Hyundai Motor America (Hyundai) is recalling certain 2017-2018 Sonata, 2016-2018 Sonata Hybrid, 2018-2020 Accent, and 2016-2017 Azera vehicles. The trunk latch may become damaged, preventing the opening of the trunk from the inside. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 401, "Internal Trunk Release."
A person inside the trunk compartment may become trapped, increasing their risk of injury.
Dealers will replace the trunk latch base, free of charge. Owner notification letters were mailed December 4, 2021. Owners may contact Hyundai customer service at 1-855-371-9460. Hyundai's number for this recall is 208.

6/5/21 2018 Hyundai Sonata - less than 20K miles Turning left into parking lot at very low speed Car completely lost all power and brakes - all dashboard lights etc went out No warning of any kind - nothing evenly remotely like this has happened before Was able to glide into parking spot and stop but only with extreme pressure on brake Key was still in on position - put car in park, set parking brake, turned key to off Car started again and was able to drive about 1/4 mile back home Immediately called dealer from whom we purchased and had car towed No diagnosis as of yet

THE OIL CONSUMPTION IS OUT OF CONTROL FOR THEIR VEHICLES I'VE HAD MORE OIL CHANGES THAT I'VE EVER DONE ON A VEHICLE I'VE DONE OIL CONSTRUCTION TESTS AND THEY ALWAYS SAY IT'S JUST AT THE 1 QUART THAT THEY ALLOW WHO'S IS BULL I'VE CHECKED MY OIL COLD AND IT'S HARDLY ON THE STICK AND THE OIL LIGHT HAS COME ON NUMEROUS TIMES I'M NO GENUS BUT I DO KNOW IT'S MORE THAN A QUART LOW WHEN YOUR OIL LIGHT COMES ON. AT 1,100 MILES IT WAS 2.5 QUARTS LOW AND I WAS FORCED TO DO ANOTHER OIL CHANGE WHEN I ONLY HAD 1,100 MILES ON THIS ONE. THE FIRST PIC I'VE ATTACHED IS COLD OIL LEVEL AT 1,100 MILES AFTER OIL CHANGE. THE CAR ONLY HAS 53K ON IT AND I WANT TO KNOW HOW MANY TIMES DO WE HAVE TO DO OIL CONSUMPTION TESTS TO GET IT FIXED UNDER THE LIFETIME ENGINE REPLACEMENT AND FORGET ABOUT THE ROADSIDE ASSISTANCE FROM HYUNDAI THEY TOW 20 MILES THAT'S IT AND THE REST IS ON YOU HOW IS THAT FAIR WHEN IT'S NOT YOUR PROBLEM TO BEGIN WITH.

I WAS DRIVING BEGAN MY SONATA IN MODERATE TO HEAVY TRAFFIC.WITHOUT WARNING THE VEHICLE BEGAN LURCHING. I WAS UNABLE TO CONTROL IT. THE HYUNDAI HAD A MIND OF ITS OWN. I GOT THE "CHECK ENGINE" LIGHT ON & SOME MESSAGE ON THE SCREEN THAT I COULD NOT READ BECAUSE I WAS DRIVING. I PULLED OFF THE ROAD & HAD THE CAR TOWED TO A HYUNDAI DEALER. UPON RETURN OF THE CAR, THE DEALER EXPLAINED THAT HYUNDAI TOOK CONTROL OF THE CAR AS A "SAFETY PRECAUTION" FOR THE ENGINE. THIS IS AN UNSAFE SAFETY PRECAUTION. THEY NOT I CONTROLLED THE CAR.
Engine, Jan 13, 2021
WHILE DRIVING CAR ON AN INTERSTATE HIGHWAY ENGINE POWER SUDDENLY DECLINED AND VEHICLE HAD NO PICKUP. I WAS UNABLE TO KEEP UP WITH THE HIGHWAY TRAFFIC, I HAD TO TOW THE CAR TO THE DEALERSHIP FOR REPAIRS. I WAS INFORMED BY THE HYUNDAI SERVICE DEPARTMENT THAT MY CAR REQUIRED A COMPUTER SOFTWARE UPGRADE TO CORRECT THE CONDITION. APPARENTLY THEY ARE AWARE OF THIS PROBLEM BUT THERE ARE NO RECALLS CONCERNING THIS PROBLEM.

