Right now. Announcer from nbc news World Headquarters in new york this is nbc nightly news with lester holt. Good evening. They are just 14 but also experienced at sea. And that is giving hope to the families who are the object of a massive ocean search under way right now off the coast of florida. The boys went missing on friday after setting out alone on a fishing trip believed to be to the bahamas. Their 19foot boat was found capsized and adrift in a strong current yesterday, but there have been no signs of the boys. Late this afternoon the coast guard provided an update on the expanding search. Our Kerry Sanders reports now from jupiter, florida. Just confirmed nobody is on board. Reporter in the desperate search for two missing teens, a discovery both grim and hopeful. Their capsized boat. But no sign of 14yearold perry cohen and his best friend austin stephanos. Its terrifying to know that your child is out there without you and if they need help that you cant reach out your hand and give them the help that they need. Reporter the teens set out friday from jupiter, florida on a 19foot singleengine boat with 25 gallons of fuel believed to be headed to the bahamas, only 44 miles away. But this squall captured on another boaters cell phone on friday may have caught the young mariners off guard. I call him my macgyver. He can make something out of anything. He is so strongwilled. Reporter the capsized boat was found 67 miles offshore and 170 miles north of where they departed. It was caught in the gulf stream a constant current that flows four to six Miles Per Hour this time of year. And when a person is in the water, youre basically looking for a chest up. So its a relatively small object. Reporter the boys mothers say its unlikely they were wearing their life vests when they capsized unless they knew they were in trouble. Thats because most boaters in florida, while they have the safety gear on the boat they rarely wear it because its so uncomfortable in the florida heat. The boys families and friends walked the beach here today, urging folks in north florida and georgia to do the same. Among those helping, neighbor and football great joe namath whos offered 100,000 reward for information. We just keep on looking until we get an answer. Tonight, caught in the gulf stream the boys could now be off the coast of georgia. One up side working on their behalf the water temperatures here are in the mid 80s. Lester . Kerry sanders off the coast of florida tonight. Thank you. Another big story were following here one of the worlds biggest car makers Fiat Chrysler is being ordered to make an offer to hundreds of thousands of customers to buy back their vehicles because of the dangers they pose on the road. Nbcs tom costello reports. Reporter crash test video of a deadly defect. A jeep libertys rearmounted fuel tank rupturing on impact. But on the right no rupture after a jeep is fitted with a trailer hitch to protect the tank. Consumer advocates estimate as many as 270 people died in fiery jeep crashes including a 4yearold who died in this crash. Today the government said Fiat Chrysler had acted far too slowly in ordering 23 recalls and fixing 11 million defective vehicles including the liberty and other models. Have people been put at risk because of Fiat Chryslers actions . We think so. We think this is a classic case where there is in some cases a remedy available that consumers dont know about. Reporter chrysler today hit with a record fine of up to 105 million and ordered to buy back half a million vehicles including certain 2008 through 12 dodge suvs and the topselling dodge ram pickup and provide cash to customers trading in or fixing those jeep grand cherokees and jeep liberty models. For many years manufacturers could get away with these kinds of things. We saw it with all manufacturers. Chryslers the next one on the block and theyre paying the price for it now. Reporter the price could be high. Hundreds of millions of dollars. In a statement the company says it agrees with the governments order and we also accept the resulting consequences with renewed resolve, to improve our handling of recalls and reestablish the trust our customers place in us. Its also agreeing to four years of independent oversight into how it handles recalls. If you own an affected vehicle chrysler is supposed to reach out to you directly. You can also contact your dealer but they may not have the details right away. The complete list of affected vehicles on our website at nbcnews. Com. Lester . All right, tom, thanks. Meantime nbc news is Digging Deeper tonight into the largest auto recall in u. S. History. Youll recall those defective takata airbags in 34 million vehicles linked to at least eight deaths and over 100 injuries. Well as drivers rush to have them replaced nbc news has found cars that could have these dangerous airbags driven right off the rental car lot. As our National Investigative correspondent jeff rossen explains. Reporter when some recalled airbags go off, this could happen. A violent explosion. Shrapnel sent flying. So are there rental cars out there right now with that defect . Imagine driving with your family right now and having no idea about this open recall. Scary. Reporter were scanning the most popular companies. Here we go. Heres another one. Reporter our nbc producers check the vehicle identification numbers, or vins, against a government database. Looks like we found one. Reporter at this dollar rentacar we get a hit on this ford mustang. Recall status is incomplete. One of the airbag recalls. Reporter but they rent it to us anyway. Youre all set. Straight out at the gate. Reporter at avis we spot another mustang with an airbag recall. Here we go. Ive got keys to another one. Reporter we drive off, no questions asked. Sign right there for me please. The key is inside. Reporter and watch what happens at this hertz location. We find two mustangs with the recall ready to rent. And that cars safe and everything right . Yes. All the cars are safe. Reporter jeff rossen from nbc news. Hi how are you . Reporter when we return the car at dollar i alert the manager. It has an open recall on it for that takata airbag defect. The potentially deadly one. Im not quite sure about that but ill certainly refer it to our Corporate Headquarters and check on it for you. But again, i apologize. Sow wont rent this to anybody else until its fixed . Absolutely correct. Reporter avis makes the same promise. Well sideline the car. Reporter and at hertz we found both of these cars that we rented from you have an open airbag recall. And you rented them to us. Could you just turn off the camera for us . Are you going to take these cars out of service . Could you please turn the camera off first . Reporter they end up taking the cars out of service to be inspected. The companies later telling nbc news they ground and remove cars when they get the