2017 HYUNDAI SONATA Power Train Problems

Airbags did not deploy no indicator light came on before nor after I was struck from my driver side front area and yes it is available for inspection upon request. My safety along with my sisters safety was put at risk due to the negligence and cheapness of the dealership I purchased the car from also from there misleading information and improper inspection before selling me the car Car has not been reproduced or confirmed The car was inspected by a third party appraisal company for damages amounts There were no lights on at all before the accident and I am pretty certain that the dealership cleaared the codes before selling me the car

e vehicle is burning approximately 2 quarts of oil every month with no external leaks. This indicates severe internal oil consumption, which is a known defect in Hyundai’s Theta II 2.4 GDI engines. I discovered oil inside the VVT solenoid electrical connector and on other wiring, which shows oil is traveling through the engine harness. This causes hesitation, rough running, and the risk of sudden engine power loss. The vehicle feels unsafe to drive because the oil level drops quickly, and the engine could seize or stall while driving. Hyundai vehicles of this generation have a history of excessive oil consumption, piston ring failures, and engine fires, and I believe my vehicle is experiencing the same defect. This is a serious safety concern.

What component or system failed or malfunctioned, and is it available for inspection upon request? The engine in my 2017 Hyundai Sonata Sport is defective. Oil pressure failed testing, oil contamination was found on the oil pressure sensor and connector, and the vehicle has experienced excessive oil issues. The engine is still in my possession and available for inspection upon request. How was your safety or the safety of others put at risk? The vehicle has gone into limp mode on the highway, which caused a sudden loss of power and created a dangerous situation in traffic. The car also shakes, misfires, and loses power unexpectedly, which could lead to stalling or loss of control at highway speeds. I do not feel safe driving the car. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Multiple Hyundai dealerships have inspected the car. One confirmed low oil pressure and oil contamination at the sensor. Previous visits dismissed the oil warning and charged me for oil replacement instead of identifying the underlying defect. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes. The vehicle has been inspected by Hyundai dealers multiple times. I also have two inspection reports from the same dealer just two weeks apart with contradictory findings the first showing no oil issue, the second confirming oil contamination and failed oil pressure. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes. The oil warning light and check engine light have both come on. The vehicle has gone into limp mode, and symptoms have included shaking, misfiring, rough idling, and loss of power. These issues began months ago and have continued despite repeated service visits.

I am leasing a 2017 Hyundai Sonata from Car City in Michigan. In May 2025, the vehicle received a brand-new engine replacement due to previous problems. I picked the car up on [XXX], and on the same day, the vehicle began malfunctioning. It would not accelerate properly, jerked and stalled, and multiple warning lights — including the check engine light — came on immediately. This made the car unsafe to drive. I contacted the dealer, but they told me to wait until Monday to get it looked at, leaving me with a dangerous and unreliable car. The vehicle had already been in the shop for over two months for the engine issue, and I had only driven it for six months beforehand. I believe the repair or replacement engine is defective or was not properly installed. This creates a serious safety hazard. A car that stalls while driving puts everyone at risk. I am filing this complaint so this issue can be investigated and addressed if others are affected. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The engine in my 2017 Hyundai Sonata has been burning excessive amounts of engine oil over an extended period. The issue started approximately 10,000 miles ago but has worsened recently, requiring frequent oil top-offs between regular oil changes. The oil consumption is abnormal and not consistent with normal wear. This excessive oil burning poses a potential safety risk, including possible engine failure, stalling, or fire hazard due to low oil levels if not monitored carefully. The vehicle has not yet experienced a complete failure but the risk concerns me. The problem has been observed consistently during normal driving conditions. I have not yet had an official inspection or oil consumption test performed by a dealer, but I intend to request one. There have been no warning lights related to the oil burning issue, but the oil level drops rapidly and noticeably.

Constant losing oil, constant changing of spark plugs, car shaking, can't pick up speed

All documents are attached as it is many separate incidents that ended knock from motor and minutes later, a piston shooting through the engine block which is what made the car inoperable

The check engine light light is on now giving code p200a I was driving and the center console shut off and the engine died I had to pull over and start the car again it started but the check engine light light is on now for a p200a I’ve looked it up and everything I can find says there is a recall but my car isn’t in it so what can I do I don’t want to cause a fire or an accident because my car messed up o.

