2005 Impala ABS and traction control light comes on. .

your abs is turning on thats whats making the brake pedal push back on your foot. you need to get the trouble codes read somewhere either at a shop or parts store. one you have the code it will point you in the right direction.

I can understand the frustration experienced when lights are on inside the dash. Can you help me understand something; is your ABS light still on in the vehicle or were you questioning the pressure/ push that you were feeling from the pedal? Marlea Wilson, GM Customer Service

The ABS and traction control lights come on. When this happens the brake pedal tries to "push back" against my foot whenever I apply the brakes. This happens about 70-80% of the time when I drive this car. It did this several months ago and I was told by a mechanic that the front hubs needed to be replaced. Both hubs were replaced and the problem went away for a few months but has since returned. Sometimes it sounds like something is slipping in the front wheels and the brakes "vibrate" but this is only under low speed such as in a parking lot.

Go get the dtc's checked. You probably have a wheel speed sensor fault. If you have a light on a dtc has been stored you need a scan tool to figure out what that dtc is

You will need an abs scan tool, auto zones cheap scanner won't pick up the abs code.

I fixed this problem yesterday. Background: My 2005 Impala had the exact same problem; "ABS", "Traction light off", and message "Service Traction System" in the message center. When accelerating or turning from a stop the car it sounds like something is slipping and took off very slowly. The mechanic said the wheel hubs had to be replaced, replaced both front wheel hubs but this didn't solve this issue. I had the Diagnostic Trouble Codes for OBD II checked and nothing came up. Solution: I went to the Autozone and asked for them to use their ABS code reader, (also free of charge but different from their DTC code reader). They read this and found 5 codes: C1216: EBCM Command Pressure Release Is Too Long C1221: LF Wheel Speed Sensor Input Signal is 0 C1225: LF Excessive Wheel Speed Variation C1232: Left Front Wheel Speed Sensor Circuit Open Or Shorted C1245: Low Tire Pressure Detected Problem solving: From this I knew one of two things could be wrong, the speed sensor in the wheel hub could be bad or their could be a problem with the speed sensor cable. How I solved my car's issue: I put the car on a jack stand and removed the front left tire. It turned out that the speed sensor on the wheel hub was unplugged. Weird right? Well the plastic cable housing has plastic strain reliefs (in circular shapes) that hold the wire onto the chasis so that the cable doesn't move around or get caught in the tire or drag on the ground. This strain relief was somehow set up so that the cable for the speed sensor did not have enough slack. When you turned the wheel all the way, the cable would unplug itself. I un-did all of the strain reliefs, put the cable in a position with more slack on the wheel hub speed sensor connector, and put it back into all of the strain reliefs. I drove it yesterday and today and the problem is gone. Your problem could be in any of the wheel hub speed sensor circuits. I would recommend going to an Autozone and asking for their free ABS reader diagnostic to find out which tire's circuit is the problem. From here it could be the wheel hub speed sensor or the cable to it. If it is the wheel hub speed sensor, you may have to replace the wheel hub itself. But if it is a cable problem (more common) you may have to replace the cable. (Or maybe you are lucky and like mine it was just unplugged.) There is a way to check the cable using a multimeter and continuity. If it's not the cable it's the sensor. There are a lot of youtube videos about changing speed sensors and wheel hub assemblies or speed sensor cables. Hope this helps. Scott Burke, Richmond, KY

This information was very helpful. I also had both Hub assembly replaced, and all the same lights came on intermittently, I felt brake pedal pushing back at me, same with turning slow, or driving at slow speed, and always in a parking lot. This happen for me after I was hit on my passenger fender. I have been to the mechanic three times and all I do is pay for replacing parts. No one has the answer. I am going to auto zone after work to night for the ABS reader diagnostic. I really appreciate everyone's input. I felt so alone on this problem before finding this page .

This is happening to me. 2005 Chevy Impala. Replaced both front hubs and sensors a few months ago. I will go to auto zone this weekend. Hopefully I can get this resolved. It's becoming one thing after another with this car. Starting to get fed up. But I love the car. I have a love/hate relationship with my car. Wish me luck. Julie Iowa

we should call to make it a recall, because this is crazy and it can be dangerous, i just wonder how many people have this issue, supposely its a $600 fix maybe more in a different location, but damn this is crazy i dont even drive my car like a race car for me to have this issue

scottgnd...did it seem like there was a clunking in the front end when you turned the wheel? I am having the service traction control light come on and the trac off light and abs light.

