The pain just keeps on coming for Toyota. First came complaints of cars running away without the driver pressing the accelerator.

toyota extinde problema franelor la prius la nivel global, rechemand in service 437.000 de priusuri. Vad ca la toyota mai nou, e saptamana si recall-ul

Toyota says it is recalling about 437,000 Prius and other hybrid vehicles worldwide to fix brake problems — the latest in a string of embarrassing safety lapses at the world's largest automaker.

"I don't see Toyota as an infallible company that never makes mistakes," President Akio Toyoda said at a press conference Tuesday in Tokyo. "We will face up to the facts and correct the problem, putting customers' safety and convenience first."

With the Prius announcement, the number of vehicles recalled globally by Toyota Motor Corp. has ballooned to 8.5 million, including for floor mats which can trap gas pedals and faulty gas pedals that are slow to return to the idle position. The 2010 Prius wasn't part of the earlier recalls.

There have been about 200 complaints in Japan and the U.S. about a delay when the brakes in the Prius were pressed in cold conditions and on some bumpy roads. The delay doesn't indicate a brake failure. The company says the problem can be fixed in 40 minutes with new software that oversees the controls of the antilock brakes.

"Let me assure everyone that we will redouble our commitment to quality as the lifeline of our company," Toyoda said.

Toyota officials went to Japan's Transport Ministry earlier Tuesday to formally notify officials the company is recalling the 2010 Prius gas-electric hybrid — the world's top-selling hybrid car. The automaker is also recalling two other hybrid models in Japan, the Lexus HS250h sedan, sold in the U.S. and Japan, and the Sai, which is sold only in Japan.

The 223,000 cars being recalled in Japan include nearly 200,000 Priuses sold from April last year through Monday, according to papers the automaker filed with the ministry. The Prius is Japan's top-selling car.

In the U.S., Toyota will recall 133,000 Prius cars and 14,500 Lexus HS250h vehicles. Nearly 53,000 Priuses are also being recalled in Europe. Toyota is suspending production of the Sai and Lexus HS250h in Japan until the updated software for those models is ready.

If drivers experience a delayed reaction when depressing the brakes in any of these models, they should keep pressing, according to Toyota and the transport ministry.

The Prius repairs will start in Japan on Wednesday. U.S. owners will start receiving letters about the recall next week.

Toyoda, the president, has been criticized for being largely invisible during the two weeks after the company announced Jan. 21 the gas pedal recall in the U.S., Europe and China.

He apologized at his first public press conference last Friday, but was criticized by the Japanese media for failing to outline concrete steps to tackle the safety crisis and reassure customers around the world.

In contrast to his halting English in response to questions from foreign reporters at last week's news conference, Toyoda seemed much better prepared Tuesday, reading from an English statement after doing so in Japanese.

"We will do everything in our power to regain the confidence of our customers," Toyoda said.

He said he planned to go to the U.S. soon to talk with American workers and dealers to bring the ranks together.

Analysts said fears of an even bigger consumer backlash prodded Toyota into recalling the Prius.

"If they hadn't done the recalls, their image would have suffered even more," said Ryoichi Saito, auto analyst at Mizuho Investors Securities in Tokyo.

The Japanese transport ministry rapped Toyota as reacting too slowly, and said he was meeting U.S. Ambassador to Japan John Roos Wednesday to exchange views about Toyota's recalls and make sure U.S.-Japan relations remained on good terms.

"The consideration for customers was lacking in Toyota," Seiji Maehara told reporters, after a meeting with Toyoda. "We hope this never happens again."

Toyoda, who visited the minister after his news conference, apologized and explained the recalls, Maehara said.

U.S. safety officials have launched an investigation into problems with the brakes.

The problem is suspected in four crashes resulting in two minor injuries, according to data gathered by the National Highway Traffic Safety Administration, which is investigating the matter. Toyota says it's cooperating with NHTSA's investigation.

Problems with hybrid braking systems haven't been limited to Toyota.

Ford Motor Co. said last week it plans to fix 17,600 Mercury Milan and Ford Fusion gas-electric hybrids because of a software problem that can give drivers the impression that the brakes have failed. The automaker says the problem occurs in transition between two braking systems and at no time are drivers without brakes.