I have to add a quart of oil to car a day tul the motor blew

The car is burning through oil at an excecated rate. This is a well-known issue with this make and model. The dealer said they fixed the problem, and they did not. This engine needs to be replaced. It was inspected by a mechanic not affiliated with Hyundai. Hyundai has refused to replace the engine. This should be covered by the 15 year/ 150,00 engine warranty. This engine could seize up at any time. It is a hazard to be driving. The driver is an 80-year woman. She needs help.

I was driving the vehicle and it of no where the hybrid warming triangle comes up and I had to pull over. The car went in creep mode and then rpm and sped was capped.

While driving on a highway at ~60 mph, the check engine light came on (plus other indicator lights) and the car immediately dropped to ~45 mph. ~20 seconds later, while trying to pull into a school parking lot, the hybrid system fault warning came on and the car dropped to ~5-10 mph and then became extremely difficult to control. The car was towed ~80 miles to my home dealership and it was diagnosed as a partially blocked EGR tube. ~1 month later, on the next longer drive I had to make (all other drives were short distances), ~70 miles into the drive, the car started making a knocking sound and then suffered the same failure under the same kind of conditions. This was diagnosed as a failed knock sensor. One week later I tried to drive it a long distance to see if the problem would happen again (but closer to home) and while traveling on an interstate highway the same issue occurred. This time it was diagnosed as oil in the wiring assembly for the just replaced knock sensor. The dealership tried to give me the car back but I demanded that they do a long test drive. It took 4 days to get them to do what I asked and then they had it break down on them in the same way. I'm not 3+ weeks after that and still don't have the car back (now they're planning to replace the EGR assembly and intake manifold). Each breakdown has thrown the P1326 trouble code but Hyundai refuses to admit that the issue may be the engine itself (related to the recall). It took until the 3rd breakdown and a lot of demands to get a loaner vehicle. I don't know if this is the known engine issue, something else or new but don't feel that Hyundai is taking it seriously. If nothing else, the programming that was added to put the car in safe mode and prevent fires is too aggressive and in each case has made the car undrivable in less than 1 mile. I have gotten lucky in all cases that a safe place to stop was nearby but it is not safe to drive in many areas due to lack of safe pull off location

My son was driving the car, and completely out of nowhere it seized to have any compression and steering/accelerating became disabled. I have been given an estimate up to $7,000 for an engine rebuild due to this happening. I have reached out to Hyundai and they denied my claim due to car being out of warranty. This should have never happened when the car has been well maintained,even with the motor burning through oil faster than it should be, which I have always kept a close eye on. This car is defective and unsafe.

Engine oil light or any warning lights and symbols never came on after Engine had burned out all the oil. Had oil changed and new oil filter installed and in less then a week it burned out 3 quarts, again with no low oil warning at all. Motor stalled at intersection and had to cool down, oil was again added and lower Engine knocking was present. Meanwhile had a mechanic inspect it and diagnostic done and lower bearings are knocking. Vehicle has had this issue for over 4 years and never mentioned to us until now after 100,000 miles. 2019 is when this oil burning issue began. Hyundai dealer serviced this several times and never mentioned the reason for the knocking other then it was low on oil. After breaking down in a busy intersection had to be pushed off road and waited for Engine to cool down to add oil and knocking continued.

My 2017 Hyundai sonata burns oil rapidly, almost 400 miles it burns 5 quarts of oil. The engine stalls randomly and beings to mis fire. The car has stalled on me in the middle of the road with no check engine light or indicator that a problem is present. I have had to change spark plugs and coils far to offen and every time I have to pay the mechanical shop. There is a recall on the hybrids sonatas but not the gas ones. The dealer acknowledges that the car burns oil allot. Which I’ve been told it can lead to engine failure I have done everything possible. And I’ve spoke to other owners and I’m not alone. The vehicle hasn’t been inspected by others such as police. No warning lights appear

I was traveling on [XXX] Baton Rouge La. and Gonzales La. at 70 mph when I lost power to my vehicle , an alarm sounded saying it was the Hybrid control system failure, putting my safety at risk as I had to maneuver off the interstate and onto the shoulder during heavy traffic . I called State Farm insurance to get my vehicle towed to Ralph Sellers Hyundai in Gonzales La. where it is being repaired.

