Good day, please note that most of my communication with Hyundai has been over the phone. I sent one an email shortly after the event, and after following up on the phone, I received this following string separately. I can forward you more along the way, but Hyundai is in possession of the call recordings. I was hoping they would cover my repairs, my engine had a lifetime warranty, but during this process I learned that there was a recall for this car that I was never aware of as the new owner. I needed a software update to get any repairs covered. Please reach out to me for more info!
The affected component is the engine/rod bearing (Theta II 2.4L). My 2011 Hyundai Sonata stalled and the engine locked up twice in live traffic (March 2025 and July 2025). The vehicle is available for inspection if needed. This created a serious safety risk to me and others on the road, as the stall occurred on [XXX] at highway speeds. This failure could have been catastrophic had it happened on the DC/Baltimore Beltway or another high-traffic roadway. Hyundai’s system shows Recall 132 was marked complete at very low mileage (around 32,000 miles), but my vehicle later developed oil consumption and stalling consistent with rod bearing failure. Capitol Heights Hyundai noted a warranty pre-authorization (PA) in March 2025 and told me Hyundai needed my mailing address “for the claim,” but later said it was a typo and that no record exists. The dealership charged me for a diagnostic but did not inspect...
on [XXX] iwas driving coming back home from [XXX] by exit [XXX]. the engine turn off and didnt turn back on. i had to get a town to take me out of the highway and pay $141.00 becide that my engine seized. now i dont have a car and the car didn't gave me any notification that something it was going on with the engine. if i had any light on the car i wil take it to the mechanic, know i loss my source of income because hyundai problems with engine. and to get another engine it cost $5000. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Not sure . The car has been regulaurly maintenced and one day the emgine complagely seized up going down the road .
While driving on the highway, the motor all of a sudden lost all power and the brakes locked causing a collision. I've never had any problems until then. My car was in tip top shape with no issues until the engine / motor decided to defect. Hyundai she recall this engine issue before someone gets killed
The gear shift on its own jumps from automatic to manual mode
10/31/23 Car lost power on freeway. Dash lit up and stalled, I took picture brought to dealership. Could not find any issues or codes. 11/12/23 Driving on Pacific Coast Highway car started making knocking/ticking noise. Pull off to a side street and car hesitated and check engine light came on. Had it towed to dealership. Still waiting on assessment. Was told will take 2-3 days due to backlog. Clearly a known Engine issue dating back to recall campaign 132 Engine/inspection/replace. (I brought into dealership on 2/9/16 to perform checks on the 132 campaign - shows completed).
The contact owns a 2011 Hyundai Sonata. The contact stated while his wife was driving 10-15 MPH, the vehicle jolted, and the transmission slipped into 1st and 2nd gear. There was no warning light illuminated. The contact stated that his wife veered to the side of the road, shifted into neutral(N), and then shifted back into drive(D), and the vehicle responded as needed. The dealer was notified of the failure and advised the contact to tow the vehicle to their location because the vehicle was unsafe to drive. The vehicle was not diagnosed nor repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 82,000.
My Hyundai keeps jumping out of gear it's like the tray is sliding but it don't have one
On June 17, 2023, while during this car suddenly it started losing speed, pressing accelerator did not help. I stopped the car and restarted, it drove for another 400 yards and stopped again. I checked with my obd2 and it gave a code of misfiring third cylinder. Car had a recent replacement of engine under warranty by Parks Hyundai of Gainesville as previous engine had started smoking in 2011. My recent calls to the dealership did not result in any return call from them. Car is standing at my house for the past two weeks. I am really SCARED to drive this car. Also fed up with the dealership which does not care even to return my calls.
I was driving my vehicle and a warning light indicating hybrid system charging failure warning. The vehicle had intermittent power problems and would not move appropriately in relation to the pushing the gas pedal. It would not go then would jerk forward. I was finally able to pull over to the side of the road safely. I turned my car off and when turned back on the error message failed. This happened on two other occasions. Later there was a whining noise when shifting into second gear. I took in for service and the hyundai dealership told me the transmission needed to be replaced. My safety and others were at risk due to loss of ability to drive the vehicle appropriately due to loss of power.
