• 12/23/2018· VEHICLE SPEED CONTROL

  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.

• 12/07/2018· ELECTRICAL SYSTEM

  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.

  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.

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.

I PULLED OVER IN A HOTEL PARKING LOT TURN THE VEHICLE OFF OPEN THE DOOR AND THEN STARTED THE VEHICLE BACK UP. THE RADIO DID NOT WORK. I WENT TO MCDONALD'S TO HAVE BREAKFAST IT WAS ABOUT 30 MINUETS BEFORE I GOT BACK IN THE TRUCK STARTED IT UP AND THE RADIO STATED TO PLAY. I THOUGHT IT WAS STRANGE SO I CONTINUE TO DRIVE 2 DAYS LATER MY CHECK ENGINE LIGHT CAME ON SO I TOOK IT BACK TO THE DEALER TO SEE WHAT WAS WRONG. THEY TOLD ME THAT THEY CLEAR THE CODE AND NOTHING WAS WRONG WITH THE VEHICLE SO I THEN GOT AN OIL CHANGE SINCE THE VEHICLE WAS ALREADY IN THE SHOP.

  I had an accident in this vehicle where the airbags deployed upon impact (as they were designed). However, once airbags deployed, my vehicle was filled with smoke (from the airbags) and all of my windows were covered and I couldn't see out. Panic set in as I tried to get out of the vehicle and my door would not open. After several moments I thought about the door locks, they were engaged of course. Once I realized and hit unlock, the door opened. This isn't an issue as far as parts being a defect or anything like that, but today I heard of a Texas DPS Trooper being in an accident in his Tahoe. His took a front impact as well, and the person trying to help him couldn't get him out of the vehicle. It made me wonder if his locks were engaged too, and him being more severely injured may not have thought about the door locks. This could be a potential safety risk, especially if the vehicle is on fire. What if vehicle manufacturers were able to install a safety mechanism that would automatically release the door locks if an impact was detected, or air bags were deployed? Just merely a suggestion as none of the parts on my car failed, they all did their job, but not being able to get out of your car is terrifying. I'm not sure if I am in the right place to pass on this suggestion, so if not, please advise where I might leave one. Thank you.

• 10/15/2022· POWER TRAIN,ENGINE

  A lifter collapsed, which in turn damaged the lobes of a piston, which then damaged the camshaft...generating a repair bill of $7,100 per the dealer. The vehicle only has 69,200 miles on it. When the lifter failed, the car shuddered at stops, lost some power and made a noticeable clanking noise. When pulling out from stops, or into traffic, the car hesitated somewhat before accelerating. This creates a very dangerous situation. Also, if more lifters or the camshaft seized up at higher speeds, a driver could experience a potentially fatal situation from an uncontrollable vehicle or a fire. Research shows that Chevy/GM knew about the lifter problem on 5.3 ltr engines with their AFM system for years and sold them anyway. They apparently have never solved the problem, and it still exists today. Several class action lawsuits have been lodged against them for the lifter failure problem. Aside from the serious potential safety issues, an expensive vehicle like my Tahoe should not be expected to incur a $7,100 repair bill when it's only 4 years old and has less then 70,000 miles on it. That's ridiculous. My wife and I are both retired. We will be tapping our retirement account to pay for this shoddy Chevy product and will worry that it just might occur again, after the fix. From a safety standpoint, a stall, loss of power, or engine seizure at speed will tax our quick response reflexes. The known lifter problem is a legitimate safety situation and needs to be addressed before someone is seriously injured or killed...if they haven't already. Thank you for listening.

  The contact owns a 2018 Chevrolet Tahoe. The contact stated that in 2024 the front windshield was damaged, and the windshield was replaced. The Insurance Company was notified and requested that an aftermarket windshield be placed on the vehicle. In May of 2025 the contact noticed that the Chevrolet Assist Camera behind the rearview mirror had failed. The vehicle was taken to the dealer, who determined that since the windshield was not an OEM windshield replacement, the part caused the camera to fail. The camera was unable to be calibrated. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 82,000.