While driving the vehicle on the highway, the check engine light began flashing and the car immediately lost almost all power. We had enough power to pull off of the highway off-ramp where the vehicle began jolting before stalling on a side road. We started the car back up and had just enough power to drive into the hospital parking lot next to the side road, where we had it towed to the Hyundai dealer across the highway. That Hyundai dealer identified the Intake Manifold Runner as the culprit via engine fault code P200A00. This Hyundai dealer was also concerned with oil consumption as the car's oil was low even though it had been maintained according to Hyundai standards. They did an oil consumption test, but argued that it was normal, while refusing to repair or replace the Intake Manifold Runner, & only cleaned the Intake Manifold Runner, for which they charged. They gave us the car back and it continued to consume oil to the point where the dipstick was reading below the low line. The car also continued to jolt and have low power. This same Hyundai dealer told us to add oil to the engine and have it towed to them, which we did. They then claimed the car had too much oil, blamed us for it, and continued to refuse to investigate the issue any further. They gave us the car back after a lot of confrontational back and forth on their part where they agreed to change the oil and do another oil consumption test at no charge. A few weeks later, the check engine light came back on, the car lost power, and we called the same dealer back. The dealer refused to help us, so we took it to another dealer who found the same P200A00 fault code and replaced the entire Intake Manifold Runner under warranty without any questions asked, and at no charge. When we were still dealing with the first Hyundai dealer, we opened a case on them through Hyundai corporate, but corporate did nothing and did not care about the issue. Hyundai Corporate and one of their dealers ignored 21-EM-008H.

The car is consuming excessive amounts of oil. The engine has a knocking, tapping sound. Found out today the intake manifold is bad, which we all know is a very bad thing to go wrong. The engine has a very bad misfire. The car only has 53k miles. I own an 09 Sonata with 154k and I have never had a problem. This is why I continued with Hyundai. Also, the steering seems to tense up regularly. I am very worried about driving this vehicle. I have read hundreds of complaints regarding the excessive oil consumption. I feel you need to express the importance of these concerns to Hyundai

Burning over a quart of oil every 500 miles.

On 12/26/22, I was on a road trip and the car began vibrating violently on the PA turnpike. The car was losing power and would not accelerate. I was forced to stop on the highway with my kids in the car. Hyundai repaired the cylinders in the engine and then it began burning excessive oil, 1 quart ever 1000 miles. For months, I drove this car and as the oil got lower, the car hesitated while driving and ran very rough. On 7/4/23, transmission overheated and once again, car lost power on the road and left me stranded with my kids. Engine is burning excessive oil and causing other issues with car. Was not fixed when car died the first time and has now left me limping along and stranded twice. Car has been at shop since 7/5/23. Engine approved, but dealer can’t get parts. Hyundai won’t approve transmission until engine is replaced, leaving me to drive an unreliable car again when transmission and engine both have known issues. It’s unsafe to continually be stranded by a car that clearly has a bad engine. Would have been more cost effective for Hyundai to replace car at this point and still being given runaround by corporate.

My engine seized up after burning every drop of oil dry. My last oil replacement was 5,200 miles prior, and Hyundais recommended mileage before replacement is 7,500 miles. I never got a single oil annunciator light.

I was driving southbound on I429 approaching the Vineland Wintergarden (FL)exit. approximately .75 miles from exit, a bit of an uphill. I heard a ticking noise, then suddenly the car went silent. The screen lit up with every sensor flashing. It took me a few seconds to realize I was in potentially deadly trouble. The car began slowing from 70 MPH to maybe 25MPH as I crested the last hill. To add complications, that stretch is under construction and does not have any shoulder. I could see a wall of cars streaming ever closer in my rear view mirror. I believe my hazzard lights probably saved me from a crash before gliding the last 1/4 mile to the exit where I was able to finally pull over to safety.

Car completely lost all power train systems while in motion after repair at dealership for HSG. Car was able to be restarted after shifting into park after complete stop. All instructions in user manual for restarting vehicle while in motion were followed but not successful. The vehicle died again pulling into dealership and the tech began diagnosis.

Total loss of power while driving occurred on 2 separate occasions driving the Hyundai Sonata. The dashboard lit up with multiple failures with no warning, and car lost all power. Both times were in peak traffic conditions and on one of the two instances, a very dangerous mountain road with very little time to react. Towed on 2 occasions to 2 different dealers with no clear cut fix for the car. These were very scary and dangerous incidents and I am afraid to drive this car to be honest. Hyundai has not done much to contact or reassure me that they were dealing with the situation.

