2015 CHEVROLET IMPALA Lane Departure Problems

Side Blind Zone Alert (SZBA) system continues to be an issue with this vehicle. Sensing module(s) on inner left or right side of bumper cover fail due to water intrusion. When sensing module fails, "Service Side Detection System" message will appear on driver information center on instrument cluster. General Motors has previously issued a special coverage "N172097060", which is available on NHTSA website. As indicated in the special coverage document, if the issue is ignored, "the condition could result in the corruption of LS GMLAN that may result in the loss of some driver interface functions such as cluster, infotainment, displays, chime, and passenger presence detection (passenger airbag could be suppressed). Within approximately 30 days of the "Service Side Detection System" message, while driving, instrument cluster speedometer and tachometer went dead, and airbag warning system notification, anti-theft system, tire pressure monitoring system all illuminated. In addition to no speedometer reading, vehicle ignition/security interlock was causing vehicle to run rough. Vehicle would not immediately restart after shutting vehicle off. This is the 4th time a SBZA sensing module has failed on this vehicle. First failure was replaced under factory warranty, second failure was replaced under special coverage N172097060, third failure was replaced out-of-pocket. Contacted General Motors/Chevrolet, and they are not interested in providing continued coverage of the issue, which is a known issue, and likely a design defect, as the design was changed for later model years.

GM has a know issue with the side detection system and refuses to do anything about it even after there service bulletin expired. When this fail it can cause other issues with the dashboard system failure and more. In this case the system would never shutdown draining the battery.

The blind spot warning system stopped working, and yes it is available for inspection upon request. I have heard this leads to further electrical problems and am worried this may compromise my safety if not dealt with. The problem has not been confirmed by a dealer. The component has not been inspected. There was a warning that popped up stating “service side detection system” that appeared randomly on my drive home the other day. I had not hit anything or done anything to the car that might have caused this.

The Side Detection System failed. Both rare modules are shorted. The defective module drain out the battery, causing engine start failure. And the defective module may cause fire. I have one side of the modules repaired in three years ago. Now both sides are failed. I had two jump start in the recent month. Every time I start the engine, warning for service of Side Detection System shows up.

In April 2019, the side detection module was replaced under warranty, at 21,500 miles. The same ‘issues’ are reappearing, where a warning is illuminated on the side mirror when no cars are present. If the dealer/ mfr replaced the original modules and wiring harness with the same items, this would only delay a reoccurrence. I called Chevy Cust. Sec for assistance, and they said their ‘recall’ program expired in 2019. The car currently has just 47,000 miles and the the modules should not have failed a second time. There is obviously a design flaw, allowing water penetration, and Chevy did nothing to prevent it.

This system failed causing the cars computer to go haywire. I lost my speedometer and total dash display while driving.

Side Blind Zone Alert Module, Service Side Detection System

Have had issues 2 times since owning this vehicle, both times sensor was replaced by dealership. Was told by service at dealership that this is a known issue for GM. Dealership found side detection modules swelled and connections corroded. Again for the 3rd time since owning this car from new. They, the dealership, cost the replacement of the module at $980.00 including labor. To fix an issue they have known about for years

I have had the blind spot modules replaced two times already and they are out for the third time. I have had to replace them like just over every 2 years. This time I had loan my car to my daughter, due to any accident she had with a deer, and had her four kids in the car when multiple modules started shutting down and nearly leaving her stranded. When I was able to inspect the car i found the the blind spot modules where extremally corroded and showed signs of melting to almost catching fire. I believe that these are a safety issue, and need to be recalled and problem fixed with a reliably solution. I am a ASE Certified Master Technician and have been for well over 38 years. and have seen many of these GM modules go bad multicable times.

My dealer is charging me $1606 for 2 sidevew detection modules caused by water damage and corrosion and that’s not covered under my extended warranty for my 2015 Chevy impala ltz 108k miles my cars has trouble starting and I have no working dash indicators no speed no gas no temp no rpm’s air bag light on and trac control on light . No turn indicators and no heat or ac and key fob don’t work unless I insert key fob arm rest slot all because of the sideveiw modules wow that is mind blowing $453 to diagnose and $1606 to fix

System failed suddenly stabilitrac , abs power steering, side detection all flashed on dash . Had to replace computer to restore power steering and stabilitrac and abs . Side detection a safety item still inoperative.

