Brake Sensor Problems of Chevrolet Impala

Stabiltrak abs traction control warning lights all come on vehicle shudders and power is reduced. Researched and found 100's of reports of the same issue with the Impala and similar complaints in the light truck and SUV models. Fix is relatively inexpensive if your mechanically / electrically inclined as involves splicing in a new wire harness for the abs sensor. Said harness is about $20 it shorts out due to insufficient gauge of wire used on original factory install. Replace harness has much sturdier gauge from what my research says. Repair shop quoted $700 to repair glad I told them to put it back together. They have a fleet of Impalas as loaners so they know they are gouging people when they say replace wheel hub assembly abs sensor and wiring harness when they know it's the abs sensor period. Chevy needs to do a recall. Issue happens when car is in motion after turning or going over a bump wiring that has been wore thru due to placement of wiring in a high friction area, wire wears through coating exposes wiring that shorts out and sends codes to computer concerning abs stabiltrak and traction assist causes vehicle to behave erratically others have reported caused vehicle to stall and not restart until problem corrected. I'm sure they are gouged for a thousand $ or more. Wet road conditions,extreme heat or cold,left turn while backing, jarring bumps, all trigger the dash to light up like christmas tree dinging alarm goes off steering shudders power is reduced. It's a huge distraction and safety concern for so many to be experiencing gm should stand up and take care of the problem.

Get abs, traction control, stable stability sensors on. In motion and when sitting still. Resets but comes right back on.

Since 2017, upon starting my car I get all of the following alert msgs "service stabilitrak", *service brake assist" and "service traction control" on my dashboard. I've had the car into les schwab and error code diagnostics done both before and after both front hub assemblies were replaced. The same service messages still continue to appear on the dash. Les schwab has checked the hub sensor wires repeatedly and all error codes and find them to be ok. They find the car to still have a crunching noise coming from the front end of the car, most markedly when turning the wheel to the left, but can also be heard when there is a drop in elevation, as when existing a parking lot into a slightly lower roadway. On June 14,2019, while the car was in motion and turning right at a stoplight, the same situation occurred as has when I make a left turn. The car suddenly acted as though the brakes were being applied very hard and then the car halted briefly with traffic behind me as though it would stall out. I applied the accelerator till I forced the car to move around the corner and after about a minute of fighting braking resistance, I was able to regain normal 40 mph speed with the flow of traffic. This occurred on dry pavement with no precipitation. Outside temperature was around 100 degrees. Best driving conditions with no rough roadway. Les schwab said the problem with the hub sensor and left turning is a known problem to them and said they wish it would be made a recall item as it is a common problem now. I don't feel safe driving this chevy Impala. Love my car but won't take a chance on purchasing same make and model. I wasn't so surprised when researching these issues on the internet to find huge number of owner's having the same problems.

January 2019 was driving on a very congested interstate 95 at the posted speed limit of 65. A warning popped up on my dash board. Service stabil trak engine in reduced power. It was like I longer controlled my car. The speed suddenly dropped. I went from 65mph to maybe 30mph. It felt like my brakes were being applied . I became scared and almost started to panic. But because I was in the far right lane I was able to pull off the interstate. I sat there on the side of the interstate with my heart racing and my hands locked on the steering wheel so hard they cramped up. I turned off my car and removed the keys from the ignition. I thanked god I was alone in that car. I thanked god the car behind me was not tailgating me. I waited for about 5 minutes and then put the key back in the ignition and started the car up. The warning was gone but the service engine light remained on. I was scared to death to merge back onto the interstate so I put on my flashers and drove on the shoulder at 20-30mph until I got to the first exit. I made it home. I called a car repair company. They told me the sensor more than likely need to be reset. They suggested I take it to a chevy dealership service center. The next day I started my car up and all warning were gone so I did not take it to the service center. The car ran fine until today 52/20/2019. I just filled my tank up with gas. Turned it on put it in gear and drove 20feet when the same error came on . I had looked up this error on the internet. Seems lots of americans have almost been killed because a car maker has a mechanism built in to it vehicle that takes control of the speed to which the vehicle is traveling. People are spending a lot money to fix an issue that seems to not have a fix. Chevrolet is putting the lives and the lives of others on the roads in jeopardy with their stabil trak computer sensors. Your failing americans.

