The engine lamp turned yellow. The car got inspected by a mechanic and showed code. P052E, which indicates the defect in the crankcase ventilation valve. I see that many cars of the same model in which were produced about the same year had the same defect. I called the manufacture customer service and they claim that my van was not included in the recall. My vehicle likely had the same problem as other people did in the past, but for some reason my vin was not included.

failed piston wrist pins from early production of mercedes w205 c300. The issue was diagnosed by mercedes of manhattan and could not provide me a fix.

Crank case vent valve assembly

My 2015 Mercedes Benz vehicle is rarely driven as I took public transportation to work and has ~55000 miles. However, the engine has started throwing error code P052E verified by an independent dealer - crankcase ventilation valve failure. It means the engine could shut off amid driving and I did research and it seems like a very common issue that Mercedes Benz car owner encounter and feels like a severe car defect.

I keep getting the P052E PCV replacement valve issue. I see online that this has impacted multiple Mercedes C class but no recalls have been issued for this.

Was driving on the highway , car was running for about 7-10 min from the start , and when took off from exit , car started to shake and when pulled off to the side of the road , the car won’t start anymore , dealership said that engine failed ,

My car is registering code P052E71. The diagnosis says the valve for crankcase ventilation has a malfunction. The actuator is blocked. This is a common problem for this car with research. Some people have had to replace this part multiple times for their Mercedes which is a part that shouldn't fail. Nothing has been done such as a recall on this vehicle. The part and labor to repair this issue costs $1000+ dollars. Something should be done to help consumers. I'm doing my part to report this hoping something will be done.

My check engine light came on recently on my 2015 C300 4matic. Car has 66500 miles on it. The code P052E71 was diagnosed - The valve for the crankcase ventilation has a malfunction. The actuator was blocked. This problems seems to be occurring to a lot of similar cars from Mercedes and some of them have reported that this issue keeps coming back. The dealership and other auto body shops say it's going to cost around $1500-$2000, considering how it's a tedious job to do and involves multiple hours of labor. The dealer won't repair it as part of warranty. This definitely seems to be an engine issue with the car and has nothing to do with how we drive. Cars not older than a couple years are starting to see this issue. There needs to be a recall for this and have Mercedes does something about it. Why are the consumers having to spend money to have the same repairs done for a bad design, parts and engine being provided by Mercedes.

The valve for crankcase ventilation has a malfunction. The actuator is blocked. Seems like its a common problem for all mercedes C300 ~2015 models. The part should be recalled.

After getting gas my check engine came on steady. Stayed on until cleared. After getting gas a 2nd time check engine light came on again, stayed on, but went out. Then after getting gas a 3rd time, check engine light came on again. Checked by a local Mercedes shop, code showed intake line oil separator bad.

2015 MB C300 Check engine light came on, appointment scheduled to check issue before it went to the mechanic had a safety issue when accelerating to turn in a seven lane busy intersection the car lost acceleration and missed, running rough for a few seconds then recovered in time for me to get out of the way of the 45-50 mph oncoming traffic. Issue is P052E positive crank case ventilation valve which is going to cost $2200 to fix. Car has just over 60k miles on it and this is a known issue for YEARS on multiple MB turbocharged 4cl. I could have been t-boned if the acceleration hadn’t recovered. Does someone have to get killed before MB recalls the vehicles? 60k miles is not a lot of mileage for a car 8 years old that has had all its scheduled maintenance.

Safety concerns: The vehicle is not able to pass an emissions test with the engine light engaged. Per America Service Center in Arlington, VA, which is the only service center that has serviced the vehicle during my ownership, they commented and documented that oil is entering through a vent valve. My additional concerns are: If an odorless fume is passing into the passenger cabin and the vehicle can not pass state emissions these are immediate concerns. The service center advices that I may continue to drive the vehicle. However, I am concerned should the oil fully empty without warning the vehicle may fail while in use on a dangerous roadway due to cause and effect of additional unknown maintenance related operational co-dependent mechanical components.

Crank case breather assembly needed replacement at 31,200 miles. Service mech. Advised the leaking area (oil) could not be repaired since Mercedes does not sell replacement parts and entire assembly needs to be replaced. March advised Mercedes is aware of issue and has redesigned the entire assembly. Cost for part was $400+ and labor to install was $1000. This issue is common as seen on internet and should warrant a recall refund to customers.