I was driving my 2011 Hyundai Sonota and it felt like a truck had slammed into the back of my vehicle but it didn’t, the car was knocking and finally stopped and wouldn’t accelerate when pushing the pedal. I had to have it towed and the shop didn’t know what to do and I had it sent to Rick Case Hyundai and I explained the situation about the debris being washed out of the engine and they asked for $1700 just to look at the engine. I had a few recalls and they should have looked at the engine with no problems and no charges. They had my vehicle towed and it took me a few months to figure out what happened to my car? I have been denied EVERYTHING BY HYUNDAI CORPORATE AND TAMMY OFFERED TO LOOK AT THE ENGINE AFTER SENDING THE INFORMATION TO BBB AND SHE SAID...
My engine has failed, and my steering wheel column has locked. I had the software update on my engine with Napleton that qualified me for a lifetime engine replacement. I submitted maintenance records for my car and pictures of my valvetrain that are well maintained, and hyundai denied my engine claim for exceptional maintenance neglect on Dec8. On December 14th, after reviewing my oil changes, they still denied me for using low quality oil that's obscured. The problem I am having with my car is oil, not being able to get to the pistons inside my engine. It's not fair when the company know they engines have a manufacture defect. Then they blame the customers for lack of maintenance to have an excuse not to replace the engine. Knowing that with or without oil changes in the hyundai sonata 2011 -2012 models the engines will eventually seize anyway.I've reached out...
when driving randomly the cars engine will rev really high while pressing the gas pedal but the car doesn't move. After a little while the car eventually makes a loud clunking noise which shakes the car and typically causes the tires to spin. It seems to happen when the car is trying to decide whether to switch the gas engine or back to EV mode. This has been happening for a long time an even after the engine was replace under the recall. This is a safety issue that causes major concerns for myself an passengers. Also it happen when turning onto highways or exits which at high speeds there is a high likelihood of causing an accident. I have reported this to Hyundai several times but they cannot figure out the cause but rather keep trying different things an charging me. the car also seems to burn oil fast...
car not fully shifting into park and will not allow key to be released from ignition
drove vehicle down the street when knocking noise started, check engine light turned on, then immediately stalled. Car will not start or drive now. called hyundai recall campain and they gave me a case number of #203-102-81 with recall campaigns that could fall under 953, and or 132. There may have been an issue with the connecting rod bearings wwith a cyclic knocking noise from ther engine
The contact owns a 2011 Hyundai Sonata. The contact stated that while driving at an undisclosed speed with the vehicle in Drive Mode, the transmission erroneously shifted into the sport mode. During the failure, the gears failed to shift as needed, and the vehicle would not accelerate while depressing the accelerator pedal. After restarting the vehicle, the failure had self-corrected but would eventually the failure had recurred. The cause of the failure was not yet determined. The manufacturer and local dealer were not notified of the failure. The failure mileage was 110,000.
We broke down in the middle of the highway where there wasn’t a emergency lane available. A another vehicle struck the car in the rear .
The contact owns a 2011 Hyundai Sonata. The contact stated that while her husband was attempting to shift from drive to reverse, the gear shifter seized in the drive. The contact stated that the shifter cable had detached. The contact's husband informed the contact that a pin was missing from the shifter cable. The contact's husband opened the hood and shifted the gear manually with someone seated in the driver’s seat. The contact's husband was able to drive the vehicle to their residence. The dealer was made aware of the failure but informed the contact that the VIN was not included in a recall. The vehicle was not diagnosed nor repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 24,000.
My daughter and a passenger were driving our car at night October 3, 2021and the entire car suddenly and without notice began shaking and convulsing, became non responsive and all the electrical components and the engine went dead including inside lights, brakes, power steering and lighting system. It was nighttime and the traffic was medium but she was able to ease the vehicle onto the shoulder without incident but had a few close calls as drivers eased around her. They could have been severely injured by the traffic as it attempted to get past her on this narrow two lane road. The vehicle was towed to a mechanic who diagnosed that the engine had blown, was seized and locked up. He also mentioned that there is a recall for the 2011 Sonata and numerous problems such as this have been reported. We had no idea there was a recall on...
The contact owns a 2011 Hyundai Sonata.

TRANSMISSION OCCASIONALLY CUTS OUT WHEN CAR HAS BEEN TURNED OFF AND ON AGAIN.
MY TRANSMISSION APPEARS TO BE SLIPPING. REALLY SCARED TO DRIVE IT FAR BUT CAN'T AFFORD TO REPLACE THE TRANSMISSION.
