    The vehicle whose VIN and other identifying details are stated above was sold on May 27 by [XXX] , owner of Koza Transportation LLC, to my company, Skyturk Transportation LLC, which I established in the United States. At the time of sale, the vehicle’s mileage was represented as 395,204 miles and supported by video and photographic evidence. However, subsequent investigations revealed that the same vehicle had been listed and sold on April 29 through BidCars with a recorded mileage of 843,194 miles. This clearly shows the odometer was rolled back by the seller or individuals acting with his knowledge. The vehicle, with reduced mileage, was sold to me at a grossly inflated price. It was also later discovered to be a severely damaged/salvage vehicle, a material fact not disclosed at the time of sale. After I brought this to the seller, he initially stated he would repurchase the vehicle but later claimed he could not contact the person he bought it from and gave inconsistent statements. Information obtained thereafter confirmed these actions constitute a federal offense. Official reports have been filed with the District Attorney’s Office and the DMV through my attorney, and legal and criminal proceedings are ongoing. Due to the investigation, mileage irregularities, and the vehicle’s damaged status, it cannot be sold at this time. My authorized stay in the United States is nearing expiration. As a result of the seller’s actions, my company has been unable to operate and suffered serious financial losses, and I have personally incurred significant damages. I respectfully request necessary actions to protect my legal rights and address the damages suffered.I learned on September 18 that the odometer had been tampered with and that the vehicle I also respectfully request that necessary measures be taken to prevent the seller or any individuals acting similarly from engaging in such vehicle sales to others in the future, and that stricter penalties be applied.

    I have experienced this issue a few times, and so have several acquaintances who drive the same make and model of truck as I do. Whenever it rains or I go through a truck wash, the starter shifter blocked comes on the screen while driving, causing the RPMs to fluctuate and resulting in a complete loss of power to the vehicle. One dealership informed me that this is a common problem, attributed to moisture seeping into a harness located near the transmission. Tried connecting the truck to a computer so see fault codes nothing comes up because it's a glitch and clears out. This situation poses a serious risk, as it could potentially lead to a fatal accident. With no proof of the malfunction.

    While driving on the highway on cruise at 70mph the right front brakes locked up. The day was clear. I was driving across a bridge. The truck pulled to the right and I fought to pull it back on to the road. My company has the incident on camera. I was pulling a loaded tanker. Had the pavement been wet or snowy I could have easily jack knifed. If a vehicle would have been next to me I would have struck them. The vehicle was inspected by our mechanic and was told the system was within specs. The truck has also hard braked and pulled to the right when vehicles in the lane next to it are turning.

    A collision avoidance system (CAS), also known as a pre-crash system, forward collision warning system (FCW), or collision mitigation system, is an advanced driver-assistance system designed to prevent or reduce the severity of a collision. System applied brakes bringing our Unit to a complete stop traveling 55 MPH on an Interstate while making a lane change, Because of this our Unit was rear-ended by another CMV, On board cameras video on both V1 and V2 clearly show incident. A print out of the DDEC shows code for braking system control at exact time of incident. In our fleet we have the same 2020 Freightliner Cascadia with this system and in trying to maintain the safety of our drivers and equipment no to mention our Insurance cost and CSA scores, This is a major issue as you can see on the Web the many cases and stories of these same incidents happening. Direction is needed Thank You

    Semi was traveling on the highway and transporting a 48,000 pound steel coil. The steel coil was secured with 4 chains. The automatic emergency braking system engaged with nothing in front of the vehicle, causing it to suddenly come to a dead stop in traffic. This caused the steel coil to break free of its bounds, crash through the trailer and into the vehicle cab, trapping the driver.

    Ascending Tehachapi Pass CA Hwy 58 Eastbound in the left lane grossing 45,000lbs and traveling at 55mph with cruise control ON. I was passing another slower moving truck(~35-40mph). Before I came along the other vehicle the highway curved to the left. The Collision Aviodance System(CAS) didn't alarm, however the cruise control cut power and Automatic Emergency Braking(AEB) hardbraked my truck reducing the speed from 55mph to 40-45mph. This was sudden and unexpected. Once I determined the issue, I applied throttle overriding the AEB/CAS. However my forward momentum was lost and accelerating uphill was slow. It was midday and clear skies. No one was following me fortunately, but sudden and unexpected braking could have had a vehicle tailing too closely(It was an uphill grade with a speed limit of 65 mph for POV) rear-end my trailer(48 foot stepdeck trailer). Please explain to me how CAS/AEB are safety systems for a CMV?!? This is the 4th report I have filed with NHTSA about the same Freightliner Cascadia tractor. According to the vehicle operating Manual that this occurrence of unexplained and unwarranted braking is a "feature" of this "safety system". Meaning that the CAS/AEB was functioning as designed(A flawed designed in my professional opinion). I have been contacted by the NHTSA about previous filed report about an ongoing investigation with the manufacturer. What action is this agency going to take? Will there be an investigation when the system performs as designed causing an avoidable accident, injury, or death? Will I be a defendant, witness, or victim?

    On Off ramp I-40 W Segliman, AZ there was a cattle guard 10 feet before Stop sign. I was braking for Stop Sign. AEB(aka CAS Collision Aviodance System) detected the cattle guard grate as obstruction, not something flat of the pavement, and apply maximum braking(Note: I was already braking). It had been snowing that night thou at this location the road was dry. Unnecessary panic braking by automated system can cause lose of control of vehicles on wet and icy surfaces. How is it safe for the AEB/CAS system to over ride the operator's action? Doesn't the CDL driver who is a trained and licensed professional have the ability to identify and take appropriate action, in this case a cattle guard grate wasn't a safety concern, whether to brake or avoid the obstacle? I have had numerous instances that I have and haven't reported to NHTSA of the deficiencies of the AEB/CAS falsely reading the conditions and taking the incorrect action.

