James’s 2005 Impala: He Wrote to Chevy First

James Brooks is an engineer in the West Palm Beach area of Florida, and before he found us he did what an engineer does: he went to the manufacturer, documented the problem, and asked them to fix their product. His July 2016 story about his 2005 Chevy Impala includes their answer.

95 degrees, and the car says no

“Imagine this, It is 95 degrees outside and you get into the car and it will not start because of a security feature. This is what I use to deal with, very frustrating to say the least. I called a local dealership and they said it would be $800 and they could only guarantee the work for 1 year, not acceptable!”

Read that dealer offer as an engineer would, the way James did: $800 to replace failing components with identical components, warranted for exactly one year because everyone involved knows the replacement inherits the same design.

The letter to Chevrolet

“I sent an email to Chevy explaining this is a major problem and there are numerous cases of this causing issues and I asked them to simply ‘google’ it so see the issue, they explained that ‘googling’ issues is not allowed. The note basically said they should focus on their quality, and as an engineer I was not impressed with the quality and I would not buy another car from them if the next car had this issue. Long story short they did not do anything about it, and that is when I found the PRO Module!”

We want to be fair to whoever wrote that reply: a support agent following policy, no doubt. But the policy is the point. The failure James was describing fills forums, and the official channel was not permitted to look. That institutional blindness is a large part of why this company exists.

A year before he would say a word

“It has worked GREAT and the installation is very easy! I am not quick to give reviews due to the fact, it could be a fluke or short lived but I have now had the module installed for a year and have had ZERO problems, I would recommend this product to anyone, and I already have! If you are experiencing this problem and are considering this product just buy it, do not suffer any longer!”

An engineer who withheld his review for a full year of testing is our kind of reviewer. He is also the third person in this archive to report the same thing across a year or more: Eric Knowlton across two and a half years, Matt Salmons across four, and James across one. The fix does not degrade, because there is nothing left in the circuit to degrade.

If you have one of these cars

James’s 2005 Impala is covered by the 2000-2005 Chevrolet Impala and Monte Carlo installation guide, the same wiring that fixed Kristina’s and Christopher’s cars. Heat makes a marginal Passlock sensor worse, which is why Florida features so often in these stories, and why the NEWROCKIES PRO Module ends it regardless of the forecast.
