US closes probe into 2 million Nissan vehicles without seeking recall
WASHINGTON :A U.S. auto safety agency on Wednesday closed a seven-year-old investigation into 2.03 million Nissan Motor vehicles over issues related to rear suspension control arm failure without seeking a recall.
The National Highway Traffic Safety Administration investigation, which covered 2013-2018 Nissan Altima and 2016-2018 Nissan Maxima vehicles, was opened in 2018 and upgraded to an engineering analysis in 2019.
The probe reviewed whether the lower control arm of the rear suspension system could separate from the chassis due to corrosion posing safety risks.
Nissan implemented a design change in January 2018 to improve the durability of the lower control arm. Nissan did not immediately comment on Wednesday.
NHTSA said it reviewed about 1,300 reports of the issue and a small number of complaints suggested they had been in near crashes. Just one complaint said a vehicle made physical contact with another object, bumping into the trailer hitch of a truck.
"Nissan acknowledges that a crack can develop in affected control arms due to stress loading from normal use and that salts commonly used for roadway snow and ice treatment may result in corrosion that exacerbates the progression of the crack," the agency said.
Most reports occurred in salt-belt U.S. states prone to corrosion issues with vehicles averaging over 113,000 miles (181,856 km) at the time of failure. No injuries have been reported.
More than 47,000 vehicles were repaired with a new part under a Nissan customer satisfaction campaign announced in 2019 and some vehicles received a warranty extension to 10 years.
"With a declining trend of reports and Nissan's actions to implement a countermeasure and extended warranty coverage, further investigation of the issue does not appear to be warranted at this time," NHTSA said.

Tesla asked to delay robotaxi launch by Democratic Texas lawmakers
A group of Democratic Texas lawmakers has asked Tesla to delay its much-anticipated robotaxi launch in Austin until September, when a new autonomous-driving law is scheduled to take effect. The group of Austin-area lawmakers said in the letter sent on Wednesday that delaying the launch, which CEO Elon Musk said could "tentatively" happen this Sunday, "is in the best interest of both public safety and building public trust in Tesla's operations." If Tesla decides to move forward with a launch this month, the lawmakers asked that Tesla respond with "detailed information" demonstrating how Tesla will comply with the new state law when it launches. Musk last year staked Tesla's future on autonomous-driving technology as it pivoted away from chasing rapid growth in electric-vehicle sales. Tesla did not immediately respond to a request for comment on the letter. It is unclear how much weight a letter from Democratic lawmakers will carry in a state where Republicans hold the governorship and majorities in both legislative chambers. Musk announced in January that Tesla would be offering "autonomous ride-hailing for money in Austin, in June," and since then the Austin rollout has been closely watched by investors and analysts - many of whom attribute the majority of Tesla's stock market value to hopes for robotaxis and humanoid robots the company has yet to deliver. Current Texas law allows autonomous-vehicle firms to operate their vehicles anywhere in Texas, as long as the vehicles meet basic registration and insurance requirements. The new legislation, which passed the Texas legislature last month and has not been signed by the governor, would for the first time require autonomous-vehicle companies to apply for authorization to operate in the state. It would give state authorities the power to revoke permits if they deem a driverless vehicle "endangers the public." Firms are also required to provide the state information on how police and first responders can deal with the vehicles in emergency situations. Musk and Tesla have given few details about their plans for the Austin robotaxi launch. The CEO has said the Austin rollout would begin with 10 or 20 Model Y vehicles, and that the company will begin operating in 'only the parts of Austin that we consider to be the safest.' Musk and Tesla have not said who the passengers will be, how Tesla will charge for rides, where in Austin they will operate or how extensive remote monitoring and operation of the vehicles will be.

Waymo brings its cars to NYC for testing, applies for autonomous driving permit
Alphabet's self-driving unit Waymo said on Wednesday its vehicles will be back in New York City next month for autonomous testing, as it continues to scale operations in the U.S. The race to deploy robotaxis is picking up pace as Waymo expands testing and Tesla prepares to begin limited trials of its autonomous taxi service with as few as 10 cars this weekend — a sign of growing momentum in self-driving vehicle development. Waymo has applied for a permit from the New York City Department of Transportation to operate autonomously, with a trained specialist behind the wheel in Manhattan. "This is not an expansion, but we have every intention of bringing our fully autonomous ride-hailing service to the city in the future," Waymo said. Waymo will start by manually driving in the city until it gets the permit. If granted, it would be New York City's first testing deployment of autonomous vehicles. New York State law does not currently allow operating a vehicle with no human behind the wheel and Waymo said it is advocating for a change to the law. The company had previously brought its cars to Manhattan in 2021 for manual driving, data collection and testing. Waymo on Tuesday said it will expand into more areas of the San Francisco peninsula and parts of Silicon Valley. Last month, it received approval from California to expand operations. As the only U.S. firm to run robotaxi services with paying passengers, Waymo has more than 1,500 vehicles, running over 250,000 rides a week across San Francisco and Los Angeles in California, Phoenix in Arizona and Austin in Texas.
