2018 Chevrolet Tahoe Owner Complaints

I PURCHASED A 2018 TAHOE 20 DAYS AGO AND AT 45 MPH AND 65-75 MPH I FEEL PRESSURE IN MY EARS WHICH THEN MAKES ME FEEL NAUSEOUS WHICH LEADS TO SEVERE HEADACHES. THIS BUFFERING OCCURS EVERY TIME I DRIVE IT. I HAVE TRIED DRIVING WITH THE WINDOWS DOWN / UP, RADIO ON / OFF. NOTHING CHANGES TO LESSEN THE EFFECTS. I GOGGLED SEARCHED IT TODAY AND FOUND SEVERAL REPORTS AND COMPLAINANTS ABOUT THIS ISSUE BUT BOTH GM CUSTOMER ASSISTANCE AND MY DEALER SAYS THEY NEVER HEARD OF THE PROBLEM. THE PRESSURE OCCURS ON LOCAL ROADS AND HIGHWAY, EVERY TIME BETWEEN THE SPEEDS OF 45-55 AND 65-75 MPH.

COLLISION ALERT SYSTEM DOES NOT FUNCTION WITH ENOUGH WARNING DISTANCE ON THE SEAT VIBRATION AND RED FLASH PROJECTION ON THE WINDSHIELD. THE DRIVER ESSENTIALLY MUST NEAR COLLIDE WITH AN OBJECT OR VEHICLE FOR THIS FEATURE TO WORK. THE YELLOW CAUTION INDICATOR IN THE DASH DISPLAY WILL LIGHT-UP BUT THE SEAT VIBRATION AND RED FLASH ON THE WINDSHIELD DOES NOT FUNCTION. CHEVROLET DEALERSHIP INSISTS IT WORKS PROPERLY, I CONTEND IT DOES NOT BASED THE FUNCTIONALITY OF THE PREVIOUS MODEL I OWNED, A 2015 TAHOE. THIS SAFETY FUNCTION ADVERTISED BY CHEVROLET DOES NOT FUNCTION AS INTENDED.

SERVICE BRAKE ASSIST MESSAGE ON DASH BOARD. THIS YEAR MAKE AND MODEL HAS A RECALL BUT MY VIN# IS NOT SHOWING AN ISSUE THOUGH MY VEHICLE IA HAVING BRAKING PROBLEMS. DEALER SAYS NO RECALL FOR MY VEHICLE. WHY NOT MY VEHICLE? IT IS DEFINITELY THE ISSUE UNDER THE 2018 TAHOE RECALL.

WE JUST HAD TO SPEND $1,000 TO HAVE THE RADIATOR REPLACED ON OUR 2018 CHEVROLET TAHOE BECAUSE IT WAS LEAKING WHICH ONLY HAS 32,050 MILES ON IT. THE TAHOE HAD A 3 YEAR 36,000 MILE BUMPER TO BUMPER WARRANTY, BUT WE WERE TWO (2) DAYS PAST THE 3 YEAR MARK SO THEY WOULD NOT COVER IT. THE TAHOE ALSO HAS A 5 YEAR 60,000 POWERTRAIN WARRANTY, BUT THE DEALERSHIP SAID THAT THE RADIATOR IS NOT CONSIDERED TO BE PART OF THE POWER TRAIN ONLY THE HOSES GOING FROM THE RADIATOR TO THE ENGINE WERE COVERED UNDER THE POWERTRAIN WARRANTY. IN JANUARY 2019 GM ISSUED SERVICE BULLETIN PI1513F (ATTACHED) FOR 2015-2016 TAHOES FOR THIS EXACT SAME LEAKING RADIATOR ISSUE WHICH STATES THAT THE RADIATOR REPLACEMENT SHOULD BE COVERED UNDER THE POWER TRAIN WARRANTY. THIS IS A KNOWN ISSUE FOR 2017 & 2018 MODELS ALSO, BUT GM HAS NOT ISSUED A RECALL, NOR WILL THEY COVER THE 2017-2018 MODEL UNDER THE 5 YEAR 60,000 MILE POWER TRAIN WARRANTY LIKE THEY DO WITH THE 2015-2016 MODELS.

On July 29, 2022 my Tahoe broke down on me while driving home from work. It started to lose speed while on a busy highway during rush hour. I started losing speed and I kept giving it gas and it wouldn’t go. I kept trying to get speed to try and get off the highway to avoid getting into an accident or put someone else in danger. Somehow I managed to get off into a shopping center. I had come up to a stop sign and couldn’t even get the Tahoe to stop while there was a lot of traffic in the shopping center as well. I eventually got it to a safe spot and called a tow truck. I live almost an hour from home. The shop the Tahoe was towed too said the torque converter was contaminated with metal shavings that was caused by parts on the Tahoe grinding together and therefore contaminating the torque converter and then it ruined my transmission. I was also told this is a common thing they are seeing with Chevy Tahoes, but yet no recalls have been issued and I think something needs to be down about it. It put my life in danger as well as other drivers around me! And I couldn’t afford to fix it so I lost my vehicle and all the hard work and money I put into paying my vehicle since 2018! I also found a lawsuit regarding this issue too.

