Expanded wiper recall investigation

Previously NHSTA started an investigation into windshield wiper failures on 2013 Equinoxes and Terrains. This has been expanded to cover 2010 through 2016 model years after finding there were 1900 complaints for 1.7 million vehicles.

One source of this information:

https://www.carcomplaints.com/news/2...mplaints.shtml

No indication if/when a recall might occur.

Regards,
John

Probably the same plastic ball joints in the wiper transmission arms used in the Malibu. More of a wear item in the rainy states IMO

A 0.001% fail rate is deemed too high? Doesn't seem that bad to me. GM should just extend the warranty on the wiper motor to 10 yr/100,000 miles on the 2010-2016 models and be done with it.

Interesting that the 2017 is not included in the investigation since it was the last year of the old body style.

1,900 / 1,700,000 = 0.11%

This doesn't include failures that didn't get reported to NHSTA.

1% = 0.01

We are taking about a failure rate not even close to 1%.

From arcee:

1,900/1,700,000 = 0.0011%


No! 1,900 / 1,700,000 =0.0011

To convert 0.0011 to a percent multiply by 100 getting 0.11%.

Check: 1,900 / 1,700,000, drop is about 1 / 1000 which is 1 / 10 of a percent.

John

I bet those less than 1% are vehicles not very well maintained. If this was a really big issue you would have a lot more than the less than 1% having a problem. Many people don't ever put grease in the door latches and wonder why their door eventually sticks and hard to open.

I'm not going to argue with you anymore. We are both right, just looking at it in a different form. In my world, 0.11 is eleven percent, with 1.0 being 100 percent.

In any event, it is a non issue failure rate.

Arcee:

No offense, but I think I *might* see what’s going on here:

You *may* be forgetting the “rule” of converting the decimal number to a percent because, in “your world” you’re used to seeing only decimals out to two places (eg: .11, .25, .33, etc).

In all these cases, the “percent representation” just ends up being the same number (eg: 11 percent, 25 percent, 33 percent).

But then this is causing you to do the same thing with decimal numbers with *more than* two decimals places:

.0011 becomes .0011% ... which is incorrect.

I know it’s confusing, but you gotta remember the rule, or come up with a memory aid like ... “to put the percent sign on the right you must move the decimal point two places to the right”

A problem for me: While I never had a problem with a previous platform, I couldn’t remember PID algorithm “control action” on the Rockwell platform the way they presented it ... SP-PV vs PV-SP (which is the “calculated error”, and makes perfect sense - except I could never remember which Controller Action each represented).

Finally came up with my own little memory aid: “Look at the first term (SP or PV). If the letters are in alphabetical order (eg: PV), that’s a “direct-acting” PID. If they’re in reverse order (SP), that’s reverse-acting. Drove me crazy there for a while.

So much of what we do everyday relies on memory. And as we age, portions of our memory capability start to wither away. Using memory aids like I’ve described above are one way to get around this, and at least give the *appearance* that we’ve still got our fastball (LOL!)

Maintainance??

What type of maintainance would you suggest for the wiper assembly? I maintain our vehicles to a tee but have neglected to remove vowel vents or dash panels to care for the wiper assembly on the nearly 100 vehicles I've owned.
Aside from cleaning out the debris from under the arms, there's not much that can be done.