Service side detection notice came on, after replacing twice. While driving on the highway my speedometer dropped to zero. My odometer stopped advancing. My blinkers stopped working, as did my radio. Speedometer went to 12 (while driving at highway speeds) stayed at 12.

My side detection system has failed and not working on my 2015 ltz. Blind spot light stays on even when car is off. It’s causing other lights going crazy on and off. No check engine light on just the side blind spot indicator lights stay on. My car only has 70k miles it’s been happening for 1 wk I’m afraid to drive it after reading online that a clients impala nearly caught on fire. I’m reading that there is a recall with 2015 impala # n172097060 side blind zone alert module water intrusion. Please advise if there is anything Chevy/GM can do for me. I’m afraid to drive car and feel it’s a hazard driving around with faulty blind spots light.

Side detection system is failed. Used for blind spots and I know this can cause more issues with car.

Taillight gasket failed and leaks water resulting in water leaking into trunk anytime it rains or go through car wash. This caused corrosion to the amplifier shorting it out, there is now no sound or on star available. It also caused the blind spot detection monitor to have issues and no longer work. Upon inspection when the vehicle is running the wires sometimes start smoking white. Dealer said there was no issue, obviously the radio doesn’t work, the screen doesn’t even light up, no backup camera, no sound warning if the forward collision system is engaged, no seatbelt ding, no blinker sounds, no rear detection system or cross traffic warning system.

WE ARE STILL HAVING ISSUES WITH THIS STUPID SBZA BLIND SPOT DETECTION SYSTEM, TWICE NOW, FIRST TIME WE HAD FIXED, 2.5 YRS AGO NOW, AT A $1000 COST TO US, AS MILEAGE WAS SLIGHTLY OVER THE QUALIFYING MILES WITH RECALL LETTER WE RECEIVED PRIOR TO HAVING BOTH MODULES REPLACED. THOSE BRAND NEW MODULES ONLY LASTED 16 MONTHS OR LESS AND WEVE BEEN DEALING WITH SAME SAFETY ISSUES FOR ABOUT A YEAR NOW, SOME DAYS WORSE THAN OTHERS. ITS A DUMB FLAW AND NEEDS TO BE ADDRESSED SOON BUT WE DONT HAVE ANOTHER $1000+ TO COME UP WITH!! PEOPLE LIKE US, WHO LIVE IN THE SNOW BELT AREAS AND HAVE TO DEAL WITH ROAD SALT AND CORROSION ARE GOING TO KEEP HAVING ISSUES WITH THEM, EVEN THOUGH WE KEEP OUR CAR AS CLEAN AS WE CAN!! ITS A PAIN IN OUR ASSES AND NOT OUR FAULT FOR A LOUSY STUPID DEVICE THAT WILL FAIL HERE!! THANK YOU!!

We are having issues with our bling spot warning system not working warning light stays on in mirror and not going off its seams GM mounted sensor module behind rear wheel which gets exposed to water and then corrodes and malfunctions this also leads to many others safety issues including shutting vehicle down while driving because other systems are connected to it cannot isolate There should be a recall thankyou

Service blind spot detection system alert come on i took it to the dealership and paid 95.00 to diagnosis they wanted 1900.00 to fix the problem 2 weeks later while waiting for an appointment the entire system is failing Forward collision warning, Lane departure warning ,and Parking collision warning. the dealer now wants another 95.00 to re-diagnosis seeing as only the blind spot was the only warning at first. I'm being told this could lead to the vehicle shutting down even while driving

All the lights are flashing on dashboard. Car won't start. No gages work on dash. Lights won't work blinkers don't work. Radio panel is black. I had same issues in 2018 and had to replace detection module and harness on both sides. Paid $1200. Now I am having the same issue again.

