(Bloomberg) -- Toyota Motor Corp. made its fourth global recallinvolving more than a million vehicles this year, as the world’slargest automaker begins operating with stricter supervision oversafety from U.S. regulators.

The carmaker is calling back 1.75 million vehicles, including759,000 Toyota and Lexus sedans to repair fuel pipes that couldleak and raise fire risks. While the automaker may accrue hundredsof millions of dollars to pay for the recall, “the cash risk willbe much less” because not all customers will get the repairs, saidDavid Whiston, an equity analyst with Morningstar Inc. in Chicago.The company didn’t provide an estimated cost for the recalls.

“A single initial report cannot identify a trend and rarelyprompts a recall,” said Dion Corbett, a spokesman, noting that thefirst report of a problem with these cars came from the U.S. inJune 2010. “When we see what might be a trend and investigate theissue, and when we believe there is a safety-related defect, webegin a recall.”

Automakers are under increasing pressure to hasten their recallprocess and justify the time lag between learning about potentialflaws and calling back cars for fixes. The scrutiny has intensifiedafter General Motors Co. took more than a decade to start replacingdeadly ignition switches in some of the record 30 million cars andtrucks the company has recalled in North America this year.

‘Just in Case’

“Carmakers have changed their attitude and recall anyway as longas the problem is happening with multiple vehicles,” Koji Endo, aTokyo-based auto analyst at Advanced Research Japan, said bytelephone. “Just in case.”

Toyota said it isn’t aware of fires, crashes, injuries orfatalities caused by the flaws in the vehicles it’s recalling. Thefuel pipe fix involves Toyota Crown, Crown Majesta and Mark X carsand Lexus IS, GS and LS sedans built from January 2005 to September2010.

The recall announcement by Toyota yesterday involves two otherdefects. The company first received reports in July 2011 from Japanof brake fluid leaks that could lead to reduced performance. Theother safety campaign, which also involves a fix to fuel systems,follows an initial report from Japan in January 2013.

The recall is the first major global campaign by Toyota sinceDavid Kelley, a New York-based partner at Cahill Gordon &Reindel LLP and former U.S. Attorney, was appointed by the U.S.Justice Department in August to supervise the carmaker’s safetyprocedures.

‘Lessons Learned’

Kelley will review Toyota’s policies and verify the accuracy ofits public statements for three years as part of the automaker’s$1.2 billion settlement related to its handling of more than 10million vehicles recalled in 2009 and 2010 for problems that causedunintended acceleration.

Toyota has now recalled about 5.3 million vehicles in the U.S.market this year, according to its website. A total count forvehicles recalled globally wasn’t immediately available, Corbettsaid.

“With the lessons learned from past recalls in North America,Toyota keeps showing the attitude to proactively recall and haveeverything under control before any serious accident happens,” saidTakashi Aoki, a Tokyo-based fund manager at Mizuho Asset ManagementCo. “I don’t think this recall would damage the brand image, orcause the shares to decrease, as there were no injuries, fatalitiesor crashes.”

Toyota’s shares rose 0.2% to close at 5,990 yen in Tokyo,underperforming the Nikkei 225 Stock Average’s 0.9% gain. Thecompany’s American depositary receipts slid 1.5% to $109.95 at11:04 a.m. New York time.

Japanese Crowns

In Japan, China and other markets in Asia, Toyota said yesterdaythat it’s calling back about 802,000 Crown, Crown Majesta, Noah andVoxy models made June 2007 to June 2012. The company will replace arubber seal in the brake system that could crack and cause fluid toleak, leading to degraded performance.

Toyota also recalled about 190,000 Rumion and Auris cars inJapan to replace emission-control units that could cause fuel leaksand lead to greater fire risk.

In the years after its unintended-acceleration recalls, Toyotahas sought to repair its reputation for quality that helped itbecome the world’s top-selling automaker. While the Toyota City,Japan-based company lost that title to GM in 2011, it regainedleadership for each of the past two years and clung to its leadover Volkswagen AG through the first half of 2014.

“The reputational damage from the accelerator issue is done,”said Whiston, the Morningstar analyst, who rates Toyota a hold.“The more recalls we have now will numb the consumer, to anextent.”

More Investigation

Toyota may still not be done dealing with problems involvingunintended acceleration. The U.S. National Highway Traffic SafetyAdministration last month said it would evaluate an owner’s claimthat “low-speed surging” contributed to an accident with a ToyotaCorolla. As many as 1.69 million cars from model years 2006 to 2010could be subject to investigation depending on the regulator’sinquiry.

Toyota expanded a 14-month-old recall of more than 2 millionvehicles for faulty air bags in June after supplier Takata Corp.told customers further fixes may be needed.

In April, Toyota called back more than 6 million vehicles forfive potential hazards involving almost 30 models. The companyrecalled 1.9 million Prius hybrids to update software and fixdefects that could cause the cars to lose power or shut down andstop in February.

“This recall is generally not that big of a deal,” Whiston said.“Reputation only tends to be an issue when people die and Congressgets involved.”
