NHTSA upgrades probe into 1.7 million GM vehicles over wiper failures

WASHINGTON — The U.S. National Highway Traffic Safety Administration (NHTSA) said Tuesday it is upgrading an investigation into 1.7 million General Motors vehicles for windshield wiper failures. The auto safety agency opened the probe in November 2018 to see if GM needed to expand a 2016 recall of 2013 model year Chevrolet Equinox and GMC Terrain SUVs to cover additional vehicles. The engineering analysis probe covers 2010-2012 and 2014-2016 Equinox and Terrain vehicles. NHTSA could demand a recall after it completes the probe. NHTSA said it has reviewed 1,900 complaints and reports related to the issue in the 1.7 million vehicles. NHTSA said it has seen elevated failure rates in the 1.7 million vehicles, even though GM said the recalled vehicles have "double the warranty rate and five times the complaint rate." GM said it will "fully cooperate to support their investigation. We do not believe these windshield washer systems are defective." The wiper failures that prompted the 2016 recall were attributed to water and debris intrusion into the windshield wiper assembly ball joints, leading to excessive wear and eventual detachment of the ball joint. GM said it was installing an improved windshield wiper motor and transmission assembly and relocating a drain hole at the base of the windshield. Related Video:

How easy is it to rebuild a Chevy small block V8?

Chevrolet's famous small block V8 stands as one of the workhorse engines in American auto history, with its variants going into vehicles from hot rods to pickup trucks. But do you know that you can fully disassemble and completely restore one of these mills in just under four minutes? Well, as long as there's some assistance from time-lapse photography, that is. Hagerty created this short clip showing a dirt-covered small block turning from a frog into a prince. Thankfully, the time-lapse doesn't speed the process up too much, and it's still easy to see how all of the principal parts fit together. With all sorts of sensors and software helping to drive the modern automobile, viewing the internal combustion engine in its purely mechanical form is still fascinating. Related Video:

GM recalls Cadillac ATS and Chevy Impala for separate issues

The National Highway Traffic Safety Administration added two recalls from General Motors in the government organization's daily update of safety campaigns. Both were for failing to meet Federal Motor Vehicle Safety Standards but for completely separate reasons. The larger recall covers 58,698 units of the 2013-2015 Cadillac ATS, but it doesn't really carry huge safety concerns. In vehicles produced between April 25, 2012, and February 9, 2015, the controls for the tilt and slide of the moonroof are not recessed enough, as required by federal law. According to NHTSA, it's possible that someone could inadvertently activate the auto-close for the roof panel, which the agency claims increases "the risk of personal injury." Dealers will install a new trim plate that will add the necessary clearance. The other campaign covers 1,177 examples of the 2014 Chevrolet Impala from between November 15, 2012, and May 27, 2014. However, this is actually a repeat of a previous recall on the Chevy and the Cadillac XTS from 2014. The affected Impalas here "were remedied incorrectly" under the earlier campaign, according to NHTSA. On these sedans, it's possible the electronic parking brake might not fully disengage and still remain in some contact with the rotor, which is in violation of federal rules. The fault can cause excessive heat from the brakes that could potentially lead to a fire, according to NHTSA. To fix the problem, dealers will reprogram the electronic parking brake control module.

In the affected vehicles, the power-operated roof panels auto-close when the non-recessed "Slide" or "Tilt" switches are pressed. As such, these vehicles fail to comply with the requirements of the Federal Motor Vehicle Safety Standards (FMVSS) No.