I WAS DRIVING IN ANOTHER CITY AND MY CAR WENT INTO LIMP MODE. I HAD IT TOWED TO NEARBY DEALER AND THEY SAID I WAS LOW IN OIL, AFTER HAVING IT CHANGED AN MONTH BEFORE. THEY DID OIL CONSUMPTION TEST AND FOUND IT TO BE 1 QUART PER 1000 MILES AND LEFT THERE AND 2 MONTHS LATER HAD ANOTHER CONSUMPTION TEST DONE AFTER SEEING MY CAR WAS ONE IN THE CLASS ACTION ON ENGINE AND BEARINGS. THEY FOUND THIS ONE TO BE 1.1 QTS PER 1000 MILES. DEALER SAID NO WAY WILL THEY SEND INFO TO GET A NEW ENGINE UNDER WARRANTY. A QT A 1000 MILES SEEMS VERY EXCESSIVE. DEALER SAID THAT YOU NEED TO BE AT 1.5 QT PER 1000 WHICH WOULD BE ALMOST NO OIL WHEN I GO HAVE AN OIL CHANGE. THE VEHICLE IS ONLY 3 YEARS OLD AND 100000 MILES. THIS SEEMS LIKE TOO MUCH OIL TO BE BURNT. AND THEY KNOW THEY HAVE ENGINE ISSUES AND WILL NOT RECTIFY

IN FEB 2020 MY SONATA WENT INTO SAFE MODE AFTER EXITING HIGHWAY AND DEALER ENDED UP REPLACING "KNOCK SENSOR". IN DECEMBER 2020 MY ENGINE "STUTTERED" THROWING ME FORWARD AS IF I HAD HIT BRAKES HARD. NO WARNING LIGHTS OR MESSAGES OCCURRED AND AFTER A FEW SECONDS CAR ACTED NORMALLY MOSTLY. A FEW DAYS LATER AFTER EXITING HIGHWAY AGAIN THE ENGINE WARNING LIGHT (ORANGE) CAME ON ALONG WITH ERROR MESSAGE "POSSIBLE CONDITION WITH ENGINE CONTROL SYSTEM" HAS BEEN DETECTED. CAR DID NOT GO INTO "SAFE MODE" AND SEEMED TO BE OPERATING NORMALLY. I CONTACTED DEALER WHO ASSURED ME SAFE TO DRIVE OVER HUNDRED MILES BACK TO DEALERSHIP IN THIS CONDITION TO CHECK. I DROVE BACK FROM EAST COAST FL TO WEST COAST FL TO TURN CAR IN. I BELIEVE ENGINE ISSUE EXPERIENCED IS RELATED TO THE THETA ENGINE ISSUE AND REPAIR WOULD BE COVERED UNDER SETTLEMENT. DEALERSHIP DISAGREES AND HAS INDICATED ISSUE IS WITH FUEL PUMPS (BOTH ARE BEING REPLACED) AND CHARGING ME $2300.
Engine, Sep 24, 2020
I TURNED ON MY CAR AND THE MALFUNCTION INDICATOR LIGHT TURNED ON MY DASH BOARD. I PUT THE CAR IN REVERSE AND IGNORED IT. KEPT DRIVING. THE CAR TURNED OFF COMPLETELY WHEN I WAS TURNINGIN IN A BUSY INTERSECTION. I TURNED IT ON AGAIN AND IT DIDN'T WANT TO EXCELERATE.

EVERYTIME I ACCELERATE MY SUV MAKES A VERY LOUD GRINDING / ? NOISES AND SOMETIMES WHEN I SLOW FROM ACCELERATING. TALKED WITH HYUNDAI MECHANIC THAT SAID THEIR MAY BE A ENGINE PROBLEM. ONLY HAD IT 1 MONTH. I AM AFRAID THAT IT WILL BECOME VERY DANGEROUS TO DRIVE IT.