WHEN ACCELERATING IT SOUNDS LIKE MY VEHICLE IS STUCK IN BRAKE DEGRADING OR IS MAKING THAT DISTINGUISHING NOISE. MY VEHICLE IS IN THE SHOP FOR THE SECOND TIME TO FIX THE SAME ISSUE OF PARK ASSIST, SIDE DETECTION AND FRONT CAMERA SERVICE. WHEN EXPRESSING MY CONCERN FOR THIS PROBLEM OF THE SOUND THE DEALERSHIP SAID LET'S FIX THE SERVICE ISSUES FIRST AS EVERYTHING IS ELECTRONIC. I HOPE MY VEHICLE IS SAFE TO DRIVE.

Transmission issues on 2018 Chevy Tahoe. The vehicle stopped on the Hwy. Dealership says the transmission needs to be replaced. Is uncertain why the transmission has gone out on the vehicle since it’s only 4 years old. Error message came on my vehicle and I called the dealership. From my research it appears Chevrolet is continuing to have problems with the transmission on its Tahoes. This is unexceptionable. The consumer has to pay the price not the manufacturer. Please assist.

BACK UP CAMERA HAS ZERO VISIBILITY WHILE BACKING UP DURING NIGHT IN DARK AREA WITH RAIN CONDITION. THE REAR BACK UP LIGHTS DO NO ILLUMINATE ENOUGH LIGHT TO GUIDE THE VEHICLE. THE CAMERA IMAGE IS TOO GRAINY, DISTORTED AND PIXELATED.

ON THE EVENING OF NOVEMBER 27TH, MY CAR WITH 10,200 MILES HAD MULTIPLE ISSUES MAKING IT UNDRIVABLE. I ATTEMPTED TO PULL MY CAR OUT OF A PARKING SPACE. WHEN I PUT THE CAR IN DRIVE, I FELT A HARD THRUST. THE THRUST WAS SO HARD THAT I FELT LIKE A CAR HIT ME. I ATTEMPTED TO PUT THE CAR IN REVERSE; HOWEVER, IT WOULD NOT REVERSE WHEN I STEPPED ON THE GAS PEDAL. WHEN I PUT THE CAR IN DRIVE, IT BARELY MOVED. AS IT MOVED, I FELT THE POWER STEERING LOCK, AND I COULD NOT MOVE THE STEERING WHEEL. I TURNED THE CAR OFF AND ON THREE TIMES AND ENCOUNTERED THE SAME ISSUES. AT THIS POINT, I WAS STUCK IN THE MIDDLE OF A PARKING LOT IN A ODD PLACE WHERE CARS HAD TO GO AROUND ME. WHEN THE TOW TRUCK ARRIVED TO MOVE THE CAR, THE DRIVER ENCOUNTERED THE SAME ISSUES. HE POINTED OUT THERE WERE NO RPMS ON THE CAR. THE TOW TRUCK DRIVER HAD TO TOW THE CAR FROM BEHIND, AS I WAS STUCK IN AN ODD POSITION AT THE EDGE OF THE PARKING LOT. AFTER TWO WEEKS, MY CAR REMAINS AT THE DEALERSHIP. THE DEALERSHIP STATES IT'S A COMPLEX ELECTRICAL ISSUE. THEY ARE WAITING TO FIND OUT IF GM CAN FIX IT OR WORSE....THEY WILL JUST GIVE IT BACK. I AM BEGGING TO HAVE THIS INVESTIGATED AS I WOULD HAVE FOR ANYONE OR MYSELF TO ENCOUNTER THIS FAILURE WHILE DRIVING.

AFTER TAKING IT BACK TO THE DEALER IWAS TOLD THE HEADLIGHT ASSEMBLY WAS BAD. THE DEALER ORDERED A NEW ONE. IT HAS BEEN 2 MONTHS.I CALLED GM PARTS AND WAS TOLD THERE WERE NO HEADLIGHTS LIKE THIS IN THE USA. NO DEALERS HAVE ANY IN STOCK. THESE ARE THE INTELLIBEAM HEADLIGHTS. IN MOTION ON STATE HIGHWAY.

THE BRAKE PEDAL IS TOO CLOSE TO THE DRIVER IN RELATION TO THE GAS PEDAL. THE DISTANCE OF EACH PEDAL CANNOT BE ADJUSTED INDEPENDENTLY. A DRIVER'S FOOT CAN BE TRAPPED IN BETWEEN THE TWO PEDALS BECAUSE OF THE GAP. IN A FATAL SITUATION, IT TAKES LONGER FOR THE RIGHT FOOT TO MOVE FROM THE GAS PEDAL TO THE BRAKE PEDAL SINCE THE RIGHT FOOT CANNOT JUST MOVE LATERALLY TO THE LEFT, BUT IT NEEDS TO GO AROUND.

