    system is done again

    A class action against General Motors states,  “shuddering, shaking, jerking and hesitation is related to internal issues within the transmission and/or torque converter causing undue friction and impairing proper functioning
    of hydraulic systems and gears, which in turn results in metal shavings being circulated throughout the transmission. This damage to the transmission and torque converter imposes escalating repairs upon consumers, including the need to flush the metal shavings from the transmission. Because of
    the Transmission Defect, the Class Vehicles present a safety hazard and are unreasonably dangerous to consumers. ”  Shelton v. General Motors, Case 2:19-cv-11802-S

There have been a number of complaints about the Cadillac Touch Tone Display.  A class action states,

GM has concealed a dangerous defect from its customers
who purchased or leased 2013 to 2017 Cadillac ATS, SRX and XTS vehicles and
2014 to 2017 Cadillac CTS, ELR and Escalade vehicles equipped with GM’s
“Cadillac User Experience” touch screen display (the “CUE System” or “CUE”)
(collectively, “Class Vehicles”). Among other things, the CUE System controls
the vehicle’s climate, navigation, audio/Bluetooth/communications, and back-up
camera. GM’s conduct is especially egregious because the defective CUE
Systems pose serious safety risks.

GM Colorado Hesitation

General Motors May Face Class-Action Lawsuit Over Defective 8-Speed Transmissions

Models affected include the Chevrolet Silverado and Colorado, as well as the GMC Sierra and Canyon

The filed class-action lawsuit affects the Chevrolet Silverado as well as the GMC Sierra. Plaintiffs in the lawsuit allege General Motors’ 8-speed transmissions are defective.

Certain Chevrolet, Cadillac and GMC models built between 2015 and 2019 may have a defect in their 8-speed transmissions, according to a class-action lawsuit posted to GM Authority spotted the lawsuit, which says there are serious problems with GM’s Hydra-Matic 8L90 and 8L45 transmissions.

More specifically, the transmissions have a defect that cause vehicles to hesitate and jerk when accelerating or coming to a stop. The lawsuit reads, “These transmissions have a common defect…Drivers have reported that the shift is sometimes so violent, they feel as though they have been hit by another vehicle.”

It also mentions the case of an owner whose vehicle shifted from reverse to drive harshly enough that it nearly lurched through his garage door. The defect centers around the transmission itself or the torque converter. Over time, any shuddering, jerking or hestitation may cause internal issues, including metal shavings being circulated throughout the transmission.

See In Re Gen. Motors Air  Conditioning Litigation   Our office is presenting claims for inconvenience, repair cost reimbursement and other relief.

Is there a cost to me to present an individual claim

Our office handles Chevrolet air-conditioning claims on a contingency basis with no payment required from the consumer.

What Vehicles are Covered

Car air conditioning
Problems have been reported on GM trucks and SUVs, namely the Cadillac Escalade (model years 2015-2017), the Chevrolet Silverado 1500 (model years 2014-2016), the Chevrolet Suburban (model years 2015-2017), the Chevrolet Tahoe (model years 2015-2017), the GMC Sierra 1500 (model years 2014-2016) and the GMC Yukon (model years 2015-2017).

What types of Problems Have been Reported

“The first time the car had less than 1k miles on it!! It feels like a transmission problem. I am familiar with the system where the car will turn itself off while at a stoplight and then back on again- I’m fine with that system. What is not okay is when driving in DC rush hour traffic, accelerating, braking, or slowing down and the car will violently jerk. The first time it felt as if I was rear-ended.”  2016 Chevrolet Malibu – Consumer Review, Edmunds.

Chevy Silverado and GMC Steering Defect

NHTSA logo

General Motors has recalled almost 700,000 2014 Chevy Silverado 1500s and 2014 GMC Sierra 1500s  for a steering defect following a National Highway Traffic Safety Administration investigation (NHTSA # 17V414000).  The steering defect can cause a potentially dangerous problem driving and turning.

These trucks’ power steering assist (“EPS”) can cut out, especially during low speed turns, and then return suddenly.  This may result in a loss of control of the vehicle.  Additional symptoms of the problem may include other electrical systems cutting out and warning light indicators going off.

According to GM the underlying problem is a defect in the EPS module software, which needs to be reprogrammed.

If you are having steering problems with your 2014 Chevy Silverado or GMC Sierra, call the Law Office of Howard Gutman for a free consultation on your claim.

General Motors Air-Conditioning Problems

  1. Causes 

Condensor, fluid, and the overall system have been identified as the source of problems.
As the class action explains, “The first defective component is the line leading from the compressor to the condenser. This line consists primarily of an aluminum tube connected to a rubber hose. On information and belief, this line can fail in two ways. First, the aluminum tube can become disconnected from the rubber hose, creating an opening in the line that can allow refrigerant to escape. Second, the aluminum tube itself has a material defect that can allow the tube to rupture, also allowing refrigerant to escape.   GM has recognized this defect. It no longer manufactures the compressor to condenser line that was original equipment in the Class Vehicles.

General Motors instructed mechanics that if they find a failure in this line, they are to replace it with a newly designed line and install a bracket in the system to minimize flexion and movement of the compressor to condenser line. (Exhibit A). Unfortunately, customers who suffer this failure after the vehicle is out of warranty are required to purchase and pay for the installation of these new parts, thus having to pay twice to obtain a functioning air conditioning system.

    2. Vehicles Covered 

Vehicles with the Class Defect include the 2015 to 2017 model Cadillac Escalade and Escalade ESV; the 2015 to 2017 model Chevrolet Suburban; the 2015-2017 model Chevrolet Tahoe; the 2014 to 2017 model GMC Sierra 1500; the 2015/2016 model GMC Sierra Heavy Duty; the 2014 to 2017 model Chevrolet Silverado 1500 and the 2015/2016 model Chevrolet Silverado Heavy Duty

Chevrolet Equinox Check Engine Light 2.4L 4 Cylinder 35,000 mi,

Check engine light on,,, P0014 code, Oil consumption, ticking sound
2013 Chevrolet Equinox – 2.4L 4 Cylinder 44,800 mi,
Engine light came on and I had it checked and this is the code that came up. The dealership told me it was an exhaust camshift sensor, currently this was not covered under my warranty, however the dealership I bought it from is paying for the repair cost since I bought the vehicle this way…

P0014. Just discovered. Haven’t repaired yet.

2012 Chevrolet Equinox – 2.4L 4 Cylinder 89,000 mi,
Valve camshaft issues p0014

Reduced engine power light on. Issue with camshft timing. Engine nneds torn apart and new camshafts and timing belts not happy…

2011 Chevrolet Equinox – 3.0L V6 88,000 mi,
PCM code displayed and was repaired at no cost by dealer. However now vehicle will not start on two separate occasions since vehicle returned. Is it related? Vehicle will only start after being jumped and starts fine for about 3 weeks then has to be jumped again??????

Actually the problem happened when I first bought the car used and I traveled 3hrs. away from my home in the winter and it was snowing ungodly when the car started shutting down and stating engine power low. The dealership I bought it from replaced the gas pedal they said. Well, its happening again and I am very concerned with my children in the vehicle when this happens I have no control. The steering wheel locks up and the car just shuts down. It is doing this again, but it has been riding rough for awhile. The code states its the throttle sensor. But who knows, there a several engine recalls. I don’t know, but I think GM needs to replace these vehicles at no cost! Our lives are more important then their bank accounts being debited!