Driving this passed saturday and my car was jumping when i would slow it down to decrease my speed. Once my car got to 5mph it’ll jump forward then it would stop. When i went to accelerate it would pick up no speed until 40mph then the engine light came on. I went to get a diagnostic from autozone and it was my power train system having an issue. I have no clue what that was. Went to make an appointment for hyundai NO appointments for a month! What happens if the car shuts down on me? or doesn’t brake when i press on it?

Driving on highway went to pass a vehicle and merge into the next lane, when car lost speed. Pulled over and tried to restart car, car restarted only to shut right back off. Put quart of oil in and shortly after there was a clicking noise when I got up to speed, I had to put two more quarts in as well as a cleaning additive. Cannot drive over 8 mph without car making noise

The check engine light came on and wouldn't accelerate normally. The speed was delayed and cutting back and wouldn't pass 40 mph. Upon taking it to a local shop it had to be taken to the buying location by road side assistance. After the service department checked into the problem it now needs a new engine. They stated there were metal shavings in the motor. This was transferred by a known problem in the 2.4 L motor that hyundai has put in their vehicles with problematic bearings. This happened within 2 months of buying this vehicle. We Can't drive it at all now so it's still at the shop.

at 75000 miles car started to be out of oil 2000 miles after the oil change. At 83000 miles motor went. Check engine lite went on and day later started blinking and car died on the highway. Just went dead. Mechanic tells me motor is shot please help

It's knock sensor issue code was showing since 85000 mileage, dealer just got rid of the code and said can drive safely. Then again at 101000 mileage knock sensor code and Hyundai dealer said software is updated can drive safely. Also it's engine oil burning faster that we keep on topup oil all time. Then at after 108000 mileage my car started overheating, & it's engine seized. Now Hyundai don't want to fix such problems. I don't know maybe it get fixed, then catches fire on highway can cause death.

APRIL 28, 2022 THE ENGINE. IT IS REPLACED AND STILL AT ANTWERPEN HYUNDAI IN BALTIMORE MD. AT GREAT RISK BECAUSE THE CAR WOULD LOSE ALL FORWARD POWER AND REDUCE SPEED FROM60 MILE PER HOUR ON A BELTWAY WHERE THE TRAFFIC MOVES VERY FAST AND I WOULD QUICKLY GO DOWN TO 20 MILES PER HOUR. THE PROBLEM WAS DIAGNOSED BY 2 CERTIFIED MECHANICS BEFORE TAKEN TO ANTWERPEN WHERE THE 3RD DIAGNOSIS WAS PROVEN A NEED TO REPLACE THE ENGINE. I AM NOT SURE IF IT WAS INSPECTED BY THE MANUFACTURER BUT THE SERVICE DEPT. AT ANTWERPEN WERE IN TOUCH WITH THE MANUFACTURER BECAUSE THEY APPROVED REPLACING THE ENGINE. THERE WERE NO-(NONE) CHECK ENGINE LIGHTS BUT IT DID SAY CHANGE THE OIL. I DID CHANGE THE OIL EVEN THOUGH IT WAS ONLY 1200 MILES SINCE THE OIL HAD BEEN CHANGED. THE POWER FAILURE OCCURED TWO TIMES PRIOR TO THE FINAL TIME AND I TOOK IT TO JENKINS HYUNDAI IN LEESBURG FLORIDA (WHERE I BOUGHT THE CAR) AND THEY CONTINUED TO REPORT NO PROBLEMS. THE PROBLEM 1ST APPEARED WITHIN THE FIRST 30 DAYS OF THE PURCHASE ON MAY 22, 2021. UPON RECEIVING THE CAR BACK AFTER ENGINE REPLACEMENT THE CAR WAS BLOWING BLACK SMOKE (LOTS OF IT) I TOOK IT BACK TO ANTWERPEN AND THEY FOUND THE TURBO WAS COMPLETELY DESTROYED (BECAUSE THE MANUFACTURER HAD THEM -POWER CLEAN?-THE TURBO. THE MANUFACTURER AGREED TO PAY TO REPACE THE TURBO. HOWEVER UPON CLOSER INSPECTION THE CATELETIC CONVERTOR WAS RUINED BECAUSE OF ALL THE OIL THROWN . THEY AGREED TO PAY FOR THE CONVERTER BUT I HAD TO PAY FOR THE LABOR (?)

