Chevrolet Corvette adaptive cruise problems

Filed May 13, 2021 · Acceleration, Brakes · 51,000 miles · NY

My corvette as well as many others from 97-04 suffer from the active handling ABS/traction control system going bad. The part is known as the ebcm. When it goes bad (if cruise is engaged) the car will disable cruise control suddenly causing car to slow down. Also, when the system fails while moving it cause cause uneven brake feeling and you loose the ABS and traction control systems . Gm has discontinued the parts required to repair this and this issue has been major safety concerns for many years now affecting many 97-04 corvettes. Also a part of this system is the steeling wheel position sensor which is also discontinued. Swps can send wrong info to the other computers and the car will make erroneous 'corrections' that can lead to brakes being applied at any moment while driving.

Known issues with a sub standard torgue coverter causing a shudder and jerky motion the car starts demonstrating accompanied by fluctuating engine rpms. This corvette is equipped with a 8i90 8 speed automatic transmission. Its especially noticeable when cruising at highway speed with the cruise control engaged, however it displays this problem whether the cruise control is engaged or not. This issue seems to have affected about 20,000 corvettes until about the end of october 2016 production dates. Internet research shows tha this is a wide spread problem and there should be a recall on these vehicles that requires gm to replaces the transmission and torque converter

Brake issue: brakes would stay on until pressed. Cruise control would also not function while the brake lights were engaged. Pressing the brakes would cause the brake lights to turn off. Taking foot off brakes would cause brake lights to turn on. Repaired by chevrolet for $450. Electrical: starter has been replaced 11 times by firestone & chevrolet. Starter repeatedly stops working after 6 months of use (using original oem parts installed at full price by chevrolet).

Causes the brake lights to illuminate without the brake pedal being pushed; the brake lights to not illuminate when the pedal is pushed; difficulty disengaging the cruise control; moving the gear shifter out of the 'park' position without pushing the brake; and disablement of crash avoidance features such as traction control, electronic stability control, and panic braking assist features

This is a recurring but intermittent problem with the exact same symptoms as described for non-corvette gm models in the federal safety agency campaign number: 14v252000 "the brake lights to illuminate without the brake pedal being pushed; the brake lights to not illuminate when the pedal is pushed; difficulty disengaging the cruise control; moving the gear shifter out of the 'park' position without pushing the brake; and disablement of crash avoidance features such as traction control, electronic stability control, and panic braking assist features." I have noticed that the problem often initiates when driving over a bump, suggesting an intermittent open or short wiring issue. Then later things will return to normal for days or weeks. Chevy dealer first recalibrated the "brake pedal position sensor" then later replaced and recalibrated it; both non-warranty repairs. The problem continues with the next recommended action to replace the bcm at $700+ cost.

I and other corvette owners are having the same issue as the most recent recall of other gm models. My brake lights will constantly be on. The active handling warning light will continue to show on dash and cruise control will disengaged and reengage on its own. The fix seems to be replacing the body control module. I have replaced the brake sensor and that did not fix the issue. After reading blogs I located other corvette owners experiencing the same issues as I.

My car has spent weeks at autonation chevrolet in alpharetta, ga until I took it back from them and brought it to a corvette dealer in atlanta, ga to replace the bcm and hope to fix the issue for now.

Traveling at 65 MPH with the cruise control on driving on a straight 4 lane divided highway, I brake and pressed the clutch pedal to down shift to make an exit. I exited, made the turn and started accelerating. I notice a loss of power and the steering wheel shook. There was no message that the active handling was engaged. I stopped and turned off the engine. All was fine when I drove again. However, it keeps happening sporadically without any cause. Once the service active handling system lit on the control panel but after turning off the engine it has not appeared again. Yet, the active handling system(or something) keep tapping the brakes making the car lose power and the steering shake.

2004 chevrolet corvette. Consumer writes in regards to malfunction of cruise and traction controls. *smd the consumer stated over the past two months the cruise control would shut off automatically. He would turn it back on and it would work for a very short time and then shut off again. In addition, while driving at a high speeds of 65-70, the consumer felt a slight slow down in the engine and a pull to the right in the steering. Once he turned off the traction control, the problem ceased.
