Service Brakes Problems of Chevrolet Volt - part 2

Anytime the vehicle goes over bump, pothole, or particularly rough road surface at the same time that the brake pedal is depressed, the brakes do not engage and the vehicle fails to slow down. You must release the pedal and apply pressure a second time in order to stop. This occurs when the vehicle is in motion at any speed.

We own two 2017 chevy Volts. Both have two issues: 1) often cruise control does always stay engaged due to brake pedal slipping to a very slight depressed position. 2) shift-to-park- cars will not properly go into park sometimes and thus cannot be turned off. These two issues are clearly manufacturer defects as both cars were bought new and within a month of each other. I will enter this for my other VIN number as well. These have been ongoing issues that we are having to spend money to correct and there are many reports of these being issues, yet there is no recall. We purchased both cars brand new within a month of each other. Both issues have been ongoing and have occured more than once.

Purchased a 2107 Volt premier with 40k miles in July 2020. My wife was driving the car and it lost power on the freeway with a "shift to park" warning and check engine light. She was able to glide over to the shoulder and I came to rescue her. After repeated on off cycles I got the car to move a couple of miles with several "jerking" motions while driving then it died again and I lost power braking (went to manual only). This time I was unable to "re-boot it" and had onstar have it towed to a local chevy dealer who has a "certified ev specialist".

My 2016 Chevrolet Volt is exhibiting the "shift to park" issue. More often than not, when I shift to park and attempt to shut my car off, it alerts me that I need to shift in order to park. I have to turn the car back on, then turn it off again, sometimes I move the shifter or flick the shifter button to fix it.

After fully charged my car, I pulled out of the parking garage and into an available parking stall at work on Friday January 24th 2020 at approximately 1:50pm. I let my car cruise into the stall while my foot is covering the brakes. Halfway into the parking stall, the car accelerated on its own. I applied the brakes but did not help. It stopped only when it jumped the front concrete stall with 2 front wheels and hit the trees then rolled back. I then immediately shift the gear to park. The day was sunny and road condition was dry. I was fortunate that it hit the trees and not other cars if I were to take this out on the road. The attached pictures shows tire marks as I am trying to brake and the tire wears.

The contact owned a 2016 Chevrolet Volt. The contact stated that while driving approximately 35 mph, the message service stabilitrak suddenly displayed. The brake pedal was still and the steering wheel failed to respond when turned as a result control of the vehicle was lost and the contact crashed into a bluff. The vehicle was destroyed. The driver sustained a sore body due to the impact and medical attention was not sought. No police report was filed. The vehicle was towed away. The local dealer (unknown) was called and informed that the vehicle was destroyed but the failure experienced was not discussed. The manufacturer was not notified of the failure. The failure mileage was 177,000.

Radiator leak.

After diagnosing an audible tick/click sound that occurs whether the car is powered on or off but stops momentarily when the brake pedal is applied, I was told the electric brake booster is bad and must be replaced. But gm has no parts available. I was told to drive the car and if the part fails completely, I will have no brakes at all. It has been over 3 weeks and there is no eta on parts.

Breaks failed while driving 25-30 mph on windy mountain road . There was no warning , car started to accelerate downhill gradually . After about 0. 3 miles I was able to finally push emergency breaks (it's a button and didn't work at first ) get to more flat road and stoped the car by driving on gravel and dry brush . Vehicle completely lost its power about 2-3 minutes later . Emergency lights didn't work . Chp assisted us as car was abandoned in the middle of mountain road , blocking the whole line . Gm has not offered any explanation yet .