Positive Crankcase Valve faulty causing car to buck during moderate acceleration especially when accelerating onto an interstate on an on ramp.

My vehicle is a 2015 C300 AWD. One day I was driving on the highway and noticed white smoke coming out of the exhaust. The check engine light came on shortly after as I pulled over. Being that I was less than a mile from my house, I decided to go park the vehicle. I noticed that it was losing power and had problems going above 45mph. Since my vehicle had 99k miles. I took it to my indy mechanic that has worked on the vehicle since it has been out of warranty. When he diagnosed the vehicle, 48 codes came up. He suggested we change the spark plugs and coils, which we did. Didn't fix the problem. Then he suggested we change fuel injector 1, which we did. That didn't solve the problem. I decided to take it to the local Mercedes dealership where they did another diagnostic test. And like many others here, cracked piston/cylinder 1 dead. I'm looking at $18,000 in repairs. I told them no thank you. The car is now sitting in my garage. I really hope Mercedes makes this right with its customers. There is no reason why this many people should be having this exact same problem. Vehicle Symptoms: White smoke out of exhaust Check engine light on Cylinder 1 Misfire Burning Oil Causing loss of power Radio randomly shuts off & went into Anti Theft Mode

2015 C300 Crankcase Ventilation Valve Replacement P052E71 NEED TO BE REPLACED, ENGINE LIGHT COMES ON. ONLY HAVE 37,000 MILES MANY REPORTS OF THIS ISSUE

my car is a 2015 C300 class Mercedes-Benz, as I was driving, the car suddenly and without warning began to vibrate and shake violently and immediately lost power. Fortunately I was off the freeway, a serious accident could have resulted. I took it to the the local MB dealership and they told me that the car failed a compression test in the #1 cylinder and that the engine would have to be replaced at almost $17000. Of course, this was beyond warranty, Mercedes know it’s a defective product, they refused to act responsibly. This cracked piston which is a design flaw by Mercedes needs to be recalled, a lot of people are reporting the same issue.

The problem is actually a manufacturing defect in the wrist pins. The defective parts are in engines made before April 20, 2015 which is mine. If left unrepaired, it causes premature wear in the cylinder walls. The issue on my car been confirmed by mb dealer.

obd2 scanner reported Error Code P052E which seems a very common issues on Mercedes C class 2015 or newer and there is no recall issued by Mercedes Benz yet which points out to possible problems with "PCV Regulator Valve components. There are 100s of post in the forum related to same issue

My son's car was blowing white smoke out of the exhaust and had a sweet burning smell and the check engine light came on. The crankcase vent valve is needing to be replaced on this 2015 C300 Mercedes Benz and many owners of this same type of car (different year) are posting about it. Owners of these types of cars are saying that replacement is happening more than once! That it's a common defect of these cars. My son has less than 100,000 miles (61,000 if that) and this shouldn't be happening. And, it's time someone does something to protect the consumer. Mercedes-Benz dealers are taking advantage of consumers and charging ridiculous prices to replace this part, but the part shouldn't be breaking. It's a safety factor in that it can affect driving, there's risk of blowing valves/valve cap and engines, including loss of the vehicle and nowadays no one can afford to buy a new car or even a used one! Consumers buy what they think is a reliable vehicle but Mercedes isn't taking care of their customers. Mercedes-Benz should be forced to do a recall and replace these faulty parts.

Driving the 2015 c300 with approx. 69k in miles down the highway and heard a pop and the check engine light came on. The next day there was a rough idle and clanging at low speeds. took to dealership and they quoted me $15k in repairs for a new engine. MB tech said the cylinder #1 is out of spec., and there is scoring on cylinder wall caused by the piston being off center and riding the cylinder wall. After doing research this is a common problem with the m274 engine. How has this not been recalled and taken care of by Mercedes?? At this point i am 'forced' to either come up with $15k for the repairs, or go to MB dealership and try to get into a new car...which i am over $12k upside down on i might add

Check engine light came on and strong fuel smell. Crankcase ventilation malfunction code was verified by dealer.

When driving I accelerated and then the engine light turned on. after that the car was jolty and turned off completely when stopped. had to force a restart at the light. code that came back was p052E. This is a major and common issue with these cars. part is 400+ dollars. labor is much more since this is a 6 hour job. the work to replace this part is incredibly intensive that makes it impossible for regular car owners to change. Mercedes refuses to recognizes this as a common issue. but the truth is they designed a faulty system that they claim to have updated a handful of times now.