Service stabilitrak came on when merging on to the freeway, (which involved a turn to get on the on-ramp,) shutting down the car completely. Almost hit by a semi. I have had the bearings replaced because of stabilitrak light. How has this not been recalled? my friend and I almost died because of the faulty sensors or whatever it is with these crap bearings. I was told how the bearings are made with the sensors being placed in a completely ridiculous spot by auto parts stores. Saw plenty of complaints online with this vehicle. Same issue. How has nothing been done with this?.

Car gets service stabitrack, traction control and abs warning on dash. Replacing wheel hubs with sensors does not fix this issue. Sometimes the car will want to apply brakes while driving or reduce engine speed. I have been through many forums with people reporting the same issue on the same car and through multiple years of manufacturing. From the research I have done in the last few days it looks like hundreds of owners have reported this issue but Chevrolet is not doing anything to correct it. Not sure at this point if it is the wiring harness causing the problem or if this could be something with the computer that controls the stabitrack, abs and traction control. If cars are loosing power and or the brakes are being applied with out driver control this can lead to dangerous driving conditions for the car owner passengers and everyone else driving on the same road. With how many people are reporting this I do not see why the car owner should need to pay thousands of dollars to diagnose and maybe fix the issue. From what I have read some people have had to pay for multiple service events and the issue still not resolved.

Takata recall: shuts off on it's own while driving with loss of control. Loss of steering. Loss of brakes, car shakes. Headlights dim when signaling for turns. Car began shaking with loss of control, battery, ab, and other sensor lights remain on. Odometer became exempt 2016, but seller, cache valley auto sales, lewiston, ut has odometer at 142,221 miles. The seller refuses to fix, or exchange for this vehicle for another vehicle.

My car started having the traction control come on about 2-3 years ago. I was told I needed a new transmission. The transmission was cracked-Chevrolet said not their fault, so, I replaced the transmission. Then, it started doing it again. I replaced the brake pads. It stopped. Then, started up again. Took to the Chevrolet garage who put it on their total diagnostic machine. Told I need both bearings on the front. At a $972. 00 price tag for this, I bought the bearings and had another garage put them on at a great reduction in cost to me on labor. Now, it is doing it again. At first it was only every once in awhile. The wheel sensors appear to be fine. Now I notice it is doing it a lot more and starting to do it when I accelerate from a stop at certain times. I bought this car brand new, and, for its age, it does not even have 60,000 miles on it. (the date that that I am using in the next step here it began is the date when it really started doing its 'tricks' a lot more).

Automatic transmission slipping gears on take off, wheels sound like bearings are going out, like a grinding noise. Changed the front brake pads and rotors together due to wheel wobble and brake sensors on display. Constantly displaying "service traction control" on message board. Dealership has refused to assist with this issue as well as any failures of the vehicle. Vehicle now is immobilized, and will not go into a forward movement only a reverse drive. Wheels are locked up and vehicle is stranded! still making payments on this used purchase. Please advise!!!.

The contact owns a 2012 Chevrolet Impala. While attempting to accelerate the vehicle from a low speed, the accelerator pedal was depressed and the vehicle jerked when the brakes were independently applied. In addition, the abs, service traction control, service stability control, and multiple warning lights illuminated. The failure recurred on numerous occasions. The vehicle was taken to a dealer where it was diagnosed that the wires connected to the sensors were faulty. The technician also stated that further diagnostic testing would be needed to determine what specific part needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 26,000.

Tl- the contact owns a 2008 Chevrolet Impala. The contact stated that while driving at 30 mph, the check engine warning light illuminated before the vehicle jerked severely. In addition, the brakes were unresponsive. The contact pulled over to restart the vehicle but the failure recurred. The contact mentioned reconnecting a vacuum hose after observing that it was disconnected from the power booster. The brakes became responsive. The vehicle was taken to the dealer where it was diagnosed that throttle position sensor had failed and needed to be replaced. The vehicle was repaired but the failure recurred. The vehicle was taken to the dealer once more and was diagnosed that the catalytic converter had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 81,000. Jo.

