Buick Enclave jerks during acceleration and experiences loud speaker noise, especially uphill on Buick Enclave

Some Buick Enclave owners report experiencing jerking during acceleration due to various issues, including a misfiring engine often linked to faulty spark plugs or coil packs. Additionally, transmission problems may manifest as shaking or clunking sensations, particularly around 90,000 miles. Second-generation Buick Enclave owners have noted brake issues, such as screeching noises and brake fluid leaks, which can also contribute to the jerking sensation. Clogged injectors are another common culprit, disrupting acceleration at low speeds. Furthermore, faulty spark plugs are frequently identified as a cause of this jerking, and they are generally straightforward to replace. First-generation Buick Enclave owners have reported loud engine and transmission noises, especially when going uphill, alongside concerns regarding steering and suspension problems, including strut replacements and rack and pinion leaks. It is advisable for owners experiencing these issues to consult a mechanic for a thorough inspection of the spark plugs, coils, transmission, brakes, and steering components to ensure effective diagnosis and resolution.