I WAS DRIVING MY CAR AT ABOUT 45MPH ON MY WAY TO WORK ON A HIGHWAY ROAD AND OUT OF NO WHERE IT JERKED AND THE CHECK ENGINE LIGHT STARTED FLASHING. CAR WOULD NOT ACCELERATE ABOVE 2,000 RPMS. WHEN THE CAR JERKED, IT WAS SO SUDDEN IT INJURED MY LOWER BACK. MY BACK HAS BEEN VERY SORE SINCE THIS INCIDENT. I THEN TOOK TO DEALER AND THEY SAID IT WAS A KNOWN ISSUE AND HYUNDAI HAD NOT RECALLED MY SPECIFIC CAR. DEALER WAS ABLE TO REPLICATE THE ISSUE. THE CLEARED THE CHECK ENGINE LIGHT AND SENT ME ON MY WAY. ONE MILE DOWN THE ROAD EXACT SAME THING HAPPENED. CAR IS CURRENTLY AT THEIR SHOP WITH NO ETA OF REPAIR.

MY 2018 SONATA WILL NOT START WHEN TEMP DROPS BELOW 20 DEG F. IT HAS HAPPENED 3 TIMES THIS WINTER AND WHEN IT WARMS BACK UP TO 40 TO 50 DEGREE IT WILL START. WHEN I TURN THE KEY ON ALL THE LIGHTS ON THE DASH LIGHT UP LIKE NORMAL. I CAN MOVE HEAR SELECTOR AND TURN WHEEL. BUT THE STARTER WILL NOT ENGAGE NOTHING IS HEARD NOT A CLICK OR A SHIRT. IS THIS COMMON PROBLEM?

ON FIVE SEPARATE OCCASIONS WHILE DRIVING ON THE HIGHWAY THE VEHICLE WILL LOOSE POWER AND ABILITY ACCELERATE WITH A FLASHING ENGINE LIGHT. THESE INCIDENTS HAVE ALMOST CAUSED ME TO BE REAR ENDED THREE TIMES BECAUSE YOU ARE NOT ABLE TO ACCELERATE ABOVE 60MPH IN RUSH HOUR TRAFFIC ON A BUSY INTERSTATE AND THE ABILITY JUST STOPS QUICKLY WITH NO WARNING. THE VEHICLE ALSO HAS BEEN HAVING THE RPMS DROP TO 0 AND SHOOT BACK UP WHILE BRAKING, AND WHILE DRIVING IT IS TOUGH TO ACCELERATE AND THEN YOU WILL FEEL A NOTICEABLE 'KICK' AND THE RPMS WILL SHOOT UP DRASTICALLY BEFORE IT WILL ACCELERATE. I HAVE HAD 2 SOFTWARE UPDATES DONE, A NEW WIRE HARNESS, KNOCK SENSOR CLEANING AND A KNOCK SENSOR REPLACEMENT. THE ENGINE CODE IS ALWAYS THE SAME 1326.
Vehicle speed control, Engine, Nov 9, 2019
ON 2 DIFFERENT DAYS THE CAR KILLED ON THE HIGHWAY. BOTH TIMES THE HYUNDAI SERVICE DEPT. LOOKED AT IT. THE FIRST TIME, THEY SAID THE SOFTWARE UPDATE THAT WAS WORKED ON A FEW MONTHS PREVIOUS, HAD A GLITCH IN IT. THE SECOND TIME THEY SAID THEY DIDN'T KNOW WHY IT HAPPENED. WHILE DRIVING THE RPMS WILL RACE UP BUT THE CAR DOESN'T MOVE MUCH. THEY SAID IT DIDN'T DO THAT WHEN THEY DROVE IT. ALSO SINCE THE FIRST SOFTWARE UPDATE WAS DONE , IF I DRIVE 80MPH (ON THE INTERSTATE HWY.) THE SEATS SHAKE.