First my service abs traction control lights came on and while making left turns a loud metal grinding noise happened and my traction control light flashed. I took it to my local mechanic he replaced the bearing and sensors which helped with the service lights but the grinding still happened. The noise and traction control light still continued while turning just not as much as before. The mechanic replaced the part twice!! took it to my mechanic again because of the grinding and traction control flashing he drove it around and he could not make the noise happen so he could not fix or replace anything. It feels like the abs is braking on its own for no reason while I drive my 2013 Impala ltz. My mechanics can not find the problem and it seems neither can any Impala owner or mechanic. But I'm 99% sure when I drive it tonight to visit friends I will hear a metal on metal grinding noise I just hope not while im on the freeway where I can get killed. It happens while driving coming from a stop or as simple as me backing out of my driveway.

The car ignition suddenly shut off and the power steering and brakes failed on a steep grade. (the ignition recall had previously been performed on the vehicle, and the key fob had been reworked so it shouldn't have been a ignition issue). The transmission was shifted into neutral and the car restarted (while still coasting down the hill) to regain control,this was repeated numerous times until a safe place to pull off was reached. This grade was extremely steep, the road had switchbacks , cliffs,and no guardrail, it was a miracle no one was injured or killed. This same vehicle had just had a duplicate problem and was repaired at the dealership in July, less that 1000 miles prior to this current event. The dealer in July replaced the mas sensor and the battery as they said the mas was corroded and needed to be replaced. This current event was caused by the map sensor and the main computer according to the dealer.

I was heading to work I slowed to turn right on to the on ramp of the interstate, as I began my turn I lost all power the vehicle shut off, lights went dead and the brakes went out. I made it to the curb and vehicle would not restart. Vehicle had to be towed home. I have checked all that could have caused the issue and have narrowed it down to the ignition switch, battery has been replaced even though it checked fine. Starter is brand new. Mass air sensor checks ok and cam and crank sensors check ok. I was lucky if I had been on the interstate I would have had no chance to recover from this failure. Even though this vehicle is 14 years old this type of failure should not have happened. I have never carried more than the ignition key and key fob on the key ring as both my wife and I use the vehicle.

Tl- the contact owns a 2010 Chevrolet Impala. The contact stated that the vehicle stalled several times and when applying force to the brake pedal it went to the floor and did not stop the vehicle on numerous occasions. The contact constantly saw the sensor for the abs illuminate and the air bag is off light intermittently. The contact inidicated that while traveling 60 mph, force was applied to the brake pedal and it did not stop the vehicle causing the contact to crash into the rear of another vehicle. The air bags did not deploy. The contact was not injured. A police report was filed. The insurance adjustor had the body damages to the vehicle repaired by an independent repair shop, however the failure continued to recurr with the brake pedal and the air bag sensor showed off when the crash occured. The contact was later notified of NHTSA campaign id number: 14v355000 (electrical system ) and was waiting for parts to get the vehicle repaired. The vehicle was not diagnosed nor repaired by the authorized dealer and the contact was waiting for the parts and approval from the manufacturer to remedy the recall. The contact was told parts were not available by one dealer and another dealer indicated that they would repair the vehicle without parts. The manufacturer was notified of the failure. The approximate failure mileage was 70,000. Dyd.

The contact owns a 2003 Chevrolet Impala. While attempting to accelerate from a stop, the traction and brake warning indicators illuminated. The contact stated that the vehicle jerked during acceleration. The failure occurred on a daily basis. The dealer stated that the hub sensor needed to be replaced. The vehicle was repaired and the failure recurred three days later. The manufacturer was not notified. The failure mileage was 80,300.

When I was driving my vehicle a couple months back my car only steer one way and I had to stop on side of the road so I went to the shop and they told me ot was my rack and pinion so he repair that after a few weeks of driving ot my rack started leaking again now im stuck with that not to mention I replace my 02 shift sensor and I suppose to stop my car for stall in firest and second gear but it still do d the same and now it go n to gear and won't move.

Steering spills oil and hard to turn rear brake tire pressure sensor is on.