Recall on my 2017 Hyundai Sonata was repaired 9/13/2019, purchased the vehicle with financing on 7/16/2021. On 8/18/2021, had vehicle towed back to the dealership and explained the issue. Engine knocking, tire pressure and engine lights on, frequent stalling, turning off, smell of gas and something burning, loss of power to the engine, car could not accelerate to 60 MPH. The dealership had my car till 9/20/2021, power train warranty was denied and voided, no loaner car was given, was not offered any reimbursement for car rental by dealership and Hyundai corporate. Although car is included in Theta class action lawsuit. I was correct about issue with engine, but the dealership replaced engine with used parts. No later than five days after having my car back, the engine and tire pressure lights came back on, car is tugging, and the engine noise is louder. I don’t believe that they replaced the engine with OEM parts.

The contact owns a 2017 Hyundai Sonata. The contact stated that while merging onto a highway at 50 MPH, the vehicle independently decelerated to 30 MPH and shifted into limp mode. The contact stated that an unknown warning light was illuminated on the instrument panel. The contact had initially taken the vehicle to an independent mechanic who was unable to determine the cause of the failure. The contact then had the vehicle towed to a dealer where he was informed that the failure was linked to a software update. The manufacturer was not notified of the failure. The failure mileage was 56,000.

I BOUGHT THE CAR USED FROM A SCAM DEALERSHIP. I HAD NO IDEA THAT THERE WAS AN ENGINE RECALL IN JANUARY UNTIL IT TURNED OFF AND ON JUST ONE WEEK AFTER LEAVING THE LOT. I BROUGHT IT BACK TO THEM, OBVIOUSLY, THEY SAID IT WASN'T THEIR PROBLEM. I THEN TOOK IT TO COLLEGE PARK HYUNDAI TO HAVE THEM UPDATE THE KNOCK SENSOR AND DIAGNOSE THE ISSUE. AFTER AN EXTENDED ROAD TEST, IT WAS DECIDED THAT MY PROBLEM WAS AN ISOLATED INCIDENT. YET I TOOK IT TO OTHER DEALERSHIPS, AND PRETTY MUCH EVERYONE SAYS THE SAME. MY DASH CAM HAS RECORDED THE MOMENTS WHEN THE CAR STUTTERS AND FAILS TO ACCELERATE BEFORE TURNING BACK ON A COUPLE SECONDS LATER. IT HAS HAPPENED ON CURVES AND I HAVE NEARLY DROVE OFF THE HIGHWAY DUE TO THIS. IT ONLY HAPPENS WHEN THE CAR IS REACHING ABOUT 60MPH. I LIVE IN MD BUT WORK IN VA.

FINALLY DIAGNOSED THE PROBLEM TO BE A MISSING CIRCLIP ("C" CLIP) THAT HOLDS THE CV AXLE IN THE TRANSMISSION CASE. WITHOUT IT, THE AXLE ITSELF WAS WORKING ITS WAY OUT OF THE TRANSMISSION CASE, AND VIBRATING BECAUSE OF ITS LOOSENESS. RESEARCHED THE PROBLEM AND FOUND THAT FULL SEPARATION OF THE AXLE FROM THE TRANSMISSION COULD RESULT IN UNCONTROLLED BEHAVIOR OF CAR, AND INEVITABLE ACCIDENT OR WORSE. THIS WAS A MANUFACTURING/ASSEMBLY ERROR, AND COULD BE A SYSTEMIC PROBLEM IN THE ASSEMBLY PROCESS. THE REPAIR WAS PERFORMED BY THE DEALERSHIP UNDER WARRANTY, BUT THIS COULD PRESENT A DANGEROUS RISK TO OTHER 2017 SONATA PURCHASERS, SO I WRITE THIS COMPLAINT AS BOTH A CIVIC RIGHT AND A RESPONSIBLE CITIZEN. WHEN DISCUSSING THIS ISSUE WITH A HYUNDAI REPRESENTATIVE, I WAS TOLD IN BLUNT AND NO UNCERTAIN TERMS THAT THE PROBLEM WAS RESOLVED AND THERE WAS NO FURTHER ACTION OR DISCUSSION THAT WAS NECESSARY. OUR PRIOR 2011 HYUNDAI'S ENGINE HAD SEIZED AT HIGHWAY SPEED, AND MY WIFE LOST ALL POWER STEERING AND BRAKING. DESPITE SAFETY ISSUES WITH BOTH 2011 AND 2017 SONATAS, THERE WAS NO ACKNOWLEDGEMENT NOR ADMISSION OF ACCOUNTABILITY. I WOULD LIKE TO BE REASSURED THAT THIS AXLE CIRCLIP PROBLEM IS ACKNOWLEDGED AND RECTIFIED, AS THE GREATER SAFETY OF SONATA OWNERS MAY BE AT RISK. WE PERSONALLY NOW FEEL UNSAFE IN THE SONATA MODEL, AND ONLY PURCHASED A SECOND ONE UNDER THE ASSUMPTION THAT LIGHTNING DOESN'T STRIKE TWICE... THIS IS NOT SO...