Has anyone found the solution? I have a 2007 impala with some of the same problems. Sometimes when I go from a stop my traction control kicks on. When this happens my car hesitates to go (I'm afraid I'm going to get hit one of these days) and makes a noise. Sometimes it kicks on the ABS and service brake lights. I have taken it to 2 different mechanics that they say it's the sensor. I have had my wheel hub replaced THREE times and is still doing it. Both mechanics say the connectors are fine. I'm getting frustrated!!

tril2021 I never had a clunking sound. Just a hesitation to go. Jenbem, the problem came back after about a year of simply plugging in the unplugged connector on my wheel hub assembly. Orielly hooked up the ABS code reader and told me that there is erratic data coming from my front left wheel hub sensor. On the 2005 Impala this is built in and the whole wheel hub assembly has to be replaced. I have yet to replace it but plan too. I will let you all know if this solves it for me. After reading Jenbem's comment I am less hopeful.

2005 Chevy Impala, "ABS, TRACTION OFF", Message Lights was "ALWAYS" Intermittently. Car was scanned multiple times using ABS code reader, and other scanning devices, but nothing, meaning no trouble codes. Used (3) well known auto repair shops, and ended up replacing both front hubs three times. Kept a careful watch on the tire pressure, no issues with speed sensors in the hubs because I had replaced both front hubs three times on recommendations from all three auto repair shops, the speed sensor cables were never unplugged. For 18 months, I had experienced brake pedal pushing back against my foot, vibrating and making awful noise when driving at a low speed and making turns. Happened more frequently when driving in parking lots. When visiting with an old friend from high school who collects cars and does his own repairs decided to take a look. He didn't use a floor jack, I was asked to cranked the wheel by turning it all the way. Some wires were bad. He replaced the anti-lock brake sensor harness. The part cost $37.99 at Advance Auto Parts in Texas. I know if you are not lucky tot know someone who works on cars, the auto repair shop charge a heft price for the part, but the fee for the labor should be cheap. Estimate time is 30 minutes. My friend had the new anti-lock brake sensor harness on my car within 15 minutes, and "Yes", I did the time because we were in the Advance Auto Parts parking lot. "Problem Solved"

If all else fails and the problem becomes too expensive for an older car, just unplug the ABS fuse. I am a retired auto mechanic and sometimes it becomes a nightmare and spend too much money to solve an ABS problem on an older vehicle. I realize this is a last ditch resort, but it works. I am not a fan of ABS anyway. I would rather pump the brakes when I need to manually. Dennis

I have had the same issue with my 2009 chevy impala. I've replaced the accelerator pad, both wheel hubs/ the cv axle on the driver side and just recently replaced the caliper as well on the driver side. I will try the anti lock brake sensor harness. I really hope this works as I've about had it.

I have ran into the same problem... Now here is something to think about. All my abs and Trac control lights are on and service Trac system in message center. I always use my cruise control. Drove from NH to RI and all thru NH and MA the lights are on. I get to RI and the lights go off. I didnt use my cruise control in city of Providence. The lights do not come back on. I turn the Cruise control back on, set speed and cancel with brake pedal and the lights come back on. I also read on the brake light sensor could be tripping the abs and Trac Cont. You may call me crazy but I am looking into the Cruise System. Just think I have saved myself a good 100-130 cause I do all the work myself. It gets -20 here as we speak so that could be messing with the system as well. Marcus; NH 05 Impala

thanks that was very helpfull

I am having this same problem, my question is, is it safe to drive the car without fixing the issue? I can't afford a $400 repair, that's my total monthly income.

I am having all of the ABS lights, Trac System Problems and clunking front end when I’m pulling in or out of a parking space with a 2014 Impala. The problem has been carried into the next generation. My car only has 53,000 on it and I have a tire pressure issue and just last night I get a message when I’m in reverse that I have no back up sensors. The heat/ac fan has been a real problem too. I can’t afford to put a lot of money into it right now and I’m super frustrated with all of f these problems. Thank you for all of the helpful advice on this site, gives me a good idea how to talk to the mechanic when I can finally afford to take it in. Thank you for sharing your knowledge.

I have an 08 Chevy Impala SS and I have been having hesitation and a grinding noise when taking off from a full stop. This doesn't happen every time only once in a while. It has been getting worse and worse. I had an alignment and my traction control light went off for a couple months now that is back on and two tire pressure sensors are bad. Just yesterday I heard the grinding noise and the ABS light came on. I never know when the hesitation will happen so I am scared to pull out close to other cars coming. I have had a front axle changed twice in the past year and the clunking noise is returning already and the last time it was replaced was in March of this year. Why is my car hesitating and grinding only sometimes?

05 impalas are trash.
