Lemon law eligibility depends on state law, number of repair attempts, and days out of service. Consult an attorney for actual eligibility.
Worn chain tensioners cause timing chain skip or snap — common on GM 5.3L/6.2L, Ford EcoBoost, VW/Audi EA888, BMW N47/N63. Listen for cold-start rattles.
Water pump failure causes rapid overheating. If the engine overheats even once, head gasket damage is likely — turning a $400 part into a $3,000+ repair.
Degraded transmission fluid destroys clutch packs and solenoids. CVT transmissions are especially sensitive — neglected fluid can result in a $4,000–$8,000 replacement.
On 4WD/AWD vehicles, neglected differential or transfer case fluid causes metal-on-metal wear. Replacement costs $1,500–$4,000.
Degraded coolant loses corrosion inhibitors and attacks aluminum engine components. Can cause head gasket failure and water pump corrosion.
Worn spark plugs cause misfires that can foul and crack catalytic converters. A $150 tune-up can prevent a $1,200 catalytic converter replacement.
Dirty or failing injectors cause rough idle, reduced fuel economy, and increased emissions. Cleaning costs $100–$200; replacement $800–$1,600.

SEAT BELTS:REAR/OTHER
SummaryGeneral Motors LLC (GM) is recalling certain 2018-2019 Cadillac CT6, Escalade ESV, Chevrolet Suburban, Volt, and GMC Yukon XL vehicles. Certain second-row or third-row rear seatbelts retractor assemblies may not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."Read full details...

SEATS:MID/REAR ASSEMBLY
SummaryGeneral Motors LLC (GM) is recalling certain 2016-2018 Cadillac CT6 vehicles. The inboard child seat anchorage bars may have had excess structural adhesive applied during assembly, which can interfere with the installation of a child seat. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 225, "Child Restraint Anchorage Systems."Read full details...

The blue line shows 9 NHTSA complaints on file for the CADILLAC CT6 — a relatively low volume that spans from 2018 to 2025.
The amber reliability line averaged 94/100 across the vehicle's life — relatively stable, with the lowest point of 88/100 in 2020.
8-speed automatic transmissions (8L90 and 8L45) exhibit a shuddering or shaking sensation during light acceleration, especially at highway speeds. GM issued multiple TSBs and extended coverage programs. The fix involves a fluid exchange with a revised fluid formulation and, in persistent cases, torque converter replacement.
Coverage eligibility depends on your VIN, original sale date, and current mileage. Always verify with an authorized dealer or manufacturer customer service — programs may have been updated since this database was compiled.
Estimates use EPA fuel economy data, AAA 2024 national averages for insurance and maintenance, and a standard depreciation curve. Actual costs vary by location, driving habits, and vehicle condition.
Estimated 5-year cost of ownership: $43,455 (~$724/mo). Repair risk buffer is standard due to vehicle risk profile.
Based on original MSRP of $84,295 with luxury depreciation curve. Range reflects ±15% market variance. Actual value depends on condition, options, and local demand.