  10. Filed Mar 1, 2023Failure Mar 1, 2023Akron, PAUnknown or other

    In this truck, and in other CMVs with down-facing exhaust, and with complete aerodynamic panels, exhaust gases are trapped under the body, and are circulated into the cab. Much worse when parked, but noticeable when driving. I can smell regen soot in the cab when moving at highway speed, meaning that exhaust is getting from the exhaust pipe to the cab interior. This vehicle VIN has this problem, but i have found it to be present in most other newer models of CMV, to varying degrees. The style of exhaust that ends above the roofline (vertical stacks) do not present this problem. This particular vehicle has no auxiliary power unit, so when idling is necessary, enough exhaust makes it in the cab to cause coughing. The down facing exhaust design, coupled with aerodynamic panels that trap and funnel exhaust gases to the interior of the cab, are a critical design flaw. CMV drivers are constantly breathing varying levels of exhaust gases, even when driving. I have thermal videos of exhaust, from a parked truck, moving from the tailpipe forward to under the hood. Every gas under the hood and sleeper body ends up in the cab and sleeper. As a test, fluorescent leak detecting liquid could be aerosolized into the exhaust stream near the end of the tailpipe, or outside the tailpipe near the exhaust pipe opening. After idlng for a while, and after driving with the leak detection liquid being sprayed, a black light could be used to show everywhere the gases go. Drivers cannot idle the trucks nor drive down the road without being firced to breathe exhaust for up to 20+ hours a day. These gases, including the burnt regen gases/soot, are bad for the worker's health, and can impair cognitive function. Also, this is a clear violation of DOT and EPA safety rules for CMVs. Since the DOT rules state that exhaust cannot be expelled under the hood or cab/sleeper, the exhaust is designed to come out a few inches behind the sleeper. The exhaust still comes into the cab.

    Multiple safety issues with truck #1 When driving & using cruise control (CC) at 60 mph & truck is at that speed (60 mph) truck is moving from top speed to E coast mode. Immediately RPM is down (from 1250 to 600) & steering wheel is much harder b/c reduced power from engine . Response time for driver to avoid potential hazardous situations on the road (i.e. animals, rocks, trees, etc.) is longer & not safe #2 This problem is related to when truck is in regen. In driving, and when truck is doing regen (visible on the dash: high temp light/ icon). CC set to (60 mph) when truck is at that speed (60 mph) truck goes to E coast mode. RPM is going down to 600 RPM which is not adequate engine speed to finish regen. With regen interrupted there is a lot of white smoke under the truck and red light for engine shut down is on the dash. There is 30 seconds time to override shut down but at the same time the driver needs to safely park the truck on the shoulder, on a busy highway, with reduced power and steering wheel (600 RPM or no power at all because engine shut down). With high DPF temperature,there is potential for fire (truck,grass,trees ). I am told engine shut down was caused by interrupted regen process. #3 Collision warning is coming with no reason, and can activate active brake, at high speed. Radar malfunction (snow, ice in the front)can cause malfunction to adaptive cruise control, active brake assist, & malfunction other safety features. Combination of malfunction (radar, active break assist, collision warning, IPM [intelligent powertrain management], engine break not engaging) can cause dangerous acceleration for heavy loaded truck. I contacted DTNA (Daimler Truck North America) in regard to these issues & am told in order to solve these issues the truck should be inspected where mechanics and programmers are involved. At the same time I spoke with the company I work for about safety issues with those trucks. You can contact me for further information.

    CAS actived with a Collision Warning and applied hard braking for about 1/2 second for a vehicle that stopped in a paved turnout. The stopped vehicle was not in the travel lane. There was a slight left curve and I could see the stopped vehicle. I thought the CAS May trip because I had experience FALSE Collision Warnings many times in the 88,000 miles I have driving this truck. Before the CAS Collison Warning alerted, I was not in cruise control and was accelerating with the throttle. As stated before the CAS applied hard braking for 1/2 second. I have read the Driver’s Manual about the Driver Assist, Active Braking Assist(CAS) Section 5. On page 5.6 Table 5.2 is says that the above situation can trigger Collision Warning and braking. This may be so, however this has on numerous occasions FALSE Warnings, applied partial braking, and 3 times emergency braking for vehicles that were not traveling in my lane. Earlier this year, Freightliner had a road service mechanic in my company yard to verify that current software and working Driver Assistance Systems on our fleet of trucks. Mechanic determined that this truck was up to date and no recalibration was required. I’m very concerned that the CAS will activate in poor weather conditions, causing a lost of control of the vehicle OR I maybe rear ended by a following vehicle when there is no reason for my vehicle to be stopping. I cannot have the CAS deactivated because it would violate manufacturer, company, and insurance policies.

    Wednesday 13 July, 2022 6:45pm PDT. Location US395 Lakeview, OR. Collision Avoidance System(CAS) applied maximum AEB braking for a false detection of obstruction in my travel lane. I was following a pickup and horse trailer at about 45mph. The pickup signaled a left turn and slowed. I applied minimum braking. The pickup and trailer turned clearing my travel lane(the tail end of the trailer was in the opposing lane). At this moment the CAS detected a collision warning(I was still applying some braking) and the AEB slammed on the brakes for about half second then canceled. The CAS has falsely detects numerous incidents a day for the 7 months I have driven this truck. The above incident has been the most severe. Other false incidents range from warning(without braking), cutting power to engine, to applying some amount of braking. At NO TIME during this period did the CAS detected a true obstruction. Manufacturer has checked that truck's system software is current and properly calibrated.
