General Motors Customer Service Issues

I own a [redacted] Silverado [redacted] HD with a Duramax engine. A week ago, my low coolant light came on, and I brought it to my local dealer. They found the bottom tank empty and conducted a leak test with no results. I suspect the dealership may not have filled the coolant properly after the engine block heater recall, as they charged me $[redacted] and claimed my coolant sensor is faulty. I'm concerned about the EGR valve issues in these engines and frustrated that the coolant tank sensor isn't replaceable separately, requiring a full tank replacement. I am disappointed in General Motors' handling of this issue and warranty support. As a long-time GM supporter, this experience makes me hesitant to purchase from them again.

I brought my [redacted] XTS Cadillac to Bill Black Cadillac in Greensboro, NC, solely for a new cue screen and an inspection as my car was running smoothly. The service rep Brady texted me that my shocks were locked up, which was unexpected. Upon picking up my car, I noticed it was shaking while driving, which was not the case before. Manager Tim McGee was unhelpful, refusing to take responsibility and dismissively attributing the issue to the lift they used. Despite my loyalty as a customer, I was met with rudeness and resistance in finding a solution. My car remains with them as driving it is unsafe. While they offered to replace the shocks at cost, I believe they are accountable for the damage. I seek a fair resolution to this matter. Thank you, Ms. Pamela Price

Our [redacted] Silverado, which has 23,[redacted] miles, broke down recently due to faulty lifters in the engine and needed to be towed to the nearest dealership, located over an hour away from our home. After researching the issue, I discovered that this has been a known problem with this engine since [redacted]. It appears that GM would replace all lifters if the vehicle had less than 8,[redacted] miles. As this is our 5th or 6th new Silverado, bought because it is our primary vehicle for our cross-country trips in the spring, having a dependable vehicle is essential for us. We are concerned about driving a car with faulty lifters and facing the risk of getting stranded. The dealership has only offered to replace the lifters on one side. As retired individuals requiring a reliable vehicle, we urgently need GM to address this issue with the [redacted] Silverado and consider a replacement as a solution. We have contacted Customer Service and have an ongoing case (9-[redacted]) concerning the absence of a loaner vehicle as indicated in the warranty, but are still awaiting a resolution.

I would like to return my [redacted] GMC Sierra [redacted] Duramax. I have been attempting to contact a Tier 2 member in the Legal Department but have had no luck reaching Farris by phone or email. My truck has a starting issue that no one has been able to resolve despite multiple service department visits since I bought it in July. I am feeling frustrated with the lack of response from General Motors' customer service team when I call daily for assistance. Even after providing requested video evidence of the problem, I have not received the help I need. This experience has left me disappointed with the level of customer care from GMC/GM. I am seeking guidance on how to proceed with returning the vehicle due to its ongoing issues.

I visited the Chevrolet dealership in Montgomery, AL, as my A/C was causing fluid to leak onto the driver's side floor. Following repairs identifying a leaking heater core, my car was in the shop for two weeks. Initially, the A/C worked without issue, but the leaking resumed shortly after. After contacting my service advisor, I was advised to return in a week. I had already paid $1,[redacted].26 for the repairs. I find it frustrating to wait for another fix when payment has been made. Despite reaching out to the Service Department Director and not hearing back, the delay in resolving the issue is disappointing, and the customer service experience has been unsatisfactory.

I recently purchased a Pontiac G6 with a 20,[redacted]-mile or 2-year warranty. Unfortunately, the car is leaking water from various areas, causing significant damage. The dome light, sun visors, seatbelt on the passenger side, backseat, and back passenger floorboard are affected. This has led to mold in the back seat, non-functional stereo speakers due to water damage, ruined carpet, and rust issues. I have discovered that many other G6 owners have experienced similar problems, some attributing it to a short tube issue. I am disappointed that the dealer who sold me the car denies any responsibility and suggests contacting GM instead. The situation is concerning, especially considering the health risks associated with black mold, particularly for my children who sit in the affected areas. I am looking for guidance on what can be done and whether any coverage applies to address these issues effectively.

I recently purchased a [redacted] Buick Enclave in January, mainly concerned about the sunroof leaking. After hearing water sloshing in the back a few weeks ago, I took it to the dealership. They cleared the drain ports, but the issue persisted after a rainy night. The dealership insisted the noise indicated a blocked port, but I disagreed. They claimed they couldn't help further without knowing the exact leak spot. Frustrated, I feel reluctant and disappointed in my purchase decision and future Buick loyalty.