JUNE 2019, AT ABOUT 11,500 MILES TOOK CAR IN FOR AN OIL CHANGE AND WAS TOLD DUE TO A RECALL, A SOFTWARE UPDATE NEEDED TO BE DONE. AT ABOUT 13,500 MILES, ENGINE LIGHT CAME IN, CAR WAS JERKING IN MOTION ON HIGHWAY AND LOST POWER. CAR WOULD NOT ACCELERATE LAST 62 MPH. CAR WAS SERVICED AND BLOCK SENSOR WIRE HARNESS WAS REPLACED. CAR WAS RETURNED AND AGAIN WHILE IN HIGHWAY ENGINE LIGHT CAME ON, LOST POWER, CAR WAS JERKING WHILE CHILD WAS IN THE CAR AND WHILE CAR WAS IN MOTION. CAR WAS SERVICED AND BLOCK SENSOR WAS REPLACED. AT ABOUT 18K MILES, ENGINE LIGHT CAME ON WHILE ON HIGHWAY AND AGAIN WITH CHILD IN THE CAR AND CAR LOST POWER AND ALSO WAS JERKING WHILE IN MOTION. CAR WAS SERVICED AND ENGINE REPLACED. 3000 MILES LATER, AGAIN WHILE IN THE HIGHWAY, ENGINE LIGHT CAME ON, CAR LOST POWER AND WAS JERKING AND WOULD NOT ACCELERATE. CAR WAS SERVICED AND THE FOLLOWING DAY, WHILE ON THE EXPRESSWAY IN CHICAGO, THE ENGINE LIGHT CAME ON AND THE CAR LOST POWER AND WAS JERKING HARD WHILE IN MOTION. CAR WAS TOWED TO DEALERSHIP IN ROCKFORD IL. AFTER THE 4TH ATTEMPT TO REPAIR, LEMON LAW CLAIM WAS FILED WITH HYUNDAI MOTOR AMERICA WHICH THEY DENIED DUE TO MILEAGE. THIS CAR IS UNSAFE TO DRIVE. WHEN IT LOSES POWER THERE IS NO WARNING, NO BRAKE LIGHTS COME ON TO NOTIFY CARS BEHIND, AND WHILE IN THE BUSY EXPRESSWAY IN CHICAGO WAS VERY DANGEROUS. ALSO DANGEROUS TO HAVE CHILDREN IN THIS VEHICLE. HYUNDAI MOTOR AMERICA REFUSES TO DO ANYTHING BUT REPAIRS AND IS IGNORING THE DANGEROUSNESS THIS PROBLEM. THIS OCCURRED ALL 5 TIMES WHILE THE CAR WAS IN MOTION. THE CODE THAT READS FOR THIS IS 1326 PER THE SERVICE RECORDS.

ON FRIDAY, MAY 31, 2019, WHILE DRIVING HOME FROM WORK, I NOTICED MY VEHICLE BEGAN TO SHAKE WHILE DRIVING. (CAR HAS 14K MILES) I CALLED GOSSETT HYUNDAI AT COVINGTON PIKE AND WAS TOLD IT WAS PROBABLY A ROTOR OR A SPARK PLUG AND TO BRING IT IN SATURDAY MORNING. SATURDAY MORNING, WHILE DRIVING TO THE DEALERSHIP, THE BLUELINK LIT UP SAYING MY CAR NEEDED TO BE SERVICED. I DROVE THE VEHICLE TO GOSSETT HYUNDAI AT MT. MORIAH. AFTER GOING BACK AND FORTH (IN FRONT OF THE TECH) THEY AGREED TO RUN A DIAGNOSTIC (BECAUSE I TOLD THEM I WAS WORRIED ABOUT DRIVING MY CAR TO THE COVINGTON PIKE LOCATION), AND THE TECH INFORMED ME THAT HE WAS A TECH AND HE COULD RUN THE DIAGNOSTIC. AFTER RUNNING THE DIAGNOSTIC, I WAS TOLD THAT ONE OF MY CYLINDERS WAS NOT FIRING. AFTER SOME PERIOD OF TIME, THEY LOCATED AN IGNITION COIL IN THE PARTS ROOM AND REPLACED IT. THE CAR STILL WAS NOT RUNNING CORRECTLY, I WAS INFORMED THAT THE CAR NEEDED A SPARK PLUG BUT THEY WOULDN'T HAVE ONE UNTIL TUESDAY, JUNE 4, 2019. AFTER THE DEALERSHIP RECEIVED THE SPARK PLUG AND INSTALLED IT (I GUESS?), THE CAR WAS STILL SHAKING AND NOT RUNNING CORRECTLY. SOMETIME JUNE 5 OR 6TH, THEY CALLED HYUNDAI MANUFACTURING AND HAVE BEEN RECEIVING INSTRUCTION FROM THE MANUFACTURER DIRECTLY TO RUN LEAK TESTS. I WAS INFORMED THAT THEY ALSO USED A CAMERA TO LOOK DOWN IN THE CYLINDER AND THAT IT HAS 'SCARRING' WHICH COULD BE FROM FLUID GETTING INSIDE? I HAVE ALSO BEEN TOLD THAT IT IS PROBABLE THAT MY CAR WILL NEED A COMPLETE NEW ENGINE. IT HAS BEEN 2 WEEKS AND THE DEALERSHIP IS WORKING CLOSELY WITH THE MANUFACTURER TO SEE WHAT NEEDS TO BE DONE.
Engine, May 25, 2019
DRIVING AND ENGINE LIGHT STARTED FLASHING AND I COULD NOT KEEP UP WITH THE SPEED LIMIT AS THE CAR WOULD ONLY GO ABOUT 20 MPH. THE CAR SAYS "POSSIBLE CONDITION WITH YOUR ENGINE CONTROL SYSTEM HAS BEEN DETECTED" CAR WAS IN MOTION ON CITY STREET.