Leasing 2019 chevy Volt from dgdg chevy: end of September -- major safety issue (brakes): end of September 2019, the vehicle had limited brake power (check engine light on and traction control disabled). When braking, the car makes very loud (system noise) and skids while braking. After nearly crashing the car couple of times in the highway (due to very poor braking), car was turned into chevy dgdg and problem was confirmed. Car was returned back second week of October and initial issues went away. First week of December 2019 -- more brake problems / risk to drivers brake issue had returned (limited brake power; skids while braking, makes loud beeping noise, check engine light on/traction control off). I bought it back to the same dealership, after nearly rear ending few cars due to the malfunction of the brake. Issue was confirmed and was in the shop for over 70days+. Car was returned after replacing the brake system. First week of February 2020, same issue occurred after less than week of receiving my car back (took more than 70days in the shop). Same issue, brakes are not functioning properly, almost rear ended someone again, as a result of it. Shop is taking a look at it again. I'm writing this report in hopes of gaining attention of this major safety issue which is putting my life, and others at risk, working with chevy. I have the fear that this problem can occur again, based on previous attempts, and no real resolution.

Tl- the contact owns a 2012 Chevrolet Volt. The contact stated that while driving approximately 25 mph, when a vehicle in front suddenly stopped causing the contact to suddenly press the brakes. The contact stated that since that incident every time they applied pressure to the brake pedal the vehicle would shake and the brake assist warning light illuminated. The contact took the vehicle to the dealership (simpson Chevrolet of irvine located at 21 auto center dr, irvine, CA 92618 phone number: 949-328-6026) who stated that the electronic brake control module and brake pressure modulator valve failed and needed to be replaced. The vehicle had not been repaired. The contact stated their failure related to NHTSA campaign number: 13v271000 (electronic stability control, service brakes) however, the VIN was not included in the recall. The manufacturer was made aware of the failure and opened case number: 9-5532753956. The approximate failure mileage was 120,000. Gl.

Tl- the contact owns a 2013 Chevrolet Volt. The contact stated that while driving at various speeds, when the brake pedal was depressed the vehicle jerked. The contact mentioned that the air bag warning light was illuminated. The vehicle was taken to south charlotte Chevrolet 9325 south blvd, charlotte, nc 28273 (704) 444-0109 where the brake modulator value was replaced. The vehicle was repaired. The manufacture was made aware of the failure. The failure mileage was 73,625. Dr.

While driving on city streets and highways, the adaptive cruise control will not engage 25% of the time and will disengage without notice. "adaptive cruise control will appear in dic. However, this creates a safety hazard as you never know if the car will automatically slow down. I have filed case # 9-5379585813 with Chevrolet and been to four dealers and they refuse to fix the problem. They no longer return my calls. I am afraid to use the cruise control.

Service stabilitrak light came on along with abs and traction control and check engine service center found metal debris on tone ring. Unknown origin.

At low speed (under 5 mph) I stepped on the brake pedal and had no response. I stomped down with all my might and still had absolutely no response from either the power antilock nor the manual brake. The car continued forward with no slowing until it hit the car ahead of me, traveling several feet before doing so. I never felt any brake engagement including �pumping� of the antilock or any slowing. I was on a city street and had been at a full or near full stop before letting off the brake to roll forward. I was going straight ahead. Brakes have been regularly serviced.

When approaching a stop and applying the brake pedal, the brake pedal suddenly sinks and car loses traction and the car suddenly feels like it starts to slide. After releasing and then reapplying the brakes, the returns to normal.

Tl the contact owns a 2013 Chevrolet Volt. While driving 55 mph, the brake pedal was applied, but failed to engage. There were no warning indicators illuminated. When the contact shifted into neutral, turned off and restarted the vehicle, it operated normally. The vehicle was taken to allen gwynn Chevrolet (1400 s brand blvd, glendale, CA 91204, (844) 633-8153) where it was diagnosed that the brake pressure modulator valve needed to be replaced. The vehicle was not repaired. The manufacturer was not contacted. The failure mileage was 46,000.

