Texas Highway Patrol stopped ordering Chargers because of this issue. They are seeing issues at 100k.



Ya seen tons of those THP units being dumped online at DPS HQ in Austin lol Indiana state police are the ONLY agency with Chargers that I have seen with 200K miles ! Have to find out some day what's their secret ?? lol


Funny enough CHP ( California highway patrol) ordered like 2500 3.6 V6 current model charger's to replace their crown vics'. Apparently the HEMI Chargers where a few hundred lbs GVW past the limit for a CHP patrol car ??


On a side note they also declared the Explorer interceptors a failure and switching to Tahoe's

Starting to see some smaller agencies in South Florida getting a sprinkling of Tahoe's.

So, if it is a valve float issue, then engines not being reved high should be ok as valve float only occurs at high rpm's, right? If that is indeed the case, I almost want to buy aftermarket valve springs for my truck and get them installed.

I'd assume the SRT springs would be drop-ins

Yes, I would assume they would be. How much different could they be?

Quoting myself from another thread:

- All the non-SRT V8's share the same valve springs, part # 68080909AB
- All the V8's with MDS share the same lifters, part # 5038788AC
- The 6.4L truck engine has its own cam, part # 5045517AC
- The 6.4L SRT engine has its own cam, part # 5038419AB
- The 6.4L SRT engine uses valve spring part # 5037382BC which is also spec'd for "Police" optioned Chargers as well as the 6.2L HellKitty engine.

We have Tahoes being used by multiple agencies around here. The officers/deputies/troopers complain about how they are underpowered and have major brake fade, they don't like getting into high speed pursuits in them and let the Chargers go after the runners.

The Ram 5.7 cam and lifter failures I've read of the last year or so were mostly on higher mileage trucks.

There's a new post on a Ram forum I follow of a 2013 Ram 1500 hemi owner with 153K miles on his truck, having the cam/lifter work done to the tune of ~$3600 at a Ram dealer. He had a warranty through his credit union. so it's only costing him his $100 deductible. Claims to have done M1 oil changes every 3000mi as well.

I guess my point is, what domestic truck made beyond ~2010 or so is not going to have some expensive issue by 150K miles. They're not built to that standard IMO.

At the dealer I work at most of the failures are vehicle with extended idle hrs like police and older people.Also SRTs use 0w40 oil that might be a factor also.

The 6.4L truck engine, that also specs 0w-40, has experienced the issue.

Yeah there's a cool tool to let you do that. The spacings in my Mazda6 do not allow for use of such a labour-saving fixture.... .

Bigger agencies in my parts too. Seen quite a few BSO, Hollywood, and FHP Tahoe's. Word on the street is LEOs love them as much as they did the 9C1 Caprices. Especially K9 officers (dog and human both).

Same with the county here. Couldnt keep engines in them so are ordering Explorers now.

Most of our local LEO Chargers are V6's, so we still have a ton of them with a few Explorers sprinkled in. OPP seemed to be getting into the Tahoe but now I see mostly Explorer and Taurus.

I would love to see a breakdown of 5.7l hemi rams sold by year for 2009, 10, 11, and 12. I would also love to see a breakdown of 5.7l hemi rams that have this particular failure by year model to this point. I know that's not going to happen, but it would be nice to have an actual percentage. I would almost be willing to bet that overall, it is a small percentage.
Things like this are real problems that need addressed, but the internet and forums in general blow things like this way out of proportion, well, unless you're talking about a Chrysler 2.7l, then you better believe every bit of it! Lol

I heard rumor that we're getting Durango's instead of Chargers. I'm sure they'll start ticking just like some of the Chargers are.

If it's a hemi, it will. My 2011 had the seemingly mandatory broken exhaust manifold studs. Wonder if they FINALLY fixed the 5.7 water pump issue.

 

[GMguy84]

LOL, Oh ya the new Durango police pursuit pkg lol


With the bad stigma of the Chargers, I doubt many depts will even touch those ??


Shame GM doesn't make a mid size suv PPV like the new Blazer. NOW that will be one bad motha looking cop car lol

 

[klt1986]

Here is a picture of a lifter from one of our patrol 2011 Charger's w/ the 5.7. Happened last year and mileage was less than 100k. 3k oil changes but unsure of what brand/viscosity oil was used at our shop. Thus far it is the only one that has developed this issue.

I'm guessing this is a lot like the infamous "Pentastar head failures" of a few years back. It's blown way out of proportion by a dozen of internet forums. The fact was, <1% were affected. 1% of a million is still a significant number, but that means 99% won't have a failure. I'm on my 4th Pentastar, and 3rd 5.7 Hemi. Fingers crossed.