My check engine light was on when I was driving on the highway. I was terrified that something was very wrong. Right after, I took the car to the dealer and was told that the valve for the crankcase ventilation. The actuator was blocked. I was also told that this is not caused by something I did. It's the design of the car that caused the problem.

P052e71 positive crankcase ventilation regularly valve issue. This is a common issue Mercedes is aware of with their vehicles. I was quoted 1600+ for a repair for something has been known about for over 7 years to be an issue with the car class. I was also told by the shop that this a very common issue and odds are I would need the same service within a year or two.

Oil separator failure. This a common design fault as documented by multiple complaints on the internet. This is another Mercedes Benz emission design flaw causing emission failures. This is very cheap part but extremely expensive to replace. Mercedes collects over $1200 per labor repair for each. THIS IS AN EMISSIONS POLLUTION AND SAFETY ISSUE THAT CAN BE SOLVED. PLEASE FORCE A RECALL. Engine severely smokes/stalls leaving people stranded on highways. When stuck, coolant is sucked into the engine mixing with the oil. No warning. The car

I have 2015 C300 Model, total milage on the car is 30K. Dashboard is showing the check engine light and when I take to Dealership for diagnostic, the code is P052E which is a problem with Crankcase vent. Dealership tech had mentioned that this seems to be known issue effecting years 2015-2018. When I did search, he is right; many MB owners are facing same issue which is a malfunction during assembly/manufacturing. MB should be responsible for part replacement and labor. Please investigate and ask MB to run recall campaign. Thank You.

Vehicle experienced loss of power and rough running when check engine light came on. Mercedes dealer reported one of the pistons cracked resulting in catastrophic engine failure with just shy of 61,880 miles on it.

These cars have a known wrist pin failure, mercedes refuses to cover the cost of repairs as its not a recall. My vehicle is the specific model and year this is known for, and my car is making these piston slapping sounds, worse everyday. Worse on deceleration, goes away when warmed up, just like the reports. I am afraid I'll lose power while driving and hurt myself or others.

I have an emissions related Check Engine Light (P052E71) relating to the Evaporative/Crankcase ventilation system. I think this should be a Recalled/Warrantee item on the 10 year/100,000 miles federally mandated guarantee. Please advise...

It cuts out randomly while pressing the gas pedel to get out of the way of traffic and cuts out and stalls ive had it looked at and they say theres no check engine codes and that they cant make it do it. Theres many of people with the same issue online and the dealers wont help them either

Common problem mercedes hasn’t addressed from the factory crankcase breather element at less than 50,000 miles and the smell pf gas that comes in to the cabin is horrible

The dealership is staying I have an issue with the crankcase valve vent and this seems to be a known issue effecting years 2015-2018.

2015 Mercedes C300 crankcase ventilation regularly valve is garbage, have to spend around $2K to get it replaced. Very common issue for this model.

Car is at 60,000 Miles and code for Positive crankcase ventilation appeared. Why does this happen to a trouble free car after warranty runs out?????????? Seems like hundreds of complaints all over the internet and Dealer charging big money to fix their design Flaws.

Crankcase (pcv) problem of the 2015 Mercedes Benz C300 Diagnosis code p052e pcv regulator valve replacement/crankcase replacement. The code keeps coming back with check engine light on dashboard. To replace part, the engine has to be taken down since the crankcase is inside the engine. This is a malfunction during assembly/manufacturing, it is impossible to damage part while under usage. Mercedes benz should be held responsible for part replacement and labor. This is a common defect and should be recalled.

Crankcase ventilation valve malfunctioning Second time with car. Creating trapped exhaust in crankcase.

Mercedes crankcase ventilation valve has failed, error P052E71. Found that this is happening to thousands of other Mercedes c300, and even after it is fixed it happens again. Reporting this so hopefully it can be resolved with a recall.

Vehicle throwing P052E error (crankcase ventilation valve - PCV) - Has occurred multiple times and has effected numerous C300 models of the years 2015-18. - The car has lower acceleration performance and can be potentially dangerous when merging on highways.

Check engine light came on and gave code P052E PCV Regulator Valve Performance

Cracked cylinder #1. Causes rough idle, loss of power and lots of white smoke out the tail pipe. This is dangerous for anyone behind the car trying to see through the smoke then loosing power and other vehicles almost hitting me. Mercedes know they are defective but because of the large cost associated with repairing them they will not fix.

