I agree with @Transient here because I did the same thing today with my High Country. Washed it in a heated bay with high pressure washer. We have had a blizzard past 2 days and I wanted to get all the grime, salt, and chemical $hit off my truck.  Took me an hour and half to wash and dry it.  Truck took a ton of water in on the front end because it was covered with “grime” from driving on interstate. Truck started up just fine. There has to be something else going on with this issue. Plus, with all those videos I posted earlier in the thread.  These Trailboss’s have been tortured by GM themselves along with all kinds of car magazine publishers. I can’t see how OPs truck did what it did.  There is an underlying problem. Hopefully it get taken care of. 

Yeah I can’t understand how this happened either. I got my insurance involved but will still keep trying to get a hold of GM. Sounds crazy

I just took the time time to watch both of the Trail Boss videos in the earlier post and I may have found the problem.    The OP probably didn't have his DRL's set to strobe !  I didn't see

Gus stopped posting once he realized nobody here believed him and we knew his story was garbage.     Based upon you mentioning 5" of water and 30MPH driving speed, I have a feeling this will

I know this doesn't help your current situation but If you haven't considered one, get yourself a good dashcam. When I'm in my truck the cam records video and audio. It quite possibly could have caugh

Boy am I glad I got the 6.2L haha! Hopefully this “bigger better” engine will be able to handle a few puddles. 

It isn’t better. I hydro locked my 2020 6.2L Trail Boss last week. I’m in disbelief that it hydrolocked in a 5-7 inch puddle. Unbelievable. I may have to file an insurance claim. I don’t even want this truck anymore. I’ve only had it for 3 months.

Yeah, he has a whole thread on it. It sounds questionable though.

I google searched it and found about 4 people claiming to have hydro locked their Trailboss. Not a huge number but still interesting and a little concerning. Might have to replace the stock air box and roll with the performance CAI. Interestingly I can’t find it on the official GM accessory page anymore.....

So, after today I do have to question this situation, even though I posted a similar story earlier about how I can see it happening because it happened to me. I took my car to the wash today. It's one of those do it yourself places with the brush and high pressure sprayer. I decided to clean under the hood this time since it was dirty from 9,000 miles of driving. I did the engine degreaser, high pressure spray, low pressure spot free rinse, etc. I have the GM Performance intake. You betcha a ton of water went down that tube before the radiator. After I finished washing my truck I got into it and it fired right up. I drove it out of the bay with no difficulty at all. I drove her home, which included surface and interstate driving, and going up and down hills. When I got home I backed her into the driveway. Since then I took my son to the batting cages, took him to dinner, went home, realized my wife didn't feed our 2 kids and it was already 8pm so I got back into the truck, went and got food, and drove it back home. Several engine cycles, and no issues with water in the engine. Based on post #1, either the water was 4 feet high, or something else happened to the engine. I wonder if we're looking at a broken valve spring that resulted in engine failure? What's the build date on the truck? Truck was built in March, so I don't think that's the issue. Does it rain hard enough to get 4 feet of water in a parking lot in Los Angeles? I doubt it. It's not Norfolk, VA.

I agree with most of what your saying, there was literally 3”-4” max of water at the time this happened. I took it to a second dealer for a “2nd opinion” and they agree with me that this seems to be an issue with the vehicle. Obviously no water damage in the sense that I was in 4’ of or anything close to that. Actually just got a follow up call from GM yesterday that they will revisit this case and is now working with the new dealer I have the truck at. I have filed a claim through the BBB so I’m sure that lit the fire too. I also ha e a claim through my insurance but because it’s costing 13k for the repair they have to get “approval” from a senior advisor so there is some delay. Either way I have had now 3 brand new Silverado’s in the past 11 years and never had an issue with anyone of them until now. I always had the 2wd trucks and the first “off-road” truck does this I’m 3” of water? Seems crazy!

So GM finally got back to me yesterday after a month of nothing, not even a peep! They are going to “re-open” my case and see if they can get it right this time. I filed a claim through the BBB and that kind of lot a fire I believe but who knows. The point is I have filed a claim through my insurance and am waiting on approval because the cost is 13k to get a new engine. My truck had 9k miles and I had it only 9 months when this happened. What state do U live in? I’m in California (unfortunately)...