Hello, I leased a [redacted] Chevrolet Trax with only 5 miles on it. Recently, after the lease ended, we purchased it with less than 21,[redacted] miles, mostly highway driving. The tires now have 4/32 of tread left. GM is offering to cover only 40% of the cost for the same tires, which doesn't seem fair considering they are still under warranty for 72 months or 60,[redacted] miles. My spouse and I, both in our seventies and disabled, cannot afford $[redacted] for four tires of the same quality. We believe that a 60% replacement by GM, including service costs and better quality tires, would be more reasonable. The current offer is disappointing and does not reflect well on GM or their dealership, Central Maine Motors in Waterville, ME. Any guidance on how to handle this situation would be greatly appreciated. Thank you, Dale V. and Sheilya V.

I'm contacting about my mom's [redacted] Denali Acadia. The headlights are melted and need replacement, including the assembly for both. We had an extended warranty which recently expired in September. I'm hoping the warranty can still cover this repair as the issue has been ongoing for some time.

Hello, I have a [redacted] Suburban Premier where I had a Lighted Bow Tie installed last September at the dealership. Unfortunately, it now only lights up on one side or not at all. Similarly, I had a [redacted] Silverado with the same issue with its Lighted Bow tie. These illuminated bow ties are costly to only last one year. I suspect the warranty period has expired (1 year from install date). I would appreciate assistance in getting this replaced. Thank you. J.

I am having difficulty getting my [redacted] Buick Encore repaired at any local dealership. The issue is intermittent, where the car won't crank or start. Sometimes, if I adjust the positive battery cable, it will start. Despite replacing the battery, starter, and multiple other components costing nearly $[redacted], there has been no improvement. The car has now been sitting for 10 weeks awaiting a battery cable part [redacted]6, on order from the dealer but not supplied by GM. I had to wait three months for a catalytic converter two years ago. At this point, the car is not usable. I am considering taking this vehicle to the scrap yard and purchasing a Ford instead.

Hello, I'm Tina B., and all my vehicle services are done at the GMC dealership in Rutherford County, TN. In February [redacted], I brought in my [redacted] Terrain for an oil change and mentioned oil leaks, which they initially didn't address. Eventually, I had to return due to leaks and had various parts replaced for $[redacted].75. Then, on Nov 15, [redacted], I went back because of a loud rattling noise. They advised engine replacement for $[redacted] due to internal piston issues. I'm dissatisfied that this major problem wasn't detected earlier, considering the earlier costly repairs. The service advisor, Ann W., lacked friendliness and professionalism, telling me I could get future oil changes elsewhere. After the engine replacement, I had to return the car for leaks, which Ann questioned until confirming the low oil level. Despite my significant spending of over $10,[redacted] within 6 months, her behavior was dismissive. I believe the initial repairs were inadequately done and may have led to the engine replacement later. I am reaching out to address and hopefully resolve these ongoing issues at the dealership.

I am looking for the torque specifications for the motor mounts I just replaced on my [redacted] Saturn SW2. I replaced the top passenger side motor mount, the "dog bone" motor mount below the battery, and the "dog bone" motor mount near the front passenger side tire. I am about to replace the transaxle motor mount and want to make sure I tighten the nuts on the bolts correctly. Your assistance with the torque specs would be greatly appreciated. Thank you, Cruz G.

I have heard that GMC might bring back the Avalanche, a vehicle I have enjoyed owning for many years. I have a suggestion for the design of the new model: extend the rear seat room to make it more comfortable for adults. By adding approximately 7 inches to the cab, similar to the GMC Sierra Short Bed's dimensions, it could greatly enhance the backseat experience. The Sierra offers 43.4" of legroom in the rear compared to the Avalanche's 39.1", as well as 44.5" of front legroom versus the Avalanche's 41.3". Additionally, the Sierra has a longer wheelbase at [redacted].4" compared to the Avalanche's [redacted].0". Utilizing the Sierra [redacted] chassis for the new Avalanche could address these concerns. If GMC implements these changes, I would excitedly be the first to purchase one and part ways with my [redacted] Sierra [redacted]. Thank you for considering my feedback. Best regards, R. John Shields

I recently purchased a used [redacted] Envision Avenir with Vin # LRBFZRR45MD179093 and [redacted] miles on it. The in-dash drive mode originally displayed 4 driving modes: Tour, (AWD) All Wheel Drive, Sport, and Off-Road. After receiving a new keyfob from the dealer, the dash info now only shows 3 driving modes: Tour, Sport, and Snow/Ice. I am unsure why this change occurred. The dealer claims it should only have 3 modes, stating that only all-wheel drives have the four driving options. However, I distinctly remember it initially showing four modes. Any insights would be appreciated. Thank you, Richard Ely.

