Engine hours

[DonZ1lla]

Good evening everyone. I just purchased an 06 Yukon Denali with 90,000 miles. It is in like new condition, garaged from FLA. I did the usual mods, Esky roof rack, new lights etc. Upgraded the audio with Apple car play, back up camera etc. I paid 17K. Thank God I found it and avoided paying big money for a newer SUV. But I’ve discovered something odd. The DIC only says 717 engine hours. That makes no sense as it would mean the previous owner drove an average of 125mph. Any ideas? Thanks

May be a replacement cluster that only had mileage transferred. When I replaced mine, I had all the historical data loaded (mileage, hours,….).

I'll need to see what mine is at... My 2002 has 89K miles. I would guess north of 3500 hrs.

2005 GMC Yukon Denali with 81K miles and just over 500 engine hours...no indication or signs the cluster was ever changed...

My '05 2500 Silverado Duramax had the cluster replaced before I bought it. At 142k miles when I purchased I knew the hours weren't right. Unless the vehicle was used for a construction company, police, or from a fleet I wouldn't worry too much about it.

Just checked mine. 89,795 miles 4323 engine hours. Average speed 20mph. Mileage 100% confirmed by Carfax. 1 owner vehicle almost exclusively driven in City with idling so I'm not surprised.

Our 2018 Tahoe was a highway queen. Had 81K miles in 2-3 years!! Even then I think we had over 2300 engine hours when we sold it (we had accumulated a lot more city driving towards the end).

I would run a Carfax on your vehicles to double check odometer and/or history. DM me and I can hook you up with an economic Carfax.

Just checked our 2003 Z71…
240466 miles / 6803.6 hours
35.34 mph average
Owned since new.

my CarFax also backed up the original miles on my Denali...

Ok that's good and all that matters really...

However

500 hours engine ON time to achieve 81,000 miles is just not possible. That would mean the vehicle was driven at an average 162 mph.

A cluster swap would explain. The cluster comes of rather easily on these vehicles. You wouldn't be able to see cosmetic signs of cluster being swapped. (No headlight switch, wiper or radio knobs, or transmission shift indicator to contend with like the old school ones)..

well if they changed the cluster, I wish they brightened the odometer and the DIC...

thanks,

Bill

Got a used 2021 Yukon from Hertz a year ago - it had 50Kmiles and showed ~2100hrs. 50,000miles / 2100hrs = 23.8mph. Maybe this makes sense?

Our 05 Denali had a loose cable that did a momentary dead short out on the road. Engine hours went to zero when that happened. I never worried about the inaccurate engine hours, as they has also been zeroed at a cluster repair some time prior to our purchase at about 3 years and 36,000 miles.

50,000miles / 2100hrs = 23.8MpH. Maybe this makes sense?

Why wouldn't it make sense?
Most rentals accrue most of their mileage in stop'n'go. Many NYC cabdrivers get even worse average MpH than that.

Our Escalade was bought at 72K ...and had 4000 engine hours. 1 Owner mileage confirmed by service and carfax. Turned out it was a Mom w/ 2 kids and literally sat on 2 different school lines a day (which is 4 times a day)and athletic practices. Did alot of idling. Fantastic well cared for truck, not one issue.

 

[DonZ1lla]

So I found out that there is a bulletin on this issue . Engine hours randomly reset on these vehicles.

 

[SilverSport]

could you share the bulletin/detail for some of us?...I'd like to know but have been unable to find it

Thanks,

Bill