THE CAR SPONTANEOUSLY CAUGHT ON FIRE. ORIGINATED FROM ENGINE BAY AND ENGULFED WITHIN SECONDS HAD TO JUMP OUT OF VEHICLE.
I HAVE BEEN HAVING INTERMITTENT TRANSMISSION PROBLEMS FOR A WHILE NOW. I?VE HAD THE CODES CHECKED SEVERAL TIMES AND BY SEVERAL PEOPLE, AND EACH ONE SAYS THAT ITS A CODE FOR A FAULTY AUTOMATIC TRANSMISSION TEMPERATURE SENSOR. IT CAUSES VERY HARD AND UNPREDICTABLE SHIFTING. WE?VE HAD TO STOP DRIVING IT ALL TOGETHER BECAUSE OF SAFETY CONCERNS DUE TO THE FACT THAT THE LAST TIME I DROVE IT I HAD MY 11 YEAR OLD DAUGHTER IN THE CAR WITH ME AND THE CAR WOULD NOT SHIFT INTO THE PROPER GEAR WHILE GOING THROUGH A BUSY INTERSECTION, AND WE WERE ALMOST T-BONED BY A LARGE SUV, THE IMPACT WOULD HAVE BEEN ON THE PASSENGER SIDE WHERE MY DAUGHTER WAS AND I HAVE REFUSED TO DRIVE OR ALLOW THE CAR TO BE DRIVEN SINCE. I HAVE FOUND A VERY LARGE NUMBER OF COMPLAINTS FOR THIS SAME ISSUE ON SEVERAL SITES ONLINE, MOST OF...
ENGINE SEIZED WHILE DRIVING ON MARCH 24, 2020
OUR CAR HAD A RECALL, THE RECALL WAS FIXED IN 2014, BUT IT HAS SINCE BROKEN. DURING THAT TIME WE HAVE PUT ONLY 30,000 MILES ON THE CAR. THE TRANSMISSION CABLE SNAPPED AND THEY ARE CHARGING US $1000 TO FIX SOMETHING THAT THEY SAID THEY FIXED. THIS IS A PART THAT SHOULDN'T BREAK FOR THE WHOLE LIFE OF THE CAR. OUR CAR HAD A RECALL, IT WAS REPAIRED BY HYUNDAI, AND THEY ARE REFUSING TO REPAIR THE 'REPAIRED' WORK. WE CALLED HYUNDAI CORPORATE OFFICES AND GOT THE RUN AROUND. I FEEL, IF THIS WAS A NATIONAL ISSUE, TO WHERE THEY HAD TO RECALL 850,000 CARS, THEY MUST HAVE BEEN A SERIOUS ISSUE. THEY FIXED OUR CAR 5 YEARS AGO AND SOMETHING THAT SHOULDN'T BREAK IN THE LIFE OF THE CAR BREAKS. PLEASE ADVISE US WHAT OUR NEXT STEP IS,. THANK YOU FOR YOUR TIME AND CONSIDERATION
LOUD CLUNK NOISE WILL DRIVING AND CAR WAS STUCK IN 4TH GEAR (LIMP MODE) AND CHECK ENGINE LIGHT TURNED ON. CODES P0753, P2709 AND P0758 REVEALED FAILURE OF 2 SHIFT SOLENOIDS AND LINE PRESSURE SOLENOID DUE TO TRANSMISSION WIRE HARNESS SHORTENING OUT.