Toyota's plug-in hybrid is also being recalled in Japan, Europe and the U.S., but in small numbers because it is a largely experimental model for rental and government use.

The Prius holds a cherished spot in Toyota's vehicle lineup and is symbolic of its leadership in the "green" car market.

The Toyota executive overseeing quality Shinichi Sasaki said the delay that Prius drivers can feel when braking lasts for a fraction of a second as the antilock brakes kick in.

The problem happens only on snowy or bumpy surfaces, and the complaints did not become more numerous until recently when the weather got colder, Sasaki said.

But Toyoda acknowledged the company could have done better in picking up on the complaints, managing the crisis and sending a message to car owners on a fix.

In the U.S., Toyota will add five more centers in addition to the current three that investigate customer complaints, Sasaki said.

"When compared to the size of Japan, America is so much bigger and so our network for gathering information was not enough," he said.

Toyota was one of the first companies to mass-market a hybrid that combines an electric motor with a gas engine, introducing the Prius in Japan in 1997. Its high gas mileage made it popular among environmentally conscious drivers, especially when gas prices spiked two years ago.

But the complexity of the Prius, a highly computerized car, has led to problems in the past. In 2005, the company repaired 75,000 of them to fix software glitches that caused the engine to stall. It has also had trouble with headlights going out.

Shares in Toyota rose 2.9 percent Tuesday to 3,375 yen, but are still down about 20 percent since Jan. 21, when it announced the gas pedal recall.

O sa le ia ani buni sa recastige increderea cumparatorilor. Chiar daca rechemarile sunt facute sa incerce sa-si pastreze renumele, au pierdut prea mult.

O sa le ia ani buni sa recastige increderea cumparatorilor

Problema este de mentalitate, nu de incredere. O urma de indoiala este aruncata acum si pe restul de producatori japonezi. Daca si ei au ascuns ceva?

Pai pana acum, stateau linistiti doar erau intr-o masina a constructorului NR 1 din punct de vedere al calitatii. Chiar daca se auzea vreo troncanitura mai degraba se gandea ca are halucinatii auditive decat sa banuiasca masina ca ar avea vreun defect. La fel cum se creeaza mitul alora care invata bine la scoala, daca ai luat de 2-3 ori nota 10 te invata profesoru si chiar daca nu ai invatat bine de cateva ori tot este subiectiv si iti da o nota mai mare pentru ca te stie ca inveti bine.

toyota suspenda productia Toyotei Sai, Lexusului HS250h,de pe data de 13 februarie datorita problemelor de franare..

2010 toyota sai 04 Toyota Sai/Lexus HS250h : production suspendueDotées des mêmes technologies de freinage que la Prius (dont on ne rappellera pas le vaste rappel lancé à l’échelon planétaire), les Toyota Sai et Lexus HS250h enregistrent, contrairement à la première nommée, un arrêt de leur production d’une durée d’une semaine annonce le constructeur nippon. Si le défaut avait été détecté en décembre sur la Prius, puis corrigé en usine début janvier (n’entraînant pas de pause dans la production), les modifications nécessaires sur les Toyota Sai et Lexus HS250h n’ont pas encore été appliquées.

“Nous avons décidé de suspendre la production des deux modèles du 13 au 20 février“, s’est exprimé un porte-parole de Toyota ajoutant que cette pause” pourrait être prolongée si nécessaire“.

Explication concernant cette interruption des chaînes de production ? “Nous n’avons pas encore terminé les préparatifs pour effectuer les changements nécessaires“, indique le porte-parole. Selon certains médias nippons, cette pause forcée se traduirait par la non production de quelques 2 000 unités.