  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.

  I OWN A 2018 CHEVROLET TAHOE PREMIERE WITH THE RST 6.2L PERFORMANCE PACKAGE. THIS VEHICLE HAS THE OPTIONAL PERFORMANCE FRONT BRAKE UPGRADE SYSTEM. I RECEIVED THE FOLLOWING RECALL: GM PROGRAM # N182155600, CUSTOMER SATISFACTION PROGRAM #18119 - SPARE TIRE DOES NOT FIT OVER PERFORMANCE FRONT BRAKE KIT. THE VEHICLE HAS A 17 INCH SPARE TIRE WHICH WILL NOT FIT OVER THE FRONT BRAKES WHEN EQUIPPED WITH THE PERFORMANCE BRAKE KIT. THE SOLUTION PROPOSED BY CHEVROLET FOR A FLAT FRONT TIRE IS A DUAL TIRE CHANGE (REPLACE A REAR TIRE WITH THE SPARE AND MOVE THE REAR TIRE TO THE FRONT). THE CHEVROLET DEALER IS TO PRINT AND INSTALL AN INSERT TO THE OWNER'S MANUAL DESCRIBING THIS DUAL TIRE CHANGE. THIS SOLUTION COMPROMISES SAFETY, ESPECIALLY IF THE DUAL TIRE CHANGE HAS TO OCCUR ON THE SIDE OF A BUSY HIGHWAY. IT DOES NOT MEET MY EXPECTATIONS FOR A PREMIUM SUV. CHEVROLET SHOULD PROVIDE A SPARE TIRE (FREE OF CHARGE) THAT WILL FIT OVER THE PERFORMANCE FRONT BRAKE KIT. AN APPROPRIATE SPARE TIRE SHOULD HAVE BEEN INCLUDED WITH THE FRONT BRAKE UPGRADE OPTION. I CALLED THE CHEVROLET CUSTOMER ASSISTANCE CENTER REGARDING THIS ISSUE. THEIR REPRESENTATIVE WAS RUDE AND NO HELP AT ALL. HIS ONLY REPLY WAS THAT I NEEDED TO TAKE THIS MATTER UP WITH MY CHEVROLET DEALER. SO I DID THAT AND THE DEALER CHECKED WITH THEIR CHAIN-OF-COMMAND WITHIN CHEVROLET. THEIR ZONE REPRESENTATIVE STATED THAT THERE WAS NOTHING ELSE THEY COULD DO OTHER THAN PROVIDE THE OWNER'S MANUAL INSERT. MY COMPLAINT IS NOT WITH THE DEALER. I DO NOT EXPECT THEM TO PROVIDE AN APPROPRIATE SPARE TIRE AT THEIR COST. A RIM AND TIRE FOR THIS VEHICLE (THAT WILL FIT OVER THE PERFORMANCE FRONT BRAKE KIT) IS VERY EXPENSIVE. MY COMPLAINT IS AGAINST GM AND CHEVROLET CORPORATE REGARDING THEIR UNACCEPTABLE RESPONSE TO THIS PROBLEM.

  As I drove the 2018 Chevy Tahoo the brakes got really hard to press and would no longer stop. I was finally able to get it to stop and moved off the road. The vehicle was towed to the AutoNation Chevrolet Mesa Dealership (6330 Superstition Springs Blvd. Mesa, AZ 85206). I was told that the vacuum pump seized causing the brake belt to break. I was told by another mechanic that there is a recall on the hydraulic vacuum pump breaking system....... As the vacuum level drops, the brake assist decreases, increasing braking effort, extending the distance required to stop the vehicle, thereby increasing the risk of a crash. Summary: General Motors LLC (GM) is recalling certain 2015-2017 Cadillac Escalade, 2014-2018 Chevrolet Silverado, GMC Sierra, 2015-2018 Chevrolet Suburban, Tahoe, GMC Yukon vehicles. The amount of vacuum created by the vacuum pump may decrease over time.

  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.

