I bought Achilles desert hawk uhp 285/50/R20 tires in late 2019 from Walmart . and had them mounted in 2020 from discount tire. Within 10 months of tires being mounted I had a vibration and it was getting worse every day so I started looking at it and found I had a separated tire on the driver's side front. I put my spare on and contacted Walmart which told me sorry for your luck and there is nothing they can or will do.so I contacted discount and they said to contact Achilles tire. I did and never heard back from them. I then forgot about it until roughly 5 months ago when passenger tire was separated. Then 3 days ago the passanger rear separated and now today the driver's rear has separated. I understand 1 tire possibly 2, but to have all 4 tires separate in less than 2 years and in under 10,000 miles is mind blowing to me..I have all the tires and I filed a complaint with Walmart and Achilles after the 2nd one. I honestly don't think it's discount tires responsibly. I only had them install tires because walmart would make excuse after excuse and I got fed up with it. There should be some sort of liability to the manufacturer and to Walmart. I am asking you if it's possible to look into this. 4 tires separate in 2 years you ée⁷⁷e77⁷e⁷

In the past I have sent several emails to Chevrolet corporate office re the ABS brake system on my Tahoe which first failed with only 130 miles on the vehicle. Vehicle almost tipped over but I recovered the braking system and stopped vehicle only inches from going off a cliff and into the ravine below. I love my Tahoe which now has 109000+ miles on it but the ABS brake system has never worked and on several occasions almost wiped out myself and a passenger because brakes failed to engage. I filed several complaints with the Chevrolet dealer in Austin, TX where I bought my Tahoe and also here in Taos, NM where I currently live. Recently I had the Chevrolet dealer here in Taos run a diagnostic on my ABS brakes. Result was that the brake system was defective and would cost $2000 to repair! I feel Chevrolet should pay for the repair since my Tahoe was delivered from the factory with defective ABS brakes. As it is, my Tahoe cannot be resold since the system as is could kill anyone in this vehicle if they did not know how to recover when pedal is all the way to the floor and vehicle is picking up speed rather than slowing down. Certainly even I could hit an elk standing in middle of highway because I would not be able to recover brake system in time.

Rear steel brake lines rusted out. I was driving on the highway at about 50 miles per hour and the brake pedal went to floor & had to pump brakes. Had to turn off to berm of road to keep from hitting car in front of me. Had to have rear brake lines replaced and the mechanic suggested all brake lines be replaced because of the rust. I had all the brake lines replaced for over $600 dollars. The tahoe has only 41000 miles on it and almost caused an accident. It happens all of a sudden & it take a few seconds before you can figure out what to do, taking much longer distance to stop. They need to recall these brakes as soon as possible before more accidents happen.

Live in minneapolis, and just lost the brakes on my 2001 chev tahoe LT this week. Had been going down I-494 at 65 mph minutes before this. Four blocks from my house driving on a main road, snowy and icy, made a left hand turn to my side street, and the car kept going straight. Hit the brakes, the ABS activated, and the brake pedal went all the way to the floor. virtually no brakes, but I managed to complete the turn without hitting anything, and limp it home. In the garage now getting fixed, estimated $500 - $1,000. with some googling and talking to 4 garages, it seems to be a pretty common problem. Amazing to me that gm has not been forced into a recall over this. This could be fatal, if it hasn't been already.

While driving my chevy tahoe I experienced complete brake failure luckily I was able to stop the vehicle with the use of the emergency break and I did not have an accident. I had no indication that the breaks were going bad until I lost them completely. I had the vehicle towed to a shop the mechanic told me that two break lines were busted and that the rest were corroded. He told me that he has done 5 chevy break line systems in the last 3 months an apparently this IS a know issue with chevy trucks. It seems like the break lines only last a few years before they are corroded and rusted and eventually the break without warning or notice this IS unsafe and I think chevy needs to do a recall on this issue. I have never had any break line issues with any other make of vehicle.

- Brake line corrosion failure
On January 11, 2011, ODI opened EA11-001 to investigate allegations of premature brake line corrosion failure in model year (MY) 1999 through 2003 General Motors (GM) full-size pickup trucks and sport utility vehicles sold or registered in the following region of the United States that NHTSA has viewed as salt states…
On January 11, 2011, ODI opened EA11-001 to investigate allegations of premature brake line corrosion failure in model year (MY) 1999 through 2003 General Motors (GM) full-size pickup trucks and sport utility vehicles sold or registered in the following region of the United States that NHTSA has viewed as salt states for investigations of corrosion related issues:Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia and Wisconsin.The subject vehicles represent the first five MY's of GM's GMT800 platform production, of which approximately 2,038,504 vehicles were sold in salt states (the subject vehicles).The GMT800 platform includes the following vehicles:1999-2007 Chevrolet Silverado and GMC Sierra 1500, 2500 and 3500 series pick-up trucks; 2000-2006 Chevrolet Suburban, Chevrolet Tahoe and GMC Yukon sport utility vehicles; and 2002-2006 Cadillac Escalade and Chevrolet Avalanche sport-utility vehicles.General Motors produced a total of approximately 10,427,062 GMT800 vehicles for sales in the United States, including almost 5 million that were sold in salt states.Although there are over 60 different brake pipe routing configuration used in GMT800 vehicles, with the exception of the rear crossover pipes in MY 200x-2007 vehicles that changed from rear disc to drum brakes, all of the vehicles use brake pipes from the same supplier with a common double-wall, brazed steel pipe design with a combination of hot dip Zinc-Aluminum corrosion protection coating and Aluminum paint outer layer known in the industry as AlGal (ASTM-B750). ODI analysis of field data regarding GMT800 vehicles identified a total of 3,645 complaints of brake pipe corrosion failures, including 107 alleging crashes, and 40 injuries.Though only 20% of total GMT800 production, due to age and region the subject vehicles account for a disproportionate share of the failure experience; with 2,702 of the complaints (75%), 88 of the crashes (82%) and 20 of the injuries (50%) reported in those vehicles.Analysis of the complaints showed strong correlations to vehicle age and region.For vehicles with less than 8 years of service, the complaint rates were minimal for all regions.In the salt states the failure rates begin to climb as the vehicles advance in age, particularly in the Northeast corner of the United States.The complaint rates in the salt states go from less than 0.1 incident per thousand vehicles (IPTV) at 7 years in service to over 1.0 IPTV after the 12th year of service for the subject pickup trucks and utility vehicles.Most of the failures reported to ODI occurred in vehicles with more than 10 years in service.ODI?s investigation did not identify any specific defect conditions that were causing or contributing to the brake pipe failures.Nor did the analysis isolate the problem to any subject vehicle sub-populations when analyzed by vehicle type or production range.The investigation found that vehicles experiencing brake pipe corrosion failures were likely to have general patterns of excessive corrosion on the majority of the brake pipe assembly and appear to be occurring due to expected wear out for the brake pipe coating material used in the subject vehicles and the environmental conditions in severe corrosion states.A safety-related defect has not been identified at this time.Accordingly, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will monitor t