Cette nouvelle annonce fait suite à celle touchant la suspension des ventes de ces deux modèles ainsi que le rappel de plusieurs milliers d’exemplaires dans le monde.

pana la urma metoda lor de a ascunde defecte de fabricatie cu schimbari in perioada de garantie, pe sustache, isi spune cuvantul....

o sa fie interesant cum o sa isi revina.... eu sper prin reduceri masive de pret....

inca un recall toyota, astia vad ca au ambitia ca la fiecare saptamana sa mai faca un recall la masinile lor


Toyota recalling 8,000 2010 Tacoma 4WD pickups over driveshaft defect

In a dealer communique sent out today, Toyota has announced the voluntary recall of some 8,000 2010 Tacomas that could suffer from a defect in the front propeller shaft.

Pickuptrucks.com reports that a crack can form in the rear joint, causing the driveshaft to come loose from the truck. Obviously, this defect will only affect four-wheel drive models, so standard two-wheel drive Tacomas are left out of the recall.

According to Brian Lyons, Toyota's head of safety communications, "Most of the vehicles [included in the recall] are in the pipeline in Toyota's distribution system or on dealer lots."

Affected owners can contact Toyota at 1-800-331-4331 for more information, and Toyota dealers will perform a ten minute visual inspection of the trucks. Naturally, if they find a fault with the prop shaft assembly, it will be replaced free of charge.

Este si asta un fel de a-ti face reclama, i guess )

Lupta pentru vanzari in crestere a condus la autoturisme defecte.

Toyota - peste 4 milioane de masini defecte


Problema semnalata in SUA la unele modele Toyota si aflata in prezent sub investigatie si in Europa se refera la faptul ca exista posibilitatea ca pedala de acceleratie sa ramana blocata mecanic intr-o pozitie partial apasata sau sa revina lent la pozitia normala.

Constructorul auto japonez Toyota Motor Corp, care a fost vazut mult timp ca un leader in industria auto pentru calitate, a oprit in ianuarie comercializarea celor mai populare 8 modele in America din cauza defectelor constatate, potrivit Wall Street Journal.

In America, au avut loc 2.274 de incidente cu autoturisme Toyota, provocand 275 de accidente, soldate cu 18 morti.

Toyota le-a spus dealerilor din America sa nu mai comercializeze, sedanurile Camry si Corolla, SUV-urile RAV4, Highlander si Sequoia, autoturismul pick-up Tundra, masinile Matrix si Avalon.

In 2009, cele 8 modele au adus 57% din vazarile realizate de Toyota pe piata americana.

Toyota a rechemat in ianuarie 2,3 milioane vehicule in SUA din cauza problemelor cu pedala de acceleratie, dupa ce in noiembrie 2009, au mai fost retrase in SUA circa 4,2 milioane de autoturisme.

In Europa, Toyota se asteapta ca aproximativ 1,8 milioane de masini sa ajunga la service pentru verificari. Printre modele se numara Aygo, iQ, Yaris, Auris, Corolla, Verso, Avensis si RAV4, produse dupa 2005.
Grupul auto Toyota a anuntat ca a identificat in Africa, America Latina si Orientul Mijlociu circa 180.000 de autoturisme echipate cu acelasi tip de pedala care a provocat probleme in America de Nord si in Europa, insa nu a decis inca rechemarea acestora in service.

Toyota a identificat 40.000 de autoturisme cu probleme de acest fel in Orientul Mijlociu. Este vorba despre modelele Avalon produse intre 2005 si 2010, si Sequoia, produse intre 2009 si 2010. De asemenea, au fost identificate 80.000 de masini in Africa si 60.000 in America Latina.

Defectele masinilor japoneze constate recent au scazut imaginea marcii Toyota, dar si vanzarile pe majoritatea pietelor.

is curios ce parere are ironick de rezultatele obtinute de noul rav4 la crahsh-test-ele iihs:

When the Insurance Institute for Highway Safety tested a batch of SUVs in its small overlap frontal crash test earlier this year, it held off on putting the Toyota RAV4 in the blender because the new, 2013 model was due to arrive shortly after the test. The new crossover might be better than it was before, but it could still only manage a rating of "Poor" in the test that has been a bugbear for a number of manufacturers.

Among other issues, the IIHS noted that the steering column moved seven inches to the right causing the crash test dummy to practically miss the airbag, the dummy's left foot was trapped in deformed sheetmetal and the dummy's head hit the instrument panel.