Cylinder #1 losing compression. Onset acute after exiting freeway. Car lost power. Engine warning light turned on. Independent repair shop advised compression problem in Cylinder #1. Dealer then inspected and advised there was compression loss in Cylinder #1. Dealer recommended engine replacement (not repair). The car only has around 46,000 miles and is a 2015 model.

The crankcase ventilation valve has gone out on my car. This is a continual problem with these vehicles at low mileage. Mercedes Benz should recall the part for repair as they stated it could damage the engine.

PCV (Positive Crank Ventilation) error fault. Error message keeps coming and is affecting a large number of vehicles.

MY VEHICLE'S Positive Crankcase ventilation valve NEEDS REPLACING. AFTER RESEARCHING THIS ISSUE FOR A WEEK IM LEARNING THAT THIS IS A VERY COMMON ISSUE WITH MY VEHICLE'S MAKE MODEL AND YEAR AND IS LIKELY TO OCCUR MORE THAN ONE TIME IN THE VEHILES LIFETIME. THE PROBLEM HAS BEEN CONFIRMED BY AN INDEPENDENT SERVICE CENTER I WAS MADE AWARE OF THE ISSUE BY MY VEHICLE'S CHECK ENGIN LIGHT

I keep getting a litany of warnings on the dash.

This vehicle has a known issue of the timing chain needing replacement around 80,000 miles. When I hit approx. 78,000 miles i started hearing strange sounds and issues with my vehicle starting so I took my vehicle to a local mechanic and he said that the timing chain needs to be replaced. he also stated that there should be a recall on this issue as there has been a recall on the same vehicle for the same issue just a different year which has the same exact engine therefore this year of vehicle should also have the recall applied for the timing chain to be repaired. This issue is causing engine problems and will eventually lead to the engine completely blowing at any time now.

I got a P052E code on my car which means a faulty crankcase or PCV valve. After doing some reading it seems to be a super common problem.

Long story short, I own a 2015 C300 Mercedes with 59,500 miles I was driving on the street when my engine started shaking so rough and my car lost power. I panicked and pulled over and drove 10mph all the way home. My vehicle would shake rough, couldn’t exceed 10mph and would make loud noises. I take it to the Keyes Mercedes dealership and they tell me it’s a cracked piston. I couldn’t believe it because I only have 59k miles. I have my vehicle records so I have been up to date on my maintenance. They dissembled my engine and couldn’t find the cause to the failure but found the cracked piston in cylinder #1 and damage to the cylinder walls. They recommended to replace complete engine and it will cost me about more than $18,000!! The piston falls under Mercedes 7 year/70k miles emissions warranty and yet they deny coverage. After doing lots of research I come to find out that I’m not the only victim that has suffered the exact damage. People that also own a Mercedes c300 and other models are now without a vehicle and looking at a repair of $18k+ and making a car payment for nothing. This has caused us stress, inconvenience, and damage to our mental health. Keyes Mercedes located in Van Nuys is also aware of the common cracked piston issues on their vehicles. In 2 days I mark 4 months without my car. Please help!!

Car has 51,000 miles , no check engine light or any other warning light .driving in on the freeway at 70 mph when I hear a pop sound and my car loses power , I pushed on the gas and it started to shake violently and I panicked as the construction on the freeway was not allowing drivers a shoulder to pull over on . I was lucky enough to be driving at 2am and with the construction going on , drivers were already slowing down . My car also started blowing a thick white smoke through the back exhaust that could have made it harder to see that late night as it was already foggy here in California . At first I didn’t realize I was smoking through the back until my car began smelling like burnt oil . I wasn’t able to get off the freeway until the next exit all while thinking that my car was going to explode from the smell of the burning oil . When I pulled over and got out of the car I made sure I didn’t see any fire and then I waited to let it cool down , opened the hood and saw oil everywhere . I had it towed to Mercedes and I got the problem and the estimated cost to repair it . The problem turned out being a cracked piston in cylinder one , when it cracked it allowed oil to mix with the gasoline and that’s what was causing all the white smoke out the rear , the burnt smell was from the oil that was leaked all over my engine getting too hot from the engine. I found out a few days ago that Mercedes’ has a technical billeting regarding a faulty wrist pin that was causing the pistons to eventually crack . In the bulletin the faulty pin problem is fixed by replacing all the pistons and adding a upgraded pin and many other parts . So there are many other drivers that are experiencing this and driving with faulty wrist pins . Prior to all this happening the car always made a tap tap tap sound from engine and Mercedes’ said it was normal for 4cylinder turbos to make this sound, sounded like a diesel . But it turned out being from the loose wrist pin . Mercedes lied to us . THE CONSUMER REQUESTED THAT MERCEDES BENZ VEHICLE