I ran into a vehicle in front of me during normal traffic on my way home from work, two months to the day of picking up my 2018 Volt. The vehicle ahead of me may have stopped quickly, but it was not a stop the Volt shouldn't have been able to handle. I was on a street in my neighborhood I drive every day in traffic. I had mentioned to friends and family that the Volt's brakes just did not feel on par with the rest of the car and would be the only aspect of this ev experience I found lacking. I have the dated text messages to prove this. Now I have a Volt at the body shop for the 5th week (lacking an ac line for reassembly), an over 55% increase in my insurance premiums (per the renewal notice I just received) and what really hasn't been a good experience. While I'm waiting for the return of my Volt I have received the important safety recall indicating the braking performance may be reduced. If the car had been able to stop two feet shorter I'd have an undamaged three month old Volt and my insurance standings untarnished. That two feet ended up costing over $17,500 to the car. Turns out Volts are also expensive to repair. I'm a 55 year old male, no wild kid. Still stuns me that in 2018 gm can't get brakes right. . . The most important of safety systems.

In an emergency braking situation on a city street to avoid a car I hit the brake pedal and it went to the floor, no pulse from the abs system. Hit curb and bumper hit fence. Took car to service to learn abs electronic controller failed. No warning light on dash of any kind. Have learned gm has issued a bulletin but no recall major safety issue. Cost to repair $2400. 00. Car is in perfect condition, has been trouble free and has only 23,000 miles on it.

The stability control system frequently accelerates when braking on a manhole cover or a major pothole. The acceleration is hard and could easily cause the driver to rear-end the car in front. I'm aware of the issue and brake fully before such an obstacle if there is a stopped car in front, but I warn every other person who drives my vehicle because of the seriousness of the issue.

While approaching a red light at 35mph on a smooth road when I pressed my brake pedal nothing happened for nearly a second then the brakes worked as usual. Luckily no one was in front of me or I could of easily been in a crash. The Volt has a brake-by-wire system with regenerative braking. I feel that either the regenerative braking failed and the computer took a long time to revert to the friction brakes or the brake module temporary failed and neither regen or friction brakes were available. I've driven a first year leaf where sometimes there is a slight delay when switching to friction brakes in certain situations, and this event was much much worse than that. Road and weather conditions were perfect that day.

This is the third incident since I had this car along with charging issue in the beginning of ownership this Chevrolet Volt has been been deem total from the accident that occurred on January 6 because of the steering locking up.

The brake pedal and gas pedal both modulate pressure needed to either accelerate or brake. The brake pedal will change pressure needed to brake suddenly, causing you to apply much more force to brake pedal, which is unexpected and dangerous. For example, when driving at highway speed, a car in front of you stops, and you apply brakes. Traffic clears and you release brakes, but then car in front stops again and requires you to brake again suddenly. This time the brake pedal will require more pressure and pedal travel is significantly more. This is unsafe and needs to be changed.

While slowing down approaching a red light with the gear in l (regenerative braking), the car was in electric mode and traveling at a low speed (under 10mph and likely less than 5mph) when the passenger side front tire went into a large but shallow pot hole at which time the car felt like it accelerated (at the very least deceleration ended). My foot was already on the brake pedal (not sure if I was pressing it); however, I immediately mashed the brake pedal down as far as it would go. At first this did not seem to have any effect. After a moment, though, it finally kicked in and the car stopped immediately. I do not believe I hit the car in front of me (which was completely stopped). However, that driver wasn't sure if I did and asked for my information (there was no paint transfer or any marks on my car--there was a mark on the other vehicle which I believe was already there and the other driver wasn't sure and wanted to talk to her husband about it). Note in the later section that asks "was there a crash?" I am marking no as I do not believe there was a collision nor is there any physical evidence on my car of a collision. However, the other driver may dispute that.