MY VEHICLE WAS IN PARK ON MY STREET. MY HUSBAND WAS IN THE PASSENGER SEAT. I EXITED THE DRIVER SIDE OF THE VEHICLE AND OPENED THE DRIVER SIDE REAR DOOR. I KNEELED ON THE SEAT TO REACH BEHIND THE PASSENGER SIDE SEAT TO GRAB MY LAUNDRY BASKET. THE CAR BEGAN TO ROLL BACKWARDS. WE HIT A VEHICLE DIRECTLY BEHIND US AND ENDED UP IN OUR NEIGHBORS YARD. WE CONTACTED THE POLICE AND A TOW TRUCK WAS SENT. THE TOW TRUCK ARRIVED FROM JOYCE'S TOWING ON MT. NEBO ROAD IN PITTSBURGH PA. THE TOW TRUCK DRIVER NOTICED THAT WHILE THE CAR WAS IN PARK THE WHEELS WERE SPINNING. THE BODY SHOP IN WHICH WE TOOK OUR VEHICLE TO, IS HAVING AN ISSUE TRYING TO DUPLICATE THE PROBLEM. IN THE MEANTIME, I DO NOT FEEL THAT OUR VEHICLE IS SAFE, AND DO NOT WANT TO RISK THIS INCIDENT HAPPENING AGAIN, BEING THAT IT WAS AN ISSUE IN 2011-2014 HYUNDAI SONATAS.

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

TL* THE CONTACT OWNS A 2017 HYUNDAI SONATA. WHILE PARKING THE VEHICLE AND SHIFTING INTO REVERSE, THE REAR CAMERA FAILED TO DISPLAY AN IMAGE ON THE MONITOR. ALSO, THE LIGHTS AROUND THE MONITOR AND THE GEAR SHIFTER FAILED TO ILLUMINATE. THE CONTACT STATED THAT HE WAS ABLE TO SHIFT THE VEHICLE INTO PARK. UPON ATTEMPTING TO SHIFT BACK INTO REVERSE, THE GEAR SHIFTER FAILED TO MOVE. THE VEHICLE WAS THEN TURNED OFF AND RESTARTED AND OPERATED CORRECTLY AFTER A FEW MINUTES. THE CONTACT ALSO MENTIONED THAT A RATTLING NOISE WAS HEARD IN THE FRONT OF THE VEHICLE FOR 15 MINUTES AFTER STARTING THE VEHICLE AND DRIVING. THE VEHICLE WAS NOT TAKEN TO AN INDEPENDENT MECHANIC OR DEALER FOR DIAGNOSTIC TESTING OR REPAIRS. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURES. THE FAILURE MILEAGE WAS APPROXIMATELY 800.

DRIVING TO WORK VEHICLE LOST POWER IN PARKING GARAGE, DURING BUSIEST TIME AND LOT OF TRAFFIC IN GARAGE. CAR FELT LIKE IT WAS COASTING, PRESSING THE GAS PEDAL AND NOTHING, THEN FLOORED THE PEDAL AND IT REVVED UP ENOUGH TO GET ME UP THE RAMP INTO A PARKING SPOT. ENGINE WARNING LIGHT CAME ON. THANKFULLY THIS DIDN'T HAPPEN ON THE FREEWAY. TOWED TO DEALERSHIP, THEY DON'T KNOW WHAT IS WRONG, THE CAR IS STILL IN THE SHOP.