At 55 mph on a slippery right hand side curve (speed limit is 65 mph) vehicle under-steered and lost traction completely, without touching the brakes, it started to slow down and skidded to the outside of the curve (to the left). I tried to get it back to the driving lane, it started to skid laterally to the right and slowed down until it hit a reflector post on the edge of the right lane and stopped. Vehicle information on the dash board read "ice detected. . . ". Although the damage on the right door was a very minor dent, the car deployed all 4 head curtain airbags and 2 right side airbags, engine was shut down and front seat-belts were stuck. Few minutes later, the engine ran normally with the "ice detected . . " message still on. It seems that the airbags sensors were activated for no required reason for a minor dent on the door. Also, the stability and the faulty braking system might be of a great safety issue on this vehicle.

At first it was when backing up and turning sharp. The traction control message would come on and a grinding like sound from the front driver wheel area. Later it included the abs warning and would also occur after backing with turn and going forward at that moment. Now randomly when pulling out and the service air bag light comes on. Recently also the oil pressure low message and dummy light come on 3-4 times before stopping (and yes the oil pressure is good with correct oil, tires, pressure, brakes, sensors all check good). Best guess diagnostics is shorting in wiring harness that can not be located until it fails completely. However with grabbing with traction control when pulling out and air bag problems it is obvious this is a safety hazard.

The contact leased a 2014 Chevrolet Impala. While driving approximately 70 mph with the cruise control engaged, the front crash sensor warning indicator illuminated as the brakes independently depressed. The contact depressed the accelerator pedal, which disengaged the brakes. The failure recurred on several occasions. The vehicle was taken to the dealer but the failure was unable to be determined. The vehicle was not repaired. The contact also stated that while the vehicle was parked with the keys out of the ignition, the radio, the light behind the control buttons on the steering wheel, and the lights behind the display for the radio illuminated; however, there was nothing displayed on the screen for the radio. The failure recurred on several occasions. The manufacturer was made aware of the failure. The approximate failure mileage was 100.

About 2 weeks ago my service traction control light appeared on the dash. Being the person that I am I was very concerned with this issue and took it to have it checked by the dealership. They told me that this will occasionally come on with the amount of rain we had in our area. They said when it has the opportunity to dry out it will go off. Well to date it has not gone off but stays on the majority of the time. Now it is having fun with the reduce power light which basically slows down the car. Not only are the flip flopping but when I push the brakes it sometimes acts as if it will catch but then let go and catch again. How scary is this when you feel your brakes will not stop the car? this is not a good feeling. Called the dealership to get an appointment and it will cost me $85 to $100 to have this put on a machine to see what the problem is. And get this just like everyone else this is not a covered problem. My question is why? I have tried very hard to stick with Chevrolet products but this is really making me rethink my decision. Everyone seems to be having the same issues with these alerts and sensors. I am not one to sink a whole lot of money into a car with repairs, I will get rid of it immediately. I maintain my car on a regular basis.

The first instance I was driving and the "service brake system" flashed on the display. I had all brake pads replaced at dealer on 1/3/2013. 2/7/2013 I was in traffic and the car suddenly slows to about 10 mph and would not accelerate the dash then displayed "reduced engine power" and the check engine light came on. On 2/14/2013, I had the throttle positioning sensor replaced and at the same time had the rear defrost wiring repaired because that had not been working for over a year. On 3/4/2013 the car would not start by the factory remote start, so went out and started the car with the key, when I returned to the car the vehicle would not start at all the chime would sound the lights on the dash flashed but no start. I waited a few minutes then tried again, the car started briefly (50 seconds) "reduced engine power" appeared on the dash then it shut down completely. I looked under the hood saw the battery attachment was loose, tightened that up and then the car started up. However, the car radio (factory radio never replaced), the chime, or the ticking of the turning signals no longer work. I have an appointment with dealer on 3/14/13, but the car seems to be failing all around. In reading chevy/gm forums, there are thousands of chevy owners experiencing these same issues, chevy/gm needs to take ownership and investigate these vehicles to determine the root cause of the problems. Nearly 3000 dollars later in dealer repairs is not getting to the bottom of the issue. I was nearly in a crash due to the reduced engine power issue and that was scary enough to make me not want to drive this car or an at all.