I PURCHASED THE 2018 HYUNDAI SONATA 2.0T ON 8/27/18. AFTER WE WERE ABLE TO EXPERIENCE DIFFERENT DRIVING CONDITIONS AND SITUATIONS, MY HUSBAND AND I NOTICED THAT (1) AT NIGHT, WHILE DRIVING ON THE HIGHWAY, THE WINDSHIELD APPEARED VERY DARK AS IF IT WAS HEAVILY TINTED,AND MAKING IT DIFFICULT TO SEE THE ROAD. (2) WHEN DRIVING ON HIGHWAY OR ROAD, WITH NORMAL BEAM HEADLIGHTS, WE NOTICED THAT THE LINE OF DEMARCATION FROM HEADLIGHT TO DARK ROAD WAS VERY CLOSE TO THE FRONT OF THE CAR. THE REASON GIVEN BY THE MAINTENANCE DEPT WAS THAT THIS WAS SO CARS IN FRONT WOULDN'T BE BLINDED BY THE HEADLIGHT. TO US, IT SEEMED THAT THE HEADLIGHTS WERE AIMED TOO LOW. I SHOULD BE ABLE TO SEE MORE THAN 20 FEET IN FRONT OF MY CAR. WE WERE TOLD THAT NOTHING COULD BE DONE. ALSO, WHEN MAKING A TURN, THE AREA OPPOSITE THE DIRECTION OF THE TURN IS COMPLETELY DARK BECAUSE OF THE WAY THE HEADLIGHTS WORK ON A TURN. THIS IS EXTREMELY DANGEROUS-SHOULD SOMEONE DECIDE TO WALK THERE OR IF THERE IS AN ANIMAL, I WILL NOT BE ABLE TO SEE ANYTHING. AGAIN I WAS TOLD THERE WAS NOTHING THEY COULD DO. (3) MY HUSBAND PUT RAIN-X ON ALL THE WINDOWS OF THE CAR. IT WORKED ON EVERY WINDOW EXCEPT THE WINDSHIELD. WE THOUGHT THERE WAS SOME SORT OF COATING PLACED BY THE MANUFACTURER. I WAS TOLD NO THERE WAS NOT. THEY COULD NOT UNDERSTAND WHY THE RAIN-X DIDN'T TAKE. THEY TOLD ME THAT THEY SPENT QUITE A BIT OF TIME "SCRAPING THE WINDSHIELD", BUT NOTHING CAME OFF. WE STILL DO NOT KNOW WHY IT SHOULD DO THAT. (4) I NOTICED. WHETHER I WAS DRIVING IN SMART OR SPORT MODE, THEIR IS AN ANNOYING HESITATION WHEN I STEP ON THE GAS. WHEN THE STOPLIGHT TURNS GREEN, IT TAKES SEVERAL SECONDS BEFORE THE CAR IS ABLE TO MOVE AT NORMAL SPEED. WE WERE TOLD THAT THEY RECEIVED LOTS OF COMPLAINTS ABOUT THAT, BUT NO OFFER FOR A FIX.