On may 13th, approx. 11:10am, clear and sunny 75f redondo beach, CA. I entered the Volt to back out down a downward sloping driveway. I powered my Volt up with foot on brake proceeded to shift the Volt in �r�. As soon as I released pressure on the brake pedal I started to move down the driveway and picking up speed. I applied pressure to the brake pedal,which felt mushy. And my Volt continued picking up speed and would not stop. I continued to apply the brakes, which felt very mushy, and the Volt continued and crossed the street and impacted the residence directly across to finally stop my Volt. The brakes felt extremely mushy extending about � to the floor but not completely to the floor. When this occurred, I was in battery mode but the engine was engaged and running at high rpm and heard by me and a passerby while the Volt was moving. I called aaa to pull me out. I was stuck on the tree and front steps. I called in the incident to my insurance company so I could start the claim and have a claim #. Police arrived 40 minutes later to take a report and give me a field sobriety test. That was a little embarrassing but glad it was done. Now it's documented that I was totally sober. I've read 1-or 2 threads regarding non-operating mushy brakes but nothing about a Volt in r coming down a slope and not being able to stop. I called on-star to see if they have a log of codes generated from my Volt within the last 24 hrs and was told no. I am very grateful that I did not hit another person, animal or vehicle while not being in control of a fast moving Volt crossing sidewalks and a residential street. I have contacted gm allegations and have a claim #. I am supposedly to receive a call by Monday the 19 to discuss next steps. Another thing the 2015 does not have a emergency brake but a parking brake which will not slow the vehicle down in an emergency situation.

Adaptive cruise control unavailable randomly occurs while driving using adaptive cruise control. Presents a large danger of hitting other vehicles if the adaptive cruise control is used to come to a complete stop as it will randomly disengage while coming to a stop. Cruise control only works 4/10 times attempted and was "fixed" by the dealer with less than 500 miles on the odometer. However the problem recurred within a day. Looked it up in forums and it is not an uncommon problem. Holding foot under the brake pedal allows cruise control to work but is more dangerous than randomly cutting off. No one in Volt forum has gotten a complete fix to date. When they do I will be getting mine repaired armed with the correct information. But it is dangerous.

The contact owns a 2012 Chevrolet Volt. The contact stated while driving 40 mph, the brake pedal was applied however, the vehicle failed to stop. The contact was able to maneuver the vehicle and coast to a parking lot. There were no warning lights illuminated. The vehicle was towed to the local dealer to be diagnosed. The contact was informed that the brake module modulator needed to be replaced. The contact stated that the failure was related to NHTSA campaign number 13v271000: (electronic stability control, service brakes). The manufacturer was notified of the failure however, no further assistance was provided. The failure mileage was approximate 84,682.

I suddenly totally lost braking power at a stop sign. Was at about 30mph when I tried to apply brakes. I cross the street at good speed and car finally stops about 100 meters away. Display messages: regenerative braking disable, service your brakes, service stabilitrack. Warning light: abs, stabilitrack and maybe others. I then drive this car very slowly in this condition for 5 km. The brake pedal was up and very firm. At home, I shot off car and plug it. One hour later, it was back in perfectly normal condition, no warning light and no message. Test drive show good brakes. I bring the car to the dealer on Monday. They found one hidden to customer (no check engine) code, c12e6. They follow instruction and replace abs module. They told me that if I get same problem again they will replace abs pump. I argue with no luck that I cannot go away driving a car with possible sudden brake lost issue. I then contacted gm (volt advisor) with no better results. Gm apparently study my case for 3 months. After that, advisor call me and ask if I have lost brakes again. She said since you haven't lost brakes for 3 months, we consider your car to be well fix, case is close. I personnaly believe that the code is not related to the total brake lost. An abs module can not shut off brakes. The electric brake booster may have a design flaw. Nissan had similar problem with the leaf at low temperature, they made a safety recall. Volt and leaf have similar electric brake booster. Temperature was 18 deg f, road was covered with packed snow, traction was fair. I was getting the usual low traction message when applying brakes too hard before the total brake lost event. Volt brake system involve computer in order to blend regenerative braking and friction brakes. The brake booster is electric (no vacum) and computer driven. I happen to be the actual brake engineer for ski-doo snowmobiles!!!.