In a letter dated august 29, 2005, gm notified odi that it was recalling certain model year 1999 through 2002 c/k pickup trucks and sport utility vehicles to correct a problem with anti-lock brake system (ABS) wheel speed sensor corrosion that may result in unwanted ABS activation and extended stopping distances during low-speed braking (recall 05v-379).gm's recall covers approximately 804,000 vehicles currently registered in the following 14 salt-belt states:connecticut, illinois, indiana, massachusetts, maine, michigan, new hampshire, new jersey, new york, ohio, pennsylvania, rhode island, vermont, and west virginia.the recall procedure will involve removing the sensor, cleaning the mounting surface, applying a rust inhibitor (zinc-x) to the surface, and reinstalling the sensor.if necessary, the sensor will be replaced. The population and failure report data given in this resume are for the full region that has been considered by odi as the salt-belt.that includes delaware, iowa, maryland, minnesota, missouri, wisconsin and the district of columbia in addition to the 14 states included in 05v-379.the states covered by gm's recall have the highest incident rates for the subject condition, accounting for 91% of the incidents, but only 24% of subject vehicle sales in the united states.odi's analysis determined that 840 of the complaints, 244 of the crashes, and 16 of the injuries identified in this investigation occurred in those states.the resulting incident and crash rates are 96.2 and 28.0 per 100,000 vehicles respectively (note:rates are based on vehicle sales, not registered vehicles). The corresponding numbers in the excluded portions of the salt-belt are 399,000 vehicles, 81 incidents (20.3 per 100,000 vehicles), 3 crashes, and no injuries.the statistics in the remaining 30 states are 2,406,000 vehicles, 168 incidents (7.0 per 100,000 vehicles), 31 crashes, and one injury.gm and odi are continuing to monitor the problem experience in states that are not included in the recall.gm will provide odi with updated complaint, field report, and warranty data in november 2005.odi and gm will review that data and assess the appropriateness of the current scope of the recall at that time.

The automatic locking retractor (alr) IS a feature incorporated in the subject vehicle for locking the webbing to properly secure a child safety seat into a vehicle.this pe was opened based on a gm technical service bulletin stating that with certain child safety seats the webbing may not remain locked.there are no complaints in the odi database and only two complaints to gm.gm's instructions state for the final step in using the webbing lock feature to push and pull the child restraint to be sure it IS secure. If the alr IS not locked, the user would be fully aware of this condition prior to completing proper installation of the child safety seat in this vehicle.this investigation did not uncover any complaints of the alr inadvertently unlocking while the vehicle IS in motion.the emergency locking retractor (elr) feature remains available to lock the retractor in a crash.a safety-related defect has not been identified at this time and further use of agency resources does not appear to be warranted.accordingly, this investigation IS closed.the closing of this investigation does not constitute a finding by nhtsa that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.see attached summary for additional information.

This investigation involves the general motors corporation (gm)throttle body (tb) utilized in model year (my) 1999-2002 silverado, sierra, tahoe, suburban, avalanche and yukon (subject vehicle(s)) with 4.8L, 5.3L, and 6.0L engines. The tb valve may intermittently stick in a closed position.in such a situation, an operator may apply additional accelerator pedal force to increase engine speed.the application of additional accelerator pedal force, to open a stuck throttle valve, may open the throttle valve more than intended and, in turn, accelerate the engine and vehicle more than intended and reasonably expected by the driver.on august 1, 2002, the office of defects investigation (odi), of the national highway traffic safety administration (nhtsa), opened this engineering analysis.the investigation revealed that two factors may cause the defect: 1) tb manufacturing process problems; and 2) accumulation of deposits (a pcv system by-product) on or around the tb throttle valve and bore.odi concludes that the tb performs in a defective manner after analyzing gm?s data submissions, and test data collected by the vehicle research and test center (vrtc).fifty-nine crashes are alleged to have occurred as a result of gm?s tb defect.the majority of the crashes involve a single vehicle, engaging in a close quarter vehicle maneuver (or low speed), and causing only minor property damage.four out of the fifty-nine crashes involve injury, and those injuries were minor.although gm?s tb IS defective, based on the evidence gathered, odi has found that the accelerator pedal force required to open a stuck throttle valve IS negligible, and the throttle valve does not stick in the open position.therefore this engineering analysis (ea02-015) will be closed at this time.the closing of this investigation does not constitute a finding by nhtsa that a safety-related defect does not exist.for a detailed discussion of the tb component and testing, please see the attached report.