Blind spot module has corroded and failed due to water intrusion. The module is very poorly sealed and clearly would lead to corrosion, very poor design. Potential for fire from electrical short is extremely high.

There is a bad sensor I believe on my impala- the passenger blind spot warning light is staying on all the time - even when the car is off.

I received an error Service "Side Detection System". Dealer says it needs to replace the Side Blind Zone Alert Modules (part #84648920) due to water intrusion on the module. They say it can affect the entire dashboard, causing it to fail. The Chevy Impala forums have many mentions of this issue with this car. There have been reports of smoke coming from these modules. GM had issued a Special Coverage N172097060 in 2019 but only covers cars 6 years old or less and less than 80,000 miles. Due to the widespread occurrence of this issue, it should be recalled.

Side detector system

side detection system failing and will not shut off

This is the second time the blind side detection system has failed on both my vehicle and daughter's 2014 Impala. GM is aware of this is a problem and issued a special program, however; it expired last year. This issue can also cause issues with other electrical systems. Spending $1500+ every 2-3 years for an issue that is a manufacturer problem is not acceptabe.

There was a recall on the SBZA in April of 2019 and we received a recall letter from GM, probably in July of 2019 but the recall was for vehicles with less than 80,000 and we had 83,000, so I never pursued recall thinking that we wouldn't qualify. We had the SBZA-Side Blind Zone Alert system replaces in December of 2019, at a big cost to us of $1000, at local Chevrolet dealer. The new detection system only lasted about 15-16 months or March-April of 2021 before it started acting up again. When I called the Chevrolet dealer up to complain about the problem, they told me that there was only a 1 year warranty on brand new part and it being over 1 year old now, it was out of warranty!! Arrgghh!! We left it at that and it didn't cause too much of a hassle as I turned off detection system, using car radio settings and we only had a message on dash, which we could turn off and live with as we didn't have another $1000, out of our pocket, to get fixed. Then in November of 2021 and onwards, the light on drivers mirror would come on, stay on or blink off and on but doesn't always stay on. Now as of February 26 2022, we are having many of the same issues and things happening, that we had back in 2019, where the car is hard to start, dash doesn't work properly along with many safety warning lights coming on the dash, sounds, speedometer not working, no radio, no turn signals, no HVAC, windows don't function properly, etc, etc. It usually goes away, after 10 minutes or so, then is normal again, then goes berserk again, off and on. This is now happening more often each day and is a huge safety issue, esp with our daughter using the car now, to get back and forth to work. She has panicked each time this happens. We bought car with 72,000 miles on it back in May of 2018 and it currently only has 126,300 miles on it. We love this car otherwise as it's been a real great car but now with this stupid problem again and so soon, we are not sure what to do. Thank you very much.

It appears that my vehicle had a special coverage bulletin titled “N172097060 - Special Coverage Side Blind Zone Alert Module Water Intrusion” This special coverage only covered vehicles for 6 years or 80,000 miles. This week I started experiencing problems with my vehicles side blind zone alert system. From everything that I have read it appears to be the same issue that led to the special coverage mentioned above being issued. However, my vehicle is now outside of the specified coverage limitations. I believe that it should still be covered as it still remains a safety issue. Regardless of how many years or miles have passed. Thank you.

The stabilitrak system GM installed on my vehicle repeatedly indicates a "service" notification. Once this occurs, my vehicle loses power and the ability to shift into any driving mode. This issue began around 60,000, I currently have 77,500+ on my vehicle. GM issued a technical service bulletin (PIC5992A) for my vehicle, however, denies it's the issue and will only attempt a repair from a computer code, which they continue to fail to replicate. The occurrence of this issue is especially worrisome on any interstate highway. ODI 11406439

Side detection system has failed. This detection system is vital to the safety of the vehicle. This is because there are blind spots inherent in the cars design that the side detection system corrects. My Impala LTZ is 6 1/2 years old with just under 30,000 miles.