  LT275 65 R18 123/120 R DOT 1 BE BP AT 21 My daughter has pictures of the tires, all four tires (all bought at the same time) 05/6/23 from Discount Tire, are splitting along the side wall, originating at the tread line, we have talked with Discount tire, there are 40,000 miles approximately on the tires. They have been appropriately rotated and balanced. There have been no repairs of the tires. This is noted to be a defect, not normal wear and tear of the tire, per Discount Tire. They have offered 423.00 credit to purchase new, and have come back with 50% off new tires. Since this is a defect, verse actual wear and tear I do not believe that is appropriate. 75-100% of the replacement value. The tires should reasonably last between 5-6 years. The defect increases the risk of a blow out on any one or several of the tires. Discount Tire in Lubbock has confirmed that there is an issue, but I am not happy with their resolution.

  The Body Control Module does not work. A new BCM was installed in my car in April 2025. Since then I am having multiple issues, but the safety related issue is with the trailer braking system. It is available for inspection upon request. The dealership is unwilling to try another BCM without it costing me $600 for labor. If I am unable to use my brakes, then I put myself and others on the road at risk. The problem started with a Tire Monitor System. I was told I needed a BCM to fix the problem so the car would not throw codes. Now, I am being told the problems with the brakes are not comiing from the BCM. THERE WAS NOTHING WRONG WITH MY car until I took it to this dealership for a new key faub and a tire pressure monitor error. The Body Control Module in a 2018 Chevy Tahoe Premier does play a role in controlling the sunroof. More specifically, the sunroof system is supplied power through a fuse located in the driver-side fuse box which is connected to the BCM. The sunroof switches communicate with the BCM via a serial data circuit, and the BCM then commands the sunroof to open or close. Therefore, the BCM acts a central hub in the electrical system of the vehicle and communicates with the sunroof control module to operate it. I learned this from two other dealerships. One dealership in West Virginia and another dealership in Texas told me this information about the BCM controlling the sunroof and many other electrical parts of the 2018 Chevy Tahoe Premier. To make it simple, the BCM was replaced. The vehicle is now having serious issues. I consider an unintended activation of the braking on the wheel which causes the vehicle to pull to one side puts me at risk of a crash. Is this yet another failed sensor or part due to the negligence of the service department at Smith Buick when replacing the BCM and programming a key faub?

  First occasion the car drove fine with no indication of an issue. Then once the car was turned off then on, the dash showed no lights or gauges and indicated that the steering assist is not working and the wheel was impossible to turn (almost like a limp mode but not driveable). Disconnected the battery to try and clear the issue and car drove home fine. Was told it could be a bad battery so replaced the battery and it worked fine for about a month. Then again with no indication did it again and this time it cleared itself after about 30 minutes. Dealer said there was a short in the negative battery ground cable and an open circuit in the rack and pinion mechanism but that the rack and pinion part was not available and they weren’t sure when it would be (probably due to excessive failures). Replaced the negative battery ground part and everything was fine for about 3 months until today when the car did the same thing again. We will have to keep looking for the unavailable part or I will basically have a $30k paper weight. Very concerned at the possibility that the steering will go out while I am driving as others have mentioned in previous posts. Seems as though something tragic will have to happen before they issue a recall of a part that appears to be a common failure.

  I have a 2018 Chevrolet Tahoe. Today, while I was pulling out of the Sam's Club parking lot I heard a huge thud, the car jerked forward and completely stopped. The drive line / drive shaft had broken clean off. I'm awaiting official diagnosis from Riverton Chevrolet's service dept., but it was a very scary situation. I'm thankful that I was not rear ended or hurt. I see that welding issues are part of a NHTSA safety issue on later model Chevy Tahoe vehicles. I'm wondering if my 2018 is a victim of a similar problem. I do not drive at high speeds or go off-roading. I get my car serviced regularly. This could have been catastrophic if I'd been on the freeway. Repair invoice pending.

  My 1.5 year old daughter is able to press the button on the chest clip and release the chest clip by herself. The button barely requires any pressure to be applied before releasing. She is unbuckling herself frequently.
