Chevrolet Shudder Service Bulletin 16-NA-175

16-NA-175: Shake and/or Shudder During Light Throttle Acceleration Between 25 and 80 MPH (40 and 128 KM/H) at a Steady State – (Oct 11, 2018)

 

Some customers may comment on any of the following conditions:

A shake and/or shudder during light throttle acceleration between 25 and 80 mph (40 and 128 km/h) steady state driving when transmission is not actively shifting gears. A shudder feeling that may be described as driving over rumble strips or rough pavement. Shudder feeling is evident in both Drive and M7 MY15-16 & L7 MY17, MY18 and MY19 mode.

Important: Do NOT replace the torque converter or transmission assembly for this condition. Engineer reviews have proven that replacing the torque converter does not provide a long-term solution to TCC shudder. A revised service procedure will be released in Q1 of 2019. If the vehicle experiences a repeat shudder condition, this document should be followed again. All part replacement claims will be subject to engineering analysis. Any part(s) determined not to be defective will be subject to a possible claim debit.

1. Comments

Chevrolet Colorado owners have experienced significant problems with shudder and hesitation and here are some typical complaints,

“my truck has started randomly doing a quick vibration (fast paced vibration like driving over rumble strips on highway) that typically lasts a second or less.  Sometimes it will do it multiple times over a perioid of several seconds, other times its just a quick vibration.  Its a pretty significant vibration, I really can feel it in the steering wheel and the entire column shakes.   Seems like all interior pieces vibrate as well.”

Land Rover Freelander Engine Problems

Land Rover owners have reported repeated engine problems.

1. Head Gasket Problems, Overheating, and Engine Failure  

Many head gasket failures have been reported on the Freelander engine on the vehicle and it has been determined that this has been commonly caused by a condition where a cylinder sleeve  has “dropped” in the engine block (meaning that the top of the sleeve has moved below flush with the head gasket surface of the block).  The condition occurred often enough that Land Rover issued a bulletin (Technical Bulletin #0036, dated June 16, 2004) for it’s dealership technicians to provide a process for
inspection and evaluation when a vehicle came in for repair.

This bulletin also addresses an overheat condition diagnosis and repair, and engine overheating often accompanies head gasket failure. The head gasket would have failed primarily because the tension of the crushed compression seal ring would be compromised as the sleeve moved lower into the block and away from the cylinder head, ultimately allowing coolant intrusion into the combustion chamber and combustion gases into the cooling system.

Volvo XC 90 Check Engine Light

Volvo XC90 purchasers have complained of various problems including check engine light.

1. NHTSA Complaints

Here are some typical complaints

The compressor (or another component controlling the HVAC system in the 2018 XC90) failed while driving. The heat inside the vehicle quickly raised.  In October 2018, I again, finally, took the 2018 XC90 to the service department because (1) the check engine light came on; and (2) the electronic safety systems, such as the auto braking, had automatically engaged without any cars around the vehicle. The vehicle was also driving and handling in a strange manner.

F250 and F350 Tailgate Opening Problem

Owners of the Ford F250 and F350 have complained unexpected tailgate openings.  If you experienced this problem you may be entitled to compensation or a new vehicle.


1. Reported Complaints

One source reports,  www.carcomplaints.com/news/2018/ford-f-250-f-350-tailgates-opening.shtml

The F-250 and F-350 trucks are equipped with electronic tailgates that can be opened with the key fobs, but five owners filed complaints saying the tailgates opened without warning and uncommanded. Here’s a sampling of the five tailgate complaints received by NHTSA.

“While driving 45 mph, the tailgate inadvertently opened and damaged the tail lights.”

“The rear tailgate will open randomly on its own. I’ve taken it in and nothing was done.”  Another 2017 Ford Super Duty truck owner says the tailgate has dropped about 17 times and finally the tailgate opened as the truck was going 65 mph on a mountain road and damaged the trailer and tailgate. The driver also said the experience caused him to disconnect the wiring to the tailgate. An F-250 owner said the truck had less than 5,000 miles on it when the tailgate dropped opened uncommanded three times. The driver says the tailgate and trailer were damaged. Finally, another truck owner complained the tailgate had open uncommanded at least 12 times while driving. The dealer had no answer about how to repair the problem and further said there was no way to disable the tailgate lock. The driver also complained there is no warning light to indicate when the tailgate is open.

2. Tailgate Opening Service Report 

Ford had issued a technical service bulletin (TSB) 17-2196 to dealers in October 2017 for 2017 F-Super Duty trucks built on or before June 7, 2017. Titled “Intermittent Electrical Concerns, Rear Parking Aid Camera Inop And/Or Uncommanded Tailgate Opening,” the TSB talked about a wiring harness numbered 14405.

The bulletin said the Super Duty trucks could suffer from water intrusion into the wiring harnesses and cause uncommanded tailgate openings. In addition, there may be a loss of communication on the speed controller area network (MS-CAN) and water intrusion could also cause problems with the rear-view cameras.


3. Repairs 

Ford dealers were told the tailgate problems could be fixed by the following methods.

2017 F-Super Duty 6.2-liter: Inspect connectors and replace the wire harness and include the time to remove/install the fuel tank, evaporative emission canister and replace one of the female side connectors.
2017 F-Super Duty 6.7-liter: Inspect connectors and replace the wire harnesses and include the time to remove/install the fuel and reductant tanks and to replace one of the female side connectors.
NHTSA’s investigation could be concluded in various ways. It’s possible safety regulators may find nothing wrong to indicate a safety defect, or they could upgrade the investigation. It’s also possible NHTSA could find what it believes to be a safety defect and request that Ford orders an official F-250 and F-350 tailgate recall.

2017 Chevy Duramax 6.6L Turbo – Diesel V8 Engine Problems

A number of owners of the 2016-18 Chevrolet with the Duramax engine have been complaining about substandard performance, emission codes, and other engine problems.

Owners may be entitled to compensation or replacement vehicles.


1. Typical Complaints

I have an 2018 Chevy 2500HD with a Duramax L5P engine introduced in 2017. I’ve owned it for 19 days and it has been back to the dealer in and around their shop for 12 days. It is showing codes for malfunctioning emission system. The dealer thinks it is a faulty Diesel Particulant Filter and/or can not figure why it is plugging. These issues are not new with the L5P engine and have been around since mandated in 2011 with the then new LML engine. My question is just how wide spread are these issues. And my problem down the road is, if I trade the truck back should I get another and risk the same problems or just try to get my money back and wait for GM to get their act together.