The contact owned a 2015 Mercedes-Benz C300. The contact stated that while idle, the engine would vibrate with an abnormal sputtering sound coming from the engine. As the failure persisted, the check engine warning light illuminated. The contact had initially taken the vehicle to a dealer and the spark plugs were replaced; however, the failure persisted. The vehicle was returned to the dealer and a diagnostic test was performed, and it was discovered that an engine cylinder had blown. The vehicle was diagnosed with engine failure and the contact was provided an estimate for the repair. The contact then spoke to an independent mechanic who informed her that the failure was a common failure for her model vehicle. The manufacturer was also notified of the failure and a case was filed. An email was sent to the manufacturer and the contact was informed that no further assistance could be offered. The vehicle was not repaired. The failure mileage was approximately 50,900.

Mileage: 50,900

The wrist pin is defective in early engines during manufacturing. It is not safe to operate the vehicle because at any time without any warning this can cause fatal damage to the engine - piston crack resulting in total loss of control even at high speeds on the highway. Numerous complaints were filed on NHTSA regarding cracked pistons most likely related to this wrist pin manufacture defect. The problem is acknowledged by M-BENZ (NHTSA ID Number: 10058545), and starting around April 20 2015 M-BENZ started to install modified wrist pins to prevent future failures, but they did not address existing faulty wrist pins. The vehicle was always serviced at the official MBENZ Dealer service and was under comprehensive inspection multiple times but the issue was never acknowledged by the service technicians during the warranty period even though the issue existed since manufacturing and instruction of how to diagnose was distributed between service technicians via Manufacturer Communication Number: LI03-10P060916 in 2015. When the M-BENZ Delear service technician finally confirmed the issue, the vehicle was already out of warranty and there is a hefty price to a customer to fix this manufacturer defect that should not have been there in the first place. There are no warning lamps, messages, or other easily detectable symptoms of the problem prior to the failure. The issue can be diagnosed under very special conditions described in Manufacturer Communication Number: LI03-10P060916 For most drivers, it's hard to diagnose that something is wrong and easily mistaken for normal operation noise of the engine

Without any warring or indication my engine would start making bad noise then light comes on to check engine as the motor fails and car shuts off. This is while driving and has happened two times now. Both times I find it’s due to spark plug failure and pieces of the plug go throughout the engine and severely damage. First time this happened at 82,000 miles and was covered by warranty. Now this has happened again on the new engine with 81000 miles on it. I seen many forums on this issue. This time it’s not under warranty and it’s $18000 to fix. Mercedes Benz w205 engine seems to be notorious for spark plug failure in cylinder 1 as well as piston cracking. The first time this happened was October 12th 2019 and the warranty work was done at fletcher Jones Mercedes Benz of Newport Beach

Check engine light came on. Code P052E. Had this code in 2018 and the pcv valve and line were changed. Currently has the same issue 3 years later. This is a very common problem with mercedes that have this engine.

The engine stalled at idle numerous times when at a stop light or stop sign. This was dangerous as the other cars could have ran into my car in anticipation that I should be moving with traffic. The car was taken to the Mercedes Marin dealer service center and diagnostic was done indicating a cracked piston in cylinder one was causing loss of compression and could also cause engine failure at speed if not taken care of. Check engine light DID NOT come on. During research on repairs for this issue, it became apparent that Mercedes Benz is aware of this issue in many of its engines of this model and year, but did nothing to remedy the situation or the underlying manufacturing defect that causes the cracked piston. In addition, Mercedes is unwilling to cover the cost of repair or replacement (car has only. 49,000 miles, but is out of warranty due to age).