I recently purchased a [redacted] Silverado from Sterling McCoy Chevrolet on 45 and [redacted] in Houston, Texas. They included a warranty for oil changes and tire rotations in my payments, but when I went for an oil change recently, they informed me the warranty had expired. Additionally, an inspection sticker was removed from my truck during a previous visit without any follow-up or investigation by the dealership. The last time I had an issue, another manager helped me and assured me I still had oil changes remaining, providing me with his contact information which I have misplaced. I have been a loyal GMC customer.

I have a [redacted] Buick Regal Base with [redacted],[redacted] miles that has a common Shift to Park issue affecting some GM vehicles. This problem is draining my battery, and Moran Buick in Taylor will be charging approximately $[redacted] to fix it, including a new shift knob and control module. I am hoping that GM can offer me some form of compensation, like a secret warranty or a discount on parts and labor. I am a loyal Buick customer who has owned three Buicks over the past 15 years. Your help on this matter would be greatly appreciated. Thank you. - Robert C.

I purchased a [redacted] GMC Denali from Lafontain Auto Group in Lansing, MI in late July [redacted]. I've enjoyed the truck and its features for 14,[redacted] miles before experiencing a lifter collapse in the left lifter bank. The truck was towed to the dealership and repaired on-site. I requested a new engine with a new warranty or a new truck with the same equipment, which I believe is reasonable given the lost value and the seriousness of the upper engine repair. With only five months of use and well within the mileage warranty, our confidence in this equipment has been shaken. As a loyal GMC customer, I value the dependability that Professional Grade represents. Despite GM being a global corporation, I prefer to support local businesses and have been a loyal customer for 18 years, having purchased a total of 9 autos and 11 1/2 to 1-ton trucks, all 4x4s. I mention Mr. John Grettinberger, who was a client of mine and the former general manager of the North America Cadillac division. While new [redacted] trucks have arrived at the dealership, I am not willing to pay an additional $10,[redacted] for a new truck after driving only 14,[redacted] miles. I hope we can find a positive resolution and continue to stay within the GM family. I prefer verbal communication on this matter. Sincerely, C. Patterson

On February 14, [redacted], I had to have my car repaired, costing me $[redacted].13. My [redacted] Buick Encore, with only 32,[redacted] miles, is solely owned by me. The car had issues and was taken to my mechanic for diagnosis. The problem was a Misfire Find in the Ignition Coil cassette, which was burnt through and needed replacement. After researching, I found this issue shouldn't occur at such low mileage. I possess the damaged part for your inspection. Due to the Coil replacement, the spark plugs were also replaced. The cracked and burnt Coil indicates a problem. I would appreciate a response as I had to borrow the money for this unexpected expense. Please reach out to me via email at [redacted] Maryann C. [redacted] N. Victoria Ave Ventnor City, NJ [redacted]

I have learned that the Corporate office has sent a letter to dealers informing them that excessive markups on C8 Corvettes will lead to a reduction in their Corvette allocation. I am in Alpharetta, Georgia, north-east of Atlanta, struggling to find a C8 Corvette that is not marked up $20k to $80k above MSRP. Despite attempting to negotiate with a dealer for a [redacted] Vette marked up $20k, they claim they cannot lower the price due to lack of room for negotiation. It's apparent they have the $20k profit margin to work with until reaching MSRP. Waiting 1 to 2 years for a C8 at MSRP is unreasonable for us in our 80s. I support capitalism, yet allowing such markups may deter consumers from buying. Ending this practice will prevent buyers from being upside down on their purchase. While I understand not controlling private sellers, permitting dealerships to mark up vehicles adversely impacts potential buyers like myself. I urge Corporate to stop these excessive markups for the benefit of consumers like myself. Thank you.