MY CAR IS AT 77000 MILES IT SCARY DRIVING IT ANYMORE IT REVS UP AT A VERY LOW SPEED WON'T SHIFT AND THEN IT JUMPS SO HARD THAT IT FEELS LIKE YOUR NECK IS GOING TO BREAK I TOOK IT TO THE DEALER THEY DID A TRANSMISSION FLUSH IT GOT WORSE I TOOK IT BACK THEY DID ANOTHER TRANSMISSION FLUSH NOW IT'S TERRIBLE I TOOK IT TO A TRANSMISSION SHOP I NOW NEED A NEW TRANSMISSION $4,500 FOR A REBUILD THIS CAR IS DANGEROUS IT'S NOT ONLY HAPPENING TO ME IT'S HAPPENING TO A LOT OF OTHER PEOPLE I KNOW THAT HAVE THE SAME VEHICLE I DON'T DRIVE ON THE FREEWAYS THIS IS JUST ON CITY STREETS
I AM A SENIOR CITIZEN WHO IN 2015 PURCHASED A PRE-OWNED 2011 HYUNDAI SONATA. THE VEHICLE HAS RECEIVED 15 RECALLS IN THE TIME I'VE OWNED IT MOST OF WHICH ARE LIFE THREATENING SAFETY ISSUES , COMPLETE MOTOR LOCK UP , SUDDEN LOSS OF FUEL AND STALLING.(BRAKE STOPPER PAD MALFUNCTION 3 TIMES), SEAT BELT ANCHOR FAILURE, COMPLETE SAFETY AIR BAG FAILURE, EXHAUST SYSTEM FAILURE, HIGH PRESSURE FUEL LINE LEAKS, MY WIFE AND I LIVE ON VERY LIMITED SOCIAL SECURITY MONTHLY BENEFITS AND NOT IN A POSITION TO AFFORD A NEW CAR OR REPEATEDLY HAVE TO SPEND 100'S OF DOLLARS EVERY FEW MONTHS FOR REPAIRS DUE TO MANUFACTURE ERROR / DAMAGE IN CONSTRUCTION OF THE VEHICLE. WE HAVE BEEN NEARLY KILLED SEVERAL TIMES ON THE HIGHWAY DUE TO THE FACT THAT THE MOTOR EITHER CEASES TO GET FUEL WHILE TRAVELING ON THE FREEWAY OR ENTERING SUCH ON AN ONRAMP JUST AS A...
IN MOTION CAR SURGES AND JERKS FORWARD RANDOMLY. THERE IS A GAS SMELL WHEN DRIVING AND CAR BEGINS TO SHAKE WHEN ENGINE IS ENGAGED. BACKUP CAMERA WILL NOT ENGAGE AT RANDOM TIMES OR CAR WILL NOT TURN ON WITH PUSH TO START SYSTEM. DIAGNOSES ENGINE AND ELECTRICAL ISSUE BUT HYUNDAI WON'T INCLUDE IN THEIR RECALL CAMPAIGN.
AS STATED IN SERVICE BULLETIN 14-AT-010 THERE IS A KNOWN ISSUE WITH THE TRANSMISSION TEMPERATURE SENSOR. THIS IS COVERED ON THERE THE 2011 HYUNDAI SONATA'S 5/60,000 WARRANTY. THIS AN AN ELEMENT OF THE TRANSMISSION AND SHOULD BE COVERED UNDER THE 10/100,000 TRANSMISSION WARRANTY. BEING THAT HYUNDAI RELEASES THIS SERVICE BULLETIN, THIS SENSORS POSSIBLE FAILURE IS A KNOW FACT AND HAS BEEN EXPERIENCED BY MANY OTHERS AS MY ONLINE RESEARCH PROVED. HYUNDAI SHOULD COVER THIS AND NOT HAVE THEIR DEALERS CHARGED OVER $700 TO CORRECT THIS KNOWN FAULT IN THE HYUNDAI VEHICLE.
UNFORTUNATELY, AT 50,000 MILES MY CAR BEGAN HAVING MAJOR ISSUES. IT HAS BEEN LESS THAN A YEAR, SINCE I BOUGHT MY USED CAR, AND IT IS HAVING MAJOR MECHANICAL ISSUES. EVERY TIME I GO FROM PARKING TO DRIVE, OR DRIVE TO REVERSE, MY CAR JUMPS. WHILE ON THE HIGHWAY IT JUMPED IN MOTION. AFTER THAT INCIDENT I WAS AFRAID TO DRIVE MY CAR AGAIN. MY MECHANIC TOLD ME IT WAS THE TRANSMISSION. A NEW TRANSMISSION COSTS OVER $3,000 DOLLARS! I AM A STUDENT AND DO NOT HAVE THAT MONEY, NOR WILL I HAVE IT ANYTIME SOON. THE DEALERSHIP THAT SOLD ME THE CAR, GETTEL HYUNDAI OF CHARLOTTE COUNTY FLORIDA, NEVER ADVISED ME THAT HYUNDAI'S HAVE BEEN KNOW TO HAVE TRANSMISSION FAILURES. I INVESTED MONEY INTO A CAR THAT I CANNOT DRIVE BECAUSE IT WAS FAULTY WHEN SOLD TO ME.