Blind side collision monitor is not functioning properly due to faulty design which allows moisture to get into cabin where the monitor is installed. Causing the collision feature not to function properly and "service side collision" msg to show on the dashboard. I had this issue before and had it repaired by the dealer on 03/2019. The problem has since returned. But this time it's caused the functions on the dashboard ( gas, h/c and speed meters, digital monitor screen etc) to stop working where I can't tell if I have gas or my driving speed or anything associated with the dashboard info system, it blacks out. And now the alert light on the door mirrors continuously stay on even when there's no car on the side of my vehicle and even when the car is turned off. I took it back to the dealership and have been told that the collision monitor sensors AGAIN need to be replaced.

The connector on the drivers side module is corroded from water intrusion. It is an identical condition as described in NHTSA recall N172097060. The dealer and GM claims this vehicle was not included in the recall, even though it is a 2015 Chevrolet Impala. They now want me to pay 1,000+ dollars to fix the issue according to the steps in the bulletin? If i don't get this fixed soon is it could disable my vehicle as explained in the bulletin. I purchase the car in November of 2019 which is 7 months after this bulletin was released, and because GM did not include the VIN number in their system it was never corrected previously. The connector in the images is damaged now because the mechanic broke it at the dealer trying to get it off from the internal corrosion. I also contacted GM directly and they said that my car was not included in the VIN range and that I could take the issue up with NHTSA at my own prerogative.

The blind sensor indicators are defective. The right side stays on but the the left side worked accordingly. Without warning the indicator on the left also stopped working. GM is well aware of the issue but will only fix the issue if it happens within a warranty timeframe. The initial issue with mine happened while driving in a winter storm with slushy roads. The sensors that stays illuminated isn't as much as a safety issue as the one that was lighting up as expected then stopped without warning. This item should be a full recall not a fix it if it breaks scenario. Mine stopped working within my warranty timeframe but because I was a secondary purchaser, I had no way of knowing that waiting until my next oil change would cause me to be stuck with $800 in repairs because GM refused to recall a safety issue item they are well aware of.

JUST RECEIVED A MESSAGE ON THE DRIVER INFORMATION CENTER THAT SAYS "SIDE DETECTION SYSTEM" SO I LOOKED IT UP IN THE WARRANTY INFO BOOK AND FOUND ONLY AN INSTRUCTION THAT SAID TO CLEAN THE REAR BUMPERS, AND NOTHING ELSE. CALLED DEALER AND THEY WANT $135 TO DIAGNOSE AND POSSIBLE REPAIR CHARGE OF $1100. LOOKED INTO COMMON PROBLEMS WITH OTHERS VEHICLE OWNERS AND FOUND SEVERAL WITH IDENTICAL PROBLEMS; ALSO FOUND A GM 'SPECIAL COVERAGE ADJUSTMENT"" DATED 4-1-19 COVERING THE COST OF REPAIR BUT ALSO FOUND IT WAS ONLY GOOD FOR YEARS AND/OR 80,000 MILES. MY VEHICLE HAS 62,000 MILES BUT IS 6 MONTHS BEYOND THE YEARS. IS THIS NOT A SAFETY ISSUE? I WOULD THINK SO. SO WHAT CAN I DO ABOUT THIS, AS I UNDERSTAND IT CAN CAUSE SIGNIFICANT OTHER INCIDENTS WITH THE VEHICLE, SUCH AS LOOSING THE INSTRUMENT PANEL INDICATORS AS WELL AS ISSUES INVOLVING VEHICLE HEADLIGHT AND ENGINE SHUT DOWN. WOULD LIKE A RESPONSE AS SOON AS POSSIBLE AS I WOULD LIKE TO GET THIS TAKEN CARE OF ASAP. THANK YOU [XXX] CELL # [XXX] JUNE 15. 2021 P.S. THIS HAS BEEN THE BEST VEHICLE I HAVE EVER OWNED; UP UNTIL NOW. INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