I noticed some time back that when applying the brakes that I would get a rough vibration, such as with bad rotors. I took the car to the dealer that I purchased it at and they looked it over and stated that everything was fine. Since then everytime I hit the brakes the vibrations have only gotten worse, it's to the point now that it violently shakes the entire car and feels as if it's going to jerk the steering wheel right out of my hands. So I made another appointment for this issue and a new one; sometimes my dash lights will flicker and it will tell me it's 102 outside when it's only 70 and automatic tire pressure sensor is way, way off. I have also noticed recently that my front tires have become excessively worn on the outer edges to where there is only tread in the center and this shouldn't be a problem with only 21,500 miles on the vehicle; I should have been able to get about twice that out of the factory tires. At my last appointment they have still said there is no notable problems with my Impala.

My abs and traction control lights came on I was told it was my bearings. I replaced those and problems began again I was told it was my brakes and rotors and replaced those. Problem began again I was told it was my sensors, again I replaced those. Problem began again I was told it has to be the senor, another repair. All the while constantly needing tires (pressure lights also kept coming on) well abs and traction control problem began again. I backed up and car wouldn't go forward. It'll go forward in 1 n 2 I believe. Help!. .

While driving in rain, the warning light for the traction control system came on showing it was "off" and pressing the reset button would not make it come back on. One of the rear sensors had failed, disabling the traction control and antilock systems.

Left rear wheel sensor failed in wet weather, disabling the traction control system and the anti-lock brake system on the vehicle. Same component failed on right rear several thousand miles earlier, in January of 2007. Very expensive part to replace ($378. 00) in each case, plus labor.

The anti-lock braking system would engage when the brake pedal was depressed at low to moderate speeds. This occurred on dry pavement and seemed to extend the length of time needed to come to a complete stop. The dealership replaced the hub and sensor. The problem recurred. The hub and sensor were adjusted. The problem recurred. The dealership had to replace the wiring harness to correct the problem. Old parts were never offered in return. The repair was not covered by warranty.

Bought vehicle in April, 2002. We have had repeated malfunctions of the traction control system. I have uploaded a few of the repair documents we had collected over the years. I have several more. Despite numerous repairs, from wheel sensors, to wiring (including complete harness), computer chips, resets, etc. Every attempt by chevy to fix this poorly designed system have failed. Chevy has admitted they don't know what to do. Their best suggestion is to try yet another dealership. I am tired of wasting my money on a poorly designed and installed safety feature. The system has failed on start up, driving at highway speeds, low speeds, while braking, etc. I have contacted gm corporate twice. Once they replaced the wiring harness only to have it fail shortly after. My second contact is in progress. My online searches of this year and model have revealed many such complaints on this model and similar models. The story is the same: gm can't fix the problem. We live in snow country, and traction control is important to us. Currently the system has been out of service for over two years. If you investigate this issue on this year and model, you will find this is a common problem that gm has not recalled. Please investigate. Thank you.

We bought this 2002 Chevrolet Impala in April of 2002. Fortunately, we purchased the extended warranty. We have had continuous problems with the traction control system. Initially, the warranty covered the malfunctions: wheel sensors, modules, brake pump, wiring, etc. Were replaced. Shortly after each repair, the system failed again. When the warranty expired we continued to experience system malfunctions, replacing part after part. To date, over $3. 5k has been spent to attempt to fix this poorly designed and installed system. It has been out of service for more years, than it has functioned. It has been out for the last 3 years, because we can not put good money after bad. I recently contacted gm corporate with my complaint and they told me to take it in for system diagnosis. Same result: brake pump and module out, with possible wiring problems and wheel sensors. Estimate to try to fix: $2. 5k. No gurantee it will work. This malfunction occurs with no warning: sometimes upon starting the vehicle, while driving or turning. I investigated this problem online and found many others have experienced similar problems, not being able to get them fixed properly. It occurs in Impalas and monte carlos of similar years, 2002-2008. How can gm justify spending $6k to maintain a single system which works directly with the abs brake system? my contact at gm is danielle 855. 880. 1500 ext. 5921509. Chevrolet needs to do a recall on this faulty, poorly engineered system. Please investigate. Thank you. (I have attached just a few of the many invoices I have collected over the years for your inspection. ).
