound and have recorded the sound on my iPhone for them to listen to.
 
I now have a "Fuel Cap" light come on every once and while yet I have replaced the fuel cap last year. Is this a problem with emissions control?  
 
Thanks for the responses - greatly appreciated in hour of depression and anger.