MY CAR WAS REPAIRED UNDER SPECIAL COVERAGE N172097060, SIDE BLIND SIDE ALERT MODULE, IN APRIL 2019. TWO YEARS LATER THE SAME PROBLEM HAS RECURRED YET NOW I'M TOLD THE SPECIAL COVERAGE HAS EXPIRED, AS THE IN SERVICE DATE OF MY VEHICLE IS 2 MONTHS PAST THE 6 YEAR LIMIT. THE REPLACEMENT PART WAS ALSO SUBSTANDARD, PERHAPS EVEN THE ORIGINAL DESIGN, AS IT DID NOT LAST MUCH MORE THAN TWO YEARS. THE FACT THAT IT FAILED JUST TWO MONTHS AFTER THE COVERAGE LIMIT IS A SLAP IN THE FACE TO ME AS A CONSUMER. THE DEALER CHARGED ME OVER 900 DOLLARS TO REPLACE THE SIDE DETECTION SYSTEM, REQUIRED TO PASS NY STATE INSPECTION.

I HAD THE DRIVER SIDE BLIND SPOT DETECTION GO BAD ON MY IMPALA, SO IT'S STARTING OUT THAT MY DRIVER SIDE MIRROR BLIND SIDE IMAGE WAS BLINKING, THEN IT STOP AND WAS WORKING OK FOR ABOUT THREE WEEKS AND THEN A MESSAGE APPEARS ON MY DASH TO FIX THE BLIND SPOT DETECTION SYSTEM, WHICH IF FINE, BUT WHEN I GO TO THE INTERNET TO SEE IF I CAN JUST DO AWAY WITH THIS SYSTEM, THE FEEDBACK THAT I'VE FIND OUT WAS VERY UPSETTING, EVERYTHING ON DASH DOESN'T WORK, CAN'T GET INTO THE CAR, CARS DON'T START. THAT'S FINE BUT WHEN I TOOK THE CAR TO GET FIX THE SERVICE MANAGER AND WORKER TELL ME ANYTHING CAN HAPPEN WHEN THIS SYSTEM GOES DOWN. WHAT HAPPENS IF I'M DRIVING THE CAR AT HIGHWAY SPEEDS AND IT JUST STOP RUNNING, I HAVE NO BREAKS OR STEERING. IT'S CAUSES AN ACCIDENT.TO ME THIS IS A VERY SAFETY ISSUE. AND NOW THE PASSENGER SIDE BLIND SIDE IS BLINKING NOW, IT STOP BLINKING AND WORKING FINE FOR AWHILE AND THAN JUST QUITE WORKING.

WHEN THE CAR IS TURNED ON AND NOT IN MOTION THE DASH DISPLAYS A SERVICE SIDE DETECTION SYSTEM MESSAGE AND THE BLIND SPOT DETECTORS IN THE SIDE MIRRORS DO NOT LIGHT UP LIKE THEY SHOULD WHEN THE CAR IS FIRST STARTED. WHEN DRIVING, AT ANY SPEED AND ON ANY ROADS OR HIGHWAY, THE BLIND SPOT DETECTORS DO NOT LIGHT. WHEN ASSESSED BY A CHEVY MECHANIC THE SIDE DETECTION SENSORS WERE SWOLLEN AND . CORRODED. THIS SENSOR IS IN AN AREA WHERE IT IS UNPROTECTED FROM THE SNOW AND SALT. IT WILL COST ALMOST $2,000 TO REPLACE TWO SENSORS. IF NOT REPLACED I'M AFRAID THAT MY VEHICLES WILL START CATCHING FIRE OR HAVING OTHER ELECTRICAL PROBLEMS LIKE OTHER 2015 IMPALA OWNERS HAD HAPPEN TO THEM IN THE PAST DUE TO THESE CORRODED SENSORS.

ELECTRICAL MODULE (SIDE DETECTION) HAS FAILED TWICE. HAVE TO DRIVE TO GET REPAIR WITH NO GAUGES, SIGNALS, OR HEAT. THIS COULD EASILY BE A SAFETY ISSUE. THE CAR WAS PARKED, UPON STARTING, GOT SEVERAL ERROR MESSAGES INCLUDING SIDE DETECTION ISSUE, AIR BAG FAILURE, TIRE INFLATION FAILURE. NO SPEEDOMETER, TACHOMETER, HEAT - BUT THE STEERING WHEEL AND SEAT ELECTRICAL HEAT STILL WORK!
