Buick Regal Repair & Maintenance in Winston-Salem, NC

Buick Regal Repair & Maintenance in Winston-Salem, NC

Professional Service for Every Buick Regal Generation

The Buick Regal blends European driving dynamics with American comfort and luxury. Whether you drive a classic early-2000s model or a recent GS with sport-tuned suspension, the Regal demands specialized attention to stay reliable. That’s where Carolina Mobile Auto Service comes in. Based in Winston-Salem, we offer top-tier repair and maintenance for all Buick Regal models, from oil leaks and suspension issues to turbocharger problems and advanced diagnostics.

Why Trust Carolina Mobile Auto Service?

Your Buick Regal is a unique vehicle. Earlier models emphasized smooth rides and spacious interiors, while later Regals featured turbocharged engines and all-wheel drive — especially in the GS trims.

We combine dealership-level tools with local integrity — meaning no upselling, fast turnarounds, and expert service you can trust.

Common Buick Regal Problems by Generation

✅ 6th Generation (2011–2017)

  1. Transmission Failure (6-speed auto):
     Reported in 2011–2013 models, this includes hard shifting, slipping, or total failure. Solenoid and valve body defects were common. GM issued TSBs for calibration and updates.

  2. Turbocharger Failure (2.0L Turbo):
     Premature turbo failure or low boost pressure typically occurs around 80,000–100,000 miles. Symptoms include loss of power, engine noises, and check engine lights. Oil supply issues often cause bearing wear.

  3. Electrical Gremlins:
     The IntelliLink infotainment system may crash, freeze, or reboot. Other reports include power windows not responding or accessory fuse box issues.

  4. Water Pump Leaks:
     2.4L and 2.0L engines both have reports of coolant leaks from the water pump or thermostat housing. If left unchecked, this leads to overheating.

  5. Timing Chain Stretch (2.4L):
     Like other GM Ecotec engines, the 2.4L version in the Regal may suffer from timing chain stretch and associated check engine lights.

✅ 7th Generation (2018–2020)

  1. 9-Speed Transmission Issues (FWD models):
    Regal Sportback models equipped with GM’s 9T65 9-speed automatic have been reported to exhibit harsh shifts, especially from 1st to 2nd gear. GM issued software updates for shift mapping.

     

  2. AWD System Faults (TourX models):
     TourX wagon and GS trims with AWD systems have had electronic differential lock failures and noise from the rear drive module.

     

  3. Oil Consumption (2.0L Turbo):
     Direct-injected 2.0L engines can experience excessive oil consumption. Causes include PCV system defects, worn rings, or valve seal failure.

     

  4. Start/Stop System Complaints:
     Some drivers experience rough or inconsistent restarts, especially during hot weather or with weak batteries.

     

  5. Suspension Clunks (GS Trims):
     The sport-tuned suspension in GS models may develop clunking noises due to premature wear of strut mounts or sway bar links.

⚠️ Common Problem Areas & Repair Advice

Transmission Issues — Across Multiple Generations

  • Regal transmissions commonly include the 4T60-E, 4T65-E, and 6T45 (in later generations). While generally robust, these units can suffer from slipping gear changes, harsh shift behavior, and torque converter issues—especially in 2011–2013 models.

  • Symptoms include delayed shifts, rough engagement, or stalling during light throttle, especially steps from 1st to 2nd gear. Owners have noted transient shake or shudder around 13–15 mph in the 2.0L turbo variants.

  • Experts emphasize early diagnosis—fluid checks, control module reset, solenoid inspection—and call for rebuilds when internal wear becomes severe.

2.0L Turbo Engine Problems

  • Turbo models in mid‑2010s Regals experience excessive oil consumption, turbo bearing wear, misfires, and overheating issues. Cold starts sometimes trigger misfire or hesitation due to clogged injectors or worn seals.

  • Causes include poor PCV system performance, piston ring wear, and inadequate oil supply to turbochargers—regular oil monitoring and high-quality lubes are critical.

Electrical & Accessory Complaints

  • Owners report failures in the IntelliLink infotainment system, power windows, accessory modules, and fuel gauges that jump or freeze at low levels.

  • The brand averages 238 total issues across various systems—placing it around 8th in reliability among Buick models. Many involve engine sensors and module errors.

  • Common HVAC or lighting faults often relate to failing module connections or actuator motors, requiring precise OEM-level diagnostics.

Cooling, Fuel & Mechanical Wear

  • Reports document intake manifold gasket leaks and coolant leaks tied to Dexcool compatibility issues—leading to overheating or engine performance loss.

  • Some owners experienced stalling caused by camshaft timing control valves, remedied by sensor replacements and module reprogramming.