Caliper became stuck which produced smoke coming from tire. Had the caliper replaced. Then months later my forward collision system activated because a car in front of me stopped abruptly. After the car automatically braked to slow my car down, the brake never released and became stuck and the ABS light came on. Replace the abs sensor and two days later the brake engaged on its own while doing 60 mph on the highway. Now whenever the hill assist, collision warning, or anything else is activated, the brake engages and gets stuck. In addition, at times on the highway my brake will engage on its own.

4100 Miles - Asked service dept. at dealership to check for noise coming from underside of vehicle. No service was completed. 4800 Miles - Asked service dept. at dealership to check again for noise on suspension. Service indicated it was a parking brake cable that was rubbing. 9800 Miles - Asked service dept. at dealership to check fluttering noise coming from engine. No service was completed. 15,000 Miles - Asked service dept. at dealership to check again for rattling noise coming from engine. Service indicated fluttering heard was exhaust pulsing through the manifold. No service was completed. 21,000 Miles- Service Dept at dealership provided multi point inspection and given clear inspection. No service was completed even though I stated there was still engine noises. 24,000- Asked service dept. at dealership to check hard shifting from transmission and poor performance. In addition, mentioned the noises again. No service was completed, service stated it was due to colder temperatures. 25,000- Asked service dept. at dealership to check hard shifting from transmission and poor performance. In addition, mentioned the noises again. Engine cooler lines were replaced. Scanned and verified clutch learn values all normal. Activated TCC and disabled TCC and found normal operation. No service completed. Now, after warranty has expired, service at dealership is telling me my camshaft and lifters need to be replaced, struts are leaking, transmission needs attention and should be flushed, and that I should NOT be driving my vehicle due to safety concerns. Although, I had taken the vehicle in multiple times during warranty period with complaints about these very items, no service was ever completed to correct them. Since then, I have read multiple articles documenting GM issues with L87 6.2L engines and transmissions. I'm filing a formal complaint with GM, as these issues should have been communicated to consumers or fixed through recalls.

My vehicle recently has had 2 issues that I have taken in to the Service Shop for 3 times and the problem has not been fixed. My most concerning issue is my brakes. My brakes are doing the exact problem indicated in this article: https://www.consumerreports.org/car-recalls-defects/gm-recalls-suvs-and-pickups-for-braking-issue/ When the brakes malfunction, I feel a vibrating brake pedal, feels like my vehicle is not going to stop on time, I hear a ticking noise from the engine and my Brake Assist Service light comes on. The issue continues until I can pull over and restart the vehicle. It is a very uneasy feeling having to drive a vehicle that you do not feel safe in. I called 800 Chevrolet's Customer Service number provided in the article and they are unaware of the recall mentioned in this article. I do not know where to go from here. I just want my vehicle fixed and to feel safe. My 2nd issue is regarding my Adaptive Cruise Control. I've had it in the shop 3 times for this also and they did replace a part but that did not fix this issue. I will be driving down the highway or interstate and out of the blue my alarm starts dinging, the seat vibrates, the cruise control gets kicked off and I get an alert on my dash stating that the Adaptive Cruise Control was disabled. Each time it has happened to me there is nothing around but it immediately starts reducing my speed. If someone were behind me it could cause a crash because of the unexpected speed limit reduction. When you go in to look at recalls on 2018 Chevrolet Tahoes it shoes that there is 3 of them that have been issued, yet my VIN is not included in any of them? What can I do from here? I've called Chevrolet's 800 # and they created a "High Urgency Case" but I have not heard back. Attached are my copies of service records and vehicle summary showing there has never been recalls on my VIN #.

1- the second row center Seat Belt Receptacle stopped locking so failed, this happened while using the vehicle. 2- the seatbelt receptacle stopped latching while using the car in Seattle, I had to drive with someone in that seat unbuckled because all other seats were being used. 3- the receptacle can not be repaired, needs to be replaced; 4- I have contacted the manufacturer to have them fix this but they will not do it without compensation. 5- no warning. the vehicle is not old and in very good condition. I drive with my family in the car daily but rarely need to use the middle seat. I feel this is a defective latch due to the limited use and age of vehicle. I am concerned that the other seatbelts will also break without warning and Think that GM needs to be aware of a possibility.

While driving home, the the FAC, forward automatic crash, indicator light came on, I applied the brakes and watched to my dismay as my vehicle slowed down but would not stop. I applied steady hard pressure until impact with another vehicle in front of me. The FAB, forward automatic braking system never kicked in. I will contact the dealer concerning the above issue.

When I started car I got service messages for side detection system, tire monitor system, safety restraint system, front camera system, trailer break system and theft deterrent system. Each one gave option to dismiss. When I would dismiss the messages would come back. When I was driving, all the things on dash, mph, oil, battery etc all stayed on zero. Super dangerous and I could have died!!!!!!. No blinker sound