I just recently replaced my motor to my 2020 LT TrailBoss due to that reason. Is there something you can put over the hole of the air intake hose near the radiator? I heard a cold air intake with a water resistant cover for the filter works......

I drove through a foot of water with my 19 trail trailboss and hydrolocked mine. I'm floored. Filed with my insurance company and my adjusted told me he had 23 claims for silverados in a flood last week. Says it appears to be the design of the intake location. My 15 silverado never had a problem.

My 2018 Z71 is sitting at the shop with a possibly hydro locked engine right now. Went on a forestry road through about a foot of water and water made its way up to the CAI. Shop says it’s either a dead starter or a hydro locked motor. The water was just under my knees when I ran the tow line to have it pulled out so I find it hard to believe I killed it. When I tried to restart it, it tried to turn over at first but now nothing. Does comprehensive coverage cover hydrolocked engines?

yes, premium will go up though.

      2018 Silverado Console USB Port Not Working

      By Tbhats2130 · Posted

      My centre console USB ports haven’t been working and the one in the glovebox is starting to act up. When I plug my phone into the cord the radio will go black and stop playing, and the CarPlay is inconsistent.   I checked the fuses and they were fine. I changed the USB port out and still nothing. Hoping for some advice on what I should be looking at.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      The truck is a 1995 Chevrolet S10 Blazer, 4.3 VIN "W" engine. :cracks knuckles:   On a whim - because I needed a headache - this truck was for sale so I stopped to take a look. Doesn't run. Well, it does, but barely. Long crank, choppy idle, bad misfire(s), it REEKS of fuel. I can DO this..I'm thinking. Diamond in the rough. One owner until last year. A young guy is selling it, he bought it 6 months ago. It stranded him more than once, he's got a newborn. It was in the shop 10 days ago and he "thinks" they said it needs a new fuel injection system. He can't put any more money into it, needs it gone. I was thinking of upgrading my Macbook, which is a total want, not a need. For less than the price of a new laptop I can have fun for months tinkering on this truck and enjoying it. I'm taking this truck home. The guy was beyond thrilled, his wife was there, she thanked me profusely, I could tell they were hurting. They seemed like good people in a bind.   Some parts, a wash, maybe a set of tires, and I can have a few months of fun and then turn it for beer money (or the next project).   Sure enough, there's a work order from a shop last week in the INCHES of paperwork on this truck dating back to when the first owner bought it. They put a new distributor in it, fuel injection work describes basically opening the plenum and putting it back together. He said he couldn't afford any more work so he had them button it up and that's when he put it up for sale.   I'm not well versed in 4.3. I did discover 1995 uses the 1992-1995 SCPI "Spider" injector which is riddled with issues from splitting lines, clogged or cracked poppet valves and plastic spider legs that crumble over time. Cool. I'll just order me a ne---. Oh, the auto parts store doesn't have it? Rock Auto doesn't have it. eBay? $$$$$$ for used. These are UNAVAILABLE period end of story unless you know "a guy" who's still got one in a box somewhere.   Can't upgrade to the '96-'04 injector, it's a different plenum, wiring/pinout and sensor config.   There are a few kinda "know a guy" -guy rebuild services for these injectors out there for about $350. Okay, Okay... I'd like to know if anyone has used them? Anyone got a lead on these crappy 92-95 spiders?   I also don't want to send MY spider to Narnia and back without knowing if that's truly the problem. I guess I'll need to pull apart the plenum and do some digging.   I was also thrown for a loop. This 1995 model year truck has an OBD-II connector. The interface is decidedly not OBD-II. I can read and reset trouble codes and view live data, but there's not a lot of data. Like misfire count and on what cylinder, that's not there. It's OBD-1.5.   Nothing is ever easy. Now it makes sense why this guy wanted to disappear this thing for cheap. I'm guessing the shop told him the injector is toast, the part is unobtainable and they're not going to sort sending the thing to a rando offering rebuild service on craigslist, and the kid likely can't be without a working car for 3 weeks even if they'd facilitate that.   Experience with these early SCPI's? Stories? Things to check? Sympathy? (..Nah...)   This can sit until I sort it. But I haven't had a problem with a vehicle I couldn't easily solve in a long time.

      I have four that read by the dash 8 to 10% better than miles/pump calculations and I have one that is spot on.