WHEN CHANGING GEARS FROM PARK INTO REVERSE, THE GEAR INDICATOR SYMBOL ON THE DASH DISAPPEARED AND THE CAR STOPPED MOVING AND APPEARED TO SLIP INTO A NEUTRAL OR A NON-GEAR. AFTER PUTTING THE CAR INTO PARK, SHUTTING THE CAR OFF, AND RESTARTING THE CAR SEEMED TO HELP HOWEVER WHEN PUTTING THE CAR INTO DRIVE THE CAR JUMPED FORWARD.
WHEN ACCELERATING THE CAR JERKS AND THEN RUNS SMOOTHLY ON THE HIGHWAY, THE CAR JERKS EVERYTIME STOPPING AT THE STOP LIGHT AND MOVING FROM A STOP LIGHT AND ALSO JERKS WHEN REVERSING. THE ENGINE LIGHT CAME ON, SO I TOOK IT TO HYUNDAI DEALERSHIP. AFTER SERVICING THE CAR AND WYNN FUEL INJECTION AND THROTTLE BODY SERVICES WHICH ALREADY COST ME MORE THAN $800.00, THE TOOK THE CAR FOR ROAD TEST AND IT WAS STILL JERKING, THEY TOLD ME THAT THE TRANSMISSION BAD AND IT NEEDS TO BE REPLACED.
TAKATA RECALL, MY VEHICLE WAS IN MOTION WHEN MY AIRBAG WARNING LIGHT CAME ON 3 WEEK AGO WHILE DRIVING ON CITY STREET AND HAVE NOT COME OFF SINCE THEN. I HAVE ALSO LOOKED AT THE CAR HISTORY AND HAVE NOTICED 14 RECALLS ON THIS VEHICLE INCLUDING THE AIRBAGS. WHILE IN MOTION, MY DOORS UNLOCK BY THEMSELVES. LASTLY, THE TRANSMISSION SHIFT GEAR SOMETIMES DISAPPEAR FROM THE DASHBOARD AS WELL AS THE SHIFT GEAR WHICH IN MOST CASE THE CAR WOULDNT START OR JERKS WHEN IT DISAPPEAR WHILE IN MOTION
THE CAR SLIPS OUT OF GEAR WITH CHANGING THE SHIFTER FROM PARK TO REVERSE. THE SELECTOR WILL BE IN REVERSE AND AS THE CAR IS MOVING IT SLIPS OUT AND GOES NEUTRAL
THE ENGINE APPEARS NOT TO PERFORMING CORRECTLY. AND THE BRAKES ARE MAKING A LOUD SOUND. AND THE STEERING WHEEL IS STICKING WHILE DRIVING.
SHIFTING OF GEARS STARTED SLIPPING AROUND 100K MILES
TL* THE CONTACT OWNS A 2011 HYUNDAI SONATA. THE CONTACT HEARD AN ABNORMAL NOISE PROGRESSING FROM THE STEERING WHEEL WHEN IT WAS TURNED IN EITHER DIRECTION. IN ADDITION, ALL FOUR TIRES WERE PREMATURELY WORN TO THE POINT THAT THEY MAY NEED TO BE REPLACED. THE VEHICLE WAS INCLUDED IN NHTSA CAMPAIGN NUMBERS: 14V434000 (POWER TRAIN), 15V568000 (ENGINE), 15V759000 (SERVICE BRAKES, HYDRAULIC), 17V152000 (SEAT BELTS), AND 18V137000 (SEAT BELTS, AIR BAGS). THE CONTACT DID NOT RECEIVE ANY RECALL NOTIFICATIONS. THE VEHICLE WAS TAKEN TO PALM SPRINGS HYUNDAI (3919 E PALM CANYON DR, SUITE A, 1-(760) 202-8888) WHERE IT CURRENTLY REMAINED FOR OVER THREE WEEKS. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 23,800.
MY CAR WILL STALL IN THE MIDDLE OF DRIVING. IT HAPPENS MORE FREQUENTLY NOW AND NORMALLY HAPPENS RIGHT AFTER A LEFT OR RIGHT TURN.