TL* THE CONTACT OWNS A 2018 HYUNDAI SONATA. THE CONTACT STATED THAT THE VEHICLE WAS TAKEN TO HYUNDAI OF KIRKLAND DEALER (11706 124TH AVE NE, KIRKLAND, WA 98034, (425) 821-6611) WHERE A SOFTWARE UPDATE WAS COMPLETED. THE CONTACT STATED THAT WHEN LEAVING THE DEALER WHILE DRIVING AT 40 MPH, THE VEHICLE STALLED AS THE CHECK ENGINE AND THE ENGINE CONTROL SYSTEM FAILURE DETECTED WARNING LIGHTS ILLUMINATED. THE CONTACT STATED THAT THE VEHICLE SPEED AUTOMATICALLY DECREASED TO 10 MPH. THE CONTACT STATED THEY SLOWLY DROVE BACK TO THE DEALER, WHERE IT WAS DETERMINED THAT A NEW ENGINE WAS NEEDED. HOWEVER, A WEEK LATER HE WAS INFORMED BY THE DEALER THAT THE WIRE HARNESS HAD FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE CONTACT HAD SPOKEN TO THE MANUFACTURER VIA EMAIL AND WAS PROVIDED A CASE NUMBER: 15658545. THE APPROXIMATE FAILURE MILEAGE WAS 3,713.

I WAS EXITING THE FREEWAY AND LOST POWER, COULD NOT ACCELERATE, BLINKING ENGINE CAME ON AND ON MY SCREEN IT SAID "A POSSIBLE CONDITION WITH YOU ENGINE CONTROL SYSTEM HAS BEEN DETECTED. A FULL SYSTEM CHECK RECOMMENDED TO BE DONE WHEN CONVENIENT. PLEASE CONTACT YOU LOCAL DEALERSHIP FOR AN APPOINTMENT" I WAS ABLE TO GET TO AN AREA AND HAVE IT TOWED. THIS COULD OF BEEN VERY SCARY AND DANGEROUS IF I HAD STILL BEEN ON THE FREEWAY DOING 70! I COULD NOT HAVE DRIVEN IT, IT WAS MISSING AND WOULDN'T GET ABOVE 20-30 MPH. I HAD THE KNOCK SENSOR SOFTWARE UPDATE DONE AT THE DEALER THE WEEK PRIOR TO THIS HAPPENING. THE DEALER IS SAYING THE WIRING HARNESS NEEDS REPLACED AND WILL NOT BE AVAILABLE UNTIL THE END OF THE MONTH! MANY ON HERE HAVE WAITED MONTHS I HOPE THAT IS NOT THE CASE. I'VE READ NUMEROUS COMPLAINTS ON HERE AND OTHER SITES THAT THIS IS HAPPENING AFTER THE UPDATE. MY CAR SEEMED FINE BEFORE THEY DID THE UPDATE. SOME PEOPLE NEED NEW ENGINES! HOW DO I KNOW THAT MY ENGINE DOESN'T HAVE DAMAGE, I ASSUME THAT HYUNDAI KNOWS SOMETHING SINCE WITH THE SENSOR UPDATE THEY EXTENDED MY 100K WARRANTY TO 120K. IT SAID THE SENSOR IS TO HELP CATCH POSSIBLE ROD BEARING WEAR AND EXTENDS WARRANTY MUST MEAN THEY EXPECT ENGINES TO HAVE PROBLEMS! WHAT IS GOING ON HERE AND WHY ISN'T THERE ANY OFFICIAL RECALL? MY CAR ONLY HAS 20K I DON'T EXPECT THIS KIND OF PROBLEM. I LEASED CARS FOR MANY YEARS BUT SINCE I'M CLOSE TO RETIRING I BOUGHT THIS WISH I WAS STILL LEASING SO I COULD GET OUT FROM UNDER THIS IN 2 YEARS!

MY DAUGHTER WAS DRIVING ON THE HIGHWAY WHEN THE CAR STARTED TO BUCK AND WOULDN'T ACCELERATE. THE CHECK ENGINE LIGHT CAME ON AND SHE PULLED OFF THE HIGHWAY. SHE CALLED HYUNDAI AND THEY TOLD HER NOT TO DRIVE THE CAR AND TO HAVE IT TOWED TO A DEALERSHIP. WE WERE THEN TOLD BY HYUNDAI THAT THIS IS A KNOWN PROBLEM. THEY INSTALLED A KNOCK SENSOR WIRING HARNESS AND SAID THEY HOPE THAT DOES THE TRICK BUT IT COULD NEED A WHOLE NEW ENGINE. EXPECTED REPAIR TIME IS 6 WEEKS SINCE PARTS ARE ON BACKORDER. WE HAVE SINCE SPOKEN TO SEVERAL DEALERSHIPS AS WELL AS CONSUMERS AND THERE ARE SO MANY COMPLAINTS THAT SOME PEOPLE HAVE BEEN WITHOUT THEIR CARS FOR MONTHS.