official safety recall notice and they had not received them. But documents obtained by nbc news show the manufacturer in this case ford sent out not one but two unofficial advance recall notices over a month ago. Hertz and dollar acknowledging they received that notice but they didnt pull the cars because as policy they wait for the official notices. Tonight as a result of our investigation hertz, dollar avis and budget all telling nbc news they are now removing the affected cars with open recalls nationwide. They say safety is paramount. By the way, experts say you should check the vin number of every rental car, even the car you own, before you buy it. We have an easy link on our website right now, lester, nbcnightlynews. Com. All right, jeff thanks very much. Thousands of structures many of them homes, are under threat right now in the west as more than 20 large wildfires burn out of control in five states. Just this year 5 1 2 million acres have burned. Thats about the size of new jersey. And were still early into this fire season. Nbc News National correspondent Miguel Almaguer has more on the desperate struggle to stop the flames. Reporter tonight in california the golden state is seeing red. During the last week 270 new wildfires here. 5,000 firefighters are on the front lines. The biggest threat they face in northern california. The socalled lowell and rag fires torching nearly 9,000 acres, threatening homes like michael martinos. I have to just commend all the firefighters and people who are doing a great job to save as much as they can. Reporter feeding on tinderbox conditions exploding without warning, four fievts were caught in the flames. One suffering serious burns. Weve seen very very aggressive fire. Conditions are dry. Fires are burning much quicker than they normally do. Reporter in bend oregon crews are trying to stay ahead, burning what they can now. Almost as a prevention technique. But yeah, were using fire to fight fire. Reporter eliminating dead trees and shrubs. The perfect fuel for fire. After years of drought this forest is ready to burn. Its dryer than ever. Officials say even a controlled burn like this one can be dangerous. While more land is burning, homes are not. Many have been saved in a series of close calls. But this fire season is still young. Crews know one small spark can instantly blow a fire out of control. Miguel almaguer nbc news bend oregon. Lets turn to politics now. With just ten days to go until the very first republican president ial debate donald trump is now leading the race in New Hampshire with second place jeb bush trailing him by seven points. And in iowa trump is running a close second behind scott walker. And with 16 candidates competing for a spot on the debate stage, the war of words is escalating. Nbcs Peter Alexander has the details. That sense of stability reporter jeb bush today winced at the latest republican attack line. I think we need to tone down the rhetoric for sure. Reporter reacting to Mike Huckabee who over the weekend asserted that president obamas Iran Nuclear Deal could lead to another holocaust. He would take the israelis and basically march them to the door of the oven. Reporter late today huckabee refused to back down. I have stood at that oven door. I know exactly what it looks like. I will not apologize and i will not recant because the word holocaust was invoked by the iranian government. Reporter among those offended president obama. Would be considered ridiculous if it werent so sad. Reporter competing for attention, republican rivals are trying to outtrump trump. And then i watch this idiot Lindsey Graham hes a war hero because he was captured. I like people who werent captured. Theyre rapists. And some i assume are good people. Reporter even before huckabee several candidates resorted to political stunts. Rand paul torching the tax code. Lindsey graham smashing his cell phone after trump gave out his number. The horse race is on but the track is muddy. Trying to keep the peace, Republican Party chairman reince priebus, speaking this morning exclusively on today, going out of his way not to criticize trump. Hes speaking to people who are really frustrated with washington. The pressure on these candidates is to ratchet up the rhetoric be confrontational. What doesnt work . I think what doesnt work is being thoughtful serious, dispassionate, and president ial. With all the infighting 6 in 10 americans now say they have an unfavorable view of the Republican Party. Lester . Peter alexander. And this program note. President ial hopeful governor Mike Huckabee will be live tomorrow morning on today here on nbc. Turning overseas where sources tell nbc news that turkey is getting into the fight against isis teaming up with the u. S. In a plan to eradicate isis fighters near turkeys border with syria. There are no u. S. Service members in the ground war but there are americans whove left everything behind to join the fight against isis. Our keir simmons was just in syria, where he met one of them on the front line. Reporter escorted by a pickup truck mounted with a machine gun, we reach a front line in the fight against isis in syria. The city of hasaqa. We see remnants of battle and repeated isis suicide attacks. Like the biggest bomb i ever seen. It was just over there. Like you know about 200 meters in the air, a big fireball. And we were getting attacked. It was a suicide bomber. Reporter jared rose 25 an american from the south bronx, shows me where the isis positions are. He volunteered for this fight, joining kurdish militia, the ypg, the only forces successfully beating back isis. Theres an explosion right there. Yeah. Reporter he says hes hated terrorists ever since 9 11. Fighting for my country as well. Fighting for america. Yeah. Against isis. Yes. Before they attack us. Reporter on the other side this man amir an isis fighter who surrendered during a u. S. Air strike. Now a prisoner of the kurds. He asked that his face not be shown. Amir tells me he dropped out of college to join isis a group that cuts off peoples heads, throws people from buildings, rapes women. How can you join a group like that . They told us when we behead people we instill fear and the women we kill are adulterers, he says. Its the ideology robert came here to fight. But his unit has only old outdated weapons. 1971. Thats got 1971. He shows me a picture of his 8yearold son jonathan now living with roberts parents. They went to a yankees game before he left. Amir talks about home too. Ive been a bad son, he says. Then something unexpected happens. This isis fighter starts to cry. Well it is rare to interview an isis fighter, never mind see one break down in front of you. Isis can be beaten the kurds told me. But today two suicide bombers hit a town where we were filming just days ago. Isis will not give up easily. Lester . Keir simmons in iraq tonight for us. Thank you.