IN RANDOM INSTANCES, WHILE PARKING THE VEHICLE, THE CAR WILL SHIFT TO PARK AND COMPLETELY PARK. WHEN THE CAR IS STATIONARY AND TURNED OFF, A BEEPING ALERTS BEGINS AND THE DASHBOARD SCREEN WILL PROMPT 'SHIFT TO PARK'. THE CAR WILL NOT COMPLETELY TURN OFF , LEAVING THE BATTERY RUNNING.
RECONNECTING THE BATTERY AFTER SERVICING THE CAR THE VEHICLE GETS A CHECK ENGINE LIGHT P0106 CODE (P0106 MANIFOLD ABSOLUTE PRESSURE/BAROMETRIC PRESSURE CIRCUIT RANGE/PERFORMANCE). THE ENGINE RUNS NORMAL. DRIVING THE VEHICLE AT HIGHWAY SPEEDS ON CRUISE CONTROL AT INTERMITTENT TIMES I EXPERIENCE A CRUISE CONTROL DISCONNECT AND TOTAL LOSS OF THROTTLE WHILE ENGINE IS STILL RUNNING. I HAVE TO COAST THE VEHICLE OVER TO THE SIDE OF THE ROAD AND TURN THE VEHICLE OFF AND RESTART TO GET THROTTLE CONTROL BACK THROUGH THE PEDAL. WHEN THAT HAPPENS THE VEHICLE ALSO GETS A P2110 (THROTTLE ACTUATOR CONTROL SYSTEM - FORCED LIMITED RPM LIMP HOME MODE) AND P0605 CODE (P0605 = INTERNAL CONTROL MODULE READ MEMORY (ROM) ERROR). I HAVE REPORTED THIS TO HYUNDAI. THEY RECOMMENDED I TAKE IT IN FOR SERVICE. I REPORTED IT TO THE DEALER. THEY COULD NOT DUPLICATE OR SEE HISTORY IN THE COMPUTER. THIS HAS HAPPENED SEVERAL TIMES...
VEHICLE WILL WHEN GEAR SELECTOR PUT INTO DRIVE OR REVERSE WILL JERK VIOLENTLY. THEN CAR WHEN DRIVING DOWN THE ROAD WILL DRIVE IN & OUT LOSING POWER OR TRANSMISSION SLIPPING BETWEEN GEARS?
MY CAR HAS HAD NUMEROUS RECALLS. MOST RECENTLY IT WAS MY STEERING WHEEL THAT WAS CLICKING AND FELT UNSTABLE... SO I TOOK IT INTO THE DEALERSHIP. THAT IS HOW I FOUND OUT IT WAS AN ISSUE WITH ENOUGH CARS IN THIS YR/MODEL THAT THE WARRANTY WAS EXTENDED. I ALSO WAS GETTING JOLTED WHEN I SHIFTED GEARS. EVEN IF I WAS GOING FROM PARK TO DRIVE, I COULD BE SPONTANEOUSLY JARRED VERY VIOLENTLY. I HAD THAT REPAIRED AT A OUT OF POCKET EXPENSE AT THE DEALERSHIP. TODAY I SAW EVIDENCE ONLINE THAT IT MAY HAVE BEEN A RECALL AND SHOULD HAVE BEEN REPAIRED FOR NO FEE. ANOTHER RECALL NOTICE I RECEIVED 2 DAYS AGO, SO I CALLED THE DEALERSHIP WHO SAID THEY SEE NO NECESSARY RECALLS FOR MY VEHICLE. YET, ONLINE IT SHOWS 1 RECALL ON MY CAR VIN# THAT IS OUTSTANDING BUT HAD "NO REMEDY YET" IT IS A VERY...
DRIVING CAR AND LOST ALL POWER DIAGNOSIS SHOWED NOTHING BY MY MECHANIC AFTER HYUNDAI TOLD ME CAR VIN NOT ON RECALL DURING ON VACATION ENGINE DIED HAD TO HAVE IT TOWED BACK TO MY FROM MARYLAND WAS GARAGE SAID ENGINE BEARING BROKE WILL COST ME 7000 TO MY MECHANIC
TRANSMISSION IS NOT GOING INTO GEAR, THE SHIFT GEAR IS SLIPPING AND THE WHAT THE DISPLAY SHOWS AS THE GEAR IS NOT THE ACTUAL GEAR THE CAR IS IN OR THE GEAR DISPLAY IS BLANK AND THE CAR DOES NOT GO INTO GEAR.