While the brake pedal is pressed, if one side of the car goes over a pot hole, the car loses braking power and continues forward even though the brake pedal is pressed. For example, if the right front tire goes into a pothole while trying to stop at an oncoming red light, the car displays a message in red letters on the dashboard referencing low traction while simultaneously losing braking power. The car continues forward with no braking power even though I still have my foot on the brake pedal. It only recovers braking power after two seconds. Unfortunately, by then, it might be too late to stop. This has happened twice. This is obviously a dangerous software error with the traction or anti-lock braking system.

While backing up at low speed, my wife applied the brakes and the pedal went to the floor, she lifted her foot and applied the brakes and once again the pedal went to the floor. The car did not slow or stop. The speed was so low that the car came to a stop on its own when there was a small rise. The indicator light said "low traction". This occurred in a private parking lot. The car was backing straight with no steering.

This car relies on regenerative braking when the brakes are first applied. Regenerative braking is only applied to the front wheels. When a wheel loses traction, regen braking switches off completely and immediately, and friction brakes take over. The problem is that there is a delay from regen braking switching off to the friction brakes activating. This delay causes the car's braking distance to increase by a considerable amount, 5-10ft in my perception. This usually happens on wet or snowy roads. The car should really attempt to keep the perceived braking force constant by applying the friction brakes to compensate for the regen switching off and then activate the friction brakes and abs, as needed, to limit wheel lock. This would make the experience a normal abs activation event, which drivers of any modern car should be used to.

I was approaching a sudden red light and applied my brakes hard but not too hard (I did not suddenly slam the brakes). The brakes applied as expected at first but the brakes let up some and my vehicle failed to decelerate for about half a second before the brakes applied again and decelerated to a stop. I was not able to depress the pedal further when it was clear that the brakes were not decelerating.

Tl- the contact owns a 2012 Chevrolet Volt. The contact stated that on several occasions, she heard an abnormal noise coming from the regenerative brake bearing. The contact also stated that while the brake pedal was depressed the vehicle failed to stop. As a result, she had to wait for the brake pedal to return to normal position to stop. No warning lights illuminated. The vehicle was not taken to a dealer. The vehicle was not diagnosed ot repaired. The manufacturer was made aware of the failure. The failure mileage was 62,000. Lt.

The contact owns a 2012 Chevrolet Volt. The contact stated that the brake pedal was applied and did not respond numerous times. The failure occurred intermittently. While driving, the transmission brackets fractured and caused the transmission to become detached. The vehicle was towed to a dealer for inspection and repair. The vehicle was not included in NHTSA campaign number: 13v271000 (electronic stability control, service brakes). The manufacturer was notified of the failure. The approximate failure mileage was 20,000.

Unexpectedly, generally on uneven street/roadway, hilly the brakes do not immediately engage and will create a feeling that you many not be able to stop and/or steer, or keep the vehicle under control. After taking the automobile to a dealer about four times, it was determined July 2014 that brakes needed to be replaced. The car was and still is under warranty. I believe that the braking system is also covered under an extended electric car warranty. Brake problems have continued intermittently; are auto safety issue. The last two times I have not reported to the dealer, or Volt advisor. The dealer service advisor was incorrect about how regenerative brakes work in electric car. The blind spot is excessive for backing up, and every Volt should have had a back up camera as standard equipment, and bumpers that had crash test standards, but was not aware of options when car was sold by dealer sent a few Volts to sell. Aftermarket camera high price, less desirable than factory installed. Tax credit information should have been more clearly provided (including the tax form provided by dealers and bosch's partnership with general motors for 240 Voltec charger). Dealer advertising needed to be accurate and transparent. Due to uninformed. Or politically conservative cpa & broker (2 individuals), did not receive a federal tax credit for purchase of Volt or installation of 240 Volt charging system. I could have easily qualified for the tax credit, which cpa failed to adequately and accurately advise me for tax planning. I have loved the Volt. However, without the anticipated tax credit, past and ongoing braking issues, blind spot problems, large price drop in value of the car (which had similar prices for 2011, 2012, or 2013 models when I bought my car. The tax credit exists to encourage electric cars, not to play a game of "gotcha. ".
