    flash update

    You should not have lost the flash update. Much like with BIOS on a motherboard, 'flashing' a PCM is a permanent change until you complete another flash to revert back to a previous, or update to a newer version of the software.

    High Piched Whine

    Almost sounds like the fuel pump. In other vehicles of mine, they've always made a slight whining noise. Haven't noticed it on the RAM.

    rust on rear seats?

    I've had rust on various seat brackets and parts inside the car in just about every car I've ever owned. Moisture gets into your car, and becomes a great environment for it to rust things. I'll have to check my RAM when I get back from overseas.

    2020 Rams come with 100,000 mile warranty

    Be interesting to see if this truly is for all RAMs. I could understand it for the diesels, given the issues the eco diesel had previously along with the VW-like scandal. Also, the Cummins equipped 2500/3500 have a 5/100 warranty as well, which might show consistency for this being a diesel thing.

    Surge when letting off brakes

    I'm afraid you are right. I knew there would be issues on a first year model, but didn't think it would be the technology that's almost as old as time now, like a drive shaft. :ROFLMAO: But, seeing how FCA took care of me while I had my Grand Cherokee, and with the few issues we've had with...

    Surge when letting off brakes

    I honestly do not know what to make of it. It's certainly back, but for the first few days / hundreds of miles, it was back to perfectly smooth and without a bump. It started back gradually, to the point of me thinking it was simply my imagination after dealing with it for so long, but that's...

    Auto AWD vs 4WD high

    Mine also feels a bit tight in 4WD Auto on turns, usually just with some clutch noise as I'd describe it. The way I see it, when you are turning, all four wheels are turning at different speeds (inner vs outer wheels, front and back) - this makes the transfer case sense slippage, and hence the...

    0-60 Time with the 5.7L and 3.92 axle

    If anything, the speedometer and related components are probably slower than actual rate of acceleration. My Grand Cherokee had the same engine but with 360hp and 390ft/lbs compared to our 395/410, and was able to do 6 seconds with 3.09’s and same transmission. Vehicles weigh similarly as well...

    0-60 Time with the 5.7L and 3.92 axle

    I had it in 4auto, anything over half throttle off the line will just spin for me in 2wd. :LOL:

    MOPAR bug deflector

    Looks right to me. Agreed that it’s an odd placement / design.

    Went in for second oil change with 10K miles. Getting a new transmission.

    Hey friend, the dealer wouldn’t give me the case number unfortunately. The new driveshaft made things great for the first two days, but it’s back to doing the bump again - but it’s less severe than before. I’m on the road right now but it you search my posts, I shared the dealership work invoice...

    What Fuel is everyone using?

    I’ve used only 89 in both my 5.7’s over the years. On my trip down to SC from VA, I got 20.5 mpg - with a bike rack loaded up, and cargo in the bed. The tonneau cover probably helped. I have 3.92 gears as well, no etorque. My commute mileage is usually around 16, with heavy stop and go.

    Surge when letting off brakes

    Just an update: it has been exactly one week since my truck got a new driveshaft under warranty. That seemed to make the bump/surge go away. It has now returned, though not nearly as harsh as before. I took a 400 mile trip to South Carolina and have been driving around down here all week, maybe...

    Surge when letting off brakes

    I can get it to very lightly do so under the right conditions. If I slow down or stop very very slowly, I can get it to happen - but it’s very soft and nowhere like the violent jolt I had before. Under normal driving and stopping it will not do it at all. I haven’t heard the start up clunk since...

    Surge when letting off brakes

    Well, the new drive shaft fixed it for me. No more bump after stopping / letting off the brakes, or when accelerating. I will update in the morning after my cold start before work, as to whether this also fixed the start up clunk that someone else asked about. I've redacted some info, but here...

    0-60 Time with the 5.7L and 3.92 axle

    Old habits die hard! Manual says it's good after 300 miles, so yeah - hardly a break in by old timey standards. :LOL:

    Choosing Best Tonneau Cover

    Just picked up my Undercover ArmorFlex last night from a local shop. I didn't want the hassle of having to schedule a freight delivery during the workday if I ordered it online, along with having to inspect everything and then sign for it. The shop got it for me in one business day, and they...

    Surge when letting off brakes

    I will absolutely do so, friend. I've received a tremendous amount of help on this forum, and will gladly contribute as much as I can in return.

    Surge when letting off brakes

    Check out this thread: https://5thgenrams.com/community/threads/rear-end-issue.1684/page-2#post-154152 I have this exact same issue. Upon coming to a stop, a bump feeling when letting off the brakes. The times when it does not happen, I get the same bump when accelerating from a stop instead...

    Keyless Entry on BigHorn Models

    I had a Big Horn as a loaner while my Laramie was at the dealer a couple weeks back, and this was the #1 thing that bothered me about it.
