They'd be perfectly fine in the location they chose...if they had decided sealing the stupid things might be a good idea...

I thought I remember a thread about a year ago where the side detection sensors were just unplugged all together.

MP81- Was this your case, or someone else with a diesel? Not sure if that would get the service light on the dash to go out, but $1000 for what some people may debate is a non safety issue is a lot of money.

Nice convenience sure, worth the expense for repair I don't think so.

Yeah, we had them unplug the sensors and tie the harness up and all the issues stopped.

I am in the same boat. I originally had them both replaced in march of 2016 under warranty.
Then one side failed again in August 2017,of course not under any warranty.
Now the warning in the DIC has turned up again.

I called GM Canada and complained jus to make myself feel better.

I leasing my diesel and am not looking forward to another repair at my cost for a defective design on a car that I don't own.

Oh the joy of car ownership.

I took at look at mine over the weekend and wow, that is a horrible setup. The wiring harness connectors and sensor connectors were full of dirt and road salt. I cleaned both harness and sensor connectors out with MAF cleaner and coated the sensor connector with dielectric grease. On the wiring harness there is an opening for a white clip to slide up to remove the wires from the connector, but it leaves the whole connector open for moister. I filled that slot in with dielectric grease too. So far so good with that.

One thing I noticed is that I put mud guards on the car over the summer and I think that helped keep it somewhat cleaner. The guards are right there to block crap from flinging up into the bumper cover.

Well, after cleaning and waterproofing mine, and a few weeks of heavy rain, I no longer get the passenger side lighting up when nothing is there.

I wouldn't doubt if the poor location is impacting the sensors, considering how much dirt and grime mine had after only a year.

I'd recommend that everyone with functional sensors clean the connectors and grease them up. It might save them from failing.

I know the radar sensors are on the L and R inside of the rear bumper cover, but where is the control module? Are there any smart phone apps that read chassis codes related to this system?

There are lots of electronics exposed to moisture spray on an automobile. Sub par materials, design, or construction are the only reason for these expensive failures!

Hi everyone. Joined the site to chat about this issue. I have a 14' Chevy Cruze 2LT - And I'm up here in Sask Canada! This is my first winter with the car, and maybe about a month ago my passenger side blind spot sensor light would flash and flicker, but would work. It slowly started getting worse, to the point where maybe a week or so ago it just stopped coming on all together. Even when i started the car, the sensor light wouldn't light up on the right side. Now yesterday i got the warning "Service Detection Sensor System" or whatever it says. After reading up on the topic, i have a strong feeling this happened from water getting into the sensor, and freezing at night. As recently i have driven thru lots of puddles, and it gets well below freezing here during the night. While its a little frustrating for this to be happening, especially considering I wont have warranty to fix the issue, (got a 2 year warranty thru the used dealer) is it safe to say I can go on ignoring the issue and driving it as is? Other posters have mentioned that once this happens, things can get so much worse. Like the nav/radio/rear view camera can apparently go, among other things. I really dont want to replace the sensor because a) im young and broke b) it seems like it will eventually happen again considering where i live -- but i also dont want this issue to lead to other, more expensive repairs. Any thoughts or suggestions? Oh by the way I'm so dumb with cars i can barely spell the word haha. Thanks yall!

I know I'm bumping an old post here, but do you have any idea what was involved in the harness being tied up? I requested my dealer to do this, but they refused citing liability. Wondering if someone could somehow accomplish this themselves. Sick of replacing these things every winter right after the year parts warranty is up. May I ask what dealer did it for you?

 

[MP81]

I'd imagine just disconnecting it and wire-tying it up out of the way. There is no liability in doing this, so I'm not sure why they would not do it.

Just to provide another update. It's been just about 3 months and so far through all the rain I haven't had anymore false positive blind spot warning lights. Cleaning and insulating the connector really seems to have helped. I recommend it to anyone else having this issue.

Apparently there has been a class action lawsuit filed about this issue (it applies to 2013 to 2018 Cruzes). You can check it out here. It says that they are are "easily damaged by water, snow, dirt, and other debris". This should certainly be a special warranty repair.

I have included a picture to show what they look like. I have replaced five of these modules so far (Dec 2014, Jan 2015, Feb 2017, Feb 2017 and Feb 2018). I was still trying to figure out a way to protect them in the winter. I do not want to take them out (since they are both working right now and I am afraid that might lead to problems). I was maybe thinking of liquid electric tape around the connector, hopefully that is easy to remove if it fails. If there is a way of preventing the debris getting in these modules should last many, many years. The second picture I did not take, that was taken from another thread.

My thought on sealing them was to silicone the part split, and then silicone around the connector, with it plugged in.

But considering they should simply just be sealed to begin with...

I'm not normally one for a class-action suit, but that's one I will get behind. When we brought the car to the dealer on Monday, the tech adviser mentioned the Service Side Detection message, and I told him that we'd had the sensors disconnected and tied up after all the cluster and infotainment screen issues they caused when they both shorted out, and he said that honestly is the easiest way to deal with them - meaning it's even more prevalent than I thought.

Given the messages on this forum, GM's numbers seem low.

The service side detection system happened again on mine. I had the passenger side replaced just about 2 years ago.

Is there a way to know for certain which side is causing the problem?

Could someone pull the OHMS from a working sensor on both sides and post the values?

*EDIT*

Also, do we know if the left/right side are the same part #s?

 

[rhalo1969]

They are the same number for a 2014 Cruze.

Inspected mine today. I can't tell which one is bad. It's rained a lot here the last week and when I pulled the sensors out of the plastic frame there was a lot of water that came out with them, like it was sitting in there.

Looking closer at the sensor, as seen in the above image, it's obviously a two piece design. I bought some Gorilla waterproof tape. I'm just going to pick up 2 new sensors and seal the edges with the tape and seal the wire harness connectors.

Do we know if these things can just be plugged in or do they require being programed?

Judging by the internal debris noise mine makes when I shake one of the units, I assume the inside of it looks like the original picture posted here of the corroded internals.

For you guys just disabling this, is just unplugged the sensors all you need to do to get rid of the error? Not even the initial startup error?

Unplugging them removes the consist service message popping up while driving if the module is on the verge of failure and just causes an initial service message on startup, it will not pop back up again until next startup. It will however pop up on every startup unless some way is found to program it away.
