PRODUCTION-ADJUSTED DESCRIPTIVE METRIC

NORMALIZED COMPLAINT CONTEXT

Production-normalized complaint data is not currently available for this vehicle.

This metric compares the number of NHTSA owner complaint records retrieved by CarIQ with NHTSA-reported production volume for the corresponding vehicle population.

It is not a vehicle failure rate. Complaint reporting behavior, vehicle age, time on the road, production definitions, and other factors can affect the result.

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.

Out of nowhere without any warning light all of a sudden couldn’t back up when geared into reverse to reverse. Turned the vehicle off and back on, then was able to reverse. Left parking lot and was on the road and vehicle started loosing speed, then put into park with hazard lights.

EVERYTIME IT RAINS REALLY HARD, MY DRIVERS SIDE B PILLAR WHERE THE HANDLE AND SEAT BELT IS, IS SOAK AND WET FROM A LEAK. THIS HAPPENS ALL THE TIME. I HAVE HAD MY SUNROOF CHECKED, MY WINDSHIELD CHECKED AND DRAIN TUBES CHECKED. THERE IS NEVER ANY WATER OR WETNESS ON THE FLOOR, ITS ONLY THE HEADLINER. THIS HAS BEEN AN ON-GOING ISSUE. I HAVE BEEN INVESTIGATING IF THERE ARE OTHER TAHOES DOING THE SAME AND YES THERE ARE AND 1 HAD WENT TO A BODY SHOP AND THEY FOUND OUT THAT THE MANUFACTURER WELDS WERE NOT WELDED CORRECTLY, WHICH CAUSES WATER TO GET INTO THE ROOF. THIS CAN CAUSE MOLD AND EVENTUALLY OTHER ISSUES. IT HAS STAINED MY HEADLINER. SOMETHING NEEDS TO BE DONE ABOUT THIS BECAUSE I CANNOT AFFORD TO HAVE A BODY SHOP FIX THIS KIND OF REPAIR AND I SHOULD NOT HAVE TO FOR AS MUCH MONEY AS I HAVE PAID FOR THIS VEHICLE. I HAVE VERY YOUNG GRANDKIDS THAT RIDE IN THIS VEHICLE AND ONE HAS VERY BAD ALLERGIES AGAINST MOLD. AND IT IS NOT FAIR THAT I EVENTUALLY WILL HAVE TO GET THIS FIXED BECAUSE IT WILL ALSO CAUSE RUST. PLEASE DO SOMETHING ABOUT THIS.

WHEN IT RAINS REALLY HARD, THE ROOF IN THE B PILLAR LEAKS ABOVE THE SEAT BELT AREA INTO THE HEADLINER. MY HUSBAND WHO IS AN AUTOBODY TECHNICIAN HAS MADE SURE MY SUNROOF LINES ARE CLEAR AND THE WINDSHIELD MOLDINGS AND SEALS ARE GOOD. HE HAD ANOTHER ONE AT HIS PLACE OF EMPLOYMENT WITH THE SAME ISSUE AND IT WAS THE ROOF WELDS, WHICH ARE DONE BY THE MANUFACTURER. I AM HEARING MORE AND MORE TAHOE OWNERS WITH THIS SAME PROBLEM. AS MUCH AS THESE VEHICLES COSTS US, THIS SHOULD NOT BE HAPPENING. THIS CAUSES MOLD IN THE ROOF AND RUSTING. THIS HAS TO BE LOOKED INTO BECAUSE THIS IS AN EXPENSIVE REPAIR IF I NEED TO HAVE THIS PROBLEM FIXED AND COULD ALSO CAUSE HEALTH ISSUES IF NOT ADDRESSED WITH THE MOLD.

The rear AC evaporator located behind the paneling in the rear of the vehicle was leaking AC freon r-1234yf. This was diagnosed after a weeks long troubleshooting by my mechanic trying to find the leak in the rear AC lines causing the vehicle to fail the vacuum test. After he showed me the part and where the cracks were, he suggested I report this as a safety issue since the coolant was leaking inside the car and is highly flammable. He also said he has had many other GM vehicles with the same issue and thought a recall should be issued.

The contact owns a 2018 Chevrolet Tahoe. The contact stated that while driving at an undisclosed speed, the vehicle experienced moderate shuddering followed by a sudden significant reduction of motive power. The vehicle was driven to a dealer, where it was diagnosed that two fuel injectors and the associated electrical wiring harness, and the fuel pump had failed completely. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 143,000.

NHTSA complaints are reports submitted by vehicle owners and other consumers. Complaint counts do not represent the percentage of vehicles affected and do not by themselves establish that a safety defect exists.

A higher complaint count can partly reflect how many vehicles were sold, vehicle age, and other factors. CarIQ does not yet normalize complaint counts by vehicles sold.

OFFICIAL NHTSA MANUFACTURER COMMUNICATION DATA

MANUFACTURER COMMUNICATIONS

TOTAL COMMUNICATIONS0

No NHTSA manufacturer communication records were returned for this year, make, and model.

Manufacturer communications include service bulletins and other technical information submitted by manufacturers to NHTSA. The existence or number of communications does not establish how often a condition occurs or whether an individual vehicle will experience it.

Some manufacturers may issue more detailed service documentation than others, so communication counts should not be used alone to compare vehicle reliability.

NHTSA DEFECT INVESTIGATIONS

TOTAL INVESTIGATION RECORDS0

No applicable NHTSA defect investigation records were returned for this year, make, and model.

NHTSA investigations evaluate potential motor-vehicle safety defects. The existence of an investigation does not by itself establish that a safety defect exists, and the absence of an investigation does not establish that a vehicle is problem-free.

Open and closed describe NHTSA's process status, not a CarIQ reliability judgment.

OFFICIAL NHTSA SAFETY RECALL DATA

SAFETY RECALLS

3 recall campaigns found

01SERVICE BRAKES, HYDRAULIC:POWER ASSIST:VACUUMCampaign 20V603000October 1, 2020

Summary

General Motors LLC (GM) is recalling certain 2018 Cadillac Escalade, Chevrolet Silverado 1500 and Tahoe, GMC Sierra 1500 and Yukon vehicles equipped with either a 5.3L or 6.2L V8 engine. The output of the mechanical vacuum pump can decrease over time, decreasing the amount of vacuum/power brake assist.

Safety Consequence

A decrease in brake assist can increase the brake pedal effort and distance required to stop the vehicle, increasing the risk of a crash.

Remedy

GM will notify owners, and dealers will reprogram the Electronic Brake Control Module, free of charge. The recall began November 11, 2020. Owners may contact GM customer service at 1-866-522-9559, Cadillac customer service at 1-800-458-8006 or Chevrolet customer service at 1-800-630-2438. GM's number for this recall is N202300860.

Additional Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

02SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:WHEEL SPEED SENSOR/TONE RINGCampaign 19V761000October 24, 2019

Summary

General Motors LLC (GM) is recalling certain 2015-2020 Chevrolet Suburban, Tahoe, and GMC Yukon, and 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 vehicles equipped with a 5.3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the Electronic-Brake Control Module (EBCM) software may activate the driveline-protection system.

Safety Consequence

Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.

Remedy

GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began December 11, 2019. Owners may contact Chevrolet customer service at 1-800-630-2438 or GMC customer service at 1-800-462-8782. GM's number for this recall is N192261050.

Additional Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
