Anyone else have this issue?

[dorkmagus]

So my wife got a new T4R a few weeks ago and when this happened it had around 900 miles on it. We took it through a car wash that we had already been through a couple times. When I was pulling out onto the road it misfired a bit and check engine and trac off lights came on. I scanned it when I got back to my shop and it had codes for 5 of the six coil packs.

I assumed something got wet even though it shouldn't have and needed to dry out. I cleared the codes and it drove fine. Later that night it did the same thing. Took it to the dealer and they say that they found a wire going to one of the coils that was rubbing the valve cover. They say they fixed the wire and swear it had nothing to do with the car wash and that it was just a coincidence. I looked and couldn't find any place where they spliced a wire. They also say they have never seen this issue before.

My wife just got her new 2017 Saturday, and they told her not to go through the car wash with the power spray, so while she was at work i had it out putting new wheels & tires on it, and decided to take it to the car wash lol. No problem. The guy said it could effect the sensors or back up camera. I thought are you shiting me, and in i went.

What codes did it have?

Auto car washes are a good cheap way to screw up any vehicle. There is no end to the number of problems they can create: scratches, dents, undercarriage damage, etc. If for some reason you can't do the work yourself, go somewhere that hand washes and or details vehicles after checking them out.

P0353, p0354, p0355, p0356 according to the paperwork. I forgot to write them down when I scanned it but I think there was one other.

And if something had gotten wet because of the car wash then I would have taken full responsibility. However, a wire that wasn't routed correctly and rubbed through on the valve cover in 900 miles is a different story.

There was a problem and Toyota has fixed it.

Specifically, what is your current problem.

Huh? Yes they fixed it. I'm just curious if anyone else had a similar issue or if mine was isolated.

 

[gm350reratliff]

Both of my 4runners have seen numerous automated car washes and I've sprayed off the engines numerous times as well with no issues.

It sounds like some wires were chaffed that grounded out when water was introduced. Most likely a isolated issue from an improperly routed harness but I would look over all the harnesses real close to make sure there aren't more wires damaged. Also, I would look real close for signs of rodents getting up there. For some reason Toyota thought it would be good to use peanut butter cup flavored wires that seems to draw in the rodents.

They say they fixed the wire....... I looked and couldn't find any place where they spliced a wire.

They would not have spliced it together anyplace. They would have just replaced the entire thing.

I take mine through the auto wash every week, for like the last 5 years. Never an issue.

I agree I took my 4r thru cruise thru once being a lazy ass. And yea after the rinse cycle I swear my hood was going to buckle with how much it was flexing. And it didn't get all the bugs off my bumper I can get it cleaner with a halfassed hand wash.

I used to take my ram all the time because I didn't really care because we were out in the desert every weekend. But before I sold it that's when I started noticing how wavy my hood has gotten and all the scratches that wouldn't buff out, never noticed from 5 feet away because the truck was silver. Also the multiple times I got a check engine light on for a evap leak when I was pulling out, couldn't figure that out until the undercarriage wash finally blew the rubber hose completely off my evap canister. Guess the under carriage wash was moving the hose enough to cause a small leak then finally blew it off. Zip tie fixed that problem from ever coming back

Electric pressure washer, foam gun, and a micro fiber shammy, and wash late afternoon takes me maybe 30 minutes tops. Same thing I used to do with my g35 or I'd take it to the car wash by work and they were forced to hand wash it because it was to low and 19x12's with a 7.5" lip and stretched tires were never going to fit on their track. Best thing is they would only charge me 4 bucks extra ound:

We take our runner and tacoma thru auto car washes all the time.

Nope they said they spliced it. Plus I'm a tech so I know how warranty works and they usually don't want to pay for jack. At least Honda doesn't. As long as it wasn't SRS related they usually have us splice. Sometimes I don't agree with it but that's how it is.

LOL. This is funny.
:rockthrow:


Scratches, dents... oh the horror.....


Have you seen what some of us do to our trucks!!!!! Car washes are the last thing we have to worry about.

The only reason I hand wash is to avoid the destruction my truck will do to the car wash.. Feel bad leaving behind rocks and mud clogging up the drains.

yeah but a car wash is just simulating at hard rain storm that you can experience on the road. minus the scratches/dents etc. The runner should be able to handle a car wash. I take mine in once a week.

Doesn't apply to this situation anyway since the issue was a coincidence.

 

[Jack19]

Nope. Take it through car washes all the time.

Sometimes the touchless found at gas stations, sometimes the full touch AutoBell types.

Never any problem.

If the vehicle can't take a simple car wash, there's a build problem.

Sooooo, if they said they spliced it and you looked and couldn't find it, that should tell you something.

At least it tells me that I wouldn't be going back to that dealer again. 900 miles on a the new rig and they are cutting and splicing coil wires to 'fix' an issue? I doubt the coil wire has enough extra length to loose an inch out of the middle and still fit the way it was designed. Something fishy is going on with that explanation.

I agree. However, I haven't had time to dig in and look closely. I really only popped the cover off the engine and looked with a flashlight. I do know that when dealing with warranty work techs can sometimes embellish the story some to get extra time. So let's say they actually found a plug not seated all the way or water in a connector, they may have said they had to "fix" the harness. Not sure if that's what actually happened. I plan on stopping back by there when I get a chance and have the tech show me exactly where the damage was.

 

[itr1275]

I've only had my t4r for a month but I find it hard to believe a car wash would do that. The reason being is I've forded 2 and 1/2 feet of water in my nearly stock Tacoma several times. No issues.

If toyota screwed it up that bad I would be surprise.

Not exactly true. If an individual wire can be repaired that is what will take place rather than replacing a $2000 wiring harness that can have potentially up to 10 hours of labor in addition to the cost of the harness. I have replaced many harnesses in my days as a technician as well as repaired many.

Like you, I also take mine through the auto wash and have not had any problems

A harness repair/splice can involve cutting out the damaged section and adding a new piece of wire to replace that damaged section thus the length of the wire is not an issue. This repair would then get taped up and re-wrapped into the original wire harness loom and not always be very noticeable. That is if the repair is done correctly.