In March of 2020 I was driving home from work. I stopped at a red light. When it turned green, I proceeded to step on the gas. My car started making noises and shaking as I drove. My check engine light came on. I was able to pull over without incident. My vehicle has under 48k miles on it! I had it towed to a Firestone facility by my house. They replaced spark plugs and ignition coil 1 and 2. They said it was still severely misfiring. Cylinder 1 must have internal damage and should be towed to the dealer. They gave me a spark plug they removed that had significant damage to the top part. They said something must have impacted it with significant force. I then had the vehicle towed to a Mercedes Benz Dealership. They said they inspected with a scope and found piston material missing, can see ring exposed and have damage to cylinder wall. Will need to replace engine, turbo charger, cat converter intake manifold to repair. They wanted $18k to repair. I did some research and found out that the 2015 Mercedes C class was the first year they switched from 6 cylinder to 4 cylinder turbo charge engine. These models have had a significant amount of engine problems and failures, the manufacturer is aware of. Many of these occurred in cylinder 1 along with wrist pins issues and others. I found my situation wasn't unique. I then filed a complaint with The BBB in Georgia. MBUSA offered me $3k towards the repair or purchase of a new vehicle. I declined the offer. I only wanted my vehicle repaired. I wasn't alone in this situation. These issues are easily found online. My vehicle has since been sitting in my driveway for almost a year and a half. I've been making my monthly car and insurance payments on a vehicle I can't drive. I recently went to the Mercedes dealership and they will give me $5k for the vehicle towards a trade, leaving me with $15k negative equity towards the purchase of a vehicle. Mercedes should stand behind their products and do the right thing

I was in middle line on I-5 SB San Diego doing 40-60MPH when my car suddenly started to shudder, shake and smoke came from the exhaust. The car lost power and the check-engine light came on right away. I was told that Cylinder 3 lost pressure, that the engine wall was damaged and that possibly the piston and wrist pin are cracked. My car has only 66K miles and the Mercedes Benz dealership is telling me that I need a new engine that will cost $19,000. After doing some research I have found out that I wasn't the only one with this issue. I have listed an example here: "HERE IS A MAJOR ISSUE WITH THE 2015 M274 MERCEDES ENGINE REGARDING THE WRIST PINS. MERCEDES HAS ISSUED NUMEROUS INTERNAL SERVICE BULLETINS ABOUT THE ISSUE. THE ENGINES WERE MANUFACTURED WITH WRIST PINS WITH TOO MUCH TOLERANCE THAT SLAP AGAINST THE PISTON WHEN OPERATING THAT COULD LEAD TO PREMATURE ENGINE FAILURES. THERE ARE HUNDREDS OF COMPLAINTS ON ONLINE FORUMS OF PREMATURE ENGINE FAILURES (PRE 100K MILES)." MBUSA requested from me proof that the car was serviced on time and with the correct parts. Once I was able to prove everything they told me that they were sorry but I still need to pay for everything. They did offer a "10% good-will discount". I wish they told me when I was buying a car that after every 6th oil change I will need a new engine. PLEASE MAKE MERCEDES MAKE THIS RIGHT AND FIX THE AFFECTED CARS THE RIGHT WAY.

DONT KNOW WHICH CATEGORY IT FALLS. I BOUGHT THIS CAR IN AUGUST 2015. IN ONE WEEK IT WOULD NOT START EVEN. TOWED TO DEALERSHIP AND THEY SAID, THE GROUNDING SCREW WAS LOOSE. I AM SO SURPRISED THAT A CAR COMES OUT FROM FACTORY WITH A LOOSE GROUNDING ISSUE. IN THE LAST 2 WEEKS, THE CAR JUST STALLED AT THE SIGNAL. ALL LIGHTS CAME UP. I HAD THE ECO START/STOP MODE ON. THIS HAPPENED 3 TIMES AND FINALLY I SHUT THE ECO START/STOP MODE DOWN. IT IS SO DANGEROUS THAT IN HEAVY TRAFFIC, WHEN PEOPLE ARE READY TO DRIVE ON CHANGE OF SIGNAL, THE CAR WONT MOVE, PEOPLE ARE HONKING AND FRUSTRATED AND I AM TOO. LOOKED ONLINE AND SO MANY PEOPLE ARE COMPLAINING THE SAME. THE WHOLE OF DASHBOARD LIGHTS UP LIKE WHEN A CAR STALLS. THIS IS VERY DANGEROUS. ANYBODY WAITING BEHIND YOU CAN TAKE THE PEDAL FROM THE BRAKE AND SMASH INTO YOU. SIMILARLY, FOR LAST 2 MONTHS, I HAVE NOTICED THAT THERE IS A JUMPING NATURE WHEN YOU TAKE LEG OF THE BRAKE AT THE SIGNAL. THAT SCARES ME AS WELL.
