Just the other day we noticed that the lifetime MPG shown in both the OnStar RemoteLink and myChevrolet apps is displaying 37 MPG, whereas in the vehicle itself it's correctly showing over 107 MPG.

Has anyone else noticed such a discrepancy?

Mine shows 136 on my Onstar App and 143 in the car.

My assumption was that the ECM was reset at some time and caused the discrepancy.

My situation is similar to Rooste's but I'm pretty sure that this isn't what the lpickup is talking about -- Short answer to Original Poster is "Yes, many people have reported this glitch, which isn't affecting everybody." (I suspect that someone screwed up something in the databases behind all this but affects so few people in the total OnStar universe that it's not a high priority to fix, much less to make an announcement about.

Mine dropped to under 10 was 147 day before yesterday. Real issue is the program does not count miles driven when ERDTT as gas miles but electric miles on my 17. It shows it as gas miles for the current discharge cycle but not for the lifetime. It shows 1885 miles total and 1759 electric. I know some days here in Michigan I drove 1/3 to 1/2 the time in ERDTT, all those miles were counted as electric miles.
